The team from Oxford University and British-Swedish biotech firm AstraZeneca began injecting doses of vaccine Vaxzevria into patients in April 2020. It's approved for use in almost 100 countries and forms the backbone of the World Health Organization's COVAX initiative, which aims to provide equitable access to vaccines across the globe. However, as CNET reports, the vaccine has suffered setbacks. Miscommunications with the U.S. Food and Drug Administration and dosing mistakes in clinical trials eroded confidence in...
Scientists, industry experts, and policymakers will discuss the latest issues surrounding space debris in a four-day conference beginning April 20. The European Space Agency will conduct the eighth European Conference on Space Debris from Darmstadt, Germany, at which they will exchange research and attempt to determine solutions to the problem of 129 million objects larger than a millimeter in orbits around Earth.

Researchers are developing wearable devices to transform the way we monitor, diagnose and treat acute and chronic conditions, including COVID-19, Tech Xplore reports. There are a variety of devices being developed, including tattoos, contact lenses, and clothing, that can monitor a range of health signals and provide real-time data about our bodies. In an article published in Nature Electronics, researchers suggest that this data could help diagnose and treat COVID-19.

With a simple artificial nervous system now able to mimic human responses to light, scientists are learning more about how to program such technology for use in medical robotic prostheses, Tech Xplore reports. Similar to the way the human hand reacts to a hot surface, artificial nervous systems can react to their environment automatically. Now, researchers seek to program artificial neurons to respond to external stimuli consciously.

A genetic analysis of the most widespread reef coral in the Indo-Pacific revealed that rather than being a single species (Pachyseris speciosa), it is actually four distinct species of coral, researchers report in Current Biology. The results suggest other corals thought to be a single species may be more diverse than researchers realized, and understanding which coral species foster biodiversity and how those corals behave is vital to taking care of them, reports ScienceNews. In the lab, coral...

NASA helicopter Ingenuity was scheduled to take the first powered, controlled flight on another planet today, but is on hold until at least April 14, Phys.org reports. A test of Ingenuity's 1.8-kilogram rotors on Friday showed a potential problem. "The helicopter team is reviewing telemetry to diagnose and understand the issue," NASA said in a statement. "Following that, they will reschedule the full-speed test." NASA noted the copter is "safe and healthy" and...
Biologists have created a synthetic cell with only the bare minimum number of genes it needs to live and reproduce in a lab, reports CBC's Quirks & Quarks. "What we have is an organism that is right now as simple as anything that can live on the planet," said John Glass, a professor of synthetic biology at the J. Craig Venter Institute in California. Mr. Glass has obviously not met my friend Bill.

The asteroid impact 66 million years ago may have wiped out 75 percent of all life including the dinosaurs, but it set the stage for the creation of rainforests, says a new study by geologist and paleontologist Carlos Jaramillo and his colleagues. The result of the post-impact settling of dust, after several million years of evolution, was the dense, diverse tropical rainforests we know today, according to the report. The vast clouds of minerals ejected onto the landscape by the...
The Crab Nebula's pulsar, located 6,500 light-years away in the constellation of Taurus and formed in a supernova whose light is believed to have reached Earth in 1054, is among the brightest pulsars in the sky. Dr. Teruaki Enoto from the RIKEN Cluster for Pioneering Research and colleagues, tracking the Crab pulsar simultaneously with X-ray and radio telescopes, made fascinating observations published in the journal Science. “Out of more than 2,800 pulsars cataloged, the Crab pulsar is...
Neuralink released footage today appearing to show a monkey playing a video game after getting brain-chip implants, Reuters reports. The three-minute video by Neuralink, which Elon Musk co-founded in 2016, shows Pager, a male macaque with chips embedded on each side of its brain, playing Mind Pong. He reportedly controls the paddle by thinking about moving his hand up or down. "First @Neuralink product will enable someone with paralysis to use a smartphone with their mind faster...
