Europa, here we come.

In the coming years, NASA and the European Space Agency (ESA) will send two robotic missions to explore Jupiter’s icy moon Europa.

Frore Systems Airjet Mini and Airjet Pro are active cooling chips that are just 2.8mm thick and quietly suck cool air in from the top of the chip before pushing it out the sides with the aim to replace traditional fan-based solutions in ultrabooks, or be integrated into VR headsets and smartphones for improved cooling.

Yesterday we saw that cameras could clean themselves with micro-vibrations, and it happens that processors can be cooled with vibrations too as the Airjet chips are comprised of tiny membranes that vibrate at ultrasonic frequencies to generate a flow of air that enters through inlet vents in the top and transformed into high-velocity pulsating jets exiting from one side of the chip.

Scientists have developed a way to detect 3D shapes and the movements of human bodies in a room using a Wi-Fi router.

The researchers at Carnegie Mellon University in the U.S. hope that the technology may eventually replace normal cameras.

According to a recent paper published on arXiv, the team of scientists managed to make out images of people in a room through the Wi-Fi signals emitted from a normal router.

Don’t tell these engineers that they “are being exploited…” wink

Metastasisation — the spreading of cancer cells from the primary tumour into surrounding body tissues and organs — is the leading cause of death in cancer patients. Now a new study has found a potential way to stop these cancer cells from entering a person’s blood. Scientists from Israel are working to produce the world’s first preventative drug to help stop tumours that cause secondary cancer, as reported byThe Times of Israel.

Two astronauts from the International Space Station (ISS) yesterday performed the first spacewalk of the year, working on the exterior of the station as part of a long-term program to upgrade the ISS power system. The spacewalk took place on Friday, January 20, and lasted over seven hours, though one troublesome strut wasn’t bolted into place as planned.

The two astronauts performing the spacewalk were NASA astronaut Nicole Mann and Japan Aerospace Exploration Agency (JAXA) astronaut Koichi Wakata, and this was the first spacewalk for each of them.

The ISS solar arrays which provide power to the station are getting old, so in a long-term project astronauts are installing new arrays called iROSAs at an offset on top of the old arrays — allowing both sets of arrays to provide power. The aim of the spacewalk yesterday was to install two mounting platforms, which would be used to install new solar arrays later this year.

Satellite images reveal dramatic changes to California’s valleys, mountains and coastlines.

Initially, the project was supposed to take three months. But it ended up lasting a year and a half and saw many failures, breakdowns, and rewrites. The team behind the YouTube channel even made three videos before scrapping them all and going with the final version.

University of Queensland researchers have identified a pathway in cells that could be used to reprogram the body’s immune system to fight back against both chronic inflammatory and infectious diseases.

Dr. Kaustav Das Gupta and Professor Matt Sweet from UQ’s Institute for Molecular Bioscience discovered that a molecule derived from glucose in immune cells can both stop bacteria growing and dampen inflammatory responses. Dr. Das Gupta said that the finding is a critical step towards future therapeutics that train immune cells.

The research was published in Proceedings of the National Academy of Sciences (PNAS).
