Researchers have discovered a 380-million-year-old heart – the oldest ever found

Researchers have discovered a 380-million-year-old heart – the oldest ever found – alongside a separate fossilised stomach, intestine and liver in an ancient jawed fish, shedding new light on the evolution of our own bodies. The new research, published today in Science, found that the position of the organs in the body of arthrodires – an […]

Pollution exposure in infancy alters gut microorganisms, may boost disease risk

September 6, 2022 – Exposure to air pollution in the first six months of life impacts a child’s inner world of gut bacteria, or microbiome, in ways that could increase risk of allergies, obesity and diabetes, and even influence brain development, suggests new CU Boulder research. The study, published this month in the journal Gut Microbes, is the […]

WMO predicts first “triple-dip” La Niña of the century

Geneva, 31 August 2022 – It is likely that the protracted La Niña event will last until at least the end of the year, becoming this century’s first “triple-dip“ La Niña, spanning three consecutive northern hemisphere winters (southern hemisphere summers), according to a new update from the World Meteorological Organization. The WMO El Niño/La Niña […]

Hidden Microearthquakes Illuminate Large Earthquake-Hosting Faults in Oklahoma and Kansas

Using machine learning to sift through a decade’s worth of seismic data, researchers have identified hundreds of thousands of microearthquakes along some previously unknown fault structures in Oklahoma and Kansas. The newly identified microearthquakes allowed the seismologists to map and measure earthquake clusters in the region, which has experienced unusual levels of seismicity due to […]

Scientists have calculated what can unbalance El Niño

Physicists and mathematicians of the Ural Federal University (UrFU) have calculated how external factors affect the behavior of El Niño – atmospheric and oceanic processes in the Pacific region. In the mathematical model, they accounted for wind, humidity, temperature, ocean currents, and other parameters that can lead to unpredictable El Niño results. This is a […]

New model developed to predict landslides along wildfire burn scars

A wildfire followed by an intense rainstorm is often a recipe for disaster. Without vegetation to cushion rainfall, water runoff can turn into a fast-moving, highly destructive landslide, called a “debris flow,” which often has the power to wipe out cars, homes and highways — sometimes resulting in casualties. Northwestern University researchers supported by the U.S. National […]

How the Earth is Changing

Climate change is a complicated phenomenon with a variety of both abrupt and gradual effects that scientists are working hard to uncover. Emerging findings on how various ecosystems are responding to a changing climate, stemming from long-term research conducted through the National Science Foundation’s 40-year-old Long-Term Ecological Research (LTER) program, have now been published in […]

Mountain events could improve safety with ultra-high resolution weather models

In late May of 2021, 172 runners set out to tackle a 100-kilometer (62-mile) ultramarathon in northwestern China. By midday, as the runners made their way through a rugged, high-elevation part of the course, temperatures plunged, strong winds whipped around the hillslopes and freezing rain and hail pummeled the runners. By the next day, the […]

Risk of death rises as climate change causes nighttime temperatures to climb

Excessively hot nights caused by climate change are predicted to increase the mortality rate around the world by up to 60% by the end of the century, according to a new international study that features research from the UNC Gillings School of Global Public Health. Ambient heat during the night may interrupt the normal physiology […]

Tonga Eruption Blasted Unprecedented Amount of Water Into Stratosphere

The huge amount of water vapor hurled into the atmosphere, as detected by NASA’s Microwave Limb Sounder, could end up temporarily warming Earth’s surface. When the Hunga Tonga-Hunga Ha’apai volcano erupted on Jan. 15, it sent a tsunami racing around the world and set off a sonic boom that circled the globe twice. The underwater eruption in […]

Considering catastrophe: high-impact, low-probability climate scenarios “dangerously underexplored”

Researchers call for a new “Climate Endgame” agenda and say far too little work has gone into understanding the mechanisms by which rising temperatures might pose a “catastrophic” risk to society and humanity: For instance, if temperature rises are worse than many predict or cause cascades of events we have yet to consider, or indeed […]

Scientists reveal distribution of dark matter around galaxies 12 billion years ago–further back in time than ever before

A collaboration led by scientists at Nagoya University in Japan has investigated the nature of dark matter surrounding galaxies seen as they were 12 billion years ago, billions of years further back in time than ever before. Their findings, published in Physical Review Letters, offer the tantalizing possibility that the fundamental rules of cosmology may differ […]

Bacteria that causes rare disease Melioidosis discovered in U.S. environmental samples

The Centers for Disease Control and Prevention (CDC) has identified for the first time in domestic environmental samples the bacteria that causes a rare and serious disease called melioidosis. The bacteria, Burkholderia pseudomallei or B. pseudomallei, was identified through sampling of soil and water in the Gulf Coast region of Mississippi. It is unclear how […]
