Climate change could deprive Volta Basin of water needed to boost energy and food production
A new study released today finds that so much water may be lost in the Volta River Basin due to climate change that planned hydroelectric projects to boost energy and food production may only tread water in keeping up with actual demand. Some 24 million people in Ghana, Burkina Faso and four other neighboring countries depend on the Volta River and its tributaries as their principal source of water.

Working the night shift on the moon
There's never a cloudy day on the moon. It's flooded with sunshine 24/7 during its two-week-long daytime, so it makes sense to use solar energy to power future lunar rovers and other devices. But each lunar day is followed by two weeks of lunar night, and that means a long stretch of downtime after the sun sets.
A warmer planetary haven around cool stars, as ice warms rather than cools
(Phys.org) —In a bit of cosmic irony, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. This is due to the interaction of a star's light with ice and snow on the planet's surface.

Yet sex addiction has been blamed for ruining relationships, lives and careers.

The hair of the dog
A surprisingly large number of dogs suffer from hyperadrenocorticism. The symptoms are caused by excessive amounts of hormones – glucocorticoids – in the body. Unfortunately, though, diagnosis of the disease is complicated by the fact that glucocorticoid levels naturally fluctuate and most methods for measuring the concentration of the hormones in the blood provide only a snapshot of the current situation. Recent research at the University of Veterinary Medicine, Vienna has shown that glucocorticoids accumulate in the animals' hair and that analysis of a dog's hair can provide quick and reliable preliminary diagnosis. The results are published in the current issue of the journal Veterinary Dermatology.

Controversy exists over what some mental health experts call "hypersexuality," or sexual "addiction." Namely, is it a mental disorder at all, or something else? It failed to make the cut in the recently updated Diagnostic and Statistical Manual of Mental Disorders, or DSM-5, considered the bible for diagnosing mental disorders. Yet sex addiction has been blamed for ruining relationships, lives and careers.

The system, which was developed by University of Rochester Medical Center (URMC) researchers, could also ultimately be deployed to detect and track breast, kidney, liver, skin and thyroid cancers.
Want kids to eat healthier? Don't tell them, show them
If given the choice between eating a salad loaded with veggies or a burger and fries, most kids—and for that matter, most adults—would likely pick the less healthful option. But instead of telling kids to eat more fruits and vegetables, Iowa State University researchers found the trick may be to convince them visually.

Overnights away from home affect children's attachments, study shows
Babies have an innate biological need to be attached to caregivers, usually their parents. But what happens when babies spend a night or more per week away from a primary caregiver, as increasingly happens in cases where the parents share custody, but do not live together?
The hair of the dog
A surprisingly large number of dogs suffer from hyperadrenocorticism. The symptoms are caused by excessive amounts of hormones – glucocorticoids – in the body. Unfortunately, though, diagnosis of the disease is complicated by the fact that glucocorticoid levels naturally fluctuate and most methods for measuring the concentration of the hormones in the blood provide only a snapshot of the current situation. Recent research at the University of Veterinary Medicine, Vienna has shown that glucocorticoids accumulate in the animals' hair and that analysis of a dog's hair can provide quick and reliable preliminary diagnosis. The results are published in the current issue of the journal Veterinary Dermatology.
Tuberculosis genomes recovered from 200-year old Hungarian mummy
Researchers at the University of Warwick have recovered tuberculosis (TB) genomes from the lung tissue of a 215-year old mummy using a technique known as metagenomics.
Eating eggs is not linked to high cholesterol in adolescents
Although in the late 20th century it was maintained that eating more than two eggs a week could increase cholesterol, in recent years experts have begun to refute this myth. Now, a new study has found that eating more eggs is not associated with higher serum cholesterol in adolescents, regardless of how much physical activity they do.

Alternative target for breast cancer drugs
Scientists have identified higher levels of a receptor protein found on the surface of human breast tumour cells that may serve as a new drug target for the treatment of breast cancer. The results, which are published today in EMBO Molecular Medicine, show that elevated levels of the protein Ret, which is short for "Rearranged during transfection", are associated with a lower likelihood of survival for breast cancer patients in the years following surgery to remove tumours and cancerous tissue.
