A study that assesses the effects of wildfires over two decades shows that wildfire smoke significantly raises ground-level ozone and contributes to excess deaths from wildfire smoke in the United States each year. The research, led by Minghao Qiu, Ph.D., of Stony Brook
The Department of Defense has released a fresh batch of images and transcripts relating to reports of unidentified anomalous phenomena, formerly known as UFOs, including pictures and descriptions from NASA's Apollo missions to the moon.
In the shadow of the 2008 global financial crisis, trust in the financial system was at a historic low. Banks had failed, markets had collapsed, and confidence in central institutions had been deeply shaken.
When species are subjected to changing environments, they can survive in their current location through genetic adaptation. However, this ability is not unlimited. In a study published in PNAS, biomathematician Jitka Polechová of the University of Vienna shows that, even when
For decades, Antarctica seemed to defy global warming. Since satellites began monitoring the poles in the late 1970s, the seasonal growth and retreat of Antarctic sea ice—frozen seawater that expands around the continent each winter—appeared remarkably resilient. It was often
The Milky Way's galactic bulge, the bulbous region that surrounds the galactic center, contains a dense collection of stars, planets, and other free-floating objects. This region has been studied for decades with numerous ground-based and space-based telescopes, including
When the Atlantic herring colonized the Baltic Sea thousands of years ago, it needed to adapt to the low salinity. Genes with a vital role in the functioning of sperm, eggs and embryos were crucial to this adaptation. A new study by researchers from Uppsala University and other
Artificial intelligence has crossed a threshold in the modern workplace. It is being used for everything from helping employees manage schedules to supporting financial forecasts. A similar shift is now unfolding inside research laboratories.

Aerospace engineers have to consider numerous factors when designing a spacecraft, but one that comes up more and more often is the need to design against micrometeoroids and orbital debris (MMOD). While most designers understand the threat, designing structural solutions
As seismic waves travel through Earth, they gradually lose energy, a process called attenuation. That energy loss doesn't happen uniformly—some features in the crust sap far more energy from seismic waves than others. Researchers can map underground features by watching where
At some 60 billion times the mass of the sun, this dark void could be home to a pair of black holes that are due for a cosmic collision.
Protein language models are artificial intelligence tools which help engineer proteins with useful properties, including completely new structures never seen before in nature.
Recent satellite remote sensing surveys have identified 280 stone structures spread across the Atbai desert in Sudan. Twenty of these structures were previously identified by fieldwork or informal surveys, but were not systematically studied as a regional tradition. Now, new
We are all born completely helpless, with little of the knowledge and skills we will need to survive as adults. Even our ability to communicate is almost entirely learned from our parents or caregivers.
As a child, the mere glimpse of a spider used to send me screaming and running for cover. I was convinced that spiders were my enemies. I thought they were out to get me.
When earthquakes struck Turkey and Syria in February 2023, more than 50,000 people were killed and thousands more were injured.
Accurate experiments on how ocean warming affects marine life are vital to ensure we can best prepare for the future, protect our food sources, and help safeguard ocean ecosystems. But some of these experiments may miss how species actually respond to rising temperatures.
