Why move antimatter by road? CERN tests a truck-ready antiproton trap
Scientists in Geneva are taking some antiprotons out for a spin—a very delicate one—in a truck, in a never-tried-before test drive.

XRISM identifies gamma Cas X-ray origin, solving a 50-year-old stellar mystery
Visible to the naked eye in the constellation Cassiopeia, the star γ Cas has puzzled astrophysicists for half a century. It emits X-rays of an intensity and temperature incompatible with what one would expect from an ordinary massive star. Observations, carried out using the Resolve instrument aboard the Japanese XRISM telescope, now allow us to attribute this emission to the white dwarf orbiting γ Cas. This also confirms the existence of a family of binary systems long predicted to exist but never identified.

Nanoparticles enable large-scale production of advanced cell therapies
Researchers from Xi'an Jiaotong-Liverpool University (XJTLU) in China have developed a streamlined process that makes it easier to produce tiny therapeutic particles released by cells, called exosomes, which are being explored as a new type of medical treatment. Using a nanoparticle-based system, the researchers were able to overcome a major barrier that has slowed the medical and industrial deployment of these therapies. Their findings were published in the journal Advanced Science.

Agricultural soils exposed to controversial weedkiller may be unexpected breeding ground for hospital 'superbugs'
Each year, antimicrobial resistance (AMR) is responsible for an estimated 1.1 to 1.4 million deaths worldwide. Now, scientists have found evidence that the spread of AMR isn't always driven by bacteria evolving to resist the antibiotics themselves: rather, certain weedkillers can have the same effect.

When NASA's experimental technology detects a tsunami, it may help save lives
A new data visualization illustrates how an experimental NASA technology can provide extra lead time to communities in the path of a tsunami. Called GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network), the software detects slight distortions in satellite navigation signals to spot hazards on the move.

Yes, AI could boost productivity, but work is about more than maximizing output
Worries about the British economy have long been dominated by one persistent concern—weak productivity. Since the financial crisis of 2008, growth has stagnated, leaving the UK trailing well behind the US, France and Germany across that whole period.

Why a canceled meeting feels so liberating
Unless your employer is Lumon Industries, where the "Severance" workday never ends, a canceled meeting can feel like a gift of limitless time. A Rutgers University study published in the Journal of the Association for Consumer Research explains why: Unexpectedly gaining time alters our perception of how that time passes, which in turn affects how we spend it.

In Hollywood, teams don't stick together long enough to learn from failure, data reveal
Hollywood loves a comeback story: a director who flopped and then returned with a masterpiece or the producer who went bust and bounced back with a winner. It's a narrative rooted in the business belief that failure is a great teacher. But what if, for certain teams, failure teaches nothing at all?

Research suggests negative emotions at work can help, depending on leaders' empathy
During a widespread crisis, negative emotions don't simply go away once the workday begins. Organizational scholars who study how emotions affect employees tend to assume that negative emotions equal negative outcomes. That isn't always the case, according to new research from David Lebel, associate professor of business administration in the School of Business and director of the Berg Center for Ethics & Leadership.

Adding 1,000 immigrants tied to 142 more health workers, fewer elderly deaths
New research finds the addition of a thousand new immigrants in a metropolitan area reduces elderly mortality by about 10 deaths than would be typical. Why? Because among the newcomers are foreign-born health care workers who are arriving amid a critical nationwide shortage, according to the study's authors, who hail from Harvard Medical School, the Massachusetts Institute of Technology, and the University of Rochester.
