In his theoretical model published in 2011, Canadian Allan MacDonald predicted that by twisting two graphene layers at a given angle, in the region of one degree, the interaction of electrons would produce new emerging properties. Seven years later, Spaniard Jarillo-Herrero and his team provided the experimental confirmation, fabricating bilayers of graphene rotated at this “magic angle” that transformed the material’s behavior, giving rise to new properties like superconductivity. “Their work has opened up new frontiers in physics by demonstrating that rotating matter to a given angle allows us to control its behavior, obtaining ...

University of Virginia School of Medicine researchers have revealed how the popular, low-carb ketogenic diet protects against epilepsy seizures and possibly neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Keto, as the diet is commonly known, has been used to reduce seizures in patients with medication-resistant epilepsy since the 1920s. Doctors, however, have been uncertain exactly how the diet does this, even as they identified potential benefits for other brain disorders. A team led by UVA’s Jaideep Kapur, MBBS, PhD, co-director of UVA’s Brain Institute, has found answers. This discovery could ...

Of all the types of breast cancer, triple negative breast cancer (TNBC) is the most aggressive and lacks specific therapies. TNBC also is more likely to metastasize, or travel through the blood stream to spread to other organs, which causes most of breast cancer-related deaths each year. Until now, tracking circulating tumor cells (CTC), a powerful indicator of cancer metastasis, has been challenging because there are very few markers that specifically identify these cells. Looking to find a better way to follow metastasis progression, researchers at Baylor College of Medicine developed a procedure to enhance the ...

The last time you scrubbed a streaky window or polished a porcelain appliance, you probably used a chemical called ammonia.  Also known as ammonium hydroxide when mixed with water, ammonia is more than a common household cleaner. More than 170 million metric tons of it are produced globally every year, with most of it ending up as fertilizer for corn, cotton and soybeans.  UIC researchers are scaling up a system for farmers to produce ammonia in their own backyards. The method, which uses renewable electricity and Earth’s natural resources, appears in the journal PNAS.  “So many people around the world need food. ...

The Korea Research Institute of Standards and Science (KRISS, President Lee Ho Seong) has developed a key materials technology that accelerates the commercialization of all-solid-state batteries (ASSBs)—next-generation batteries designed to intrinsically eliminate the risks of fire and explosion. The Emerging Material Metrology Group at KRISS demonstrated ultra-dense, large-area solid electrolyte membranes by applying a method that coats solid electrolyte powders with multifunctional compounds, reducing production costs to one-tenth of conventional levels. Lithium-ion secondary batteries, which are widely used in electric vehicles ...

Hoboken, NJ., January 12, 2026 — Disinfecting drinking water prevents the spread of deadly waterborne diseases by killing infectious agents such as bacteria, viruses and parasites. Without disinfection, even clear-looking water can carry pathogens that can cause severe and even life-threatening illness, especially in children, older adults, and people with weakened immune systems. Before water disinfection processes were put in place, outbreaks of waterborne diseases such as cholera, typhoid, and dysentery routinely claimed lives, decimating cities and even countries. Disinfecting drinking water is ...

A new study from researchers at Mass General Brigham finds that patients who undergo unscheduled or unplanned cesarean deliveries are at substantially increased risk for experiencing acute psychological stress during childbirth, with effects that can persist for months and impact maternal mental health and early bonding with infants. Results are published in Pregnancy. The study, which followed more than 1,100 women who gave birth at Massachusetts General Hospital, a founding member of the Mass General Brigham healthcare system, found that over 1 in 4 patients who had an unscheduled cesarean delivery experienced clinically significant acute stress shortly after birth, compared with about ...

For the first time, a study from researchers at Scripps Institution of Oceanography at the University of California San Diego integrates climate-related damages to the ocean into the social cost of carbon— a measure of economic harm caused by greenhouse gas emissions.  When ocean damage from climate change, dubbed the “blue” social cost of carbon, is calculated, the study finds that the global cost of carbon dioxide emissions to society nearly doubles. Until now, the ocean was largely overlooked in the standard accounting of the social cost ...

As climate change drives more frequent and severe wildfires across boreal forests in Alaska and northwestern Canada, scientists are asking a critical question: Will these ecosystems continue to store carbon or become a growing source of carbon emissions? New research published this week shows that when forests shift from coniferous—consisting mostly of pines, spruces and larches—to deciduous—consisting mostly of birches and aspens—they could release substantially less carbon when they burn. The National Science Foundation-funded study, led by researchers from the Center for Ecosystem Science and Society (ECOSS) at Northern Arizona University and published in ...

Barcelona, January 15, 2026.
