Evidence that the brain’s ability to control thinking relies on beta rhythms
MIT neuroscientists have found evidence that the brain’s ability to control what it’s thinking about relies on low-frequency brain waves known as beta rhythms.

Quench of LHC inner triplet magnet causes a small leak with major consequences
At 1.00 a.m. + 17 seconds on Monday, 17 July, the LHC beams were dumped after only 9 minutes in collision due to a radiofrequency interlock caused by an electrical perturbation. Approximately 300 milliseconds after the beams were cleanly dumped, several superconducting magnets around the LHC quenched – i.e. they lost…

Ozone hole goes large again
Measurements from the Copernicus Sentinel-5P satellite show that this year’s ozone hole over Antarctica is one of the biggest on record. The hole, which is what scientists call an ‘ozone depleting area,’ reached a size of 26 million sq km on 16 September 2023. This is roughly three times the size of Brazil.

Critical step found in DNA repair, cellular aging (2017)
The body’s ability to repair DNA damage declines with age, which causes gradual cell demise, overall bodily degeneration, and greater susceptibility to cancer. Experiments in mice suggest a way to thwart DNA damage.

Study urges caution when comparing neural networks to the brain
Neuroscientists often use neural networks to model the kind of tasks the brain performs, in hopes that the models could suggest new hypotheses regarding how the brain itself performs those tasks. But a group of MIT researchers urges that more caution should be taken when interpreting these models.

Suppressing a gene by using its antibody can lead to tooth growth: animal study
Tooth loss is a widespread problem in adults and results in poor quality of life. Currently, solutions to this problem include artificial teeth and implants. But these aren’t as good as “real teeth,” and they don’t markedly improve quality of life. Now, scientists from Japan have made a discovery that can make…
