A small international team of nanotechnologists, engineers and physicists has developed a way to force laser light into becoming a supersolid. Their paper is published in the journal Nature. The editors at Nature have published a Research Briefing in the same issue summarizing the work.

Supersolids are entities that exist only in the quantum world, and, up until now, they have all been made using . Prior research has shown that they have zero viscosity and are formed in crystal-like structures similar to the way atoms are arranged in salt crystals.

Because of their nature, supersolids have been created in extremely cold environments where the can be seen. Notably, one of the team members on this new effort was part of the team that demonstrated more than a decade ago that light could become a fluid under the right set of circumstances.

Neutrinos generated through solar fusion reactions travel effortlessly through the sun’s dense core. Each specific fusion process creates neutrinos with distinctive signatures, potentially providing a method to examine the sun’s internal structure. Multiple neutrino detection observatories on Earth are now capturing these solar particles, which can be analyzed alongside reactor-produced neutrinos with the data eventually enabling researchers to construct a detailed map of the interior of the sun.

The sun is a massive sphere of hot plasma at the center of our solar system and provides the light and heat to make life on Earth possible. Composed mostly of hydrogen and helium, it generates energy through , converting hydrogen into helium in its core. This process releases an enormous amount of energy which we perceive as heat and light.

The sun’s surface, or photosphere, is around 5,500°C, while its core reaches over 15 million°C. It influences everything from our climate to space weather, sending out and occasional bursts of radiation known as . As an average middle-aged star, the sun is about 4.6 billion years old and will (hopefully) continue burning for another 5 billion years before evolving into a red giant and eventually becoming a white dwarf.

Traditional microscopy often relies on labeling samples with dyes, but this process is costly and time-consuming. To overcome these limitations, researchers have developed a computational quantitative phase imaging (QPI) method using chromatic aberration and generative AI.

By leveraging the natural variations in focus distances of different wavelengths, the technique constructs through-focus image stacks from a single exposure. With the help of a specially trained diffusion model, this approach enables high-quality imaging of biological specimens, including real-world clinical samples like red blood cells. The breakthrough could revolutionize diagnostics, providing an accessible and efficient alternative to conventional imaging techniques.

Revealing Insights Without Labels

Researchers found that fundamental constants determine the upper limit of superconducting temperatures, and luckily, our Universe allows for conditions where this breakthrough might be possible.

The Holy Grail of Physics: Room-Temperature Superconductivity

A new study, published on March 3 in the Journal of Physics: Condensed Matter, suggests that room-temperature superconductivity — long considered the “holy grail” of condensed matter physics — may indeed be possible within the fundamental laws of the universe.

A stressful life can leave marks on our genetic code, some of which can even be passed on to our children. A study now reveals how the biological impact of trauma on a mother persists long after the violent acts themselves have passed.

The international team of researchers demonstrate the physical mechanisms behind intergenerational trauma in humans, explaining why people with a family history of adversity are more prone to mental health conditions like anxiety and depression, despite not having experienced the adverse events themselves.

The researchers analyzed DNA collected from 48 Syrian families across three generations. These families included grandmothers or mothers who while pregnant had fled the 1982 siege and massacre in Hama or the 2011 armed uprising – both part of the ongoing Syrian civil war.

A newly devised “polymorphic” attack allows malicious Chrome extensions to morph into other browser extensions, including password managers, crypto wallets, and banking apps, to steal sensitive information.

The attack was devised by SquareX Labs, which warns of its practicality and feasibility on the latest version of Chrome. The researchers have responsibly disclosed the attack to Google.

The Akira ransomware gang was spotted using an unsecured webcam to launch encryption attacks on a victim’s network, effectively circumventing Endpoint Detection and Response (EDR), which was blocking the encryptor in Windows.

Cybersecurity firm S-RM team discovered the unusual attack method during a recent incident response at one of their clients.

Notably, Akira only pivoted to the webcam after attempting to deploy encryptors on Windows, which were blocked by the victim’s EDR solution.

Microsoft has taken down an undisclosed number of GitHub repositories used in a massive malvertising campaign that impacted almost one million devices worldwide.

The company’s threat analysts detected these attacks in early December 2024 after observing multiple devices downloading malware from GitHub repos, malware that was later used to deploy a string of various other payloads on compromised systems.

After analyzing the campaign, they discovered that the attackers injected ads into videos on illegal pirated streaming websites that redirect potential victims to malicious GitHub repositories under their control.
