On the surface, Ebola and the flu might not seem all that similar — one can cause organ failure or death, while the other usually just makes you feel really crummy — but they actually have the same underlying cause: an RNA-based virus.
That’s the type of virus behind some of the most common — and deadly — illnesses in the world, and researchers have just discovered a way to use the powerful gene-editing technology CRISPR in the fight against them.
On Thursday, a team lead by researchers from Harvard and MIT’s Broad Institute published a study in the journal Molecular Cell detailing their creation of CARVER (Cas13-Assisted Restriction of Viral Expression and Readout), a system that utilizes the CRISPR enzyme Cas13, which “naturally targets viral RNA in bacteria,” according to a Broad Institute press release.
Engineers at the University of California San Diego have developed a way to build soft robots that are compact, portable and multifunctional. The advance was made possible by creating soft, tubular actuators whose movements are electrically controlled, making them easy to integrate with small electronic components.
As a proof of concept, engineers used these new actuators to build a soft, battery-powered robot that can walk untethered on flat surfaces and move objects. They also built a soft gripper that can grasp and pick up small objects.
The team, led by UC San Diego mechanical and aerospace engineering professor Shengqiang Cai, published the work Oct. 11 in Science Advances.
If SpaceX wants its massive next-generation spacecraft to reach the moon and planets beyond, CEO Elon Musk says it’ll need to be refueled in orbit around Earth – and NASA wants to know more.
Now in the prototype and early test flight phase, Starship is a stainless steel crewed craft that will launch atop a Super Heavy booster. But because of its size and potentially heavy payloads – like dozens or hundreds of astronauts – in the future, it will need to be refueled in orbit around Earth before it begins longer voyages.
SpaceX, Musk said, is developing the technologies necessary to dock two Starships together in orbit – one without much in the way of crew or payloads – and transfer fuel to the one venturing beyond low-Earth orbit.
Time for my yearly proselytizing for PBS UK’s Rough Science. Awesome educational show where a bunch of scientists are dumped on an island and have to work together to make something crazy out of local scavenged materials.
The group is taken to a disused prison on the island where they have to determine the longitude and latitude of the island, create a radio from a saucepan and create an insect repellent.
It’s not yet clear whether a theory that unites general relativity and quantum mechanics would permit time travel.
Lex Fridman, a postdoctoral associate at the MIT AgeLab, had a great conversation with Peter Norvig, an American computer scientist, teacher and author.

How is a Unitary Subject of Experience Possible? ~ Philosopher David Pearce.
Is Australia conscious? How would 86 billion classical neurons (mind dust) come together to form a unitary subject of experience?
The answer is related to the binding problem of consciousness.

A stroke occurs when blood flow to an area of the brain is suddenly cut off. The brain cells get deprived of oxygen and begin to die quickly. Having a stroke is a scary thought, but you can be mindful of your health to reduce the chances of having one.
