MIT physicists created a long-lasting magnetic state in a material, using only light. The results provide a new way to control and switch antiferromagnetic materials, which are of interest for their potential to advance information processing and memory chip technology.
PV modules are cheap enough today that the simple fixed East-West arrays are cheaper and faster to install than the industry’s darling, the single-axis tracked array. Xavier Dedenbach, Terraform Po…
Lyme disease is caused by the bacterium Borrelia burgdorferi, which relies on the antioxidant manganese to protect it from its host’s immune system. Both removing or adding too much manganese weakens the bacteria. Disrupting this balance could lead to new treatments for Lyme disease.<br />
In a first for space cuisine, ESA project astronaut Sławosz Uznański-Wiśniewski will bring pierogi, the traditional Polish dumplings, to the International Space Station during the upcoming Axiom Mission 4.
Using Apple Watch noise and sleep stages to quantify the effect of noise on sleep
The emerging importance of the find underscores a key truth about archaeology: artifacts often hold secrets that only later generations can unlock.
UH researchers uncovered the tomb of Te K’ab Chaak, founder of Caracol’s royal dynasty. The find includes jadeite treasures, rare pottery and evidence of early ties between the Maya and Teotihuacan, reshaping understanding of Mesoamerican history.
When Mr Lewin began explaining how cartographers addressed the challenge of portraying what is essentially a three dimensional object - the world - on a two dimensional plane - a piece of paper - my eyes lit up!
NYU Langone study shows that oral bacteria and fungi involved in gum disease may also increase risk for pancreatic cancer more than threefold. Learn more.
New findings from studying over two decades of satellite observations reveal that the Earth’s continents have experienced unprecedented freshwater loss since 2002, driven by climate change, unsustainable groundwater use and extreme droughts.
Earth AI is helping enterprises and cities with everything from environmental monitoring to disaster response.
A 2026 Airline Water Study released today by the Center for Food as Medicine and Longevity reveals that the quality of drinking water varies significantly by airline, and many airlines…
AN EXTREMELY RARE “MEGALOGRAPHY” OF THE 1ST CENTURY BC, LIKE THE FAMOUS VILLA OF THE MYSTERIES Over 100 years since the discovery of the Villa of the Mysteries, a large … keep it going
A new study reveals that air pollution, traditional herbal medicines and other environmental exposures are linked to genetic mutations that may contribute to the development of lung cancer in people with no or hardly any history of smoking.
EPFL researchers have developed a new way to design complex, curved three-dimensional shapes using flat materials such as paper, aluminum sheets or plastic, combining creative thinking with a new computational algorithm.
For some time, I’ve argued that a common conception of AI is misguided. This is the idea that AI systems like large language and vision models are individual intelligent agents, analogous to human agents. Instead, I’ve argued that these models are “cultural technologies” like writing, print, pictures, libraries…
New analysis finds tests for new doctors can measure what matters — the life and health of patients
A figure from the study showing rock dripping from the craton. The researchers hypothesize that the dripping is caused by…
In a world first, a team led by researchers at Penn State used two-dimensional materials, which are only an atom thick and retain their properties at that scale, unlike silicon, to develop a computer capable of simple operations. The advancement, published in Nature, represents a major leap toward the realization of…
Getting zapped with millions of volts of electricity may not sound like a healthy activity, but for some trees, it is, according to a new study. Published in New Phytologist, the study finds that some tropical tree species are not only able to tolerate lightning strikes, but benefit from them. The trees may have even…
Using EEG readings of brain waves to monitor unconsciousness, an anesthesiologist can significantly reduce the amount of the anesthesia administered to safely induce and sustain the anesthetized state of children undergoing surgery.
Throughout the 20th century, as most of the world warmed, the eastern US remained mysteriously cool. Now, scientists think they have an explanation: trees.
An MIT-led study confirms the Antarctic ozone layer is healing as a direct result of global efforts to reduce ozone-depleting substances.
Researchers from the Bakkers group at the Hubrecht Institute have successfully repaired damaged mouse hearts using a protein from zebrafish.
Released today, a report of a study investigating the project’s feasibility will serve as input for the European Strategy for Particle Physics and be assessed by the CERN Council in the coming months
We advertise 100 kHz as the lower edge of HackRF Pro ’s operating frequency range, but that isn’t a hard limit. While working on the design, I realized that it should work fairly well to pick up longwave time signals such as WWVB , broadcast at 60 kHz from Colorado, USA.
