Rock Snot Genomics: The origin of common algae

Diatoms are one of the most common types of phytoplankton and a major group of algae. One species, Didymosphenia geminata, is responsible for creating thick blooms in mountain streams and ponds. It’s a menace to ocean-going vessels, where it causes drag, and in hospitals, where it can coat moist surfaces and promote bacteria.

For researchers in the lab of Edward Theriot at The University of Texas at Austin, diatoms (and their snot) are rich objects of biological research. Read the full

Building a better battery

It’s been a rough ride lately for the lithium-ion battery. Though practically all of us carry one around — they power everything from cell phones to iPods — the lightweight cells have sparked some high-profile product failures.

It was bad enough when they caused laptop computers to burst into flames, leading to millions of recalled batteries since 2000. Their reputation took another hit in January, when battery fires in two of Boeing’s new 787 Dreamliner planes caused airlines to ground their

My space? Your space? What makes it our space?

Take a look at your bedroom. Is it scattered with laundry? Adorned with photos? Are you only leaving a sliver of space in the closet for your partner’s clothes? These seemingly mundane domestic scenarios may reveal a surprising amount of information about a couple’s relationship, according to a forthcoming study led by Lindsay Graham, a psychology graduate student at The University of Texas at Austin.

In collaboration with Sam Gosling, professor of psychology and author of “Snoop: What Your Stuff Says

Engineering immune cells to resist infection from HIV

Researchers at The University of Texas at Austin and the Stanford University School of Medicine have found a novel way to engineer key cells of the immune system so they remain resistant to infection from HIV, the virus that causes AIDS.
The study, which was published this week in Molecular Therapy, describes the use of a kind of molecular scissors to cut and paste a series of HIV-resistant genes into T cells, specialized immune cells targeted by the virus.

The new approach

Folic acid one of several discoveries that made Esmond Snell world-renowned

Biochemist Esmond Snell, a researcher at The University of Texas at Austin and the University of California, Berkeley, left a legacy that continues to affect people’s lives.

Part of his legacy is that fewer babies are born with neural tube defects such as spina bifida and anencephaly because of one of his discoveries.

In 1941 Snell, who died in 2003, and Texas colleague Herschel Mitchell discovered folic acid, a B vitamin needed to make DNA and RNA and that enables red blood

Biologist Aims to Hunt Down and Destroy Viruses Where They Hide

Although his goal is to someday help destroy HIV and other viruses and retroviruses that form persistent, lifelong infections, biologist Chris Sullivan can’t help but admire the strategies that many of these viruses have evolved to evade our defenses.

“It’s brilliant,” says Sullivan, associate professor of molecular genetics and microbiology. “Take Herpes simplex virus 1, for instance, which is one of the masters. It goes in and infects very long-lived neurons, and then

Developers of Manufacturing Technology Named Inventors of the Year at UT Austin

The University of Texas at Austin honored two researchers whose collaboration led to a company that aims to change how electronics are made.

Professors C. Grant Willson and S.V. Sreenivasan received the Inventor of the Year award Thursday (Dec. 6, 2012) for developing a nanolithography process used for manufacturing computer chips, hard drives and other electronic components.

They took their research beyond the laboratory in co-founding Molecular Imprints Inc., an Austin-based company with more than 100 employees.

“I congratulate Professor Sreenivasan and Professor Willson for

Eavesdropping on the Secret Lives of Fish

There’s a problem for scientists trying to understand why populations of southern flounder have been in such decline in the waters of the Texas Gulf.

“They live underwater,” says Benjamin Walther, assistant professor of marine science in the College of Natural Sciences. “We can’t just follow them from birth to death. You can tag a fish with acoustic or satellite tags when it’s an adult, but typically the young are too small and fragile. So you’re missing that whole big piece

Silver Tsunami brings crest of Alzheimer’s Disease

It’s called the “Silver Tsunami” – the swelling number of baby boomers surpassing age 65. As medical advancements extend their lives, they’re expected to live well into their 80s and 90s – outlasting any generation in American history.

But among Americans over 80 – who represent the fastest growing segment of the U.S. population – half are debilitated with a neurodegenerative disorder. Of this group, 5.4 million now have Alzheimer’s Disease. By year 2050, that number is expected to balloon to

The White Widow Model: A New Scenario for the Birth of Type Ia Supernovae

J. Craig Wheeler has studied the exploding stars called supernovae for more than four decades. Now he has a new idea on the identity of the “parents” of one of the most important types of supernovae — the Type Ia, those used as “standard candles” in cosmology studies that led to the discovery of dark energy, the mysterious force causing the universe’s expansion to speed up.

Wheeler lays out
