Published Human embryo-like models created from stem cells to understand earliest stages of human development (via sciencedaily.com) Original source
Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why and how pregnancies fail.
Published Lean body mass, age linked with alcohol elimination rates in women (via sciencedaily.com) Original source
Research links women's lean body mass with how quickly they eliminate alcohol from their system. Women with obesity and those who are older eliminate alcohol from their bloodstreams faster than those of normal weight and those who are younger.
Published Ketone supplements worsen performance in trained endurance athletes, researchers find (via sciencedaily.com) Original source
Kinesiologists at McMaster University have found ketone supplements, used by some athletes hoping to cross the finish line faster, may in fact worsen performance. The new study tackles contradictory research findings related to the effectiveness of ketone supplements, which have gained popularity among athletes seeking a competitive advantage.
Published One in five women become pregnant naturally after having a baby conceived with IVF (via sciencedaily.com) Original source
New research analyzed data from 11 studies of over 5,000 women around the world between 1980 and 2021, to evaluate how common it is to get pregnant naturally after having a baby conceived by fertility treatment. Around 20% of women who needed fertility treatment, such as IVF, to conceive their first child are likely to get pregnant naturally in the future, finds a new study.
Published Scientists discover new embryonic cell type that self-destructs to protect the developing embryo (via sciencedaily.com) Original source
Scientists have uncovered a new quality control system that removes damaged cells from early developing embryos.
Published New study gives clues on why exercise helps with inflammation (via sciencedaily.com) Original source
Researchers have long known that moderate exercise has a beneficial impact on the body's response to inflammation, but what's been less understood is why. New research done on a mouse model suggests that the answers may lie at the production level of macrophages -- white blood cells responsible for killing off infections, healing injury and otherwise acting as first responders in the body.
Published Pregnancy hormone repairs myelin damage in MS mouse model (via sciencedaily.com) Original source
A new study has identified a treatment that could repair myelin in the cortex, undoing some of the damage caused by MS.
Published Technique restores healthy bacterial balance in C-section babies (via sciencedaily.com) Original source
Newborns delivered by cesarean section who are swabbed with the vaginal fluid of their mothers after birth have beneficial bacteria restored to their skin surface and stools, according to a new study. In the first randomized study of its kind, a team of researchers found the process, known as vaginal seeding, definitively engrafted new strains of maternal bacteria in the babies' bodies.
Published New diagnostic finds intact sperm in infertile men (via sciencedaily.com) Original source
Researchers develop new diagnostic tool to visualize protein biomarkers of well-developed sperm to determine if surgical sperm extraction may be successful for certain infertile men.
Published Taurine may be a key to longer and healthier life (via sciencedaily.com) Original source
A study finds that deficiency of taurine, a molecule produced in our bodies, drives aging, and taurine supplements can improve health and increase lifespan in animals.
Published Exposure to 'forever chemicals' during pregnancy linked to increased risk of obesity in kids (via sciencedaily.com) Original source
Exposure to per- and polyfluoroalkyl substances (PFAS) during pregnancy was linked to slightly higher body mass indices and an increased risk of obesity in children, according to a new study.
Published The fast and the fibrous: Developing the muscles you need for speed (via sciencedaily.com) Original source
Researchers have identified the role of the large Maf transcription factor family in regulating fast twitch muscle fibers. A mouse model lacking Maf expression in the skeletal muscles exhibited a significant loss of type IIb myofibers, a subtype of fast twitch fibers. Overexpression of large Mafs promoted type IIb muscle fiber induction. The large Maf family may represent potential targets for developing treatments for muscular disorders involving fast twitch fibers.
Published Running throughout middle age keeps 'old' adult-born neurons 'wired' (via sciencedaily.com) Original source
A new study provides novel insight into the benefits of exercise, which should motivate adults to keep moving throughout their lifetime, especially during middle age. Long-term exercise profoundly benefits the aging brain and may prevent aging-related memory function decline by increasing the survival and modifying the network of the adult-born neurons born during early adulthood, and thereby facilitating their participation in cognitive processes.
Published Study finds brain connectivity, memory improves in older adults after walking (via sciencedaily.com) Original source
Regular walks strengthen connections in and between brain networks, according to new research, adding to growing evidence linking exercise with slowing the onset of Alzheimer's disease. The study examined the brains and story recollection abilities of older adults with normal brain function and those diagnosed with mild cognitive impairment, which is a slight decline in mental abilities like memory, reasoning and judgment and a risk factor for Alzheimer's.
Published Ready, set, go: New study shows how marathon running affects different foot muscles (via sciencedaily.com) Original source
Marathon running is a popular sport. However, long-distance running can weaken and damage foot muscles, leading to chronic pain and running-related injuries. A new study reveals that marathon running can reduce foot arch height, as well as induce damage to extrinsic foot muscles, which connect the lower leg and foot.
Published Researchers pinpoint brain cells that drive appetite in obesity (via sciencedaily.com) Original source
A group of brain cells discovered by researchers reveals a potential new approach to anti-obesity treatment.
Published Physical activity crucial for poststroke recovery (via sciencedaily.com) Original source
After a stroke, physical activity can be pivotal to successful recovery. People who spend four hours a week exercising after their stroke achieve better functional recovery within six months than those who do not, a new study shows.
Published Behavior patterns of people who achieve clinically significant weight loss (via sciencedaily.com) Original source
A new study analyzing data on over 20,000 U.S. adults links a healthier diet and increased exercise to weight loss that reduces heart disease risk -- while associating skipping meals and taking prescription diet pills with minimal weight loss, weight maintenance or weight gain.
Published Labor induction doesn't always reduce Caesarean birth risk or improve outcomes for term pregnancies (via sciencedaily.com) Original source
Findings conflict with previous national trial results: Women who underwent elective induction were more likely to have a cesarean birth compared with those who underwent expectant management (30% versus 24%.)
Published Impact of maternal stress during pregnancy on child's health (via sciencedaily.com) Original source
New research examines the impact that maternal stress during pregnancy has on the neuro-development of babies.
