Researchers identify genetic differences affecting toddler activity levels and discover they are also associated with ADHD

A study published in Nature Human Behaviour has identified genetic differences affecting toddler activity levels, which also overlap with Attention Deficit Hyperactivity Disorder (ADHD). The research found that 10% of the variation in toddler activity levels can be explained by common genetic differences discovered by the researchers.

A simple message helps keep stem cell donors on track

Researchers from the University of Osaka found that adding a sentence about limited donor compatibility increased donors' willingness to progress through pre-donation testing. This simple message resulted in a 7.3% increase in donor completion rates, offsetting nearly half of projected donor declines.

The Lancet: Blood pressure and cholesterol levels in adults over 40 with obesity increasingly similar to adults with normal BMI, study suggests

A study published in The Lancet found that blood pressure and cholesterol levels among adults with obesity have converged with those with a normal Body Mass Index (BMI) over the past three decades, particularly in high-income countries. This trend is attributed to the greater use of cholesterol-lowering medication and blood pressure me...

Novel plasmid pCM3 harboring the aminoglycoside phosphotransferase gene aph(3) confers phosphorylation-driven streptomycin resistance in the Gram-positive plant pathogen Clavibacter michiganensis

The novel plasmid pCM3 harbors the aph(3) gene, which encodes an aminoglycoside 3'-phosphotransferase conferring resistance to streptomycin in Clavibacter michiganensis. The study reveals a phosphorylation-driven resistance mechanism, with APH(3) phosphorylating streptomycin to ablate its inhibitory activity.

The cost of violence

A new study estimates the global cost of violence to be between $23 and $34 trillion per year. Domestic violence is found to be a major contributor to this cost, with intangible costs such as pain, suffering, and traumatization being significantly higher than the overall cost of collective violence like war and terrorism.

Success story brown bear: 3D analysis reveals the secret of their climate resilience

Could “Trojan horse”-type microorganisms that exploit symbiotic systems be candidates for new biological pesticides?

Researchers have identified a pathogenic microorganism that invades the gut of stink bugs by masquerading as a symbiotic microorganism, leading to nearly 100% mortality. This discovery could lead to the development of new biological pesticides with high species-specificity and lower environmental impact.

Psychedelics and ADHD

Researchers from Wroclaw Medical University analyzed the available literature on psychedelics and ADHD. While some studies reported short-term improvements, these findings cannot determine treatment efficacy due to study design limitations. The current evidence is insufficient to support psychedelics as a treatment for ADHD.
