Astronomers explain origin of elusive ultradiffuse galaxies: How very faint dwarf galaxies are born
As their name suggests, ultradiffuse galaxies, or UDGs, are dwarf galaxies whose stars are spread out over a vast region, resulting in extremely low surface brightness, making them very difficult to detect. Several questions about UDGs remain unanswered: How did these dwarfs end up so extended? Are their dark matter halos — the halos of […]
Making methane from CO2: Carbon capture grows more affordable: Methane made from CO2 and renewable hydrogen offers a new path toward cheaper carbon capture
In their ongoing effort to make carbon capture more affordable, researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a method to convert captured carbon dioxide (CO2) into methane, the primary component of natural gas. By streamlining a longstanding process in which CO2 is converted to methane, the researchers’ new method reduces […]
Researchers discover connection between brain’s opioid system and eating behavior
Brain regulation of feeding behavior traits has remained incompletely understood. In their latest study, researchers at the Turku PET Centre, Finland, discovered a connection between the function of the opioid system and food craving triggered by appetitive external stimuli. Animal studies have established that the brain’s opioid and endocannabinoid systems are important in regulating eating […]
Watercooler parts could be a source of organophosphate ester exposure
Watercoolers have become a staple in homes, offices and schools, but their tanks and parts are made of materials that could release unwanted or potentially harmful compounds into drinking water. In a preliminary study, researchers in ACS’ Environmental Science & Technology Letters report that organophosphate esters (OPEs) were found in water dispensed from these systems, […]
One in two pregnancies are affected by iron deficiency, yet many women don’t get a simple screening test to check
Half of pregnant women who had a simple blood test to check their iron stores had low iron levels, and one in four had severe iron deficiency, according to a paper published today in the journal Blood Advances. But despite how common iron deficiency is, 40% of pregnant women in this large regional study never […]
Mom’s Obesity During Pregnancy Linked to Colon Cancer in Offspring
Overweight and obesity in mothers during pregnancy increased the risk for colorectal cancer (CRC) in their children later on in life, according to a population-based study. Compared with underweight/healthy weight during pregnancy, both obesity and overweight were associated with increased risk of CRC in offspring (adjusted HR 2.51, 95% CI 1.05-6.02 and adjusted HR 2.12, […]
Humans managed shellfish and their predators for millennia
Due to their protected status, sea otter populations have rebounded across the Pacific Northwest Coast following their near elimination during the historic maritime fur trade. But the recovery of these shellfish predators and the federal laws now protecting them challenge local Indigenous communities who hold constitutionally protected rights to harvest those same shellfish but who […]

UNMC Mourns Surgeon Killed in Plane Crash
The University of Nebraska Medical Center (UNMC) in Omaha is mourning the tragic loss of one of their own. James Edney, MD, a professor emeritus in the department of surgery and former chief of the division of surgical oncology, died August 7 in a small plane crash in Minnesota, the medical school announced, citing a […]
AAN Issues Formal Position Statement on COVID-19 Vaccine
Based on existing evidence, neurologists should recommend COVID-19 vaccination to their patients, a newly released American Academy of Neurology (AAN) paper said. “Barring the rare circumstance of an absolute contraindication to available vaccine formulations, it is the American Academy of Neurology’s formal position that eligible patients should be offered the COVID-19 vaccine,” wrote Elisabeth Marsh, […]
