You don't necessarily have to travel for it, but I agree that most prejudices are born out lack of information. If you actually get to know the people you fill that void with reality.

This is potentially a huge deal if it works out: the energy density of batteries (in mAh per either gram or cubic centimeter) has been nearly stalled out for years, with increases of a few percent being a big deal, and that's the major limitation in portable electronic devices today. Their related tendency to explode if things go wrong is a major safety headache. For higher-drain applications like cars or building power backups, these problems are only more serious.

Goodenough and Braga's invention, if it becomes productionizable, is therefore a huge deal: a 3x increase in energy density, without the risk of explosion, fast rates of charge and discharge, a long cycle life, capable of operating down to -20C, and made from less expensive materials than today's lithium-ion batteries.

And this isn't the usual "fringe researcher claims to have solved problem that nobody else could!" which the press occasionally gets excited about (and which never pans out); Goodenough is co-inventor of the very lithium-ion batteries which this replaces, and he and Braga are two very well-respected experts in the field. They're precisely the sort of people who would be best-placed to come up with something, and to validate an idea if it were out there.

In fact, it's good enough that my main question is "what's the catch?" – because new technologies which are strictly better than the old ones along literally every single axis are pretty rare. If this is the real deal, then it's fantastic news all around, and huge kudos to both of them for an invention that could really improve the world!

PSA Group is using Sentiance technology to personalize the in-car experience. Their new autonomous and connected concept car, PEUGEOT INSTINCT CONCEPT, leverages the contextual capabilities of the Sentiance platform to personalize the end-to-end car experience by tailoring presets and recommendations based on driver profiles and real-time context.

A Belgian discovers some planets, calls them trappist. That really lights up my day :D.

People living on those planets would be called trappists!
Need a recap of today’s TRAPPIST-1 announcement? Learn about these seven Earth-sized planets orbiting a single star here: http://nasa.tumblr.com/post/157579604399/largest-batch-of-earth-size-habitable-zone

This news definitely beats the previous article!
It's really nice to be able to share good news for once. A new study in JAMA Pediatrics studied the effect of same-sex marriage laws on teen suicide rates. They looked at 32 different US states which changed their laws at different times, as a way of disentangling this effect from other effects.

The net result? Legalizing same-sex marriage leads to a 7% overall drop in teen suicide attempts, and a 14% drop among LGBT teens.

It turns out that being publicly told that you're an accepted member of society and not a pariah does make a difference in people's lives, especially teenagers. Who woulda thunk?

But the upshot of this is: All of you who worked on this, in one way or another? You just saved some lives. Well done.

The article itself is available online: http://jamanetwork.com/journals/jamapediatrics/fullarticle/2604258

(NB: For clarity, that's a 7% drop in the rate, not a seven percentage point drop drop. We should be so lucky as to have any one thing eliminate seven percentage points. As a baseline, a weighted 8.6% of all high school students, and 28.5% of LGBT high school students, attempted suicide in the year before same-sex marriage legalization. Suicide is the second most common cause of death among people aged 15-24 in the US.

For those who want technical notes: The paper seems to have done a very careful job on statistics, testing a wide variety of alternate hypotheses and ruling them out from the data. One test worth calling out: the two-year leading indicator (suicide rates two years prior to law changes) was not correlated to suicide rates, indicating that this was not triggered by general changes in the state which were also leading to this; the two-year trailing indicator (two years after), however, was correlated, with the same correlation as the immediate future, indicating a lasting effect rather than a one-off.)
