Revolutionary ultra-thin meta-lens enables full-color imaging

Light of various colors goes at various speeds in various materials and structures. This is the reason we see white light split into its...
In a milestone for earthquake forecasting, researchers report that their physics-based model of California earthquake hazards replicated estimates from the state’s leading statistical model. In the above radar image, a section of California’s San Andreas fault can be seen below the Crystal Springs Reservoir (in black), with San Francisco (in pink) to the east.

Scientists discovered the source of strange negative gravity

The objects' motion we see in our everyday lives are governed by Newton's Laws of Motion and gravity. But according to scientists at the...
Using machine-learning tools to analyze 46,000 earthquakes at The Geysers geothermal field in California, researchers discovered patterns that correspond to water-injection flows, suggesting a link to the mechanical processes that produce earthquakes. (Photo credit: Stepheng3)

Using Machine learning tools to gain new insights from Earthquake data

Scientists at the Columbia University have discovered a totally new way to study earthquakes. They picked out different types of earthquakes from three years using...

Old brains can make new neurons, study finds

A new research by the Columbia University Vagelos College of Physicians and Surgeons suggests that human brain makes new neurons throughout life. Scientists were able to...
Utpal Pajvani and KyeongJin Kim found that inhibiting gamma secretase in the liver reduces plasma triglyceride levels.

A novel approach to lowering high triglycerides

Triglycerides are fats that cells use as fuel. They are transported to cells by means of the circulatory system, however, when triglyceride levels are...
Co-authors Rebecca Schnall, PhD, and Nancy Reame, PhD, share the distinction of having received an endowed chair established by Mary Dickey Lindsay ’45, an inspirational leader in women’s health advocacy and reproductive rights.

Women with HIV Experience More Fatigue, Muscle Aches After Menopause

Advancements in treatment during recent decades, HIV has largely become a chronic condition. This implies a more prominent level of individuals with HIV are living longer;...
