Some of us, when awake in the middle of the night, feel an urge to visit the kitchen. This could explain results of previous studies that have shown a link between short sleep duration and high body mass index (BMI). But a study by Emmanuel Mignot and colleagues suggests that it’s not just the additional snacking opportunities that make short sleepers more likely to be overweight.
Intrigued by the connection between sleep and BMI, and by recent studies showing that sleep depriva

In a world where 842 million people suffer from chronic hunger, insect pests consume 20-30 percent of world food crops. Chemical pesticides are increasingly expensive, ineffective and environmentally aggressive, killing beneficial insects and, when transmitted through the food chain, moving in unwanted directions.
The search for eco-friendly bio-insecticides has focused mainly on developing transgenic crops that express natural protein toxins. The most successful, by far, are crops
At the 2004 ASCB Meeting: Visualizing the Kiss of Death
The very idea threw the Victorian poet Alfred Lord Tennyson into a funk. “Nature, red in tooth and claw,” Tennyson called the nightmarish idea that life was an unending battle to eat or be eaten. If only Tennyson could have seen the latest self-defense videos made by Daniela Malide and others at the National Institutes of Health in Bethesda, MD. Using time-lapse confocal laser scanning microscopy, Malide captured human T-cells
Even the Wizard of Oz couldn’t give the Tin Man a heart but the Johns Hopkins Medical Institution laboratory of John Gearhart has taken another small step on the road toward replenishing damaged cardiac tissue with pre-cursor cardiac cells grown from human embryonic stem cells (ES cells). Gearhart and his colleague, Nicolas Christoforou, here reveal preliminary data demonstrating what they say is a highly reproducible system for deriving cardiac progenitor cells from ES cells through controlled di
Exposure to organochlorine chemicals is linked to reduced bone mineral density among polar bears from East Greenland, according to a study published today in the December issue of the peer-reviewed journal Environmental Health Perspectives (EHP). In the study of 139 polar bear skulls, researchers compared 41 samples collected between 1892 and 1932 with 98 samples collected between 1961 and 2002. Bone mineral density in the skulls collected before 1932—considered “pre-pollution” by the researcher
It is hard to overstate the scale of the humanitarian emergency unfolding in Sudan’s strife-torn Darfur region: by current estimates there are 1.45 million people displaced from their homes across an area the size of France. However, images from space are assisting aid workers as they cope with the crisis.
An ESA-supported consortium called Respond is supplying Earth Observation-derived maps and other geographical information products direct to users in the field including
A surgical procedure being pioneered by University College London (UCL) urologists is enabling men born with a very small penis to acquire an average-sized, functioning penis which not only allows them to urinate normally, but for many, to enjoy a full sex life for the first time.
In a talk to be given on Wednesday 8 December at the European Society for Sexual Medicine conference in London, Dr David Ralph will present the results from recent operations performed at UCL to correct t
Children watching commercials aired during televised sports events may frequently be exposed to violent and unsafe behavior, a study by a Penn State Children’s Hospital physician suggests.
“Our study found that nearly one in five commercials during televised major sporting events depict unsafe or violent behavior,” said Robert F. Tamburro, M.D., associate professor of pediatrics, Penn State Children’s Hospital, Penn State Milton S. Hershey Medical Center. “Studies re
Responses to imatinib found to be durable at 42 months
CHU in Poitiers, France, today announced results of a study showing that newly diagnosed patients with a certain form of leukemia who are treated early with imatinib are more likely to achieve complete cytogenetic responses (the elimination of leukemic cells, a major goal of therapy) and have improved long-term outcomes.

HIV-positive women with low blood platelet counts face significantly higher risk of death compared to women with normal counts, according to a study presented today at the 46th Annual Meeting of the American Society of Hematology.
Findings come from the Women’s Interagency HIV Study, or WIHS, a prospective study of women living with HIV (as well as HIV-negative women for comparison) in six urban areas across the United States. In this portion of the study, researchers looked at 1,
The 10 percent of children with sickle cell disease who are at risk for a stroke need ongoing blood transfusions to reduce their risk, according to a study at 25 sites in North America.
The National Heart, Lung and Blood Institute of the National Institutes of Health, which funded the $11 million study headquartered at the Medical College of Georgia in Augusta, issued a clinical alert to coincide with the Dec. 5 announcement of study findings at the American Society of Hematology
The National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH) has stopped early a clinical trial studying whether children with sickle cell anemia at high risk for stroke could at some point after a minimum of 30 months (range 30-91 months) safely stop receiving the periodic blood transfusions that prevent strokes. The study found a return to high risk of stroke in children who stopped receiving the transfusions. The NHLBI is issuing a clinical alert on the st
Hand preference and language go hand-in-hand, or do they? According to researchers at the Yerkes National Primate Research Center of Emory University, handedness is not associated with the language area of the brain, as has been the accepted scientific thought throughout history. Rather, handedness is associated with the KNOB, the area of the brain known for controlling hand movements in primates and, now, for determining handedness in chimpanzees. The researchers report their groundbreaking find

A University of Minnesota Cancer Center study indicates natural killer cells obtained from a family member and artificially stimulated may provide renewed hope for some patients who have advanced acute myelogenous leukemia (AML), a highly fatal cancer of the bone marrow, that has become resistant to standard treatment with chemotherapy. Natural killer cells are part of the body’s immune system
Two different novel targeted therapies can produce strong responses in patients who have become resistant to Gleevec(tm), the standard therapy for chronic myeloid leukemia (CML), researchers at The University of Texas M. D. Anderson Cancer Center are reporting.
Researchers say the benefits offered by these drugs, BMS-354825 and AMN107, appear to be promising for treatment of relapsed CML and offer an immediate effective option for the minority of patients who do not achieve an op
