| Epicenter of major Amazon droughts and fires saw 2.5 billion trees and vines killed Posted: 19 Jul 2021 04:16 PM PDT Triggered by the 2015-16 El Niño, extreme drought and associated mega-wildfires caused the death of around 2.5 billion trees and plants and emitted 495 million tons of CO2 from an area that makes up just 1.2 per cent of the entire Brazilian Amazon rainforest, and 0.01 per cent of the whole biome. |
| Posted: 19 Jul 2021 12:35 PM PDT New research has found marine seismic surveys used in oil and gas exploration are not impacting the abundance or behaviour of commercially valuable fishes in the tropical shelf environment in north-western Australia. |
| How cells control mitochondria Posted: 19 Jul 2021 12:35 PM PDT Researchers discover a signaling protein that controls the assembly of human cellular 'power plants'. |
| DNA duplication linked to the origin and evolution of pine trees and their relatives Posted: 19 Jul 2021 11:34 AM PDT A new study shows that DNA duplication has been vitally important throughout the evolutionary history of gymnosperms, a diverse group of seed plants that includes pines, cypresses, sequoias, ginkgos and cycads. |
| Ocean microbes team up brilliantly to gather food when it's scarce Posted: 19 Jul 2021 11:33 AM PDT What's a hungry marine microbe to do when the pickings are slim? It must capture nutrients - nitrogen, phosphorus, or iron - to survive, yet in vast expanses of the ocean, nutrients are extremely scarce. |
| Remote sensing techniques help treat and manage hollow forests Posted: 19 Jul 2021 08:05 AM PDT New research shows that modelling hyperspectral- and thermal-based plant traits can help in the early detection of Phytophthora-induced symptoms in oak decline. |
| Bats in Tel Aviv enjoy the rich variety and abundance of food the city has to offer Posted: 19 Jul 2021 08:05 AM PDT Researchers have found that when fruit bats forage in the city (Tel Aviv), they are much more exploratory and enjoy the diversity of urban life, visiting a variety of fruit trees every night and tasting as wide a variety of foods as possible. In contrast, rural bats living in Beit Guvrin focus on only one or two fruit trees every night. |
| Novel approach for developing new antibiotics Posted: 19 Jul 2021 08:05 AM PDT Researchers have developed a novel method for producing new antibiotics to combat resistant bacteria. Through an approach that would target bacteria with an antibiotic that is masked by a pro-drug, which the bacteria would themselves remove, the researchers identified a method that would allow for development of new, effective antibiotics that could overcome issues of resistance. |
| Newly introduced butterfly could become widespread in Canada Posted: 19 Jul 2021 08:03 AM PDT This summer, if you see a butterfly with wings that are blue on top with orange spots underneath, you may have crossed paths with a male European Common Blue (or Polyommatus icarus), a newly introduced species in Canada. Could it be a fluke? Probably not, according to a group of researchers who have taken a close look at this captivating blue creature. |
| Novel coronavirus discovered in British bats Posted: 19 Jul 2021 07:31 AM PDT A coronavirus related to the virus that causes Covid-19 in humans has been found in UK horseshoe bats. However, there is no evidence that this novel virus has been transmitted to humans, or that it could in future, unless it mutates. |
| Championing chrononutrition with protein, the morning elixir for muscle growth Posted: 19 Jul 2021 07:31 AM PDT Proteins are essential for body growth and muscle building. However, protein metabolism varies depending on the body's internal biological clock. Therefore, it is important to know how distribution of protein intake over the day affects muscles. Researchers have now found that consumption of proteins at breakfast increases muscle size and function in mice and humans, shedding light on the concept of 'Chrononutrition' that deals with the timing of diets to ensure organ health. |
| Repairing hearts with deadly spider venom: Study Posted: 19 Jul 2021 07:31 AM PDT A potentially life-saving treatment for heart attack victims has been discovered from a very unlikely source - the venom of one of the world's deadliest spiders. A drug candidate developed from a molecule found in the venom of the Fraser Island (K'gari) funnel web spider can prevent damage caused by a heart attack and extend the life of donor hearts used for organ transplants. |
| Unsustainable Arctic shipping risks accelerating damage to the Arctic environment Posted: 19 Jul 2021 07:30 AM PDT The economic and environmental pros and cons of melting Arctic ice creating shorter shipping routes through the polar region are weighed up in ground-breaking research from experts in energy and transport. They conclude that policy makers must properly assess the environmental trade-offs and costs in addition to the commercial benefits and opportunities in Arctic shipping. The authors also want to see more incentives to drive technological developments that will accelerate the uptake of green fuels and technologies. |
| New alpine moth solves 180-year-old mystery Posted: 19 Jul 2021 07:30 AM PDT Butterflies and moths are among the most diverse animal groups. Scientists have found as many as 5,000 species from the Alps alone. Having been a place of intensive research for 250 years, it is considered a sensation if a new species is discovered from the mountain range these days. |
| Deconstructing the infectious machinery of SARS-CoV-2 Posted: 19 Jul 2021 07:30 AM PDT Scientists have published a comprehensive study that -- alongside other recent, complementary studies of coronavirus proteins and genetics -- represents the first step toward developing treatments for COVID-19. |
