Climate change is impacting major air currents that control extreme weather events, helping to power natural disasters like heat waves, droughts, wildfires, and floods in North America, Europe, and Asia, according to a new study published in the journal Scientific Reports.

Drugs containing gold have been used for centuries to treat conditions like rheumatoid arthritis. In addition, they might be effective against cancer and HIV. One mechanism by which they work could occur because gold ions force the zinc ions out of zinc fingers—looped, nucleic acid binding protein domains. American researchers have characterized such “gold fingers” using ion mobility mass spectrometry. As reported in the journal Angewandte Chemie, they identified the exact gold binding sites.

A vicious cycle of climate change, cattle diet and rising methane has been revealed in a new scientific study: as temperatures rise, forage plants get tougher and harder to digest, and cause more methane to be produced in bovine stomachs. And with cattle numbers rising and methane 85 times more powerful a greenhouse gas over 20 years, that spells trouble.

Unprecedented summer warmth and flooding, forest fires, drought and torrential rain — extreme weather events are occurring more and more often, but now an international team of climate scientists has found a connection between many extreme weather events and the impact climate change is having on the jet stream.

Many cancer patients struggle with the adverse effects of chemotherapy, still the most prescribed cancer treatment. For patients with pancreatic cancer and other aggressive cancers, the forecast is more grim: there is no known effective therapy.
