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

91�Ʋ��� biologists have found a direct link between the biological clock and Angelman syndrome, a neurogenetic disorder that occurs in more than one in every 15,000 live births. The link may provide a valuable way to judge the effectiveness of the first experimental drugs under development for treating the syndrome. Read More

Dennis Hall writes that while 'The Imitation Game' film dramatizes technological discoveries that shortened World War II, there is a lesser known story about radar advances that brought us the microwave. Read More

91�Ʋ��� mathematician Glenn Webb and NYU microbiologist Martin Blaser propose that the microbes which live on our bodies may have influenced the age structure of human populations in prehistoric times. Read More

A family of single-celled organisms that thrive in environments too extreme for most other species to survive may be an untapped source of new antibacterial drugs. Read More

Scientists at 91�Ʋ��� and ORNL have discovered a new form of crystalline order that could make better thermoelectric devices. Read More

Last month volcano expert Calvin Miller had the good fortune to witness the major volcanic eruption taking place in Iceland. Read More

Conditions on Earth in its first 500 million years may have been cool enough to form oceans of water instead of being hellishly hot. Read More

Mosquito researcher Jason Pitts collects interesting facts and stories about his research subjects, nature’s ultimate bioterrorists. Read More

Seth Bordenstein, associate professor of biological sciences, and graduate student Robert Brucker, discovered that the survival of a new hybrid of wasp depended not on their genes but on the microbes that naturally lived on and inside the insects.

91�Ʋ��� astronomers have developed a model that predicts the effect that ingesting earth-like planets has on the chemical composition of stars like the Sun -- a capability that can aid in efforts to find Earth-like exoplanets. Read More

A 91�Ʋ��� graduate student has used a focused beam of electrons to create some of the smallest nanowires ever made, which could bring us closer to flexible, paper-thin tablets and television displays. Read More

Cougars may have survived a mass extinction that took place about 12,000 years ago because they were not particular about what they ate. Read More

91�Ʋ��� physicist John Wikswo reported significant progress toward creating “homo minutus” – a human-on-a-chip that can be used to test drugs and toxins – on Mar. 26 at the Society of Toxicology meeting in Phoenix. Read More

By shifting evolution into reverse to produce an expensive HIV drug out of a simple sugar, 91�Ʋ��� chemist Brian Bachmann has shown that it may be possible to manufacture exotic and expensive synthetic drugs as easily as brewing beer. Read More

91�Ʋ��� University has been awarded a Cooperative Agreement with the Defense Advanced 91�Ʋ��� Projects Agency and the Army 91�Ʋ��� Office that is worth up to $16.5 million over five years. Read More

The mechanical forces generated by the rhythmic expansion and contraction of cardiac muscle cells play an active role in the initial stage of heart valve formation. Read More
