Researchers at UCLA and Stanford University have developed a secure, noninvasive, one-touch technology using hydrogel-coated chemical sensors and a signal-interpretation framework. It can present detailed information about an individual's blood composition — such as metabolites, hormones, nutrients, and pharmaceuticals, as well as blood oxygen — all through the press of a finger.

After a long summer break, Friday Science Jokes is back at your service. Even during the hot holidays some of us were working hard and we all know that science could be a hard thing to do. No matter if you are still learning, teaching, or conducting research and experiments, you should never forget the creative power of a good laugh. Thank goodness science lends itself to some pretty good jokes. Below you can enjoy some of them.

A new analysis of seismic data from the InSight mission to Mars has revealed some surprises. The first: the top 300 meters of the subsurface beneath the InSight landing site near the Martian equator contains little to no ice. "We find that Mars' crust is weak and porous, the sediments are not well-cemented, and there's no ice or not much ice filling the pore spaces," said geophysicist Vashan Wright of the Scripps Institution of Oceanography at the University of California San Diego. Wright and co-authors published the U.S. National Science Foundation-supported analysis in Geophysical Research Letters.

Salamanders are remarkable creatures. If one of these amphibians loses a finger, it grows back. Furthermore, if you chop away a piece of heart or spinal cord, it will regenerate. Perhaps most impressively, they can even regrow a leg bitten off by a hungry predator.

One of the most famous salamander species is the axolotl (Ambystoma mexicanum), which is found in lakes near Mexico City.

The axolotl is a veritable Peter Pan of salamanders. Even the 30-centimetre-long reproductive adult retains features of its youthful phase throughout its lifecycle.

The prominent gills protruding from the back of its head are retained from the axolotl's larval phase. The fact that it never leaves the water throughout its life is unusual for an amphibian.

NASA is preparing for the first integrated test mission of its deep space exploration systems today – 29.08.2022. The name of the mission is Artemis 1 and is the first of a series of planned launches, which hope to achieve the first manned landing on the surface of the Moon since 1972's Apollo 17. Artemis 1 is going to be an uncrewed flight test with mannequins. The main objective is to test the heating shield systems, NASA's next-generation spacesuits, and radiation levels. If the mission is successful, Artemis 2 will take four astronauts near the moon in 2024. After that, Artemis 3 will take a crewed spacecraft for a moon landing. Finally, Artemis 4 will fly to a space station near the moon. NASA aspires that the Artemis expedition will enable a crewed trip to Mars in the following years.
