Probing binary stars in the Small Magellanic Cloud with the JWST

Astronomers used the JWST to study binary stars in the Small Magellanic Cloud. Maria Legnardi led the research published in Astronomy & Astrophysics. The team said, "The stellar initial mass function and the fraction of binary systems are fundamental ingredients that govern the formation and evolution of galaxies." This helps science.

New report highlights health of the UK's plankton communities

Researchers from the University of Plymouth led a new report on how climate change impacts marine plankton in UK waters. The study showed large-scale shifts in these communities. Lead author Dr Matthew Holland said, "Plankton form the foundation of marine food webs, supporting fisheries and playing a fundamental role."

Your dental fillings might be 'weaker' than you think—here is how new liquids change your smile’s durability.

A study evaluated how modeling liquids and glycerin affect the surface roughness and microhardness of one-shade resin composites. Researchers found that polishing after using modeling liquid gave the best results. However, using glycerin without mechanical finishing caused significant surface damage. The application protocol matters more than the material type used.

CortexNet: convolutional neural networks for alzheimer’s disease diagnosis using brain MRI

Researchers designed CortexNet, a new convolutional neural network, to help diagnose Alzheimer’s disease using brain MRI scans. The model showed high accuracy across different classification tests, reaching up to 98.91% performance. This lightweight architecture uses fewer resources, making it a useful tool for medical systems in areas with limited technology.

Unfrozen even at -50°C: Meet Don Juan, the 'stubborn' pond in Antarctica that refuses to freeze

Don Juan Pond in Antarctica’s McMurdo Dry Valleys stays liquid even at minus 50°C. Scientists said the pond is the saltiest natural body of water on Earth. Its high calcium chloride levels act as a super antifreeze. This unique chemistry helps the shallow pool resist freezing when temperatures drop very low.

NASA's Curiosity Rover Finds Vast Honeycomb-Like Landscape On Mars

NASA’s Curiosity rover captured a vast honeycomb-like landscape on Mars. During June 19 and 20, the rover found polygonal fractures measuring 1.5 to 3 inches across in Valle Grande. These patterns wrap around a 20-foot butte called Miraflores. Scientists said several processes can contribute to such honeycomb textures on Mars.

Seven weather systems now steer India's monsoon, and floods, heavy rain to follow soon

Seven weather systems are currently steering India’s monsoon, causing heavy rain and floods. The India Meteorological Department said the Somali Jet and a deep depression are working together like gears in a machine. This rare convergence started after a system moved over the West Bengal and Odisha coasts on July 27.

NASA's Telescope Captures Rare Orphan Black Hole Shredding A Star

NASA observed a rare black hole tearing apart a star far from a galaxy's centre. First identified in November 2025, the event showed a black hole with a mass one million times that of the Sun. Robert Stein said, "This discovery validates a new technique that can now be used."

Nano-Printed Scaffolds Bring Direct Molecular Access to Quantum Photonics

A study published in Nature Communications on Jul 30 2026 introduced Photonic Scaffolds, a new 3D-nanoprinted waveguide. This structure uses an air-dominated geometry to allow rapid molecular access while keeping light loss low. Researchers said it "could support applications in quantum memories, chemical sensing, and biological sensing" for future photonic circuits.

Uncovering the structure of the poxvirus 'portal complex'

Scientists at the Crick used cryo-electron tomography to uncover the structure of the poxvirus portal complex. Researchers identified three crucial proteins that form this molecular exit tunnel. "We identified three crucial proteins that make up the portal complex," said Miguel Hernandez Gonzalez. This discovery helps explain how viruses release genetic material.

Scientists have found a new way molecules can cooperate at room temperature

Researchers found that molecules inside tiny gold nanostructures can synchronize at room temperature. Lead author Dr. Rakesh Arul said, "What emerged was a synchronized dipole state where many molecules oscillate together." This discovery challenges old ideas about light and helps scientists build better sensors and new quantum technology devices.

Female birds have shorter lifespans than male birds across 35 North American species, researchers find

UCLA researchers found female birds have shorter lifespans than males across 35 North American species. After analyzing half a million records over 27 years, the study showed female survival rates were 12.4% lower. "Female birds, in general, are understudied relative to males, so that's what I wanted to research," said Joanna Wu.
