Is This the Face of Jack The Ripper?

Thin-haired with deep-set grey eyes and a large, red pimpled nose: this is how Jack the Ripper, perhaps the most notorious murderer in history, might have looked, according to new archival research into police documents.

Retired British police detective, Trevor Marriott, gathered together evidence and has built a case against Carl Feigenbaum, a 54-year-old German merchant seaman, and made him the top suspect for committing the horrific and notorious murders between August and November 1888.

At that time, at least five women in the Whitechapel area in London were found horribly disfigured, often with organs missing.

The name Jack the Ripper was coined in taunting letters sent to the press and police, in which the writer claimed credit for the crimes.

Ripper's career ended as suddenly as it began with the murderer still at large, making his case one of the history's greatest murder mysteries.

Since the first murder 123 years ago, more than 200 suspects have been named, including Lewis Carroll, author of "Alice in Wonderland," Prince Albert Victor and Sir John Williams, obstetrician to the Royal Family.

According to Marriott, there are a number of factors pointing to the obscure German merchant.

"For example, he killed a woman in ripper like fashion with a long bladed knife which he carried. It was the same type of knife used to kill the Whotechapel victims," Marriott told Discovery News.

The murder occurred in Manhattan, and the woman was his landlady Juliana Hoffman.

For the brutal killing, Feigenbaum went to the electric chair in New York in 1896.

Marriott begun his investigation by examining groups of people who may have been in Whitechapel at the time of the killings.

Since the district is just a short distance from London's docks, sailors were included in the group of suspects.

Crew lists for ships that were in dock at those times revealed that Feigenbaum, who was already in the 200 suspect list, was visiting London at the time of each murder.

"He had been employed as a merchant seaman for The Nordeutcher Line which had a ship in London on all the murder dates," Marriott said.

The former detective also found a 1896 report in the National Police Gazette in which Feigenbaum’s lawyer detailed a confession made by his client at Sing Sing jail.

"I have for years suffered from a singular disease, which induces an all-absorbing passion; this passion manifests itself in a desire to kill and mutilate the woman who falls in my way. At such times I am unable to control myself," he confessed.

No photographs of Feigenbaum exist, but Marriott put together an e-fit based on the description of him when he was in prison in the US.

According to the Sing Sing admittance form, he had deep set grey eyes, dark brown hair and a "medium sized head."

Standing 5ft 4½ tall and weighting 126 pounds, he had a large, red nose with raw pimples, with poor teeth, almost entirely gone on left sides.

The prison official also noted he had "anchor in india ink on right hand at base of thumb and first finger" and a "round scar or birthmark on right leg below left knee."

Given the surgical precision of the mutilations, it was usually assumed that the elusive killer had a great knowledge of human anatomy.

But Marriott argued that the removal of the women's organs occurred in the mortuary, as the 1832 Anatomy Act made it legal to remove organs for medical training.

Why We Crave Creativity but Reject Creative Ideas

Most people view creativity as an asset -- until they come across a creative idea. That's because creativity not only reveals new perspectives; it promotes a sense of uncertainty.

The next time your great idea at work elicits silence or eye rolls, you might just pity those co-workers. Fresh research indicates they don't even know what a creative idea looks like and that creativity, hailed as a positive change agent, actually makes people squirm.

"How is it that people say they want creativity but in reality often reject it?" said Jack Goncalo, ILR School assistant professor of organizational behavior and co-author of research to be published in an upcoming issue of the journal Psychological Science. The paper reports on two 2010 experiments at the University of Pennsylvania involving more than 200 people.

The studies' findings include:

•     Creative ideas are by definition novel, and novelty can trigger feelings of uncertainty that make most people uncomfortable.
•     People dismiss creative ideas in favor of ideas that are purely practical -- tried and true.
•     Objective evidence shoring up the validity of a creative proposal does not motivate people to accept it.
•     Anti-creativity bias is so subtle that people are unaware of it, which can interfere with their ability to recognize a creative idea.

For example, subjects had a negative reaction to a running shoe equipped with nanotechnology that adjusted fabric thickness to cool the foot and reduce blisters.

To uncover bias against creativity, the researchers used a subtle technique to measure unconscious bias -- the kind to which people may not want to admit, such as racism. Results revealed that while people explicitly claimed to desire creative ideas, they actually associated creative ideas with negative words such as "vomit," "poison" and "agony."

Goncalo said this bias caused subjects to reject ideas for new products that were novel and high quality.

