- Neuroscientists achieve the unthinkable - talking to someone who’s asleep, and they’ve already done it with several people.
- Cross-national research team demonstrated two-way communication with lucid dreamers in the REM (rapid eye movement) sleep phase.
- Eye movements generate current, which is recorded by electrodes placed around the eyes, and the signals are translated to dialogue.
- Studying the mind during sleep used to be limited to people telling stories about their dreams after waking up, so this is a big gamechanger.
- Psychology experiments with sleeping people are now possible, and it could greatly enhance our understanding of consciousness and the mind’s abilities.
- Injecting stem cells into veins of patients with spinal cord injuries led to a big improvement in their motor functions.
- Half the patients in the study regained some key functions - walking, using hands - just weeks after the injection.
- The stem cells were taken from the patients themselves.
- To make this clinical trial possible, Yale and Sapporo university teams had to do years of preclinical laboratory work.
- These results are promising and give hope, yet study authors say it will still take years before doctors will be able to fix brain and spinal cord injuries this way.
- Whether you perform best in the morning or evening depends on your chronotype - ‘larks’ work early, ‘night owls’ work late.
- Because night owls go to sleep later but have to get up early with everyone else, they incur sleep debt and need catch-up sleep on non-work days, which is bad for health.
- To explore this, researchers used data from a 1966 Finland birth cohort study, initially consisting of 12,058 children.
- At age 46, 2672 men and 3159 women from the study were questioned about their chronotypes in 2012, and monitored for 4 years afterwards.
- Compared to larks, owls had worse ratings for variables related to sleep and health, and were twice more likely to underperform at work.
- Scientists identified stem cells that can regenerate hair growth.
- They’re planning to launch clinical trials to apply those cells to treat male-pattern baldness.
- World’s largest study (data from almost half a million people) of genes involved in stomach ulcers shows that ulcers are linked to depression.
- Study author says he got the idea when he noticed that stomach issues often got reduced after people underwent psychotherapy or psychiatry.
- The study explains why stomach ulcers and depression often go hand-in-hand in patients.
- Overall, the study could help scientists provide gene-based risk scores to patients in order to prevent stomach ulcers.
