In a cutting-edge treatment for Alzheimer's disease, EPFL scientists have developed an implantable capsule that can turn the patient's immune system against the disease.

It's an age-old quandary: Are we born "noble savages" whose best intentions are corrupted by civilization, as the 18th century Swiss philosopher Jean-Jacques Rousseau contended? Or are we fundamentally selfish brutes who need civilization to rein in our base impulses, as the 17th century English philosopher Thomas Hobbes argued?

After exploring the areas of the brain that fuel our empathetic impulses -- and temporarily disabling other regions that oppose those impulses -- two UCLA neuroscientists are coming down on the optimistic side of human nature.

"Our altruism may be more hard-wired than previously thought," said Leonardo Christov-Moore, a postdoctoral fellow at UCLA's Semel Institute of Neuroscience and Human Behavior.

The beautiful title "Siberian unicorn" belongs to Elasmotherium sibiricum - an elasmotherium Siberian rhinoceros, which as previously thought became extinct 350,000 years ago. Nowadays the researchers of Tomsk State University (TSU) figured out that the "unicorn" found his last refuge "only" 29,000 years ago in Kazakhstan. The article, describing the new location of the fossil mammals in the Pavlodar Irtysh, was published in February 2016 in the American Journal of Applied Science.

Research conducted by scientists at the University of York has revealed how recreational ketamine abuse damages the bladder.

In two studies, one of which is published today, the team shows how ketamine present in urine causes damage to the epithelial lining of the bladder, allowing urine to penetrate into underlying tissues which causes inflammation and extreme pain. In some cases this pain can be so extreme that patients need to have their bladder removed (cystectomy).

BOSTON -Approximately one out of five hospitalized adults and one out of three hospitalized children worldwide experience acute kidney injury, the sudden loss of kidney function. Many different factors, including surgery, chemotherapy or shock, can lead to acute kidney injury, but exactly why the kidneys are so vulnerable to these and other stressors has not been well understood.

A recent analysis of popular music reveals that while older age and aging are represented both negatively and positively in music lyrics, negative representations predominate.

Most of the music texts were generated from a young person's perspective and their imaginings of old age.

While negative and positive emotions can influence health and well-being, further research is needed to explore what impact negative texts in popular music may have on older individuals.
