A study finds that the brains of people who score higher in loneliness react in unique ways when viewing video content.

Startup Precision Neuroscience has tested its flexible, ultra-thin brain implants in people for the first time.

To make its weather predictions, it analyzes 60 million daily observations from satellite, aircraft, and ground-based reports, using what we know about atmospheric physics to determine what the weather is likely to be like across the globe over the next 15 days.

This can literally save lives — if people know in advance that hurricanes or winter storms are heading their way, they can take action to prepare — but because the model is so complex, it must be run on a supercomputer over the course of several hours, which also makes it expensive.

The AIs: AI-based weather forecasting models are starting to catch up with traditional ones, like the European Model.

MIT researchers find that extratropical storm tracks would change significantly with solar geoengineering efforts.

AI systems assume humans are always certain. Teaching them to anticipate and understand uncertainty may be key to limiting human error.

Imagine that a soldier has a tiny computer device injected into their bloodstream that can be guided with a magnet to specific regions of their brain. With training, the soldier could then control weapon systems thousands of miles away using their thoughts alone. Embedding a similar type of computer in a soldier’s brain could suppress their fear and anxiety, allowing them to carry out combat missions more efficiently. Going one step further, a device equipped with an artificial intelligence system could directly control a soldier’s behavior by predicting what options they would choose in their current situation.

While these examples may sound like science fiction, the science to develop neurotechnologies like these is already in development. Brain-computer interfaces, or BCI, are technologies that decode and transmit brain signals to an external device to carry out a desired action. Basically, a user would only need to think about what they want to do, and a computer would do it for them.

BCIs are currently being tested in people with severe neuromuscular disorders to help them recover everyday functions like communication and mobility. For example, patients can turn on a light switch by visualizing the action and having a BCI decode their brain signals and transmit it to the switch. Likewise, patients can focus on specific letters, words or phrases on a computer screen that a BCI can move a cursor to select.

A newly discovered brain cell that appears to be a hybrid of the two other primary types could shake up the world of neuroscience.

The challenge: There are very few ways to slow down Alzheimer’s disease or treat its symptoms, and there’s no cure — in 2021, nearly 120,000 Americans died from Alzheimer’s complications, making it one of the top 10 leading causes of death.

One genetic variant in particular — called APOE-e4 — is strongly tied to the brain disease. Having one copy makes a person 2–3 times more likely to develop Alzheimer’s, while having two copies (one from each parent) increases the risk by 8–12 times.

Columbia University researchers have identified patterns of brain injury linked to “hidden consciousness” — and the discovery could lead to better outcomes for people in comas or vegetative states.

Hidden consciousness: Severe brain injuries can cause “disorders of consciousness” (DoC), such as vegetative states, in which a person looks awake, but lacks any indication they are aware of their surroundings, and comas, where they appear neither awake nor aware.

An estimated 15–20% of people with a DoC are also experiencing a phenomenon called “cognitive motor dissociation” (CMD), or “hidden consciousness.” That means they are aware of what’s going on around them, but they can’t physically respond to it.
