Arctic rivers provide fingerprint of carbon release from thawing permafrost

The feedback between a warming climate and accelerated release of carbon currently frozen into permafrost around the Arctic is one of the grand challenges in current climate research. A study used radiocarbon dating of carbon in four large Siberian-Arctic rivers to pinpoint the patterns of old carbon release from permafrost across northern Eurasia.

Vaccine for African swine fever may save our bacon

Wild boar can be immunized against African Swine Fever by a new vaccine delivered to the animals in their food. This is the first report of a promising inoculation against this deadly disease, which is a worldwide threat to the swine industry. The study shows immunity can be passed on via contact, but further studies need to examine how this occurs, the safety of repeated administration and its genetic stability as it is passed on.

New material also reveals new quasiparticles

Researchers have investigated a novel crystalline material that exhibits electronic properties that have never been seen before. It is a crystal of aluminum and platinum atoms arranged in a special way. This resulted in novel properties of electronic behavior for the crystal as a whole, including so-called Rarita-Schwinger fermions in its interior.

Stem cells make more ‘cargo’ packets to carry cellular aging therapies

Scientists report that adult cells reprogrammed to become primitive stem cells, called induced pluripotent stem cells (iPSCs), make tiny ‘cargo packets’ able to deliver potentially restorative or repairing proteins, antibodies or other therapies to aged cells. They say the human iPSCs they studied produced much more of the packets, formally known as extracellular vesicles, than other kinds of adult stem cells commonly used for this purpose in research.

New Trailer For ‘Spider-Man: Far From Home’ Includes Major Spoilers For ‘Avengers: Endgame’

“Bitch please, you’ve been to space.” 

Samuel L. Jackson‘s Nick Fury gets the best line by far in this new trailer for the upcoming Spider-Man: Far From Home. Bonus: It’s the most Samuel L. Jackson line ever said in any Marvel flick. 

That said, there are plenty of other great reasons to watch this, as it promises a movie that’s lighter and funnier than Avengers: Endgame but no less action-packed.

Spider-Man

There are also—as Tom Holland (minus the American accent he affects as Peter Parker) warns at the outset—some good reasons to not watch. 

Namely this: If you haven’t seen Avengers: Endgame, this will likely spoil the hell out of several big plot points from that movie. 

So, if you haven’t clicked yet, consider yourself warned. 

Here’s what’s happening in Far From Home:

Peter Parker’s relaxing European vacation takes an unexpected turn when Nick Fury suddenly shows up in his hotel room. Parker soon finds himself donning the Spider-Man suit to help Fury stop the evil Mysterio from wreaking havoc across the continent.

Jake Gyllenhaal, of course, is Mysterio. He appears to be another superhero in the trailers, and in this one it’s revealed he may have come from an alternate universe. 

Jake Gyllenhaal as Mysterio

In the Spider-Man comics Mysterio is in some respects the ultimate con man, so take all that with a grain of salt. 

If the massive publicity push behind Avengers: Endgame hasn’t left you saturated with Marvel madness yet, then get ready—Spider-Man: Far From Home is in theaters on July 2, 2019.
