Scientists at the Marine Biological Laboratory in Woods Hole, Massachusetts, and their colleagues reported on Monday in the journal Nucleic Acids Research that longfin inshore squid (Doryteuthis pealeii) are the first known animals that can edit messenger RNA outside the cell nucleus.
Companies like Twitter and Square—which share Jack Dorsey as CEO—have now taken the next logical step of asking employees to work from home whenever possible, and more could potentially follow their lead.
Janelia researchers announced a major step in that quest on Wednesday, releasing a wiring diagram of the fly brain that contains 25,000 neurons and the 20 million connections between them.Rubin hopes wiring diagrams such as this one, showing neurons involved in navigation, will give researchers a better sense of how brain circuits work.
Anadol creates mesmerizing art installations by seeking out interesting data sets and processing them into swirling visualizations of how computers capture the world and people in it.Anadol used machine learning to group photos and morph between them, creating flickering images of the city as recorded by many different people.
The other was a tax credit that allowed businesses and individuals to deduct 30 percent of the cost of installing new solar panels from their taxes.After that, individuals won’t receive any tax credits for installing solar on their homes, and business owners will receive a paltry 10 percent.
If you could press a button to merge your mind with an artificial intelligence computer—expanding your brain power, your memory, and your creative capacity—would you take the leap?“I would press it in a microsecond,” says Sebastian Thrun, who previously led Stanford University’s AI Lab. Turning yourself into a cyborg might sound like pure sci-fi, but recent progress in AI, neural implants , and wearable gadgets make it seem increasingly imaginable.
The tumor, which she nicknamed Brian, was remarkable chiefly because of its size: 4.6 centimeters across.“Plot twist,” Giertz says in a subdued voice during a YouTube dispatch about the golf-ball-sized growth at the time.Even before the brain tumor, Giertz says, she was starting to feel like “it was harder and harder to come up with ideas.
“Sleep is like the dishwasher of the brain,” Prather explains in WIRED’s latest “Five Levels ” video.But Prather says all phases, from the lightest slumber to the deepest unconsciousness, are important processes that allow our brains and bodies to recover from the previous day and can help us learn and remember information better.
Brains are cleaning and planes are intervening, but first: a deadly Halloween cartoon .Here's the news you need to know, in two minutes or less.Scientists now know how sleep cleans toxins from the brain.
Lewis outfitted the participants with an EEG cap so she could look at the electrical currents flowing through their brains.“It’s a fantastic paper,” says Maiken Nedergaard, a neuroscientist at the University of Rochester who led the 2013 study that first described how sleep can clear out toxins in mice.
So it’s not surprising that the NFL's helmet testing and ranking has had no discernable impact on the incidence of concussions (to say nothing of the incidence of clinically silent injury, which hasn’t been measured at all).
The startup it purchased is CTRL-Labs (pronounced “Control” labs), a four-year-old company that uses a mix of machine learning and neuroscience to allow people to manipulate computer interfaces simply by brainpower.“It captures your intention so you can share a photo with a friend using an imperceptible movement or just by, well, intending to,” says Facebook’s VP of AR/VR Andrew Bosworth in a statement about the company’s new toy.
Around a decade ago, Seattle-based 3D animation artist Cody Cobb began taking long solo camping trips through the American West, bringing along a camera and shooting what he saw.
Young, Shapley, and Chariker’s work accepts the demanding, unintuitive biology of the visual cortex as is—and tries to explain how the phenomenon of vision is still possible.“I think their model is an improvement in that it’s really founded on the real brain anatomy.

If Neuralink’s technologies work as Musk and his team intend, they’ll be able to pick up signals from across a person’s brain—first from the motor cortex that controls movement but eventually throughout your think-meat—and turn them into machine-readable code that a computer can understand.
Over the first half of the BRAIN initiative, scientists and engineers have developed technologies to discover and catalog the unique electrical properties of brain cells and to begin to reveal how they work together to generate sensations and movements.
Though the experiments were conducted in mice, and are just a proof of concept, Ramirez says understanding how these regions of the brain play a role in enhancing positive memories or suppressing negative ones could unlock targets for treating psychiatric disorders like depression, anxiety, and PTSD.Scientists identified neurons in a mouse's hippocampus, shown in green, that were involved in encoding a fear memory.
Everybody says, “This is a smart idea, but we're not actually going to be able to design computers this way.” Explain why you persisted and why you were so confident that you had found something important. And on small data sets, other methods, like things called support vector machines worked a little bit better.
Taryn Southern, the co-director of the film, says she began thinking about the brain just as shows like Black Mirror and Westworld , which play on the relationship between humans and technology, began their ascendency.
If a person has one in their head, while they talk, Chang’s team can take readings from their motor cortex—recording the activity corresponding to speech or, more specifically, the movement of the mouth, the tongue, and the jaw.
After Walker’s talk, he was mobbed by acolytes in the conference center desperate to tell him how much his book—which covers the same topic as his TED talk—changed their lives, how they’d given up caffeine and alcohol and stopped feeling bad for leaving parties early to get sleep or refusing to look at work emails in bed.
And mice don’t have anywhere near our behavioral complexity.“It's important to recognize here the mouse doesn't really have depression per se,” says Yale psychiatrist Alex Kwan, who has studied the effects of ketamine on mouse brains.
More than a century ago, the psychologist Walter Pillsbury wrote: “There is nothing in the mind that has not been explained in terms of movement.” This concept has its modern incarnation in the mirror neuron theory, which posits that the ability to glean meaning from gesture and speech can be explained by the activation of single cells in key brain regions.
