REALITYSKETCH: AN AR INTERFACE TO CREATE RESPONSIVE SKETCHES
Researchers at University of Calgary, Adobe Research and University of Colorado Boulder have recently created an augmented reality (AR) interface that can be used to produce responsive sketches, graphics and visualizations. Their work, initially pre-published on arXiv, won the Best Paper Honorable Mention and Best Demo Honorable Mention awards at the ACM Symposium on User Interface Software and Technology (UIST’20).
NEUROSCIENTISTS FIND A WAY TO MAKE OBJECT-RECOGNITION MODELS PERFORM BETTER
Computer vision models known as convolutional neural networks can be trained to recognize objects nearly as accurately as humans do. However, these models have one significant flaw: Very small changes to an image, which would be nearly imperceptible to a human viewer, can trick them into making egregious errors such as classifying a cat as a tree.
LOON BALLOONS GET BOOST FROM GOOGLE AI
Google’s AI future is up in the air.
🗞 PHYSICS NEWS⚙♨:
SEARCHING FOR SUB-EV STERILE NEUTRINOS USING TWO HIGHLY SENSITIVE DETECTORS
The standard model of particle physics only accounts for 20% of matter in the universe. Physicists have theorized that the remaining 80% is made up by so-called dark matter, which consists of particles that do not emit, absorb or reflect light and thus cannot be directly observed using any existing instruments.
PHYSICISTS CAPTURE THE SOUND OF A ‘PERFECT’ FLUID
For some, the sound of a “perfect flow” might be the gentle lapping of a forest brook or perhaps the tinkling of water poured from a pitcher. For physicists, a perfect flow is more specific, referring to a fluid that flows with the smallest amount of friction, or viscosity, allowed by the laws of quantum mechanics. Such perfectly fluid behavior is rare in nature, but it is thought to occur in the cores of neutron stars and in the soupy plasma of the early universe.
MAPPING QUANTUM STRUCTURES WITH LIGHT TO UNLOCK THEIR CAPABILITIES
A new tool that uses light to map out the electronic structures of crystals could reveal the capabilities of emerging quantum materials and pave the way for advanced energy technologies and quantum computers, according to researchers at the University of Michigan, University of Regensburg and University of Marburg.
🗞 EARTH NEWS🌏:
SHUTTERING FOSSIL FUEL POWER PLANTS MAY COST LESS THAN EXPECTED
Decarbonizing U.S. electricity production will require both construction of renewable energy sources and retirement of power plants now operated by fossil fuels. A generator-level model described in the December 4 issue of the journal Science suggests that most fossil fuel power plants could complete normal lifespans and still close by 2035 because so many facilities are nearing the end of their operational lives.
ONCE IN A LIFETIME FLOODS TO BECOME REGULAR OCCURRENCES BY END OF CENTURY
Superstorm Sandy brought flood-levels to the New York region that had not been seen in generations. Causing an estimated $74.1 billion in damages, it was the fourth-costliest U.S. storm behind Hurricane Katrina in 2005 and hurricanes Harvey and Maria in 2017 according to the National Oceanic and Atmospheric Administration. Now, due to the impact of climate change, researchers at Stevens Institute of Technology have found that 100-year and 500-year flood levels could become regular occurrences for the thousands of homes surrounding Jamaica Bay, New York by the end of the century.
IS ARCTIC WARMING BEHIND A MONSTER SAHARAN DUST STORM?
The Sahara Desert is the world’s biggest source of dust and in 2020, it broke the June record for sending the largest and thickest dust cloud toward the Americas.
🗞 ASTRONOMY & SPACE NEWS🌪🎇:
A THREE-DIMENSIONAL VIEW OF THE MILKY WAY
In our Milky Way, there are about 200 billion suns as well as large quantities of gas, some of which serves as raw material for star births. The gas collects in compact lumps but also appears as extended molecular clouds. Astronomers have used the Apex sub-millimeter telescope in Chile to look deep into the galactic plane and measure the interstellar medium. They studied the distribution of the cold molecular gas in the inner region of the Milky Way with unprecedented accuracy. The researchers cataloged more than 10,000 interstellar clouds. They found out that currently only about 10% of them contain stars. The project is called SEDIGISM (Structure, Excitation and Dynamics of the Inner Galactic Interstellar Medium) and covers an area of 84 square degrees in the southern sky.
120,000-YEAR-OLD SUPERNOVA REMNANTS DETECTED IN NEIGHBORING GALAXY
Western Sydney University researchers have discovered the ‘senior citizens’ of our neighboring galaxy—close to 120,000-year-old remains of exploding stars known as supernova remnants.
CHINESE SPACECRAFT CARRYING LUNAR ROCKS LIFTS OFF FROM MOON
A Chinese spacecraft lifted off from the moon Thursday night with a load of lunar rocks, the first stage of its return to Earth, the government space agency reported.
🗞 NANOTECHNOLOGY NEWS⛄☃:
MEDICINE-CARRIERS MADE FROM HUMAN CELLS CAN CURE LUNG INFECTIONS
Scientists used human white blood cell membranes to carry two drugs, an antibiotic and an anti-inflammatory, directly to infected lungs in mice.
COOLING ELECTRONICS EFFICIENTLY WITH GRAPHENE-ENHANCED HEAT PIPES
Researchers at Chalmers University of Technology, Sweden, have found that graphene-based heat pipes can help solve the problems of cooling electronics and power systems used in avionics, data centers and other power electronics.
PHYSICISTS DESCRIBE A NEW TYPE OF AMORPHOUS SOLID BODIES
Many substances with different chemical and physical properties, from diamonds to graphite, are made up of carbon atoms. Amorphous forms of solid carbon do not have a fixed crystal structure and consist of structural units—nanosized graphene particles. A team of physicists from RUDN University studied the structure of amorphous carbon and suggested classifying it as a separate type of amorphous solid bodies: a molecular amorphic with enforced fragmentation. The results of the study were published in the Fullerenes, Nanotubes and Carbon Nanostructures journal.
