DeepMind Cracks "Knot" Conjecture That Bedeviled Mathematicians For Decades
The artificial intelligence (AI) program DeepMind has gotten closer to proving a math conjecture that's bedeviled mathematicians for decades and revealed another new conjecture that may unravel how mathematicians understand knots. Live Science report.....»»
NASA study tallies carbon emissions from massive Canadian fires
Stoked by Canada's warmest and driest conditions in decades, extreme forest fires in 2023 released about 640 million metric tons of carbon, NASA scientists have found. That's comparable in magnitude to the annual fossil fuel emissions of a large indu.....»»
DNA replication in early embryos differs from previous assumptions, study shows
A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the experiments published August 28 in Nature show that DNA repl.....»»
Researchers model physics of the pumping technique used to achieve air on a skateboard half-pipe
A team of engineers and mathematicians from ETH Zürich, working with colleagues from The Institute of Statistical Mathematics, and ATR Institute International, both in Japan, has successfully modeled the physics involved when humans pump on skateboa.....»»
Mathematicians debunk GPS assumptions to offer improvements
The summer holidays are ending, which for many concludes with a long drive home and reliance on GPS devices to get safely home. But every now and then, GPS devices can suggest strange directions or get briefly confused about your location. But until.....»»
How a survey of over 2,000 women in the 1920s changed the way Americans thought about female sexuality
American women still have fewer orgasms than men, according to new research that suggests that decades after the sexual revolution, the "orgasm gap" is still very much in effect......»»
Nonprofits with investment income slower to recover from economic downturns, study shows
A recent study evaluates three decades of financial data from nonprofit organizations and finds that while the sector tends to bounce back quickly after periods of economic recession, some organizations bounce back more quickly than others. Specifica.....»»
This bird species was extinct in Europe. Now it"s back, and humans must help it migrate for winter
How do you teach a bird how, and where, to fly? The distinctive Northern Bald Ibis, hunted essentially to extinction by the 17th century, was revived by breeding and rewilding efforts over the last two decades. But the birds—known for their distinc.....»»
US water reservoirs are shrinking and becoming less reliable, new study finds
Major water reservoirs across the continental United States are experiencing longer, more severe, and more variable periods of low storage than several decades ago, a new study reports. The problems are most severe in the western and central United S.....»»
Study tracks decades of extreme heat, cold in Upper Midwest
Researchers analyzed meteorological data from nine Upper Midwest states from 1979–2021, tracking trends in extreme heat and cold over every 4-kilometer square of that territory. They found striking regional differences in the extremes. Many parts o.....»»
Twisted molecular wires exhibit high single-molecule conductance
From the high-voltage wires that carry electricity over long distances, to the tungsten filaments in our incandescent lights, we may have become accustomed to thinking that electrical conductors are always made of metal. But for decades, scientists h.....»»
Research shows reducing future global flooding hinges on cutting greenhouse gas emissions
Pioneering research forecasts that worldwide flooding is likely to be significantly worse in future decades if countries fail to meet official pledges to cut carbon emissions......»»
Cleanup hopes for neighbors of Mexico"s "toilet bowl" wastewater dam
On the banks of a wastewater dam in central Mexico, under a dense cloud of mosquitoes, Yury Uribe is finally seeing hope after spending decades in "environmental hell.".....»»
Advanced materials could provide more durable metals for fusion power reactors
For many decades, nuclear fusion power has been viewed as the ultimate energy source. A fusion power plant could generate carbon-free energy at a scale needed to address climate change. And it could be fueled by deuterium recovered from an essentiall.....»»
Microsoft cracks down on Windows 11 upgrade requirements
The latest Insider Build of Windows 11 has patched the "/product server" workaround that let old CPU users easily bypass the system requirements check......»»
Steam has one big problem with its smallest games

Geophysicists find link between seismic waves called PKP precursors and strange anomalies in Earth"s mantle
For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth's lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds......»»

Why do plants wiggle? New study provides answers
In a new study, physicists from the United States and Israel may have gotten to the bottom of a quirky behavior of growing plants—and a mystery that intrigued Charles Darwin himself during the later decades of his life......»»
New analysis of Webb data measures universe expansion rate, finds there may not be a "Hubble tension"
We know many things about our universe, but astronomers are still debating exactly how fast it is expanding. In fact, over the past two decades, two major ways to measure this number—known as the "Hubble constant" —have come up with different ans.....»»
