Obtaining high status was likely as easy for men in the Tang Dynasty as for men in the modern US, a study suggests. It found that social mobility for men at the time could be compared to that of the 1960s in the US. AdvertisementMen in medieval China could gain high status in society as easily as male Baby Boomers in the US, according to a new study released on Thursday. Women, however, were unlikely to be part of the Chinese bureaucracy, and few would have taken the imperial exam, Hout said. But I wouldn't see a farmer's kid being able to pass the exam," Hout said.

☆ Virgin Atlantic plane will fly from London to New York with 100% Sustainable Aviation Fuel. Experts say it’s not a fix

CNN —For the first time, a transatlantic flight operated by a commercial airline will be powered by 100% Sustainable Aviation Fuel (SAF) — a type of plane fuel that bears the promise of a much lower climate impact than traditional ones. The flight is the latest in a series of recent tests involving 100% SAF. Days earlier, business jet maker Gulfstream completed what it billed as the world’s first transatlantic flight using 100% SAF. Large twin-engine jets have performed flights using 100% SAF on both engines before, but these flights involved military aircraft. “One flight on 100% alternative fuel isn’t going to change the fact that 99.9% of aviation fuel is fossil fuel and there’s no great option for feedstock (raw materials) that can be scaled up sustainably,” she says.

Many countries are working on them — and neither China, Russia, Iran, India or Pakistan have signed a U.S.-initiated pledge to use military AI responsibly. Another AI project at Space Force analyzes radar data to detect imminent adversary missile launches, he said. One urgent challenge, says Jane Pinelis, chief AI engineer at Johns Hopkins University’s Applied Physics Lab and former chief of AI assurance in Martell’s office, is recruiting and retaining the talent needed to test AI tech. Testing and evaluation standards are also immature, a recent National Academy of Sciences report on Air Force AI highlighted.

Every year, researchers in economics are awarded the Nobel Prize, alongside a hefty sum in winnings. All you have to do is bag a Nobel Prize. Franco Modigliani, an MIT professor who nabbed the Nobel in economics in 1985 , got about $225,000 in winnings. But, ultimately, he wanted to spend his winnings according to his own research on people's saving and spending habits. So when he was asked how he'd spend what was, in 2017 dollars, around $1.1 million in winnings, Thaler told reporters : "I will try to spend it as irrationally as possible."

In December last year, after years of trying, the National Ignition Facility, or NIF, at Lawrence Livermore National Laboratory reported that it had finally lived up to its middle name: ignition. For the first time anywhere, a laser-induced burst of fusion produced more energy than that supplied by the incoming lasers. “We’re really excited by the NIF results,” said Kramer Akli, who manages the fusion energy sciences program at the United States Department of Energy. A decade ago, a report by the National Academy of Sciences found much to like in the energy potential of laser fusion but recommended that the United States hold off major investments until ignition was achieved. The sun generates heat and light by jamming — fusing — hydrogen atoms together into helium.

Debates about its efficacy abound, with the United States, Europe and several environmental groups speaking out about the opportunities and risks. Research has been conducted into other potentially less dangerous SRM technologies, including marine cloud brightening, which involves the spraying of seawater from ships to make clouds more reflective. One group of 60 scientists launched a global initiative last year aimed at persuading governments to ban outdoor solar geoengineering experiments. "Once you've committed to it, you've got to keep doing it," said Laura Wilcox, a climate expert at Britain's University of Exeter. "If you stop, then you're going to see all of that warming that you've missed, essentially on climate timescales overnight.

The U.S. researchers found a relationship between soy production and related community exposure to agrochemicals including glyphosate, a widely used weedkiller that some genetically modified soybean seeds are designed to tolerate. "We find a statistically significant increase in pediatric leukemia following expanded local soy production," the PNAS article said, based on Brazilian childhood cancer incidence and disease mortality data spanning 15 years. Specifically, the study found a correlation between soy farming and childhood blood cancers, especially acute lymphoblastic leukemia (ALL), the most common blood cancer in children. There were 123 additional deaths of children under age 10 from 2008 to 2019 from ALL following the expansion of soybean production in Brazil, the researchers found. That number would have been higher were it not for the country's high-quality cancer treatment centers, the researchers said.

Evolution occurs, it holds, when these various configurations are subject to selection for useful functions. "We have well-documented laws that describe such everyday phenomena as forces, motions, gravity, electricity and magnetism and energy," Hazen said. The subsequent generation of stars that formed from the remnants of the prior generation then similarly forged almost 100 more elements. "Imagine a system of atoms or molecules that can exist in countless trillions of different arrangements or configurations," Hazen said. "Only a small fraction of all possible configurations will 'work' - that is, they will have some useful degree of function.

"It's very disturbing," study co-author Matthew Huber of Purdue University in the U.S. state of Indiana told Reuters. It found that around 750 million people could experience one week per year of potentially deadly humid heat if temperatures rise 2 degrees Celsius (3.6 degrees Fahrenheit) above preindustrial levels. At 4C of warming, Hodeidah, Yemen, would see around 300 days per year of potentially unsurvivable humid heat. WET-BULB THRESHOLDTo track such moist heat, scientists use a measurement known as "wet-bulb" temperature. Beyond this, people were likely to succumb to heat stress if they could not find a way to cool down.

