This Game-Changing Laser Is Smaller, Smarter, and Shockingly Powerful It’s faster, more affordable, and easier to tune than existing precision lasers. The breakthrough could transform technologies like Lidar in self-driving cars and gas detection systems. Laser Light Powers Modern Tech Laser technology plays a crucial role in modern science and engineering, especially in applications that rely on precise measurements or rapid data transfer. It is the foundation for technologies such as self-driving cars, fiber optic communication networks, and systems that monitor air quality by detecting trace gases. A team of researchers led by Associate Professor Johann Riemensberger from the Department of Electronic Systems at the Norwegian University of Science and Technology (NTNU) has now developed a new kind of laser designed to overcome several of the challenges found in current models. Compact and Cost-Effective Innovation “Our results can give us a new type of laser that is both fast, relatively cheap, powerful, and easy to use,” says Riemensberger. The findings, recently published in Nature Photonics, describe a major advance achieved through collaboration between NTNU, the Swiss École Polytechnique Fédérale de Lausanne (EPFL), and Luxtelligence SA. Self-Driving Cars and Air Quality Detectors Traditional precision lasers tend to be bulky, costly, and complicated to adjust. “Our new laser solves several of these problems,” says Riemensberger. This improvement opens the door for use in self-driving vehicles, which rely on a sensing method called Lidar to detect and measure the distance to nearby objects. Lidar works by analyzing the time it takes for light from the laser to reflect back or by detecting slight phase changes in the returning light wave. The new laser performs these measurements with remarkable accuracy, within roughly four centimeters. The researchers also achieved promising results when testing the device for detecting hydrogen cyanide gas in the atmosphere. This chemical, also known as “hydrocyanic acid,” is extremely poisonous even in small amounts, making rapid detection critical for safety and environmental protection.

The Holy Grail of Physics: Scientists Discover New Path to Room-Temperature Superconductors Electricity travels through wires to deliver power, but some of that energy is always lost along the way. However, that energy loss doesn’t have to happen. Researchers at Penn State have discovered a new method for identifying materials called superconductors, which can transmit electricity with zero resistance, allowing energy to move without any loss. The challenge is that superconductors are difficult to use in most real-world applications because they only function at extremely low temperatures. Such conditions make them impractical for technologies like next-generation energy systems or advanced electronics. Supported by the “Theory of Condensed Matter” program within the Basic Energy Science division of the Department of Energy (DOE), the Penn State team has created a new predictive approach that could help scientists discover superconductors capable of working at higher temperatures. According to Zi-Kui Liu, professor of materials science and engineering at Penn State, predicting which materials will become superconductors—especially those that operate at higher temperatures—remains a major scientific challenge. He explained that most researchers still believe existing theories of superconductivity apply only to materials that function at very low temperatures. “The goal has always been to raise the temperature at which superconductivity persists,” said Liu, who is lead author of a new study published in Superconductor Science and Technology. “But first, we need to understand exactly how superconductivity happens, and that is where our work comes in.” “We are not just explaining what is already known,” Liu said. “We are building a framework to discover something entirely new. If successful, the approach could lead to the discovery of high-temperature superconductors that work in practical settings, potentially even at room temperature if they exist. That kind of breakthrough could have an enormous impact on modern technology and energy systems.” Source:SciTechDaily @EverythingScience

#PPOD: Mar­tian Win­ter Won­der­land ❄️ This sweeping view along a rusty red ridge and into a crater showcases the exquisite beauty of icy, layered terrain in the south polar region on Mars.

Harvard Psychiatrist Says Mental Illness Starts in Your Cells Scientists have found that even before symptoms appear, these metabolic weaknesses can set the stage for conditions such as depression, bipolar disorder, and schizophrenia. The findings open the door to treatments that repair cellular function rather than simply adjusting neurotransmitters, marking a potential turning point in the prevention and management of psychiatric disorders worldwide. A Global Vision for Psychiatric Discovery In a recent Genomic Press interview featured in Genomic Psychiatry, Dr. Bruce M. Cohen discusses groundbreaking discoveries that are transforming how psychiatry understands and treats complex brain disorders. As the Robertson-Steele Professor of Psychiatry at Harvard Medical School and Director of the Program for Neuropsychiatric Research at McLean Hospital, Dr. Cohen reflects on nearly fifty years of research and places his work within a growing body of evidence that is redefining approaches to mental health care worldwide. Mitochondrial Mysteries Transform Treatment Paradigms The interview details how Dr. Cohen’s team has identified fundamental disruptions in cellular energy metabolism that appear to underlie major psychiatric conditions. These discoveries offer major promise for developing targeted treatments that could be applied across diverse populations. His studies demonstrate that brain cells derived from people with schizophrenia, bipolar disorder, and Alzheimer’s disease show intrinsic metabolic dysfunctions that may be corrected before illness symptoms develop. This metabolic perspective represents a fundamental shift from the neurotransmitter-based theories that have dominated psychiatry for decades. Dr. Cohen emphasizes that the brain depends more than any other organ on precise energy generation and cell-to-cell communication. His findings suggest that stabilizing these essential processes could help prevent or reduce psychiatric symptoms in at-risk individuals around the world. Dr. Cohen’s multidisciplinary research strategy integrates genomics, brain imaging, and cellular modeling to create a comprehensive view of mental illness. This unified framework is giving scientists new tools to better understand the biology of mood, psychotic, and cognitive disorders that affect people across cultures and continents.

