Mankind has no choice but to colonise Mars if human beings are to have a future, physicist and science populariser Brian Cox has said. Currently a professor at Manchester University in the UK, Cox has found global fame as a presenter of documentaries, taking millions of viewers on virtual journeys through the galaxy.

This dude was A+OK in my book. Yeah you knew Jobs, yeah you knew Minsky, but did you ever know even the name of the guy who convinced me to become a programmer? Rest In Eternal Peace. #RIP

Before going to space, should we solve the problems here, on Earth?

Whenever we speak about human presence in space to a general audience, and quite often when we talk with specialists as well, we have to hear the Great Objection:” Before going to space, we have to solve our problems here, on the Earth”.

As soon as we reason about it we understand that the Objection is in fact a general dialectic scheme, which consists in changing the topic, pretending that the alternative is more important and urgent and so avoiding to reply to what the speaker has said. In short, it is a sort of quite-another-ism: “The problem is quite another, the cause is quite another…”.

Rich experiences—from play to the arts and relationships—fundamentally shape a young child’s development.

Up to four spacewalks are planned to finish a space station power upgrade, clearing decks for early Crew Dragon return in early August.

In 2016, fluid broke into the cracks of a fault system, setting off a four-year-long swarm of mini earthquakes.

SpaceX has at long last transported its fifth full-scale Starship prototype to a nearby launch pad, kicking off a week of busy pre-test preparations while the sixth rocket is already nipping at its heels.

Starship SN5’s move to the pad ends the longest gap between full-scale prototype testing since Starship Mk1 was destroyed in November 2019, a partially-expected failure that began a more than three-month period of infrastructure upgrades. The first upgraded Starship (SN1) rolled to the pad on February 25th, followed by SN3 on March 29th and SN4 on April 23rd, indicative of a fairly consistent monthly cadence of Starship production (and destruction).

Almost exactly two months after its predecessor headed from the factory to SpaceX’s Boca Chica, Texas launch facilities, Starship SN5 has taken its place on a brand new launch mount. The cause of that month-long delay is fairly simple. When Starship SN4 exploded on May 29th, it damaged the existing launch mount and some additional ground support equipment (GSE), forcing SpaceX to scrap the destroyed mount and build a new one from scratch. In a matter of weeks, SpaceX’s crack team of pad engineers and technicians have done exactly that.

Approach could lead to new ways to treat epilepsy, depression, and Alzheimer’s disease.

While some cholesterol is a healthy thing for properly functioning cells, too much of it can cause blockages in the arteries and heart trouble, along with a host of other negative health outcomes. Scientists have discovered a new mechanism by which a “bad” type of cholesterol gains entry to the cells, identifying a pair of proteins that work like an entry tunnel. These proteins show promise as new targets for drugs that could lower cholesterol levels in the blood to help prevent disease.

The discovery made by an international team of researchers was only possible thanks to advances in imaging technology that enabled them to inspect proteins at a near-atomic level. In this case, the team were investigating the role two proteins, NPC1 and NPC2, play in transporting low-density lipoprotein (LDL) cholesterol, often referred to as “bad” cholesterol, into our cells.

“Before 2013 we often had to theorise about how membrane proteins worked and how they functioned, but now we can actually see them, and seeing is believing,” says study author Prof Rob Yang from the UNSW in Australia. “We were able to look at the NPC1 and NPC2 proteins and see exactly the role they play in transporting this LDL cholesterol into the cell.”
