Solar panel arrays may help sustain grasslands during drought: Study

Yahoo02-06-2025
The placement of solar panels in Colorado's grasslands could help decrease water stress and increase plant growth by about 20 percent during dry years, a new study has found.
In these semi-arid areas, where grasslands often don't get as much water as they need, the partial shading offered by solar systems can help plants get through harsh summers, according to the study, published in Environmental Research Letters.
The plants also benefit from any additional water that ends up collecting on the panels, the authors noted.
'Even though this solar array was designed to maximize energy generation — not to promote beneficial environmental conditions for the grasses grown beneath — it still provided a more favorable environment during a dry year,' lead author Matthew Sturchio, a postdoctoral researcher at Cornell University, said in a statement.
In more temperate environments, although solar power arrays provide a critical source of renewable energy, they also reduce the availability of sunlight for plant growth. The diminished presence of local vegetation also means a decrease in plant-based carbon storage and the forage available for grazing animals.
But during dry years in semi-arid Colorado, scientists found that grass growth on the east side of panels was in some cases considerably more productive than in adjacent open sites.
In wet and normal years, the positive rate of production was reduced, but the east side of the panels still saw more grass growth than the neighboring control spots.
The scientists suggested maximizing potential gains by adjusting panel arrays to changing environmental conditions — such as repositioning them to provide shade when air temperatures rise or configuring them to let in more light during growing seasons.
'With small changes in array design, configuration and management, we may even realize untapped benefits, particularly those related to water use,' Sturchio said.
Going forward, Sturchio and senior author Alan Knapp, a biology professor at Colorado State University, said they are researching optimal ways to place solar power infrastructure in order to also support grazing livestock or habitat pollinators.
'PV solar arrays may provide a unique opportunity to harvest the sun for electrical energy, reduce greenhouse gas emissions and mitigate the climate change threat of increased water limitation to ecosystem functioning,' the authors concluded.

Common Belief About Left-Handed People Debunked by Psychologists

Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. For decades, popular wisdom has held that left-handed people have a natural edge when it comes to creativity. But, according to new research from Cornell University, the link between left-handedness and artistic talent may be little more than myth. "The data do not support any advantage in creative thinking for lefties," psychologist professor Daniel Casasanto said in a statement. "In fact, there is some evidence that righties are more creative in some laboratory tests, and strong evidence that righties are overrepresented in professions that require the greatest creativity." In their study, Casasanto and colleagues examined more than a century's worth of scientific studies, aiming to resolve a long-standing question: Are left-handed individuals inherently more creative than their right-handed peers? However, the team found little fact to support the stereotype.

Getty Images The widespread belief that left-handers—who make up roughly 10 percent of the population—are more imaginative or artistically gifted has persisted in part due to the brain's structure. Creative thinking, especially divergent thinking—the ability to generate multiple solutions to a problem—is more associated with the brain's right hemisphere, which also controls the left side of the body. In one prior study, for example, participants performed better on divergent thinking tests after squeezing a ball with their left hand, potentially stimulating creativity-supportive brain regions. That gave rise to the idea that left-handers might effectively conduct that experiment every time they use their dominant hand. But it seems the reality is more complex. In their study, Casasanto and colleagues analyzed nearly 1,000 papers published since 1900 that focused on handedness and creativity. Only 17 studies, covering about 50 effect sizes, met the criteria for inclusion due to consistent data reporting and inclusion of both left- and right-handed participants. The results of these studies indicated that handedness made little difference in performance across the most common lab tests of divergent thinking. In some cases, right-handed individuals showed a slight advantage. The researchers also re-examined occupational data from nearly 12,000 Americans across more than 770 professions, categorizing each role based on levels of required creativity. While artists and musicians did show a higher proportion of left-handers, other highly creative fields such as architecture did not. "Left-handers are overrepresented among artists and musicians," the study found, "but not among architects, physicists or other professions commonly perceived as creative." In fact, when ranked by creativity demands, professions such as physics and mathematics—comparable in creativity to fine arts because all fields were measured for originality and inductive reasoning—showed left-handers to be underrepresented. Casasanto said that the myth likely endures due to what he called "left-handed exceptionalism"—the idea that since left-handedness is rare, and how creative genius is rare, one might explain the other. Dr. Mosun, a consultant psychiatrist at Cassiobury Court and a Member of the Royal College of Psychiatrists (MRCPsych), told Newsweek that the myth has taken hold partly because of famous left-handed individuals in the arts like Paul McCartney and Jimi Hendrix. "There has been this almost romantic notion that left-handed people are naturally more artistic or creative," Mosun explained. "Historically, left handedness was seen as rare and associated with difference, which society sometimes interprets as special talent or even genius." But according to Mosun, the persistence of the stereotype reflects a broader tendency to simplify the origins of talent. "In reality, what this new research shows is that left-handed people aren't inherently more creative, but that doesn't take away from their individuality," she added. "It simply reminds us that creativity is influenced by so many factors—environment, education, culture, and also personality—rather than our dominant hand. "Stereotypes like these often emerge because we look for patterns to explain the exceptional, but the truth is always more nuanced."

