The headline is pretty uninformative.

Basically, they found a signature in the interactions of certain areas of the brain that correlated with a reduced ability to carry out this behavior called joint attention. They think measuring this signature could be a means for detecting autism earlier in development, opening the possibility for helping the brain develop more correctly early on in autistic patients' brains.

Is it surprising though. It's profoundly heartbreaking the suffering these doctors witness. A person who was once full now has withered away. Even in your best efforts.

Oncologists spend sometime with these patients. Not every happy ending, ends the doctors bad memories. I wish we took better care of our doctors mental health.

Researchers discover faster, more efficient gait for six-legged robots walking on flat ground. Bio-inspired gaits used by real insects are less efficient for robots. Results provide novel approaches for roboticists and new information to biologists.

In the video it describes that when you take insects' ability to adhere to surfaces away, via tiny adorable boots, they change their gait to one closer to the one the robot uses. So, the reason for the less fast gait has to do with needing to also stick to things - something ground-based spiderbots don't need.

I just want to point out that these Vitamins (B6, B8, and B12) were used as a supplemental drug (an adjunctive) to antipsychotics. It wasn't just vitamins and minerals on their own. Not trying to prove a point, but I think it's an important distinction the title leaves out.

When people hear "organic," they think "life." But with chemistry, that's not necessarily so. Although organic sounds a whole lot like organism, in the parlance of chemists the word basically only means 'stuff with carbon atoms in it'.

Record scratch. Very cool nonetheless.

Hi Reddit! I am Chris Borstad, Associate Professor of Snow and Ice Physics at the University Centre in Svalbard (UNIS). Located at 78 degrees north, UNIS (www.unis.no) is the northernmost institution of higher education and research in the world. I am fascinated by snow and ice, and my research relates to processes that cause ice and snow to fracture. Most recently I have been studying the Larsen C ice shelf in Antarctica, where a massive crack in the ice is about to release an iceberg the size of Delaware! By improving our understanding of what caused this event and what the consequences are for the ice shelf, we hope to make better predictions of how other ice shelves around Antarctica will respond to a changing climate. I also study the physics of snow avalanches, a research interest that originated with a desire not to get caught in an avalanche myself while skiing in the backcountry. The most destructive types of avalanches occur after a large volume of snow is undercut by fractures. I am working to better understand these fascinating natural phenomena so that we can hopefully keep people out of harm’s way.

I will be back to answer your questions at 12 pm ET, Ask me Anything!

What can be done (if anything) to prevent the Larsen C ice shelf in Antarctica from cracking and releasing the iceberg? What are the consequences of this being released?
