Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
In what they are calling the first study to systematically identify aggressive driving behaviors, a team believe they have measured the changes in driving that occur in an aggressive state. Obviously non-professional aggressive drivers drive faster and make more mistakes than non-aggressive drivers, they put other road users at risk. They also pose a challenge to engineers working on self-driving car technology. UK officials claim that 80 percent of UK road deaths are “predominantly caused by dangerous and reckless drivers.”
Natural events like solar cycles, wildfires, and volcanoes have created dramatic shifts in climate throughout history. Sometimes they even have cultural impact, such as the 'year without a summer' in Europe due to a volcano on the other side of the world, which helped inspire Mary Shelley's "Frankenstein."Less understood have been underwater events. A new analysis of bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, which will mean more accurate climate simulations in the future.
Using data on the structure of galaxy clusters, a recent study made detailed measurements of X-ray emission from galaxy clusters, which revealed the distribution of matter within them. In turn, the data helped the scientists test the prevailing hypothesis of the structure and evolution of the universe, known as Lambda-CDM.
Behavioral data often reveal differences that don't show up on surveys, where answers are free and often aspirational. Data show, for example, that men donate more than women while people who support charities more also have more conservative political stances. The rational is they choose the organizations they want to help, the ones doing work they like. Yet if you get a coffee paid for by the person in front of you at Starbucks, it is likely someone on the left. Charity and generosity are often distinct. A new survey isn't actual behavior but it does lend to the belief that left wing people feel like they are more altruistic.
If you’re a gardener, you may use peat moss - decomposed Sphagnum moss - in soil because it helps retain moisture. Peatlands, wetlands characterized by a thick layer of water-saturated, carbon-rich peat beneath living Sphagnum moss, trees, and other plant life, cover just 3 percent of Earth’s land area but may store a third of all soil carbon. That's made possible in large part by microbes. Two microbial processes in particular — nitrogen fixation and methane oxidation — strike a delicate balance, working together to give Sphagnummosses access to critical nutrients in nutrient-depleted peatlands.
Scholars at Tel Aviv University have recorded and analyzed click-like sounds distinctly emitted by plants. The sounds are similar to the popping of popcorn and emitted at a volume similar to human speech, but frequencies human ears don't detect. The researchers believe plants usually emit sounds when they are under stress, and that each plant and each type of stress is associated with a specific identifiable sound. Though the frequency is too high for human ears, it is in the range detectable by bats, mice, and insects.
Radio telescope observations using
the Atacama Large Millimeter/submillimeter Array (ALMA)
have revealed a cold stream of intergalactic atomic carbon gas feeding star formation in a massive radio galaxy in the young Universe. The findings of
galaxy 4C 41.17
provide observational evidence supporting hypothetical cosmological models and offer new insights into the origins of the cosmic materials that enable galaxy and star formation.
An object over 30 billion times the mass of our Sun has been detected thanks to gravitational lensing - where a foreground galaxy bends the light from a more distant object and magnifies it.
A recent study found that vaccination with two doses of the Pfizer-BioNTech COVID-19 vaccine resulted in immune cell response considerably lower in people with prior SARS-CoV-2 infection than those without. The level of this key immune cell that targets the SARS-CoV-2 spike protein, CD8+ T, was substantially lower in unvaccinated people with COVID-19 than in vaccinated people who had never been infected. People who recover from SARS-CoV-2 infection and then get vaccinated are more protected than people who are unvaccinated and the new paper suggests that the virus damages an important immune-cell response.
In 2014, a new invasive species from Asia was detected in Pennsylvania, but by the time government knows about it, it is too late and spotted lanternflies have since spread to more than 100 counties across 14 states.
Some companies profited during the government lockdowns and then lingering social stigma about being outside the home. Exercise bikes, office furniture, and coffee machines all did well.It will be decades before we know how many have been impacted in ways that were unanticipated. Being at home, for example, should have given more time to exercise, yet it often did the opposite. Despair, prevalent media discussing disaster in real time, and social isolation don't lead to a desire to exercise in some.
Athletes use custom-made insoles because they know a fraction of a second can make the difference between victory and defeat, but to do that specialists must first create a pressure profile of the feet. Athletes walk barefoot over pressure-sensitive mats, where they leave their individual footprints and then orthopedists create customized insoles by hand. The optimization and adjustment takes a lot of time and if you are a wealthy elite, the money is less of a worry but for people with musculoskeletal pain the cost may be out of reach.
