New gene variants associated with increased COVID-19 risk

New gene variants associated with increased COVID-19 risk

BiomedicineGenetics

By Rosa García-Verdugo

Since the beginning of the COVID-19 pandemic, there were hints at particular genes which increased some people’s susceptibility to get infected and the severity of illness once infected. Now, an international study (nearly 3500 researchers from 25 countries) on more than 45000 people infected with SARS-CoV-2, showed a link between 13 genetic variants and the […]

Mysterious space object has dual personality A space object called 2005 QN173 is both a comet and an asteroid, according to a study set for publication in The Astrophysical Journal Letters. The object is icy, leaves a dust trail like a comet and has an orbit of an asteroid, circling the sun on the outer […]

Plasmonic cavities formed by metallic surfaces are nanostructures that confine light to dimensions far smaller than the free-space wavelength, as they mix optical fields with electronic excitations. I t was not until the 1990s, with the appearance of accurate and reliable nanofabrication techniques, that plasmonics blossomed. It was found then that local fields around nanostructures […]

By José Ramón Alonso

A significant portion of an organism’s genome is non-coding; that is, it does not carry information to make proteins. Part of the non-coding DNA is transcribed into functional non-coding RNA molecules (e.g., transfer RNA, ribosomal RNA and regulatory RNA). Other functions of non-coding DNA include transcriptional and translational regulation of protein coding sequences, nuclear scaffold […]

Deep canyons on Mars created by ancient floods Deep canyons and valleys on Mars were likely carved by flooding caused by overflowing lakes billions of years ago. “Our results show that many Martian valleys are in fact more analogous to catastrophic floods on Earth, such as those that shaped the northwest United States at the […]

The eastern North American population of monarch butterflies are famous for their annual, multi-generational, round-trip migration from the oyamel fir forests of Central Mexico through the United States to Canada and back. Sadly, the population of monarch butterflies is declining, and the future of the monarch migratory phenomenon is uncertain. Scientists can study migrations by […]

Humans walked the Americas earlier than once thought Archaeologists have uncovered footprints in New Mexico that date back as much as 23,000 years, suggesting humans traversed the Americas much earlier than previously believed. The 61 footprints, described in the journal Science, were found near a dry lake bed and hint that humans were trying to […]
