The discovery of 92-million-year-old fossil ants in New Jersey amber confirms the existence of ants during the Age of Dinosaurs. The fossils show a metapleural gland, essential for ants' social system and ecological dominance.
Researchers at Columbia University have identified the first human gene associated with hair loss, offering new possibilities for treating various forms of alopecia. The 'hairless' gene initiates a cascade of events that stimulate hair growth, potentially leading to more effective treatments and gene therapy.
A national survey found that most women aged 35 and older experience leg swelling, tired legs, or restless feelings weekly. Many report being forced to take time off work or quit jobs due to leg health concerns, affecting their career progress and social activities.
Researchers have shown that TMS can modify brain reorganization, potentially accelerating recovery and rehabilitation. The technique may also be used to promote learning and improve brain function after injuries or trauma.
Researchers have developed a gene therapy technique that makes recipient's immune system tolerant of newly engrafted organs, eliminating the need for lifelong immunosuppressive drug therapy. The approach involves introducing a vector carrying the CTLA4Ig protein into an organ preservation solution before transplant surgery.
Physicists at Columbia University will receive funding to develop sensitive electronics for the Large Hadron Collider, enabling detection of new particles created during high-energy collisions. The electronics will handle a massive rate of collisions while maintaining precision of 0.25 percent.
A study by University of Washington professors Virginia Berninger and Robert Abbott found that handwriting instruction, combined with composition practice, significantly improved writing accuracy and quality in first-graders. The research also showed a direct carry-over from handwriting to compositional skills throughout the elementary...
Research by Dr. Dan A. Oren may help alleviate SAD symptoms such as fatigue, sadness, weight gain, and sleep problems. His study suggests that blood absorbs light energy from the sun, regulating biological clocks and behavior.
