Antidepressant use in pregnancy tied to affective disorders in offspring; no causal link

Antidepressants are usually given as a first-line treatment, including during pregnancy, either to prevent the recurrence of depression, or as acute treatment in newly depressed patients. Antidepressant use during pregnancy is widespread and since antidepressants cross the placenta and the blood-brain barrier, concern exists about potential long-term effects of intrauterine antidepressant exposure in the unborn child.

Formatted as a microsite, the online celebration recognizes and shares the accomplishments of the 2021 Vilcek Foundation Prizewinners in lieu of the Vilcek Foundation s annual gala. Awarded annually, the Vilcek Foundation Prizes celebrate the value and importance of immigration by recognizing the outstanding achievements of foreign-born individuals in the United States. In 2021, the Vilcek Foundation Prizes are awarded in Biomedical Science, in Filmmaking, and for Excellence in Public Service.

An artful study of cellular development in leaves

While developmental biologists have long researched this fundamental question, Stanford University biologist and HHMI investigator Dominique Bergmann s recent work on the plant Arabidopsis thaliana has uncovered surprising answers. In a new study, published April 5 in Developmental Cell, led by Bergmann and postdoctoral scholar Camila Lopez-Anido, researchers used single-cell RNA sequencing technologies to track genetic activity in nearly 20,000 cells as they formed the surface and inner parts of an Arabidopsis leaf. Through this highly detailed technique, the researchers captured transient and rare cell states and found a surprising abundance

Connecting the dots between engagement and learning

 E-Mail We ve all heard the adage, If at first you don t succeed, try, try again, but new research from Carnegie Mellon University and the University of Pittsburgh finds that it isn t all about repetition. Rather, internal states like engagement can also have an impact on learning. The collaborative research, published in Nature Neuroscience, examined how changes in internal states, such as arousal, attention, motivation, and engagement can affect the learning process using brain-computer interface (BCI) technology. Findings suggest that changes in internal states can systematically influence how behavior improves with learning, thus paving the way for more effective methods to teach people skills quickly, and to a higher level of proficiency.

Scientists create model of an early human embryo from skin cells

Credit: Monash University AUSTRALIAN - LED INTERNATIONAL RESEARCH TEAM GENERATES THE FIRST MODEL OF EARLY HUMAN EMBRYOS FROM SKIN CELLS In a discovery that will revolutionize research into the causes of early miscarriage, infertility and the study of early human development - an international team of scientists led by Monash University in Melbourne, Australia has generated a model of a human embryo from skin cells. The team, led by Professor Jose Polo, has successfully reprogrammed these fibroblasts or skin cells into a 3-dimensional cellular structure that is morphologically and molecularly similar to human blastocysts. Called iBlastoids, these can be used to model the biology of early human embryos in the laboratory.
