Scientists have built detailed Milky Way simulations under strange new physical laws to probe dark matter, revealing how different versions of the universe might behave and helping us get closer to the real one.

Physicists at the University of Colorado Boulder have created a groundbreaking quantum device that can measure 3D acceleration using ultracold atoms, something once thought nearly impossible. By chilling rubidium atoms to near absolute zero and splitting them into quantum superpositions, the team has built a compact atom interferometer guided by AI to decode acceleration patterns. While the sensor still lags behind traditional GPS and accelerometers, it's poised to revolutionize navigation for vehicles like submarines or spacecraft potentially offering a timeless, atomic-based alternative to aging electronics.

Scientists at the University of Michigan have unlocked a long-standing mystery about quasicrystals exotic materials that straddle the line between the orderly structure of crystals and the chaos of glass. These rare solids, which once seemed to break the rules of physics, are now shown to be fundamentally stable through cutting-edge quantum simulations. The findings not only validate their existence but also open the door to designing next-generation materials using powerful new computational techniques.

Scientists have uncovered a previously unknown type of molecular motion inside DNA-based droplets: instead of spreading randomly, guest molecules advance in an organized wave. This surprising discovery opens the door to understanding how cells might organize internal processes without membranes. Using customizable DNA condensates as experimental models, the team showed how molecular waves emerge through precise DNA interactions. These insights could not only transform our grasp of cellular signaling but may even lay groundwork for treating neurodegenerative diseases by influencing how molecules behave inside aging cells.

California s solar energy boom is often hailed as a green success story but a new study reveals a murkier reality beneath the sunlit panels. Researchers uncover seven distinct forms of corruption threatening the integrity of the state s clean energy expansion, including favoritism, land grabs, and misleading environmental claims. Perhaps most eyebrow-raising are allegations of romantic entanglements between senior officials and solar lobbyists, blurring the lines between personal influence and public interest. The report paints a picture of a solar sector racing ahead while governance and ethical safeguards fall dangerously behind.

Physicists have managed to simulate a strange quantum phenomenon where light appears to arise from empty space a concept that until now has only existed in theory. Using cutting-edge simulations, researchers modeled how powerful lasers interact with the so-called quantum vacuum, revealing how photons could bounce off each other and even generate new beams of light. These breakthroughs come just as new ultra-powerful laser facilities are preparing to test these mind-bending effects in reality, potentially opening a gateway to uncovering new physics and even dark matter particles.

Scientists at Binghamton University are bringing a sci-fi fantasy to life by developing tiny batteries that vanish after use inspired by Mission: Impossible. Led by Professor Seokheun Choi, the team is tackling one of the trickiest parts of biodegradable electronics: the power source. Instead of using toxic materials, they re exploring probiotics friendly bacteria often found in yogurt to generate electricity. With engineered paper-based batteries that dissolve in acidic environments, this breakthrough could revolutionize safe, disposable tech for medical and environmental use.

Harvard and PSI scientists have managed to freeze normally fleeting quantum states in time, creating a pathway to control them using pure electronic tricks and laser precision.

New research demonstrates that with collaboration between stakeholders, Australia can fully decarbonize its domestic and energy export economies by 2060 -- a feat requiring $6.2 trillion USD and around 110,000 square kilomters of land -- while avoiding harm to important areas for biodiversity outcomes, safeguarding agricultural activities, and respecting Indigenous land rights.

A new study found exposure to specific tiny particles in air pollution during pregnancy are associated with increased risk of various negative birth outcomes.

A new study details processes that keep pollutants aloft despite a drop in emissions.

A new type of mRNA vaccine is more scalable and adaptable to continuously evolving viruses such as SARS-CoV-2 and H5N1, according to a new study.

Electronics often get thrown away after use because recycling them requires extensive work for little payoff. Researchers have now found a way to change the game.

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light.

Despite advances in machine vision, processing visual data requires substantial computing resources and energy, limiting deployment in edge devices. Now, researchers from Japan have developed a self-powered artificial synapse that distinguishes colors with high resolution across the visible spectrum, approaching human eye capabilities. The device, which integrates dye-sensitized solar cells, generates its electricity and can perform complex logic operations without additional circuitry, paving the way for capable computer vision systems integrated in everyday devices.

Researchers have synthesized a new compound called infuzide that shows activity against resistant strains of pathogens.

Researchers have recreated the world's oldest synthetic pigment, called Egyptian blue, which was used in ancient Egypt about 5,000 years ago.

Researchers have discovered that the mixing of small particles between two solid electrolytes can generate an effect called a 'space charge layer,' an accumulation of electric charge at the interface between the two materials. The finding could aid the development of batteries with solid electrolytes, called solid-state batteries, for applications including mobile devices and electric vehicles.

Researchers have engineered a laser device smaller than a penny that they say could power everything from the LiDAR systems used in self-driving vehicles to gravitational wave detection, one of the most delicate experiments in existence to observe and understand our universe.

Scientists have reported use of antibacterial coatings made from resilin-mimetic proteins to fully block bacteria from attaching to a surface. A protein that gives fleas their bounce has been used to boot out bacteria cells, with lab results demonstrating the material's potential for preventing medical implant infection.
