Even though it's now possible to 3D-print foods into millimeter-precise shapes and forms, cooking those printed foods is still an inexact process. Scientists are trying to change that, by using lasers to cook foods to specific optimized standards.

In a busy workshop, it's possible to lose track of what substance a given sheet of material is composed of – making it risky to cut with a laser. SensiCut is designed to help, by identifying 30 different materials based on their surface qualities.

A compelling new study is offering an insight into the mechanism by which a novel form of light therapy can speed the healing of burn injuries. The research indicates the experimental therapy can activate a key protein that stimulates cell growth.

Physicists have outlined a relatively simple new way to create antimatter, by firing two lasers at each other to reproduce the conditions near a neutron star, converting light into matter and antimatter. Doing so could unlock cosmological mysteries.

Scientists at South Korea's Center for Relativistic Laser Science have achieved a major milestone in physics – and one pursued by researchers in the field for decades – by generating a record-breaking ultra-high intensity laser.

Scientists have developed a tiny first-of-its-kind imaging sensor designed to build detailed 3D maps of cellular structures inside the body, potentially revealing stiffness and abnormalities that may be indicative of cancer.

Startup Carbon Robotics has wheeled out an autonomous machine for farmers that has weeds in its cross hairs, using a combination of computer vision and high-powered lasers to comb fields and take out thousands of the pesky plants an hour.

Scientists at CERN have used lasers to cool down antimatter for the first time. The milestone could help unlock some of the secrets of this weird substance, including why it didn’t annihilate the universe soon after the Big Bang.

Heart attacks occur when plaque deposits break off of blood vessel walls, subsequently blocking arteries that carry oxygen to the heart. A new imaging process could identify those unstable deposits, allowing them to be treated before they rupture.

Judging how ripe fruit is can be frustrating for everyone from farmers to shoppers. Now researchers in Japan have developed a new way to check, without touching or damaging soft fruit like mangoes. All it takes is a laser and some plasma shockwaves.

When you're laser-cutting parts for a build project, you obviously want to be as efficient as possible. A new MIT-created program is designed to help, by optimizing the manner in which parts are cut from sheets of raw material.

A Stanford team has demonstrated a unique system that can generate a strong sonar wave, and read and interpret the reflected signals, from an airborne platform. This raises the possibility of sonar-enabled drones that could finally map the sea floor.
