New modelling strongly suggests the first smallpox epidemic among Indigenous Australians originated from the British outpost in Sydney and might have killed as many as 220,000 Aboriginal people Fossil reveals the earliest evidence of “right-handedness” in the animal kingdom A recent rat study found that when mothers consumed morphine infused water in adolescence, it had effects on their offspring. Specifically, the offspring were more likely to exhibit anxiety-like behaviors and have specific epigenetic expressions related to poor neuronal plasticity. Study found evidence of partisan behavior in children aged five to nine - they frequently endorsed their own group’s claims even when evidence suggested otherwise. However, if you allow them to respond in private or give them a reason to care about accuracy, the partisanship effect disappears. Spite, a grudge, even fear of hell; the feelings clinicians are trained to treat as danger sometimes hold a suicidal person to life. A new study suggests having a champion for solar power in the house is key to installing the panels. Understanding these family dynamics could help the planet by improving on the 8% adoption rate of residential solar in the U.S., researchers say. Researchers built a robot fish to study how fish may have first evolved to walk on land A diverse toy environment is linked to better infant communication skills. Study found a high number of diverse toys in the home is associated with advanced interaction abilities and early language development in infants.

Some Dark Triad personality traits help the body handle acute stress better, new study finds Painless Swab Detects Oral Cancers in an Hour, With Over 95% Accuracy | The quantitative Malignancy Index Diagnostic System (qMIDS), involves using a brush to swab the suspect lesion, and then analyzing it for signs of mRNA expression from four specific genes linked to oral cancer. Babies’ brains recognize music from as young as three months of age, while spontaneous movements to music emerge by their first birthday and their ability to match movements to it develops later Women who have experienced violence suffer more severe menopausal symptoms and may reach the menopause up to 20 months earlier than those without such a history. The risk of osteoporosis and fractures rises, as well as memory problems and difficulties with attention in cognitive health. LSD could improve motor learning the next day in healthy people High-Dose Vitamin D3 Supplementation During Pregnancy and Test Based Cognitive Performance at Age 10 Years Obesity rates in the U.S. climbed to about 40% of adults and 20% of youth in 2023. More than 20 years of data show a 37% increase in obesity, 23% in abdominal obesity, and over two-fold increase in severe obesity among both adults and youth. Following an anti-inflammatory diet rich in fruits, vegetables, and nuts is linked to a 29% lower risk of dementia, even among people who already have high biological and genetic risk markers for Alzheimer's disease, a 15-year study finds. Early sexual initiation accelerates physical aging, large genetic study finds. Individuals genetically predisposed to early sexual initiation are more likely to experience a shorter lifespan and increased physical frailty. Emerging evidence links tire pollution to Alzheimer’s risk: A chemical called 6PPD-quinone (6PPD-Q), which forms when shaved-off tire particles come into contact with ozone, might interfere with inner workings of the brain cells, leading to Alzheimer's disease.
