Fermilab and partners achieve sustained, high-fidelity quantum teleportation

Posted: 31 Dec 2020 09:20 AM PST

Quantum information ‘teleported’ at Fermilab, Caltech represents step toward quantum internet Aviable quantum internet—a network in which information stored in qubits is shared over long distances through entanglement—would transform the fields of data storage, precision sensing and computing, ushering in a new era of communication. This month, scientists at Fermi National Accelerator Laboratory—a U.S. Department […]

Gum disease-causing bacteria borrow growth molecules from neighbors to thrive

Posted: 31 Dec 2020 09:16 AM PST

The human body is filled with friendly bacteria. However, some of these microorganisms, such as Veillonella parvula, may be too nice. These peaceful bacteria engage in a one-sided relationship with pathogen Porphyromonas gingivalis, helping the germ multiply and cause gum disease, according to a new University at Buffalo-led study. The research sought to understand how […]

NIH study uncovers blood vessel damage and inflammation in COVID-19 patients’ brains but no infection

Posted: 31 Dec 2020 08:51 AM PST

Results from a study of 19 deceased patients suggests brain damage is a byproduct of a patient’s illness. In an in-depth study of how COVID-19 affects a patient’s brain, National Institutes of Health researchers consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly […]

Allergists offer reassurance regarding potential allergic reactions to COVID-19 vaccines

Posted: 31 Dec 2020 08:50 AM PST

Reports of possible allergic reactions to the COVID-19 vaccines produced by Pfizer-BioNTech and Moderna, both recently approved for emergency use by the U.S. Food and Drug Administration (FDA), have raised public concern. A team of experts led by allergists at Massachusetts General Hospital (MGH) has now examined all relevant information to offer reassurance that the […]

Blood vessel cells implicated in chronic inflammation of obesity

Posted: 31 Dec 2020 08:50 AM PST

When fat cells in the body are stuffed with excess fat, the surrounding tissue becomes inflamed. That chronic, low-level inflammation is one of the driving factors behind many of the diseases associated with obesity. Now, UT Southwestern scientists have discovered a type of cell responsible, at least in mice, for triggering this inflammation in fat […]

Scientists explore deficits in processing speed in individuals with spinal cord injury

Posted: 31 Dec 2020 08:49 AM PST

A team of rehabilitation researchers has studied processing speed deficits in individuals with spinal cord injury (SCI), comparing their brain activation patterns with those of healthy age-matched controls, and older healthy individuals. They found that the SCI group and older controls had similar activation patterns, but the SCI group differed significantly from their age-matched controls. […]
