| Coastal ecosystem being destabilized by climate change Posted: 10 Jan 2022 03:49 PM PST Ecological communities on the Oregon coast are being subtly destabilized by the pressures of climate change despite giving an appearance of stress resistance, new research shows. |
| Posted: 10 Jan 2022 03:48 PM PST Researchers report a new method for analyzing pyroptosis -- the process of cell death that is usually caused by infections and results in excess inflammation in the body -- and show that the process, long thought to be irreversible once initiated, can in fact be halted and controlled. The discovery means that scientists have a new way to study diseases that are related to malfunctioning cell death processes and infections that can be complicated by out-of-control inflammation. |
| Posted: 10 Jan 2022 03:48 PM PST Scientists suggest magnetite crystals that form inside specialized receptor cells of salmon and other animals may have roots in ancient genetic systems that were developed by bacteria and passed to animals long ago through evolutionary genetics. |
| Researchers discover fossil of new species of pangolin in Europe Posted: 10 Jan 2022 03:48 PM PST Deeper analysis of fossils from one of Eastern Europe's most significant paleontological sites has led to the discovery of a new species of pangolin, previously thought to have existed in Europe during the early Pleistocene but not confirmed until now. |
| Successful transplant of porcine heart into adult human with end-stage heart disease Posted: 10 Jan 2022 03:30 PM PST In a first-of-its-kind surgery, a 57-year-old patient with terminal heart disease received a successful transplant of a genetically-modified pig heart and is still doing well three days later. |
| The ‘surprisingly simple’ arithmetic of smell Posted: 10 Jan 2022 11:53 AM PST Researchers studying locusts have found that the presence of smell can be determined by simply adding and subtracting the presence of certain neurons. |
| Fishers facing pressure from wildfires, salvage logging Posted: 10 Jan 2022 11:52 AM PST The recovery of the fisher, a charismatic, long-tailed forest carnivore, will likely be hindered by the increasing frequency and intensity of future wildfires, new research indicates. |
| New study links gut fungi to intestinal inflammation in Crohn’s disease patients Posted: 10 Jan 2022 11:52 AM PST Results of a new study represent a step toward improving our understanding of Crohn's disease and the factors that cause its intestinal inflammation. |
| Unexpected benefits from food competitors Posted: 10 Jan 2022 08:41 AM PST A research team has found that gravid tobacco hawkmoths (Manduca sexta) show an unusual preference for Datura plants that are already infested with leaf beetles when laying their eggs. The beetles and their larvae actually compete with tobacco hornworms, the larvae of Manduca, for food. Plants infested by beetles change their odor profile and increase the production of the substance alpha-copaene, making them, however, more attractive to tobacco hawkmoths. Despite food competition, tobacco hornworms seem to benefit from their mothers' choice of such host plants because in the presence of beetles and their larvae they are better protected from parasitic wasps that avoid beetle-infested plants. The researchers were also able to identify the tobacco hawkmoths' olfactory receptor that controls this behavior. |
| How triclosan, found in many consumer products, is triggered to harm the gut Posted: 10 Jan 2022 07:32 AM PST Increasingly, research links triclosan, an antimicrobial found in thousands of consumer products, with the gut microbiome and gut inflammation. A new study looks at the potential for combating damage to the intestine. The findings suggest new approaches for improving the diagnosis, prevention and treatment of inflammatory bowel disease. |
| A crowning achievement in understanding head development Posted: 10 Jan 2022 07:32 AM PST To understand how cranial neural crest cells (CNCCs) help form many more body parts than the skull and facial skeleton, scientists from the lab of Gage Crump created a series of atlases over time to understand the molecular decisions by which CNCCs commit to forming specific tissues in developing zebrafish. The researchers labeled and tracked CNCCs throughout the lifetime of zebrafish. With the help of a new computational analysis they created, they identified genetic signs that point to the specific tissues CNCCs were destined to form. The researchers also identified many of the potential switches that allow CNCCs to form these very different cell types. |
| Cancer therapy using on-site synthesis of anticancer drugs Posted: 10 Jan 2022 07:32 AM PST Researchers have successfully treated cancer in mice using metal catalysts that assemble anticancer drugs together inside the body. This study is the first report of therapeutic in vivo synthetic chemistry being used to make anticancer substances where they are needed simply by injecting their ingredients through a vein. Because this technique avoids indiscriminate tissue damage, it is expected to have a significant impact on cancer treatment. |
| New bacteria in UK waters as temperatures rise Posted: 10 Jan 2022 07:32 AM PST Rising temperatures are causing a 'growing diversity' of Vibrio bacteria in the sea around the UK, new research shows. |
