Scientists have identified a molecular switch that may help explain why aging makes the brain more vulnerable to diseases such as ALS and Huntington’s。 In worms, the protein EPS8 builds up with age and triggers signaling that encourages toxic proteins to clump together, damaging neurons and shortening lifespan。 Reducing EPS8 activity prevented thes
Amazon joined a procession of tech giants that ramped up their spending on artificial intelligence, as its capital expenditures soared 69 percent。 Concerns over the industry’s spending are mounting
The solar wind may be stripping away Mars’ atmosphere by creating giant rolling waves along its outer edge。 Data from MAVEN and Tianwen-1 show that these waves form plasma clouds that carry atmospheric particles into space。 The process is concentrated on one side of Mars and may have played a major role in drying out the once potentially habitable
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
Coastal communities are facing a hidden threat that is making rising seas far more dangerous: the land beneath them is sinking。 New research shows that people in densely populated coastal regions experience an average relative sea-level rise of about 6 millimeters per year, nearly three times the global coastal average。 Groundwater pumping, oil and
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
Scientists have figured out how two famously poisonous plants create chemicals with surprising medical potential。 After tracking thousands of genes in wolfsbane and larkspur, they identified six enzymes needed to build a complex compound called atisinium。 The team recreated the process inside tobacco plants, offering a sustainable way to produce an
Ultrafast X-rays revealed how a molecule converts absorbed light into motion in just trillionths of a second。 Individual atoms recorded different stages of the process, opening a powerful new window into light-driven chemistry
As fears spread over a possible artificial intelligence bubble, some tech investors say: Bring it on
The disclosure followed OpenAI’s report last week that its own artificial intelligence had hacked into the network of an online library
A new field of “tokenomics” has emerged to measure the return on all the money companies are pouring into artificial intelligence
Internal documents show ICE's DNA collection has skyrocketed in the second Trump administration。 Now hundreds of thousands of people never convicted of a crime are in an FBI criminal database forever
Hi HN, we’re Bence and Ryan, founders of Hoplite (https://hoplite。 Hoplite lets you deploy coding agents in the cloud, with a suite of tools that makes it incredibly easy to QA features。 During onboarding, we port over your local setup - sessions, memories, MCP servers, and get your projects ready to run in the cloud
You can now buy panels that plug into electrical outlets, but there are some important safety issues to consider when picking and installing a system
A new chemical process can transform three of the most common plastics into high-purity hydrogen without sorting them first。 The technique operates at much lower temperatures than traditional gasification and captures most of the plastic’s carbon in solid or liquid forms instead of releasing it as carbon dioxide
New EU rules stipulate that people must be told when they’re interacting with AI or looking at AI-generated or -edited content, leading to fear of “disclosure fatigue
Low arginine levels may allow cancer cells and viruses to slip past the immune system by reducing production of a crucial cellular warning protein。 In mice, arginine-rich diets led to fewer colon tumors and milder viral infections, suggesting a simple supplement could have powerful therapeutic potential
The term "Milwaukee Shoulder Syndrome" was coined in 1981, based on cases in four women
The company recently raised prices on a number of products because of component supply shortages caused by the artificial intelligence boom
Physicists have uncovered a surprising limit to electrical resistance caused by particles colliding。 Using ultracold potassium atoms trapped in a grid of light, researchers created a highly controlled stand-in for electrons moving through a solid。 As collisions became more frequent and intense, resistance initially rose, but eventually hit a ceilin
