Snowball Earth was not completely frozen, new study reveals

Researchers at the University of Southampton have found new evidence that Earth’s climate did not completely grind to a halt during its most extreme ice age, a time often called Snowball Earth. This dramatic chapter unfolded during the Cryogenian Period, between 720 and 635 million years ago. Scientists have long…

One simple daily change that could slash depression risk

Spending less time in front of the television and more time on other activities could help prevent major depressive disorder, especially during middle age. That is the conclusion of a new study published in European Psychiatry on behalf of the European Psychiatric Association by Cambridge University Press. Researchers found that…

This kefir and fiber combo beat omega-3 in slashing inflammation

Researchers at the University of Nottingham report that combining specific dietary supplements may provide stronger immune and metabolic support than taking prebiotics or omega 3 alone. Their findings suggest this paired approach could help lower the risk of diseases associated with long term inflammation. The study, published in the Journal…

Just 5 weeks of brain training may protect against dementia for 20 years

Older adults who took part in a short program designed to sharpen how quickly they process visual information were less likely to develop dementia years later. The training, known as speed of processing training, teaches people to rapidly spot visual details on a computer screen and manage increasingly complex tasks…

Changing when you eat dramatically reduced Crohn’s disease symptoms

A randomized controlled trial funded by the Crohn’s & Colitis Foundation found that time-restricted feeding, a type of intermittent fasting, significantly lowered disease activity and systemic inflammation in adults with Crohn’s disease who also had overweight or obesity. Led by researchers at the University of Calgary, the study is the…

Blockbuster weight loss drugs like Ozempic deliver big results but face big questions

Three recently released Cochrane reviews conclude that GLP-1 medications, such as Ozempic, can lead to meaningful weight loss. However, the findings also highlight concerns about the heavy involvement of drug manufacturers in many of the studies. The World Health Organization (WHO) commissioned the reviews to help shape upcoming global guidelines…

Life may have started as sticky goo clinging to rocks

How did life begin? A team of scientists from Japan, Malaysia, the United Kingdom, and Germany believes the answer may involve sticky gels that coated surfaces on early Earth long before the first true cells appeared. Their work, published in ChemSystemsChem, offers a fresh way to think about the origin…

Interstellar comet 3I/ATLAS is spraying water across the solar system

For countless ages, a small chunk of ice and dust traveled alone through interstellar space, like a sealed bottle drifting across a vast cosmic sea. This summer, that traveler entered our solar system and received the name 3I/ATLAS, becoming only the third confirmed interstellar comet ever observed. When researchers at…

Almost every forest bird in Hawaiʻi is spreading avian malaria

A sweeping new study led by a researcher at the University of Hawaiʻi at Mānoa reveals that almost every forest bird species in Hawaiʻi can transmit avian malaria. That widespread ability to spread infection helps explain why the disease shows up nearly everywhere mosquitoes live across the islands. The findings,…

Astronomers shocked by how these giant exoplanets formed

Gas giants are enormous planets made primarily of hydrogen and helium. They may contain dense central cores, but unlike Earth, they do not have solid surfaces you could stand on. In our solar system, Jupiter and Saturn are classic examples. Beyond our neighborhood, astronomers have identified many gas giant exoplanets,…

Depression may be the brain’s early warning sign of Parkinson’s or dementia

While there is currently no cure for Parkinson’s disease or Lewy body dementia, addressing depression early could improve quality of life and overall care for patients as these diseases develop. study published in General Psychiatry provides the most detailed longitudinal evidence to date, demonstrating that depression frequently precedes the diagnosis of…

This ancient animal was one of the first to eat plants on land

Life began in the sea. Around 475 million years ago, plants started spreading from water onto dry ground. Roughly 100 million years later, vertebrate animals followed. Yet even after animals established themselves on land, they remained meat eaters for tens of millions of years, feeding on other animals rather than…

Scientists just made living blood vessels on a chip that act like real ones

Human blood vessels are anything but simple. They bend, branch, narrow, and widen, creating complex pathways that affect how blood moves through the body. For a long time, however, laboratory models treated blood vessels as straight, uniform tubes. While useful, those simplified designs failed to reflect the conditions where many…

Scientists discover how life experiences rewrite the immune system

The COVID-19 pandemic made one thing unmistakably clear: people can experience the same infection in dramatically different ways. Some develop mild symptoms, while others face severe illness. This wide range of outcomes raises a fundamental question. Why do two people exposed to the same pathogen respond so differently? A major…
