In 2022-2023, an outbreak of monkeypox, now known as mpox (caused by the monkeypox virus or MPXV) led to 87,000 human cases in 170 countries. Most cases were reported outside the usual areas in which the virus circulates. Since the outbreak began, surveillance of the virus has been stepped up in Europe, with nearly 5,000 cases being reported in France.

While the incidence of influenza-associated neuropsychiatric events in children in the United States is unknown, the controversy over the use of a common antiviral medication typically administered to treat flu in children has sparked concern among parents and medical professionals alike.

Researchers have discovered the molecular mechanisms by which the human immunodeficiency virus (HIV) becomes resistant to Dolutegravir, one of the most effective, clinically used antiviral drugs for treating HIV. Their findings reveal how changes to the 3D structures of integrase, an HIV protein, can lead to Dolutegravir resistance and how other compounds may be able to overcome this resistance.

The new carbon nanotube sensor design resembles a molecular toolbox that can be used to quickly assemble sensors for a variety of purposes -- for instance for detecting bacteria and viruses.

Researchers have found that people with longer-term COVID-19 symptoms including brain fog showed reduced performance in tasks testing different mental processes up to two years after infection with the virus.

The material record that currently exists on the moon is rapidly becoming at risk of being destroyed if proper attention isn't paid during the new space era, scientists say. They propose a new scientific subfield: planetary geoarchaeology, the study of how cultural and natural processes on Earth's moon, on Mars and across the solar system may be altering, preserving or destroying the material record of space exploration.

Machine-learning system effectively predicts emergence of prominent variants.

A newly described type of chemistry in fungi is both surprisingly common and likely to involve highly reactive enzymes, two traits that make the genes involved useful signposts pointing to a potential treasure trove of biological compounds with medical and chemical applications. It was also nearly invisible to scientists until now.

A team has modeled the early impact history of Venus to explain how Earth's sister planet has maintained a youthful surface despite lacking plate tectonics. The team compared the early collision histories of the two bodies and determined that Venus likely experienced higher-speed, higher-energy impacts creating a super-heated core that promoted extended volcanism and resurfaced the planet.

Researchers look at water in galaxies, its distribution and in particular its changes of state from ice to vapor, as important markers indicating areas of increased energy, in which black holes and stars are formed. A new study has now revealed the distribution of water within the J1135 galaxy, which is 12 billion light years away and formed when the Universe was a 'teenager', 1.8 billion years after the Big Bang . This water map, with unprecedented resolution, is the first ever to be obtained for such a remote galaxy. The map can help scientists to understand the physical processes taking place within J1135 and shed light on the dynamics, still partially unclear, surrounding the formation of stars, black holes and galaxies themselves.

Astronomers have found the possible 'sibling' of a planet orbiting a distant star. The team has detected a cloud of debris that might be sharing this planet's orbit and which, they believe, could be the building blocks of a new planet or the remnants of one already formed. If confirmed, this discovery would be the strongest evidence yet that two exoplanets can share one orbit.

People who contract COVID-19 but never develop symptoms -- the so-called super dodgers -- may have a genetic ace up their sleeve. They're more than twice as likely as those who become symptomatic to carry a specific gene variation that helps them obliterate the virus, according to a new study.

In a first for white dwarfs, the burnt-out cores of dead stars, astronomers have discovered that at least one member of this cosmic family is two faced. One side of the white dwarf is composed of hydrogen, while the other is made up of helium.

Parasitic hairworms manipulate the behavior of their hosts in what's sometimes called 'mind control.' A new study reveals another strange trait shared by different hairworm species: they're missing about 30% of the genes that researchers expected them to have. What's more, the missing genes are responsible for the development of cilia, the hair-like structures present in at least some of the cells of every other animal known.

Astronomers have found evidence that some stars boast unexpectedly strong surface magnetic fields, a discovery that challenges current models of how they evolve.

A team has found that NASA's Juno spacecraft orbiting Jupiter frequently encounters giant swirling waves at the boundary between the solar wind and Jupiter's magnetosphere. The waves are an important process for transferring energy and mass from the solar wind, a stream of charged particles emitted by the Sun, to planetary space environments.

In the search for extraterrestrial intelligence, alien radio signals would be swamped by interference from radio sources on Earth. To confirm, researchers point away from the source and then back. If it's still there, it may be interesting. Researchers have come up with a new method that looks for evidence the signal has passed through the interstellar medium. The technique will boost confidence in any candidate signal discovered in the future.

The NASA/ESA Hubble Space Telescope has captured a monster in the making in this observation of the exceptional galaxy cluster eMACS J1353.7+4329, which lies about eight billion light-years from Earth in the constellation Canes Venatici. This collection of at least two galaxy clusters is in the process of merging together to create a cosmic monster, a single gargantuan cluster acting as a gravitational lens.
