Pelage Pharmaceuticals Announces Positive Phase 2a Clinical Trial Results for PP405 in Regenerative Hair Loss Therapy
Clinical validation of stem cell reactivation approach positions Pelage as leader in regenerative medicine and aging
LOS ANGELES—(BUSINESS WIRE)— #HairLoss —Pelage Pharmaceuticals, a clinical-stage regenerative medicine company, today announced positive results from its Phase 2a clinical trial of PP405 — a topical therapy for androgenetic alopecia advancing through the FDA clinical development pathway. PP405 is designed to reactivate dormant hair follicle stem cells, offering a potential first-in-class approach for both men and women experiencing hair loss.
Light-driven modulation of proximity-enhanced functionalities in hybrid nano-scale systems
Advancing quantum information and communication technology requires smaller and faster components with actively controllable functionalities. This work presents an all-optical strategy for dynamically modulating magnetic properties via proximity effects controlled by light. We demonstrate this concept using hybrid nanoscale systems composed of C₆₀ molecules proximitized to a cobalt metallic ferromagnetic surface, where proximity interactions are particularly strong. Our findings show that by inducing excitons in the C60 molecules with resonant ultrashort light pulses, we can significantly modify the interaction at the Cobalt/C60 interface, leading to a remarkable 60% transient shift in the frequency of the Co dipolar ferromagnetic resonance mode. This effect, detected via a specifically designed time-resolved Magneto-Optical Kerr Effect (tr-MOKE) experiment, persists on a timescale of hundreds of picoseconds. Since this frequency shift directly correlates with a transient change in the anisotropy field—an essential parameter for technological applications—our findings establish a new material platform for ultrafast optical control of magnetism at the nanoscale.
Proximity effects in molecule/metal heterostructures offer a promising route to control magnetic properties. Here, the authors report a light-controlled proximity effect at a Co/C₆₀ interface, where laser-induced excitons in C₆₀ alter interfacial interactions, leading to a 60% quenching of the ferromagnetic resonance frequency of Co.
Bat-Inspired AI-Powered Echolocation Technology Helps Drones Navigate in Darkness
In a remarkable leap forward for machine navigation, researchers funded by the U.S. Army have developed a synthetic echolocation system inspired by the natural sonar abilities of bats and dolphins.
This cutting-edge technology enables drones, autonomous vehicles, and robots to detect and identify objects in complete darkness, relying not on traditional visual sensors like cameras or LIDAR, but on ultrasonic pulses processed by artificial intelligence (AI). The result is a system that promises to transform how machines operate in low-visibility environments, offering new possibilities for military operations and civilian applications alike. From navigating smoke-filled battlefields to aiding search and rescue missions in disaster zones, this bioinspired innovation could reshape the future of autonomous systems.
The U.S. Army’s investment in this research, supported by the Army Research Office and the DEVCOM Ground Vehicle Systems Center, reflects a growing need for machines that can function effectively where human senses or conventional technology falter. By drawing on the way bats and dolphins use sound to perceive their surroundings, this system provides a robust alternative to light-dependent sensors, which struggle in conditions such as darkness, fog, or dust. Its potential extends beyond defence, with researchers envisioning its use in fields as varied as medical imaging, industrial inspection, and underwater exploration. What makes this development particularly exciting is not just its versatility, but the clever way it was created—using simulated data to train AI, paving the way for a cost-effective and adaptable solution.
Turkish firm unveils world’s 1st low-altitude multipurpose drone at defense expo in Istanbul
Turkish firm Solid Aero unveiled the Talay unmanned aerial vehicle, which was introduced as the world’s first low-altitude multipurpose UAV last year, on the global stage with a production-ready model at the International Defense Industry Fair (IDEF 2025) in Istanbul.
The Talay UAV was introduced at the SAHA Expo last year. The craft will enter mass production once its maritime test missions are completed.
The aircraft proved itself with its free flight capacity at a 100-meter altitude using the “Wing-in-Ground” principle.
Solid Aero will soon begin the testing and production of the craft in collaboration with Istanbul-based Yonca Shipyard.
The Talay UAV was developed to be used for low-altitude operations over sea as an effective and high-performance platform for defense, attack, and deterrence missions.#

Photonaire develop laser propulsion
Imagine a drone that glides through the air without the familiar buzz of propellers or the hum of motors, a machine so quiet and still that it seems to defy the very principles of flight. This is no longer a vision confined to science fiction. A French startup, Photonaire, based in the vibrant city of Lyon, has brought this concept to life with a drone that flies using nothing but light.
By tapping into the power of concentrated laser beams, this groundbreaking invention generates thrust through a phenomenon known as “optical lift,” offering a glimpse into a future where aerial and space technology could be transformed. Photonaire’s creation weighs a mere 90 grams, a featherweight by any standard, yet it carries the weight of innovation on its delicate frame.
Unlike traditional drones that rely on mechanical components to lift off and manoeuvre, this device uses high-powered lasers reflected off ultra-thin metamaterials—materials engineered with precision to harness light in ways that conventional substances cannot. Drawing inspiration from solar sail technology, which uses sunlight to propel spacecraft, and the subtle forces of quantum pressure, the drone hovers and adjusts its path by altering the angle of these reflective surfaces in real time.
Scientists reconstruct 10,500-year-old woman’s face using DNA
Researchers studying the remains of a prehistoric woman who lived around 10,500 years ago in what is now Belgium have produced a reconstruction of her face using ancient DNA.
A team led by scientists from Ghent University found that the woman would have had blue eyes and slightly lighter skin than most other people from the Mesolithic period in Western Europe who have been analyzed to date, according to a statement from the university on Tuesday.
Isabelle De Groote, an archaeologist at Ghent University who leads the research project on Mesolithic Belgium, told CNN that the woman came from the same population group as the Cheddar Man, who lived in what is now the United Kingdom at around the same time, but had lighter skin.