"Our findings imply a deep irony," wrote the authors, who also include Jennifer Mueller of the University of Pennsylvania and Shimul Melwani of the University of North Carolina, Chapel Hill. "Revealing the existence and nature of a bias against creativity can help explain why people might reject creative ideas and stifle scientific advancements, even in the face of strong intentions to the contrary."

New ‘Demon’ Bat Species Found in Vietnam

Three new bat species, one resembling the Lord of the Underworld, have been discovered in the tropical forests of southern Indochina.

The tiny ‘demon,’ named Beelzebub’s tube-nosed bat, has been seen only in Vietnam.

“We chose the name Beelzebub to reflect the dark ‘diabolic’ coloration of the new species and its fierce protective behavior in the field,” said Gabor Csorba of the Hungarian Natural History Museum.

Bats represent nearly a third of the known mammal species in South East Asia already. But the true number of bat species in the region may be twice current count, based on recent genetic research, said Paul Racey, bat specialist and Vice Chairman of Fauna and Flora International, in a press release today.

Murina beelzebub, like the other two tube-nosed bats discovered, depends on the tropical forest for its survival. The bats are especially vulnerable due to ongoing deforestation in the region, researchers warn.

First Long-Term Study of WTC Workers Shows Widespread Health Problems 10 Years After Sept. 11

In the first long-term study of the health impacts of the World Trade Center (WTC) collapse on September 11, 2001, researchers at The Mount Sinai Medical Center in New York have found substantial and persistent mental and physical health problems among 9/11 first responders and recovery workers.

The data are published this week in a special 9/11 issue of the medical journal The Lancet.

The Mount Sinai World Trade Center Clinical Center of Excellence and Data Center evaluated more than 27,000 police officers, construction workers, firefighters, and municipal workers over the nine years following 9/11 and found a high incidence of several conditions, including asthma, post-traumatic stress disorder (PTSD), depression, sinusitis, and gastroesophageal reflux disease (GERD). More than one in five of all the responders studied had multiple physical and/or mental health problems.

The results showed that nine years after 9/11:

•     28 percent of patients had asthma, 42 percent had sinusitis, and 39 percent had GERD.
•     42 percent of patients had abnormal lung function tests, indicative of lung injury.
•     7 percent of police officers were diagnosed with depression, 9 percent with PTSD and 8 percent with panic disorder.
•     28 percent of other rescue and recovery workers had symptoms of depression; 32 percent experienced symptoms of PTSD, and 21 percent had symptoms consistent with panic disorder.
•     Almost 10 percent of rescue and recovery workers had asthma, sinusitis, and GERD simultaneously.
•     48 percent of rescue workers with asthma, 38 percent with sinusitis, and 43 percent with GERD were also diagnosed with at least one mental health condition.

"Several studies have evaluated the health impacts of 9/11, but this is the first long-term study to demonstrate the lasting burden of disease experienced by the brave men and women who responded in the aftermath of the terrorist attacks at the World Trade Center," said Juan Wisnivesky, MD, DrPH, Vice-Chair for Research in the Department of Medicine and lead author on the study. "Our findings underscore the importance of long-term monitoring and treatment of the rescue and recovery worker population."

Those who arrived on the scene first received the greatest exposure to the dust and smoke, and sustained the most severe health damage. These first responders were exposed to a complex mix of toxins and known human carcinogens that included benzene from jet fuel, asbestos, dioxin, lead, polycyclic aromatic hydrocarbons (PAHs), glass fibers, hydrochloric acid, polychlorinated biphenyls, and other caustic chemicals. All of these materials were released into the air of lower Manhattan with the collapse of the towers. Participants were divided into four categories based on their level of exposure to airborne toxins at Ground Zero. Fourteen percent were categorized as low exposure, 65 percent as intermediate, 18 percent high, and 3 percent as very high.

Quantum computer chips pass key milestones

Quantum computer users may soon have to wrestle with their own version of the "PC or Mac?" question. A design based on superconducting electrical circuits has now performed two benchmark feats, suggesting it will be a serious competitor to rival setups using photons or ions.

"The number of runners in the race has just gone up to three," says Andrew White of the University of Queensland, Australia, who builds quantum computers based on photons and was not involved in the new result.

The defining feature of a quantum computer is that it uses quantum bits or qubits. Unlike ordinary bits, these can exist in multiple states at once, known as a superposition. They can also be entangled with each other, so their quantum states are linked, allowing them to be in a sort of "super" superposition of quantum states.

