Because doctors sometimes have to inflict pain on their patients as part of the healing process, they also must develop the ability to not be distracted by the suffering, said Jean Decety, Professor in Psychology and Psychiatry at the University and co-author of “Expertise Modulates the Perception of Pain in Others,” published in the Oct. 9 issue of Current Biology and currently available on-line.

Bird Flu Virus Mutating into Human-Unfriendly Form
October 4, 2007 08:37 PM - Maggie Fox, Health and Science Editor
NEW YORK (Reuters) - The H5N1 bird flu virus has mutated to infect people more easily, although it still has not transformed into a pandemic strain, researchers said on Thursday.
The changes are worrying, said Dr. Yoshihiro Kawaoka of the University of Wisconsin-Madison.
"We have identified a specific change that could make bird flu grow in the upper respiratory tract of humans," said Kawaoka, who led the study.
"The viruses that are circulating in Africa and Europe are the ones closest to becoming a human virus," Kawaoka said.
CDC suspects 29 E.coli cases linked to Topps beef
October 4, 2007 08:27 PM -
CHICAGO (Reuters) - The U.S. Centers for Disease Control and Prevention said 29 cases of E.coli illness are suspected to be linked to the 21.7 million lbs of recalled ground beef products from Topps Meat Company LLC.
No deaths have been linked to the meat. The 29 cases were in eight states: Connecticut (two cases), Florida (one), Indiana (one), Maine (one), New Jersey (six), New York (nine) Ohio (one) and Pennsylvania (eight), according to a posting on the CDC's Web site.
Bird Flu Virus "More Invasive Than Thought'

BEIJING - The post mortems of two people who died after H5N1 infection have revealed that the virus infects more human organs than previously thought. The study was published in The Lancet. Lead author Gu Jiang, a professor at the School of Basic Medical Sciences of the Beijing-based Peking University, and colleagues studied post-mortem tissues of one man and one pregnant woman, and also tested the foetus of the woman.
Study: Vitamin C Essential For Plant Growth
October 4, 2007 07:38 PM -
University of Exeter - Scientists from the University of Exeter and Shimane University in Japan have proved for the first time that vitamin C is essential for plant growth. This discovery could have implications for agriculture and for the production of vitamin C dietary supplements.The study, which is published in The Plant Journal, describes the newly-identified enzyme, GDP-L-galactose phosphorylase, which produces vitamin C, or ascorbate, in plants. Vitamin C is already known to be an antioxidant, which helps plants deal with stresses from drought to ozone and UV radiation, but until now it was not known that plants could not grow without it.
U.S. Recalls over 1/2 Million Toys for Lead Levels
October 4, 2007 03:35 PM - Reuters
WASHINGTON (Reuters) - More than half a million toys ranging from key chains to Winnie the Pooh bookmarks and Baby Einstein color blocks are being recalled because of excessive lead levels, the Consumer Product Safety Commission said on Thursday.
Among the recalled toys, all made in China, were key chains with words like "truth" or "believe" engraved on them that have "high levels" of lead, the commission said in a statement.
Dollar General Merchandising Inc sold 192,000 of the key chains for $1, the CPSC said.
Lead is toxic in large amounts. A 4-year-old Minneapolis boy died of lead poisoning in 2006 when he swallowed a small charm. In smaller amounts, lead can cause developmental delays and behavioral problems.
Could Drinking Puffer Fish "Pop" KO Karoshi or Can Jellyfish Juice Take the Sting Out of Alzheimer's
October 4, 2007 08:29 AM - Nurition Horizon PR
Japan - Beverage companies are working on a safe fugu (puffer fish) extract to be used in Japanese energy drinks, the fish is highly toxic, but despite this or perhaps because of this deadly side effect, it is considered a delicacy among the Japanese. Puffer fish (Sphoeroides testudineus) poisoning results from the ingestion of fish containing the deadly nerve toxin called tetrodotoxin and it is the most common and lethal form of marine poisoning in Japan.
Researchers Discover Link Between Schizophrenia, Autism and Maternal Flu
October 3, 2007 08:05 PM -
PASADENA, Calif.- A team of California Institute of Technology researchers has found an unexpected link connecting schizophrenia and autism to the importance of covering your mouth whenever you sneeze.
It has been known for some time that schizophrenia is more common among people born in the winter and spring months, as well as in people born following influenza epidemics. Recent studies suggest that if a woman suffers even one respiratory infection during her second trimester, her offspring's risk of schizophrenia rises by three to seven times.
Since schizophrenia and autism have a strong (though elusive) genetic component, there is no absolute certainty that infection will cause the disorders in a given case, but it is believed that as many as 21 percent of known cases of schizophrenia may have been triggered in this way. The conclusion is that susceptibility to these disorders is increased by something that occurs to mother or fetus during a bout with the flu.
To Treat Patients Doctors' Alter Own Pain Responses: Study
October 3, 2007 07:31 PM -
CHICAGO - Physicians apparently learn to “shut off” the portion of their brain that helps them appreciate the pain their patients experience while treating them and instead activate a portion of the brain connected with controlling emotions, according to new research using brain scans at the University of Chicago.
DNA test could detect cervical cancer early: study
October 3, 2007 07:15 PM - Michael Kahn, Reuters
LONDON (Reuters) - A DNA test for the virus that causes cervical cancer helps detect potentially dangerous lesions earlier than the commonly used pap smear technique, Dutch researchers said on Thursday.
The test could mean fewer screenings for women and ensure that they receive earlier treatment for lesions that might lead to cancer, they said in the journal Lancet.
"It is a better test because you pick up more lesions," Chris Meijer, a pathologist at VU University Medical Centre in Amsterdam, said in a telephone interview. "And because you pick them up earlier, you have more time to treat the women."
Contraception Ban Harms Philippine Women

Our new report, "Imposing Misery," documents the impact of Manila's contraception ban on women and their families. It was a joint effort between three groups: the International Legal Program here at the Center for Reproductive Rights; Likhaan, a women's health organization based in Quezon City, Philippines; and ReproCen, a reproductive rights and health organization based at the University of the Philippines in Manila.
