SN4KE: A LIGHTWEIGHT AND SCALABLE FRAMEWORK FOR BINARY MUTATION TESTING
When developers deliver software to their clients, they often also provide what is known as a ‘test suite.’ A test suite is a tool that allows users to test software, unveil any bugs it might have and give developers a chance to fix these bugs or other potential issues.
IN A LEAP FOR BATTERY RESEARCH, MACHINE LEARNING GETS SCIENTIFIC SMARTS
Scientists have taken a major step forward in harnessing machine learning to accelerate the design for better batteries: Instead of using it just to speed up scientific analysis by looking for patterns in data, as researchers generally do, they combined it with knowledge gained from experiments and equations guided by physics to discover and explain a process that shortens the lifetimes of fast-charging lithium-ion batteries.
ALGORITHM HELPS ARTIFICIAL INTELLIGENCE SYSTEMS DODGE ‘ADVERSARIAL’ INPUTS
In a perfect world, what you see is what you get. If this were the case, the job of artificial intelligence systems would be refreshingly straightforward.

DO PHOTOSYNTHETIC COMPLEXES USE QUANTUM COHERENCE TO INCREASE THEIR EFFICIENCY?
In a new report now published on Science Advances, Elinor Zerah Harush and Yonatan Dubi in the departments of chemistry and nanoscale science and technology, at the Ben-Gurion University of the Negev, Israel, discussed a direct evaluation of the effects of quantum coherence on the efficiency of three natural photosynthetic complexes. The open quantum systems approach allowed the researchers to simultaneously identify the quantum-nature and efficiency under natural physiological conditions. These systems resided in a mixed quantum-classical regime, which they characterized using dephasing-assisted transport. The efficiency was minimal at best therefore the presence of quantum coherence did not play a substantial role in the process. The efficiency was also independent of any structural parameters, suggesting the role of evolution during structural design for other uses.
NEW METHOD COULD DEMOCRATIZE DEEP LEARNING-ENHANCED MICROSCOPY
Deep learning is a potential tool for scientists to glean more detail from low-resolution images in microscopy, but it’s often difficult to gather enough baseline data to train computers in the process. Now, a new method developed by scientists at the Salk Institute could make the technology more accessible—by taking high-resolution images, and artificially degrading them.
‘MAGIC SAND’ MIGHT HELP US UNDERSTAND THE PHYSICS OF GRANULAR MATTER
Sand is a fascinating material. It can flow and be poured like a liquid, but retains many of the properties of solids, clogging pipes or forming sand dunes. The behavior of collections of small particles like sand is known as granular physics, and is an immensely important field for the handling and transport of the wide range of granular materials out there like grains, rice, powders and the vast amounts of sand used in the construction industry.

ECONOMIC BENEFITS OF PROTECTING NATURE NOW OUTWEIGH THOSE OF EXPLOITING IT, GLOBAL DATA REVEAL
The economic benefits of conserving or restoring natural sites “outweigh” the profit potential of converting them for intensive human use, according to the largest-ever study comparing the value of protecting nature at particular locations with that of exploiting it.
INSATIABLE DEMAND FOR CANNABIS HAS CREATED A GIANT CARBON FOOTPRINT
It’s no secret that the United States’ $13 billion cannabis industry is big business. Less obvious to many is the environmental toll this booming business is taking, in the form of greenhouse gas emissions from commercial, mostly indoor production.
LEGUME TREES KEY TO SUPPORTING TROPICAL FOREST GROWTH
Researchers have found that nitrogen-fixing legume trees can support themselves and surrounding trees not only with increased access to nitrogen, but with other key nutrients through enhanced mineral weathering.

A GIANT, SIZZLING PLANET MAY BE ORBITING THE STAR VEGA
Astronomers have discovered new hints of a giant, scorching-hot planet orbiting Vega, one of the brightest stars in the night sky.
NASA’S NEW MARS ROVER HITS DUSTY RED ROAD, 1ST TRIP 21 FEET
NASA’s newest Mars rover hit the dusty red road this week, putting 21 feet on the odometer in its first test drive.
MOST DISTANT QUASAR WITH POWERFUL RADIO JETS DISCOVERED
With the help of the European Southern Observatory’s Very Large Telescope (ESO’s VLT), astronomers have discovered and studied in detail the most distant source of radio emission known to date. The source is a “radio-loud” quasar—a bright object with powerful jets emitting at radio wavelengths—that is so far away its light has taken 13 billion years to reach us. The discovery could provide important clues to help astronomers understand the early Universe.

CHEAP, NONTOXIC CARBON NANODOTS POISED TO BE QUANTUM DOTS OF THE FUTURE
Tiny fluorescent semiconductor dots, called quantum dots, are useful in a variety of health and electronic technologies but are made of toxic, expensive metals. Nontoxic and economic carbon-based dots are easy to produce, but they emit less light. A new study that uses ultrafast nanometric imaging found good and bad emitters among populations of carbon dots. This observation suggests that by selecting only super-emitters, carbon nanodots can be purified to replace toxic metal quantum dots in many applications, the researchers said.
TINY DIAMONDS PROVE AN EXCELLENT MATERIAL FOR ACCELERATOR COMPONENTS
When it comes to producing high-quality electron beams like those found in state-of-the-art scientific equipment like free-electron lasers, ultrafast electron diffraction and imaging and wakefield accelerators, scientists have looked to photocathode technology as a way to convert light to electrons. These tools give researchers a way to more deeply penetrate into materials and atomic structure and behavior under real-world conditions.
A DROP OF RUBBING ALCOHOL AND OFFICE LAMINATOR PROVIDES A MANUFACTURABILITY BOOST FOR NANOMATERIALS
Vanderbilt engineers used a drop of rubbing alcohol, an office laminator and creativity to develop scalable processes for manufacturing single atom thin membranes. Their membranes outperformed state-of-the-art commercial dialysis membranes and the approach is fully compatible with roll-to-roll manufacturing.
