Scientists play a vital role in serving communities by deepening our understanding of the world and driving advances that improve public health, safeguard the environment, improve safety, and more. However, recent Administration policies are putting these contributions at risk, threatening the ability of America’s scientists to carry out this critical work. Scientists are not standing…
AI can detect cancer, but it can also detect who you are, and that’s important. A new study finds that artificial intelligence systems used to diagnose cancer from pathology slides do not work the same for all patients, and accuracy varies across race, gender and age groups. Researchers discovered three main reasons behind this […]…
Rock samples that formed about 60 million years ago and were collected from far below the ocean surface have helped scientists understand how large amounts of carbon dioxide can remain locked up for extremely long periods. These samples show that CO2 It is trapped between layers of lava debris that accumulate on the seabed. Researchers…
Polarization measurements of solar radio emissions are key diagnostics of coronal plasma, magnetic fields, and propagation effects, and can provide additional constraints on emission mechanisms. At meter wavelengths, circular polarization (CP) has long been exploited in solar radio studies, while linear polarization (LP) was assumed to be absent. This view arose from the expectation that…
About 3 billion years ago, an unfortunate star became caught in a twisting tug-of-war between two gigantic black holes, and now we’re seeing the faint screams of X-rays emanating from this violent event. If confirmed, it could be the most distant episode of two black holes attacking a star ever seen. An international team of…
A recent study of Letters on Earth and Planetary Sciences is the first to directly link earthquakes to climate change-induced glacier melt. Scientists analyzed 15 years of seismic activity on the Grandes Jorasses, a peak that is part of the Mont Blanc massif between Italy and France, to better understand this association. This massif is…
These massive and supermassive black holes have baffled astronomers for decades. At last, we have finally discovered how they are formed. Continue reading Start with a bang! » #Supermassive #black #holes #appeared #stars #ancient #galaxies
Under the Paris agreement, each country must provide a reliable inventory of greenhouse gas emissions to the United Nations Framework Convention on Climate Change (UNFCCC) using guidance provided by the Intergovernmental Panel on Climate Change (IPCC). Under the Enhanced Transparency Framework, each country must apply the 2006 IPCC guidelines to complete greenhouse gas inventories. The…
Background Snakebite envenomings (SBE) are an important and neglected health problem due to their frequency and potential for serious clinical outcomes. Envenomations can cause local and systemic complications, depending on the species of snake, the amount of venom injected, comorbidities, timing and use of antivenin, and access to medical care. Systemic effects can be fatal…
A healthy man in his 50s suffered a stroke after drinking eight energy drinks every day, a habit that raised his blood pressure to a dangerously high range. The incident, described in BMJ Case Reportsis prompting renewed concern about how excessive caffeine consumption can harm the cardiovascular system. The patient arrived at the hospital with…
