Eleven science stories likely to make big news in 2023
As the COVID-19 pandemic enters its fourth year as a global health emergency, researchers will continue pushing to help make the disease manageable and ordinary. They will track hundreds of subvariants of Omicron, the highly transmissible but seemingly less lethal strain of SARSCoV-2 that dominated in 2022. Virologists will watch the virus’ evolution this year to see whether it has finally slowed or a more dangerous variant pops up, evading much of the immunity that humanity has built up to previous ones. Vaccine researchers hope to develop new shots that provide broad protection against a variety of coronaviruses.  Ano...

Was a study that created a hybrid COVID-19 virus too risky?
The objective was to tease apart whether Omicron’s spike protein explains why it is less pathogenic (meaning it causes less severe disease). The answer could lead to improved COVID-19 diagnostic tests and better ways to manage the disease, the preprint authors say. Somewhat surprisingly, the hybrid virus killed eight of 10 infected mice, whereas mice infected with Omicron got sick but did not die. This suggests the mutations that make Omicron less pathogenic must involve changes in proteins other than the spike protein, the authors say. What are critics of the study saying? They question the scientific val...

News at a glance: New gene therapy, Europe ’s drought, and a black hole’s photon ring
ARCHAEOLOGY Drought exposes ‘Spanish Stonehenge’ for study Scientists are rushing to examine a 7000-year-old stone circle in central Spain that had been drowned by a reservoir for decades and was uncovered after the drought plaguing Europe lowered water levels. Nicknamed the “Spanish Stonehenge”—although 2000 years older than the U.K. stone circle—the Dolmen of Guadalperal (above) was described by archaeologists in the 1920s. The approximately 100 standing stones, up to 1.8 meters tall and arranged around an oval open space, were submerged in the Valdecañas reservoir after the construction of a ...
