How do you benchmark something that goes back 10 or 80 million years, like simulations of ancient genes and proteins, when you don't have a time machine to travel back and check the results? There's a way. And it shows the simulations are…
Will Ratcliff tried something many scientists doubted would ever succeed. He pushed yeast to evolve in the lab from single-cell to multicellular beings. “It was a kind of Hail Mary pass,” he said. It worked, and opened up a path to sustained…
Nine graduate students launch Georgia Tech’s third interdisciplinary life sciences Ph.D.
The University System of Georgia Board of Regents has appointed Georgia Tech faculty members Seymour E. Goodman, NIcholas V. Hud, and Vladimir Tsukruk as Regents’ Professors and Alexa Harter as a Regents’ Researcher. The titles represent the…
Global warming is expanding ocean regions where oxygen has already vanished. There, newly discovered bacteria deplete waters of nitrogen, a nutrient essential to life. Though nitrogen depletion itself is natural, it appears to be expanding along…
Suddenly, a roundworm overhauls an array of survival strategies, and researchers suspect multiple mutations caused them. But they're surprised when they trace the sweeping changes back to one tiny mutation on a single gene. It's a great hint at a…
When early terrestrial animals began moving about on mud and sand 360 million years ago, the powerful tails they used as fish may have been more important than scientists previously realized. That’s one conclusion from a new study of African…
A new study from the Georgia Institute of Technology finds that older people struggle to remember important details because their brains can’t resist the irrelevant “stuff” they soak up subconsciously.
A new modeling study conducted by researchers in Georgia Tech’s School of Earth and Atmospheric Sciences shows that for decades, air pollution drifting from East Asia out over the world’s largest ocean has kicked off a chain reaction that…
A nanoparticle commonly used in food, cosmetics, sunscreen and other products can have subtle effects on the activity of genes expressing enzymes that address oxidative stress inside two types of cells. While the titanium dioxide (TiO2)…
Over the past several decades, scientists have observed a significant increase in the melting of glacial land ice on the island of Greenland, spurring concerns about global sea level rise and the long-term effects of atmospheric warming. What has…
On April 20, 2010, an explosion on the Deepwater Horizon (DWH) oil rig released a torrent of oil in the seafloor of the Gulf of Mexico, discharging close to 5 million barrels of oil in 87 days. It was the largest accidental oil spill in U.S.…
In humans, cholera is among the world’s most deadly diseases, killing as many as 140,000 persons a year, according to World Health Organization statistics. But in aquatic environments far away from humans, the same bacterium attacks neighboring…
Georgia Techresearchers are participating in a multicenter genetic study of prostate cancer in Sub-Saharan Africa to try to find new information about the genetic causes of prostate cancer. Men of African descent suffer disproportionately from…
The Torres lab has been awarded a four year, $1.2 million grant by the National Institutes of General Medical Sciences to investigate a newly discovered regulatory mechanism that controls G protein signaling, a process essential for the…
Marine microorganisms play a critical role in capturing atmospheric carbon, but a new study finds much less certainty than previously believed about the populations of the viruses that infect these important organisms.
