Cyborg technology is bringing us real-life electronic skin, prosthetics and ultra-flexible circuits. Now taking this human-machine concept to an unprecedented level, pioneering scientists are working on the seamless marriage between electronics and brain signaling with the potential to transform our understanding of how the brain works — and how to treat its most devastating diseases.
Trauma before enlistment linked to high suicide rates among military personnel, veterans, research finds
High rates of suicide among military service members and veterans may be related to traumatic experiences they had before enlisting, making them more vulnerable to suicidal behavior when coping with combat and multiple deployments, according to the findings of several recent studies. Experiencing child abuse, being sexually victimized by someone not in the service and exhibiting suicidal behavior before enlisting are significant risk factors for service members and veterans who attempt or commit suicide.
Frequent marijuana use can have a significant negative effect on the brains of teenagers and young adults, including cognitive decline, poor attention and memory, and decreased IQ, according to psychologists. "It needs to be emphasized that regular cannabis use, which we consider once a week, is not safe and may result in addiction and neurocognitive damage, especially in youth," said one expert.
The pursuit of true happiness can lead people to lifestyles that will not only be satisfying but will be better for the environment, according to an overview of psychological research. Several studies have determined that people’s basic psychological needs include competence, autonomy, positive relationships, self-acceptance and personal growth. And research has shown that rather than fulfilling these needs, the pursuit of money and possessions takes time away from more personally fulfilling activities and social relationships.
Many of the nation's hospitals in the U.S. struggled to meet a federally mandated electronic health records deadline, and as a result could collectively face millions of dollars in reduced Medicare payments this year, a study shows.
Piles of ancient shells provide the first reliable long-term record for the powerful driver of year-to-year climate changes. Results show that the El Niños 10,000 years ago were as strong and frequent as they are today. The study results question how well computer models can reproduce historical El Niño cycles, or predict how they could change under future climates.
A new nerve repair technique yields better results and fewer side effects than other existing techniques, research shows. Traumatic nerve injuries are common, and when nerves are severed, they do not heal on their own and must be repaired surgically. Injuries that are not clean-cut -- such as saw injuries, farm equipment injuries, and gunshot wounds -- may result in a gap in the nerve.
Using the genome editing tool known as CRISPR, researchers were able to selectively silence two genes in human papilloma virus that are responsible for the growth and survival of cervical carcinoma cells. After silencing the two HPV genes, the cancer cell's normal self-destruct machinery went into action.
People learn better and recall more when given the impression that they will soon have to teach newly acquired material to someone else, suggests new research. Findings of the study suggest that simply telling learners that they would later teach another student changes their mindset enough so that they engage in more effective approaches to learning than did their peers who simply expected a test.
In individuals with multiple sclerosis, patterns of brain activity associated with learning were maintained at six months post training, scientists report in a new article following up on a long term study. For the pilot study, participants underwent evaluation of memory performance and brain activity at baseline, immediately following memory retraining, and at 6-month followup. Results showed that the patterns of increased cerebral activation that correlated with learning were maintained at 6-month followup.
An increased risk of emergency operative delivery is linked with increasing maternal age, suggests a new study. The study used a sample of 169,583 low risk, first-time mothers in Norway, to examine the association between maternal age and emergency operative delivery, which include emergency caesarean section and operative vaginal delivery (forceps or ventouse).
When we think of ill effects from lead exposure various neurologic problems usually come to mind. Now researchers say another health impact can be added to the list: obesity. Even at low levels, lead is associated with obesity in mice whose mothers were exposed to the chemical, researchers found. Specifically male mice exposed to lead had an 8-10 percent increase in weight.
A long-unanswered question about how two of the world’s most common substances interact has been answered by researchers. In a new paper, chemical and biological engineers report fundamental discoveries about how water reacts with metal oxides.
Office workers with more natural light exposure at the office had longer sleep duration, better sleep quality, more physical activity and better quality of life compared to office workers with less light exposure in the workplace, a study shows. "There is increasing evidence that exposure to light, during the day, particularly in the morning, is beneficial to your health via its effects on mood, alertness and metabolism," said the senior study author.
A computer algorithm enables users to instantly change the weather, time of day, season, or other features in outdoor photos with simple text commands. Machine learning and a clever database make it possible.
Frailty is a common condition associated with old age, characterized by weight loss, weakness, decreased activity level and reduced mobility, which together increase the risk of injury and death. Yet, not all elderly people become frail; some remain vigorous and robust well into old-age. The question remains: why?
A decade after first identifying serum amyloid P (SAP) as a key protein in human blood that controls routine tissue-related processes from scarring to healing, two scientists continue to make encouraging progress in the fight against fibrotic disease.
Uric acid may play a role in causing metabolic syndrome, a cluster of risk factors that increases the risk of heart disease and type 2 diabetes, a new study indicates. Uric acid is a normal waste product removed from the body by the kidneys and intestines and released in urine and stool. Elevated levels of uric acid are known to cause gout, an accumulation of the acid in the joints. High levels also are associated with the markers of metabolic syndrome.
New clues to early detection and personalized treatment of ovarian cancer have been made by researchers. Ovarian cancer is currently one of the most difficult cancers to diagnose early due to the lack of symptoms that are unique to the illness. Successful treatment is difficult at this late stage, resulting in high mortality rates.
Planetary scientists have shed some light on the bombardment history of our solar system by studying a unique volcanic meteorite recovered in Western Australia. Captured on camera seven years ago falling on the WA side of the Nullarbor Plain, the Bunburra Rockhole Meterorite has unique characteristics that suggest it came from a large asteroid that has never before been identified.