Scientists Detect Radio Burst From Deepest Space, Then Realize It's Just A Satellite, Then Realize The Satellite Was Signaling From Beyond The Grave

A scientific paper was recently published on Cornell University's arXiv describing a radio burst that lasted for a mere 30 nanoseconds. Maybe that doesn't sound too exciting, except that the signal was thought to come from another galaxy. But then it turned out it was just from a satellite. But then it turned out that the satellite had been dead for decades and couldn't actually produce a transmission like that. So now it's a story about a zombie satellite sending impossible messages from beyond the grave, in space. Interested yet? In June 2024, the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope detected what was thought to be a fast radio burst (FRB). Makes sense, as that was exactly what the telescope was trying to find. From reporting by FRBs remain something of a mystery even 20 years after their discovery, which of course just make scientists want to study them more. So detecting one was pretty great... until the team examining the find realized that the FRB made no sense at all. For one thing, the signal was too short — FRBs typically last micro- or milliseconds, not mere nanoseconds. Yes, those time frames are all incredibly small, but they are orders of magnitude apart. The radio telescope's image of it was also very fuzzy, which, like with a normal camera, indicated that the source was actually very, very close, not in a distant galaxy, where other FRB signals were from. What on Earth (or off it) was going on? Well, the answer turned out to be very boring, right before it got incredibly weird. Read more: These Cars Are Going To Age Terribly Once scientists had worked out the exact origin position of the signal, they realized that it was actually so close to Earth that it might well be a satellite, per New Scientist. They cross-referenced with known orbits, and sure enough, one popped up. Ah, darn, just a satellite then. No big deal — hey wait, is that satellite dead? Yes, and not just dead, but long dead. NASA's Relay 2 was in fact one of the first ever satellites, launched all the way back in 1964 at the dawn of the space age. Along with its sister Relay 1, these were experimental communications satellites intended to map the Van Allen radiation belt, per our friends at Gizmodo. Then in June 1967 (everything in this story happens in June, weird), the transponders failed, and that was the end of that. Except, now it isn't. Apparently the long-dead experimental communications satellite decided to get very experimental with its communications, since it sent out a radio burst all of a sudden. If you're wondering how a dead satellite can do that, you're not alone, because no one knows for sure. In fact, the on-board equipment is not even capable of transmitting a 30 nanosecond pulse. Rising from the grave to send impossible messages? What is this, space Ouija? In their scientific paper, the team theorizes one of two possible explanations, as lays out. First is that an electrostatic discharge (ESD) might have built up, causing a brief spark that caused a radio burst. Think of rubbing your hand along a carpet, then touching something metal. In space, the "carpet" would be ionized gas or plasma, so if Relay 2 passed through some of that, it might have sparked. This has actually been observed before, but again, at much longer timescales than 30 nanoseconds, which might count against this theory. If it does prove to be true, it actually has some practical value. ESDs are known to cause damage to satellites, but they are difficult to detect. Possibly, these scientists have stumbled on a way to detect them, making it easier to diagnose a faulty satellite. The second theory, as if this all couldn't get any better, was that the zombie satellite was actually hit by a teeny tiny micrometeorite traveling at 44,000 mph. This little hypothetical guy would only be a few micrograms, but if it struck Relay 2, it would create a puff of charged plasma, which is what the radio telescope would have detected. Both of these are still just theories, and really, nobody knows for sure. If you think that space necromancers must surely be involved, I wouldn't doubt it. It all just goes to show that space is a vast, weird place, and even our brightest minds are still only just scratching the surface of all it has to tell us. Want more like this?
