More Americans in their golden years are going hungry

More Americans in their golden years are going hungry

In a country as wealthy as the United States, it may come as a surprise that one in 12 seniors do not have access to adequate food due to lack of money or other financial resources. Continue reading

Life stressors trigger neurological disorders, researchers find

Life stressors trigger neurological disorders, researchers find

When mothers are exposed to trauma, illness, alcohol or other drug abuse, these stressors may activate a single molecular trigger in brain cells that can go awry and activate conditions such as schizophrenia, post-traumatic stress disorder and some forms of autism. Until now, it has been unclear how much these stressors have impacted the cells of a developing brain. Past studies have shown that when an expectant mother exposes herself to alcohol or drug abuse or she experiences some trauma or illness, her baby may later develop a psychiatric disorder, including some forms of autism or post-traumatic stress disorder, later in life.

Radiation therapy for cervical cancer increases risk for colorectal cancer

Radiation therapy for cervical cancer increases risk for colorectal cancer

Researchers at the University of Texas Medical Branch at Galveston are the first to recommend that young women treated with radiation for cervical cancer should begin colorectal cancer screening earlier than traditionally recommended. The UTMB researchers, finding a high incidence of secondary colorectal cancers among cervical cancer survivors treated with radiation, offer new recommendations that the younger women in this group begin colorectal cancer screening about eight years after their initial cervical cancer diagnosis instead of waiting until age 50 Continue reading

Eavesdropping on brain cell chatter

Eavesdropping on brain cell chatter

Everything we do — all of our movements, thoughts and feelings — are the result of neurons talking with one another, and recent studies have suggested that some of the conversations might not be all that private. Brain cells known as astrocytes may be listening in on, or even participating in, some of those discussions. But a new mouse study suggests that astrocytes might only be tuning in part of the time — specifically, when the neurons get really excited about something. Continue reading

Scientists re-define what’s healthy in newest analysis for human microbiome project

Scientists re-define what’s healthy in newest analysis for human microbiome project

As scientists catalog the trillions of bacteria found in every nook and cranny of the human body, a new look by the University of Michigan shows wide variation in the types of bacteria found in healthy people. Continue reading

New standards proposed for gauging muscle decline in older adults

New standards proposed for gauging muscle decline in older adults

Sarcopenia — the age-related loss of muscle mass and strength — may put up to 50 percent of seniors at greater risk for disability, yet there is no consensus within the medical community for how this condition should be measured. However, a new collection of articles appearing in The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences (volume 69, number 5) lays out an empirically derived set of criteria for diagnosing sarcopenia. These recommendations are a result of the Foundation for the National Institutes of Health Biomarkers Consortium Sarcopenia Project, which includes scientists and grantees from the National Institutes of Health, along with other partners in government, academia, and the private sector.

Brain changes associated with casual marijuana use in young adults: More ‘joints’ equal more damage

Brain changes associated with casual marijuana use in young adults: More ‘joints’ equal more damage

The size and shape of two brain regions involved in emotion and motivation may differ in young adults who smoke marijuana at least once a week, according to a study published April 16 in The Journal of Neuroscience . The findings suggest that recreational marijuana use may lead to previously unidentified brain changes, and highlight the importance of research aimed at understanding the long-term effects of low to moderate marijuana use on the brain. Marijuana is the most commonly used illicit drug in the United States, with an estimated 18.9 million people reporting recent use, according to the most current analysis of the National Survey on Drug Use and Mental Health.

Changes in processing, handling could reduce commercial fishing injuries

Changes in processing, handling could reduce commercial fishing injuries

Handling frozen fish caused nearly half of all injuries aboard commercial freezer-trawlers and about a quarter of the injuries on freezer-longliner vessels operating off the coast of Alaska, new research from Oregon State University shows. Many of those injuries and others aboard the two types of vessels could be prevented with the right interventions, and the research methods used in the study could help identify and reduce injuries and fatalities in other types of commercial fishing, said researcher Devin Lucas.
