A brewing "super" El Nino cycle is poised to unleash heat waves, floods and drought worldwide, with the effects amplified by long-term human-caused climate change.
Researchers at Baylor College of Medicine and the Texas Department of State Health Services have reported a likely case of soft tick-borne relapsing fever (STRF) in an Austin-area resident. Now, they highlight the growing risk of exposure to infected ticks in urban and residential settings. The study appeared in Open Forum Infectious Diseases.
Xenophagocytosis is a natural immune process that limits interspecies organ generation by eliminating living donor cells, researchers at the Institute of Science Tokyo, Japan, report. By uncovering how embryonic macrophages eliminate living donor cells, the researchers developed strategies to block this response. Using this strategy, they significantly improved donor cell survival and the generation of rat pancreas in mice, bringing us one step closer to producing transplantable human organs in animals.
Koç University researchers have developed a conservation method that combines photogrammetry, digital modeling, 3D printing and embedded sensors to replace missing sections of archaeological amphorae. The customized fills can also monitor environmental and physical changes affecting the artifacts, offering a systematic approach to their conservation and long-term preservation.
IBM and researchers from the University of Chicago announced a demonstration in quantum computing that meets the fundamental criteria for "quantum advantage"—the point where quantum computers can be confirmed to have outperformed classical computers on trusted computations.
A team of Brazilian researchers discovered the first direct evidence that goethite—the mineral responsible for the brown color of soils—can withstand extreme pressures and temperatures all the way to the planet's interior inside a diamond just 3 millimeters (0.1 inch) long, within a microscopic impurity. Goethite forms in soil and on the ocean floor from iron-rich minerals in the presence of water. It incorporates some of these water molecules into its mineral structure. The study suggests that goethite may transport and release water into a region known as the lower mantle.
Two plants that cause neurotoxicity and paralysis in the tiniest doses are also known to counter pain, malaria, cancer and pests. For the first time, researchers discovered a way to recreate these powerful compounds in the lab, helping lead the way to improved, naturally sourced therapeutics.
Ripley, a medium-sized dog with a strong prey drive, curiously approached Brian, a large western diamondback rattlesnake, until she got a quick zap on the neck meant to simulate a venomous viper's bite.
Our sun constantly releases a stream of high-speed charged particles, known as the solar wind. Unlike Earth, Mars does not have a strong global magnetic field to shield its atmosphere from this flow. As a result, the solar wind can interact directly with Mars' upper atmosphere and gradually strip atmospheric particles into space.
The UK is bouncing from one type of extreme weather to another this year. This is climate whiplash. Caused by changes in the fast-moving body of air high in the atmosphere called the jet stream, climate whiplash has become more likely with climate change. These constant shifts in extreme weather make it challenging to build resilience.
