Male dragonflies lose their "bling" in hotter climates
A study published the week of July 5 in the Proceedings of the National Academy of Sciences led by Michael Moore at Washington University in St. Louis finds that dragonfly males have consistently evolved less breeding coloration in regions with hotte.....»»
Record electron temperatures for a small-scale, sheared-flow-stabilized Z-pinch fusion device achieved
In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, roughly the temperature.....»»
Advances in understanding the evolution of stomach loss in agastric fishes
Living beings can evolve to lose biological structures due to potential survival benefits from such losses. For example, certain groups of ray-finned fishes show such regressive evolution—medakas, minnows, puffera, and wrasses do not have a stomach.....»»
Planet sees 10 straight months of record-breaking heat
Californians have had weekend after weekend of cool, stormy weather and the Sierra Nevada has been blessed with a healthy snowpack. But the reality is that even the last few months have been more than 2 degrees hotter than average......»»
It’s cutting calories—not intermittent fasting—that drops weight, study suggests
The study is small and imperfect but offers more data on how time-restricted diets work. Enlarge (credit: Getty | David Jennings) Intermittent fasting, aka time-restricted eating, can help people lose weight—but the r.....»»
Wild turkey numbers are falling in some parts of the US—the main reason may be habitat loss
Birdsong is a welcome sign of spring, but robins and cardinals aren't the only birds showing off for breeding season. In many parts of North America, you're likely to encounter male wild turkeys, puffed up like beach balls and with their tails fanned.....»»
On-demand nutrient production system for long-duration space missions
When astronauts embark on long space missions, they'll need to grow their own food because pre-packaged meals from Earth lose their nutritional value over time. The BioNutrients project at Ames Research Center's Space Biosciences Division has solved.....»»
Exploring why young women in Australia are reluctant to enter politics
Despite growing momentum to increase female representation in Australia's national parliament, it continues to be a male dominated domain. New research from Monash University explores why young women still feel reluctant to become a member of the nat.....»»
Researchers find babbling by zebra finch chicks is important step to memorizing songs
When babies learn to talk or birds learn to sing, the same principle applies: listen and then imitate. This is how the first babble becomes the first word or vocalization. Male zebra finch chicks initially memorize the song of an adult bird. Later, t.....»»
Older male blue tits out-compete young males when it comes to extra-marital breeding
Young male blue tits are less successful in fathering offspring outside their breeding pair, not because of a lack of experience, but because they are outcompeted by older males, Bart Kempenaers and colleagues from the Max Planck Institute for Biolog.....»»
How to keep Earth from being cooked by the ever-hotter Sun
Here are two options for future humans to keep us in the habitable zone. I’d wager a guess that we are, as a species, rather fond of our home planet (our wanton carbon emissions notwithstanding). But the ugly truth is that the Eart.....»»
Bonobos are more aggressive than previously thought, study shows
Chimpanzees and bonobos are often thought to reflect two different sides of human nature—the conflict-ready chimpanzee versus the peaceful bonobo—but a new study published in Current Biology shows that, within their own communities, male bonobos.....»»
The heat is on: What we know about why ocean temperatures keep smashing records
Over the last year, our oceans have been hotter than any time ever recorded. Our instrumental record covers the last 150 years. But based on proxy observations, we can say our oceans are now hotter than well before the rise of human civilization, ver.....»»
Wind energy and bat conservation: Scientists call for the global application of measures to reduce fatalities
The construction of wind turbines as a cornerstone for the production of climate-friendly electricity is rapidly increasing all over the world—and everywhere this results in major challenges for bats, which die directly at the turbines or lose valu.....»»
Understanding the northward movement of the subtropical westerly jet in changing climates
The subtropical westerly jet is a high-altitude, fast-moving air current that flows from west to east in the subtropical region of the Earth's atmosphere. It's an important part of atmospheric circulation, influencing weather patterns and climate con.....»»
Do opponents" race, gender, and party impact US congressional fundraising?
Donations for a political candidate can be motivated by support for that candidate or by opposition to the candidate's opponent. New research published in Social Science Quarterly found that female Democrats and non-white male Democrats in the United.....»»
Atmospheric scientists link Arctic sea loss ice to strong El Niño events
El Niño, a climate pattern where warm waters in the eastern Pacific fuel hotter weather, is finally beginning to wane after bringing a long stretch of record heat and heavy precipitation across the world since last summer......»»
Mustang Mach-E sales underscore pricing issue
Sales data reveals customers are willing to make the switch to EVs at the right price, a challenge for automakers such as Ford that lose thousands on each one they sell......»»
Study says since 1979 climate change has made heat waves last longer, spike hotter, hurt more people
Climate change is making giant heat waves crawl slower across the globe and they are baking more people for a longer time with higher temperatures over larger areas, a new study finds......»»
Quantum computing just got hotter: One degree above absolute zero
For decades, the pursuit of quantum computing has struggled with the need for extremely low temperatures, mere fractions of a degree above absolute zero (0 Kelvin or –273.15°C). That's because the quantum phenomena that grant quantum computers the.....»»
Cold stratification impacts germination rates in Vitis species
It is imperative for the success of the grape industry to develop new grape varieties capable of enduring shifting climates and heightened pressures from diseases and insects. The majority of grape cultivars rely on a specific amount of "chilling ho.....»»
