Non-marine animals (amphibians, reptiles, birds and mammals) have apparently experienced at least 10 distinct episodes of intensified extinctions over the past 300 million years. Eight of these extinction events are concurrent with known marine mass extinctions, which previously yielded evidence for an underlying period of 26.4 to 27.3 million years …

Hyperbaric oxygen treatments may induce significant senolytic effects in healthy aging adults, according to new research from Tel Aviv University and the Shamir Medical Center. Hachmo et al. prove that the aging process can be reversed at the basic cellular-molecular level. Aging can be characterized by the progressive loss of …

Jupiter’s icy moon Europa is bombarded by a constant and intense blast of radiation from the gas giant. Different salty compounds on the moon’s surface react differently to the radiation and emit their own unique glimmer. To the naked eye, this glow would look sometimes slightly green, sometimes slightly blue …

In a new study published in the journal Science, an international team of scientists sequenced the genomes of 27 ancient dogs, some of which lived up to nearly 11,000 years ago, across Eurasia. The researchers found that dogs likely arose once from a now-extinct wolf population and that by 11,000 …

Mountain gorillas (Gorilla beringei beringei) live in tight-knit groups, foraging, resting and sleeping together around a core home range and a wider peripheral range. These groups sometimes split permanently, separating gorillas that may have lived together for years and may be closely related. A new study, published in the Journal …

The bright frosts observed in 2015 in the equatorial region of Cthulhu on Pluto are mostly made of methane-rich ice, according to new research. This image, taken by NASA’s New Horizon spacecraft in 2015, shows the Pigafetta Montes mountain range on Pluto; the colorization on the right indicates the concentrations …

In a new study led by the University of Tasmania, an aqueous-based extract of turmeric (Curcuma longa) improved knee pain versus placebo in patients with knee osteoarthritis with local inflammation over 12 weeks; the effect on pain was only moderate; however, it was achieved without any effect on knee structural …

Plant guttation, a fluid from xylem and phloem sap secreted at the margins of leaves from many plant species, serves as a reliable and nutrient-rich food source for many insects, including bees, wasps and flies, according to new research by scientists from Rutgers University, the Instituto Valenciano de Investigaciones Agrarias …
