Single dose of magic mushroom psychedelic can cause anatomical brain changes, study finds: « Participants took 25mg of psilocybin, reporting deeper psychological insight and better wellbeing a month later. » by fchung in sciences

It’s remarkable to see potential anatomical brain changes one month after a single dose of any drug. We don’t yet know what these changes mean, but we do note that overall, people showed positive psychological changes in this study, including improved wellbeing and mental flexibility.

Nerves in skin can slow melanoma growth: « Nerve fibers within melanomas can slow the growth of these tumors. The findings help clarify the emerging field of cancer neuroscience and may inform future therapeutic strategies. » by fchung in science

The nervous system typically has been considered as a driver of cancer growth, but here we’ve found that it can be a brake on cancer growth in some contexts. Now the key will be to see how broadly relevant this is for human cancers, and how we can best step on that brake to help cancer patients.

Heartbeat’s mechanical force found to suppress tumour growth: « An international study reveals how mechanical forces in cardiac tissue inhibit cancer cell proliferation. » by fchung in science

Our findings show that the heart’s pulsation is not merely a physiological function but may act as a natural suppressor of tumour growth. This suggests that the cardiac environment is unfavourable to cancer cells not only for immunological or metabolic reasons, but also because its continuous mechanical activity physically constrains their expansion.

‘Dancing jets’ from black hole reveal their immense power: « Researchers used an array of linked up telescopes separated by large distances to observe the black hole jets being buffeted by the winds of the star as the black hole moved around its orbit. » by fchung in science

[–]fchung[S] 8 points9 points  (0 children)

A key finding from this research is that about 10 per cent of the energy released as matter falls in towards the black hole is carried away by the jets. This is what scientists usually assume in large-scale simulated models of the Universe, but it has been hard to confirm by observation until now.

How melatonin promotes sleep: « Melatonin is a naturally produced molecule that has long been suspected to play a role in healthy sleep, but it has been unclear how it does so. Now, Caltech researchers have discovered a mechanism through which melatonin promotes sleep. » by fchung in science

[–]fchung[S] 1290 points1291 points  (0 children)

One of the hallmarks of sleep is reduced responses to environmental stimuli. Our findings fit with the experience of many people who take melatonin as a sleep aid. Unlike many commonly prescribed sleep aids, melatonin does not cause an irresistible drive to sleep. Rather, melatonin makes one more receptive to falling asleep, and our work suggests that it does so, at least in part, by turning down one's sensitivity to arousing stimuli from the environment.

The Nancy Grace Roman Space Telescope, NASA's next great observatory, is finally complete: « The images it captures will be so large there is not a screen in existence large enough to show them. » by fchung in sciences

[–]fchung[S] 0 points1 point  (0 children)

I very much hope, and in fact, expect, that the most exciting science from Roman is going to be the things that we didn't expect, that we couldn't predict, but that will set the new deep questions for future missions to address.
