SpaceX’s Falcon 9 rocket and Crew Dragon arrive at Cape Canaveral ahead of key test for crew flight
Posted by Genevieve Klien in category: space travel
SpaceX’s facility at Cape Canaveral just received a crucial new delivery: a Falcon 9 rocket and Crew Dragon capsule that it will be using for an upcoming in-flight abort test. This test, which will demonstrate the spacecraft and launch system’s ability to abort the launch mid-flight in case of any emergencies, is an important and necessary step before SpaceX can fly Crew Dragon with any actual people on board.
This test will replicate a “worst-case scenario” of sorts, by staging a crew capsule separation at the point of “Max Q,” which is the part of the launch where the rocket is exposed to the most severe atmospheric forces prior to making it to space. At this point during the abort test, the Crew Dragon will show that it can detach from the Falcon 9 rocket and propel itself away to a safe distance in order to protect the astronauts on board.

If you thought Cambridge Analytica had scary tech, wait until you see this. A new form of AI modelling promises accurate simulation of the behaviour of entire cities, countries and one day perhaps, the world.

The inability of scientists to create a theory of quantum gravity arises from long-standing tensions between general relativity and quantum mechanics. There have been few approaches with any success. In this video, Fermilab’s Dr. Don Lincoln explains one of the few promising ideas, called loop quantum gravity.

Printed electronics open way for electrified tattoos and personalized biosensors
Posted by Shane Hinshaw in categories: biotech/medical, electronics
Electrical engineers at Duke University have devised a fully print-in-place technique for electronics that is gentle enough to work on delicate surfaces including paper and human skin. The advance could enable technologies such as high-adhesion, embedded electronic tattoos and bandages tricked out with patient-specific biosensors.
The techniques are described in a series of papers published online July 9 in the journal Nanoscale and on October 3 in the journal ACS Nano.
“When people hear the term ‘printed electronics,’ the expectation is that a person loads a substrate and the designs for an electronic circuit into a printer and, some reasonable time later, removes a fully functional electronic circuit,” said Aaron Franklin, the James L. and Elizabeth M. Vincent Associate Professor of Electrical and Computer Engineering at Duke.

CRISPR flies have been gene edited so they can eat poison
Posted by Genevieve Klien in categories: biotech/medical, food, genetics
Scientists at the University of California, Berkeley have used the CRISPR gene-editing tool to give fruit flies an evolutionary advantage they’ve never had before. By making just three small changes to a single gene, the team gave the flies the ability to effectively eat poison and store it in their bodies, protecting themselves from predators in the process.
Milkweed is a common plant that’s toxic to most animals and insects – but the monarch butterfly flies in the face of that plant’s defenses. The bug has evolved the ability to not only thrive on the poisonous plant, but turn it to its own advantage. It stores the toxins in its body, making it poisonous to any predators that might try to eat it.
And now, the UC Berkeley researchers have given fruit flies that ability for the first time. CRISPR has been used to edit the genes of insects, mammals and even humans, but the team says this is the first time a multicellular organism has been edited to endow it with new behaviors and adaptations to the environment. In this case, that means a new diet and a new defense mechanism against predators.
