These “Living Rocks” Are Living It Up

You might think you’re looking at a bunch of mossy rocks, but you’re actually gazing at some of the world’s oldest living creatures—and they’re doing great.
Communities of microbes gobble up dissolved minerals in water and turn them into these solid, rock-like structures called microbialites. Researchers have found fossilized microbialites that are around 3.7 to 3.5 billion years old, which might represent the oldest organisms found on Earth.
Around a billion years after that, microbialites may have transformed our planet forever—researchers think tha

Air pollution isn't just bad for human health; it also poses an existential threat to certain fly species.
New research from the Max Planck Institute for Chemical Ecology found that elevated ozone levels inhibit mating among flies.
Ozone in the stratosphere helps protect the Earth from dangerous UV radiation. But down here, the gas is a threat to our health, food supply, and biodiversity. The latter is apparent in this recent study, which found that ozone exposure significantly degrades fly pheromones.
When this happens, male and female flies have a hard time recognizing each other, renderi

Bitcoin’s three-year rally may be over, with signs pointing to the leading cryptocurrency entering a prolonged bear market.
That’s according to blockchain data firm CryptoQuant, whose researchers said in a Friday report that investors should be prepared for the end of Bitcoin’s four-year cycle.
Buyer exhaustion means the biggest digital coin could still drop as low as $56,000, the report noted. But it reassured investors that such a move was unlikely — if Bitcoin does drop that low, it would be the sharpest drawdown in a bear market on record.
“Bitcoin demand growth has decisively slowed, s

There are plenty of annual recap lists circulating around this time of year, but few of them involve the amount of work put in by California’s Monterey Bay Aquarium Research Institute (MBARI). Over the past year, researchers guided remotely operated vehicles more than 3,000 feet down to survey the vast biodiversity within some of the oceans’ deepest and darkest regions. The data and footage collected during these trips will help experts fill in the gaps towards understanding the planet’s hardest-to-reach ecosystems.
To celebrate the past 12 months of discoveries, MBARI released a video highli

You may have seen headlines or social media posts talking about a weakening of Earth’s magnetic field, specifically over the South Atlantic.
It sounds dramatic, and a little scary. Is Earth losing its protective shield? Are we in danger? What exactly does this mean for people on the ground?
To get the facts straight, we spoke with Manoj Nair, a senior research scientist at CIRES at the University of Colorado and an affiliate at NOAA, who studies Earth’s magnetic field for a living.
His takeaway is reassuring: this is fascinating science and important for satellites, but not something the av

Standard Chartered has significantly tempered its bullish price projections for Bitcoin over the next five years.
“I still see Bitcoin continuing to print fresh all-time highs going forward, but I think the pace will be slower than previously expected,” Standard Chartered Global Head of Digital ***** ets Research Geoffrey Kendrick said in an email last week.
Kendrick said in a Dec. 9 note that Standard Chartered was forced to reassess its price targets amid Bitcoin’s recent price action. The

Every animal with a brain needs sleep — and even a few without a brain do, too. Humans sleep, birds sleep, whales sleep and even jellyfish sleep.
Sleep is universal “even though it’s actually very risky,” said Paul-Antoine Libourel, a researcher at the Neuroscience Research Center of Lyon in France.
When animals nod off, they're most vulnerable to sneaky predators. But despite the risks, the need for sleep is so strong that no creature can skip it altogether, even when it's highly inconvenient.
Animals that navigate extreme conditions and environments have evolved to sleep in extreme ways —

Mohit Verma's laboratory at Purdue University has developed a faster and more affordable paper-based biosensor for identifying genetically modified corn and soybeans, providing farmers with more accessible molecular diagnostic tools.
This new GM crop biosensor, which has a patent pending, uses a method called loop-mediated isothermal amplification (LAMP) to achieve more cost-effective and efficient testing than more expensive tools already on the market, according to a Purdue report shared by Phys.org.
The research team used their previous work in rapidly detecting highly pathogenic avian in

Numerous stories have been written about the growing swarm of Starlink satellites in low earth orbit (LEO) over the past few years, as astronomers grow increasingly worried about the crafts’ impact on their observation equipment. Launched by Elon Musk’s ******* eX, each satellite has the potential to disrupt astronomy through both radio emissions and light pollution — and as the number of satellites grows, so too does the amount of interference.
Now, a new study by researchers at NASA is warning that obstructions caused by ******* eX and other private satellite companies are becoming so sever

A group of researchers say it's time for academia to get serious about studying UFOs.
The movement, championed by the Society for UAP Studies, is wrapping up an international conference aimed at establishing a new discipline dedicated to studying unidentified anomalous phenomena (or UAPs, the more formal term for UFOs).
Michael Cifone, the society's co-founder and president, said he's interested in what he calls "the empirical weird."
His catch-all phrase encompasses things that blur the lines between the real and the possible, phenomena that defy easy explanation: the spiritual, the parano

Maggots may be the key to more accurately determining when people died, according to Florida researchers, pointing to the genetic makeup of larvae.
The findings build on previous methods that investigators have used to determine when people died. Currently, investigators rely on the outer appearance of maggots and the presence of eggs on decomposing bodies to estimate people's death dates.
However, researchers at Miami’s Florida International University (FIU) have found that by observing maggots’ genes and metabolic changes, investigators can better estimate when people died.

