When the disembodied cockroach leg twitched, Yeongin Kim knew he had finally made it.
A graduate student at Stanford, Kim had been working with an international team of neuroengineers on a crazy project: an artificial nerve that acts like the real thing. Like sensory neurons embedded in our skin, the device—which kind of looks like a bendy Band-Aid—detects touch, processes the information, and sends it off to other nerves.
Yup, even if that downstream nerve is inside a cockroach leg.
Very promising since “Identifying what changes are happening in the brain when interventions successfully reduce depressive symptoms could allow us to create more effective, pharmaceutical-free approaches to help alleviate depression in people who experience chronic traumatic brain injury symptoms,” said study author Dr. Sandra Bond Chapman, founder and chief director of the Center for BrainHealth.

Nothing goes out of date more quickly than films set in the future. Big-screen visions of tomorrow always reflect the era in which they were made – hence the disco outfits in Flash Gordon. Most soon become quaint relics rather than uncanny prophecies of the shape of things to come. But then, on the other hand, there is Children of Men. Alfonso Cuarón’s feverish dystopian chase thriller is set in a decade’s time, in 2027, but it also came out a decade ago. By now, we should be chuckling at how far off-target its predictions were, both in their overall picture and their background minutiae. Instead, it’s tempting to ask whether Cuarón had access to a crystal ball.
Alfonso Cuarón’s dystopian thriller is one of the 21st Century’s most acclaimed films – and its version of the future is now disturbingly familiar. Nicholas Barber looks back.

Microsoft is leveraging technology from submarines and working with pioneers in marine energy for the second phase of its moonshot to develop self-sufficient underwater datacenters that can deliver lightning-quick cloud services to coastal cities. An experimental, shipping-container-size prototype is processing workloads on the seafloor near Scotland’s Orkney Islands, Microsoft announced today.
The deployment of the Northern Isles datacenter at the European Marine Energy Centre marks a milestone in Microsoft’s Project Natick, a years-long research effort to investigate manufacturing and operating environmentally sustainable, prepackaged datacenter units that can be ordered to size, rapidly deployed and left to operate lights out on the seafloor for years.
“That is kind of a crazy set of demands to make,” said Peter Lee, corporate vice president of Microsoft AI and Research, who leads the New Experiences and Technologies, or NExT, group. “Natick is trying to get there.”
The Higgs boson appeared again at the world’s largest atom smasher — this time, alongside a top quark and an antitop quark, the heaviest known fundamental particles. And this new discovery could help scientists better understand why fundamental particles have the mass they do.
When scientists at the Large Hadron Collider (LHC) first confirmed the Higgs’ existence back in 2013, it was a big deal. As Live Science reported at the time, the discovery filled in the last missing piece of the Standard Model of physics, which explains the behavior of tiny subatomic particles. It also confirmed physicists’ basic assumptions about how the universe works. But simply finding the Higgs didn’t answer every question scientists have about how the Higgs behaves. This new observation starts to fill in the gaps.
As the European Organization for Nuclear Research (CERN), the scientific organization that operates the LHC, explained in a statement, one of the most significant mysteries in particle physics is the major mass differences between fermions, the particles that make up matter. An electron, for example, is a bit less than one three-millionth the mass of a top quark. Researchers believe that the Higgs boson, with its role (as Live Science previously explained) in giving rise to mass in the universe, could be the key to that mystery.

MIT researchers, working with scientists from Brigham and Women’s Hospital, have developed a new way to power and communicate with devices implanted deep within the human body. Such devices could be used to deliver drugs, monitor conditions inside the body, or treat disease by stimulating the brain with electricity or light.
The implants are powered by radio frequency waves, which can safely pass through human tissues. In tests in animals, the researchers showed that the waves can power devices located 10 centimeters deep in tissue, from a distance of 1 meter.
“Even though these tiny implantable devices have no batteries, we can now communicate with them from a distance outside the body. This opens up entirely new types of medical applications,” says Fadel Adib, an assistant professor in MIT’s Media Lab and a senior author of the paper, which will be presented at the Association for Computing Machinery Special Interest Group on Data Communication (SIGCOMM) conference in August.
