Unlike modern crocodiles, which mostly lurk in rivers and swamps, mekosuchines were an extraordinarily diverse and adaptable group. They filled ecological roles unlike any reptiles alive today. Some species were small and land-dwelling, while others may have hunted in forests rather than waterways.

Researchers used an AI based on GPT architecture to map the brain, and they found it’s way more complex than we thought. Instead of the ~52 broad regions we’ve been working with, the AI identified about 1,300 distinct areas.

Big Crunch, here we come! A new study is implying that the universe may actually be slowing down and that the culmination of the decrease in dark energy could spell a reverse big bang.

Electrons inside solid materials behave in a surprisingly similar way. When they gain extra energy (for instance, when the material is struck by other electrons), they can sometimes break free from the solid. This process has been known for decades and forms the basis of many technologies. However, until recently, scientists had been unable to calculate it with precision. Researchers from several groups at TU Wien have now found the solution. Just as the frog must find the right opening, an electron also needs to locate a specific “exit,” known as a “doorway state.”

Using social media as an example, universities have a strong interest in promoting the work being done at their campuses far and wide. This is where traditional platforms fall short: algorithms typically prioritizing paid content, downrank off-site links, and prioritize sensational claims to drive engagement. When users are free from enshittification and can themselves control the platform’s algorithms, as they can on platforms like Bluesky, scientists get more engagement and find interactions are more useful.

A team of physicists led by Mir Faizal at the University of British Columbia has demonstrated that the universe cannot be a computer simulation, according to research published in October 2025[^1].

The CMS collaboration at CERN’s Large Hadron Collider has observed an unexpected excess of top quark-antiquark pairs that could indicate the existence of toponium - potentially the smallest composite particle yet discovered[^1].

Chemists from the University of Warwick and Monash University have discovered a powerful new antibiotic called pre-methylenomycin C lactone, found as an intermediate compound in the production of methylenomycin A[^1]. This molecule shows remarkable potency against drug-resistant bacteria, demonstrating over 100 times greater activity against Gram-positive pathogens compared to methylenomycin A[^2].

The Earth’s magnetosphere acts as a protective shield against the solar wind—a stream of charged particles from the Sun. This interaction results in a large-scale electric field in the magnetosphere, known as a dawn-dusk convection electric field, playing a crucial role in disturbances such as the storm-time ring current and substorms. We explored the quasi-steady large-scale electric fields and the role of space charge in the magnetosphere by using global magnetohydrodynamics (MHD) simulations. When the interplanetary magnetic field is southward, a substorm growth phase begins. The large-scale electric field is in a relatively stable condition, in particular, on the dayside. In the MHD simulation, the positive space charge dominates the duskside magnetosphere, while the negative space charge dominates the dawnside. If the electric field is purely caused by the space charge deposited in the magnetosphere, the direction of the electric field will be in the dusk-dawn direction. However, the dawn-dusk electric field is established in the magnetosphere due to continued plasma motion interacting with the magnetic field. It is suggested that the magnetosphere maintains dynamic equilibrium through a balance of energy flow from the solar wind to the ionosphere. These insights improve our understanding of magnetospheric convection and the magnetospheric system.

Stark racial and ethnic disparities in Alzheimer’s disease (AD) and related dementias (ADRD) have been documented, largely attributable to the impact of social and structural drivers of health. The structural drivers of health include the institutions, practices, cultural norms, and policies that dictate the inequitable distribution of the social determinants of health (SDoH), defined as the conditions where people live, work, play, and age, and consist of various forms of systemic oppression including structural racism. The overlapping effects of race and place on health have been studied extensively, with an increased focus on the operationalization and measurement of “place-effects” on health through neighborhood characteristics and the built environment. Previous studies have demonstrated associations of place-based SDoH with cardiometabolic health and cognition. However, research studying the relationship of place-based SDoH with ADRD-associated neuroimaging and plasma biomarkers is still limited.

Researchers at Tohoku University have developed a method to detect dark matter by connecting quantum sensors in optimized networks, potentially solving one of physics’ greatest mysteries[^1]. The quantum network approach aims to boost sensor sensitivity to detect the faint traces dark matter may leave behind, though it cannot be directly observed[^2].
