Phys.org / Exposed ends and bends attract DNA-cutting enzymes, live imaging reveals
Researchers at the Nano Life Science Institute (WPI-NanoLSI) at Kanazawa University have directly visualized how enzymes find and break DNA molecules in real time. Using high-speed atomic force microscopy, the team followed ...
Dialog / Avian odysseys: Tracking raptor migrations from Europe to Africa
At the southwest tip of Sweden, the Falsterbo Peninsula stretches into the Baltic Sea, creating a natural bottleneck for hundreds of millions of birds traveling south for the winter each year. Falsterbo is particularly known ...
Phys.org / Assembly pathway reveals how bacteria build protein coils that extend in acid
The assembly pathway behind refractile-body proteins may have finally been resolved, researchers from Science Tokyo report. Using genetic engineering and several techniques for analyzing protein structure, they investigated ...
Phys.org / Mediterranean rockrose extract shows fungicidal activity against common skin infections
A polyphenol-rich extract from Cistus salviifolius, a Mediterranean rockrose species traditionally used to treat skin conditions, has shown fungicidal activity against several dermatophytes, the fungi responsible for superficial ...
Phys.org / Automated lipid nanoparticle production could accelerate the development of RNA therapies
RNA vaccines and other nucleic acid therapeutics are typically packaged within fatty molecules known as lipid nanoparticles (LNPs). MIT researchers have now developed a way to produce these particles much more quickly and ...
Phys.org / Light and electricity offer new way to control ion separation in membranes
Lithium, magnesium, potassium and many other ions usually occur together in natural and industrial solutions. Separating them from one another is a challenge, for example, in the extraction and processing of raw materials.
Phys.org / Antarctic radar data improves forecasts for Southern Hemisphere atmospheric rivers in tests
Weather forecasts in the Southern Hemisphere (SH) are generally less accurate than those in the Northern Hemisphere because Antarctica and the surrounding Southern Ocean have relatively few weather observations. With limited ...
Phys.org / Who's really No. 1? Statisticians build a better way to make sense of competing sports rankings
Who, really, is the best player in baseball? Ask five sports media outlets and you may get five different answers. Rankings can vary dramatically from one source to another, change from year to year and leave out different ...
Phys.org / Changing climate may influence risks from deadly rodent-borne diseases
Changes in rainfall can trigger increases in rodent populations and subsequent spikes in infection, new research has found, revealing how a changing climate could have consequences for human health.
Phys.org / Bullfrog brains can make their own backup fuel
For decades, scientists believed most animals relied on a steady supply of glucose, the body's primary fuel source, to power their brains. When glucose runs out, neural activity begins to fail, potentially leading to lasting ...
Phys.org / How bootmaking in Victorian England helps us think about the future of work
Put yourself in the shoes of a bootmaker in 19th-century England. Bootmaking was a sophisticated craft that involved cutting and stitching leather. It required skill, experience and time.
Phys.org / Blue-light tools let researchers track, redirect and sever cells' transport routes
Light is fundamental to human life—without it, we'd be hungry, cold and blind. But what if the same light that sustains us could also be used to control and observe parts of cells within our bodies?
