Auf dem Prüfstand: Tausende Klimaschutzmaßnahmen wurden bisher in verschiedenen Ländern umgesetzt – aber nur 63 dieser Maßnahmen trugen in größerem Umfang zur Reduktion der globalen Treibhausgas-Emissionen bei, wie eine Auswertung ergab. Der Erfolg dieser Klimapolitik beruht meist auf einer Kombination von...

A new study published in Nature Microbiology has pioneered the use of a single-celled parasite, Toxoplasma gondii, to inject therapeutic proteins into brain cells. The brain is very picky about what it lets in, including many drugs, which limits treatment options for neurological conditions....

By using brain organoids derived from autistic children’s stem cells, researchers uncovered distinct neural growth patterns, potentially guiding personalized treatments and diagnoses.

Details of the model, which is called RTDetective, are provided in a new paper published in Nature Genetics titled, “Genome-scale quantification and prediction of pathogenic stop codon readthrough by small molecules.” Its developers believe that the tool could be helpful in the design, development, and efficacy of clinical...

The study found that MS patients had 50% less amyloid plaque accumulation, a key indicator of Alzheimer’s, compared to non-MS individuals. This connection between MS and reduced Alzheimer’s risk highlights potential immune-related mechanisms that may be leveraged for therapeutic strategies....

The rapid growth of artificial intelligence (AI) offers immense potential for scientific advancements, but it also raises ethical concerns. AI systems can analyse vast data sets, detect patterns, optimize resource use and generate hypotheses. And they have the potential to help address global challenges including climate change,...

The Neolithic farmers and herders who built a massive stone chamber in southern Spain nearly 6,000 years ago possessed a good rudimentary grasp of physics, geometry, geology and architectural principles, finds a detailed study of the site....

Led by Ludwig Lausanne’s Ping-Chih Ho and Alessio Bevilacqua and published in the current issue of Science Immunology, the study identifies PPARβ/δ, a master regulator of gene expression, as that essential molecular switch. Ho, Bevilacqua and their colleagues also show that the switch’s dysfunction compromises T cell...

People tend to have one of two reactions to tarantulas: a sharp, primal terror that author David Foster Wallace described as “the howling fantods,” or the kind of attachment more commonly associated with kittens and puppies. People are just not indifferent to tarantulas....

A study found that nondeceptive placebos, or placebos given with people fully knowing they are placebos, effectively manage stress – even when the placebos are administered remotely.

Brain-computer interfaces are a groundbreaking technology that can help paralyzed people regain functions they’ve lost, like moving a hand. These devices record signals from the brain and decipher the user’s intended action, bypassing damaged or degraded nerves that would normally transmit those brain signals to control...

A recent study examining the sleep patterns of healthy men and women who participated in a parabolic flight—an experience that exposes individuals to brief periods of microgravity and hypergravity—revealed surprising results. According to actigraphy, a method used to objectively measure sleep by tracking movement,...

Researchers have discovered a “spatial grammar” in DNA that redefines the role of transcription factors in gene regulation, influencing our understanding of genetic variations and disease....
