La Jolla, Calif., 22, 2015 - A new drug discovered by scientists at Sanford Burnham Prebys Medical Discovery Institute (SBP) may show promise for treating skin cancers that are resistant or unresponsive to today's leading therapies.

In the United States, 5 million people are treated annually for skin cancer, and 9,000 people die from the deadliest form--melanoma--according to the US Department of Health and Human Services.

OAK BROOK, Ill. - Additional breast cancers found with MRI are sometimes larger and potentially more aggressive than those found on mammography, according to a study published online in the journal Radiology. Researchers said that in some cases MRI findings of additional cancers not seen on mammography may necessitate a change in treatment.

Researchers at a breast cancer prevention clinic in Manchester, UK, have observed an increased uptake of preventative double mastectomies since May 2013, when Angelina Jolie announced that she had undergone the procedure.

Human nature's dark side helped us spread across the world

New research by an archaeologist at the University of York suggests that betrayals of trust were the missing link in understanding the rapid spread of our own species around the world.

Dr Penny Spikins, of the University's Department of Archaeology, says that the speed and character of human dispersals changed significantly around 100,000 years ago.

Weekends are associated with a higher rate of complications for births in hospitals in England, a study has found.

Researchers at Imperial College London looked at over 1.3 million births that took place in NHS services in England between 1 April 2010 and 31 March 2012.

Babies born in English NHS hospitals at the weekend have a slightly greater risk of death within the first seven days, compared with those born during the week, finds a study in The BMJ today.

The results also suggest increases in the rates of other complications for both mothers admitted and babies born at weekends.

The researchers estimate that around 770 newborn deaths and 470 maternal infections per year above what might be expected if performance was consistent across women admitted, and babies born, on different days of the week.

One of the wonders of evolutionary innovation in animals is the turtle shell, which differs from any other reptilian defense adaptation, giving up teeth or venom in exchange for an impenetrable shield.

Now, corresponding author and Medical University of Vienna professor Leopold Eckhart and colleagues, in a study published in the advanced online edition of Molecular Biology and Evolution, performed the first comprehensive study of the genes that control the hard cutaneous layers of the shell in the North American painted turtle and other turtles.

Researchers at The Tisch Cancer Institute at the Icahn School of Medicine at Mount Sinai have discovered a key mechanism by which radiation treatment (radiotherapy) fails to completely destroy tumors. And, in the journal Nature Immunology, they offer a novel solution to promote successful radiotherapy for the millions of cancer patients who are treated with it.

Humans have a remarkable ability to synchronize to complex, temporally structured acoustic signals, an ability which is believed to underlie social coordination and may be a precursor to speech. This ability takes years to develop. Although infants move to periodic rhythmic stimuli, children do not synchronize movements to frequency or tempo until the age of 8 or 9. Synchrony in young children is facilitated by social interaction, and promotes prosocial behavior in both children and adults.

In an important step toward creating a practical underwater glue, researchers at UC Santa Barbara have designed a synthetic material that combines the key functionalities of interfacial mussel foot proteins, creating a single, low-molecular-weight, one-component adhesive.

Their findings appear in the journal Nature Communications.

With currently projected funding, countries around the world are unlikely to achieve the Joint United Nations Programme on HIV/AIDS 90-90-90 treatment target (which includes 90% of people diagnosed as living with HIV being treated with anti-retroviral therapy (ART) by 2020), according to a modeling study publishing this week in PLOS Medicine.

Montreal, November 24, 2015 -- As world leaders prepare to gather in France for the 2015 United Nations Conference on Climate Change next week, global warming -- and how to stop it -- is a hot topic.

To limit climate change, experts say that we need to reach carbon neutrality by the end of this century at the latest. To achieve that goal, our dependence on fossil fuels must be reversed. But what energy source will take its place? Researchers from Concordia University in Montreal just might have the answer: algae.

Toronto - The temptation is always there: include every last bit of income you earned last year on your tax return -- or not?

New research has found that we're more likely to do the right thing in situations of moral conflict when it requires little to no effort. If income information is automatically entered into our tax return, we may be less likely to alter it to something that is incorrect once it's there.

Male fruit flies could find their chances of fathering offspring radically reduced if they are last in the queue to mate with promiscuous females before winter arrives, according to new University of Liverpool research.

Usually, when female flies mate with multiple males, the last male fathers most of the offspring, with several other males fathering the rest. However, scientists have found that the outcome of this 'sperm competition' reverses when mating takes place prior to winter hibernation, with only the first male fathering any offspring.

Don't have room for dessert? The bacteria in your gut may be telling you something. Twenty minutes after a meal, gut microbes produce proteins that can suppress food intake in animals, reports a study published November 24 in Cell Metabolism. The researchers also show how these proteins injected into mice and rats act on the brain reducing appetite, suggesting that gut bacteria may help control when and how much we eat.
