Angelina Jolie received widespread media attention in 2013 when she told the public that she’d tested positive for BRCA1, a gene associated with an increased risk of breast cancer, and subsequently had a double mastectomy. Now research shows this publicity did influence some women’s intentions to seek similar testing.
North Carolina State University researchers have developed an effective and environmentally benign method to combat bacteria by engineering nanoscale particles that add the antimicrobial potency of silver to a core of lignin, a ubiquitous substance found in all plant cells. The findings introduce ideas for better, greener and safer nanotechnology and could lead to enhanced efficiency of antimicrobial products used in agriculture and personal care.

Biomedical engineering researchers have developed a drug delivery system consisting of nanoscale “cocoons” made of DNA that target cancer cells and trick the cells into absorbing the cocoon before unleashing anticancer drugs.
A new study sheds light on how some collegiate student-athletes deal with uncertainties ranging from excelling in both school and sports to their career prospects outside of athletics, and urges university athletic programs to adopt new efforts to support student-athletes.
New research finds that young people who have had mentors are more likely to find work early in their careers that gives them more responsibility and autonomy – ultimately putting them on a path to more financially and personally rewarding careers.
Researchers from NC State University have developed a technique to control populations of the Australian sheep blowfly – a major livestock pest in Australia and New Zealand – by making female flies dependent upon a common antibiotic to survive.
Findings on the genetic blueprint of the relatively primitive dampwood termite highlight key differences and similarities with other social insects like ants, wasps and bees, and provide insight into how social insects evolved.
Increasingly harsh drought conditions may take a serious toll on corn and soybean yields over the next half-century, according to research published in the journal Science. Corn yields could drop by 15 to 30 percent, according to the paper's estimates.
A new study finds that children pay close attention to issues related to money, and that parents should make an effort to talk with their children to ensure that kids don’t develop misconceptions about finance.
In a new study, researchers from North Carolina State University, UNC-Chapel Hill and other institutions have taken the first steps toward creating a roadmap that may help scientists narrow down the genetic cause of numerous diseases.
Building antibiotic compounds at the molecular level requires precision and specialized tools. NC State research may turn an enzyme that acts as a specialized “wrench” in antibiotic assembly into a set of wrenches that will allow for greater customization.
New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor.
To speed up reproduction, there’s no substitute for the tender touch of a live roach. That’s the takeaway from a study examining whether artificial antennae can mimic a cockroach antenna’s capacity to hasten reproduction in cockroach females.

By thoroughly mapping a single specialized tissue involved in wood formation, scientists at North Carolina State University have developed the equivalent of turn-by-turn directions for future plant research.
Paleontologists studying fossilized feathers propose that the shapes of certain microscopic structures inside the feathers can tell us the color of ancient birds. But new research shows that it is not yet possible to tell if these structures are what they seem.
A “one-size-fits-all” model to predict the effects of climate change on savanna vegetation isn’t as effective as examining individual savannas by continent, according to research published in Science this week.
Researchers have developed a technique for creating nanoparticles that carry two different cancer-killing drugs into the body and deliver those drugs to separate parts of the cancer cell where they will be most effective.
Sometimes the cure can be worse than the disease. Pharmaceutical drugs are known for their potential side effects, and now researchers have updated an extensive toxicology database so that it can be used to track information about therapeutic drugs and their unintentional toxic effects.
Research shows that working a job that doesn’t keep 9 a.m. to 5 p.m. hours can hurt the relationships between parents and adolescents, increasing the likelihood that children will engage in delinquent behaviors. However, the researchers found that in some circumstances, an unconventional work schedule can be a benefit for children.
Iron may play a role in preserving ancient tissues within dinosaur fossils, but also may hide them from detection. This finding could open the door to the recovery of more ancient tissues from within fossils.
Research shows companies that screen the social media accounts of job applicants alienate potential employees – making it harder for them to attract top job candidates. In some cases, social media screening even increases the likelihood that job candidates may take legal action against the offending company.
A new species of carnivorous dinosaur – one of the three largest ever discovered in North America – lived alongside and competed with small-bodied tyrannosaurs 98 million years ago. Siats meekerorum, (pronounced see-atch) was the apex predator of its time.

Oysters begin their lives as tiny drifters, but when they mature they settle on reefs. New research from North Carolina State University shows that the sounds of the reef may attract the young oysters, helping them locate their permanent home.
Losing weight is beneficial for human health, but when one partner in a romantic relationship loses weight, it doesn’t always have a positive effect on the relationship. According to new research, there can be a “dark side” to weight loss if both partners are not on board with enacting healthy changes.
