A new study published Feb. 24 in the journal Royal Society Open Science documents the earliest-known fossil evidence of primates. These creatures lived less than 150,000 years after the Cretaceous-Paleogene mass extinction event that killed off non-avian dinosaurs and saw the rise of mammals.
UCLA researchers found that patients’ decision-making about how and when to seek treatment for kidney stones was driven by logistical barriers and patients’ reluctance to risk exposure to COVID-19 in health care facilities.
But in the rapidly changing Arctic soundscape, where noise from industrial activities is predicted to dramatically increase in the next 15 years, bearded seals may need to adjust their calling behavior if they are going to be heard above the noise generated by ships and commercial activities.
Healthcare workers might not be so different from the general population in the factors that determine their risk of getting COVID-19. A new study led by Cedars-Sinai shows that healthcare workers are more likely to have antibodies to COVID-19 in their blood if they are African American or Latino or have hypertension.
A German-Polish research team has succeeded in creating a micrometer-sized space-time crystal consisting of magnons at room temperature. With the help of the scanning transmission X-ray microscope Maxymus at Bessy II at Helmholtz Zentrum Berlin, they were able to film the recurring periodic magnetization structure in a crystal.

In a paper recently presented at the 54th Hawaii International Conference on System Sciences, the research team wrote that, prior to the onset of the COVID-19 pandemic, “little attention had been paid to the possibility that a significant number of critical personnel in both the infrastructure and disaster response and recovery supply chains could be incapacitated or otherwise unavailable due to an ongoing pandemic.” Furthermore, their modeling suggests that “our current understanding of such compound extreme events is inadequate to the potential threat.”
The weight of isolation and loss of social connection caused by the COVID-19 pandemic has compounded existing psychosocial-emotional issues already experienced by adults who identify as sexual or gender minorities (SGM). And while many people globally and across the United States—regardless of their gender identity—are experiencing pandemic anxiety at some level, those who identify as SGM appear to have been disproportionally affected by the pandemic both physically and mentally.
Reports on variants of the coronavirus that causes COVID-19 have swept the news over the past few months, but what exactly is a virus variant?
Scientists at the Children’s Medical Center Research Institute at UT Southwestern (CRI) have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study, published in Nature, also shows that movement-induced stimulation is required for the maintenance of this niche, as well as the bone and immune-forming cells that it contains. Together, these findings identify a new way that exercise strengthens bones and immune function.