NASA warns satellite boom could ruin 96% of telescope images

A new NASA-led study shows that the increasing number of satellites in low-Earth orbit could ruin up to 96% of images from some orbiting telescopes and **** e observatories.
“The urgency starts in the moment we’re seeing a very rapid increase in the number of satellite constellations, in particular, not the satellites that have been launched, but in the satellites that are being proposed,” Dr. Alejandro Serrano Borlaff, research scientist at NASA Ames Research Center and co-author of the study, told ABC News. “Before these satell

A prehistoric bird that lived and died 120 million years ago has presented forensic paleontologists with a baffling medical mystery.
Somehow, it managed to die with more than 800 tiny pebbles in its throat – a situation that researchers think almost certainly caused its demise. But why was the sparrow-sized bird swallowing the stones in the first place?
It's a discovery that raises some interesting questions about the diet, behavior, and physiology of prehistoric birds – especially since the mass of stones discovered in the esophagus of the newly discovered Chromeornis funkyi is unlike anyth

Retired astronaut and current Sen. Mark Kelly (D-Ariz.) celebrated NASA’s “pretty exciting” announcement on Thursday after the ****** e agency highlighted how scientists found sugars essential for life on samples of a near-Earth asteroid.
While the discovery of the sugars glucose and ribose — which NASA’s OSIRIS-REx ****** ecraft gathered from the asteroid Bennu — did not indicate “evidence of life,” the findings show that “building blocks of biological molecules were widespread throughout the solar system,” according to NASA.

Artificial intelligence companies are quickly expanding without the protections experts say are needed.
According to NBC News, the Winter 2025 AI Safety Index reviewed eight companies across 35 indicators and found that these companies are rolling out increasingly powerful systems while leaving gaps in oversight.
The index evaluated areas such as risk-assessment procedures, information sharing processes, governance structures, and safety-research support and documented inconsistent or absent protocols and protections across the industry. The organizations scoring lowest are racing to match o

Concerns around quantum computing have resurfaced, with some ****** ysts warning it could pose a serious threat to Bitcoin’s future.
While K33 Research believes these fears are overblown, the long-term Bitcoin price prediction could shift dramatically if this view proves wrong.
According to Vetle Lunde, Head of Research at K33, roughly 6.8 million BTC may be at risk if quantum machines advance far enough to break current encryption standards.
However, Lunde emphasized that “the timeline for such breakthroughs remains uncertain, and exchanges are unlikely to allow compromised coins to circul

A new study is flipping the script on how we think about renewable energy, and it is revealing a surprising flaw in the way a major industry is funded.
UK researchers Colm O'Shea, Piers Horne, and Mark Maslin found that wind power has delivered more than $132.4 billion in total savings for consumers since 2010. Besides the work wind power has done to clean up the UK's electricity grid, this is also a major win for families and the economy.
Plus, it is a reminder that clean energy is more than just an environmental upgrade.
From 2010 to 2023, wind generation cut costs by $195.2 billion, incl

The Bennu asteroid, a ******* e rock not too far from Earth that is rich in carbon, continues to be a trove of information for scientists keen to learn about how life may have begun in our solar system.
More than two years ago, a robotic ******* ecraft dropped off a delivery of rocky samples from the surface of Bennu. The material has been a gift to the world's researchers, who soon found signs that asteroids that collided with Earth billions of years ago may have given rise to life on Earth.
In the latest discoveries, multiple teams of researchers have found a bevy of interesting characteri

Initial jobless claims dropped to 191,000—far below the 219,000 forecast—marking the lowest level since 2022, according to Kathy Jones, Chief Fixed Income Strategist at Schwab Center for Financial Research. Jones cautioned: "Good news, but the data can be a bit volatile around the holidays."
The unexpectedly strong labor market print comes just one day after December Fed rate cut odds surged to 88.8% following flat import price data, with the robust claims figure now raising questions about whether the Fed needs to ease as aggressively as markets anticipate.

Instead of stopping to smell the flowers, scientists suggest stopping to smell your farts.
While the thought may be enough to make your stomach turn, scientists at Johns Hopkins Medicine say the gas behind the foul, rotten-egg-smelling stench, known as hydrogen sulfide, can help protect aging brain cells from Alzheimer’s disease.
While the smelly gas is highly toxic in large quantities, smaller doses may provide some serious health benefits, Johns Hopkins researchers noted in a study published in an issue of the Proceedings of the National Academies of Science.

Lasers are everywhere. Whether for barcode scanners, hair removal treatments or fiber-optic internet connections, these beams of light power our everyday lives. Their history dates back to Einstein’s theories in the 1910s and experiments funded by the U.S. government in the 1950s. It took decades for lasers to go from theory to research prototypes to ubiquitous technology.
Many discoveries follow a similar path, including right here in Tennessee.

Africa’s forests have turned from a carbon sink into a carbon source, according to research that underscores the need for urgent action to save the world’s great natural climate stabilizers.
The alarming shift, which has happened since 2010, means all of the planet’s three main rainforest regions — the South American Amazon, Southeast Asia, and Africa — have gone from being allies in the fight against climate breakdown to being part of the problem.
Human activity is the primary cause of the problem. Farmers are clearing more land for food production. Infrastructure projects and mining are ex

Scientists Find Popular Diabetes Drug Impacts the Brain in Surprising Study

With buzzy medications like Ozempic and Mounjaro making headlines for blood sugar management, it’s easy to forget that some medications have been helping patients with type 2 diabetes for decades. Metformin is a popular one. But while this medication has been around for more than 60 years, scientists are uncovering what it does to the brain.
New research published in the journal Science Advances identifies a brain pathway that metformin seems to work through (along with the impact it has on other areas of the body)

Ubiquitous industrial chemicals and pesticides have a "toxic effect" on germs that play a key role in maintaining human health and could be a threat to male reproductive health, according to two teams of scientists.
"Many chemicals designed to act only on one type of target, say insects or fungi, also affect gut bacteria," says the University of Cambridge’s Indra Roux, whose team’s probe of more than 1,000 potential contaminants found 168 that are likely a danger to the human microbiome.
"Most of these chemicals had not been previously reported to have antibacterial properties," the research
