A new artificial neuron that spikes like human brain cells could be used to process data at ultrafast speeds.
Blue Origin’s NS-29 mission will simulate the Moon’s gravity, testing 30 payloads focused on lunar tech. In partnership with NASA, the flight will provide critical data on six lunar technology areas: in-situ resource utilization, dust mitigation, habitation systems, sensors, small spacecraft, and entry descent/landing. For the first time, the New Shepard crew capsule will spin at 11 RPM, simulating lunar gravity, helping to lower the cost of space access. This testing supports NASA’s Artemis program, advancing innovation for future lunar exploration.
Scientists identified a new fungus, Gibellula attenboroughii, infecting cave spiders in Ireland. The fungus manipulates spider behavior, resembling “zombie-ant fungi.”
Dr. Harry Evans, Emeritus Fellow at CAB International, led a team of scientists—including experts from the Natural History Museum of Denmark and the Royal Botanic Gardens, Kew—in a study to identify a fungus discovered on a spider during the filming of the BBC Winterwatch series in Northern Ireland.
Through morphological and molecular analysis, the researchers confirmed the fungus as a previously unknown species.
Tissue processing advance can label proteins at the level of individual cells across whole, intact rodent brains and other large samples just as fast and uniformly as in dissociated single cells.
Scientists at UC San Francisco have pioneered a groundbreaking approach to fighting cancer using engineered fat cells.
By transforming ordinary fat into high-energy beige fat using CRISPR, they created a cell type that voraciously consumes nutrients — outcompeting and starving tumors.
Revolutionizing cancer treatment: engineered fat cells starve tumors.
Large-angle Lorentz Four-dimensional scanning transmission electron microscopy for simultaneous local magnetization, strain and structure mapping

The authors present an approach to simultaneously map local magnetization, strain, atomic structure at nanoscale. It provides direct visualization of strainmagnetic coupling in ferromagnetic materials, opening avenues for studying nanomagnetism.
Quantum field theory suggests that the very structure of the universe could change, altering cosmos as we know it. A new quantum machine might help probe this elusive phenomenon, while also helping improve quantum computers.
Nearly 50 years ago, quantum field theory researchers proposed that the universe exists in a “false vacuum”. This would mean that the stable appearance of the cosmos and its physical laws might be on the verge of collapse. The universe, according to this theory, could be transitioning to a “true vacuum” state.
The theory comes from predictions about the behaviour of the Higgs field associated with the Higgs boson, which Cosmos first looked at nearly a decade ago – the article is worth reading.
Using the MIRI instrument onboard the James Webb Space Telescope, an international team of scientists made the first-ever detection of a mid-IR flare from Sagittarius A*, the supermassive blackhole at the heart of the Milky Way. In simultaneous radio observations, the team found a radio counterpart of the flare lagging behind in time. The paper is published on the arXiv preprint server.
Scientists have been actively observing Sagittarius A* (Sgr A)—a supermassive black hole roughly 4 million times the mass of the sun— since the early 1990s. Sgr A regularly exhibits flares that can be observed in multiple wavelengths, allowing scientists to see different views of the same flare and better understand how it emits light and how the emission is generated. Despite a long history of successful observations, and even imaging of the cosmic beast by the Event Horizon Telescope in 2022, one crucial piece of the puzzle— mid-infrared observations (Mid-IR)—was missing until now.
Infrared (IR) light is a type of electromagnetic radiation that has longer wavelengths than visible light, but shorter wavelengths than radio light. Mid-IR sits in the middle of the infrared spectrum, and allows astronomers to observe objects, like flares, that are often difficult to observe in other wavelengths due to impenetrable dust. Until the recent study, no team had yet successfully detected Sgr A*’s variability in the mid-IR, leaving a gap in scientists’ understanding of what causes flares, and questions about whether theoretical models are complete.
