Observational studies of the relationship between alcohol use and telomere length have produced conflicting results. The largest such study to date, of 4,567 individuals, found no association between alcohol intake and either baseline or longitudinal change in telomere length [9]. Another analysis of two American cohorts (n = 2623) also reported null findings [10]. On the other hand, a few small studies (sample size range: 255‑1800) have observed associations with heavy drinking or AUD. Participants with AUD have been reported to have shorter telomeres compared to healthy controls [11]. A longitudinal study of Helsinki businessmen observed that higher midlife alcohol consumption was associated with shorter telomere length in older age [8]. Drinking 30 g/day of alcohol in older participants was associated with shorter telomeres in a Korean study [12]. Associations were stronger in those experiencing the alcohol flush reaction, raising the intriguing possibility that acetaldehyde, ethanol’s toxic breakdown product, is mechanistically involved. In a recent review of 27 studies, 10 showed significant associations between alcohol use and telomere length [13]. The studies included cross-sectional and longitudinal designs. The majority comprised European participants with ages ranging from the third to seventh decade. Most studies observed positive associations between alcohol and LTL. However heterogeneity between studies in methods of quantifying telomere length and categorizing alcohol intake hindered meta-analysis and aggregation of the data.

MR seeks to identify potentially causal determinants of an outcome. It estimates the association between genetically predicted levels of an exposure and an outcome of interest. Residual confounding and reverse causation aim to be less of a concern than in most other methods of analyzing observational data [14]. With MR, genetic proxies can be used to study the effects of genetically-predicted variability in alcohol consumption or AUD risk. To our knowledge, no MR study of alcohol and telomere length has yet been attempted.

We conducted a large observational study of two alcohol phenotypes, alcohol consumption and AUD, and leucocyte. We then performed linear MR analyses to investigate the evidence for a causal effect between alcohol consumption/AUD and LTL. Estimates generated by our observational and genetic methods were compared. Genetic distinction between different alcohol use traits motivates their separate analysis. Quantity/frequency measures such as drinks per week and AUDIT-C (Alcohol Use Disorders Identification Test Consumption, a 3 item screening tool), while moderately genetically correlated with AUD, have distinct patterns of genetic correlation with other traits [13]. Furthermore, as there has been much speculation about potential J-shaped relationships between alcohol and health outcomes [15], we performed a non-linear MR analysis to examine the shape of the relationship between alcohol consumption and telomere length.

A chess-playing robot fractured the finger of its 7-year-old opponent during a tournament in Moscow last week.

The incident happened after the boy hurried the artificial intelligence-powered robot, the president of the Moscow Chess Federation told the Russian state news agency Tass. “The robot broke the child’s finger — this, of course, is bad,” Sergey Lazarev said.

Video of the incident, which occurred at the Moscow Chess Open competition Tuesday, went viral on social media after a post by the local outlet Baza News.

The European Space Agency released new images of one of the deepest regions on the planet from its Mars Express orbiter.

ESA’s Mars Express orbiter imaged the stunning depths of Mars’ Valles Marineris, a gaping crevasse that is miles deeper than Earth’s Grand Canyon.

The Expedition 67 crewmembers aboard the International Space Station spent Tuesday predominantly on research, maintenance, and cargo transfer operations.

Research beneficial to humans on Earth and future crews in space is happening around the clock aboard the orbiting laboratory. NASA Flight Engineer Kjell Lindgren used a majority of his day to service samples for the Immunosenescence investigation inside the Life Science Glovebox. Results from this study may one day inform treatments for accelerated aging processes commonly observed in microgravity and contribute to countermeasures for normal aging progression.

Figuring out what’s going on in the brain is generally considered to be somewhere between extremely difficult and impossible. One major challenge is that the best ways to do so are room-sized machines relegated to hospitals — but brain.space is hoping that its portable, powerful and, most importantly, user-friendly EEG helmet could power new applications and treatments at home and, as a sort of cork pop for its debut, in space.

Electroencephalography, or EEG, is an established method for monitoring certain signals the brain produces. An EEG can indicate which areas of the cortex are active, whether the user is concentrating, agitated, and so on. It’s not nearly as precise as an MRI, but all you need for an EEG is a set of electrical contacts on the scalp, while an MRI machine is huge, loud and incredibly expensive.

There’s been precious little advancement in EEG tech, though, and it’s often done more or less the same way it was done decades ago. Recently, that’s begun to change with devices like Cognixion’s, which uses re-engineered EEG to interpret specific signals with the goal of allowing people with motor impairments to communicate.

Technology enabling better care conditions for patients and wireless EEG monitoring can help patients with neurological conditions.

Death comes to all of us, and it’s never easy. If cemeteries and funeral homes don’t give you warm fuzzies, then consider instead having your body covered in soil and bacteria so it can be composted into mulch.

The idea of a human remains becoming rich soil that can lead to new life seems — oddly refreshing.

After a decade of planning and fundraising and a successful bid to change Washington state law, Recompose, a composting funeral home, is finally open for business.
