When walked on, these wooden floors harvest enough energy to turn on a lightbulb Posted: 01 Sep 2021 08:37 AM PDT Researchers are tapping into an unexpected energy source right under our feet: wooden floorings. Their nanogenerator enables wood to generate energy from our footfalls. They also improved the wood used in the their nanogenerator with a combination of a silicone coating and embedded nanocrystals, resulting in a device that was 80 times more efficient -- enough to power LED lightbulbs and small electronics.

Prehistoric climate change repeatedly channelled human migrations across Arabia Posted: 01 Sep 2021 08:37 AM PDT Researchers have discovered archaeological sites in the Nefud Desert of Saudi Arabia associated with the remains of ancient lakes formed when periods of increased rainfall transformed the region into grassland. The researchers found that early humans spread into the region during each 'Green Arabia' phase, each bringing a different kind of material culture. The new research establishes northern Arabia as a crucial migration route and a crossroads for early humans.

Choosing personal exercise goals, then tackling them immediately is key to sustatining change Posted: 01 Sep 2021 08:37 AM PDT A new study showed that giving underserved patients at risk of heart disease a choice in their physical activity goal, then having them start right away, resulted in the most change.

Hidden bacterial hairs power nature’s ‘electric grid’ Posted: 01 Sep 2021 08:37 AM PDT A hair-like protein hidden inside bacteria serves as a sort of on-off switch for nature's 'electric grid,' a global web of bacteria-generated nanowires that permeates all oxygen-less soil and deep ocean beds, researchers report. 'The ground beneath our feet, the entire globe, is electrically wired,' said the senior author of the new article.

Early COVID-19 shutdowns helped St. Louis area avoid thousands of deaths Posted: 01 Sep 2021 08:37 AM PDT In March 2020, not long after the first cases of COVID-19 were reported locally, health officials in the city of St. Louis and St. Louis County issued emergency public health orders intended to reduce interactions between people and slow the transmission of the novel respiratory virus. Such action likely saved thousands of lives in the region, according to new research.

Liquid biopsies may aid diagnosis, treatment of bladder, nerve tumors Posted: 01 Sep 2021 07:03 AM PDT Two recent studies describe the potential of liquid biopsies to identify and track tumor growth in two very different cancers: bladder cancer and peripheral nerve tumors. Despite the differences between these cancers and their associated biopsies, the studies demonstrate the possible benefits of this relatively new tool in the fight against cancer.

COVID-19 long-haulers at risk of developing kidney damage, disease Posted: 01 Sep 2021 06:35 AM PDT A study shows that people who have had COVID-19, including those with mild cases, are at an increased risk of developing kidney damage as well as chronic and end-stage kidney diseases. The research emphasizes the importance of kidney care in COVID-19 long-haulers.

Vision: Novel approach reverses amblyopia in animals Posted: 01 Sep 2021 06:35 AM PDT By temporarily suspending retinal activity in the non-amblyopic eye of animal models, neuroscientists restrengthened the visual response in the amblyopic eye, even at ages after the critical period when patch therapy fails.

Confusing mishmash of newborn bathing practices at US hospitals Posted: 01 Sep 2021 06:35 AM PDT A nationwide survey of hospitals has revealed a wide variety of approaches to newborn skincare -- including the timing of the first bath -- that could ultimately have lasting effects on a baby's health and wellbeing.

Do genetics control who our friends are? It seems so with mice Posted: 01 Sep 2021 06:01 AM PDT Have you ever met someone you instantly liked, or at other times, someone who you knew immediately that you did not want to be friends with, although you did not know why? Now, a new study suggests that there may be a biological basis behind this instantaneous compatibility reaction. A team of researchers showed that variations of an enzyme found in a part of the brain that regulates mood and motivation seems to control which mice want to socially interact with other mice -- with the genetically similar mice preferring each other.

Watercooler parts could be a source of organophosphate ester exposure Posted: 01 Sep 2021 06:01 AM PDT Watercoolers have become a staple in homes, offices and schools, but their tanks and parts are made of materials that could release unwanted or potentially harmful compounds into drinking water. In a preliminary study, researchers report that organophosphate esters (OPEs) were found in water dispensed from these systems, but they estimated that daily consumption would be far below the levels associated with health problems.

Antibiotics linked to increased risk of colon cancer Posted: 01 Sep 2021 06:00 AM PDT There is a clear link between taking antibiotics and an increased risk of developing colon cancer within the next five to ten years. This has been confirmed after a study of 40,000 cancer cases. The impact of antibiotics on the intestinal microbiome is thought to lie behind the increased risk of cancer.
