In contrast to what many believe, Swedish men and women with higher incomes have more children, new research from Stockholm University shows. This pattern is particularly clear for men and grows stronger over time: the more money, the more children. But after four children, things change. Unlike previous studies, where researchers looked at people's income at certain points in life, […]

When an infant cries, parents frequently wonder whether they should soothe the baby or let the baby calm itself down. If they respond to every sob, won’t the baby cry more? Isn’t that spoiling the baby? I hear these questions a lot as a professor of child development and family science. The notion of spoiling a baby remains common in […]

In a recent study published in Nature Medicine, researchers systematically investigated the genetic makeup of nearly 20,000 women and men in terms of >900 metabolites. Study: Rare and common genetic determinants of metabolic individuality and their effects on human health.

A recent opinion piece published in PNAS discussed the sequence of events concerning the coronavirus disease 2019 (COVID-19) pandemic to provide evidence against the alleged leak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the Ebola virus from viral research laboratories in Wuhan, China, and West Africa, respectively. Study: The evidence remains clear: SARS-CoV-2 emerged via the wildlife trade. […]

(Reuters) – A federal judge in Texas ruled on Friday that President Joe Biden’s administration had wrongly interpreted an Obamacare provision as barring health care providers from discriminating against gay and transgender people. U.S. District Judge Matthew Kacsmaryk in Amarillo ruled that a landmark U.S. Supreme Court decision in 2020 holding that a law barring workplace discrimination protects gay and […]

For many patients with a condition that often precedes multiple myeloma, early treatment can slow or delay the progression to myeloma. In a new study, investigators at Dana-Farber Cancer Institute demonstrate that changes in immune system cells can indicate which patients with high-risk “smoldering” myeloma are likely to progress to myeloma and which will benefit the most from treatment. The […]

Editor’s note: Find the latest COVID-19 news and guidance in Medscape’s Coronavirus Resource Center. Getting COVID-19 a second time doubles a person’s chance of dying and triples the likelihood of being hospitalized, a new study found. Vaccination and booster status did not improve survival or hospitalization rates among people who were infected more than once. “Reinfection with COVID-19 increases the […]

In a recent study published in Nature Microbiology, researchers investigated the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in white-tailed deer. Study: Divergent SARS-CoV-2 variant emerges in white-tailed deer with deer-to-human transmission. Image Credit: Holly Kuchera/Shutterstock Background Wildlife reservoirs of viruses with a broad host range can facilitate the emergence of human-infecting viral variants. There is phylogenomic evidence […]

In a recent study published in the Nature journal, researchers assessed the impact of spatiotemporal epidural electrical stimulation (EES) on individuals suffering from chronic spinal cord damage. The lumbar spinal cord contains the neurons that regulate the activity of walking. To activate these neurons responsible for walking, the brain transmits orders through descending pathways from the brainstem. An acute spinal […]

A decades-long effort to lower the stillbirth rate in the United States has stalled, as has progress in closing a persistent gap in excess stillbirths experienced by Black women compared with White women, according to a Rutgers-led study. "Over the last 40 years, we have reduced certain risk factors for stillbirth, such as smoking and alcohol use before and during […]
