Scientific Reports, Published online: 05 May 2026; doi:10.1038/s41598-026-50633-9 Advanced methodology for damping characterization of the human tympanic membrane using high-speed digital holography and STFT analysis

Gravity, it turns out, is not simply a background condition of life. It’s more like a dial, one your nervous system is always reading, using the signal to decide whether to spend energy or save it. We know this in part because of what happened when researchers at the University of California, Riverside put fruit flies into a centrifuge and turned the dial up. Way up. At four times Earth’s normal …

MIT researchers found that chaotic laser light can transform into a precise, stable beam. This breakthrough enables much faster, high-resolution imaging of how drugs move into the brain. Researchers at MIT have identified an unexpected effect in optical physics that could lead to a new kind of bioimaging technology with both higher speed and strong [...]

Nature Physics, Published online: 30 April 2026; doi:10.1038/s41567-026-03242-2 The mechanical stability of proteins affects their import into the nucleus. Now it is shown that protein transport in and out of the nucleus depends on the local mechanostability of the protein cargo.

Across turbulence, neural networks, bioenergetics, chaos theory, and plasma physics, a recurring structural motif appears: localized coherence nodes organize global system behavior within dissipative environments. The Δ±1 framework proposes a cross-scale vocabulary for this convergence.

Physics, biomedicine, and computer networking were the dominant projects for the Expedition 74 crew aboard the International Space Station on Wednesday. The orbital residents also continued unpacking cargo from a pair of resupply ships while keeping up life support maintenance. The post Quantum Physics, Biomedicine, and Computer Gear Fill Wednesday’s Schedule appeared first on NASA Science .

Scientists have discovered how cells decide when to respond to physical forces, potentially opening new avenues for tackling diseases such as cancer and fibrosis.

The headlines focus mainly on breakthroughs in curing diseases; the infrastructure needed to enable that research gets little attention except in times of crisis

The hatches are open between the International Space Station and the new Progress 95 cargo spacecraft following the delivery of about three tons of food, fuel, and supplies on Monday. Meanwhile, physics equipment maintenance topped the scientific schedule as the lab residents installed new quantum research gear and stowed cryogenic fluid hardware. The post Crew Opens Cargo Craft, Works on Physics…

Nature Communications, Published online: 28 April 2026; doi:10.1038/s41467-026-71939-2 RNA levels control phase separation of RNA-binding proteins in cells. Here, the authors show that high RNA concentrations suppress hnRNPA1 phase separation by inducing the formation of nano-sized protein-RNA clusters in the dilute phase, which convert to amyloid fibrils more slowly than condensates.

Research Microfluidics for biology We develop and use microfluidic devices to explore questions in biology. Often this involves making picoliter to nanoliter aqueous droplets in an inert, immiscible, carrier fluid. Surfactant keeps each droplet separate from every other droplet, so we can treat each as a reaction vessel containing an independent experiment. This gives us...

Mitochondrial ultraweak photon emission (UPE) is canonically attributed to stochastic reactive oxygen species chemistry and excited carbonyl relaxation. The companion paper (Meyler, 2026a) established a formal information-theoretic framework—mutual information bounds, the data processing inequality, a seven-condition blocking protocol, and a photon-substitution arm—that converts the signaling hyp…

Research Biophysics We use our expertise and our experimental tools to investigate the properties of biological materials and to study the behavior of cells. Much of our focus is on developing an understanding of the mechanical properties of biopolymer networks, formed by reconstituting proteins into gelled networks. These include networks of actin, microtubules, intermediate filaments,...

The brain is more mechanically connected to the body than previously appreciated, scientists reported in Nature Neuroscience, noting the connection could be a potential biological mechanism underlying why exercise is thought to benefit brain health.

Hello all, I am working on a coupled hydraulic-electric model arising in nerve-membrane biophysics, in which the dynamics takes the singularly perturbed canonical form $$ \partial_t x = f(x, y; \partial_\xi), \qquad \varepsilon, \partial_t y = g(x, y), $$ with slow variable ##x = (p, q) \in...

From energy production to genetic changes: molecules are constantly in motion within biological cells. However, experimentally investigating such processes, which occur on very small length and time scales, is extremely difficult. To overcome these challenges, a research team at the Max Planck Insti...

Fluorescent proteins have revolutionized science, enabling researchers to tag and visualize individual molecules in living cells, tissues, and animals.

Supercoiling as a regulator: the role of biophysical feedback in transcription and chromatin dynamics Johnstone, Christopher P. Transcription induces a wave of DNA supercoiling, altering the binding affinity of RNA polymerases and reshaping the biochemical landscape of gene regulation. Instead of transcription being a simply biochemical progress acting over a static energy landscape, this superco…

Photonics and optical technologies provide powerful, noninvasive means to study microorganisms, including those that remain unculturable, by detecting light signals arising from specific structural and biochemical features. These include intrinsic chromophores such as aromatic amino acids, nicotinamide adenine dinucleotide hydride, and flavins; spectral signatures of functional groups in proteins…
