How lack of touch has impacted us during the pandemic

Physical touch is one of the five basic senses, and itâs a part of our everyday lives.
âBeing social and meeting other people is, I think, the essence of being human, Dr. Helena Wasling said. If thatâs taken away, it would be strange if we were not affected by it.â
Neuroscience researcher Helena Wasling has spent years researching the human touch system. She says touch impacts how people feel and act. So when the pandemic takes away our ability to physically interact with each other, thereâs a part of us that feels empty.

Kimberly Potter, the 26-year police veteran who fatally shot Daunte Wright during a traffic stop in Minnesota on April 11, has been charged with second-degree manslaughter. Prosecutors will be tasked to prove to the courts that she was negligent in drawing and firing her Glock pistol instead of her Taser stun gun when subduing the 20-year old.
A widely scrutinized body-cam video shows Potter yelling “Taser! Taser! Taser!
“ before firing a bullet into Wright’s chest which killed him on the scene. Beneath what appears to be another appalling accidental shooting actually belies a complex, systemic issue at the core of America’s problematic, hyper-aggressive policing philosophy. This ethos is ultimately reflected in the design of standard tools law enforcement officers carry and how they use them. It’s bigger than an industrial design problem, but it’s certainly part of the issue.

Indian jumping ants, or Harpegnathos saltator, are unique in more ways than one

A decreased brain size is thought to allow the ants to divert their energy to egg production, as brain tissue is metabolically expensive to maintain, the study says

Indian jumping ants can shrink their brains by 20 per cent and then expand them back again to allow energy to be temporarily diverted towards egg production, according to a new study.
The inch-long arthropods were already known to be able to catch and kill prey twice their size, jump four inches in the air and compete in 40-day royal rumble death matches to decide the next queen of the colony.
Non-invasive neuromodulation approaches can prevent invasive surgery in Parkinson s patients
From optogenetics to sonogenetics to magnetognetics, scientists around the world are investigating new techniques to treat Parkinson s disease without the need for invasive surgery.
There is still no treatment that can reverse the effects of Parkinson s disease, a condition estimated to affect 10 million people worldwide. As life expectancy increases, the number of people suffering from this disease is set to rise in the future, making the need for effective treatment a priority.
Doctors prescribe oral medication to alleviate the main symptoms and, for a few patients, use deep brain stimulation. The electrodes stimulate the affected areas and relieve the reactions induced by the disease such as tremor or rigidity.
