Researchers from the New York University School of Medicine have developed a brain implant designed to detect pain sensations in real-time and deliver bursts of pain-relieving stimulation. The device is still deeply experimental but a new proof of concept study demonstrates it working effectively in rodent models.
In the world of brain implants the chasm between science fiction and reality is still quite vast. Apart from some exciting human tests showing paralyzed individuals with implants regaining a sense of touch or controlling computers with their mind, most research in the field is still nascent.
Animal tests have demonstrated incremental technological advances, such as pigs broadcasting neural activity or monkeys playing Pong. Now, an interface that can detect pain signals in one part of the brain and immediately respond with stimulation to another part of the brain targeted to relieve that pain has been developed.
Biologists in the UK and Austria have discovered 71 new imprinted genes in the mouse genome.
Biologists at the Universities of Bath and Vienna have discovered 71 new ‘imprinted’ genes in the mouse genome, a finding that takes them a step closer to unraveling some of the mysteries of epigenetics – an area of science that describes how genes are switched on (and off) in different cells at different stages in development and adulthood.
To understand the importance of imprinted genes to inheritance, we need to step back and ask how inheritance works in general. Most of the thirty trillion cells in a person’s body contain genes that come from both their mother and father, with each parent contributing one version of each gene. The unique combination of genes goes part of the way to making an individual unique. Usually, each gene in a pair is equally active or inactive in a given cell. This is not the case for imprinted genes. These genes – which make up less than one percent of the total of 20000+ genes – tend to be more active (sometimes much more active) in one parental version than the other.
China is seeing a high-tech greenhouse boom as food supply disruptions sparked by coronavirus lockdowns accelerated the development of modern farming techniques.
SHANGHAI, June 4 (Reuters) — At Chongming Island just outside Shanghai, China’s most populous city, workers collect and pack tomatoes and cucumbers at a glass greenhouse operated by Dutch company FoodVentures, which harvested their first batch of produce at the site in May.
The facility is one of dozens sprouting up on the outskirts of China’s megacities that utilise high-end technology to manage irrigation, temperature and lighting systems to grow vegetables within easy reach of a large and affluent consumer base.

Shingles vaccination is the only way to protect against shingles and postherpetic neuralgia (PHN), the most common complication from shingles. CDC recommends that healthy adults 50 years and older get two doses of the shingles vaccine called Shingrix (recombinant zoster vaccine), separated by 2 to 6 months, to prevent shingles and the complications from the disease. Your doctor or pharmacist can give you Shingrix as a shot in your upper arm.
Shingrix provides strong protection against shingles and PHN. Two doses of Shingrix is more than 90% effective at preventing shingles and PHN. Protection stays above 85% for at least the first four years after you get vaccinated.
