It’s hard to know what Neanderthals ate: food preparation, especially when it comes to smaller items like birds, can leave few archaeological traces. But understanding their diets is critical to understanding these incredibly adaptable hominins, who thrived for hundreds of thousands of years … Read more
[ad_1] Peacock butterfly. Credit: Sam England Butterflies and moths collect so much static electricity while in flight, that pollen grains from flowers can be pulled by static electricity across air gaps of several millimeters or centimeters. The finding, published in the Journal of the Royal Society Interface, suggests that this likely increases their efficiency and … Read more
[ad_1] Credit: University of Cambridge Researchers at the University of Cambridge have demonstrated that the plant hormone gibberellin (GA) is essential for the formation and maturation of nitrogen-fixing root nodules in legumes and can also increase nodule size. They identified the specific times and location where GA governs the initiation, growth and function of nodules. … Read more

[ad_1] Credit: Pixabay/CC0 Public Domain Social media is a problem for economists. They don’t know how to value it. It has long been argued that it ought to be in the national accounts as part of gross domestic product. One 2019 study estimated Facebook alone is worth US$40 to US$50 per month for consumers in … Read more
[ad_1] Credit: Pixabay/CC0 Public Domain The identification of a key gene in monotremes has increased our understanding of why the stomachs of platypuses and echidnas are atypically small, non-acidic, and, in the instance of platypuses, lack a pyloric sphincter. Called Nkx3.2, the gene was inactivated in the common ancestor between platypuses and echidnas and this … Read more
