A SYSTEM THAT AUTOMATICALLY GENERATES COMIC BOOKS FROM MOVIES AND OTHER VIDEOS
Over the past few years, computer scientists have created numerous computational techniques that can automatically generate texts, images and other types of data. These models are highly advantageous, particularly for creating data or creative works that are demanding and time-consuming for humans to produce manually.
AI MAY MISTAKE CHESS DISCUSSIONS AS RACIST TALK
“The Queen’s Gambit,” the recent TV mini-series about a chess master, may have stirred increased interest in chess, but a word to the wise: social media talk about game-piece colors could lead to misunderstandings, at least for hate-speech detection software.
RESEARCH HELPS SOLAR TECHNOLOGY BECOME MORE AFFORDABLE
Scientists at The University of Manchester have found a way to accelerate the uptake of solar technology, by increasing the environmental safety of perovskite solar cells.
Laser-cutting is an essential part of many industries, from car manufacturing to construction. However, the process isn’t always easy or efficient: Cutting huge sheets of metal requires time and expertise, and even the most careful users can still produce huge amounts of leftover material that go to waste. The underlying technologies that use lasers to cut edges aren’t actually all that cutting-edge: their users are often in the dark about how much of each material they’ve used, or if a design they have in mind can even be fabricated.
🗞 PHYSICS NEWS⚙♨:
ENGINEERS PLACE MOLECULE-SCALE DEVICES IN PRECISE ORIENTATION
Engineers have developed a technique that allows them to precisely place microscopic devices formed from folded DNA molecules in not only a specific location but also in a specific orientation.
X-RAY DOUBLE FLASHES CONTROL ATOMIC NUCLEI
A team of researchers from the Max Planck Institute for Nuclear Physics in Heidelberg has coherently controlled nuclear excitations using suitably shaped X-ray light for the first time. In the experiment performed at the European Synchrotron ESRF, they achieved a temporal control stability of a few zeptoseconds. This forms the basis for new experimental approaches exploiting the control of nuclear dynamics which could lead to more precise future time standards and open new possibilities on the way to nuclear batteries.
SLAC’s NEW X-RAY LASER DATA SYSTEM WILL PROCESS A MILLION IMAGES A SECOND
When upgrades to the X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory are complete, the powerful new machine will capture up to 1 terabyte of data per second; that’s a data rate equivalent to streaming about one thousand full-length movies in just a single second, and analyzing every frame of each movie as they zoom past in this super-fast-forward mode.
🗞 EARTH NEWS🌏:
ANCIENT RELIC POINTS TO A TURNING POINT IN EARTH’S HISTORY 42,000 YEARS AGO
The temporary breakdown of Earth’s magnetic field 42,000 years ago sparked major climate shifts that led to global environmental change and mass extinctions, a new international study co-led by UNSW Sydney and the South Australian Museum shows.
THE INTENSITY OF SUNLIGHT OVER DECADES RELATED TO ULTRA-FINE, MAN-MADE DIRT PARTICLES
Based on the long-term Potsdam radiation time series, ETH Professor Martin Wild and his collaborators have shown that variations in the intensity of sunlight over decades are down to ultra-fine, man-made dirt particles in the atmosphere.
SHALE GAS DEVELOPMENT IN PENNSYLVANIA INCREASES EXPOSURE OF SOME TO AIR POLLUTANTS
Air pollution levels may have exceeded air quality standards during the development of some Marcellus Shale natural gas wells in Pennsylvania, potentially impacting more than 36,000 people in one year alone during the drilling boom, according to Penn State scientists.
INCREASING TEMPERATURES WILL HIT MEAT AND MILK PRODUCTION IN EAST AFRICA
New research published in Nature Food warns that heat stress in animals caused by rising temperatures and humidity will occur more frequently and for longer periods, impacting milk and meat productivity for dairy cattle, beef cattle, sheep, goat, pigs and poultry across East Africa.
🗞 ASTRONOMY & SPACE NEWS🌪🎇:
FIRST BLACK HOLE EVER DETECTED IS MORE MASSIVE THAN WE THOUGHT
New observations of the first black hole ever detected have led astronomers to question what they know about the Universe’s most mysterious objects.
NASA ROVER LANDS ON MARS TO LOOK FOR SIGNS OF ANCIENT LIFE
A NASA rover streaked through the orange Martian sky and landed on the planet Thursday, accomplishing the riskiest step yet in an epic quest to bring back rocks that could answer whether life ever existed on Mars.
NASA ROVER STREAKS TOWARD A LANDING ON MARS
A NASA rover streaked toward a landing on Mars on Thursday in the riskiest step yet in an epic quest to bring back rocks that could answer whether life ever existed on the red planet.
SIGNALS IN OPTICAL BAND CAN BE USED AS PROBE TO DETECT ATMOSPHERE ESCAPE OF HOT JUPITERS
YAN Dongdong, GUO Jianheng and Xing Lei from Yunnan Observatories of the Chinese Academy of Sciences, collaborating with Huang Chenliang from University of Arizona, deduced that there is an expanding and escaping thermal neutral hydrogen atmosphere around hot Jupiter WASP-121b by simulating the optical transmission spectrum (Hα) of this exoplanet. The study was published in The Astrophysical Journal Letters.
🗞 NANOTECHNOLOGY NEWS⛄☃:
RESEARCHERS FLIP THE SWITCH TO MAKE MICROSENSORS SUPER SENSITIVE TO BIOMOLECULES
A team led by researchers at the New York University Tandon School of Engineering have found a new way of enhancing the performance of electrochemical micro-sensors. This discovery could lead to the detection of biomolecules, such as dopamine, at lower concentrations than is possible today. Their findings are described in a paper published in the journal Biosensors and Bioelectronics.
USING PERSISTENTLY LUMINESCENT NANOCRYSTALS TO CREATE 3-D X-RAYS
A team of researchers with members from China and Singapore has found that it is possible to use persistently luminescent nanocrystals to create 3-D X-rays. In their paper published in the journal Nature, the group describes a means for creating nanocrystals that can hold onto excited charge carriers, and how they used those crystals to fashion a bendable sheet that could be used to create 3-D images using X-rays. Albano Carneiro Neto and Oscar Malta, with the University of Aveiro and the Federal University of Pernambuco, respectively, have published a News & Views piece in the same journal issue outlining the history of 3-D X-ray research and the work done by the team with this new effort.
ENERGY-HARVEST TECHNOLOGY TO MAKE ROADS SAFER
Triboelectric nanogenerators (TENGs) are an emerging technology that harvests the freely available mechanical energy from daily human activities.
