UA professor uses NSF grant to develop 3-D-printed biodegradable polymer scaffolds

Laboratory-engineered noses, jaws and ears. The stuff science fiction is made of is coming soon from a University of Akron lab. With a $390,000 NSF grant, Matthew Becker, UA professor of polymer science and biomedical engineering, is developing 3-D-printed biodegradable polymer scaffolds, the frameworks within which bone will grow, with the hope of changing the face of craniofacial reconstruction.

White sexual-minority men have higher positive racial attitudes, empathy than white heterosexual men

White sexual-minority men may be more empathic toward other minority groups compared to their heterosexual white peers. A new study from the University of Houston College of Education compared the attitudes of white heterosexual men to those of white sexual-minority men.

Women's sexuality may be more flexible, adaptive than men's, study reveals

Romantic opportunities appear to influence women's sexual identities -- but not men's, suggests a new study that will be presented at the 110th Annual Meeting of the American Sociological Association.

New research finds five different types of prostate cancer

New research has revealed that five different types of prostate cancer exist. How will this discovery change the outlook of prostate cancer screening? World renowned robotic prostate cancer surgeon, Dr. David Samadi, evaluates.

Study sheds light on fertility concerns of young breast cancer patients

Concerns about fertility kept a third of young women with breast cancer from taking tamoxifen, despite its known benefit in reducing the risk of breast cancer coming back.

High dietary iron intake suppresses hormone that regulates appetite

Here's one more reason to cut down on the amount of red meat you eat. Using an animal model, researchers at Wake Forest Baptist Medical Center have found that dietary iron intake, equivalent to heavy red meat consumption, suppresses leptin, a hormone that regulates appetite.

Mayo Clinic scientists discover potential way to reprogram cancer cells back to normalcy

Cancer researchers dream of the day they can force tumor cells to morph back to the normal cells they once were. Now, researchers on Mayo Clinic's Florida campus have discovered a way to potentially reprogram cancer cells back to normalcy.

Researchers find that humans carry more antibiotic-resistant staphylococci than farm animals

Antibiotic-resistant bacteria are a concern for the health and well-being of both humans and farm animals. One of the most common and costly diseases faced by the dairy industry is bovine mastitis, a potentially fatal bacterial inflammation of the mammary gland (IMI). Widespread use of antibiotics to treat the disease is often blamed for generating antibiotic-resistant bacteria.

Electronic triggers can help identify, reduce follow-up delays in evaluation for cancer diagnosis

Electronic triggers designed to search for key data, developed by researchers at Baylor College of Medicine and Michael E. DeBakey Veterans Affairs Medical Center, were able to identify and reduce follow-up delays for patients being evaluated for a diagnosis of colon or prostate cancer.

FSU investigator solves cell division mystery

In the second part of his lab's recent one-two punch, Florida State University researcher Daniel Kaplan said he has solved a cell division mystery in a way that will intrigue the makers of cancer-fighting drugs.

Some head impact sensors too slow and miss most serious, angular hits

With increasing concern about concussions from sports, some players have started wearing electronic sensors to measure head impacts.

Researchers reveal new electrical mechanism that can control molecular switches regulating cancer cell growth

The molecular switches regulating human cell growth do a great job of replacing cells that die during the course of a lifetime. But when they misfire, life-threatening cancers can occur. Research led by scientists at The University of Texas Health Science Center at Houston (UTHealth) has revealed a new electrical mechanism that can control these switches.

Study: Influenza vaccines offer sustained protection up to 6 months during flu season

Individuals who received the flu vaccine were protected for up to 6 months post-vaccination, the duration of most flu seasons, according to a study presented at the 2015 International Conference on Emerging Infectious Diseases.

Physical activity improves cognitive flexibility in older adults

One day soon, doctors may determine how physically active you are simply by imaging your brain. Physically fit people tend to have larger brain volumes and more intact white matter than their less-fit peers. Now a new study reveals that older adults who regularly engage in moderate to vigorous physical activity have more variable brain activity at rest than those who don't. This variability is associated with better cognitive performance, researchers say.

Karolinska Institutet study may lead to development of better immune-based cancer therapies

A study by researchers at Sweden's Karolinska Institutet is the first to suggest that cells in the tumour blood vessels contribute to a local environment that protects the cancer cells from tumour-killing immune cells. The results, which are being published in the 'Journal of the National Cancer Institute', can contribute to the development of better immune-based cancer therapies.

New study affirms value of influenza vaccination among older people

A new study of the records of millions of nursing home residents affirms the value of influenza vaccination among the elderly. The Brown University analysis found that between 2000 and 2009, the better matched the vaccine was for the influenza strain going around, the fewer nursing home residents died or were hospitalized.

Louisiana Tech team discovers new nanocomposite that could be used in targeted drug delivery for fighting cancer

Faculty at Louisiana Tech University have discovered, for the first time, a new nanocomposite formed by the self-assembly of copper and a biological component that occurs under physiological conditions, which are similar those found in the human body and could be used in targeted drug delivery for fighting diseases such as cancer.

Researchers awarded $6.4 million grant to identify causes of neurodevelopmental disorders in children with CHDs

As advances in medicine are giving rise to growing numbers of children who are surviving severe heart defects, a phenomenon is emerging that is catching parents and healthcare providers off-guard. Over half of these children also have a seemingly unrelated disability: neurodevelopmental disorders. Some have severe cognitive and motor deficits that arise early.

Brief exposure to sudden sounds or mild trauma can form long-term memories

Researchers at NYU Langone Medical Center have found how even brief exposure to sudden sounds or mild trauma can form permanent, long-term brain connections, or memories, in a specific region of the brain. Moreover, the research team, working with rats, says it was able to chemically stimulate those biological pathways in the locus coeruleus -- the area of the brain best known for releasing the "fight or flight" hormone noradrenaline -- to heighten and improve the animals' hearing.
