By now, the wearying trope of internet outrage is a global touchstone, especially when it comes to "angry young men."
Cambridge, MA - The universe is 13.8 billion years old, while our planet formed just 4.5 billion years ago. Some scientists think this time gap means that life on other planets could be billions of years older than ours. However, new theoretical work suggests that present-day life is actually premature from a cosmic perspective.
House dust differences between Amish and Hutterite communities affect immune development and asthma risk, according to a study co-authored by UA Health Sciences researcher Dr. Donata Vercelli.
Humans have evolved a disproportionately large brain as a result of sizing each other up in large cooperative social groups, researchers have proposed.

Wildlife-friendly farming schemes can help boost the abundance of many UK moth species, a new study by the University of Liverpool has found.
Hubble has captured the glow of new stars in the small, ancient galaxies Pisces A and Pisces B. They should've produced the bulk of their stars long ago, but these dwarf galaxies dwelled for billions of years in the Local Void, a region of the universe sparsely populated with galaxies. Now the tiny galaxies have moved into a region packed with galaxies and intergalactic gas triggering star birth.
A research project has shown that an experimental model of Alzheimer's disease can be successfully treated with a commonly used anti-inflammatory drug.
Dublin, Ireland, Thursday 11th August, 2016 - Scientists have discovered macabre fossil evidence suggesting that 300 million-year-old sharks ate their own young, as fossil poop of adult Orthacanthus sharks contained the tiny teeth of juveniles. These fearsome marine predators used protected coastal lagoons to rear their babies, but it seems they also resorted to cannibalising them when other food sources became scarce.
Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to 2 billion years of its early history, according to computer modeling of the planet's ancient climate by scientists at NASA's Goddard Institute for Space Studies (GISS) in New York.
New findings using data from NASA’s Mars Reconnaissance Orbiter (MRO) show that gullies on modern Mars are most likely not being formed by flowing liquid water. This new evidence will allow researchers to further narrow theories as to the mechanisms behind the formation of gullies on Mars, and help reveal more details about Mars’ recent geologic processes.
With Zika sparking anxiety at the Summer Olympic Games in Brazil, and now being transmitted in Florida through contact with mosquitoes, accurately mapping the distribution of the virus is increasingly urgent.
Health researchers predict that the transmission of dengue could decrease in a future warmer climate, countering previous projections that climate change would cause the potentially lethal virus to spread more easily.
Liquid methane-filled canyons hundreds of meters deep with walls as steep as ski slopes etch the surface of Titan, researchers report in a new study. The new findings provide the first direct evidence of these features on Saturn's largest moon, and could give scientists insights into Titan's origins and similar geologic processes on Earth, according to the study's authors.
A research team, led by Emeritus Professor Kazuhiro Nakaya of Japan's Hokkaido University, analyzed world-first footage captured by public broadcaster NHK in which two goblin sharks separately captured prey on a total of five occasions. The research has unraveled a century-old mystery surrounding how the deep-sea shark utilizes its protruding jaws, among other factors, to feed itself.
Messier 18 was discovered and catalogued in 1764 by Charles Messier -- for whom the Messier Objects are named -- during his search for comet-like objects [1]. It lies within the Milky Way, approximately 4600 light-years away in the constellation of Sagittarius, and consists of many sibling stars loosely bound together in what is known as an open cluster.
Stone objects collected by prehistoric hunters were effective as throwing weapons to hunt animals, research at Leeds Beckett University reveals.
