Ancient skeletons reveal viruses embedded in human DNA

Scientists have, for the first time, rebuilt ancient genomes of Human betaherpesvirus 6A and 6B (HHV-6A/B) using DNA from archaeological human remains that are more than 2,000 years old. The research, led by teams at the University of Vienna and the University of Tartu (Estonia) and published in Science Advances,…

Magnetic nanoparticles fight bone cancer and help healing

Researchers from Brazil and Portugal have created a new magnetic nanocomposite designed to attack bone cancer while also supporting bone repair. The work, published in Magnetic Medicine, describes a core — shell structure made from iron oxide nanoparticles wrapped in a thin coating of bioactive glass. This design allows the…

A global cancer surge is underway and the world is not ready

Cancer cases are exploding worldwide — and nearly half of the deaths could be prevented with better prevention, early detection, and access to care. New cancer cases worldwide have more than doubled since 1990, reaching 18.5 million in 2023. Over the same period, annual cancer deaths rose by 74 percent…

Breakthrough lets scientists watch plants breathe in real time

Scientists have long understood that plants take in air through tiny openings on their leaves known as stomata. These microscopic pores act like adjustable valves, letting carbon dioxide enter the leaf for photosynthesis while allowing water vapor to escape into the air. Until now, closely tracking this balancing act as…

Wildfires are polluting the air far more than thought

As wildfires move across forests, grasslands, and peatlands, they release large amounts of gases and particles into the air. Scientists now say the pollution from these fires may have been underestimated. A study published in ACS’ Environmental Science & Technology reports that wildfires and prescribed burns (i.e., wildland fires) around…

Trump vuole la Groenlandia, pronto anche ad acquistarla – Notizie – Ansa.it

Il segretario di Stato Marco Rubio ha detto ai legislatori che le recenti minacce dell’amministrazione contro la Groenlandia non indicano un’invasione imminente e che l’obiettivo è acquistare l’isola dalla Danimarca: lo scrive il Wall Street Journal citando persone a conoscenza delle discussioni. Le dichiarazioni di Rubio sono arrivate durante un…

The simplest way teens can protect their mental health

Sleeping in on weekends to make up for lost sleep during the week may offer mental health benefits for teenagers and young adults, according to new research from the University of Oregon and the State University of New York Upstate Medical University. The study found that people ages 16 to…

Addio a Aldrich Ames, il peggior traditore della Cia – Nord America – Ansa.it

Aldrich H. Ames, l’ufficiale della Cia il cui spionaggio per Mosca ai tempi dell’Urss rappresentò la violazione più dannosa nella storia dell’agenzia di intelligence Usa, causando la morte di almeno 10 agenti reclutati dalla Cia stessa o da servizi di intelligence alleati, è morto il 5 gennaio al Federal Correctional…

11,000-year-old dog skulls reveal a hidden origin story

New archaeological research is reshaping our understanding of when domestic dogs first developed the wide range of shapes and sizes seen today. The study shows that dogs began to vary in form far earlier than scientists once believed, with clear signs of diversity appearing at least 11,000 years ago. Using…

This simple math trick could transform earthquake science

On December 6, 2025, a powerful 7.0 magnitude earthquake struck Alaska. While quakes of that size draw attention, earthquakes occur far more often than many people realize. The United States Geological Survey (USGS) estimates that roughly 55 earthquakes happen every day worldwide, adding up to about 20,000 each year. Typically,…

Harmful mouth bacteria may trigger Parkinson’s disease

There is a new reason to take daily tooth brushing seriously. Researchers in South Korea have found strong evidence that bacteria from the mouth can move into the gut and influence brain cells, potentially playing a role in the development of Parkinson’s disease. The study was carried out by a…

The poison frog that fooled scientists for decades

Scientists at the University of Kansas Biodiversity Institute and Natural History Museum recently uncovered a mistake that dates back decades involving a poison frog specimen from Peru. The frog had been incorrectly identified and designated as a holotype, which is the single preserved specimen used to officially define a species.…

Quantum structured light could transform secure communication and computing

An international research team that includes scientists from the UAB has published a new review in Nature Photonics examining a fast-growing field known as quantum structured light. This approach is reshaping how information can be transmitted, measured, and processed by merging quantum information science with carefully engineered patterns of light…

SETI watched a pulsar flicker for months and found space keeps shifting

For nearly a year, a research team led by the SETI Institute closely followed the pulsar PSR J0332+5434 (also called B0329+54). Their goal was to understand how the pulsar’s radio signal appears to “twinkle” as it travels through clouds of gas on its way to Earth. Using the Allen Telescope…

The invisible energy cost that keeps life from falling apart

Living systems pay energetic costs that traditional mechanical physics does not account for. One clear example is the energy needed to keep certain biochemical processes running, such as those involved in photosynthesis, while actively preventing other chemical reactions from taking place. In classical mechanics, if nothing moves, no work is…

Capotreno ucciso a Bologna, un fermo nel Bresciano  – Notizie – Ansa.it

Si è conclusa a Desenzano del Garda dopo poco più di 24 ore la fuga dell’uomo accusato di aver ucciso Alessandro Ambrosio, il capotreno 34enne, accoltellato all’addome ieri sera, apparentemente senza un perché, nel parcheggio del piazzale ovest della stazione di Bologna in un’area riservata ai dipendenti.
