A clinical trial is exploring whether high doses of vitamin B3 could give patients with glioblastoma a better chance against the aggressive brain cancer. Scientists found that niacin may help revive immune cells that tumors shut down, allowing them to attack cancer more effectively. Early results have been promising, with patients showing significantly better progression-free survival than expected.

There are certain themes that movies in China can’t have, and one of them is time travel. In this clip we discuss China’s ban on time travel, how the CCP got Tesla and Elon Musk to heel, and why the CCP no longer needs Hollywood. Our guest is Chris Fenton, the producer of Bad Counselors, which comes to theaters July 22–27, 2026. https://www.badcounselors.com
Two cups of warm water don’t make one cup of boiling water. But in the quantum world, multiple low-energy photons can combine to produce a single, higher-energy photon.
A research team at Kyushu University has developed a solid-state molecular material that “upgrades” visible light into ultraviolet (UV) light under ordinary outdoor sunlight, achieving a conversion efficiency of 1.9%. The study is published in Nature Communications.
Harsh UV light is something most people try to avoid in summer, yet it is indispensable in fields ranging from air purification and resin curing in 3D printing to gel hardening in dental fillings and nail art. Despite its importance, UV accounts for only about 6% of the sunlight reaching Earth’s surface, with only a fraction of that being practically usable.
A cave in New Zealand has yielded fossils from a lost ecosystem that existed about 1 million years ago, including a possible flying ancestor of the kākāpō. The discovery reveals that volcanoes and climate upheaval were reshaping the country’s wildlife and driving extinctions long before humans arrived.
In 2012, I sat down with Dr. James Hughes, bioethicist, sociologist, and executive director of the Institute for Ethics and Emerging Technologies.
Fourteen years later, the questions we wrestled with have only sharpened.
Why are transhumanist atheists so often drawn to Buddhism? Is optimism rational, or just a posture we adopt to keep moving? What does it mean to redesign the human being, and which democratic institutions are ready to respond when we do?
James does not flinch from any of it. He talks about his first book Citizen Cyborg, the then forthcoming Cyborg Buddha, moral enhancement, animal uplift, and what our actual chances are of surviving the technological singularity.
What struck me most was his refusal to retreat into easy camps.
Not a cheerleader, not a doomsayer. Someone who interrogates the world and engages it on its own terms.
The critical minerals that power lithium-ion batteries are in high demand and short supply, especially for the U.S., which must rely on importing resources such as nickel and cobalt to manufacture the technology.
Cornell researchers have now developed a more efficient and cost-effective way to recover almost the full life of these batteries after they are spent. By using an electrochemical solution to regenerate their electrodes, the recycled batteries can regain up to 95% of their original power and last longer when reused, the researchers demonstrated.
The process could also slash current recycling costs by 56% and would be more environmentally friendly than current methods.
Astronomers have reported the discovery of an unusual X-ray transient detected by the Einstein Probe that does not fit any known class of cosmic explosions. The paper presenting its multiwavelength analysis was published in the journal Monthly Notices of the Royal Astronomical Society on June 13.
On March 5, 2024, a space telescope called the Einstein Probe—designed to scan the sky for sudden X-ray flashes—caught a brief, never-before-seen source called EP240305a. It produced two brief X-ray flares, one right after the other, separated by about 200 seconds of quiet.
Researchers quickly pointed several telescopes at this source to gather more data in X-rays, infrared, optical and radio wavelengths; the analysis of these multiwavelength data is presented in the new study.
In favorable climates, NVIDIA’s 45-degree liquid-cooling architecture can enable chiller-less operation with dry coolers, reducing facility cooling water consumption from roughly 2.6 million gallons per megawatt per year for conventional cooling-tower-based systems to near zero — up to a 100% reduction in water use.
The reason: traditional air-cooled data centers depend on large volumes of cooled air to remove heat from IT equipment, often requiring energy-intensive cooling infrastructure during hot weather. With NVIDIA’s 45-degree liquid cooling, heat is captured directly at the chip and transported through liquid loops operating at much higher temperatures, allowing outdoor dry coolers to reject heat efficiently for much of the year while significantly reducing mechanical cooling requirements and facility water consumption.
The data center ambient temperature is flexible — warm summer air is fine — because nothing in the server depends on cool air. The liquid does all the work — and the same liquid can be recirculated in a closed loop so no new water is consumed to cool the chips.
NVIDIA’s latest AI servers can run on coolant warmer than a hot tub — and that counterintuitive choice is one of the biggest efficiency leaps in data center history.
