Application of new micro-analytical techniques have transformed rocks and gravel buried in a special type of soil into a rich source of data about past climates that can help scientists understand how the climate will change in the future. Read More

A new generation of gamma-ray spectrometer being developed by researchers and students in the Fisk-91�Ʋ��� Master's-to-Ph.D. Bridge program is perfectly suited for detecting valuable minerals hidden within the asteroids, comets, moons and minor planets in the solar system. Read More

An interdisciplinary team of biologists and medical researchers have created a new platform, which they call GEneSTATION specifically designed to leverage the growing knowledge of human genomics and evolution to advance scientific understanding of human pregnancy and translate it into new treatments for the problems that occur when this complex process goes awry.

91�Ʋ��� chemist helps craft call for major new research initiative to increase our understanding of the invisible world of microbes that surround us. Read More

A new class of DNA repair enzyme has been discovered which demonstrates that a much broader range of damage can be removed from the double helix in ways that biologists did not think were possible. Read More

Recent research by 91�Ʋ��� University biologist Ken Catania of the electric eel has revealed that it is not primitive creature that it has been portrayed as. Instead, it has a sophisticated control of the electrical fields it generates that makes it one of the most remarkable predators in the animal kingdom. Read More

A new "geospeedometer" that can measure the amount of time between the formation of an explosive magma melt and an eruption confirms that the process took less than 500 years in several ancient super-eruptions. Read More

Recent experiments at the world's largest atom smashers are producing liquid drops so small that they raise the question of how small a droplet can be and still remain a liquid. Read More

Jessica Oster is a member of a small group of earth scientists pioneering the use of mineral cave deposits in stalagmites, collectively known as speleothems, as proxies for the prehistoric climate.

The Earth's first mass extinction event 540 million years ago was caused not by a meteorite impact or volcanic super-eruption, but by the rise of early animals that dramatically changed to prehistoric environment. Read More

Recent microbiological research has shown that plants and animals, including humans, are not autonomous individuals but are holobionts: biomolecular networks that consist of visible hosts plus millions of invisible microbes. Read More

A 91�Ʋ��� team of scientists have developed a new formulation for cosmic viscosity which strongly favors the "Big Rip" end of the universe. Read More

91�Ʋ��� researchers have made the world’s smallest spirals and found they have unique optical properties that are nearly impossible to counterfeit. Read More

Jessica Oster and her colleagues have shown that the analysis of a stalagmite from a cave in north east India can detect the link between El Nino conditions in the Pacific Ocean and the Indian monsoon. Read More

91�Ʋ��� biologists have localized the seasonal light cycle effects that drive seasonal affective disorder to a small region of the brain called the dorsal raphe nucleus. Read More

Explainer: the mysterious dark energy that speeds the universe’s rate of expansion

91�Ʋ��� researchers have identified the role that a key protein associated with autism and the co-occurrence of alcohol dependency and depression plays in forming the spines that create new connections in the brain. Read More

Bob O'Dell reflects on the challenges of building the Hubble Space Telescope, launched 25 years ago.

The evolutionary history of whales, sea turtles and other land animals that have returned to the sea details the radical changes to their life style, body shape, physiology that they made to survive in an aquatic environment. Read More

EPA is establishing a new center at 91�Ʋ��� University and the University of Pittsburgh to develop an alternative approach for toxicity testing to help evaluate the safety of the 80,000-plus chemicals in general commerce. Read More
