LIGO Surpasses the Quantum Limit
In 2015, the Laser Interferometer Gravitational-Wave Observatory, or LIGO, made history when it made the first direct detection of gravitational waves, or ripples in space and time, produced by a pair of colliding black holes. Since then, the U.S. National Science Foundation (NSF)-funded LIGO and its sister detector in Europe, Virgo, have detected gravitational waves from dozens of mergers between black holes as well as from collisions between a related class of stellar remnants called neutron stars.

Wobbly gel mat trains muscle cells to work together
The vibrating platform could be useful for growing artificial muscles to power soft robots and testing therapies for neuromuscular diseases. There's no doubt that exercise does a body good, including strengthening and toning our muscles. But how exactly does exercise make this happen? As we run and lift and stretch, our muscles experience chemical signals from surrounding cells, as well as mechanical forces from jostling against tissues.

Black holes could come in ’perfect pairs’ in an ever expanding Universe
Researchers from the University of Southampton, together with colleagues from the universities of Cambridge and Barcelona, have shown it's theoretically possible for black holes to exist in perfectly balanced pairs - held in equilibrium by a cosmological force - mimicking a single black hole. Black holes are massive astronomical objects that have such a strong gravitational pull that nothing, not even light, can escape.

Chemists present method for the fluorination of enines
Research team from the University of Münster presents synthesis method in Nature Chemistry Fluorinated small molecules are very often used to produce medicines or agrochemicals. However, they rarely occur naturally. The societal importance of fluorinated substances, combined with the lack of natural sources, has created a demand for effective, sustainable methods to generate new fluorinated motifs - molecular structures containing one or more fluorine atom - from relatively simple starting materials.

Superlensing without a superlens: microscopes boosted beyond limits
Physicists at the University of Sydney have shown a new pathway to achieve superlensing with minimal losses, breaking through the diffraction limit by a factor of nearly four times. Their trick? Remove the superlens altogether. Ever since Antonie van Leeuwenhoek discovered the world of bacteria through a microscope in the late seventeenth century, humans have tried to look deeper into the world of the infinitesimally small.

From a five-layer graphene sandwich, a rare electronic state emerges
A newly discovered type of electronic behavior could help with packing more data into magnetic memory devices. Ordinary pencil lead holds extraordinary properties when shaved down to layers as thin as an atom. A single, atom-thin sheet of graphite, known as graphene, is just a tiny fraction of the width of a human hair.

New technique helps robots pack objects into a tight space
New technique helps robots pack objects into a tight space
Researchers coaxed a family of generative AI models to work together to solve multistep robot manipulation problems. Anyone who has ever tried to pack a family-sized amount of luggage into a sedan-sized trunk knows this is a hard problem. Robots struggle with dense packing tasks, too. For the robot, solving the packing problem involves satisfying many constraints, such as stacking luggage so suitcases don't topple out of the trunk, heavy objects aren't placed on top of lighter ones, and collisions between the robotic arm and the car's bumper are avoided.
