The U.S. is recommending a "pause" in administration of the single-dose Johnson & Johnson COVID-19 vaccine to investigate reports of potentially dangerous blood clots. In a joint statement Tuesday, the Centers for Disease Control and Prevention and the Food and Drug Administration said they were investigating clots in six women that occurred 6 to [...]
The South African coronavirus variant is better at "breaking through" the defences of the Pfizer/BioNTech vaccine than other forms of the virus, Israeli experts said Sunday. However, one of the authors told AFP that while the study showed the variant to be relatively successful in infecting vaccinated people, it did not provide any data [...]
EPFL scientists have developed AI-powered nanosensors that let researchers track various kinds of biological molecules without disturbing them. The tiny world of biomolecules is rich in fascinating interactions between a plethora of different agents such as intricate nanomachines (proteins), shape-shifting vessels (lipid complexes), chains of vital information (DNA) and energy fuel (carbohydrates). Yet the [...]
A team of researchers from the Institute for Infectious Diseases (IFIK) at the University of Bern and the Federal Institute of Virology and Immunology (IVI) have assessed virus growth and activation of the cellular defense mechanisms in the respiratory tract. They have shown that natural temperature differences that exist in the upper and lower [...]
Researchers at Brown University have succeeded in creating the first wireless, implantable, rechargeable, long-term brain-computer interface. The wireless BCIs have been implanted in pigs and monkeys for over 13 months without issue, and human subjects are next. We’ve covered BCIs extensively here on ExtremeTech, but historically they’ve been bulky and tethered to a computer. [...]
The coronavirus outbreak made household names of companies like Moderna Inc. and BioNTech SE, whose shots offered hope for ending the pandemic. Now a new wave of vaccines is on the horizon that may get the world over the finish line of inoculation. Protecting 7.7 billion people is a herculean task. There are more than 250 [...]
Researchers at the University of Southampton have developed a new way of using nanomaterials to identify and enrich skeletal stem cells—a discovery which could eventually lead to new treatments for major bone fractures and the repair of lost or damaged bone. Working together, a team of physicists, chemists and tissue engineering experts used specially [...]
In March 2020, Hannu Rajaniemi pivoted his biotech company Helix Nanotechnologies' focus from cancer therapies to Covid-19 vaccines. The role biotech start-ups can play in a pandemic Rajaniemi originally co-founded Helix Nanotechnologies in Cambridge, Massachusetts in 2013 to develop cancer therapeutics, which was a personal mission: His mother got sick with and eventually passed due to [...]
The rapid mass testing strategy costing just £1 a day per child can get children back to school and economies up and running, according to experts. That is the small price of the rapid mass testing across schools in the UK, which is also hard on the heels of one of the world’s [...]
Covid-19 vaccines are incredibly good at preventing severe symptoms and hospitalization, but they’re probably less effective at stopping transmission. To do that, we might need a different kind of vaccine altogether. Because SARS-CoV-2 is mainly transmitted through droplets and airborne aerosols, some scientists reason that a vaccine should provide first-line protection where the virus [...]
