Zika virus assembles without protein segment long deemed essential

For years, scientists were certain that two factors were involved in the assembly of active, highly infectious Zika viruses in human cells: a specific viral protein in its entirety and a turncoat human enzyme that assured viral maturity. New research suggests that Zika virus has been far less reliant on those components than previously thought.

Curiosity's top 10 photos of Mars after 5,000 days of exploration

As of Aug. 30, 2026, NASA's Curiosity rover has officially seen the sun rise and set over Mars' reddish horizon more than 5,000 times in its quest to discover if life ever existed there. The rover was originally planned to operate for only two years, but the mission is still going strong more than 14 years after landing on Mars in August 2012. During that time, the rover has weathered global dust storms and climbed more than 3,200 feet (1,000 meters) up a mountain — although its tires have gotten some rather large holes in them in the process. The rover still uses its 17 cameras to take hundreds of photos every single sol (Martian day), beaming a total of more than 780,000 photos back to Ear...

Why Viking museums still can’t escape the warrior myth

Scandinavian museums are trying to move beyond the familiar image of Vikings as sword-wielding male warriors, highlighting women, farmers, traders, and a far more complicated society. But the enduring popularity of the Viking myth means exhibitions often balance historical accuracy with stories that reflect modern ideas about national identity and culture.

Stonehenge’s 6-ton altar stone may have traveled from Scotland by glacier

Stonehenge’s six-ton Altar Stone may have been carried from Scotland to Dogger Bank by glaciers before prehistoric people transported it hundreds of kilometers to Salisbury Plain. The possible multistage journey suggests remarkable organization and raises the possibility that the stone was valued long before it became part of Stonehenge.

Pigeons' proposed inner-ear compass runs into a noise problem

A pigeon turning its head might seem an unlikely electricity generator. Yet one proposed explanation for the bird's magnetic sense depends on exactly that: Turning through Earth's magnetic field would produce tiny electrical signals inside its ears. However, a theoretical study suggests that this miniature generator cannot supply directional information fast enough to work as a compass. The problem is electrical noise produced within the proposed sensor itself.

Weird spikes poking through a teen's eyelid turned out to be a wayward tooth

The patient: A 16-year-old boy in IndiaThe symptoms: The teen developed swelling on his left upper eyelid that persisted for a few months but was painless. However, he later noticed two sharp, white projections poking out from the skin above his eye. About a month after these projections appeared, he went to a hospital. What happened next: Doctors examined the teen's eyelid, noting that the spikes had a "fairly smooth surface and were hard on palpation," said Dr. Meghana Tanwar, a medical consultant at the Aravind Eye Hospital in India who co-authored a report of the case. The texture and color of the projections suggested they might be teeth, she told Live Science in an email.Initially, the...

'Risk-free' matched betting? More than half of surveyed users report losses

A new peer-reviewed study from Bournemouth University has found a striking gap between how people perceive the risks of matched betting and what some experience in practice. Matched betting involves using free bets given out by online gambling companies as a promotion to attract new customers. This allows people to bet on different results for the same event, such as a football match. It is frequently promoted online as a controlled or even 'risk-free' way of making money.

Snapshots reveal key molecular machine in tropical parasites at near-atomic resolution

A study conducted by the University of Liège and Rockefeller University reveals, with near-atomic precision, the three-dimensional structure and function of a gigantic molecular machine essential to the survival of trypanosomatid parasites, which cause serious diseases in humans, animals and plants. The work has been published in Nature Communications.

The hunt for extraterrestrial life is fundamentally flawed. But there's a fix.

The hunt for extraterrestrial life on distant planets may be operating with a big blind spot. That's because we aren't accounting for the nature of the light coming from the host star itself when we interpret the chemical signatures of life, or biosignatures, on some of the most promising candidate planets beyond the solar system. If we don't consider that crucial factor, we could be led on a wild-goose chase across the cosmos.Despite having discovered thousands of exoplanets, we have not detected convincing evidence of alien life on any of them. But astronomy is reaching a point where powerful telescopes can zoom in on many more potentially habitable worlds. Planets that orbit M dwarfs, whi...

Livestock grazing may boost soil carbon storage in Iceland's subarctic grasslands

Grassland plants transfer large amounts of carbon to soil through their roots, and most of that carbon is stored underground. Therefore, promoting soil carbon storage can help combat climate change. Grazers feed on grassland plants, and conventional wisdom often assumes that removing grazers benefits carbon storage, but a new study in Global Change Biology Communications reveals that the opposite may be the case.

Scientists say a critical Atlantic Ocean current is weakening and the effects could be global

Scientists have found strong observational evidence that a key part of the Atlantic Meridional Overturning Circulation has been weakening across a wide stretch of ocean for nearly two decades. The slowdown could eventually reshape weather patterns, rainfall, storms, winters, and coastal sea levels around the Atlantic.

FUNdaMENTALs of precision design

Repeatability in engineering product design ensures that a manufacturing process performs the same way every time and allows for a working prototype to be transformed into a reliable, safe, consistent, and cost-effective mass-market product. For students in class 2.70 (Fundamentals of Precision Product Design), precision and repeatability are the name of the game. “[As an engineer], you have an extra responsibility to overlook nothing,” says course instructor Alex Slocum, the Walter M. and A. Hazel May Professor of Mechanical Engineering. “If you miss something, someone could be hurt or die.”Slocum’s message is serious, but his approach to teaching the material is famously fun — in fact, he ...

Research project identifies pathways to climate-resilient water and soil management

How can regions better adapt their water and soil resources to the impacts of climate change? After four years of research, the European collaborative project Blue Transition, led by the LIAG Institute for Applied Geophysics in Hanover, takes stock. The final report brings together the findings from 16 pilot regions in six countries and identifies three key levers to strengthen climate resilience: changing land use, improving soil health and diversifying water resources and optimizing their use.
