New evidence shows carbon's importance to ocean life's survival 252 million years ago
A new study led by UT Arlington Earth & Environmental Scientists shows for the first time how carbon offered a mode of survival for some ocean life after one of the greatest mass extinctions in the history of Earth.

Study reveals molecular genetic mechanisms driving breast cancer progression
Researchers at UT Southwestern Medical Center have uncovered how the body's inflammatory response can alter how estrogen promotes the growth of breast cancer cells.

Targeting dangerous inflammation inside artery plaque
A research team showed that a nanotherapeutic medicine can halt the growth of artery plaque cells resulting in the fast reduction of the inflammation that may cause a heart attack.

A complex landscape has both vulnerabilities and resilience to climate change
In Central Appalachia, changes in precipitation and temperatures are likely to reduce habitat suitability for some tree species, including iconic species such as American beech, eastern hemlock, eastern white pine, red spruce, and sugar maple.

Case Western Reserve to lead international research on resistance to bacteria causing TB
After discovering a unique group of people resistant to tuberculosis (TB) infection, Case Western Reserve researchers are leading an international team dedicated to understanding exactly how they fight off a disease that claims 1.5 million lives each year.

Studies find $1 test using gold nanoparticles outperforms PSA screen for prostate cancer
A test that uses gold nanoparticles to detect early-stage prostate cancer costs less than $1, returns results in minutes and is more accurate than standard PSA screening, pilot studies show.

CRISPR-Cas editing of C. albicans holds promise for overcoming deadly fungal infections
Candida albicans is a human pathogen that causes potentially lethal infections in immunocompromised individuals.

Possible progress against Parkinson's and good news for stem cell therapies
Researchers at D'Or Institute for Research and Education and Federal University of Rio de Janeiro have taken an important step toward using the implantation of stem cell-generated neurons as a treatment for Parkinson's disease.

Fertility patients' history is best predictor of risk for major depression
Fertility treatment patients and their partners are at significant risk for developing Major Depressive Disorder, and a key factor in predicting their risk is whether they have a previous diagnosis of major depression, according to new research from San Francisco State University.

New genetic clues emerge on origin of Hirschsprung's disease
Genetic studies in humans, zebrafish and mice have revealed how two different types of genetic variations team up to cause a rare condition called Hirschsprung's disease.

Better actionless than action-taking
A recent study has found that unconscious priming for acceptance works better than deliberate acceptance in coping with frustrating emotions, with little involvement from cognitive efforts and better maintenance of emotional stability.

Scientists take a deep dive for undersea warriors
Office of Naval Research officials announced today new research support to develop a prototype diving helmet that could revolutionize diving missions -- and provide greater safety for divers.

Doctor at Rhode Island Hospital develops Ebola virus diagnostic tool
Adam C. Levine, M.D., an emergency medicine physician at Rhode Island Hospital and The Miriam Hospital who treated Ebola-infected patients in Liberia last year, used his field experience to create a tool to determine the likelihood that patients presenting with Ebola symptoms will actually carry the virus.

Latest advances in nuclear cardiology and cardiac CT
The latest advances in nuclear cardiology and cardiac CT imaging are set to be announced at the International Conference on Nuclear Cardiology and Cardiac CT (ICNC) 12.

Northwest Alaska bird, mammal species could experience habitat change from warming climate
Of the 201 bird and mammal species that call northwest Alaska's arctic and subarctic region their home, 195 of them -- or, roughly, 97 percent -- could experience some form of habitat loss or gain stemming from climate change, a new US Forest Service-led study has found.

Camera chip provides superfine 3-D resolution
Imagine you need to have an almost exact copy of an object.

Rice can borrow stronger immunity from other plant species, study shows
Rice, one of the world's main staple foods, can boost its built-in immunity against invading disease-causing microbes when immune receptor genes are transferred via genetic engineering from a totally different plant group, this new study shows.

Science and medicine have a 'publication pollution' problem
The scientific community is facing a 'pollution problem' in academic publishing, one that poses a serious threat to the 'trustworthiness, utility, and value of science and medicine,' according to one of the country's leading medical ethicists.

UCLA research links HIV to age-accelerating cellular changes
People undergoing treatment for HIV-1 have an increased risk for earlier onset of age-related illnesses such as some cancers, renal and kidney disease, frailty, osteoporosis and neurocognitive disease.

NASA sees Typhoon Maysak weakening
Various NASA satellites and instruments continue to see the weakening trend in Typhoon Maysak as it moved through the Philippine Sea on April 2 and 3 toward a landfall in Luzon on April 4.

Three UTSW faculty elected as new members of the American Society for Clinical Investigation
Dr. Jay Horton, professor of internal medicine and of molecular genetics at UT Southwestern Medical Center, has been elected a Councilor of the American Society for Clinical Investigation.

MD Anderson, Astellas Pharma sign option agreement for monoclonal antibody drug targeting acute myeloid leukemia
The University of Texas MD Anderson Cancer Center and Astellas Pharma Inc. have signed an option agreement to research and develop a new treatment for patients with acute myeloid leukemia.

Gender difference in moral judgments rooted in emotion, not reasoning, study finds
Men, relative to women, show a stronger preference for utilitarian over deontological judgments, according to a new meta-analysis of 40 studies.

NASA catches a tropical cyclone's birth in 3-D
Tropical Cyclone 05W was born in the Northwestern Pacific Ocean on April 3 west of the island of Pohnpei when the GPM satellite passed over it and analyzed its rainfall rates.

OU physicists first to create new molecule with record-setting dipole moment
A proposed pathway to construct quantum computers may be the outcome of research by a University of Oklahoma physics team that has created a new molecule based on the interaction between a highly-excited type of atom known as a Rydberg atom and a ground-state atom.

Frustrated magnets -- new experiment reveals clues to their discontent
An experiment conducted by Princeton researchers has revealed an unlikely behavior in a class of materials called frustrated magnets, addressing a long-debated question about the nature of these discontented quantum materials.