This means quantum computers could perform multiple calculations simultaneously, making them much faster than ordinary computers at some tasks.

Previously, setups using photons or trapped ions as qubits have made the most headway in early calculations. Now Matteo Mariantoni of the University of California, Santa Barbara, and colleagues have boosted the computing power of a rival design, first demonstrated in 2003, that uses tiny, superconducting wires instead.

Wire loops

Mariantoni's team used a chip embedded with micrometre-sized loops of wire made of a mixture of aluminium and rhenium. When these wires were cooled to within a whisker of absolute zero, they became superconducting, meaning their electrons coupled up as structures called "cooper pairs".

The pairs in each wire were made to resonate as an ensemble. Because each ensemble could exist as a superposition of multiple different resonating states, they acted as qubits.

Mariantoni's team entangled these qubit wires using a second type of wire, known as a bus, that snaked all around the chip. First they tuned this bus so that it took on some of the quantum information in one of the qubits. Then they transferred this information to further qubit wires, thus entangling the qul�.

Benchmark tests

The design made strides in solving calculations often used as benchmarks for testing quantum computers' capabilities.

It ran a calculation known as the quantum Fourier transform, which is a central component of the most famous quantum algorithm, known as Shor's. If Shor's were run on a system with enough qubits, it would allow huge numbers to be factorised quickly. That has not happened yet, but if it ever did, it would cause many current encryption systems to break down, since they rely on the fact that ordinary computers can't do this.

The researchers also used entangled qubits to create a system known as a "Toffoli OR phase gate", which is a critical step towards building codes that do quantum error correction. This required entangling three qubits – a first for superconducting quantum circuits. "Getting three bits to play well together is hard," says White.

Oldest Advanced Tools Found in Kenya

Given that chimps have demonstrated the ability to make and use tools in the wild, chances our that our human ancestors inherited some of that ability from the ancestor both humans and chimps have in common. But, starting with the australopithecines, our ancestors started making permanent tools from rocks, and investing increased effort into shaping. Oldowan tools were later used by the first members of the genus Homo, and were carried out of Africa during the global spread of Homo erectus.

By 1.4 million years ago, African Homo erectus was using the far more involved and sophisticated Acheulian tool technology, which later made its way out of Africa. But the transition between the two tool types has remained unclear. Now, scientists are reporting the first find where Oldowan and Acheulian tools have been found at the same site, one that’s old enough to indicate that Acheulian tools were available when Homo erectus first left Africa.

The site in question lies near Lake Turkana in Kenya, which was already famous for finds relevant to human origins, including the Turkana Boy Homo erectus skeleton, which dates from 1.5 million years ago. The slopes near the northwest shore of the lake contain an extensive sedimentary record that can be matched with others in the nearby area, including some that have been dated using radioactive decay. A few meters below the sediments that contained the tools lies a feature that has been dated to 1.9 million years ago; above them, a different feature sets a younger limit at 1.5 million years. That last figure is rather significant, given that there are no reliably dated Acheulian tools older than 1.4 million years.

Extrapolating based on the depth of the deposits between, the authors estimate that the tools are roughly between 1.72 and 1.81 million years old. That lets them start zeroing in on a more precise date based on reversals in the Earth’s magnetic field. This provides a firmer estimate: 1.76 million years, 350,000 years older than the previous site that had been dated so precisely. It also lines up with one of the earliest Homo erectus fossils, reinforcing the link between the two.

Since both toolmaking technologies were present in the same sediments, the site provides a clear indication that one set of techniques didn’t simply replace the others. Either the Acheulian tools were developed by people who continued to use their earlier techniques, or the Acheulian technology was imported without its displacing the native one. In either case, the site suggests a more gradual transition than previous evidence had indicated.

Body of Infamous Aussie Outlaw Ned Kelly Found

The headless remains of the infamous Australian outlaw Ned Kelly have finally been identified, officials said Thursday, solving a mystery dating back more than 130 years.

Considered by some to be a cold-blooded killer, Kelly was also seen as a folk hero and symbol of Irish-Australian defiance against the British authorities.

After murdering three policemen, he was captured in Victoria state in 1880 and hanged at Old Melbourne Gaol in November of the same year. But his body went missing after it was thrown into a mass grave.

The bodies in the grave were transferred from the jail to Pentridge Prison in 1929 and then exhumed again in 2009. The investigation into Kelly began when a skull believed to be his -- and stolen in 1978 -- was rediscovered.

