Britain on Sunday announced additional measures to stop the spread of the Omicron coronavirus variant, including the extension of booster jabs to people over 30.

From Tuesday, fully vaccinated contacts of people who test positive for Covid-19 will be required to take daily lateral flow tests for seven days.

But those who have not had one or two shots of a Covid vaccine will have to self-isolate for 10 days, the Department of Health and Social Care said.

Senescent cells refer to those that have stopped dividing but do not die. They damage nearby healthy cells by releasing chemicals that cause inflammation.

The team identified a protein found in senescent cells in humans and mice and created a peptide vaccine based on an amino acid that constitutes the protein.

The vaccine enables the body to create antibodies that attach themselves to senescent cells, which are removed by white blood cells that adhere to the antibodies.

The earliest genetic traces of Native American ancestry among Polynesians.

The peopling of Polynesia was a stunning achievement: Beginning around 800 C.E., audacious Polynesian navigators in double-hulled sailing canoes used the stars and their knowledge of the waves to discover specks of land separated by thousands of kilometers of open ocean. Within just a few centuries, they had populated most of the Pacific Ocean’s far-flung islands. Now, researchers have used modern DNA samples to trace the exploration in detail, working out what order the islands were settled in and dating each new landfall to within a few decades.

“The whole question of the settlement of Polynesia has been going on for 200 years,” says University of Hawaii, Manoa, archaeologist Patrick Kirch, who was not involved in the research. “This is a really great paper, and I’m happy to see it.”

Chinese scientists have developed a targeted delivery system that can bring gene-editing tools to colon cells, offering a precise cure for inflammatory bowel disease.

The study, published on Thursday in the journal Science Advances, reported a CRISPR-Cas9 prodrug nanosystem that can transport a gene-editing protein exclusively to inflammatory lesions in mice colons and then “switch on” the protein.

What if Elon Musk told you that you could store your memories as a backup and then download them into a robot body. Sounds like science fiction to you, Well believe it or not it’s true and he has already launched a company called Neuralink to pursue this futuristic goal.

But how does it work and how exactly is elon musk going to pull this one-off. Well, we’ll answer these questions and take a deeper look into Neuralink and how it could change humanity forever.

The all-in-one POGO Automatic glucose meter from Intuity Medical is finally available to people with diabetes in the United States.

A maze is a popular device among psychologists to assess the learning capacity of mice or rats. But how about robots? Can they learn to successfully navigate the twists and turns of a labyrinth? Now, researchers at the Eindhoven University of Technology (TU/e) in the Netherlands and the Max Planck Institute for Polymer Research in Mainz, Germany, have proven they can. Their robot bases its decisions on the very system humans use to think and act: the brain. The study, which was published in Science Advances, paves the way to exciting new applications of neuromorphic devices in health and beyond.

Machine learning and neural networks have become all the rage in recent years, and quite understandably so, considering their many successes in image recognition, medical diagnosis, e-commerce and many other fields. Still though, this software-based approach to machine intelligence has its drawbacks, not least because it consumes so.

The system could help physicians select the least risky treatments in urgent situations, such as treating sepsis.

Sepsis claims the lives of nearly 270,000 people in the U.S. each year. The unpredictable medical condition can progress rapidly, leading to a swift drop in blood pressure, tissue damage, multiple organ failure, and death.

Prompt interventions by medical professionals save lives, but some sepsis treatments can also contribute to a patient’s deterioration, so choosing the optimal therapy can be a difficult task. For instance, in the early hours of severe sepsis, administering too much fluid intravenously can increase a patient’s risk of death.

I would prefer it if the data was anonymized and handed back to the patient via an AI interface on the assessment, — Recommended actions and risks involved with each decision. It would then be up to the patient to share the data with a doctor or not, to decide how much data they want to share, and to what extent recommendations can interfere with their day to day life. I’m gonna have a glass of wine. AI: this is your 3rd glass today, do you want to know the risks associated with this decision? No. AI: ok-do you want to monitor vital health statistics in relation to drinking wine instead of water? No. AI; Do you want / Just shut up. Erase all records of my wine drinking and do not monitor this going forward. To live means to die, at least for now. Don’t touch my wine 🍷

Remote technology could save lives by monitoring health from home or outside the hospital. It could also push patients and health care providers further apart.
