| Proteins that predict future dementia, Alzheimer's risk, identified Posted: 17 May 2021 11:47 AM PDT The development of dementia late in life is associated with abnormal blood levels of dozens of proteins up to five years earlier, according to a new study. Most of these proteins were not known to be linked to dementia before, suggesting new targets for prevention therapies. |
| New evidence of how and when the Milky Way came together Posted: 17 May 2021 09:49 AM PDT New research provides the best evidence to date into the timing of how our early Milky Way came together, including the merger with a key satellite galaxy. Using relatively new methods in astronomy, the researchers were able to identify the most precise ages currently possible for a sample of about a hundred red giant stars in the galaxy. |
| Rare COVID-19 response in children explained Posted: 17 May 2021 09:47 AM PDT One of the enduring mysteries of the COVID-19 pandemic is why most children tend to experience fewer symptoms than adults after infection with the coronavirus. The immune system response that occurs in the rare cases in which children experience life-threatening reactions after infection may offer an important insight, a new study suggests. |
| Harvesting light like nature does Posted: 15 May 2021 06:11 AM PDT Inspired by nature, researchers have created a novel material capable of capturing light energy. This material provides a highly efficient artificial light-harvesting system with potential applications in photovoltaics and bioimaging. |
| Mammals can use their intestines to breathe Posted: 14 May 2021 10:42 AM PDT Rodents and pigs share with certain aquatic organisms the ability to use their intestines for respiration, a new study finds. The researchers demonstrated that the delivery of oxygen gas or oxygenated liquid through the rectum provided vital rescue to two mammalian models of respiratory failure. |
