Phys.org / Recovered wild maize gene boosts crop protein without yield loss
Maize (Zea mays L.) plays an important role in global food security. During 9,000 years of maize domestication and breeding, however, protein content was not a major breeding target. Consequently, many beneficial gene variants ...
Medical Xpress / Healthy pancreas shows layered ducts and rare cells tied to aggressive tumors
Scientists at the Free University of Brussels (VUB) have taken a major step forward in pancreatic cancer research. By mapping a healthy pancreas in detail down to the cellular level, they discovered that specific, rare cells ...
Phys.org / Gold nanoparticles unlock vibrant structural colors across the visible spectrum
Colloidal photonic glasses offer an appealing way to produce vivid colors without any chemical dyes—but so far, a stubborn optical effect has long prevented them from generating a true red color. Now, Yuwon Jeon and colleagues ...
Medical Xpress / Defective HIV copies explain most persistent traces in blood following treatment, study finds
Antiretroviral drugs for HIV infection have enabled most people living with the virus to live long and healthy lives. However, a small portion of people experience detectable—and worrisome—traces of the virus that causes ...
Phys.org / Mount Etna eruptions reveal carbon dioxide and water can trigger separate explosive paths
The plumbing systems of volcanoes are vast and complex. But they aren't consistent, even in the same volcano. A Cornell-led collaboration found very different mechanisms behind two historic eruptions of Mount Etna in Italy. ...
Medical Xpress / FDA approves Xocova for COVID-19 postexposure prophylaxis
The U.S. Food and Drug Administration has approved Shionogi's Xocova (ensitrelvir), an oral antiviral, for postexposure prophylaxis (PEP) of COVID‑19 in adults and adolescents aged 12 years and older.
Phys.org / New buried-growth process enables 2D arrays of position- and orientation-controlled diamond qubits
Researchers at Kanazawa University, in collaboration with Diamond and Carbon Applications (Germany), have developed a buried-growth process for nitrogen–vacancy (NV) centers in diamond using microwave plasma chemical vapor ...
Phys.org / Warming unlocks ancient carbon in Tibetan permafrost, triggering climate tipping point
A new study in Nature Communications finds a critical climate tipping point in Tibetan permafrost ecosystems. Warming of 2–4 degrees Celsius triggers a self-reinforcing cycle of carbon release that could significantly accelerate ...
Tech Xplore / A low-tech solution to the 6G problem—metacrystal panels offer cheap way to guide wireless signals around corners
Basements, tunnels, large buildings—a weak Wi-Fi or mobile signal in these hard-to-reach places is frustrating. The usual solution is to add more electronics like routers, repeaters and base stations. Yet, as we move towards ...
Medical Xpress / Extreme heat at the World Cup: Are FIFA's safeguards enough?
On a midsummer day in Miami, temperatures can exceed 32°C (90°F) with high humidity. In a full stadium of 65,000 fans, it can be several degrees hotter, posing a potential health risk to players.
Medical Xpress / Shiga-producing E. coli infections becoming more resistant to antibiotics, study finds
Resistance to antimicrobial agents is rising among human infections with Escherichia coli bacteria that produce the Shiga toxin, according to a study analyzing data from nearly 2,000 infections in the United States between ...
Phys.org / How positive tipping points may be the key to protecting tropical rainforests
The world's tropical rainforests are edging towards collapse. But knowing how to stop deforestation isn't enough to drive action. The challenge is aligning all the pieces of the puzzle to initiate substantial change. Now ...