SpaceX Falcon Heavy launch of private Griffin moon lander now targeting mid-2026 SpaceX's next mission to the moon, and the next launch of its triple-booster Falcon Heavy rocket, has slipped to no earlier than July 2026. Astrobotic's Griffin-1 lunar lander, carrying NASA and commercial payloads that include rovers from Astrobotic and Astrolab, will wait just a little longer before its planned excursion to the moon. The mission had previously targeted a launch at the end of 2025, but will apparently miss that deadline, according to an Astrobotic update posted on Oct. 24. The mission will mark Astrobotic’s second attempt at a lunar landing after its Peregrine Mission One in January 2024 failed to reach the moon after experiencing a propellant leak shortly after launch. Griffin is undergoing payload integration and software testing at the Pennsylvania company's facility, where propulsion testing and avionics validations are currently underway.

Mushrooms show promise as memory chips for future computers Fungal networks may be a promising alternative to tiny metal devices used in processing and storing digital memories and other computer data, according to a new study. Mushrooms have long been recognized for their extreme resilience and unique properties. Their innate abilities make them perfect specimens for bioelectronics, an emerging field that, for next-gen computing, could help develop exciting new materials. As one example, researchers from The Ohio State University recently discovered that common edible fungi, such as shiitake mushrooms, can be grown and trained to act as organic memristors, a type of data processor that can remember past electrical states. Their findings showed that these shiitake-based devices not only demonstrated similar reproducible memory effects to semiconductor-based chips but could also be used to create other types of low-cost, environmentally friendly, brain-inspired computing components. "Being able to develop microchips that mimic actual neural activity means you don't need a lot of power for standby or when the machine isn't being used," said John LaRocco, lead author of the study and a research scientist in psychiatry at Ohio State's College of Medicine. "That's something that can be a huge potential computational and economic advantage." Fungal electronics aren't a new concept, but they have become ideal candidates for developing sustainable computing systems, said LaRocco. This is because they minimize electrical waste by being biodegradable and cheaper to fabricate than conventional memristors and semiconductors, which often require costly rare-earth minerals and high amounts of energy from data centers. "Mycelium as a computing substrate has been explored before in less intuitive setups, but our work tries to push one of these memristive systems to its limits," he said.

COVID-19 mRNA vaccines can trigger the immune system to recognize and kill cancer, research finds The COVID-19 mRNA-based vaccines that saved 2.5 million lives globally during the pandemic could help spark the immune system to fight cancer. This is the surprising takeaway of a new study that we and our colleagues published in the journal Nature. While developing mRNA vaccines for patients with brain tumors in 2016, our team, led by pediatric oncologist Elias Sayour, discovered that mRNA can train immune systems to kill tumors — even if the mRNA is not related to cancer. Based on this finding, we hypothesized that mRNA vaccines designed to target the SARS-CoV-2 virus that causes COVID-19 might also have antitumor effects. So we looked at clinical outcomes for more than 1,000 late-stage melanoma and lung cancer patients treated with a type of immunotherapy called immune checkpoint inhibitors. This treatment is a common approach doctors use to train the immune system to kill cancer. It does this by blocking a protein that tumor cells make to turn off immune cells, enabling the immune system to continue killing cancer. Remarkably, patients who received either the Pfizer or Moderna mRNA-based COVID-19 vaccine within 100 days of starting immunotherapy were more than twice as likely to be alive after three years compared with those who didn't receive either vaccine. Surprisingly, patients with tumors that don't typically respond well to immunotherapy also saw very strong benefits, with nearly fivefold improvement in three-year overall survival. This link between improved survival and receiving a COVID-19 mRNA vaccine remained strong even after we controlled for factors like disease severity and co-occurring conditions. To understand the underlying mechanism, we turned to animal models. We found that COVID-19 mRNA vaccines act like an alarm, triggering the body's immune system to recognize and kill tumor cells and overcome the cancer's ability to turn off immune cells. When combined, vaccines and immune checkpoint inhibitors coordinate to unleash the full power of the immune system to kill cancer cells. Source:Live Science @EverythingScience

Yale Scientists Solve a Century-Old Brain Wave Mystery For more than a century, scientists have observed rhythmic waves of synchronized neuronal activity in the brain. Now, for the first time, researchers at Yale University have pinpointed where a specific type of this activity—known as gamma waves—originates and have linked it directly to behavior. Through the development of a highly precise new method for measuring brain activity, the team overcame long-standing technical barriers that had prevented a clear understanding of how these oscillations contribute to information processing and behavioral control.

Virtual reality can help people understand and care about distant communities For many of us, climate change feels like a distant threat—damage that will happen in the future somewhere far away to people we know little about. A new Stanford University-led study reveals how virtual reality can close that distance, enabling users to explore faraway places, develop a sense of attachment to those places, and care more about how a warming world is wreaking havoc on people's lives. The findings, published this week in Scientific Reports, show that VR experiences significantly reduce people's indifference to climate change-driven damages in faraway places compared to viewing static images. The findings demonstrate promise for bridging partisan gaps on the issue, and inspiring people to take constructive action, such as supporting pro-environment organizations and policies. "Virtual reality can make faraway climate impacts feel immediate and personally relevant," said study lead author Monique Santoso, a Ph.D. student in communication at the Stanford School of Humanities and Sciences. "By helping people form emotional attachments to distant places, VR fosters constructive emotions that motivate engagement rather than paralyzing fear." From indifference to action The new study involved 163 Stanford students who were randomly assigned to experience one of nine U.S. locations, such as New York City, Des Moines, Miami, and Massachusetts' North Shore, either through VR or static images. Participants listened to a news story about climate change-driven flooding in that location while virtually flying through a realistic 3D version of it. Source:Phys.org @EverythingScience
