Phys.org / Why sugar breakdown matters beyond energy—new insights into how it makes cells move
It has long been known that our bodies derive energy from sugar. Researchers at RPTU University Kaiserslautern-Landau have now discovered that sugar breakdown produces an intermediate product that is also crucial for the ...
Phys.org / Milk-derived nanoparticles may enable physicians to target aggressive bile duct cancer
Mayo Clinic researchers have developed a promising new way to deliver treatment directly to cholangiocarcinoma tumors, a rare and aggressive bile duct cancer with limited treatment options, using milk-derived nanoparticles ...
Phys.org / Q&A: Reevaluating reaction rates to better understand the stars
Thermonuclear reaction rates power the models that explain how stars live, explode and create the elements. A new study co-authored by NC State faculty member Richard Longland provides a comprehensive, statistically grounded ...
Phys.org / Could reduced air pollution from climate mitigation boost crop yields and lower hunger risk?
An international research team used multiple global agroeconomic models and found that climate mitigation consistent with the 1.5 °C target could raise global hunger risk in 2050 by 17% (56 million people) compared with ...
Phys.org / Coastal ocean chemistry now substantially shaped by humans
A global analysis of more than 2,300 seawater samples from more than 20 field studies around the globe indicates that human-made chemicals make up a significant portion of organic matter in coastal oceans. The international ...
Phys.org / High-resolution electron microscopy sheds light on the cellular responses to stress
An international team led by researchers from the University Medical Center Göttingen (UMG), Germany, has used advanced electron microscopy technologies to capture key cellular mechanisms of stress resistance with near-atomic ...
Phys.org / Climate action could prevent over 13 million premature deaths, but equity choices matter for global health
A new study published in The Lancet Global Health reveals a previously underappreciated tension at the heart of international climate negotiations: policies designed to protect developing countries from bearing an unfair ...
Phys.org / Microbes in Antarctica survive the freezing and dark winter by living on air
Winter in Antarctica is long and dark. Temperatures remain well below freezing. In many places, the sun sets in April and does not rise above the horizon again until August. Without sunlight, photosynthetic life such as plants, ...
Phys.org / Whale song remix: Study shows that humpbacks shift pitch when a neighbor joins in
A humpback whale alters the pitch of its song when joined by a neighboring singer, a finding that opens a new chapter in the ongoing effort to understand whale song, some of the most structurally and acoustically complex ...
Phys.org / Sugar-processing enzyme has a hidden second job—controlling when cells divide
A metabolic enzyme studied for over seven decades has a hidden second function—it can unwind RNA and promote cell cycle progression, an additional function beyond its role in energy production, according to a new study ...
Phys.org / Computational model predicts telomere length from routine biopsy slide images
A new computational tool infers changes occurring at the ends of the chromosomes housing our DNA. It does so by detecting structural alterations in cells and tissues captured in images taken of routine medical biopsies, according ...
Phys.org / Building a reference manual for how cells connect with each other
Every multicellular organism, from tiny worms to humans, elephants, and whales, needs a way for their cells to connect with each other to form tissues, organs, and organize their overall body plan. Cells have a variety of ...
