Seeing is believing: Smart probes reveal proteins inside living cells with unprecedented clarity‎

Fluorescent probes have transformed modern biology by allowing researchers to tag and visualize individual molecules in living cells, tissues, and animals. Using these tools, researchers can watch viruses infect cells in real time, observe cellular trash collection, and track the signaling that spurs tumor growth. Now, scientists at Albert Einstein College of Medicine and the Salk Institute for Biological Studies have developed a new molecular imaging technology that illuminates proteins inside living cells and animals far more clearly than before. Described in Nature Methods, the system uses engineered fluorescent nanobodies—tiny antibody-like protein fragments—that light up only when they bind to their specific targets.

Monkeys in Gibraltar self-medicate with soil to help them digest tourists' junk food‎

Monkeys in a tourism hotspot have learned that swallowing dirt can quell the upset stomachs caused by overconsumption of sweet and salty snacks fed to them by holidaymakers, a new University of Cambridge-led study suggests. Troops of macaques living on Gibraltar—the only free-ranging monkey population in Europe—have been scientifically observed for the first time regularly engaging in geophagy, the practice of intentionally ingesting soil. The work appears in Scientific Reports.

Sun simulations reveal how cool prominences survive in million-degree corona‎

At more than one million degrees, the sun's atmosphere—the corona—is incredibly hot; but not everywhere. Time and again, huge structures of significantly cooler solar plasma—about 10,000 degrees—appear within the corona. These structures are known as prominences. They span up to several thousand kilometers and often resemble flickering flames that can take on a wide variety of shapes. Despite their delicate appearance, they are massive "chunks of matter": their density exceeds that of the surrounding corona by more than a hundred.

Plants can sense the sound of rain, new study finds‎

The next time you find yourself lulled by the patter of rain outside your window, think how that same sprinkle might sound if you were a tiny seed planted directly below a free-falling droplet. Would you still be similarly soothed? In fact, MIT engineers have found the opposite to be the case: Some seeds may come alive to the sound of rain. In experiments with rice seeds, the team found that the sound of falling droplets effectively shook the seeds out of a dormant state, stimulating them to germinate at a faster rate compared with seeds that were not exposed to the same sound vibrations.

Which 'money type' are you? New research maps financial habits of young Australians‎

Under 35, navigating the cost-of-living and trying to get ahead? New research from Southern Cross University, QUT and Griffith University challenges the idea that financial literacy alone addresses this problem. Instead, three distinct "money behavior types" among young Australians are linked to different financial outcomes.

When a spouse starts a business, the other partner pays a hidden price‎

When an entrepreneur leaves a salaried job to pursue a venture, the conversation nearly always centers on them: the risk they're taking, the opportunity they're pursuing and the funding they need.

Improving scientific accuracy in journalism‎

Journalists bring scientific findings to the public, and to policymakers, who often rely on media reports rather than primary literature to provide context for policymaking. However, media reports can and often do distort scientific findings. Reporters with little scientific training, working quickly, and keen to attract eyeballs and clicks, can sometimes misrepresent science.

As the world faces yet another crisis, why are leaders still resisting remote work?‎

At 9 p.m., shops, restaurants and cafes go dark across the city of Cairo, where a stringent curfew has been imposed to mitigate the energy shock triggered by the conflict in the Gulf. The measure may prove difficult to enforce among people accustomed to long, convivial evenings, but the outlook is far from reassuring. Reports from inland areas indicate that petrol stations are running dry, raising fears that the emergency will last longer than expected.

Rethinking energy transition participation: Why citizens are more than a box to tick‎

Citizen participation is widely seen as key to a successful energy transition. In practice, however, it often remains more of an ideal than a reality. In her Ph.D. research at TU/e, Nikki Kluskens shows just how wide the gap is between that ideal and everyday practice—and why we need to rethink how we approach public engagement.
