Research shows that by creating steep tolls for cars to enter Manhattan, traffic congestion and greenhouse gas emissions could be reduced.
Toronto's Collision tech conference with 30,000 attendees goes online-only on COVID-19 fears
Organizers of the Collision conference say they are cancelling the in-person component this year amid concerns around a novel form of coronavirus.
Letter from 'Winnie the Pooh' to young fan fetches more than $15,000
A 1935 letter signed by "Winnie the Pooh" -- actually written by illustrator Ernest Howard Shepard -- fetched triple its expected amount when it sold for more than $15,000.
Man finds Haitian 'Phoenix Button' from 1800s on Washington state beach
A Washington state man using his metal detector on a beach made an unusual discovery -- a Haitian "Phoenix Button" from the 1800s.
Why are plants green?
When sunlight shining on a leaf changes rapidly, plants must protect themselves from the ensuing sudden surges of solar energy. To cope with these changes, photosynthetic organisms have developed numerous...
X-rays size up protein structure at the 'heart' of COVID-19 virus
A team of researchers at the Department of Energy's Oak Ridge and Argonne national laboratories has performed the first room-temperature X-ray measurements on the SARS-CoV-2 main protease—the enzyme that enables...
Researchers discover new boron-lanthanide nanostructure
The discovery of carbon nanostructures like two-dimensional graphene and soccer ball-shaped buckyballs helped to launch a nanotechnology revolution. In recent years, researchers from Brown University and elsewhere have shown that...
Researchers develop method for producing precision diffraction gratings
Researchers at ETH Zurich have developed a method for the production of wavy surfaces with nanometer precision. In the future this method could be used, for instance, to make optical...
Bluetooth speakers that will rock your world
Impeccable portable speaker choices. (Amazon/)The fantasy of Bluetooth speakers goes something like this: You stroll into a quiet back yard party, just your phone and small speaker in your pocket. You swagger up...
Treasury places sanctions on Iran's metal industry
The U.S. Treasury Department said Thursday it would place sanctions on one domestic and four foreign subsidiaries of Iran's largest steel manufacturer.
Chemists achieve breakthrough in the synthesis of graphene nanoribbons
Graphene nanoribbons might soon be much easier to produce. An international research team led by Martin Luther University Halle-Wittenberg (MLU), the University of Tennessee and Oak Ridge National Laboratory in...
Researchers unveil mechanism to obtain metal 'nanoscrews'
Led by the Ikerbasque professor Luis Liz-Marzán, researchers at the Centre for Cooperative Research in Biomaterials CIC biomaGUNE have developed a mechanism by which gold atoms are deposited by means...
Why are plants green? Research team's model reproduces photosynthesis
When sunlight shining on a leaf changes rapidly, plants must protect themselves from the ensuing sudden surges of solar energy. To cope with these changes, photosynthetic organisms—from plants to bacteria—have...
Michael Shannon, Kate Hudson set for comedy film 'Shriver'
Michael Shannon, Kate Hudson, Don Johnson and Da'Vine Joy Randolph are set to star in upcoming comedy film "Shriver," based on the novel of the same name by author Chris...
Quieting a noisy antenna reproduces photosynthetic light-harvesting spectra
Photosynthesis achieves near unity light-harvesting quantum efficiency yet it remains unknown whether there exists a fundamental organizing principle giving rise to robust light harvesting in the presence of dynamic light...
Metalens-array-based high-dimensional and multiphoton quantum source
The development of two-dimensional metasurfaces has shown great potential in quantum-optical technologies because of the excellent flexibility in light-field manipulation. By integrating a metalens array with a nonlinear crystal, we...
Micelle-directed chiral seeded growth on anisotropic gold nanocrystals
Surfactant-assisted seeded growth of metal nanoparticles (NPs) can be engineered to produce anisotropic gold nanocrystals with high chiroptical activity through the templating effect of chiral micelles formed in the presence...
Mass-resolved electronic circular dichroism ion spectroscopy
DNA and proteins are chiral: Their three-dimensional structures cannot be superimposed with their mirror images. Circular dichroism spectroscopy is widely used to characterize chiral compounds, but data interpretation is difficult...
New radar allows cars to spot hazards around corners
Using radar commonly deployed to track speeders and fastballs, researchers have developed an automated system that will allow cars to peer around corners and spot oncoming traffic and pedestrians. The...
