Microbes in the gut can help the immune system fight cancer, and a fiber-rich diet may be key to reaping the benefits, a study in mice suggests.The immune system plays an important role in the body’s fight against cancer. At the forefront of this resistance are CD8+ killer T cells, a type of immune cell that surrounds tumors and kills cancer cells. However, as each battle continues, these cells become exhausted and are no longer able to find tumors effectively. So there is a need for treatments that give cells enough oomph to finish their job.Now, in a study published…
Google is rolling out new AI-powered features for booking and planning travel in search, the company announced on Monday. The tech giant is expanding the availability of its AI-powered “Flight Deals” tool, adding the ability for users to organize their travel plans with the AI-mode “Canvas” tool, and bringing agent booking capabilities to more people. Google launched its first flight sale in the US, Canada, and India in August. Now, the company is expanding its AI-powered search tools within Google Flights around the world to help people quickly find affordable destinations. First, users must describe where, when, and how they…
November 17, 2025Ravi Lakshmanan Cybersecurity researchers discovered a malware campaign deploying Amatera Stealer and NetSupport RATs using the now popular ClickFix social engineering tactic. This activity observed this month is tracked by eSentire under the name EVALUSION. First discovered in June 2025, Amatera is believed to be an evolution of ACR (short for “AcridRain”) Stealer, which was available in a malware-as-a-service (MaaS) model until malware sales ceased in mid-July 2024. Amatera is available through subscription plans ranging from $199 per month to $1,499 per year. “Amatera provides threat actors with extensive data exfiltration capabilities across crypto wallets, browsers, messaging applications,…
Invading parasitic ant queens trick workers in various colonies into killing and dismembering their own mothers, allowing the invaders to intervene and usurp the throne, according to a new study.The parasite appears to invade the colony and spray the reigning queen with formic acid.”The queen’s odor is erased by formic acid, instantly turning her most urgent protection into a deadly threat. This is nothing short of a nightmare for the host queen and the workers alike,” study lead author Keizo Takasuka, a biologist at Kyushu University in Japan, told LiveScience in an email. you may like Some species of ants,…
If you pay attention to what major technology companies are saying about the demand for AI, you’ll notice a common thread: a lack of computing power. This means that the large language models that power today’s AI products require more data centers for training and inference, and therefore more power. Against this backdrop, energy efficiency has suddenly become a key priority for semiconductor manufacturers. PowerLattice, a startup founded in 2023 by veteran electrical engineers from Qualcomm, NUVIA, and Intel, claims to have developed a breakthrough approach that reduces the power demand of computer chips by more than 50%. On Monday,…
Researchers have found that the Gulf of Suez, which partially separates Africa and Asia, may still be expanding.Starting about 28 million years ago, the Arabian Plate separated from the African Plate, opening up what is today the Gulf of Suez. This type of rift would lead to the birth of a new ocean, but about 5 million years ago the rift stopped, leaving Suez a bay rather than an ocean.Anyway, that’s the conventional story. But the Suez Rift rift never stopped cracking, according to a new study. Instead, it just slowed down. A new paper published Nov. 3 in the…
Three years ago, Luminal co-founder Joe Fioti was working on chip design at Intel. He was working on making the best chip possible, but the more important bottleneck was in the software. “You can make the best hardware on the planet, but if it’s difficult for developers to use, they won’t use it,” he told me. Now he has founded a company focused entirely on that problem. On Monday, Luminal announced $5.3 million in seed funding in a round led by Felicis Ventures with angel investments from Paul Graham, Guillermo Rauch, and Ben Porterfield. Fioti co-founders Jake Stevens and Matthew…
Refresh 2025-11-20T15:35:32.832Z Science and the AI bubble (Image credit: Shutterstock) Live Science is hardly the first site you visit for stock market tips, but it’s difficult to go anywhere these days without hearing loose talk about a potential AI bubble.For the time being, market jitters over an imminent pop appear to have been shrugged off by Nvidia’s strong quarterly results, the Financial Times reports.But what happens to science if ballooning investment into Large Language Models goes bust? The knock-on effects for funding and jobs could be bad, but not without their silver linings, this Nature article outlines. 2025-11-20T15:15:56.280Z Viking Age…
Refresh 2025-11-21T15:08:15.686Z Impossible void-trapped galaxy is still churning out stars (Image credit: Sloan Digital Sky Survey) In a spectacular cosmoc example of making proverbial lemonade, scientists have observed a void trapped galaxy that still seems to be readily churning out stars, Live Science contributor Joanna Thompson writes.The dwarf galaxy NGC 6789 is located approximately 12 million light-years from Earth in an empty region known as the Local Void, and yet despite a dearth of surrounding material, it still seems able to readily produce stars.Scientists expect future observations to reveal why. But until then, the galaxy’s star making ability remains a…

There are stromatolites, or microbial mats, found in Australia that date to 3.48 billion years ago. Other traces of ancient life have been more controversial: In 2017, scientists argued that chemical traces in 3.95-billion-year-old rocks from Labrador, Canada may constitute Earth’s earliest evidence of life.But…
