The AI that could help make limitless fusion power a reality: Supercomputer set to try and work out how to harness the energy of the sun

An AI is set to try and work out how a potentially limitless supply of energy can be used on Earth.

It could finally solve the mysteries of fusion power, letting researchers capture and control the process that powers the sun and stars.

Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University hope to harness a massive new supercomputer to work out how the doughnut-shaped devices, known as tokamaks, can be used.

Expert meet at new UN-hosted talks about ‘killer robots’

GENEVA (AP) — Experts from scores of countries are meeting to discuss ways to define and deal with “killer robots” — futuristic weapons systems that could conduct war without human intervention.

The weeklong gathering is the second this year at U.N. offices in Geneva to focus on such lethal autonomous weapons systems and explore ways of possibly regulating them, among other issues.

Some top advocacy groups say governments and militaries should be prevented from developing such systems, which have sparked fears and led some critics to envisage harrowing scenarios about their use.

Spear-toting robot can guard coral reefs against invasive lionfish

Lionfish are threats to not only fragile coral reef ecosystems, but the divers who keep them in check. They not only take advantage of unsuspecting fish populations, but carry poisonous spines that make them challenging to catch. Student researchers at Worcester Polytechnic Institute may have a solution: robotic guardians. They’ve crafted an autonomous robot (below) that can hunt lionfish without requiring a tethered operator that could harm the reefs.

The bot attaches to an existing submersible robot and relies on computer vision (trained with thousands of photos) to spot examples of the invasive species and jab them with one of its eight spears. Each spear tip is detachable and buoyant, so any successful kill sends the fish to the surface. The machine is well-suited to the realities of the ocean, too — it’s both resistant to saltwater corrosion and uses an airtight chamber to maintain buoyancy after every spear use.

WPI’s automaton isn’t ready for service yet. A follow-up group of students will work on a navigation system that can help the robot create a 3D search grid. If that’s successful, though, the robot could become a valuable part of reef defense that spares humans from getting involved until (and unless) they have no other choice.

Artificial Intelligence Is Now a Pentagon Priority. Will Silicon Valley Help?

Nonetheless, the Pentagon appears to be pushing ahead on its own, looking for ways to strengthen its ties with A.I. researchers, particularly in Silicon Valley, where there is considerable wariness about working with the military and intelligence agencies.

The Defense Department, believing that A.I. research should be a national priority, has called on the White House to “inspire a whole of country effort.”

AI is helping find lead pipes in Flint, Michigan

The algorithm is saving about $10 million as part of an effort to replace the city’s water infrastructure.

To catch you up: In 2014, Flint began getting water from Flint River rather than the Detroit water system. Mistreatment of the new water supply, combined with old lead pipes, created contaminated water for residents.

Solving the problem: Records that could be used to figure out which houses might be affected by corroded old pipes were missing or incomplete. So the city turned to AI. Using 71 different pieces of information—like the age or value of the home—Georgia Tech researchers developed an algorithm that predicted whether or not a home was connected to lead pipes.
