Harvard’s transforming robotic fabric could lead to therapeutic wearables

Researchers have developed a textile-based soft robot that can regulate itself without being tethered to any machine. They designed a robotic fabric called Smart Thermally Actuating Textiles (STATs) is composed of tightly sealed pouches containing a fluid known as Novec 7000. Electronically-conductive silver-plated threads are weaved into the material which serve as the smart fabricโ€™s heater and sensor elements. When heated, the fluid vaporizes, and its volume expands up to 100-fold to change the fabricโ€™s shape. But when itโ€™s cooled, it condenses back to a liquid, thereby deflating the fabric.

BionicSwift, an ultralight bionic bird from Festo that flies like real birds

BionicSwift is equipped with wings that imitate the plumage of real birds, capable of flying safely like real birds and in a coordinated pattern in a defined airspace. The robotic โ€œfeatheredโ€ bird has a wingspan of 68 cm, a body length of 44.5 cm, and a weight of 42 grams. The wings are made with โ€œlamellaeโ€ (feathers) made from overlapping sheets of ultralight and flexible foam, but at the same time very robust. The artificial birds have a radio marker that sends signals so that its exact position can be tracked by a computer that acts as a navigation system to set up pre-programmed routes and flight paths for the birds while avoiding collisions.

Sniffing out smell

Researchers describe for the first time how relationships between different odors are encoded in the olfactory cortex, the region of brain responsible for processing smell. By delivering odors with selected molecular structures and analyzing neural activity in awake mice, the team showed that neuronal representations of smell in the cortex reflect chemical similarities between odors, thus enabling scents to be placed into categories by the brain. Moreover, these representations can be rewired by sensory experiences. The results open new avenues of study to better understand how the brain transforms information about odor chemistry into the perception of smell.

When It Comes to PTSD, Laughing Gas Is No Laughing Matter

A one-hour dose of 50 percent nitrous oxide (N2O) and 50 percent pure oxygen (delivered via face mask) may help military veterans with post-traumatic stress disorder (PTSD), according to preliminary results from a new pilot study. Within a couple of hours of this 60-minute laughing gas treatment, two of the three veterans Self-reported a reduction of PTSD symptoms lasting up to one week. Assuming that the researchers are able to replicate these initial findings in a larger independent sample, it’s possible that nitrous oxide could get FDA approval for treating PTSD at some point in the distant future.

Supermarkets snub coconut goods picked by monkeys

A number of supermarkets have removed some coconut water and oil from their shelves after it emerged the products were made with fruit picked by monkeys. The monkeys are snatched from the wild and trained to pick up to 1,000 coconuts a day, People for the Ethical Treatment of Animals (Peta) said. In response Waitrose, Ocado, Co-op and Boots vowed to stop selling some goods. Meanwhile, Morrisons said it had already removed products made with monkey-picked coconuts from its shelves. In a statement, Waitrose said: “As part of our animal welfare policy, we have committed to never knowingly sell any products sourced from monkey labour.”

Air France and sister airline to cut 7,580 jobs

Air France confirmed plans to cut some 7,500 jobs including 1,000 at sister airline HOP!, as staff protested over its response to the collapse in travel due to the coronavirus pandemic. The French flag carrier, part of Franco-Dutch group Air France-KLM, said it had lost 15 million euros a day during the worst part of the crisis, which also saw its revenues plunge by 95%. It did not see traffic returning to 2019 levels before 2024. As a result, it plans to cut 6,560 or 16% of jobs at the main airline by the end of 2022. Air France said it would give priority to voluntary departures, early retirement and staff mobility. It did not rule out compulsory redundancies, however.
