Astronauts lend insight into the feasibility of humans becoming a space-faring species. They are getting closer to sending humans on extended trips into space. SpaceX is planning on sending the first humans to Mars in 2024 and they will likely soon set our sights for destinations further than that. They recently had the opportunity to interview two of the U.S. astronauts who have spent the most time in space and ask them about the feasibility of humans becoming a space-faring species.

A study determines that the first myth is that buprenorphine is more dangerous than other interventions physicians master during training. Expanding the availability of medication treatment for opioid use disorder in primary care settings would be a major step toward reducing overdose deaths, write two physicians specializing in addiction medicine and healthcare delivery. The study was published in New England Journal of Medicine. In their Perspectives article entitled "Primary Care and the Opioid-Overdose Crisis Buprenorphine Myths and Realities."
Using MRI brain scans, researchers found that elderly people who feel younger than their age show fewer signs of brain aging, compared with those who feel their age or older than their age. While everyone gets older, not everyone feels their age. A recent study finds that such feelings, called subjective age, may reflect brain aging.
The study was published in open-access journal Frontiers in Aging Neuroscience. This study is the first to find a link between subjective age and brain aging. The results suggest that elderly people who feel older than their age should consider caring for their brain health.
A sophisticated atomic-level computer simulation has allowed researchers of SISSA and the National Research center (CNR-IOM—Institute for Materials Manufacturing) to shed light on the function of the spliceosome, a molecular machine within the splicing speckles of the cell nucleus. The spliceosome is composed of five filaments of RNA and hundreds of proteins. The study was published in the Proceedings of the National Academy of Sciences (PNAS).
According to a study, researchers describe trends in the use of end of life care strategies by people with advanced COPD in Ontario, Canada. For patients with advanced chronic obstructive pulmonary disease (COPD), the use of formal palliative care services and long-term oxygen therapy has increased but remains low. The study was published online in the American Journal of Respiratory and Critical Care Medicine.
A new study showed that scores the variables associated with mortality rates for patients who develop intra-abdominal sepsis after surgery may help guide care and improve outcomes. A study in the American Journal of Critical Care (AJCC) finds that a scoring system based on the concept of Predisposition, Infection/injury type, Response, and Organ dysfunction (PIRO) was useful in predicting mortality in surgical intensive care patients with severe sepsis or septic shock due to an intra-abdominal source.
A retrospective study the aim of the authors was to examine the effect of gentamicin on the individual semicircular canals after the low dose, single injection intratympanic gentamicin therapy in Meniere’s disease. The antibiotic gentamicin has been used to successfully treat a rare illness that affects the inner ear.
Evaluation of the results of treatment administered to 32 patients. However, the analysis found that initial measurements do not provide a basis for predicting the method's long-term effectiveness. The antibiotic's effect on the vestibular system was also investigated, revealing strong correlations between the impacts on the individual semicircular canals.
Research team shows that testosterone, the male sex hormone, increases men's preference for status goods compared to goods of similar perceived quality but seen as lower in status. The paper, "Single-Dose Testosterone Administration Increases Men's Preference for Status Goods," was published in Nature Communications.
Squamous cell carcinoma (SCC) is the second most common form of skin cancer, and its incidence is increasing. When surgical management is not an option, finding a safe and efficacious treatment is a challenge. Mounting evidence suggests that the human papillomavirus (HPV) is involved in the pathogenesis of some SCCs. The study was published online in JAMA Dermatology.
According to a new study, researchers examine that pelvic exam does not improve a physician's ability to diagnose certain sexually transmitted diseases (STDs) in adolescent female patients. That is chief among several reasons why the exam's "routine performance should be reconsidered. The study was published in the Annals of Emergency Medicine.
Researchers have found that it is the collection of certain proteins in the brain that triggers our desire to turn in. This new understanding could offer a new target for drugs to treat insomnia and other sleep disorders. They have discovered what happens in the brain when we get sleepy.
They all need sleep to survive, but mystery still surrounds much of our nightly shut-eye. It is not clear what it does to the body or why we need it.
1. Proteins in the brain track synaptic activity, acting like a countdown clock
2. Chemical tags gather on these proteins throughout the day and fall off at night
3. Researchers at the University of Texas say that these maintain wake-sleep balance
4. Targeting these proteins could someday offer a treatment for sleep disorders
In a recent study, the researchers showed that more than 2,000 migrant children have been separated from their families at the United States/Mexico border. Questions about the policy, including how it affects the children's well-being, has led to a suspension of the practice.
For these children, family separation is an additional trauma to an already adverse experience in their home environments and a long, difficult journey to the United States. Even after families are reunited, the uncertainty surrounding these parents' lives could exacerbate feelings of anguish, despair, guilt, blame, and depression negative emotions that disrupt how they learn life skills.
