For decades, scientists assumed that the first modern humans to reach Europe, about 45,000 years ago, quickly evolved pale skin to adapt to the faint sunlight of the region. Logic seemed simple: lighter skin allows more ultraviolet light to penetrate, helping the…
Of the weatherREALISM By Lueken Linnea A recent CNN article, “How a ‘fart from cow’ could help address climate change“, Discusss a vaccine in development to cows to reduce the amount of methane produced by their digestive processes. The hope is that the vaccine significantly reduces cattle emissions, thus slowing climate change. It will not…
In recent months, I have had the honor of representing AGU in two key global events: the UN Biodiversity Conference 2024 in Cali, Colombia (CBD16) and the UN climate change conference in Baku, Azerbaijan (COP29) . Reflecting on these meetings, it is clear that the results do not reach the urgency required by biodiversity and…
More than five billion people worldwide lack reliable access to medical oxygen, a crucial resource to treat various health conditions. A new report underlines the need for national oxygen plans, greater financing and stronger public public collaboration. While pandemic related investments helped, many regions still fight due to infrastructure shortage and equipment. Filling the Global…

But, in fact, there are many more phases, some of which predicted to exist at high temperature and pressure, are so strange that they are known as exotic. The avant-garde neutrons spectrometers…
A study finds that 65.8% of adults surveyed had little confidence in their medical care system to use artificial intelligence in a responsible manner and 57.7% had little confidence in their medical care systems to ensure that an AI tool will damage them. The research letter was published in Open Jama Network. Adults who had…
Solar radio explosions are an indirect firm of accelerated electrons of the solar atmosphere. These rapid electrons generate Langmuir waves as they propagate through a decreasing plasma density and, ultimately, lead to bright broadband radio emissions with a quick frequency drift characteristic in dynamic spectra. Density turbulence in plasma can modulate this process, producing fine…
Scientists often use “epigenetic watches” to measure biological aging, but what makes these watches work is not completely understood. Now, scientists have discovered a clue: watches are synchronized with random mutations that arise in DNA as we age. For a long time it is known that, about human life, mutations accumulate in the DNA of…
As Ph.D. Candidate in the Department of Earth Sciences and the Environment at the Lamont-Doherty Earth Observatory, Caroline Jureg is currently investigating how the climate affects forest fires in the west of the United States, pressing in front of the recent fires of Angels and catastrophic. She uses satellite data, large data sets and statistical…
The egg nebula, as it has been photographed here by Hubble, is a preplanetary nebula, since its external layers have not yet heated at sufficient temperatures by the central and contracting star to completely ionize. Many of the giant stars visible today will evolve towards a nebula such as it is before throwing their external…
