CineMPC: AN ALGORITHM TO ENABLE AUTONOMOUS DRONE-BASED CINEMATOGRAPHY
Emerging technologies such as artificial intelligence (AI) algorithms, mobile robots and unmanned aerial vehicles (UAVs) could enhance practices in a variety of fields, including cinematography. In recent years, many cinematographers and entertainment companies specifically began exploring the use of UAVs to capture high-quality aerial video footage (i.e., videos of specific locations taken from above).
RESEARCHERS DEVELOP PASTA THAT MORPHS INTO SHAPE WHEN COOKED
People love pasta for its shapes—from tubes of penne and rigatoni to spirals of fusilli and rotini.
MAKING BITCOIN MORE SECURE
A computer science engineer at Michigan State University has a word of advice for the millions of bitcoin owners who use smartphone apps to manage their cryptocurrency: don’t. Or at least, be careful. Researchers from MSU are developing a mobile app to act as a safeguard for popular but vulnerable “wallet” applications used to manage cryptocurrency.

RAPID ROVERS, SPEEDY SANDS: FAST-TRACKING TERRAIN INTERACTION MODELING
Granular materials, such as sand and gravel, are an interesting class of materials. They can display solid, liquid, and gas-like properties, depending on the scenario. But things can get complicated in cases of high-speed vehicle locomotion, which cause these materials to enter a “triple-phase” nature, acting like all three fundamental phases of matter at the same time.
RESEARCHERS PROPOSE REPURPOSING TABLETOP SENSORS TO SEARCH FOR DARK MATTER
Scientists are certain that dark matter exists. Yet, after more than 50 years of searching, they still have no direct evidence for the mysterious substance.
NEW ALGORITHM USES A HOLOGRAM TO CONTROL TRAPPED IONS
Researchers have discovered the most precise way to control individual ions using holographic optical engineering technology.

CATASTROPHIC SEA-LEVEL RISE FROM ANTARCTIC MELTING POSSIBLE WITH SEVERE GLOBAL WARMING
The Antarctic ice sheet is much less likely to become unstable and cause dramatic sea-level rise in upcoming centuries if the world follows policies that keep global warming below a key 2015 Paris climate agreement target, according to a Rutgers coauthored study.
LONG-TERM MONITORING SHOWS SUCCESSFUL RESTORATION OF MINING-POLLUTED STREAMS
Many miles of streams and rivers in the United States and elsewhere are polluted by toxic metals in acidic runoff draining from abandoned mining sites, and major investments have been made to clean up acid mine drainage at some sites. A new study based on long-term monitoring data from four sites in the western United States shows that cleanup efforts can allow affected streams to recover to near natural conditions within 10 to 15 years after the start of abatement work.
DID THE DROP IN COVID-RELATED EMISSIONS AFFECT THE CLIMATE?
As social and economic activity ground to a halt around the world in 2020 in the face of the COVID-19 pandemic, emissions of greenhouse gases and aerosols dropped. In the United States, where lockdowns that began in March kept many Americans off the roads, emissions fell by almost 13%. Globally, carbon dioxide (CO2) emissions dropped by nearly 7%. However, it’s not clear that emissions will remain low as global economies open back up, which raises the question: What impact will the short-term drop in emissions have on the climate?

A NEW WINDOW TO SEE HIDDEN SIDE OF MAGNETIZED UNIVERSE
New observations and simulations show that jets of high-energy particles emitted from the central massive black hole in the brightest galaxy in galaxy clusters can be used to map the structure of invisible inter-cluster magnetic fields. These findings provide astronomers with a new tool for investigating previously unexplored aspects of clusters of galaxies.
SCIENTISTS MODEL SATURN’S INTERIOR
New Johns Hopkins University simulations offer an intriguing look into Saturn’s interior, suggesting that a thick layer of helium rain influences the planet’s magnetic field.
BLUE ORIGIN WILL FLY FIRST CREW TO SPACE IN JULY
Jeff Bezos’ Blue Origin will send its first crew to space on July 20 and is offering one of the seats to the winner of an online auction, the company said Wednesday.

USING FLEXIBLE MICROPARTICLES AS DRUG CARRIERS TO SHUTTLE NANOPARTICLES TO THE VASCULAR WALL
Drug carriers that target the vascular endothelium must adhere to the endothelial vessel wall to achieve clinical stability. The particle size is a critical physical property to prescribe particle margination within biological blood flows and those conducted in-lab. While microparticles are optimal for margination, nanoparticles are better for intracellular delivery. In a new report now on Science Advances, Margaret B. Fish and a research team in chemical engineering, pharmacology and cardiovascular medicine and engineering at the University of Michigan, Ann Arbor U.S., tested flexible hydrogel particles as carriers to transport nanoparticles to a diseased vascular wall. Based on the microparticle modulus, nanoparticle-loaded poly (ethylene glycol)-based hydrogel microparticles delivered more than 50-nm nanoparticles to the vessel wall, when compared to freely injected nanoparticles to achieve more than 3000 percent increase in delivery. The work showed the benefit of optimizing the efficiency margination of microparticles to enhance transport of nanocarriers to the vascular wall.
A MATERIAL KEYBOARD MADE OF GRAPHENE
Researchers at ETH Zurich have succeeded in turning specially prepared graphene flakes either into insulators or into superconductors by applying an electric voltage. This technique even works locally, meaning that in the same graphene flake regions with completely different physical properties can be realized side by side.