Doctors and scientists at the Victorian Institute of Forensic Medicine identified his body, found in a wooden axe box, after a DNA sample was taken from Melbourne teacher Leigh Olver, Kelly's sister Ellen's great-grandson.

"The wear and tear of the skeleton is a little bit more than would be expected for a 25-year-old today," said institute director Professor Stephen Cordner.

"But such was Ned's life, this is hardly surprising."

However, tests found that the skull believed to be Kelly's was in fact not his.

Victoria's Attorney-General Robert Clark said he was amazed by the work of the forensic scientists.

"This is an extraordinary achievement by our forensic team," he said.

"To think a group of scientists could identify the body of a man who was executed more than 130 years ago, moved and buried in a haphazard fashion among 33 other prisoners, most of whom are not identified, is amazing."

Believed to have been born in 1854 or 1855, Kelly became an outlaw two years before he was hanged, taking on corrupt police and greedy land barons.

He survived a shootout with police in 1878 that saw him, his brother Dan, and friends Joe Byrne and Steve Hart slapped with an 8,000-pound bounty -- the largest reward ever offered in the British Empire -- for anyone who found them, dead or alive.

Over the next 18 months, the Kelly Gang held up country towns and robbed their banks, becoming folk heroes to the masses.

In a final gunbattle at Glenrowan, three of the gang members died and Kelly, dressed in home-made plate metal armour and helmet, was wounded and arrested.

Photos of his skeletal remains clearly show a bullet hole in one of his leg bones.

Shaggy, Shovel-Headed Rhino Evolved in Tibet

Woolly rhinos and many other large, shaggy prehistoric animals first evolved their cold tolerance in Tibet, which served as the evolutionary cradle for Ice Age mega plant-eaters, according to a new paper.

The study helps explain why so many different species roamed North America, Europe and Asia during the last Ice Age beginning about 2.8 million years ago. They had previously adapted to cold environments in the western Himalayas before later expanding to other regions.

Several were big with long hair.

"There is a general principle, called Bergmann's Rule, that suggests animals tend to increase their body size in colder environments," said Xiaoming Wang, co-author of the study which appeared in this week's Science. "Large-bodied animals have relatively smaller surface areas to lose heat and thus conserve heat better -- it's a matter of physics."

Wang and his colleagues identified Tibet as the mega herbivore cradle after discovering a new woolly rhino, Coelodonta thibetana, dating to 3.7 million years ago. As its name suggests, this animal was about as furry as a beast can be, and it had a head that functioned like a snow shovel.

"The extinct Tibetan woolly rhino had developed special adaptations for sweeping snow using its flattened, forward-leaning horn to reveal vegetation, a useful behavior for survival in the harsh Tibetan climate," Wang explained.

He and his team suspect that the rhino evolved from Stephanorhinus, a genus of Eurasian-wide distribution. C. thibetana then lived during the Pliocene (5.3 to 2.6 million years ago) at a time, Wang said, "when global climate was much warmer and the northern continents were free of the massive ice sheets seen in the Ice Age later. The Tibetan rhino likely was thus able to accustom itself to cold conditions in high elevations and become pre-adapted for the future Ice Age climate."

Tibet also gave rise to other cold-adapted animals. While woolly mammoths and woolly rhinos bit the proverbial dust some time ago, other species with Tibetan ancestry survived to modern times.

The Tibetan wild yak, for example, is a sister species to European and North American bison. During the Pleistocene, the Tibetan wild ass expanded its population to northern Pakistan and possibly even to Alaska. Snow leopards and blue sheep are two other examples.

"Like the woolly rhino, blue sheep descended down from high Tibet during the Ice Age, presumably for the same reason as the rhinos, but somehow the blue sheep survived to the present day in the high plateau," Wang said.

The Tibetan antelope is now confined to the highest elevations of Tibet and adapted "by evolving one of the finest under furs," often used by local people to weave highly prized shawls.

The Tibetan antelope and virtually all other modern, cold-hardy species are now under threat due to climate change and over-hunting. According to Wang, "The polar bear is a poster child example" of such animals that are presently at risk.

Animal experts largely agree that Tibet was indeed the birthplace for many species that later survived through the Ice Age and beyond.

"We know from today's species that they move up and down mountains in accordance with climate change," said Adrian Lister, a professor in the Department of Paleontology at The Natural History Museum in London. Lister added that "many are now moving upwards" in an attempt "to escape global warming. It seems perfectly reasonable that a similar thing could have happened over longer time scales in the past."

