| New research pinpoints 'blue corridors' for highly migratory fish Posted: 09 May 2022 04:15 PM PDT New research has pinpointed four high-traffic areas in the Pacific Ocean that should be considered of high priority if conservation efforts focused on large pelagic fishes such as tuna, blue marlin and swordfish are to be successful. |
| Crystal study may resolve DNA mystery Posted: 09 May 2022 02:10 PM PDT Bioscientists have uncovered a tiny detail that could help us understand how DNA replicates with such astounding accuracy. |
| More difficult than expected for glaciers to recover from climate warming Posted: 09 May 2022 01:28 PM PDT Ice shelves are floating extensions of glaciers. If Greenland's second largest ice shelf breaks up, it may not recover unless Earth's future climate cools considerably. |
| Are new carbon sinks appearing in the Arctic? Posted: 09 May 2022 01:28 PM PDT Global warming can result in the spread of peatland vegetation in the Arctic. An international research group has discovered signs of 'proto-peat', which may be the beginning of new peatlands. |
| How do water mold spores swim? Posted: 09 May 2022 01:28 PM PDT Oomycetes, also known as water moulds, are pathogenic microorganisms that resemble fungi and are responsible for a group of diseases affecting several plant species. To reach and infect plants, the spores swim to their target. Physicists and biologists have now precisely measured the movement of each flagellum while a zoospore follows a linear trajectory and when it is turning. |
| Newly discovered lake may hold secret to Antarctic ice sheet's rise and fall Posted: 09 May 2022 01:28 PM PDT Scientists investigating the underside of the world's largest ice sheet in East Antarctica have discovered a city-size lake whose sediments might answer questions about what Antarctica was like before it froze, how climate change has affected it over its history, and how the ice sheet might behave as the world warms. |
| Ice-capped volcanoes slower to erupt, study finds Posted: 09 May 2022 01:24 PM PDT The Westdahl Peak volcano in Alaska last erupted in 1992, and continued expansion hints at another eruption soon. Experts previously forecasted the next blast to occur by 2010, but the volcano -- located under about 1 kilometer of glacial ice -- has yet to erupt again. Using the Westdahl Peak volcano as inspiration, a new volcanic modeling study examined how glaciers affect the stability and short-term eruption cycles of high-latitude volcanic systems -- some of which exist along major air transportation routes. |
| Posted: 09 May 2022 01:24 PM PDT In June 2019, a magnitude 4.0 earthquake occurred beneath Lake Erie just off the shoreline of Ohio, about 20 miles northeast of Cleveland. |
| Nonlethal parasites reduce how much their wild hosts eat, leading to ecosystem effects Posted: 09 May 2022 01:23 PM PDT Pervasive parasitic infections reduce herbivory rates and can therefore trigger trophic cascades that impact plant communities, according to new research. This work helps fill a recognized knowledge gap regarding the ecological consequences of parasitic infections in natural ecosystems. |
| Quantifying cognitive decline in dogs could help humans with Alzheimer's disease Posted: 09 May 2022 12:07 PM PDT Researchers have found that a suite of complimentary tests can quantify changes in dogs suspected of suffering from cognitive decline. The approach could not only aid owners in managing their elderly canine's care, but could also serve as a model for evaluating cognitive decline progression in -- and treatments for -- humans with Alzheimer's disease. |
| Spider can hide underwater for 30 minutes Posted: 09 May 2022 10:26 AM PDT A tropical spider species uses a 'film' of air to hide underwater from predators for as long as 30 minutes, according to new research. |
| Confirmed: Atmospheric helium levels are rising Posted: 09 May 2022 08:21 AM PDT Scientists used an unprecedented technique to detect that levels of helium are rising in the atmosphere, resolving an issue that has lingered among atmospheric chemists for decades. |
| Chronobiologists identify key circadian clock mechanism in cyanobacteria Posted: 09 May 2022 08:20 AM PDT The activation and inactivation mechanisms of a key protein involved in the circadian clock system of cyanobacteria -- an important organism in the evolution of such internal clocks -- have long eluded scientists. But researchers have now identified how the system is driven. |
