At a time when more than half the American diet comes from processed, packaged foods, the FDA has new rules aimed at helping people make healthier choices in the grocery store.
Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but a new analysis extends the chart of life to nearly 2 billion years ago. The chart shows the relative ups and downs in species counts, telling scientists about the origin, diversification, and extinction of ancient life. With this new study, the chart of life now includes life forms from the Proterozoic Eon, 2,500 million to 539 million years ago.
A new study about Earth's northernmost seafloor hydrothermal system shows even more variety in vent styles than previously thought. The study has important implications for understanding the origin of these vents and assessing their global-scale impact on the Earth-Ocean system. The study also has implications for understanding and searching for habitable environments, and potentially even life on other ocean worlds in our outer solar system, according to the study's authors.
Started during the pandemic, hundreds of hospitals in 39 states deliver acute inpatient care in people's homes. The popular program had a five-year extension in a stopgap spending agreement that is now in doubt.
Nearly 70 petrochemical companies across the nation, including 30 in Texas, are sending millions of pounds of pollutants into waterways each year due to weak or nonexistent regulations, according to a report published by the watchdog group Environmental Integrity Project. The report analyzed wastewater discharges from petrochemical companies that produce plastics across the U.S., finding that a majority of the facilities had violated Clean Water Act permits and few were punished.
"History" can seem big and imposing. But it's always intensely personal it's all of our individual experiences that add up to historical events.

Researchers developed a laser-based artificial neuron that fully emulates the functions, dynamics and information processing of a biological graded neuron, which could lead to new breakthroughs in advanced computing. With a processing speed a billion times faster than nature, chip-based laser neuron could help advance AI tasks such as pattern recognition and sequence prediction.
Opening new doors for the development of nanotechnologies in medicine and other fields, scientists recreate and compare two natural mechanisms to better program the timescale of molecular communication and functionality.
In the first study of its kind, research led by the Centre for Addiction and Mental Health (CAMH) sheds light on the ethical complexities and systemic barriers facing scientists conducting cannabis research funded by the for-profit cannabis industry.
A brotherly research duo has discovered that when the Large Hadron Collider (LHC) produces top quarks -- the heaviest known fundamental particles -- it regularly creates a property known as magic.
A recently published, comprehensive systematic review and meta-analysis has added to the growing body of evidence showing that beef can be enjoyed in a heart-healthy diet.
Antibodies can improve the rehabilitation of people with acute spinal cord injury. Researchers have investigated this with promising results. For the first time, it was possible to identify patient groups that displayed a clinically relevant treatment effect.
Arizona State University and Banner Alzheimer's Institute researchers, along with their collaborators, have discovered a surprising link between a chronic gut infection caused by a common virus and the development of Alzheimer's disease in a subset of people.
Scientists have unveiled groundbreaking research on the origins of lunar water, offering insights that could reshape our understanding of the Earth-Moon system and the broader solar system. The pioneering study explores the isotopic signatures of lunar water, revealing a mix of indigenous and cometary sources.
The PillBot, resembling an ordinary pill, contains a miniature camera and sensors that allow it to traverse the digestive system, capturing and transmitting images and videos to detect conditions such as ulcers, bleeding, and other abnormalities
A new study finds nearly 50 hidden relatives of Pterodactylus, the first pterosaur. Joined by its newly discovered relatives, Pterodactylus's 'family' now encompasses tiny flaplings, a host of teenagers, some mums and dads and even a few large old seniors. Fluorescing bones stimulated by powerful LED UV torches, revealed invisible details of the head, hands and feet of Pterodactylus.
This editorial reviews the impact of phytochemicals on metabolic diseases, emphasizing their potential in reducing inflammation and improving health outcomes.
Kaempferol's role in Treg development is linked to Aldh1a2 activation in dendritic cells, highlighting its potential in suppressing inflammation and allergies.
Probiotics can reduce antibiotic-associated diarrhea but don't fully restore gut microbiota. Further studies are essential to evaluate their long-term effects.
This study reveals how SARS-CoV-2 infection significantly alters human milk composition, while COVID-19 vaccination causes minimal, transient changes, underscoring the safety of breastfeeding during vaccination.
The holiday season can be a joyous time, but it can also bring about stress and loneliness, impacting both our brain health and overall well-being. Spotting early signs of mental decline in ourselves and our loved ones can be tricky, and understanding how to manage these feelings is important. We had the pleasure of speaking with Dr. Sharon A. Brangman, who brings a wealth of experience as a Trustee of the McKnight Brain Research Foundation.
New findings in mice have uncovered a crucial mechanism linking neuronal activity to mitochondrial function, researchers report, revealing a potential pathway to combat age-related cognitive decline. Mitochondria play a pivotal role in meeting the dynamic energy demands of neuronal activity, producing adenosine triphosphate (ATP) primarily via oxidative phosphorylation (OXPHOS).
AI technology is changing our lives forever. This is one of the reasons that the market for it will be worth $184 billion this year. One of the biggest changes is in the marketing profession. Digital marketers are especially reliant on AI.
