You’re faced with a dilemma. Inviting yourself when you’re not wanted could come off as intrusive at best, rude at worst. And not inviting yourself will leave you left out and feeling rejected.A new study now should put such anxieties to rest. In such situations, you’re more welcome than you thin ...read more
The Caspian Sea, considered the largest inland body of water on the planet, is shrinking. A new study published in the journal Communications Earth & Environment reports that as global temperatures rise, the Caspian Sea will start to go dry, critically impacting the people and animals that call this place home. Why Is the Caspian Sea Shrinking? According to the new study, the water sources that typically feed the sea are contributing less and less water. So much so that these sources canno ...read more
A jawbone found on the ocean floor near Taiwan provides evidence that the Denisovans — a poorly understood ancestor to modern humans — occupied southeast Asia 100,000 years ago. DNA extracted and analyzed from it has evolutionary implications, because, while contemporary southeast Asians have bits of Denisovan DNA in their genomes, the nearest known Denisovan fossil find, until now, hailed from northeastern Asia, according to a report in the journal Science.“Modern human populations in eas ...read more
If you’ve ever skimmed the ingredient list of your favorite snacks or drinks, you’ve probably stumbled across a string of unfamiliar words — potassium polyphosphate, acesulfame-K, sulphite ammonia caramel, and more — that offer little insight into what you’re actually eating.These food additives are used by manufacturers to boost flavor, texture, appearance, and shelf life. While many are naturally derived and individually tested for safety, recent research suggests that mixing multipl ...read more
Thousands of stone tools discovered in a South African cave reveal that Ice Age humans had developed sophisticated fabrication techniques about 20,000 years ago, according to a report in the Journal of Paleolithic Archaeology.Looking closely at the tools’ chipped blades as well as the larger rocks from which they were formed — what archaeologists call a core — the scientists surmised how the tools were made. That, in turn, reveals much of the makers’ know-how.“When your average person ...read more
