Oct 28th 2024, 13:20

In dementia diseases such as Alzheimer's, incorrectly folded proteins accumulate in the brain. Researchers have now resolved a particularly active species of protein fibrils with unprecedented precision. The formation of potentially toxic molecules on the surface of protein fibrils was studied from early to late stages spanning over a period of hours.

Oct 28th 2024, 13:20

The human genetic code is fully mapped out, providing scientists with a blueprint of the DNA to identify genomic regions and their variations responsible for diseases. Traditional statistical tools effectively pinpoint these genetic 'needles in the haystack,' yet they face challenges in understanding how many genes contribute to diseases, as seen in diabetes or schizophrenia.

Oct 28th 2024, 13:19

A type of therapy that involves applying a magnetic field to both sides of the brain has been shown to be effective at rapidly treating depression in patients for whom standard treatments have been ineffective. The treatment -- known as repetitive transcranial magnetic stimulation (TMS) -- involves placing an electromagnetic coil against the scalp to relay a high-frequency magnetic field to the brain.

Oct 28th 2024, 13:16

Using a national survey of 88,183 adolescents in grades nine to 12, findings show marijuana use declined from 23.1% in 2011 to 15.8% in 2021, with first-time use before age 13 dropping from 8.1% to 4.9%. In 2021, use was highest among 12th graders (22.4%) and 11th graders (18.7%). Notably, in 2021, girls (17.8%) surpassed boys (13.6%) in reported use, reversing previous trends. While Asian, Hispanic, and white adolescents saw significant declines, Black adolescents reported a higher usage rate of 20.5% in 2021, revealing ongoing racial disparities in marijuana use.

Oct 28th 2024, 13:16

New research shows that stimulation of the lumbosacral vertebrae region significantly elevated low blood pressure, unlike cervical or upper thoracic stimulation.

Oct 28th 2024, 13:15

As cannabis is legalized and is more accessible in various forms across the country, there is increasing concern among health care providers about potential impact on children. Researchers have new findings to add to the existing evidence that cannabis exposure before birth can negatively impact children.
