Missing link in pterosaur origins discovered

Nearly nothing is known about the family tree of pterosaurs — iconic reptiles that flew alongside the dinosaurs. These now-extinct beasts appear in the fossil record with already developed wings and senses adapted for flying, with researchers having nary a clue about their immediate evolutionary history. But now, the pterosaur’s family tree has a new […]

Top 10 questions I’d ask an alien from the Galactic Federation

Any science journalist would rejoice at the revelation of aliens on Earth. It would be the story of a lifetime. So it’s not surprising that a former Israeli space official’s claim that a Galactic Federation is known to the U.S. government has made a few headlines and trended on Twitter. Of course, most science journalists […]

Neanderthals buried their dead — ScienceDaily

Was burial of the dead practiced by Neandertals or is it an innovation specific to our species? There are indications in favour of the first hypothesis but some scientists remain sceptical. For the first time in Europe, however, a multi-disciplinary team led by researchers at the CNRS and the Muséum national d’histoire naturelle (France) and […]

When Cyclones and Conflicts Collide

Relationships between extreme weather and subsequent violence can be fiendishly complex to disentangle. But these links are becoming increasingly relevant as weather extremes become more frequent because of climate change. A new project led by two U.S. researchers is tackling one important question: What impact do tropical cyclones have on armed conflict? Cyclones […]

Gifts that make video calls look and feel more glamorous

Whether you want to share a mic or keep it to yourself, you’ll need the right sound equipment. (Andrew Lozovyi/Deposit Photos/) Last year, when the holidays rolled around, we had no idea how important video chatting was about to become. Now, it’s common to spend large chunks of our days and nights gabbing at a […]

Social media messages help reduce meat consumption

Sending direct messages on social media informing people of the negative health and environmental impacts of consuming meat has proven successful at changing eating habits, a new study from Cardiff University has shown. The study showed that sending direct messages twice a day through Facebook Messenger led to a significant reduction in the amount of […]

The dynamics of nitrogen-based fertilizers in the root zone

Credit: CC0 Public Domain Nutrient contamination of groundwater as a result of nitrogen-based fertilizers is a problem in many places in Europe. Calculations by a team of scientists led by the UFZ have shown that over a period of at least four months per year, nitrate can leach into the groundwater and surface water on […]

Dramatic transformation of the Arctic landscape may be permanent

From vanishing sea ice to blistering air temperatures to zombie fires, climate change is reshaping the Arctic. And that transformation may be permanent, researchers said on Tuesday (Dec. 8) at the annual meeting of the American Geophysical Union (AGU). The Arctic has warmed and melted at an alarmingly accelerating pace over the last 15 years, […]

In the past 15 years, climate change has transformed the Arctic

Fifteen years of grading warming’s impact on the Arctic has made one thing abundantly clear: Climate change has drastically altered the Arctic in that short time period. Breaking unfortunate records is “like whack-a-mole,” says Jackie Richter-Menge, a climate scientist at the University of Alaska Fairbanks and an editor of the 2020 Arctic Report Card, released […]
