Rescued 'abandoned' penguin chicks survival similar to colony rates

Abandoned penguin chicks that were hand-reared and returned to the wild showed a similar survival rate to their naturally-reared counterparts, according to a study published October 22, 2014 in the open-access journal PLOS ONE by Richard Sherley from University of Cape Town and colleagues.

Camera-traps capture wild chimps' nighttime raiding activities

Wild chimpanzees living in disturbed habitat may use innovative strategies, like foraging crops at night, to coexist with nearby human activities, according to a study published October 22, 2014 in the open-access journal PLOS ONE by Sabrina Krief from Muséum national d'histoire naturelle and colleagues.

Highly effective new anti-cancer drug shows few side effects in mice

Initial studies of the drug, and a precursor called OTS514, found they were effective in killing cancer cells. But they could disrupt the production of new red and white blood cells, causing hematopoietic toxicity such as mild anemia and increasing the risk of infection. At the same time, the drugs increased the production of platelets, which help in blood clotting.

Males of great bustard self-medicate to appear more attractive to females

Males of great bustard consume small doses of poison with a dual purpose: to eliminate intern parasites and, especially, to look healthier and stronger before females, allowing them to achieve a greater reproductive success. A team of researchers from the Spanish National Research Council has now suggested for the first time that this function of self-medication could be a mechanism of sexual selection. The study results are published in the PLOS ONE journal.

Secret wing colors attract female fruit flies

Bright colours appear on a fruit fly's transparent wings against a dark background as a result of light refraction. Researchers from Lund University in Sweden have now demonstrated that females choose a mate based on the males' hidden wing colours.

"Our experiment shows that this newly-discovered trait is important in female choice in fruit flies, and is the first evidence that wing interference patterns have a biological signalling function between the sexes during sexual selection", said Jessica Abbott, a biologist at Lund University.

Thermal receipt paper may be a potentially significant source of BPA

Thermal paper, sometimes used in cash register receipts, may be a potential source of exposure to the hormone disruptor bisphenol-A (BPA), according to a study published October 22, 2014 in the open-access journal PLOS ONE by Annette Hormann from University of Missouri and colleagues.

Results showed that when men and women handled a thermal receipt after using a hand sanitizer, there was a very large amount of BPA transferred from the receipt to the hand, resulting in a rapid increase in blood levels of BPA.

Thermal paper cash register receipts account for high bisphenol A (BPA) levels in humans

COLUMBIA, Mo. – Bisphenol A (BPA) is a chemical that is used in a variety of consumer products, such as water bottles, dental composites and resins used to line metal food and beverage containers, and also is used in thermal paper cash register receipts. Now, research conducted at the University of Missouri is providing the first data that BPA from thermal paper used in cash register receipts accounts for high levels of BPA in humans. Subjects studied showed a rapid increase of BPA in their blood after using a skin care product and then touching a store receipt with BPA.

Cause of aging remains elusive

A report by Chinese researchers in the journal Nature a few months ago was a small sensation: they appeared to have found the cause for why organisms age. An international team of scientists, headed by the University of Bonn, has now refuted a basic assumption of the Nature article. The reasons for aging thus remain elusive.

The Chinese article caused a stir amongst experts worldwide. Using a simple measurement in young nematode worms, the researchers reported they had been able to predict how long they would live .

Research reveals how lymph nodes expand during disease

CANCER RESEARCH UK and UCL scientists have discovered that the same specialised immune cells that patrol the body and spot infections also trigger the expansion of immune organs called lymph nodes, according to a study* published in Nature today (Wednesday).

The immune system defends the body from infections and can also spot and destroy cancer cells. Lymph nodes are at the heart of this response, but until now it has never been explained how they expand during disease.

Fast modeling of cancer mutations

Sequencing the genomes of tumor cells has revealed thousands of genetic mutations linked with cancer. However, sifting through this deluge of information to figure out which of these mutations actually drive cancer growth has proven to be a tedious, time-consuming process.

MIT researchers have now developed a new way to model the effects of these genetic mutations in mice. Their approach, based on the genome-editing technique known as CRISPR, is much faster than existing strategies, which require genetically engineering mice that carry the cancerous mutations.

Drones help show how environmental changes affect the spread of infectious diseases

Unmanned aerial vehicles, or drones, can collect detailed information in real time at relatively low cost for ecological research. In a new Opinion piece published in the Cell Press journal Trends in Parasitology, experts demonstrate that drones can be used to understand how environmental factors influence the spread of infectious diseases.

When heart cancer hides in the brain

It was fortunate for the middle-aged woman that she presented her symptoms at the European Institute of Oncology (IEO), where doctors had seen another strange case just two years before.

The 59-year-old woman had complained of chest pain and shortness of breath. A biopsy revealed that she had an unusual type of "heart cancer" called cardiac lymphoma.

But a week after receiving treatment, the patient developed a headache and her motor skills began to deteriorate.

Strangely, in 2011, a similar case had presented at the IEO.

Quality of biopsy directly linked to survival in bladder cancer patients

UCLA researchers have shown for the first time that the quality of diagnostic staging using biopsy in patients with bladder cancer is directly linked with survival, meaning those that don't get optimal biopsies are more likely to die from their disease.

How people view their own weight influences bariatric surgery success

Negative feelings about one's own weight, known as internalized weight bias, influence the success people have after undergoing weight loss surgery, according to research appearing in the journal Obesity Surgery, published by Springer. The study, from the Geisinger Health System in the US, is considered the first and only study to examine internalized weight bias in relation to post-surgical weight loss success in adults.

Some scientists share better than others

EAST LANSING, Mich. — Some scientists share better than others. While astronomers and geneticists embrace the concept, the culture of ecology still has a ways to go.

Research by Michigan State University, published in the current issue of Bioscience, explores the paradox that although ecologists share findings via scientific journals, they do not share the data on which the studies are built, said Patricia Soranno, MSU fisheries and wildlife professor and co-author of the paper.
