466-million-year-old meteors raining down on Earth — When the solar system was in its rebellious stage about 466 million years ago, two massive asteroids collided in the asteroid belt between Mars and Jupiter, sending tiny pieces of shrapnel flying all over the solar system.
After examining bits of crystals that fell to Earth just before the collision, an international team of scientists has learned that space rocks that only enter our atmosphere rarely now were much more prevalent back in the day. And stuff from that big breakup is still raining down on us.
~ So we’re still seeing the effects of an event that took place almost 500 million years ago.
In 1995, Carl Sagan predicted manufacturing jobs gone & no control over our political lives — Did Carl Sagan really warn about a time in the future when manufacturing jobs would slip away, when the average person would have virtually no control over their political lives, and when we would all cling to superstitions? Yes, Sagan did. And plenty of people are worried that Carl was talking about our era. The passage comes from Sagan’s book Demon-Haunted World: Science as a Candle in the Dark, first published in 1995.
~ Go him. I just wish he’d been wrong.
Super-powerful laser — A Czech and British research team says their ‘super laser’ is capable of an average power output of over 1000 watts, making it ‘10 times as powerful‘ as other lasers of its type.
~ There have been more powerful, but that’s peak pulses. This has a powerful average output, which is the important bit. Bzzt.
Australian biometric passports — Australia has begun the search for technology companies that could provide biometric systems, such as facial, iris and fingerprint recognition for border control. Head of border security John Coyne said it could be a “world first.” But critics have questioned the privacy implications of such a system.
~ Surely it’s not that hard to figure out who desperately needs asylum and safety and therefore should be turned back?
Spanish scientists developed a prototype 3D printer capable of printing functional human skin — It could be used for transplant patients, as well as an ethical alternative to animal testing. The so-called bioprinter uses special ‘ink’ consisting of human cells and other biological components to reproduce the natural structure of the skin, including the external epidermis and the deeper dermis layer.
~ Surely it could add tattoos?
Lamp glows 80 hours on seawater — There are plenty of legitimate reasons to prepare for the end of civilisation as we know it (and now many of them have Trump in the title), and if the world’s supply of batteries ever runs out, you’ll be glad you had this emergency LED lamp tucked away in your doomsday shelter.
Hitachi Maxell’s Mizusion lamp for goes for about three days on a mix of salt and water. The ingredients work alongside oxygen in the air and a replaceable magnesium ‘power bar’ to create positive and negative electrodes, which in turn generates electricity.
~ Just make sure you have a seaside apocalypse.
Coffee’s gene-fueled future — This just drew nearer, now that scientists have sequenced the genome of the Coffea arabica coffee plant – the species that makes up the vast majority of global production – and made the data public. That means the world is in for a coffee renaissance, as breeders use the information to develop new plant varieties.
~ Banana with that?
