In 2020 and 2021, California experienced fire activity unlike anything recorded in the modern record. When the smoke cleared, the amount of burned forest totaled ten times more than the annual average going back to the late 1800s. We know that wildlife in western forests evolved with changing habitat and disturbances like wildfire. Each species responds differently, some benefiting from openings, others losing critical habitat. What we don't know is... Read more ›

The burden of heat-related mortality during the summer of 2022 in Europe may have exceeded 70,000 deaths according to a new study. The authors of the study revised upwards initial estimates of the mortality associated with record temperatures in 2022 on the European continent. Read more ›

When bacteria build communities, they cooperate and share nutrients across generations. Researchers have been able to demonstrate this for the first time using a newly developed method. This innovative technique enables the tracking of gene expression during the development of bacterial communities over space and time. Read more ›

Contrary to the commonly-held view, the brain does not have the ability to rewire itself to compensate for the loss of sight, an amputation or stroke, for example, say scientists. The researchers argue that the notion that the brain, in response to injury or deficit, can reorganize itself and repurpose particular regions for new functions, is fundamentally flawed -- despite being commonly cited in scientific textbooks. Instead, they argue that... Read more ›

LUCA, the 'last universal common ancestor' of all living organisms, lived 4.32 to at most 4.52 billion years ago. What LUCA looked like is unknown, but it must have been a cell with among others ribosomal proteins and an ATP synthase. Read more ›

 The research makes it clear that ensuring the sustained well-being of our planet requires a more serious commitment toward new carbon dioxide removal technologies, and a faster scale-up of their production. Read more ›

Despite public perception, the Antarctic ozone hole has been remarkably massive and long-lived over the past four years; researchers believe chlorofluorocarbons (CFCs) aren't the only things to blame. Read more ›

Scientists have discovered that bacteria can create something like memories about when to form strategies that can cause dangerous infections in people, such as resistance to antibiotics and bacterial swarms when millions of bacteria come together on a single surface. The discovery -- which has potential applications for preventing and combatting bacterial infections and addressing antibiotic-resistant bacteria -- relates to a common chemical element bacterial cells can use to form...

If you look at massive galaxies teeming with stars, you might be forgiven in thinking they are star factories, churning out brilliant balls of gas. But actually, less evolved dwarf galaxies have bigger regions of star factories, with higher rates of star formation. Now, University of Michigan researchers have discovered the reason underlying this: These galaxies enjoy a 10-million-year delay in blowing out the gas cluttering up their environments. Star-forming... Read more ›

Using 700 years' worth of wave data from more than a billion waves, scientists have used artificial intelligence to find a formula for how to predict the occurrence of these maritime monsters. Long considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs. Read more ›

Using the James Webb Space Telescope, CECILIA Survey receives first data from galaxies forming two-to-three billion years after the Big Bang. By examining light from these 33 galaxies, researchers discovered their elemental composition and temperature. The ultra-deep spectrum revealed eight distinct elements: Hydrogen, helium, nitrogen, oxygen, silicon, sulfur, argon and nickel. The teenage galaxies also were extremely hot, reaching temperatures higher than 13,350 degrees Celsius.

Gamma-ray flares from blazars can be accompanied by high-energy neutrino emission. To better understand this phenomenon, an international research team has statistically analyzed 145 bright blazars. They constructed weekly binned light curves and utilized a Bayesian algorithm, finding that their sample was dominated by blazars with low flare duty cycles and energy fractions. The study suggests that high-energy neutrinos of blazars might be produced mainly during the flare phase. Read more ›

Feeding dogs raw (uncooked) meat increases their risk of excreting E. coli that cannot be killed by a widely used antibiotic -- ciprofloxacin -- researchers have found from a study of 600 healthy pet dogs. Read more ›

Worldwide, coastal river deltas are home to more than half a billion people, supporting fisheries, agriculture, cities, and fertile ecosystems. In a unique study covering 49 deltas globally, researchers have identified the most critical risks to deltas in the future. The research shows that deltas face multiple risks, and that population growth and poor environmental governance might pose bigger threats than climate change to the sustainability of Asian and African...
