Phys.org / Anger, hope and compassion do little to spur more climate donations
Emotional mechanisms are frequently used to inspire good environmental behavior. But how effective are they at inspiring actual sustainable change? Perhaps not as much as previously believed, according to a new study that ...
Phys.org / New analysis reconstructs the dawn of dinosaurs and other reptiles
About 252 million years ago, at the end of the Permian Period, a large proportion of species on Earth rapidly became extinct. After this mass extinction, many groups of organisms began to recover, while reptiles known as ...
Phys.org / Structural study explains how cells stabilize protective membrane pockets
Our cells' membranes have many functions. They not only provide mechanical protection but also precisely control which substances enter or leave cells. If they fail to perform these tasks, disease can result. Their structure ...
Phys.org / Radiation-tolerant rotifers rebuild broken chromosomes over successive generations
DNA repair mechanisms are essential for maintaining the integrity of our genome. When they malfunction, they can cause disease or contribute to the development of cancer. Nature, however, offers remarkable examples of organisms ...
Medical Xpress / Microproteins provide new playbook for Alzheimer's research
Scientists researching Alzheimer's disease and neurodegeneration have been playing a difficult game. Their scientific playbook has been limited by the available resources that, while capturing loads of genes, proteins and ...
Medical Xpress / Brain MRI surveillance without prophylactic cranial irradiation improves cognitive outcomes in small cell lung cancer
In the SWOG S1827 MAVERICK Phase III randomized trial, patients with small-cell lung cancer (SCLC) who underwent regular brain MRI surveillance without prophylactic cranial irradiation (PCI) had significantly better cognitive ...
Phys.org / A painting signed 'L daVinci': Analysis reveals Renaissance pigments and later alterations
Researchers at Uppsala University have analyzed the color pigments in a historical painting signed "L daVinci." Most of the pigments are consistent with materials used during the Renaissance, while a more recent pigment appears ...
Phys.org / Peptide position determines whether gold nanoparticles branch or stay spherical
The position of biomineralization peptides within liposomes can influence how gold nanoparticles grow, reports a research team from the Institute of Science Tokyo. Peptides localized at the membrane interface promote branched ...
Phys.org / Magnets could help quantum computers talk to each other, says researcher
Xufeng Zhang is using magnets to make computers more power efficient at the quantum level. The Northeastern professor of electrical and computer engineering recently published two papers highlighting small-scale magnetic ...
Phys.org / Blue light breaks long-standing chemistry rule, unlocking 3D drug building blocks
For more than a century, pharmaceutical companies have relied on flat structures called aromatic rings, which can help drugs bind to target sites in the body. They include benzene rings and other flat, nitrogen-containing ...
Medical Xpress / Four to six servings of whole grain per day lower risk factors for heart disease
Eating four to six servings of whole grains each day reduces several major risk factors for cardiovascular disease, according to a new study published in the European Heart Journal. The study is a systematic review and meta-analysis, ...
Phys.org / Rust prevention coating uses nanotech to self-repair and conquer corrosion
A single application of a "smart" self-repairing coating is being developed to dramatically extend rust protection for buildings, bridges, cars and other steel components.
