Researchers at EPFL have developed a chip-scale ultrafast laser that performs on par with traditional tabletop femtosecond lasers. The innovation could make advanced laser technologies far smaller, cheaper, and more accessible for applications ranging from medical diagnostics to atomic clocks.
Scientists examining amber from Goethe’s personal collection discovered three hidden fossil insects, including an extinct ant preserved in extraordinary detail. Advanced 3D imaging allowed researchers to see not only the ant’s outer features but also structures inside its body. The findings offer new clues about the species’ biology and suggest it likely built large nests in trees.
Two specific weather patterns have been identified as capable of increasing the risk of headaches, thanks to physicians at the University of Cincinnati College of Medicine, along with researchers at the Icahn School of Medicine at Mount Sinai, Errex Inc. and Teva Pharmaceuticals.
Food contaminated with harmful bacteria, viruses, parasites or chemicals kills 1.5 million people worldwide each year, with young children worst hit, the World Health Organization warned on Thursday.
Imagine not having access to affordable, healthy food. For many Americans, it's a reality. A new study by researchers at the American Cancer Society (ACS) shows that between 2003 and 2023, nearly five million people in the United States lived in food deserts, places with no grocery stores. Most of these deserts are in poor and rural areas and in places where people rely on public transit. At the same time, the number of food swamps or areas with mostly restaurants/fast-food locations increased n
Alzheimer's disease and related dementias are expected to more than double by 2060. As June marks Alzheimer's and Brain Awareness Month, three University of Florida researchers are working to improve clinicians' ability to distinguish between these diseases—a critical step toward earlier diagnosis and better outcomes.

A recent University of Mississippi study has identified hundreds of counties in the South where HIV prevention and health care may not be keeping pace with the local needs, leaving communities without resources to address the persistent problem. The research, published in Frontiers in Public Health, offers health care and government leaders a new tool for targeting HIV-related support where the need is highest.
In 2006, Carl Koch sued his employer for damages after burn injuries during a workplace accident that left him with chronic pain. The employer accused him of malingering, so the judge admitted a neuroscientist as an expert witness, who testified that he could see Koch's pain on a brain scan. The case was settled for more than ten times the amount the employer initially offered.
Abdominal pain before an important exam, nausea during intense stress, or sudden intestinal problems following difficult life experiences—many people regard such symptoms as a temporary bodily reaction. However, a growing body of evidence confirms that the relationship between the brain and the gut is far deeper. A publication co-authored by Professor Agata Mulak of Wroclaw Medical University indicates that gastrointestinal health is influenced not only by genes, diet and gut bacteria, but also
People with disabilities continue to face major barriers when seeking oral health care, according to new research that explores the perspectives of patients, caregivers and health care professionals in different countries.
Current estimates of hydrogen's climate impact are now sufficiently robust to inform policy and business decision-making, according to researchers in a new review article on the climate impacts of hydrogen emissions.
The chronic disease schistosomiasis wreaks havoc on more than 220 million people around the world, with the vast majority of cases being in sub-Saharan Africa. Despite decades of mass drug administration campaigns, schistosomiasis remains one of the world's most widespread neglected tropical diseases. Rice farmers and their families are particularly at risk, as the parasitic worms that cause the disease are spread by freshwater snails found in the standing water of rice fields.
The CIC biomaGUNE Center for Cooperative Research in Biomaterials has developed pulmonary surfactant nanoparticles (the blend of lipids and proteins that line the alveoli and enables breathing), which are encapsulated in a drug used to treat pulmonary fibrosis. The researchers show that these nanoparticles are highly capable of remaining trapped in the diseased tissue after being administered via the pulmonary pathway. This allows the doses of antifibrotic medication to be cut, and thus reduces
Research into the academic skills of five-year-old children shows that parents' beliefs and cooperation with their kindergarten are more important than the abundance of parental activities at home in supporting the academic skills of five-year-old children.
There is a well-documented puzzle in social epidemiology: Immigrants have better health than the native-born when they first arrive, but they lose this advantage at older ages. Is acculturation to blame—the process by which immigrants adopt the culture and behavior of their new country?
Researchers at the Terasaki Institute for Biomedical Innovation and the University of Arizona College of Medicine have developed a topical gel formulation with 4-aminopyridine (4-AP), to treat burn wounds, achieving near-complete closure in 21 days. The findings are published in the journal Biomaterials.
The thresholds for kidney function currently used to diagnose chronic kidney disease (CKD) reflect a true increase in the risk of serious illness, according to a study from Karolinska Institutet and Leiden University Medical Center published in JAMA. The researchers also show that risk assessment becomes more accurate when two common blood tests, creatinine and cystatin C, are combined to estimate kidney function.
A Concordia-led research team has developed a planning tool that could help hospitals book their operating rooms more efficiently, shorten wait times and better cope with last‑minute emergencies. The researchers developed their model using artificial intelligence tools to plan which operating rooms to open on each day, when each surgery should start and which cases may need to be delayed, all in a single, integrated framework. Their model uses far fewer variables than a widely used previous appr
How do different cancer subtypes arise? Do they originate from distinct cells, or from a single multipotent cell capable of differentiating into multiple cell types? This question, debated for decades in cancer biology, is now gaining new insight thanks to the work of the Laboratory of Experimental Pathology at the University of Liège, in collaboration with researchers from Université Paris Cité and Sorbonne University. The paper is published in the journal Cell Reports.
Michigan state health officials urged parents in several counties to vaccinate babies against measles ahead of schedule this spring as cases multiplied in the state.
