Published An innovative twist on quantum bits: Tubular nanomaterial of carbon makes ideal home for spinning quantum bits
(via sciencedaily.com) Scientists develop method for chemically modifying nanoscale tubes of carbon atoms, so they can host spinning electrons to serve as stable quantum bits in quantum technologies.
Published A mixture of trees purifies urban air best
(via sciencedaily.com) Conifers are generally better than broad-leafed trees at purifying air from pollutants. A new study shows that the best trees for air purification depend on the type of pollutant involved.
Published Bending 2D nanomaterial could 'switch on' future technologies
(via sciencedaily.com) Materials scientists have uncovered a property of ferroelectric 2D materials that could be exploited in future devices.
Published Phone-based measurements provide fast, accurate information about the health of forests
(via sciencedaily.com) Researchers have developed an algorithm that uses computer vision techniques to accurately measure trees almost five times faster than traditional, manual methods.
Published Scientists use satellites to track earth 'greening' amid climate change
(via sciencedaily.com) Researchers found changes in 'greening,' or the amount of leaves plants are able to produce, will play a significant role in how much carbon dioxide plants capture and store.
Published Scientists develop novel approach to enhance drug delivery for brain tumors in children
(via sciencedaily.com) Researchers have developed a new drug delivery approach that uses nanoparticles to enable more effective and targeted delivery of anti-cancer drugs to treat brain tumors in children.
Published Earlier take-off could lead to fewer bumblebees and less pollination
(via sciencedaily.com) With the arrival of spring, bumblebee queens take their first wing beat of the season and set out to find new nesting sites. But they are flying earlier in the year, as a result of a warmer climate and a changing agricultural landscape, according to new research.
Published Mulching time of forest meadows influences insect diversity
(via sciencedaily.com) Researchers have examined how mulching at different times affects insect flower-visitors and larvae.
Published Deforestation in the tropics linked to a reduction in rainfall
(via sciencedaily.com) Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now, scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.
Published The counting of nine billion trees could help manage climate credits and nature restoration
(via sciencedaily.com) Researchers have developed a method that has now mapped several billion trees and their carbon uptake in Africa's Sahel. In the future, the method could be used to monitor whether climate credit purchases have a positive effect on the number of trees and whether nature restoration is working.
Published New purification method could make protein drugs cheaper
(via sciencedaily.com) Original source Engineers devised a way to purify protein drugs during manufacturing. Their approach, which uses nanoparticles to rapidly crystallize proteins, could help make protein drugs more affordable and accessible, especially in developing countries.
Published A motion freezer for many particles
(via sciencedaily.com) From the way that particles scatter light, it is possible to calculate a special light field that can slow these particles down. This is a new and powerful method to cool particles down to extremely low temperatures.
Published Flower power: The role of ants in forest regeneration
(via sciencedaily.com) Ants play a key role in forest regeneration, according to a new article.
Published Tiny new climbing robot was inspired by geckos and inchworms
(via sciencedaily.com) A tiny robot that could one day help doctors perform surgery was inspired by the incredible gripping ability of geckos and the efficient locomotion of inchworms.
Published Chaos on the nanometer scale
(via sciencedaily.com) Chaotic behavior is typically known from large systems: for example, from weather, from asteroids in space that are simultaneously attracted by several large celestial bodies, or from swinging pendulums that are coupled together. On the atomic scale, however, one does normally not encounter chaos -- other effects predominate. Now scientists have been able to detect clear indications of chaos on the nanometer scale -- in chemical reactions on tiny rhodium crystals.
Published The rediscovery of an ethereal fairy lantern brightly illuminates their mysterious past
(via sciencedaily.com) After more than 30 years, botanists have rediscovered Thismia kobensis, a type of mysterious-looking rare plant commonly referred to as 'fairy lanterns'. Thismia kobensis was presumed extinct and the surprise rediscovery of this Japanese variety has illuminated hidden aspects of fairy lanterns that have puzzled and fascinated botanists for centuries.
Published Fastest laser camera films combustion in real time
(via sciencedaily.com) A research team has developed one of the world's fastest single-shot laser cameras, which is at least a thousand times faster than today's most modern equipment for combustion diagnostics. The discovery has enormous significance for studying the lightning-fast combustion of hydrocarbons.
Published Insect bite marks show first fossil evidence for plants' leaves folding up at night
(via sciencedaily.com) Plants can move in ways that might surprise you. Some of them even show 'sleep movements,' folding or raising their leaves each night before opening them again the next day. Now, researchers offer convincing evidence for these nightly movements, also known as foliar nyctinasty, in fossil plants that lived more than 250 million years ago.
Published Scientists unlock key to drought-resistant wheat plants with longer roots
(via sciencedaily.com) Growing wheat in drought conditions may be easier in the future. Researchers found the right number of copies of a specific group of genes can stimulate longer root growth, enabling wheat plants to pull water from deeper supplies.
Published Heterostructures support predictions of counterpropagating charged edge modes at the v=2/3 fractional quantum Hall state
(via sciencedaily.com) Original source Researchers have tested models of edge conduction with a device built on top of the semiconductor heterostructure which consists of gold gates that come close together. Voltage is applied on the gates to direct the edge states through the middle of the point contact, where they are close enough that quantum tunneling can occur between the edge states on opposite sides the sample. Changes in the electrical current flowing through the device are used to test the theorists' predictions.