Graphene's Shining Light Could Lead to Super-Fast Internet

Writing in the journal Nature Communications, a collaboration between the Universities of Manchester and Cambridge, which includes Nobel Prize winning scientists Professor Andre Geim and Professor Kostya Novoselov, has discovered a crucial recipe for improving characteristics of graphene devices for use as photodetectors in future high-speed optical communications.

By combining graphene with metallic nanostructures, they show a twenty-fold enhancement in harvesting light by graphene, which paves the way for advances in high-speed internet and other communications.

By putting two closely-spaced metallic wires on top of graphene and shining light on this structure, researchers previously showed that this generates electric power. This simple device presents an elementary solar cell.

More importantly for applications, such graphene devices can be incredibly fast, tens and potentially hundred times faster than communication rates in the fastest internet cables, which is due to the unique nature of electrons in graphene, their high mobility and high velocity.

The major stumbling block towards practical applications for these otherwise very promising devices has so far been their low efficiency. The problem is that graphene -- the thinnest material in the world -- absorbs little light, approximately only 3%, with the rest going through without contributing to the electrical power.

The Manchester researchers have solved the problems by combining graphene with tiny metallic structures, specially arranged on top of graphene.

These so-called plasmonic nanostructures have dramatically enhanced the optical electric field felt by graphene and effectively concentrated light within the one-atom-thick carbon layer.

By using the plasmonic enhancement, the light-harvesting performance of graphene was boosted by twenty times, without sacrificing any of its speed. The future efficiency can be improved even further.

Dr Alexander Grigorenko, an expert in plasmonics and a leading member of the team, said: "Graphene seems a natural companion for plasmonics. We expected that plasmonic nanostructures could improve the efficiency of graphene-based devices but it has come as a pleasant surprise that the improvements can be so dramatic."

Professor Novoselov added: "The technology of graphene production matures day-by-day, which has an immediate impact both on the type of exciting physics which we find in this material, and on the feasibility and the range of possible applications.

"Many leading electronics companies consider graphene for the next generation of devices. This work certainly boosts graphene's chances even further."

Letters Home After 9/11

This is a letter I wrote to my hometown minister, Scott Planting, the Saturday after the 9/11 attacks. My mother, who had a copy, recently sent it to me and it brought back a flood of memories. Sometimes, memories of events as tumultuous as 9/11 can fade or change over time. I think it's important that we remember that day -- those days -- as they were at that moment. That's why we're asking you to contribute as well. Did you write letters or emails after 9/11 that you could share?

We're compiling a collection called Letters Home After 9/11 and would like to include yours. Please post your letter or email in the comments section below, or email them to amanda_onion@discovery.com, taking out any parts you'd like to keep personal. Thank you for helping us document reflections and memories of that wrenching day 10 years ago.

Saturday, Sept. 15, 2001
Hi Scott,

I heard you were interested in hearing what it's like here. I, and I think most people here haven't really yet come to grips with what happened. The whole city is walking around in a daze, in some kind of horrible, never-ending nightmare.

I was at work at ABC when this happened and have been working ever since. Not really sleeping, barely eating. That morning I got to work at 8 am. At 8:20 we have a meeting to settle on what news we'll cover for the day. Since I cover science, I'm to write a story about how scientists have concluded that more stem cell lines are needed for research. Then, at 8:50, I hear someone in the newsroom say, "Oh my God."

We all look up at the TV monitors and see the unbelievable image of the upper floors of one tower of the World Trade Center burning and smoking. We learn a plane has crashed into it. We assume it was an accident. I call mom and tell her something terrible has happened.

The editors quickly gather and assign stories. I'm told to write a story about what allows the building to remain standing despite being struck by a plane. Then the next plane strikes. There's an audible moan from the newsroom. Now it's clear this is not an accident. It's clear the city is being attacked by terrorists.

For about an hour I can't track down a friend of mine. She was leaving for work shortly before the first plane struck. I leave several messages for her at home and work. I don't hear back until later. She's OK. She was on the train, above ground, when the second plane struck. People in the train watched it happened, cried out and then the train went back underground. They rode the rest of the way in shock.

I start making calls. I talk to structural engineers, some of whom had worked on the design of the World Trade Center. They begin to explain the buildings' complex architecture and how they could remain standing. It appears to be a testimony to the trade's ability.

I start to write my story. Then the first tower falls. We all feel sick. I start over again. I call everyone back. My story now is what caused the tower -- and eventually both towers -- to fall. After I file it I'm asked to go out and do some reporting.

