| Open, expressive family life may reduce social deprivation effects among adopted children Posted: 28 May 2021 08:41 AM PDT An environment in which family members support one another and express their feelings can reduce the effects of social deprivation on cognitive ability and development among adopted children, suggests a small study. In contrast, rule-driven households where family members are in conflict may increase an adopted child's chances for cognitive, behavioral and emotional difficulties. |
| Natural gas pipeline density higher overall in more vulnerable US counties Posted: 28 May 2021 08:41 AM PDT An analysis found counties with more socially vulnerable populations had a higher density of natural gas pipelines overall. |

| Reef-building corals and the microscopic algae within their cells evolve together Posted: 28 May 2021 08:41 AM PDT The microscopic algae that live inside and provide nutrients to their reef-building coral hosts may be evolving in tandem with the corals they inhabit. A new study by biologists reveals that genetic differences within a species of these microalgal symbionts correspond to the coral species they inhabit, a discovery that could have implications for the conservation of these endangered corals. |
| Pollen-sized technology protects bees from deadly insecticides Posted: 28 May 2021 08:40 AM PDT New technology provides beekeepers, consumers and farmers with an antidote for deadly pesticides, which kill wild bees and cause beekeepers to lose around a third of their hives every year on average. |
| Japan's hands-off formula in disciplining schoolchildren works. Is it worth a try elsewhere? Posted: 28 May 2021 08:40 AM PDT A look at Japan's mimamoru approach suggests that adults' non-intervention in kids' fights allows children to nurture social and interpersonal skills on their own. Is it worth a try in other countries? |

| DNA-based material with tunable properties Posted: 28 May 2021 08:40 AM PDT While DNA is often idealized as the 'molecule of life', it is also a highly sophisticated polymer that can be used for next-generation materials. Now scientists have started to harness these properties to craft 'topologically tunable' DNA-based complex fluids and soft materials with potential applications in drug delivery and tissue regeneration. |
| Antarctic hotspot: Fin whales favor the waters around Elephant Island Posted: 28 May 2021 08:40 AM PDT During the era of commercial whaling, fin whales were hunted so intensively that only a small percentage of the population in the Southern Hemisphere survived, and even today, marine biologists know little about the life of the world's second-largest whale. |
| Alzheimer's: Blood oxygen levels could explain why memory loss is an early symptom Posted: 28 May 2021 08:40 AM PDT Scientists have recorded blood oxygen levels in the hippocampus and provided experimental proof for why the area, commonly referred to as 'the brain's memory center', is vulnerable to damage and degeneration, a precursor to Alzheimer's disease. |
| Stem cell drugs surprise researchers: Could lead to better drugs in the future Posted: 28 May 2021 08:40 AM PDT Chemotherapy destroys stem cells, which then cannot develop into immune cells and become part of the body's defenses. There are drugs that can remedy this, but previously we did not know exactly how these drugs worked. Now, a new study details their function providing new knowledge that may improve stem cell transplantation and lead to better drug design in the future. |
| Electrons waiting for their turn: New model explains 3D quantum material Posted: 28 May 2021 08:40 AM PDT Scientists have developed a new understanding of how electrons behave in strong magnetic fields. Their results explain measurements of electric currents in three-dimensional materials that signal a quantum Hall effect - a phenomenon thus far only associated with two-dimensional metals. |
| Revenge of the seabed burrowers Posted: 28 May 2021 08:40 AM PDT The ancient burrowers of the seafloor have been getting a bum rap for years. These prehistoric dirt churners -- a wide assortment of worms, trilobites, and other animals that lived in Earth's oceans hundreds of millions of years ago -- are thought to have played a key role in creating the conditions needed for marine life to flourish. Their activities altered the chemical makeup of the sea itself and the amount of oxygen in the oceans, in a process called bioturbation. |
| Detecting skin disorders based on tissue stiffness with a soft sensing device Posted: 28 May 2021 08:40 AM PDT A research team has designed a simple electromechanical device that can be used for deep tissue pathology diagnosis, such as psoriasis, in an automated and non-invasive fashion. The findings will lay a foundation for future applications in the clinical evaluation of skin cancers and other dermatology diseases. |
| 'Good' bacteria show promise for clinical treatment of Crohn's disease, ulcerative colitis Posted: 28 May 2021 08:40 AM PDT A new study shows how a novel consortium of bacteria that live in the digestive tracts of healthy individuals can be used to prevent and treat aggressive colitis in humanized mouse models. |

| Bacterium causing deadly rabbit fever remains virulent for months in cold water, researchers report Posted: 27 May 2021 12:54 PM PDT Disease ecologists have published study results showing how they were able to prove, by replicating environmental conditions in the lab, that Francisella tularensis can persist for months in cold water without any nutrients and remain fully virulent. Their results provide a plausible explanation for how the deadly pathogen, which causes rabbit fever, can overwinter in the environment outside of a host. |
| Changes in how cholesterol breaks down in the body may accelerate progression of dementia Posted: 27 May 2021 12:01 PM PDT The blood-brain barrier is impermeable to cholesterol, yet high blood cholesterol is associated with increased risk of Alzheimer's disease and vascular dementia. However, the underlying mechanisms mediating this relationship are poorly understood.

| Posted: 27 May 2021 11:53 AM PDT New estimates suggest that mass gatherings during an election in the Malaysian state of Sabah directly caused 70 percent of COVID-19 cases detected in Sabah after the election, and indirectly caused 64.4 percent of cases elsewhere in Malaysia. |
| Scientists overhear two atoms chatting Posted: 27 May 2021 11:52 AM PDT How materials behave depends on the interactions between countless atoms. You could see this as a giant group chat in which atoms are continuously exchanging quantum information. Researchers have now been able to intercept a chat between two atoms. |