| A better diet helps beat depression in young men Posted: 09 May 2022 08:20 AM PDT Young men with a poor diet saw a significant improvement in their symptoms of depression when they switched to a healthy Mediterranean diet, a new study shows. |
| New method to synchronize devices on Earth makes use of cosmic rays Posted: 09 May 2022 08:20 AM PDT Various technologies, networks and institutions benefit from or require accurate time keeping to synchronize their activities. Current ways of synchronizing time have some drawbacks that a new proposed method seeks to address. The cosmic time synchronizer works by synchronizing devices around cosmic ray events detected by those devices. This could bring accurate timing abilities to remote sensing stations, or even underwater, places that other methods cannot serve. Early tests show promise, but the real challenge may lie in the adoption of this new technique. |
| Failed eruptions are at the origin of copper deposits Posted: 09 May 2022 08:20 AM PDT Copper is one of the most widely used metals on the planet today due to its electrical and thermal conduction properties. The greatest natural resources of this metal are the so-called 'porphyry' deposits that come from magmas deep in the Earth. In recent research, scientists demonstrate that these deposits are largely produced by mechanisms similar to those causing large volcanic eruptions. At a time when current copper resources are dwindling and this metal plays a key role in the energy transition, this discovery opens up new avenues for the development of tools to find new deposits. |
| These bats deter predators by buzzing like hornets Posted: 09 May 2022 08:20 AM PDT In Batesian mimicry, a harmless species imitates a more dangerous one in an evolutionary 'ruse' that affords the mimic protection from would-be predators. Now, researchers have discovered the first case of acoustic Batesian mimicry in mammals and one of very few documented in any species: greater mouse-eared bats imitate the buzzing sound of a stinging insect to discourage predatory owls from eating them. |
| Getting sticky with it: Phospholipid found to play a key role in epithelial cell adhesion Posted: 09 May 2022 07:09 AM PDT Cells have certain proteins that help them adhere to each other while covering body surfaces and organs. Loss of these identifying proteins could result in cellular progression towards cancer and, subsequently, metastasis. However, lipids may play a role in maintaining cellular identity as well. Scientists have now identified the role of PIP2, a phospholipid, in maintaining epithelial cell-cell adhesion and cellular identity. Their findings will help develop strategies aimed at suppressing metastasis. |
| Food insecurity risk related to diabetes later in life Posted: 09 May 2022 07:09 AM PDT Young adults who were at risk of food insecurity had increased incidence of diabetes 10 years later, according to a new study. While previous research has associated food insecurity with a range of health issues including diabetes, obesity and hypertension, this study showed a connection over time, suggesting a causal relationship. Researchers analyzed data on nearly 4,000 people from the National Longitudinal Study of Adolescent to Adult Health. They found that adults ages 24-32 who said they'd been worried about food running out in the last year showed greater incidence of diabetes, either through blood glucose tests or self-reports, at ages 32-42, compared to those who did not report food insecurity risk. |
| Why science doesn't help sell chocolate chip cookies Posted: 09 May 2022 07:09 AM PDT People don't want science anywhere near their delicious chocolate chip cookies. But they're happy to have science create body wash that fights odor-causing bacteria. |
| Researchers identify rare genetic markers of drug-resistant tuberculosis Posted: 09 May 2022 07:09 AM PDT Researchers have identified rare genetic markers in M. tuberculosis that could improve early detection of drug-resistant strains of the disease, helping prevent their spread. |
| Future super cyclones would expose many in most vulnerable locations to extreme flooding Posted: 09 May 2022 07:08 AM PDT A new study has revealed super cyclones, the most intense form of tropical storm, are likely to have a much more devastating impact on people in South Asia in future years. |
