A study reveals that females with Tourette syndrome (TS) are diagnosed later than males and often experience lower tic severity but higher rates of co-occurring OCD. The findings highlight sex-based disparities in TS diagnosis.

Washington University researchers found that sickle cell disease causes brains to appear 14 years older than their actual age, even without stroke. Economic deprivation also accelerates brain aging by seven years in healthy individuals.

Researchers developed a wireless photothermal nanosystem using gold nanoshells to stimulate thermosensitive TRPV1 receptors and clear α-synuclein aggregates in Parkinson’s disease (PD) mice.

Researchers found that body parts like hands defy the size-weight illusion that applies to objects. In a study, participants perceived larger hands as heavier and smaller hands as lighter, contrary to how objects are perceived.

Researchers from Mass General Brigham and Washington University have found that Xenon gas inhalation reduces neuroinflammation, brain atrophy and amyloid and tau pathologies in Alzheimer’s mouse models.

A new study examined the link between children’s characteristics and differences in how their parents treat them, while considering potential moderators such as child age, parent gender and measurement methods.

Waking up does not activate an increase in the release of the stress hormone cortisol, but cortisol does increase in the hours prior to waking.

A landmark study analyzing data from over five million individuals across 29 countries uncovered 700 genetic variants linked to depression, with 100 identified exclusively due to diverse ethnic inclusion.

A study reveals a surprising link between upper body strength and mating success across genders. Using data from 4,316 U.S. adults, researchers found that individuals with greater grip strength reported more lifetime sexual partners.

Rice University researchers analyzed data from 6,620 bird species, uncovering why certain mating systems persist. Lekking, where males display for females without forming bonds, is stable and often evolves directly from monogamy.