I go outside and see streams of people walking briskly north. It seems like the entire city is walking, walking in the streets, in the sidewalks, in the parks. And they're all heading north, away from the nightmare that's in lower Manhattan. Many are carrying bags of bottled water and food. Many have heard that the city's water supply has been poisoned. I talk to people who have walked for miles -- everyone is scared. A plane flies overhead, everyone looks up, terrified. It's a fighter plane.

I go back to work and file the reporting. I begin hearing from friends and family. In a panic everyone in the city starts calling or emailing everyone they know. We're desperate to know if everyone's OK. Among my friends, one, someone I didn't knew very well, but a great guy with a huge smile, is still missing.

Another friend of mine was shopping at a store right next door to the World Trade Center at the time of the crash. He's a reporter for NBC News and his immediate instinct was to call his wife, also a reporter, and tell her to bring a camera and join him as he tries to report the story. She heads out. He approaches the towers. Now both are burning. He tries to go right up to the building, but a policeman stops him, saying he can't pass beyond that point, and telling him to clear out.

My friend argues with him, saying he's a reporter with NBC and he needs to cover the story. The police officer says no, he's yelling now, saying "Get out!" My friend walks away -- and then the first tower collapses. He runs for his life. Debris and shards pierce his back, he's covered in dust. But he survives. The place where the police officer had been standing is buried. My friend knows that police officer saved his life -- and had probably just lost his own.

Meanwhile my friend's wife has just arrived as the first tower crashes. She's terrified and starts phoning my friend on his cell phone trying to reach him. He doesn't answer, he doesn't answer, finally he does. Theirs is a happier story than many that we've heard.

That night, I'm not sure how or if I'll be able to get home. A friend walks 40 blocks from her office to mine so we can try getting back to Brooklyn together. We've heard some of the trains are still running and they are. After many long waits on eerie, empty platforms, many transfers and stopping and starting rides, we get home.

My bedroom, which has two windows facing lower Manhattan, is coated in fine debris. There's an acrid, sick, choking smell in the air. Plumes of black smoke still rise from Manhattan. Sirens sound all night. All of this continues still.

The next day I leave for work-at 5:30 a.m. the next day, and the next day. I get home late at night, call friends, family and go to bed. Many times as I'm working, I start to cry. Then I stop because I'm at work and we’re expected to perform. But I can't eat, can't sleep.

I think about the stunned look I've seen in other peoples' eyes in the trains on the way to work, on the streets I think about the time a few weeks ago that some friends and I went to the base of the World Trade Center to go shopping. I think about the maze of wide, gleaming hallways connecting buildings to other buildings, to subway lines, to stores. I think about how packed with people the buildings always were. I can't imagine it's all gone now. I can't imagine so many people are gone now -- even when I see the hole in the sky line, it still isn't real.

A friend and I walked downtown and went to a candlelight vigil outside in a park. Below 23rd street, every lamp post is plastered with hand-made posters. The posters an have pictures of someone with the words "Missing" above their smiling faces and a number to call if anyone has information.

On the sidewalks, people have written messages in chalk -- from Shakespeare, the bible, Gandhi and others. We've all seen little signs of desperation and diminishing hope. At my friend's apartment, she's noticed how the mail of one of her neighbor's has stacked up since Tuesday. No one has been there to collect it. Many of us have gotten calls, messages from strangers on our cell phones, asking for any information about a lost husband or wife.

I've been frustrated I haven't had time to volunteer, but among my friends who have tried, many have been turned away. They try to give blood, but are turned away. The hospitals are still waiting for patients, but they haven't arrived. Some of my friends visit their local fire departments and ask if they need anything. One unit, a squad that lost seven firefighters, asks her to bring some dinner and plastic utensils and plates. When we bring the food by, we realize that the station is not only staffed by surviving members of the crew, but also by an entire crew from Boston. Rescue workers from around the country have been streaming in to help.

Another friend is on her way home and encounters a woman who looks lost. She's a nurse who drove to New York from Rhode Island as soon as it happened on Tuesday. She's been volunteering at the disaster site and  isn't sure where to stay for the night. My friend takes her in.

Many of my friends have bought supplies -- plastic bags, bandages, ice, food -- to centers to help support the incredible rescue workers helping downtown. It seems like the job of clearing rubble and finding victims is going to take the rest of our lives. Mayor Rudolf Guiliani has been a pillar of light. He's telling New Yorkers to go on with their lives. He tells us to go to restaurants, to show that we will not be cowered by this cowardly act. Every night as I go home, I see the restaurants are packed.
