Cancer-Causing Virus Blocks Human Immune Response, Study Shows

Cancer-Causing Virus Blocks Human Immune Response, Study Shows

AUSTIN, Texas — Scientists at The University of Texas at Austin and the University of California at San Francisco have revealed how a type of cancer-causing virus called Epstein-Barr virus (EBV) outwits the human body's immune response. By helping explain why some cancer therapies fail, the discovery might lead to more effective treatments. EBV, a virus…   » Continue Reading

Computer Scientists at UT Austin Crack Code for Redrawing Bird Family Tree

AUSTIN, Texas — A new computational technique developed at The University of Texas at Austin has enabled an international consortium to produce an avian tree of life that points to the origins of various bird species.

Florida Lizards Evolve Rapidly, Within 15 Years and 20 Generations

Florida Lizards Evolve Rapidly, Within 15 Years and 20 Generations

AUSTIN, Texas — Scientists working on islands in Florida have documented the rapid evolution of a native lizard species — in as little as 15 years — as a result of pressure from an invading lizard species, introduced from Cuba.

Walking on All Fours Is Not Backward Evolution, Study Shows

Contradicting earlier claims, “The Family That Walks on All Fours,” a group of quadrupedal humans made famous by a 2006 BBC documentary, have simply adapted to their inability to walk upright and do not represent an example of backward evolution, according to new research by Liza Shapiro, an anthropologist at The University of Texas at…   » Continue Reading

New Research Revises Conventions for Deciphering Color in Dinosaurs While Suggesting Connection between Color and Physiology

New research that revises recently established conventions allowing scientists to decipher color in dinosaurs may also provide a tool for understanding the evolutionary emergence of flight and changes in dinosaur physiology prior to the origin of flight.

Bats Use Water Ripples to Hunt Frogs

Bats Use Water Ripples to Hunt Frogs

AUSTIN, Texas — As the male túngara frog serenades female frogs from a pond, he creates watery ripples that make him easier to target by rivals and predators such as bats, according to researchers from The University of Texas at Austin, the Smithsonian Tropical Research Institute (STRI), Leiden University and Salisbury University.

Seahorse Heads Have a ‘No Wake Zone’ That’s Made for Catching Prey

Seahorses are slow, docile creatures, but their heads are perfectly shaped to sneak up and quickly snatch prey, according to marine scientists from The University of Texas at Austin.

Singing Mice Protect Their Turf With High-Pitched Tunes

Singing Mice Protect Their Turf With High-Pitched Tunes

Two species of tawny brown singing mice that live deep in the mountain cloud forests of Costa Rica and Panama set their boundaries by emitting high-pitched trills, researchers at The University of Texas at Austin have discovered. Although males of both the Alston's singing mouse (Scotinomys teguina) and Chiriqui singing mouse (S. xerampelinus sing to…   » Continue Reading
