Understanding how these aerosols disperse in the air is crucial for minimizing the transmission of pathogens in indoor spaces, but their dynamics are complex and depend on many factors: the force of the exhalation, the morphology of the respiratory system, the characteristics of the space, etc. Now, a new study led by researchers from the Universitat Rovira i Virgili has shown that temperature also plays an important role. https://phys.org/news/2026-06-temperature-gaps-clouds-stay-denser.html Soft Matter Wed, 03 Jun 2026 17:30:02 EDT news699722042 Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past decades, due to their unique and intriguing properties. Einstein's theory of general relativity predicts that black holes obey a set of rules, known as the laws of black hole mechanics. These rules somewhat resemble the laws of thermodynamics, which delineate how energy, heat, and entropy behave in our universe. https://phys.org/news/2026-06-violating-3rd-law-black-hole.html General Physics Wed, 03 Jun 2026 07:00:04 EDT news699524996 Embryonic development is one of the most dynamic biological processes in nature.

Researchers have used two techniques—high-speed temperature mapping and artificial heating—to observe how heat dissipates from living cells and similar-sized artificial, fluid-filled sacs (liposomes). While heat dispersed quickly from the artificial liposomes as expected, cells cooled significantly more slowly due to other biomolecules within the cell. https://phys.org/news/2026-05-cells-ways-standard-fluid-physics.html Cell & Microbiology Thu, 28 May 2026 05:00:03 EDT news699117362 For more than half a century, materials scientists have struggled with how to simulate the complexity of polymer materials. An individual chain can comprise tens of thousands of atoms, a melt or composite contains billions, and the properties engineers actually care about, such as how an adhesive grips a surface, how a self-assembling block copolymer locks into a nanostructure, or how a biopolymer film stretches without tearing, emerge only over length and time scales that forcible atomistic simulation cannot reach. https://phys.org/news/2026-05-thermodynamic-laws-ai-polymer.html Polymers Tue, 26 May 2026 19:20:07 EDT news699029450 When it comes to technology and innovation, we have a lot to thank Mother Nature for. Learning from the natural world has led to a range of useful products, including Velcro, self-cleaning paint, and ultra-strong body armor.

These results provide a fluid-dynamical explanation of the functional value of the flutter kick. https://phys.org/news/2026-05-visualizing-flutter-vertical-vortices-generate.html Soft Matter Mon, 25 May 2026 13:40:02 EDT news698932622 When we think about highly sensitive medical testing, we often imagine a hospital laboratory filled with large instruments, trained technicians, and carefully controlled conditions. This is especially true for optical biosensing, where scientists try to detect extremely small changes caused by biomolecules binding to a sensor surface. https://phys.org/news/2026-05-based-sensor-ultrasensitive-disease-portable.html Optics & Photonics Thu, 21 May 2026 17:40:01 EDT news698499656 Controlling heat flow is a major challenge for many technologies.

For example, 2D semiconductors are expected to be used in conduction channels of future transistors. However, their thermal behavior remains difficult to predict and control. https://phys.org/news/2026-05-honey-regime-ultrathin-semiconductors.html Nanophysics Fri, 15 May 2026 09:20:01 EDT news698054064 Can "snow" fall in the ocean and influence the climate of the entire planet?

Researchers at the Karlsruhe Institute of Technology (KIT) have developed a new laser-based technique that allows microscopic samples such as cells to be rotated contact-free in all three spatial directions. The laser creates tiny temperature differences in the liquid, which trigger gentle fluid flows that move the sample. This protects delicate samples and enables more accurate three-dimensional images—an important step for basic medical research. https://phys.org/news/2026-05-gentle-laser-driven-enable-precise.html Cell & Microbiology Tue, 12 May 2026 14:40:04 EDT news697807441 Researchers from the National University of Singapore (NUS) have discovered that cancer cells do not simply push through surrounding tissues to spread, but instead actively grip onto protective tissue barriers and pull them apart, revealing a fundamentally new mechanism of cancer invasion that could open fresh avenues for therapeutic intervention. https://phys.org/news/2026-05-invading-cancer-cells-rip-tissues.html Cell & Microbiology Tue, 12 May 2026 14:00:02 EDT news697803601 Researchers at Worcester Polytechnic Institute (WPI) have developed a solid polymer coated with harmless viruses to detect the bacteria Salmonella enterica (S. enterica), an advance that could lead to new ways of finding contamination in the food supply.
