Researchers have discovered a key protein, AP2-G, essential for the development of male and female sexual forms of the malaria parasite. The protein triggers the production of gametocytes, which are infectious to mosquitos, offering clues for identifying transmission mechanisms.
A new study published in Nature Climate Change found no link between warmer winters and reduced excess winter death rates in the UK. Instead, flu activity was identified as the main cause of year-to-year variation in winter mortality.
Researchers at BRIC, University of Copenhagen, have developed a new technology that can isolate histones and follow dynamic duplication processes in cells. The technology has identified 100 new molecular components involved in chromatin duplication and maintenance of cell memory.
Researchers at Uppsala University have challenged the established model for gene regulation by directly measuring transcription factor concentrations in living cells. They found small but significant differences between measurements, opening up new possibilities for understanding gene regulation.
A team led by Robert Linhardt and Jian Liu created a synthetic form of low-molecular-weight heparin, which can be reversed in cases of overdose and is safer for patients with poor kidney function. The new drug is also cost-effective and has improved properties compared to the animal-derived alternative.
Scientists discovered that key characteristics of flight, such as body size and forelimb length, evolved simultaneously in a group of dinosaurs. These findings suggest that birds arose through multiple evolutionary steps, with powered flight emerging later.
Researchers have discovered a novel immunological mechanism that regulates B lymphocytes to fight encapsulated bacteria, clearing the path for more efficient vaccines. This discovery improves our understanding of the immune system's protection against infections.
Researchers discovered a 'microbial Pompeii' in ancient dental calculus, revealing opportunistic pathogens and periodontal disease-causing bacteria. The study also recovered dietary DNA, providing insights into ancient diets and the origins of antibiotic resistance.
Researchers successfully increased photosynthetic rate by 30% and turned sugarcane into an oil-producing crop. The team hopes to integrate these attributes into sugarcane to make it more productive with more photosynthesis and cold-tolerant.
A study published in Nature identified the CA2 region of the hippocampus as crucial for social memory, a function impaired in individuals with autism, schizophrenia, and bipolar disorder. The findings suggest that targeting the CA2 region could lead to new therapeutic approaches for treating these brain disorders.
Researchers have developed a groundbreaking MRI technique that can visualize metabolic changes in the body's cells. This breakthrough could lead to earlier diagnoses of diseases such as diabetes and cancer. The hyperpolarization method provides a fingerprint of cellular activity, allowing for real-time monitoring of disease progression.
Scientists created nanoparticles that selectively bind to abnormal immune cells causing inflammation, allowing anti-inflammatory drugs to reach them while leaving healthy ones untouched. This targeted approach shows promise for treating inflammatory diseases with fewer side effects.
Researchers from the Niels Bohr Institute detected a stream of stars in Andromeda II, revealing a remnant of a merged dwarf galaxy. The findings provide insight into the rare event of low-mass galaxy mergers, which are expected during galaxy formation.
A new study using a tiny fragment of zircon extracted from Australia's Jack Hills region confirms the Earth's crust formed at least 4.4 billion years ago, providing evidence for a 'cool early Earth' theory. The findings suggest temperatures were low enough for liquid water and oceans to form.
Researchers at Gladstone Institutes and UCSF have made a breakthrough in regenerative medicine by transforming skin cells into mature, fully functioning liver cells. The new method offers hope for treating liver failure and could serve as an alternative to liver transplants.
Researchers identified a polio-like syndrome in five California children over a year, highlighting the possibility of an emerging infectious polio-like syndrome. The children experienced paralysis affecting one or more limbs with abnormal MRI scans, and two tested positive for enterovirus-68.
