EXAMINING HOW HUMANS DEVELOP TRUST TOWARDS EMBODIED VIRTUAL AGENTS
Embodied virtual agents (EVAs), graphically represented 3D virtual characters that display human-like behavior, could have valuable applications in a variety of settings. For instance, they could be used to help people practice their language skills or could serve as companions for the elderly and people with psychological or behavioral disorders.
BAIDU ROLLS OUT PAID DRIVERLESS TAXI SERVICE IN BEIJING
Chinese tech giant Baidu rolled out its paid driverless taxi service on Sunday, making it the first company to commercialize autonomous driving operations in China.
APT ACTORS EXPLOIT AUTHENTICATION BYPASS TECHNIQUES AND PULSE SECURE ZERO-DAY
American cybersecurity firm Mandiant has recently faced a number of security incidents surrounding compromises of Pulse Secure VPN appliances. The attackers involved have used authentication bypass techniques to circumvent VPN security parameters. The threat groups appear to have installed APT via web shells to monitor systems despite VPN functionality.

A NEW WAY TO MAKE AR/VR GLASSES
“Image” is everything in the $20 billion market for AR/VR glasses. Consumers are looking for glasses that are compact and easy to wear, delivering high-quality imagery with socially acceptable optics that don’t look like “bug eyes.”
1D MODEL HELPS CLARIFY IMPLOSION PERFORMANCE AT NIF
In inertial confinement fusion (ICF) experiments at the National Ignition Facility (NIF), a spherical shell of deuterium-tritium fuel is imploded in an attempt to reach the conditions needed for fusion, self-heating and eventual ignition. Since theory and simulations indicate that ignition efficacy in one-dimension (1D) improves with increasing imploded fuel convergence ratio, it is useful to understand the sensitivity of the scale-invariant fuel convergence on all measurable or inferable 1D parameters.
A PHYSICS PERSPECTIVE ON WOUND HEALING
In material physics understanding how systems interact across the interfaces separating them is of central interest. But can physical models clarify similar concepts in living systems, such as cells? Physicists at the University of Geneva (UNIGE), in collaboration with the University of Zurich (UZH), used the framework of disordered elastic systems to study the process of wound healing—the proliferation of cell fronts which eventually join to close a lesion. Their study identified the scales of the dominant interactions between cells which determine this process. The results, published in the journal Scientific Reports, will allow better analysis of cell front behavior, in terms of both wound healing and tumor development. In the future, this approach may offer personalized diagnostics to classify cancers and better target their treatment, and identify new pharmacological targets for transplantation.

OCEANS’ MICROSCOPIC PLANTS—DIATOMS—CAPTURE CARBON DIOXIDE VIA BIOPHYSICAL PATHWAYS
Diatoms are tiny unicellular plants—no bigger than half a millimeter—which inhabit the surface water of the world’s oceans where sunlight penetration is plenty. Despite their modest size, they are one of the world’s most powerful resources for removing carbon dioxide (CO2) from the atmosphere. They currently remove, or “fix,” 10-20 billion metric tons of CO2 every year by the process of photosynthesis. But not much is known about which biological mechanisms diatoms use, and whether these processes might become less effective with rising ocean acidity, temperatures, and, in particular, CO2 concentrations. A new study in Frontiers in Plant Science shows that diatoms predominantly use one pathway to concentrate CO2 at the vicinity of carbon fixing enzyme and that this continues to operate even at higher CO2 concentrations.
LOCAL IMPACTS FROM FRACKING THE EAGLE FORD
Hydraulic fracturing to extract trapped fossil fuels can trigger earthquakes. Most are so small or far from homes and infrastructure that they may go unnoticed; others can rattle windows, sway light fixtures and jolt people from sleep; some have damaged buildings

DEEP SPACE LISTENING: 6000 HOURS OF RESEARCH TO HEAR CONTINUOUS GRAVITATIONAL WAVES
When searching for lost keys, there are a number of possible strategies. You might try moving from room to room, casting your eye over every flat surface, in the hope of spotting the missing keys. Of course, this assumes that they are somewhere in plain sight; if they’re hidden under a newspaper or have fallen behind the sofa, you’ll never spot them. So which is the best strategy?
THE PATCHY ENVIRONMENT OF A RARE COSMIC EXPLOSION REVEALED
Scientists from the National Centre for radio Astrophysics of the Tata Institute of Fundamental Research (NCRA-TIFR) Pune used the upgraded Giant Metrewave Radio Telescope (uGMRT) to determine that AT 2018 cow, the first of a newly discovered class of cosmic explosions, has an extremely patchy environment. Sources like AT 2018cow release an enormous amount of energy, nonetheless fade extremely rapidly. This along with their extremely blue color has led to them being called FBOTs for Fast Blue Optical Transient. This is the first observational evidence of inhomogeneous emission from an FBOT. The origins of FBOTs are still under debate, but proposed models include explosion of a massive star, collision of an accreting neutron star and a star, merger of two white dwarfs, etc.
? NANOTECHNOLOGY NEWS⛄☃:
FLEXIBLE, EASY-TO-SCALE NANORIBBONS MOVE GRAPHENE TOWARD USE IN TECH APPLICATIONS
From radio to television to the internet, telecommunications transmissions are simply information carried on light waves and converted to electrical signals.
NANOTECHNOLOGY OFFERS NEW HOPE FOR BOWEL CANCER PATIENTS
Bowel cancer survival rates could be improved if chemotherapy drugs were delivered via tiny nanoparticles to the diseased organs rather than oral treatment.
