DURHAM, N.C. -- Humans aren't alone in their ability to mix perfumes and colognes. Lemurs, too, get more out of their smelly secretions by combining fragrances to create richer, longer-lasting scents, finds a study led by Duke University.

The results appear online April 20 in Royal Society Open Science.

The "perfume" of the ring-tailed lemur could never be confused with Chanel. Male ring-tailed lemurs, our distant primate cousins, produce their distinctive musky odor with help from a pair of glands on their wrists that give off droplets of clear, fast-evaporating fluid, and a second pair of glands on their chests that secrete a brown, foul-smelling paste.

• GPS tool has pinpointed origin of Yiddish speakers

Yiddish is thought to have been invented by Iranian and Ashkenazic Jews as they traded on the Silk Road

Findings provide opposing theory to the view that Yiddish is an old German dialect

The origin of Yiddish, the millennium old language of Ashkenazic Jews, is something which linguists have questioned for decades.

Now, a pioneering tool - the Geographic Population Structure (GPS) - which converts DNA data into its ancestral coordinates, has helped scientists pinpoint that the DNA of Yiddish speakers could have originated from four ancient villages in north-eastern Turkey.

Amsterdam, The Netherlands, 20 April 2016 - A new study being presented today at the 4th Workplace and Indoor Aerosols conference in Barcelona shows, for the first time, that exhaled e-cigarette particles are liquid droplets that evaporate within seconds.
 

The research - a collaboration between Kaunas University of Technology in Lithuania, EMPA Swiss Federal Laboratories for Materials Science and Technology, ETH Zurich the Swiss Federal Institute of Technology and Fontem Ventures - is the first detailed study of its kind conducted to investigate particles in exhaled e-cigarette vapour.
 

Researchers from the University of Liverpool have published a study highlighting the effectiveness of using positive memories and images to help generate positive emotions.

It has been suggested that savouring positive memories can generate positive emotions. Increasing positive emotion can have a range of benefits including reducing attention to and experiences of threat.

The study, supervised by Dr Peter Taylor from the University's Institute of Psychology, Health and Society, investigated individuals' emotional reactions to a guided mental imagery task focussing on positive social memory called the 'social Broad Minded Affective Coping (BMAC)' technique.

Positive affect

1) Motivation (insufficient justification): Throughout the world, there is a ‘new enlightenment.’ Maintaining certain illusions has become so demanding and frustrating that increasingly people simply go for the plain truth because whatever else they say would make little difference in the reception. People witness such and thus find new courage to “call a spade a spade” without apologizing, since an apology in today's mainstream irrational discourse is a mere revealing of weakness that invites further attacks.

Humans may have the most complex breast milk of all mammals. Milk from a human mother contains more than 200 different sugar molecules, way above the average 30-50 found in, for example, mouse or cow milk.

The role of each of these sugars and why their composition changes during breastfeeding is still a scientific puzzle, but it's likely connected to the infant immune system and developing gut microbiome. 

A typical mouse laboratory is kept between 20 and 26 degrees C, but if the mice had it their way, it would be a warm 30 degrees C. While the mice are still considered healthy at cooler temperatures, they expend more energy to maintain their core temperature, and evidence is mounting that even mild chronic cold stress is skewing results in studies of cancer, inflammation, and more. 

HANOVER, N.H. - Virtual and augmented reality have the potential to profoundly impact our society, but the technologies have a few bugs to work out to better simulate realistic visual experience. Now, researchers at Dartmouth College and Stanford University have discovered that "monovision" -- a simple technique borrowed from ophthalmology that dates to the monocle of the Victorian Age - can improve user performance in virtual reality environments.

The International Agency for Research on Cancer, a  United Nations epidemiological group located in France, has been around since the 1960s but only recently got a skeptical look from journalists and the general publi.

Because they declared that sausage is the same risk as cigarette smoking, plutonium, mustard gas and asbestos.

You read that right.

Scientists from Rutgers University and the University of Pennsylvania have identified a biological pathway that could explain why current asthma therapies often prove ineffective.

The discovery has the potential to lead to new treatments for many of the 25 million people in the U.S., including seven million children, who suffer from the chronic condition.

Researchers Reynold A. Panettieri, inaugural director of the clinical and translational science institute at Rutgers, and Edward E. Morrissey, director of the Penn Center for Pulmonary Biology, determined that when certain genes in mice were inactivated, the mice developed an asthma-like condition, exhibiting airway hyper-responsiveness, or AHR, a classic sign of asthma.
