Can philanthropy fast-track a flagship telescope?

Phys.org 

New Space is a term now commonly used around the rocketry and satellite industries to indicate a new, speed focused model of development that takes its cue from the Silicon Valley mindset of "move fast and (hopefully don't) break things." Given that several of the founders of rocketry and satellite companies have a Silicon Valley background, that probably shouldn't be a surprise, but the mindset has resulted in an exponential growth in the number of satellites in orbit, and also an exponential decrease in the cost of getting them to orbit.



How startups can communicate to win over silent audiences online

Phys.org 

A new study reveals how entrepreneurs can win support for their ideas from audiences who never speak up. The research shows that the way entrepreneurs engage with a few vocal participants in online discussions can crucially shape how the larger, silent audience perceives and supports their ideas.

It's been one year since wildfires devastated Los Angeles. What have we learned?

Phys.org 

The wildfires that ravaged Los Angeles a year ago were among the worst in California's history. They were exacerbated by persistent drought, a buildup of vegetation and Santa Ana winds which, at times, exceeded 80 mph. The most damaging fires, which reduced Altadena and Pacific Palisades to ashes, were finally extinguished on January 31, 2025.

Towards recycling of fiber composites: More sustainable epoxy thanks to phosphorus

Phys.org 

Most people are aware that plastic waste is a problem. Almost all types of plastics that we use in our everyday lives are derived from fossil sources. When they end up in the environment, they cause pollution for generations. When incinerated in a waste incineration plant, they release climate-warming CO₂ into the atmosphere. Recycling is therefore the better option: Used plastics provide the raw materials for new ones, closing the loop.



Uncovering a hidden mechanism in Met receptor activation

Phys.org 

Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, in collaboration with Osaka University and the National Institutes for Quantum Science and Technology, have uncovered a previously unknown mechanism behind the activation of the Met receptor—a key player in tissue regeneration and cancer progression.

Left in the cold: Study finds most renters shut out of energy-saving upgrades

Phys.org 

As winter heating costs rise, new research from Binghamton University, State University of New York reveals a cold truth. Renters—who make up approximately one-third of the U.S. population—are missing out on energy efficiency improvements that could lower their bills, make their apartments more comfortable and improve their health.

Lion conservation in Kenya: Why one approach does not fit all

Phys.org 

Lions in Kenya respond very differently to human land use, climate and conservation practices. That is the conclusion of thesis from Leiden biologist Monica Chege. A uniform approach is therefore insufficient. "Effective conservation only works when management is tailored to local conditions and developed with and around local communities."

Magnetic fields slow carbon migration in iron by altering energy barriers, study shows

Phys.org 

Professor Dallas Trinkle and colleagues have provided the first quantitative explanation for how magnetic fields slow carbon atom movement through iron, a phenomenon first observed in the 1970s but never fully understood. Published in Physical Review Letters, their computer simulations reveal that magnetic field alignment changes the energy barriers between atomic "cages," offering potential pathways to reduce the energy costs and CO2 emissions associated with steel processing.

Birding enthusiasts can help songbirds avoid Salmonella epidemics

Phys.org 

UCLA biologists are developing a tool to predict when deadly Salmonella outbreaks are likely to happen in wild songbird populations so that people can protect their feathered friends by taking down bird feeders at the right time. The research is published in Proceedings of the National Academy of Sciences.

Signs of ancient life turn up in an unexpected place

Phys.org 

Dr. Rowan Martindale, a paleoecologist and geobiologist at the University of Texas at Austin, was walking through the Dadès Valley in the Central High Atlas Mountains of Morocco when she saw something that literally stopped her in her tracks.

Deformable lens enables real-time correction of image aberrations in single-pixel microscopy

Phys.org 

Researchers from the Optics Group at the Universitat Jaume I in Castellón have managed to correct in real time problems related to image aberrations in single-pixel microscopy using a recent technology: programmable deformable lenses. The new method was described by the research team in an open-access article recently published in Nature Communications and is part of the development of the European CONcISE project.

Scientists demonstrate low-cost, high-quality lenses for super-resolution microscopy

Phys.org 

Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical components that enable super-resolution imaging, with each lens costing less than $1 to produce. The new fabrication approach is poised to broaden access to fully customizable optical parts and could enable completely new types of imaging tools.

Meta-analysis challenges the link between economic inequality and mental health

Phys.org 

Does living in an unequal society make people unhappy? Not necessarily, reveals the largest study ever conducted on the subject. Nicolas Sommet, a social psychologist and research manager at the LIVES Centre at the University of Lausanne, and his team have published the first social science meta-analysis in the journal Nature. Their conclusions—based on 168 studies covering more than 11 million participants from around the world—challenge the widely held belief that economic inequality is detrimental to well-being and mental health.
