Take a look at the Moon through binoculars or a telescope and its clear that its been bombarded through history by space rocks. Some of the impacts are energetic enough that debris is ejected from the surface facer than the Moon’s escape velocity. Much of this rock finds its way to Earth and now, a team of researchers announce they have been simulating these events. They simulated asteroid impacts and tracked the debris that escaped the lunar surface and were surprised at just how much of the ejecta found its way to Earth.

A black hole bomb - an idea first proposed in 1969 - has now been realised in the lab as a toy model made from a rotating cylinder and magnetic coils. Studying the bomb could help us better understand real black holes.

An Austrian site occupied by humans from around 24,000 to 20,000 years ago documents a switch towards hunting reindeer for their fur, which may have helped people to endure harsh winters during the last glacial period

Those of us who paid attention to their COVID wishcasting are not the least bit surprised that measles is killing and injuring children under their watch.

The post Our Current Medical Establishment Would Have Botched COVID, The Same Way They Are Botching Measles first appeared on Science-Based Medicine.

Looking up at the night sky, it’s reasonable to believe that our Solar System is largely empty after all the only things easily visible are the planets. In reality its a cosmic shooting gallery and it’s just a matter of time before an asteroid slams into Earth. A team of scientists propose that space agencies develop a rapid-response flyby reconnaissance mission to reach potential asteroid threats within 2.5 years of detection.

Researchers in the field of exposomics explain how cutting-edge technologies are unlocking this biological archive, ushering in a new era of disease prevention and personalized medicine.

Researchers have long recognized that quantum communication systems would transmit quantum information more faithfully and be impervious to certain forms of error if nonlinear optical processes were used. However, past efforts at incorporating such processes could not operate with the extremely low light levels required for quantum communication.

Researchers have developed a novel high-energy particle detection instrumentation approach that leverages the power of quantum sensors -- devices capable of precisely detecting single particles.

The world's largest solar telescope has reached an important milestone. The data published now were obtained during the technical commissioning of the instrument.

Humans are better than current AI models at interpreting social interactions and understanding social dynamics in moving scenes. Researchers believe this is because AI neural networks were inspired by the infrastructure of the part of the brain that processes static images, which is different from the area of the brain that processes dynamic social scenes.

In examining how different countries have rolled out climate change mitigation strategies, research has found reasons to be optimistic about preserving our environment while promoting prosperity and well-being.

Innovative statistical method helps determine ideal threshold times in restricted mean survival time analyses.

A study describes a new method of recycling silicone waste (caulk, sealants, gels, adhesives, cosmetics, etc.). It has the potential to significantly reduce the sector's environmental impacts. This is the first universal recycling process that brings any type of used silicone material back to an earlier state in its life cycle where each molecule has only one silicon atom. And there is no need for the raw materials currently used to design new silicones. Moreover, since it is chemical and not mechanical recycling, the reuse of the material can be carried out infinitely.

Telescopes can have more than one sensor. Those sensors can utilize some of the same infrastructure, like lenses and mirrors, and specialize in collecting different data. A good example of this is the Inouye Solar Telescope (IST). It is the largest solar telescope in the world, with a primary mirror diameter of 4 meters. It also has five separate instruments, four of which are currently in operation. The latest of these to come online is the Visible Tunable Filtergraph (VTF), which just collected its first light according to a press release by the Max Planck Institute for Solar Research, one of the project partners.

About 380,000 years after the Big Bang, the first atoms formed. The first light of what we now see as the cosmic microwave background was released, and the primordial hydrogen and helium grew cold and dark. The cosmos entered a dark age for about 100 million years until the first stars and galaxies started to form. You could say the rise of galaxies marked cosmic morning. But star formation didn't really kick into gear for another 2-3 billion years, during what astronomers call cosmic noon. This period can be difficult to observe, but a new study gives us an unprecedented view of this epoch.

A carnivorous caterpillar species camouflages itself with dead insects so it can live safely alongside spiders, stalking their webs and stealing their prey

The Milky Way has more than 30 known satellite galaxies. The Large and Small Magellanic Clouds are the largest and most well-known; other lesser-known ones, like the Sagittarius Dwarf Galaxy, are also on the list. Astronomers think there are many more small satellites that are difficult to detect but essential in understanding the Milky Way. The Vera Rubin Observatory should help astronomers find many more of them.

Last week astronomers reported hints of biological activity on a distant planet, but a re-analysis of their data suggests the claimed molecules may not be there at all
