Images of Mars never cease to amaze. This latest image of NASA’s Curiosity Rover captured by the Mars Reconnaissance Orbiter shows the rover as a dark speck and the end of a long trail of tracks. It was rattling along at a speed of 0.16 km/h across the Gediz Vallis Channel and was headed towards a region that could have been formed by water billions of years ago. The weather on Mars won’t allow the tracks to persist though so they are likely to last for only a few months.

Lately, there's been plenty of progress in 3D printing objects from the lunar regolith. We've reported on several projects that have attempted to do so, with varying degrees of success. However, most of them require some additive, such as a polymer or salt water, as a binding agent. Recently, a paper from Julien Garnier and their co-authors at the University of Toulouse attempted to make compression-hardened 3D-printed objects using nothing but the regolith itself.

There's no better word for this image of the Sun than Spectacular, which means something impressive, dramatic, or remarkable that creates a spectacle or visual impact. It comes from the Latin word spectaculum, which means a show, spectacle, or public exhibition. Ancient Romans would agree with the word choice if you could somehow show it to them.

An Ultra-Diffuse Galaxy Found With Almost No Dark Matter

A recent study has unraveled some of the secrets concealed within the entangled web of quantum systems.

Historically, small molecule drugs have been precisely designed down to the atomic scale. Considering their relatively large complex structures, nanomedicines have lagged behind. Researchers argue this precise control should be applied to optimize new nanomedicines.

Astronomers have discovered that super-Earth exoplanets are more common across the universe than previously thought. While it can be relatively easy to locate worlds that orbit close to their star, planets with wider paths can be difficult to detect. Still, researchers estimated that for every three stars, there should be at least one super-Earth present with a Jupiter-like orbital period, suggesting these massive worlds are extremely prevalent across the universe.

Researchers have developed a new therapy that can be injected intravenously right after a heart attack to promote healing and prevent heart failure. The therapy both prompts the immune system to encourage tissue repair and promotes survival of heart muscle cells after a heart attack. Researchers tested the therapy in rats and showed that it is effective up to five weeks after injection.

Many products in the modern world are in some way fabricated using computer numerical control (CNC) machines, which use computers to automate machine operations in manufacturing. While simple in concept, the ways to instruct these machines is in reality often complex. A team of researchers has devised a system to demonstrate how to mitigate some of this complexity.

Dimethyl Sulfide (DMS) has been in the news again, this time for its discovery in the atmosphere of the hycean world K2-18b as a potential biosignature. In an interesting twist, astronomers have also detected DMS in comets and in giant molecular clouds. It shows there must be an abiotic way for this chemical to be produced. A team of researchers have studied DMS and developed different gas phase reactions that could produce this chemical and explain its presence that doesn’t require life.

Hackers may be able to garble the output of programs running on quantum computers, leaving other people with unknowingly incorrect results - but thankfully, there is a fix

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.
