Scientists have built the first all-optical photonic time crystal, allowing them to reshape the behavior of terahertz light at extraordinary speeds。 The breakthrough could open the door to ultrafast computing, smarter communication systems, advanced imaging, and a new generation of highly tunable lasers
It marks a change of tone for his administration, which has taken a more hands-off approach to the technology
The regulator said a fee of between £237,500 to £712,500 per megawatt should be charged for upcoming projects
Thawing Arctic permafrost is releasing ancient carbon into the ocean, raising fears that microbes could turn it into greenhouse gases and accelerate climate change。 But sediment cores collected near Canada’s Herschel Island reveal a more reassuring twist: most of this land-based carbon becomes buried in the seafloor, while only about 10 percent is
A Louisiana launch site would offer several significant advantages
Vanderbilt researchers created the first selective compound designed to inhibit TAOK-1, a poorly understood protein connected to Alzheimer’s disease。 They also discovered a second compound that activates the entire TAOK protein family, offering scientists an unexpected new research tool。 Together, the compounds could reveal hidden disease mechanism
Dark matter particles may exert a hidden force on one another, but its effects are stranger than expected。 An extra attraction helps the particles cluster, yet it also makes dark matter effectively lighter as the Universe expands。 That weakens its gravitational impact and usually slows the growth of cosmic structure rather than accelerating it
The country’s iconic carmakers are struggling with tariffs, the growth of electric vehicles and intense competition from Chinese companies
Tracking smells in turbulent air takes a keen sense of direction and sharp memory
Once united in support of President Trump, right-wing influencers are embroiled in feuds and losing viewers, creating a problem for Republicans in the midterm elections
Save on We-Vibe, including app-controlled bestsellers and popular gift sets designed for couples, connection, and shared pleasure
Clement Delangue said he didn't want cyber attacks on other companies to become "normalised"
Fenix Flexin’s hit song “Rubberz” has hip-hop fans arguing over whether it was generated by AI。 Some say they have proof it’s machine-made, but will anyone care
Inside the 81-year-old billionaire’s risky, debt-fueled scramble to transform his data empire into an A。 juggernaut
Smart mowers are an expensive alternative to old-fashioned yard work, but they’re finally good enough to consider if you’d rather sip an iced tea and watch a robot tame your lawn
Reddit may still be considering ending its licensing deal with Google

When atomic nuclei smash together at nearly the speed of light, they create the hottest fluid in the universe, but scientists may have overlooked one of its most important forces。 New simulations reveal that extreme acceleration builds up along the edges of quark-gluon plasma, helping drive its explosive expansion。 This acceleration may do far more
