On Monday, UCLA scientists announced in the journal “eNeuro” that they were able to transplant the memories of one group of snails to another group. In the experiment, they inserted ribonucleic acid from the first group into the later, which ignited behavioral, long-term memories.

There are potentially active volcanoes all over the West and Alaska as well as Hawaii, and about 50 are considered high priorities for monitoring. Here is where to find them.

In a paper published Monday in the journal Proceedings of the National Academy of Sciences, researchers demonstrated that the virus could infect human cells as well as the cells of cats and chickens. Even though PDCoV appears to be limited to pigs at the moment, scientists suspect that its sudden appearance in 2012 occurred as a result of a rapid “host switching” event in which the virus adapted to infect pigs, possibly from birds. It causes diarrhea and vomiting in pigs and can be fatal, especially in nursing young. The virus’s probable history, coupled with some specific aspects of how it infects cells, has scientists worried that it could become a threat to human health.

Quantum theory is based heavily on probabilities, since measuring a quantum system doesn’t produce the same outcome every time, but instead yields one of many outcomes that each occur with a certain probability. Now in a new paper, physicists have presented a new quantum probability rule for assigning probabilities to measurement outcomes, or events, that essentially combines two of the most important quantum probability rules (the Born rule and the wave function collapse rule) into one.

The physicists, Sally Shrapnel, Fabio Costa, and Gerard Milburn, at The University of Queensland in Australia, have published a paper on the new quantum probability rule in the New Journal of Physics.

One of the most important probability rules in quantum theory is the Born rule, which gives the probability that a measurement yields a certain event. However, things get a little bit more complicated when predicting consecutive events. Although in classical scenarios it’s possible to assign joint probabilities to consecutive events using conditioning, in quantum scenarios this is not possible since each measurement necessarily disturbs the system. So in quantum mechanics, the state must be updated with this new information after every measurement.

Sometimes, scientists have the answers all along—they just don’t think to ask the question. For example, it appears that in 1997, the Galileo orbiter flew through a jet of water shooting out from Jupiter’s moon Europa without even trying.

Scientists think that Europa has an ocean below its icy surface, which could be a big deal. When we hear water, we think “life,” and maybe life found a way in Europa’s ocean. Recent Hubble space telescope images appeared to show evidence for this ocean in the form of plumes of water shooting forth from cracks in the moon’s surface ice. So, a team of researchers in the U.S. thought, maybe there’s more evidence for these plumes elsewhere, like in 20-year-old data from the Galileo orbiter.

“This wasn’t planned out,” study author Xianzhe Jia from the University of Michigan told Gizmodo. “It just so happened that the spacecraft passed through a region where we saw plumes. It was fortuitous.”

According to the current dominant theory, if there are other universes out there, they’re not likely to have life. But now an international team of researchers has demonstrated that the Multiverse is more hospitable than we thought.

The Multiverse hypothesis — wherein our observable Universe is just one of many universes — is a proposed explanation for the not-large-enough amount of dark energy in the empty space in our Universe.

We don’t really know what dark energy is — it’s the name we give to the force that drives the expansion of our Universe, which, contrary to pretty much everything else we observe, accelerates over time instead of slowing down.

A new critical story on #transhumanism out in the National Review:

Its promise of a kind of immortality is an ersatz version of Christian hope for a resurrection in a glorified body.
