NASA’s Perseverance Rover Is The Inspiration We Need Right Now

NASA’s Perseverance rover is on track to launch this summer, and when it does, it will carry the names of nearly 11 million people to Mars.

Earlier this month, as communities around the country locked themselves down in an effort to slow the spread of the novel coronavirus, a team at Kennedy Space Center in Florida started the process of packing the rover for launch. They lowered and locked the rover’s mast, stowed away its robotic arm, and retracted its wheels. But first, they fixed the rover up with the ultimate vanity license plate.

Last year, NASA asked people around the world to submit their names to its “Send Your Name to Mars” program, and 10,932,295 people responded...

Study supports contested 35-year-old Predictions, shows that observable Novae are just ‘Tip of the Iceberg’

Almost 35 years ago, scientists made the then-radical proposal that colossal hydrogen bombs called novae go through a very long-term life cycle after erupting, fading to obscurity for hundreds of thousands of years and then building back up to become full-fledged novae once more. A new study is the first to fully model the work and incorporate all of the feedback factors now known to control these systems, backing up the original prediction while bringing new details to light. Published this week in the journal Nature Astronomy, the study confirms that the novae we observe flashing throughout the universe represent just a few percent of these cataclysmic variables, as they are known, with the rest “hiding” in hibernation.

“We’ve now quantified the suggest...

How Trans Fats Assist Cell Death

Trans-Fatty acids facilitate DNA damage-induced apoptosis through the mitochondrial JNK-Sab-ROS positive feedback loop

DOI: https://doi.org/10.1038/s41598-020-59636-6

Tohoku University researchers in Japan have uncovered a molecular link between some trans fats and a variety of disorders, including cardiovascular and neurodegenerative diseases. Their findings, published in the journal Scientific Reports, implicate their role in enhancing a mitochondrial signalling pathway that leads to programmed cell death.

“Accumulating evidence has associated the consumption of trans-fatty acids with various diseases, including some lifestyle d...

An Organic Solar Cell with 25% Efficiency

The ‘best conversion performance in the world in a dark room’ is how the developers of a new organic PV device have described it. Such cells could be used as a wireless source of energy for IoT applications or in gadgets such as temperature-humidity and motion sensors.

Eight months ago, a state-funded French research institute and Japanese textiles company Toyobo announced they would join forces to develop superior organic solar cells for indoor applications. The partnership, the French organization said at the time, was aimed at developing thin, flexible solar cells which could function where conventional, inorganic solar cells could not.

The new energy technologies and nanomaterials (Liten) division of the French Alternative Energies and Atomic Energy Commission and To...
