Published Super-sized nanocage could deliver bigger drug cargoes



Nanocages are tiny artificial containers that can be used to deliver therapeutics to a target destination in the body. But some drug molecules are like gifts that are too big for a standard-sized nanocage 'box'. Now researchers describe how they have built a super-sized nanocage that could be used to deliver larger drug cargoes. They have built a bigger box.
Published Researchers use 21st century methods to record 2,000 years of ancient graffiti in Egypt


Researchers are learning more about ancient graffiti -- and their intriguing comparisons to modern graffiti -- as they produce a state-of-the-art 3D recording of the Temple of Isis in Philae, Egypt.
Published Ancient DNA reveals Asian ancestry introduced to East Africa in early modern times


The largest-yet analysis of ancient DNA in Africa, which includes the first ancient DNA recovered from members of the medieval Swahili civilization, has now broken the stalemate about the extent to which people from outside Africa contributed to Swahili culture and ancestry.
Published Revolutionary battery technology to boost EV range 10-fold or more


A team develops layering-charged, polymer-based stable high-capacity anode material.
Published Highly charged ions melt nano gold nuggets



Shooting ions is very different from shooting a gun: By firing highly charged ions onto tiny gold structures, these structures can be modified in technologically interesting ways. Surprisingly, the key is not the force of impact, but the electric charge of the projectiles.
Published Biomolecules: Trying nanometer measurement for size



As part of a comparative international study, researchers have successfully tested and validated a method of investigating dynamic protein structures.
Published Probe where the protons go to develop better fuel cells



Researchers have uncovered the chemical inner-workings of an electrolyte they developed for a new generation of solid oxide fuel cells. To uncover the location of the proton-introduction reaction, the team studied extensively the hydration reaction of their scandium-substituted barium zirconate perovskite through a combination of synchrotron radiation analysis, large-scale simulations, machine learning, and thermogravimetric analysis. The new data has the potential to accelerate the development of more efficient fuel cells.
Published Nanophysics: The right twist


Stacked layers of ultrathin semiconductor materials feature phenomena that can be exploited for novel applications. Physicists have studied effects that emerge by giving two layers a slight twist.
Published Ancient genomes reveal immunity adaptation in early farmers


Research has revealed that diversity in genes coding for immunity may have facilitated adaptation to farming lifestyles in prehistoric periods.
Published Semiconductor lattice marries electrons and magnetic moments


A model system created by stacking a pair of monolayer semiconductors is giving physicists a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.
Published Ultra-lightweight multifunctional space skin created to withstand extreme conditions in space


A new nano-barrier coating could help protect ultra-lightweight carbon composite materials from extreme conditions in space, according to a new study.
Published Batteries: Passivation layer mystery solved


In our daily lives, lithium-ion batteries have become indispensable. They function only because of a passivation layer that forms during their initial cycle. As researchers found out via simulations, this solid electrolyte interphase develops not directly at the electrode but aggregates in the solution. Their findings allow the optimization of the performance and lifetime of future batteries.
Published 'Inkable' nanomaterial promises big benefits for bendable electronics


An international team of scientists is developing an inkable nanomaterial that they say could one day become a spray-on electronic component for ultra-thin, lightweight and bendable displays and devices.
Published 'Fishing' for biomarkers


Researchers have devised a tiny, nano-sized sensor capable of detecting protein biomarkers in a sample at single-molecule precision. Fittingly coined as 'hook and bait,' a tiny protein binder fuses to a small hole created in the membrane of a cell -- known as a nanopore -- which allows ionic solution to flow through it. When the sensor recognizes a targeted molecule, the ionic flow changes. This change in flow serves as the signal from the sensor that the biomarker has been found.
Published Nanotechnology could treat lymphedema


When lymphatic vessels fail, typically their ability to pump out the fluid is compromised. Researchers have now developed a new treatment using nanoparticles that can repair lymphatic vessel pumping. Traditionally, researchers in the field have tried to regrow lymphatic vessels, but repairing the pumping action is a unique approach.
Published Mind-control robots a reality?


Researchers have developed biosensor technology that will allow you to operate devices, such as robots and machines, solely through thought control.
Published Cyprus's copper deposits created one of the most important trade hubs in the Bronze Age


The coveted metal copper and a sheltered location turned the Cypriot village of Hala Sultan Tekke into one of the most important trade hubs of the Late Bronze Age. Recent excavations confirm the importance of the Bronze Age city in the first period of international trade in the Mediterranean.
Published Major advance in super-resolution fluorescence microscopy


Pushing the MINFLUX technique to higher spatial and temporal precision allows protein dynamics to be observed under physiological conditions.
Published Indigenous Ashaninka DNA helps geneticists write new chapters of pre-colonial history in South America


Geneticists have written new chapters in the reconstruction of pre-colonial Americas history after using DNA from the indigenous Ashaninka people from Amazonian Peru. They have discovered previously unexpected levels of genetic variation in this group and uncovered a strong hint that these people were involved in a South-to-North migration that led to the transition from an archaic to ceramic culture in the Caribbean islands.
Published Uncovering the ritual past of an ancient stone monument in Saudi Arabia


A comprehensive analysis of an archaeological site in Saudi Arabia sheds new light on mustatils -- stone monuments from the Late Neolithic period thought to have been used for ritual purposes.
