Phys.org / Hairy feet, red eyes: Salish Sea reveals two sea spider species new to science
If you're swimming in the Salish Sea late at night and feel a skittering along your calves, tiny hairy feet tip-tapping their way higher and higher toward your face, don't worry—it's probably just the stuff of nightmares: ...
Phys.org / Bee-made propolis boosts an antifungal drug against yeast pathogens in lab tests
Propolis may not only inhibit the growth of certain fungi but also affect the activity of drugs used to treat fungal infections. Researchers have investigated how an ethanolic extract of Polish propolis interacts with various ...
Phys.org / Why a healthy seafloor matters for the Earth system
The seafloor is more than just the ground beneath the sea. Two-thirds of Earth's surface is covered by oceans, which have an average depth of almost 4 kilometers (2.5 miles). For a long time, the seafloor's remoteness protected ...
Phys.org / How social brains allow animal groups to escape danger
Social behavior is found across the tree of life, with animals of all types benefiting from living in a group environment. Large bird flocks and fish schools coordinate their actions by sharing information among individuals. ...
Phys.org / Silicon solar cells could cut satellite power costs by up to 90%
Switching to modern silicon solar cells could cut the cost of powering satellites by as much as 90% based on beginning-of-life (BOL) performance, according to a review led by the University of Surrey. The switch to silicon ...
Phys.org / Central surface density of dark matter agrees with the prediction of a new theory of gravity
A researcher from Sejong University has used a new theory of gravity proposed by Erik Verlinde to predict the observed central surface density of dark matter. The study was published in Physics of the Dark Universe on Sept. ...
Phys.org / Currents in an Arctic sea accelerate the sinking of carbon-carrying phytoplankton
Tiny plantlike organisms called phytoplankton that form the base of marine food webs topped by orcas, whales and sharks usually get eaten or slowly sink to the seafloor, carrying carbon as they go. Across most of the ocean, ...
Phys.org / The Antarctic's only two flowering plants reveal opposing strategies for surviving long-term warming
A team of Chilean and Spanish researchers has published the results of one of the longest-running in-situ warming experiments in maritime Antarctica in the journal Physiologia Plantarum. The experiment exposed the Antarctic ...
Phys.org / Buy, wear, return: Retail fraud and abuse explored in new study
New research reveals retailers are losing money through two kinds of problematic returns: deliberate fraud and opportunistic abuse of generous return policies.
Phys.org / Heat waves on land start earlier and develop faster, global analysis reveals
Heat waves over land worldwide are beginning earlier, ending later and occurring over longer seasons, while the first heat wave of the season has recently shifted toward faster onset, according to a new study published in ...
Phys.org / AI scans 4.6 million compounds in hours to predict hydrogen positions in drug-like molecules
New York University researchers have trained an AI model to learn chemical patterns associated with stability in drug-like molecules and accurately predict where their hydrogen atoms should be positioned.
Phys.org / Snapshots reveal key molecular machine in tropical parasites at near-atomic resolution
A study conducted by the University of Liège and Rockefeller University reveals, with near-atomic precision, the three-dimensional structure and function of a gigantic molecular machine essential to the survival of trypanosomatid ...
