Assumptions that tropical forest canopies protect from the effects of climate change are unfounded, say researchers. Crucial strongholds for biodiversity are under threat as temperatures are rising in tropical forests, the world’s most diverse terrestrial ecosystems, a new study reveals.

Dr. Anthony Fauci is facing heated questioning from Republican lawmakers about the origins of the COVID-19 pandemic. The top U.S. infectious disease expert until 2022, Fauci was grilled by the House panel behind closed doors in January. On Monday, they’re questioning him again, in public and on camera. The Republican-led subcommittee has spent over a…

Methane is a greenhouse gas about 25 times more potent than carbon dioxide. At low temperatures and high pressure, it combines with water to form methane hydrate, an ice-like solid of which huge deposits exist under the seafloor.

Under certain conditions, some algae are able to produce hydrogen—a much sought-after green energy source. Its production takes place in the unique catalytic center of the unicellular algae and is only possible if certain cofactors of the relevant proteins are present.

The Celtic culture of the pre-Roman Iron Age in Western and Central Europe has left numerous traces to this day, not least in the form of enormous burial mounds and spectacular archaeological artifacts. Despite this rich legacy, much about this civilization remains hidden from us. The Celtic culture of the pre-Roman Iron Age in Western and…
