Does genetics determine your reaction to psychedelics? A recent study suggests that they could

Research on psychedelics like LSD and psilocybin as treatments for substance use disorders, depression, anxiety, and PTSD holds incredible promise. The evidence is so compelling that some states are decriminalizing possession of these drugs and legalizing their therapeutic use, even though they remain under the federal government’s Schedule 1 classification. New drugs for mental health …

Study finds 'likely biological and genetic overlap' between carpal tunnel syndrome and migraine

Child’s body weight has limited effects on mood and behavioral problems, study finds

According to a study published today in eLife [20 December]. The findings suggest that some previous studies, which have shown a strong link between childhood obesity and mental health, may not have fully considered family genetics and environmental factors. Obese children are more likely to be diagnosed with depression, anxiety, or attention deficit hyperactivity disorder …

New study sheds light on evolutionary quirks of remote islands

Scientists have discovered at least two genetic pathways leading to the same physical outcome for a species of Solomon Islands flycatcher. Research indicates that there is more than one way to build a blackbird. Nature often finds a way when it comes to the biological necessities of survival and reproduction. Sometimes there is more than …

More than one in 10 species could be extinct by the end of the century, study warns

Earth could lose more than a tenth of its plant and animal species by the end of the century on current trends, according to new research that comes as nearly 3,000 scientists call on governments to act to stop the destruction of nature in the final days of negotiations. at COP15. The climate crisis will …

NEJM Study: Genetic Anomaly Hidden Behind Late-Onset Common Cerebellar Ataxia

Researchers from the University of Miami Miller School of Medicine, McGill University and other institutions have found that a well-hidden genetic variation in the FGF14 gene, called DNA tandem repeat expansion, causes a common form of late-onset cerebellar ataxia, a disorder that interferes with coordinated movement. Tandem repeat expansions are only found in 50 conditions, …

Study investigates 'virgin birth' in aquarium sharks, even when potential mates are nearby

Study investigates ‘virgin birth’ in aquarium sharks, even when potential mates are nearby

An adult zebra shark at the Shedd Aquarium’s Wild Reef exhibit. Credit: Shedd Aquarium / Brenna Hernandez Asexual reproduction is common in animals like starfish, deep-sea worms, and stick insects, but in vertebrates it is a rarity. A process called parthenogenesis allows some females to fertilize an egg with their own genetic material, producing offspring …
