One-step rapid syphilis test uses layered nanoparticles to detect infection earlier

Penicillin has cured syphilis cases since 1943, but symptoms of the sexually transmitted infection, known as "the great imitator," mimic many other diseases and can come and go without treatment while the infection keeps causing harm. If it remains undetected, it can spread to partners and to babies during pregnancy, causing lifelong effects.

Can social media bans protect young people's mental health? Early research suggests that bans aren't the answer

The year 2026 has been an expensive one for social media platforms. Since March, YouTube and Meta, the parent company of Instagram and Facebook, have settled or paid out in multiple lawsuits totaling more than $17 billion for allegedly acting negligently, deliberately designing their platforms to hook kids and misleading the public about safety and privacy. If these suits are any indication of how states and the public are starting to view social media platforms, more may follow.

Physics-guided AI reconstructs hidden patterns inside ultrathin magnets from external fields

To build faster and more energy-efficient computers, researchers need to understand nanoscale magnetic materials. But looking inside these tiny magnets is surprisingly difficult: Modern microscopes only measure the magnetic field outside the material, not the magnetic pattern inside. Because many different internal patterns can produce the exact same field, working backwards has long been a challenge.

Fossil of 'unconquered female warrior' dinosaur with long claws found in UK museum drawer after 100 years

A fossil that sat in a museum collection for over a century is a previously unknown species of predatory dinosaur, researchers have found. The discovery could help scientists solve a longstanding mystery about how some of the Cretaceous period's most formidable hunters spread around the globe. The dinosaur lived on what is now the Isle of Wight in southern England about 120 million years ago. It belonged to a group of two-legged carnivores called megaraptors, which are related to tyrannosaurs. But unlike tyrannousars, megaraptors are thought to have relied on their powerful arms and large curved claws to attack prey and defend themselves. The newly identified species was described in an Oct....

Forecasting air drag with deep learning helps predict when uncontrolled satellites and rocket stages fall to Earth

On May 10, 2025, a spacecraft built in the Soviet Union to land on Venus came home. Launched in 1972, Cosmos-482 was stranded by a failed upper stage of its rocket and circled Earth for 53 years. In its last days, several space agencies and research groups forecasted when it would fall, and therefore where. Roscosmos later reported that it came down in the Indian Ocean, west of Jakarta.

Fully automated testing of bulk metals paves the way for AI-driven materials development

Developing stronger and tougher structural metals such as steel requires exploring an enormous range of processing conditions. Even for the same alloy composition, heat treatment can dramatically change the material's microstructure and mechanical properties. If there were a way to automate the process, we could pinpoint ideal conditions much more efficiently. However, experiments on bulk metallic materials are difficult to automate because they require handling solid specimens and integrating large, specialized equipment.

How do combined sewer overflows affect water quality in Philadelphia?

In Philadelphia and many urban areas across the U.S. with sewer systems dating back to the 1800s, more frequent flooding is posing a threat not only to people and property but also to surrounding ecosystems. In these areas, stormwater and sewage drain into the same pipes, which are designed to spill into nearby waterways when flooding occurs rather than inundating streets.

Fraudulent paper mills may be manipulating scientific citations and amplifying unreliable findings

The likely manipulation of citation numbers by research paper mills in high-impact cancer journals has been uncovered by an international team of academic researchers. Their findings point to an organized campaign to inflate citations on paper mill–produced journal articles published in established molecular oncology journals.

Scientists have just voted to abolish leap seconds

The Schiphol Clock, in Amsterdam’s airportPanther Media Global/Alamy Leap seconds, previously used to keep the world’s clocks in sync with Earth’s rotation, are to be abolished. Instead, universal time will be allowed to drift up to an hour from astronomical time before it is corrected. Representatives from 69 countries voted for the change on 15 October at a meeting of the International Bureau of Weights and Measures (BIPM) in Versailles, France. As the gap between clock time and astronomical time slowly grows, the effect will eventually be β€œlike living on daylight saving time”, but permanently, says Emily Akkermans, curator of time at the Royal Observatory in Greenwich, London. For most of...

Kids and teens are going to AI chatbots for advice. How can parents make sure this is safe?

Last week, Australian Federal Police Commissioner Krissy Barrett warned artificial intelligence (AI) chatbots are not a sufficient replacement for human support for children. The comment was in response to a recent Adelaide University study that found more than one in three Australian children turn to AI chatbots for support when they are sexually victimized online or otherwise tell nobody at all.

The force behind our strength: How mechanical processes regulate muscle development

Skeletal muscles grow and regenerate as individual precursor cellsβ€”called myoblastsβ€”fuse into long fibers from which mature muscle fibers develop. How they coordinate this process and form functional muscles is not yet fully understood. A research team at the Max-Planck-Zentrum für Physik und Medizin (MPZPM) has now shown that mechanical stress influences the fusion of muscle cells.

AI and wastewater DNA-based mapping help identify sewer pipes at risk of corrosion

Underground sewers that safely manage wastewater are essential to modern cities. However, since they are buried underground and difficult to access, their condition can be hard to monitor. Traditional camera inspections are costly and time-consuming, but we need regular inspections so aging pipes do not continue to deteriorate until they reach a breaking point. When damaged pipes leak, they can pose serious risks to public health by contaminating surrounding water, while more severe failures can even damage infrastructure above them, causing sinkholes in city streets.
