Scholars have discovered evidence of a sixth basic taste. The tongue responds to ammonium chloride, a popular ingredient in some Scandinavian candies. The OTOP1 protein receptor, previously linked to sour taste, is activated by ammonium chloride.  The ability to taste ammonium chloride may have evolved to help organisms avoid harmful substances.

For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and... Read more ›

Some of the thinnest materials known to humankind -- MXene and MBene compounds -- may provide solutions to scientists in their quest to curb the effects of global warming. These substances are only a few atoms thick, making them two-dimensional. Because of their large surface area, the materials have the potential to absorb carbon dioxide molecules from the atmosphere, which could help reduce the harmful effects of climate change by...

Despite decades of decline, a genetic analysis of ruffed grouse reveals that Pennsylvania's state bird harbors more genetic diversity and connectivity than expected. The findings suggest that the iconic game bird could be maintained in persistent numbers if appropriate protections are implemented. Read more ›

The rapid spread of oil palm plantations and associated high use of fertilizer raises concerns about the emission of nitrous oxide, a powerful greenhouse gas. A new study shows that oil palms’ photosynthesis and their response to meteorological and soil conditions play an important but still widely unexplored role in the amount of nitrous oxide produced by oil palm plantations.

Winter is coming—eventually. And while the earth is warming, a new study suggests that the atmosphere is being pushed around in ways that cause long bouts of extreme winter cold or wet in some regions. The study’s authors say they have identified giant meanders in the global jet stream that bring polar air southward, locking in frigid or wet conditions concurrently over much of North America and Europe, often for...

Scientists have found early human migrants left Africa for Eurasia, across the Sinai peninsula and on through Jordan, over 80-thousand years ago. Researchers have proved there was a 'well-watered corridor' which funneled hunter-gatherers through The Levant towards western Asia and northern Arabia via Jordan. Read more ›

Researchers have developed a superhydrophobic surface with a stable plastron that can last for months under water. The team’s general strategy to create long-lasting underwater superhydrophobic surfaces, which repel blood and drastically reduce or prevent the adhesion of bacterial and marine organisms such as barnacles and mussels, opens a range of applications in biomedicine and industry.
