COVID-19, the disease resulting from SARS-CoV-2 infection, is associated with highly variable clinical outcomes that range from asymptomatic disease to death. For those with milder infections, COVID-19 can produce respiratory infection symptoms (cough, congestion, fever) and sensory phenotypes such as headache and loss of sense of smell.

In more severe cases, SARS-CoV-2 infection can affect nearly every organ and result in strokes from vascular occlusion, cardiovascular damage and acute renal failure. A substantial number of actively infected patients suffering from both mild and severe infections experience sensory-related symptoms, such as headache, visceral pain, Guillain-Barre syndrome, nerve pain and inflammation...

The first-time detection of Gravitational Waves (GW) by researchers at the Laser Interferometer Gravitational-wave Observatory (LIGO) in 2015 triggered a revolution in astronomy. This phenomenon consists of ripples in spacetime caused by the merger of massive objects and was predicted a century prior by Einstein’s Theory of General Relativity. In the coming years, this burgeoning field will advance considerably thanks to the introduction of next-generation observatories, like the Laser Interferometer Space Antenna (LISA).

With greater sensitivity, astronomers will be able to trace GW events back to their source and use them to probe the interiors of exotic objects and the laws of physics...

Researchers from the University of California, Irvine have developed a DNA enzyme—or DNAzyme—that can distinguish between two RNA strands inside a cell and cut the disease-associated strand while leaving the healthy strand intact. This breakthrough “gene silencing” technology could revolutionize the development of DNAzymes for treating cancer, infectious diseases and neurological disorders.

DNAzymes are nucleic ac...
