SNAPSHOT: Hoppy Beer Doesn’t Last Long Before Losing Its Aromatic Flavor

Keep those craft beers cold and don’t hang on to them for too long. That’s the advice from researchers at the Technical University of Munich’s Leibniz-Institute for Food Systems Biology. Scientists there found that cold-stored craft beers lost more than one-third of an important hop aroma after just three months. The beer lost even more flavor when kept at room temperature.

These are generally beers created with a method called “dry-hopping,” where hops is added to young beer late in the

What 88 Bee Genomes and 10 Years of Studying Apples Tell Us About the Future of Pollinators

Stroll through an apple orchard in bloom, and you’ll be surrounded with the buzz of busy bees. But unless the farm manager has rented hives of domesticated honeybees — which are not native to the U.S. — the bees at work will be a highly diverse crew that live in the nearby wild. Big or small, green or striped, shiny or fuzzy, bees come in all types.

While news of bee declines has almost stopped feeling like news, a group of researchers has figured out a new question to ask about these div

Why Humans Lost Their Hair and Became Naked and Sweaty

What makes humans stand out among primates?

We’re naked and unusually sweaty.

Yes, we’re also distinguished by upright walking, big brains and advanced culture. But here I want to focus on our sweaty bare bods.

Millions of years back our ancestors were likely as hairy as chimpanzees and gorillas. Over the course of human evolution, our lineage traded its fur coat for a covering of minuscule body hairs and a few ample patches over the head, armpits and nether region.

Why we became

Thousands Of New Microbiome Species Found Living on the Human Body

In the largest study of its kind, scientists have uncovered thousands of new species inhabiting the human microbiome – -the extensive collection of bacteria, viruses and other micro-organisms that reside all over our bodies, influencing our health. And most of the newly discovered bugs live in and on people from non-Westernized populations. The discovery redefines scientists’ understanding of the human microbiome and could shed light on the increasing incidence of allergies, autoimmune disea

These Bacteria Might Make A Better Mosquito Repellent

In the search for new compounds to fight off mosquitos, researchers have struck pay dirt in an increasingly common location: Soil bacteria.

A pair of molecules produced by a species of insect-infecting bacteria appear to convince mosquitos not to feed on human blood, researchers from the University of Wisconsin-Madison report Wednesday in Science Advances. The find could eventually serve an alternative to chemical insect deterrents like DEET.

The researchers were looking at a genus of
