Children with ADHD frequently use healthcare service before diagnosis, study finds

A recent study by University of Nottingham researchers found that children with attention deficit hyperactivity disorder (ADHD) use healthcare services twice as often in the two years before their diagnosis. Children with ADHD are also more likely to see their GP, receive prescriptions, attend hospital for overnight admissions, and hav...

Climate-smart cows could deliver 10-20x more milk in Global South

A team of animal scientists has developed a new breed of cow that can produce up to 20 times the milk of indigenous breeds, offering a potential game changer for subsistence farmers in Tanzania. The breeding process combines the heat and disease resistance of Gyrs with the milk-producing prowess of Holsteins and Jerseys.

Smells like learning

A team of scientists discovered two types of neurons in fruit flies and mice that enable them to identify distinct smells. With experience, these animals can learn to differentiate between very similar odors, a process that could improve machine-learning models and AI systems.

The first oncogene was found more than 40 years ago. CNIO researchers have just discovered that it has a previously unknown mechanism of action

CNIO researchers have discovered a previously unknown mechanism of action for the first oncogene, c-Src. The study reveals that c-Src can autonomously activate itself through autophosphorylation, leading to cancer formation. This finding has significant implications for the development of new drugs targeting this enzyme.

DGIST achieves both efficiency and stability in next-gen solar cells with quantum dot surface stabilization strategy!

A research team at DGIST has developed a new approach to protect the surface of quantum dots using non-polar solvents and covalent ligands, significantly reducing defects and improving efficiency and long-term stability in perovskite quantum dot solar cells. This breakthrough enhances the commercialization of applicable materials.

Trauma-informed training workshops prompt meaningful individual and organizational changes, according to outcomes surveys

A McLean Hospital study found that nearly 600 individuals trained in trauma-informed care reported significant gains in knowledge and improvements to organizational policies. However, the study's findings suggest that lasting changes may require more time and involve larger-scale organizational transformations.

The genetic heritage of the Denisovans may have left its mark on our mental health

A recent study reveals that the Denisovan genetic variant affects zinc regulation and may have provided an evolutionary advantage for our ancestors' adaptation to the cold. This variation has been associated with a greater predisposition to mental health disorders, including depression, schizophrenia, and anxiety-related conditions.

Drawing a tube of blood could assess ALS risk from environmental toxin exposure

Researchers developed an environmental risk score to assess ALS risk and survival using a blood sample, associating several individual pollutants with disease risk. A mixture of pesticides in the blood significantly increased ALS risk, with those in the highest group having twice the risk as those in the lowest.
