After COVID vaccination, it usually takes weeks for our bodies to develop protective antibody responses. Imagine, however, a vaccine that speeds up the production of antibodies against SARS-CoV-2, the virus that spreads COVID-19.

A research team led by Rong Hai, an associate professor of microbiology and plant pathology at the University of California, Riverside, has developed such a vaccine by using preexisting immunity to a separate virus (the influenza virus) to help kickstart the process of making antibodies against SARS-CoV-2.

“Any delay in the immune response to SARS-CoV-2 means there is some time when people are left poorly protected against the virus,” Hai said...

Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is ‘eating’ its host galaxy to death.

The international team, led by the University of Cambridge, used the NASA/ESA/CSA James Webb Space Telescope (JWST) to detect the black hole, which dates from 400 million years after the big bang, more than 13 billion years ago. The results, which lead author Professor Roberto Maiolino says are “a giant leap forward,” are reported in the journal Nature.

That this surprisingly massive black hole — a few million times the mass of our Sun — even exists so early in the universe challenges our assumptions about how black holes form and grow...

A new study reported that SARS-CoV-2, the virus that causes COVID, can infect dopamine neurons in the brain and trigger senescence—when a cell loses the ability to grow and divide. The researchers from Weill Cornell Medicine, Memorial Sloan Kettering Cancer Center, and Columbia University Vagelos College of Physicians and Surgeons suggest that further research on this finding may shed light on the neurological symptoms associated with long COVID, such as brain fog, lethargy, and depression.

The findings, published in Cell Stem Cell on Jan...

Researchers at the University of Basel have built a quantum memory element based on atoms in a tiny glass cell. In the future, such quantum memories could be mass-produced on a wafer.

It is hard to imagine our lives without networks such as the internet or mobile phone networks. In the future, similar networks are planned for quantum technologies that will enable the tap-proof transmission of messages using quantum cryptography and make it possible to connect quantum computers to each other.

Like their conventional counterparts, such quantum networks require memory elements in which information can be temporarily stored and routed as needed...
