Increased Parental Mortality After Death Of A Child (p 363)
Danish authors of a study in this week's issue of THE LANCET provide strong evidence for the first time that experiencing the death of a child increases the mortality rate of parents-with mothers being far more likely to die early than fathers.    There has been no clear evidence to... view more (2003-01-29)

Genetic and environmental hormonal response to stress in children depends on family context
A study conducted on 346 19-month-old twins by an international team led by Université Laval professor of psychology Michel Boivin reveals that the genetic and environmental bases of hormonal response to stress depend on the context in which a child grows up.   view more (2008-02-21)

Stress Will Not Bring Back Breast Cancer
Violence, bereavement, debt and other stressful experiences do not increase the chances of breast cancer returning in a woman who has been treated for the disease.

An experimental drug that attacks cancer in an entirely new way has shown promise in treating advanced melanoma, delaying progression of the disease and prolonging the lives of patients.   view more (2007-09-27)

Brain stress system presents possible treatment
A brain circuit that underlies feelings of stress and anxiety shows promise as a new therapeutic target for alcoholism, according to new studies by researchers at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH).   view more (2008-02-27)

Heat stress influences low conception of dairy herds
Reproductive efficiency has suffered a dramatic decrease since the mid 1980s despite rapid worldwide progress in genetics and management of high producing dairy herds.   view more (2007-09-07)

Black tea soothes away stress
Daily cups of tea can help you recover more quickly from the stresses of everyday life, according to a new study by UCL (University College London) researchers. New scientific evidence shows that black tea has an effect on stress hormone levels in the body.   view more (2006-10-05)

Agent orange chemical, dioxin, attacks the mitochondria to cause cancer, says Penn research team
Researchers with the University of Pennsylvania School of Veterinary Medicine have demonstrated the process by which the cancer-causing chemical dioxin attacks the cellular machinery, disrupts normal cellular function and ultimately promotes tumor progression.   view more (2007-12-18)

An irregular heartbeat makes exercise deadly
The results of a study in mice that was conducted by researchers from Vanderbilt University has provided a potential explanation for why the heartbeat of humans lacking the protein cardiac calsequestrin (CASQ2) is irregular, and potentially fatal, only during exercise and not at other times.   view more (2006-08-25)

A new way to look at lung cancer and tobacco carcinogens
Two types of cancer-causing agents in cigarettes-a nicotine-derived chemical and polycyclic aromatic hydrocarbons (PAHs) are the main culprits in lung cancer. Exposure to tobacco smoke - both mainstream and second-hand - is a leading cause of cancer death in the United States.   view more (2008-05-29)

New study shows earthquake shaking triggers aftershocks
A new analysis of earthquake data indicates that aftershocks are triggered by the shaking associated with the mainshock, rather than by the added stress on nearby faults resulting from rearrangement of the Earth's crust.   view more (2006-06-08)

New prion protein discovered by Canadian scientists may offer insight into mad cow disease
Scientists have discovered a new protein that may offer fresh insights into brain function in mad cow disease. "Our team has defined a second prion protein called 'Shadoo', that exists in addition to the well-known prion protein called 'PrP' " said Professor David Westaway, director of... view more (2007-08-17)

Stress affects older adults more than young adults
Life can be stressful, whether you're an individual watching the stock market crash or a commuter stuck in traffic. A new study, forthcoming in the journal Psychological Science, examines how stress affects decision-making and finds that older adults alter their behavior more than young adults when... view more (2008-10-28)

Exercise reduces risk of heart disease in postmenopausal women
Aerobic exercise significantly decreased the chemical imbalances that can lead to heart disease and stroke in postmenopausal women according to a study in the spring issue of the Journal of Women and Aging.   view more (2008-03-18)

Why have sex? The answer is not as simple as we thought.
Theories abound as to why organisms favour sexual reproduction, but testing these has been notoriously difficult. A common view is that sexual reproduction helps to reduce the effects of damaging mutations within a population. Now researchers from the Rockefeller University have tested this... view more (2003-05-28)

New collaboration between Amersham Biosciences and Affibody increases potential in protein purification
Under the agreement, the two companies will work to develop affinity-based products for use in the production processes for protein-based pharmaceuticals. The development of these products will be based on Affibodies™, a novel class of small, robust affinity proteins designed to bind desired... view more (2002-03-06)

Slightly stressed carp succumb easily to parasite
Researchers from Wageningen have discovered that slightly stressed carp are much more susceptible to parasites than unstressed carp. All of the laboratory carp which were taken out of the water for one minute a day, died from parasitic attack. Only 40% of the carp who did not undergo the light... view more (2002-09-11)

Environmental enrichment can reduce cocaine use, researchers find
Simple environmental enrichment and increased social stress can both affect the level of individual drug use, according to new monkey research at Wake Forest University School of Medicine.   view more (2008-04-07)

New 'molecular switch' protein protects the heart from major cardiovascular damage
It's just one little amino acid, but it makes all the difference in protecting the heart from the harmful effects of heart attack and cardiac failure. Researchers from the University of Michigan Medical School suggest this amino acid, called histidine, could be the key to a new therapy for... view more (2006-01-23)

Minimally invasive device shows promise in treating female urinary incontinence
A minimally invasive device for treating recurrent stress urinary incontinence in women has been shown to be safe and effective in early clinical trials and is now under review by the U.S. Food and Drug Administration (FDA).   view more (2007-05-23)

Making sense of the human genome: researchers characterize a crucial family of signaling proteins in the human genome
In this month's Genome Biology, Mitch Kostich and colleagues from the Schering-Plough Research Institute (NJ, USA) have identified and mapped an important group of molecules known as protein kinases. These molecules are central to the communication of information both within and between cells, in a... view more (2002-08-23)