CNN —The 2023 Nobel Prize in physics has been awarded to a team of scientists who created a ground-breaking technique using lasers to understand the extremely rapid movements of electrons, which were previously thought impossible to follow. “An attosecond is to one second as one second is to the age of the universe,” the committee explained. Pierre Agostini, Ferenc Krausz and Anne L'Huillier shared this year's physics prize. Rapid movements blur together, making extremely short events impossible to observe. Electrons’ movements in atoms and molecules are so rapid that they are measured in attoseconds.

CNN —Round discs of barren dirt known as “fairy circles” look like rows of polka dots that can spread for miles over the ground. Fairy circles were previously spotted only in the arid lands of Southern Africa’s Namib Desert and the outback of Western Australia. The results showed 263 dryland locations where there were circular patterns similar to fairy circles in Namibia and Australia. Fairy circles’ mysterious originsThe study authors also compiled environmental data where circles were spotted, collecting evidence that might hint at what causes them to form. But the question “What shapes fairy circles?” is complex, and factors that create fairy circles may differ from site to site, the study authors reported.

Small farms with natural landscape features such as shade trees, hedgerows and tracts of intact forest provide a refuge for some tropical bird populations, according to an 18-year study in Costa Rica. For almost two decades, ornithologist James Zook has been collecting detailed records on nearly 430 tropical bird species found on small farms, plantations and undisturbed forests in the country. While birds thrive the most in undisturbed rainforests, Zook said some species usually found in forests can establish populations in “diversified farms” that partially mimic a natural forest environment. “In these diversified farms, you see growth over the long term in bird species with specialized needs,” such as safe and shady nooks to build nests and a variety of food sources, Hendershot said. Three-quarters of the 305 species found in diversified farms showed stable or growing populations over the time of study.

Dark matter, invisible material whose presence is known mainly based on its gravitational effects at a galactic scale, would be a small but crucial ingredient in dark stars. Based on the Webb data, these objects could be either early galaxies or dark stars, Freese said. Conditions in the early universe may have been conducive to formation of dark stars, with high dark matter densities at the locations of star-forming clouds of hydrogen and helium. Freese and two colleagues first proposed the existence of dark stars in 2008, basing the name on the 1960s Grateful Dead song "Dark Star." And then you can learn about the properties of dark matter particles by studying a variety of dark stars of different masses."

What is it that we hear when we hear nothing at all? Or are we just hearing nothing and interpreting that absence as silence? The “Sound of Silence” is a philosophical question that made for one of Simon & Garfunkel’s most enduring songs, but it’s also a subject that can be tested by psychologists. In a paper published Monday in the Proceedings of the National Academy of Sciences, researchers used a series of sonic illusions to show that people perceive silences much as they hear sounds. While the study offers no insight into how our brains might be processing silence, the results suggest that people perceive silence as its own type of “sound,” not just as a gap between noises.

Scientists previously theorized that megalodons were warm-blooded, but the new study is the first to provide concrete evidence to that effect. From this finding, they deduced the megalodon’s average body temperature was about 27 C (80 F). Like modern great white and mako sharks, megalodons were regionally endothermic, which means they had the ability to regulate temperature in certain parts of the body, according to the study. The timing of megalodons’ extinction coincides with the cooling of the Earth’s temperature, the researchers said. But learning more about the ancient shark could still help scientists better understand the threats similar marine animals face today.

The area burned from wildfires in California's northern and central forests increased fivefold between 1971 and 2021, an increase driven largely by human-caused climate change, according to new research published in the Proceedings of the National Academy of Sciences. The 10 largest wildfires in California happened in the last two decades, five of which occurred in 2020 and eight after 2017. Scientists estimate the area burned during an average summer could rise as much as 50% by midcentury as hotter and drier conditions intensify the blazes. The researchers conducted a statistical analysis of temperature and wildfire data for summers in California between 1971 and 2021 and assessed models that showed how the last few decades may have looked without human-caused greenhouse gas emissions. They discovered that burned area increased 172% more than it would have without climate change.

☆ Petermann Glacier in Greenland is melting away with the tide, which could signal faster sea level rise, study finds
▼ + stars: | 2023-05-08 | by ( Brandon Miller | Cnn Meteorologist | ) edition.cnn.com time to read: +2 min

CNN —A major glacier in northwest Greenland is interacting with the ocean tides, scientists reported Monday, resulting in previously unaccounted-for melting and potentially faster sea level rise. This is an important finding: The traditional view among scientists was that the grounding line did not migrate with the tides – and this introduces another major source of melting that could be accelerating sea level rise. Between 2016 and 2022, warmer tidal cycles melted a 670-foot-tall hole in the underside of the glacier along the grounding line — big enough that two Statues of Liberty could be stacked on top of one another inside it. The study raises more concerns for the already worrisome prospect of sea level rise, which threatens coastlines around the world. Greenland’s melting ice is the single largest contributor to sea level rise, according to NASA, which has been accelerating in recent years.
