Scientists have devised a novel approach to halting the spread of SARS-CoV-2, the virus that causes COVID-19. The researchers engineered a completely synthetic, production-ready molecule that straitjackets the crucial SARS-CoV-2 machinery that allows the virus to infect our cells. In an aerosol formulation they tested, these molecules could be self-administered with a nasal spray or inhaler.
New detailed observations reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Weighing in at 25 Earth-masses, and slightly smaller than Neptune, this exoplanet’s existence is at odds with the predictions of leading planet formation theories.
Olfactory support cells, not neurons, are vulnerable to novel coronavirus infection.
One in 11 flowers carries disease-causing parasites known to contribute to bee declines, according to a new study that identifies how flowers act as hubs for transmitting diseases to bees and other pollinators.
The European Southern Observatory’s Very Large Telescope (ESO’s VLT) has taken the first ever image of a young, Sun-like star accompanied by two giant exoplanets. Images of systems with multiple exoplanets are extremely rare, and — until now — astronomers had never directly observed more than one planet orbiting a star similar to the Sun. The observations can help astronomers understand how planets formed and evolved around our own Sun.
Newfound bacteria that oxidize manganese help explain the geochemistry of groundwater. The finding ends a century-long search for microbes that live on manganese.
Students can hide their ignorance and answer questions correctly in an exam without their lack of knowledge being detected by teachers — but only in the quantum world.
The nearest exoplanets to us provide the best opportunities for study, including searching for evidence of life outside the Solar System. Astronomers have now detected a system of super-Earth planets orbiting the nearby star Gliese 887, the brightest red dwarf star in the sky. The newly discovered super-Earths lie close to the red dwarf’s habitable zone, where water can exist in liquid form.
A new study has shown that not all saber-tooths were fearsome predators.
Astronomers have discovered the second-most distant quasar ever found. It is the first quasar to receive an indigenous Hawaiian name, Poniua’ena. Data show the supermassive black hole powering Poniua’ena is surprisingly massive, challenging current theories of how supermassive black holes formed and grew in the young universe.
An extraordinary asteroid with comet-like features has researchers puzzled.
New research finds that an anticipated rise in carbon dioxide concentrations in our indoor living and working spaces by the year 2100 could lead to impaired human cognition.
Despite the near-universal assumption of individuality in biology, there is little agreement about what individuals are and few rigorous quantitative methods for their identification. A new approach may solve the problem by defining individuals in terms of informational processes.
The mass extinction at the end of the Permian Period 252 million years ago — one of the great turnovers of life on Earth — appears to have played out differently and at different times on land and in the sea, according to newly redated fossils beds from South Africa and Australia.
Dineobellator notohesperus lived 67 million years ago.
