Reply to Stroke survivor moves her hand for first time in a decade after groundbreaking treatment by TheTelegraph
From our Science Correspondent Joe Pinkstone ⤵️
A stroke survivor has been able to use cutlery to cut food and feed herself for the first time in a decade, thanks to insertions of electricity into her spine.
Heather Rendulic, who had a stroke in 2012 when she was 22, was left with no mobility in her left hand as a result of chronic post-stroke muscle weakness.
Scientists recruited Ms Rendulic, now 33, and one other stroke survivor, a 47-year-old woman, to be the first people to try out electrical stimulation of the spinal cord with the aim of improving arm and hand motor movements.
The system has been used previously to improve lower leg functionality in people with nerve damage. However, very little research has been done on using it to help people suffering with upper limb impediments.
Scientists created a device that inserts two electrodes into the spinal cord in between vertebrae in the neck area.

From the article: Being overweight is often linked to negatives in children’s physical health but how about to their cognitive health? A study published in PloS One suggests a link between excess weight in preschool children and declined executive functioning.
Overweight and obesity in children has become increasingly prevalent and problematic worldwide in the recent past. Though obesity is thought of commonly as simply being overweight due to poor nutrition and lack of exercise, it is a bit more complex than that. Obesity involves the entire body and can be affected by genetics, environment, and the way these two interact.
Risk factors for childhood obesity can include preterm birth and low birth weight. Cognitive factors, such as executive functioning, have been thought to be related to excess weight by affecting the mental control around healthy habits. A relationship between excess weight and executive functioning impairments has been shown in school-aged children, adolescents, and adults, but there is a gap in literature around preschool aged children, which this study seeks to address.
For their study, Narueporn Likhitweerawong and colleagues utilized 1,181 preschoolers aged 2 to 5 from seven private and public schools in Thailand to serve as their sample. Data was collected in 2021. Schools chosen represented predominantly middle-class socioeconomic status. Children who were underweight or diagnosed with neurodevelopmental or genetic disorders were excluded. Measures included an executive functioning inventory filled out by the participants’ parents, weight status, and pre-specified confounders, such as age, birth weight, breastfeeding status, sex, and more.
Results showed that children who had impaired executive functioning were more likely to be overweight. In particular, impaired inhibition and decreased working memory capacity were both significantly correlated with being overweight for preschoolers in this study.

You are awfully entrenched in your own ideas, there seemed very little wrong to me in what the person you are replying to said.
Mindfulness meditation, has scientifically backed results and that is enough for it to have value in a western context, beyond that meditation is not an inherently Buddhist concept, its just become the standard association.
All the best and happy meditating.

Reply to comment by [deleted] in Climate change and the projected savannization of the Brazilian Amazon threaten most land-based mammals that live there, new research shows. The “savannization” here refers to when lush rainforest gives way to a drier, open landscape that resembles savanna but is actually degraded forest. by MistWeaver80
It's turning around in a generation, and carbon sequesteration will be needed on a large scale, but it's literally doable.

In this figure from that paper, while the flat peak is 120 dB centred around 20 Hz, with an A-weighting this only translates to about peak 95 dBA around 200 to 1000 Hz.
Measurements for occupational safety are done with A weighting, but would there be any safety concern with an unweighted 127 dB SPL at 20 Hz? or is A weighting still sufficient ?
Edit: higher res figure

Reply to According to a new study, researchers propose a novel theory about how the molecules of life may have developed a preferred chirality, or “handedness.” Understanding more about how the concept influences our living beings could help scientists develop drugs to fight molecular disease, like cancer. by Impossible_Cookie596

Since not everyone has access to the paywalled article, here's the preprint version of it.

you joke, but NIST probably has a standard 'rice cereal' somewhere in their catalogue for testing

Not at all. This is a test if our models are correct. If they find a dipole moment, it has to be explained by new theories. If they don't, then they can rule out proposed extensions of our current models that would imply a non-zero dipole moment. There's no comparable model that predicts the n-th digit of pi to be a 7 and if it's a 6 we need a new model.
