Biomarkers that predict preeclampsia risk

In a study of pregnant women in the United States, investigators found that a specific imbalance of two placental proteins could predict which women were at risk of developing a severe form of preeclampsia, a life-threatening blood pressure disorder.

Using SNAP benefits can help your memory, study finds

Eligible older adults who participate in the Supplemental Nutrition Assistance Program (SNAP) in the United States may have slower memory decline than eligible people who do not participate, according to a new study. Researchers found that those who used SNAP had about two fewer years of cognitive aging over a 10-year period compared with those who didn't use SNAP.

Pandemic led to 7.5 percent decrease in 2020 U.S. energy consumption

Total energy consumption decreased 7.5 percent nationwide in 2020 compared with 2019 as the COVID-19 pandemic led to lockdowns, business closures and employees working from home, according to a new study. The research is the first to quantify the effects of pandemic disruptions on energy consumption trends across all 50 states and the District of Columbia.

Identification of the cells responsible for colon cancer relapse

Researchers report the discovery of the population of residual tumor cells responsible for the recurrence of colorectal cancer in other organs after removal of the primary tumor. The study shows that early immunotherapy, before surgery, can eliminate these cells before they have started to develop a metastasis, and thus prevent relapse of the disease. The work paves the way for the development of...

Early diagnosis tool for childhood kidney disease

Early diagnosis of chronic kidney disease (CKD) is key to managing progression of the disease. A new technique analyzing urine extracellular vesicles (uEVs) -- cell-derived nanoscale spherical structures involved in multiple biological functions -- in urine samples identifies changes in the kidneys earlier than conventional methods and can also predict renal function decline.

Trust in experts, media literacy connected to COVID-19 vaccine intention

An early pandemic survey found that respondents' intentions to receive COVID-19 vaccines were linked more to their media literacy and opinion of health experts than knowledge of the virus or previous vaccination behavior. In the study, researchers also found that for respondents who had recently refused a flu vaccine, higher COVID-19 knowledge actually correlated with lower future vaccine...

Temperature, nearby species could affect avian flu transmission in migrating birds

Finding a turkey this holiday season could be difficult because of avian flu outbreaks on farms. Migratory wild birds could be to blame for transmitting the virus to commercial flocks, but no one has looked closely at this wandering population until now. Researchers now report that cooler temperatures and certain species gathering in the same winter habitat could increase the circulation of H7 and...

Monoclonal antibodies preserve stem cells in mouse brains, bring promise for future studies

A new approach to stem cell therapy that uses antibodies instead of traditional immunosuppressant drugs robustly preserves cells in mouse brains and has potential to fast-track trials in humans, a new study suggests. Suppression with monoclonal antibodies enabled long-term survival of human stem cell transplants in mouse brains for at least six to eight months, while the cell grafts did not...

New hope for patients with severe bone loss

An innovative technology has been developed to enable bone regeneration to correct large bone defects by means of a special hydrogel. Following successful tests in an animal model, the researchers now plan to move forward to clinical trials.

The X chromosome is silenced in some male cancers

Cancer cells acquire genetic anomalies that allow them to grow and proliferate unchecked. Researchers have now found another difference between cancer cells and normal cells: the X chromosome, typically only inactivated in XX female cells, can be inactivated across different male-derived cancers.
