When Louis Wong came home from work earlier this week his wife brushed aside his attempt to hug their 2-year-old son and sent him straight to the shower.
Hong Kong is on flu alert after the unexplained deaths of four young children with flu-like symptoms. Worried residents are donning surgical masks, flooding hospital waiting rooms and buying up supplies of antibacterial soap as they remember the SARS outbreak that killed 299 people five years ago.
Depression is not always manifested in children as dejection and anhedonia. Depending on the age of the child, the dominant features may be weeping, irritability or defiance, as explained by Prof. Claudia Mehler-Wex and Dr. Michael Kölch of Ulm University in the new edition of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2008; 105(9): 149-55).
The signs of depression in infants are often screaming, restlessness, and weeping attacks for no clear reason. Preschool children may behave irritably and aggressively, while schoolchildren may be listless and apathetic. The symptoms in adolescents become similar to those in adults.
It's common knowledge that humans and other animals are able to visually judge depth because we have two eyes and the brain compares the images from each. But we can also judge depth with only one eye, and scientists have been searching for how the brain accomplishes that feat.
Now, a team led by a scientist at the University of Rochester believes it has discovered the answer in a small part of the brain that processes both the image from a single eye and also with the motion of our bodies.
The team of researchers, led by Greg DeAngelis, professor in the Department of Brain and Cognitive Sciences at the University of Rochester, has published the findings in the March 20 online issue of the journal Nature.
"It looks as though in this area of the brain, the neurons are combining visual cues and non-visual cues to come up with a unique way to determine depth," says DeAngelis.
A cup of black tea could be the next line of defence in the threat of bio-terrorism according to new international research.A new study by an international team of researchers from Cardiff University and University of Maryland has revealed how the humble cup of tea could well be an antidote to Bacillus anthracis --more commonly know as anthrax.
As a nation, Brits currently drink 165 million cups of tea, and the healing benefits of the nation's favourite beverage have long been acknowledged.
|A cup of black tea could be the next line of defence in the threat of bio-terrorism according to new international research.
But now the team of scientists led by Professor Les Baillie from Welsh School of Pharmacy at Cardiff University and Doctor Theresa Gallagher, Biodefense Institute, part of the Medical Biotechnology Centre of the University of Maryland Biotechnology Institute in Baltimore, has found that the widely-available English Breakfast tea has the potential to inhibit the activity of anthrax, as long as it is black tea.
A new class of painkillers that block a receptor called TRPV1 may interfere with brain functions such as learning and memory, a new study suggests. The experiments with rat brain found that the TRPV1 receptor regulates a neural mechanism called long-term depression, which is believed to be central to establishing memory pathways in the brain.

Army studies say one in three soldiers will return from Iraq with significant mental health problems, but the system isn't there to help them.
The seven qualities of leadership itemized in Army Field Manual (FM) 22-100 are loyalty, duty, respect, selfless service, honor, integrity and personal courage. Nowhere in that list is there any reference to heartlessness, lack of compassion and a cavalier disregard for the wellbeing of one's troops. And there is certainly no reference to posturing, denial or dissembling. Leading by example trumps mindless stoicism every time.

There will no doubt be a lot written about Eliot Spitzer's ethics, his hypocrisy and the damage done to his family, as well as discussions of the degradation that most prostitutes experience. He will be tarred and feathered for seeing a prostitute. And perhaps he should be, having broken vows to his wife, supporters and the citizens of New York State. As Spitzer takes his place with other politicians who have been busted for seeing a hooker, questions invariably arise: What is up with politicians screwing up their careers by visiting prostitutes? How can smart men do such incredibly dumb things? Does the attraction have something to do with power? Escape? Self-sabotage? For the moment, I want to put on my psychotherapist hat and try to explain what goes on in the deeper recesses of the minds of men like Spitzer.

Women with breast cancer have more aggressive disease and lower survival rates if they are overweight or obese, according to findings published in the March 15 issue of Clinical Cancer Research, a journal of the American Association for Cancer Research.
"The more obese a patient is, the more aggressive the disease," said Massimo Cristofanilli, MD, associate professor of medicine in the Department of Breast Medical Oncology at The University of Texas M.D. Anderson Cancer Center. "We are learning that the fat tissue may increase inflammation that leads to more aggressive disease."
Cristofanilli and colleagues observed 606 women with locally advanced breast cancer. These women were classified by body mass index into the following three groups: normal/underweight (24.9 or below), overweight (at least 25 but less than 30) or obese (more than 30). Body mass index is calculated by dividing a person's weight by their height.
Girls with attention deficit hyperactivity disorder stand a substantially greater risk of developing eating disorders in adolescence than girls without ADHD, a new study has found.
"Adolescent girls with ADHD frequently develop body-image dissatisfaction and may go through repeating cycles of binge eating and purging behaviors that are common in bulimia nervosa," said University of Virginia psychologist Amori Yee Mikami, who led the study.
