Tumors illuminated brightly and precisely with new biodegradable nanoprobe
To highlight tumors in the body for cancer diagnosis, doctors can use tiny optical probes (nanoprobes) that light up when they attach to tumors. These nanoprobes allow doctors to detect the location, shape and size of cancers in the body......»»
A new method to fabricate optical devices that more closely match their design specifications
Photolithography involves manipulating light to precisely etch features onto a surface, and is commonly used to fabricate computer chips and optical devices like lenses. But tiny deviations during the manufacturing process often cause these devices t.....»»
Translating humorous children"s poetry? Content matters most
Translating poetry is notoriously difficult. Translating poetry in such a way that the humorous nature of a poem remains intact is even more difficult, even though it is precisely jokes that can encourage children to read more, notes Ph.D. candidate.....»»
A nanoprobe with a barcode: Sensors detect active proteases
Protein-splitting enzymes play an important role in many physiological processes. Such proteases are generally present in an inactive state, only becoming activated under certain conditions. Some are linked to diseases like infections or cancer, maki.....»»
Catalyst makes drugs inside the body to minimize side effects
A highly active catalyst capable of synthesizing drug molecules within the body has been developed by RIKEN chemists. In mice, an anticancer drug assembled near tumors using the injected catalyst suppressed tumor growth......»»
Creating 3D-printed materials that shrink more precisely
From houses to hearing aids, three-dimensional (3D) printing is revolutionizing how we create complex structures at scale. Zooming down to the micro and nano levels, a process known as two-photon polymerization lithography (TPL) allows scientists and.....»»
Scientists discover rare six-planet system that moves in strange synchrony
Scientists have discovered a rare sight in a nearby star system: Six planets orbiting their central star in a rhythmic beat. The planets move in an orbital waltz that repeats itself so precisely that it can be readily set to music......»»
Water and electricity: Charge effects can influence flowing droplets
From precise inkjet printing to clear vision through spectacle lenses—the influence of droplets and their movement shapes numerous areas of our daily lives. While droplets should remain precisely in place on inkjet prints, it is desirable that they.....»»
Slippery toilet bowl treatment causes bacteria to slide right off
When entering public restrooms, it's hard not to dwell on what germs previous users have left behind in the toilet bowl. Imagine, instead, a self-cleaning system that doesn't require a brightly colored gel. Researchers reporting in ACS Applied Materi.....»»
Silk lines help pirate spiders trick, capture eight-legged prey
Headlamps alone illuminated the trail bisecting the Costa Rican rainforest. Having waded the black of the Tirimbina reserve so often before, Gilbert Barrantes, Laura Segura Hernández and Diego Solano Brenes knew the routine......»»
3D printing precisely: Low-cost error compensation for fabrication of high-precision microstructures
In today's fast-paced technological landscape, the proverb "the bigger the better" was turned upside down and a race to make everything smaller has started. From miniature optical components to micro-scale medical devices, the quest for creating ever.....»»

Apple hikes Apple One cost by up to $5 as most services prices rise
Apple has raised the prices of many of its services subscriptions, from individual ones such as Apple Music, to its overall Apple One bundle tiers.Apple has increased the cost of subscribing to some of its services almost precisely 12 months after it.....»»
Researchers propose new strategy to improve efficiency for nanotherapeutic delivery in tumors
A team led by Prof. Wang Yucai and Associate Prof. Jiang Wei from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) revealed the mechanism of the tumor vascular basement membranes (BM) blocking nanopart.....»»
Miniature magnetic resonance imager made of diamond
The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now, the resolution of conventional imaging methods has not been high enough to r.....»»
Research shows biodegradable plastics are still harmful to fish
Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a University of Otago study showing they are still harmful to fish......»»
New map of space precisely measures nearly 400,000 nearby galaxies
Astronomers have created a detailed atlas of almost 400,000 galaxies in our cosmic neighborhood. The Siena Galaxy Atlas was compiled using data from NSF's NOIRLab telescopes, and is designed to be the preeminent digital galaxy atlas for large galaxie.....»»
UK"s latest embarrassing technology demand centers on phone thefts
The UK has had the bright idea that Apple and others should design a way to stop cellphone thefts — by doing precisely what they've already been doing for years.Find My on iPhonesThere are children starving in the UK, school and theater buildings a.....»»
Sustainable smart agriculture with a biodegradable soil moisture sensor
Increasingly limited land and water resources have inspired the development of precision agriculture, which is the use of remote sensing technology to monitor air and soil environmental data in real time to help optimize crop output. Maximizing the s.....»»
Interplay of free electrons: Tailored electron pulses for improved electron microscopy
Electron microscopes provide unique vistas of nanoscale structures, but their resolution is limited by the mutual repulsion of electrons. Researchers in Göttingen have now succeeded in precisely measuring the influence of these interactions. They di.....»»
Researchers develop tiny nanoSABERs to aid battle against cancer
When Jedi Knights need to vanquish an enemy, they whip out their trusty lightsabers. In the future, thanks to Johns Hopkins researchers, doctors seeking to crush cancer may wield minuscule molecular nanoSABERs that allow them to look at tumors in way.....»»
