Climate change could heat the Earth right into a new ice age

POPULAR MECHANICS - Like all of us, the Earth goes through phases. Over the course of its existence, the planet’s climactic processes have relied on certain mechanisms to regulate its temperature—mechanisms that can have profound impacts on the surface of the planet and, in turn, the life that inhabits that surface. During the Jurassic period...

Scientists think a crumbling supercontinent may have kickstarted life on Earth

POPULAR MECHANICS - For the past three decades, scientists have been bad-mouthing a sizable chunk of Earth’s history (roughly 1.8 billion years ago to 800 million years ago) by giving it nicknames like the “Barren Billion,” the “Boring Billion,” or the Earth’s “Middle Ages.” At first glance, the monikers may be warranted—compared to more dynamic...

Dehydration makes elite mice exercise more, not less. What this means for humans

STUDY FINDS - Common sense tells us that when the body is dehydrated, physical performance declines. Athletes and coaches have long known that even modest fluid loss can hurt endurance and speed. However, research focusing on laboratory mice has uncovered a puzzling exception. The fittest animals actually ran more, not less, when deprived of water...

California’s drying Salton Sea harms the lungs of people living nearby, say researchers

THE GUARDIAN - Chemical-laden dust from southern California’s drying Salton Sea is probably harming the lungs of people around the shrinking body of water, and the effects are especially pronounced in children, new peer-reviewed research from the University of California, Irvine, shows. A separate peer-reviewed study from the University of California, Riverside, also found the...

FROnt Surface Type Irradiator, or FROSTI, will allow future detectors to run at higher laser powers, reducing noise and expanding capabilities

PHYSICS WORLD - Future versions of the Laser Interferometer Gravitational Wave Observatory (LIGO) will be able to run at much higher laser powers thanks to a sophisticated new system that compensates for temperature changes in optical components. Known as FROSTI (for FROnt Surface Type Irradiator) and developed by physicists at the University of California Riverside...

The lung microbiome is also beneficial to our health — and harmful dust can alter it

DISCOVER MAGAZINE - When it comes to the microbiome, researchers have extensive knowledge of the microbial community living in our guts. The lungs, however, are a different story. While it may sound odd, microbes do live in our lungs, and breathing in certain substances, like certain dust, can cause harm to the lung microbiome. A...

Arctic Ocean methane 'switch' that helped drive rapid global warming discovered

LIVE SCIENCE - The Arctic Ocean was once an important source of greenhouse gases to the atmosphere — and it could become one again, researchers warn. Methane (CH4) is second only to carbon dioxide (CO2) in trapping heat in Earth's atmosphere. Since 2020, human-driven greenhouse gas emissions have increased atmospheric methane by about 10 parts...

Earth may have glowed purple 2.4 billion years ago, says NASA-backed study

DAILY GALAXY - Earth’s familiar green landscape might not have always been so. According to new scientific research published in the journal International Journal of Astrobiology, our planet may have once shimmered in shades of purple, driven by a completely different form of life than we know today. This striking idea doesn’t just reshape our...

Hidden, supercharged 'thermostat' may cause Earth to overcorrect for climate change

LIVE SCIENCE - Earth may respond to the huge quantities of carbon dioxide (CO2) that humans are pumping into the atmosphere by "overcorrecting" the imbalance, which could result in the next ice age arriving on time instead of being delayed by tens of thousands of years, as had previously been predicted. This is due to...

Geothermal gets a head of steam

POLITICO - BLOWING STEAM: Will California remain king of U.S. geothermal energy production? Or will other states snatch the crown? That was the decision before Gov. Gavin Newsom, according to the geothermal industry and its allies, as he weighed signing their two top-priority bills of this session. Newsom signed one and vetoed the other on...

Leeches may be 200 million years older than we thought—and haven’t always sucked blood

SMITHSONIAN MAGAZINE - The biological history of leeches is difficult to study: Their tissue decomposes almost immediately, and their boneless bodies rarely fossilize. But a geological formation in Wisconsin preserved a leech fossil for 437 million years, a new study finds. It’s the first-ever discovery of its kind—and an analysis of the preserved leech suggests...

Leeches weren’t always bloodsucking fiends like today. They used to swallow their prey whole

ZME SCIENCE - Leeches are some of the most hated creatures in the world, even though most people rarely (if ever) see one. We even use the word as an insult. A leech is a parasite, someone who lives only to suck the blood from others. But leeches deserve more respect. A newly described fossil...

Carbon cycle ‘flaw’ can overshoot, plunging Earth into potential Ice Age: Study

INTERESTING ENGINEERING - A new study has provided fresh insights into how Earth recycles its carbon. Rock weathering acts as the slow, reliable mechanism that stabilizes Earth’s climate. The easy explanation is that rain, rocks, and carbon burial keep the climate in check, but new research shows this account may be incomplete. The University of...

Leeches didn't always suck blood — ancient fossils reveal they swallowed prey whole

DISCOVER MAGAZINE - It’s the beginning of the spooky season, which means ghouls, ghosts, and bloodsuckers abound. One of the most famous bloodsuckers in nature is, of course, the leech. These parasites feed on blood and have been used throughout history to treat a whole host of medical problems in humans. Now, for the first...

This leech had an appetite for something other than blood

THE NEW YORK TIMES - If you look around Waukesha County in Wisconsin today, it can be difficult to imagine a tropical coastline teeming with trilobites, the oldest known scorpions and jawless vertebrates. But 437 million years ago, during the Silurian period, these creatures lived and died there, some getting washed into a salty cove...

How global warming today could trigger a future ice age

EARTH.COM - Earth has never stood still when it comes to climate. For billions of years, our planet has cycled between heat and cold, shaping the environment where life evolved. But new research from UC Riverside (UCR) reveals that the story of Earth’s carbon balance is more complicated than once believed. The findings suggest that...

Laser wavefront-correcting device gives LIGO 10x boost to spot distant gravitational waves

INTERESTING ENGINEERING - Gravitational waves, tiny ripples in spacetime caused by cosmic collisions like merging black holes, are almost impossibly faint. Detecting them requires LIGO (Laser Interferometer Gravitational-Wave Observatory), one of the most sensitive instruments ever built. However, there’s a catch. To see farther and catch weaker signals, LIGO needs more powerful lasers, but stronger...

How Earth’s ‘thermostat’ can malfunction, flipping global warming into ice-age level cooling

STUDYFINDS - New modeling shows that global warming events can, under certain conditions, trigger long-term cooling strong enough to resemble ice age conditions, according to researchers at the University of California, Riverside. When the planet experiences large-scale carbon emissions and warming, natural cooling processes can sometimes overshoot and send global temperatures plummeting far below their...

Exoplanet discoveries pass the 6,000 mark, shedding light on how our solar system compares with the rest of the universe

SMITHSONIAN MAGAZINE - Just decades after the first exoplanets were identified, our database of the distant worlds—monitored by the NASA Exoplanet Science Institute—has breached a new threshold. Now, astronomers have officially identified more than 6,000 planets outside our solar system. “This milestone represents decades of cosmic exploration driven by NASA space telescopes—exploration that has completely...

NASA’s extrasolar planet tally officially hits the 6,000 mark

FORBES - NASA reports that its official tally of extrasolar planets has hit the 6,000 mark. This thirty-year milestone has been in the works since two little known Swiss astronomers, Michel Mayor and Didiez Queloz, first detected 51 Pegasi b. The first of the so-called “hot Jupiters” to be detected, “51 Peg” is a gas...
