Climate has influenced the distribution patterns of Adélie penguins across Antarctica for millions of years. The geologic record tells us that as glaciers expanded and covered Adélie breeding habitats with ice, penguins in the region abandoned their colonies. When the glaciers melted during warming periods, the Adélie penguins were able to return to their rocky breeding grounds.

While most butterflies feed on nectar from flowers, researchers from the University of Connecticut believe that northern oak hairstreaks feed on non-nectar sources such as oak galls and honeydew from aphids and other insects.
In addition, this "rare" butterfly may not be so rare after all. The researchers believe that the perceived rarity of the northern oak hairstreak (Satyrium favonius ontario) may be due to the fact that it lives covertly, hidden from the eyes of butterfly watchers as it feeds and breeds overhead in the leaves and branches of the forest canopy.
Research published today in Cell has shown that patient-derived cancer cell lines harbour most of the same genetic changes found in patients' tumours, and could be used to learn how tumours are likely to respond to new drugs, increasing the success rate for developing new personalised cancer treatments.
The process by which a mother's diet during pregnancy can permanently affect her offspring's attributes, such as weight, could be strongly influenced by genetic variation in an unexpected part of the genome, according to research led by Queen Mary University of London (QMUL). The discovery could shed light on why many human genetic studies have previously not been able to fully explain how certain diseases, such as type 2 diabetes and obesity, are inherited.
7 July 2016 - New research shows that patient-derived cancer cell lines harbour most of the same genetic changes found in patients' tumours, and could be used to learn how tumours are likely to respond to new drugs. The findings, published in Cell, will help to increase the success rate for developing new, more personalised cancer treatments.
CINCINNATI -- More women may be smoking and exposed to nicotine during pregnancy than previously thought, according to a new study by researchers from Cincinnati Children's Hospital Medical Center in collaboration with Cradle Cincinnati.
The study reveals a significant gap between the number of local, pregnant mothers who report smoking during pregnancy and the number who test positive for nicotine exposure.
WASHINGTON, DC (July 7, 2016)--Adult lesbian and bisexual women are more likely to be obese than their heterosexual counterparts, but national weight-and-fitness interventions tailored to their needs are lacking. To address this disparity, the U.S. Department of Health and Human Services Office on Women's Health provided funding for the initiative Healthy Weight in Lesbian and Bisexual Women: Striving for a Healthy Community (HWLB), which involved culturally tailored interventions of 12-16 weeks in ten cities across the United States.
UEA research reveals why males outnumber females in bird world
Female birds 'fly the nest' from sparsely populated breeding sites leaving behind small groups of lonely males - according to new research from the University of East Anglia.
Research published today in the Journal of Animal Ecology shows for the first time the causes of skewed sex ratios among small and declining bird populations.
New research has found that developing countries with large carbon sinks and good governance tend to be the main destination for major green donors' climate mitigation funding.
Gay, bisexual and other men who have sex with men continue to have disproportionately high burdens of HIV infection in countries of low, middle and high income around the world, a new study led by the Johns Hopkins Bloomberg School of Public Health suggests.
(PHILADELPHIA) - Over the years, there have been many efforts to use antioxidants to prevent or help treat various diseases and aging. While reactive oxygen species (ROS), can damage and kill cells - these molecules have also been implicated in normal biochemical processes.
In a study published online by JAMA Otolaryngology-Head & Neck Surgery, James A. Bonner, M.D., of the University of Alabama at Birmingham, and colleagues assessed the rates of laryngeal (having to do with the larynx [voice box]) preservation and laryngectomy-free survival in patients receiving the monoclonal antibody cetuximab and radiation therapy (CRT) or radiation therapy alone.
Rapid warming off the western coast of Australia has transformed large stretches of kelp forests into tropical and subtropical marine ecosystems, a new study reports. The results reveal a dramatic transition over a short period of time, where a marine heatwave resulted in the loss of 963 km2 of kelp forests. Since the 1970s, kelp forests along the mid-west section of the Australian coast have experienced steadily increasing ocean temperatures, recently punctuated by three of the warmest summers in the past 215 years.
The Bay Area has long been one of the nation's leading advocates for LGBT equality and community support. Recent studies, however, reveal that one population -- aging lesbian and bisexual women -- are overlooked in the realm of health care and the promotion of healthy lifestyle choices tailored to their needs.
ANN ARBOR, Mich. -- Acupressure helped reduce persistent fatigue in women who had been treated for breast cancer, a new study finds.
Fatigue is one of the most common long-term effects of breast cancer treatment. About a third of women experience moderate to severe fatigue up to 10 years after their treatment ends.
The study, published in JAMA Oncology, found acupressure reduced fatigue by 27 percent to 34 percent over six weeks. Two-thirds of women who did relaxing acupressure, a certain type of the healing method, achieved normal fatigue levels.
