Phys.org / Ancient mosquitoes developed a taste for early hominins, research reveals
The preference of some mosquitoes in the Anopheles leucosphyrus (Leucosphyrus) group—including those that transmit malaria—for feeding on humans may have evolved in response to the arrival of early hominins in Southeast ...
Phys.org / How oxygen enriched Earth's atmosphere 2.5 billion years ago
Cyanobacteria, as they still exist today, were the first organisms to carry out photosynthesis and release oxygen. Produced in primeval oceans about 2.5 billion years ago, this oxygen accumulated in Earth's atmosphere on ...
Medical Xpress / A universal 'instruction manual' helps immune cells protect our organs
Researchers at the University of Liège have identified a key genetic regulator that enables macrophages to reach full maturity and preserve the health of our organs. The MafB factor, a veritable "molecular switch," activates ...
Phys.org / ALMA explores giant molecular clouds in nearby galaxy NGC 1387
An international team of astronomers has employed the Atacama Large Millimeter/submillimeter Array (ALMA) to investigate molecular gas in a nearby galaxy known as NGC 1387. Results of the observational campaign, published ...
Medical Xpress / Women show greater tau buildup and faster cognitive decline than men in Alzheimer's
Tau proteins act like the brain's maintenance crew, helping maintain the structure and proper function of brain cells. In neurodegenerative diseases such as Alzheimer's, the tau proteins can form tangles that disrupt normal ...
Phys.org / Atomic precision unlocks smarter oxygen reduction catalysts
Tiny changes at the atomic scale can determine the future of clean energy. In a new study, Tohoku University researchers have revealed how the precise coordination environment surrounding a single cobalt atom dramatically ...
Medical Xpress / At-home gut health tests yield contradictory results, study suggests
Results and health assessments from gut microbiome home-testing kits vary whether they are produced by the same or different manufacturers. The findings on testing kits from seven providers, published in Communications Biology, ...
Phys.org / Will melting glaciers slow climate change? A prevailing theory is on shaky ground
For scientists who study the Southern Ocean, a long-standing silver lining in the gloomy forecast of climate change has been the theory of iron fertilization. As temperatures rise and glaciers in Antarctica melt, ice-trapped ...
Phys.org / Nanochannel method makes ion membranes twice as strong for clean energy
Researchers have found a way to fabricate film-thin membranes imbued with super strength that could extend the durability of decarbonization technologies. Chemical engineers at The University of Queensland are harnessing ...
Phys.org / Endangered giant clam feeding strategies could determine species' future survival
Giant clams (Tridacna gigas), members of the family Tridacnidae and among the most striking inhabitants of tropical coral reefs, are being driven toward extinction. Over-harvesting for jewelry, the aquarium trade, and food, ...
Medical Xpress / CRISPR-based platform pinpoints drivers of leukemia in patient cells
A new CRISPR-based tool that is directly used on patients' cancer cells can identify genes and regulatory elements driving acute myeloid leukemia (AML), an aggressive blood cancer affecting the bone marrow and blood. This ...
Medical Xpress / How stepping into nature affects the brain
Spending time in nature, even briefly, triggers changes in the brain that calm stress, restore attention, and quiet mental clutter, a new study has found. Researchers at McGill University and colleagues at Adolfo Ibáñez ...
