HOW MUCH DOES THE REAL SUPPORTIVE DOINGS COST?
The cheap question but seems rhetorical update on all the SHAB TECHNOLOGY PLANET social media platforms.
‘THE SMELLICOPTER,’ AN OBSTACLE-AVOIDING DRONE THAT USES A LIVE MOTH ANTENNA TO SEEK OUT SMELLS
One huge advantage of drones is that these little robots can go places where people can’t, including areas that might be too dangerous, such as unstable structures after a natural disaster or a region with unexploded devices.
RESEARCH: MILLIONS OF SMART DEVICES VULNERABLE TO HACKING
Researchers at a cybersecurity firm say they have identified vulnerabilities in software widely used by millions of connected devices—flaws that could be exploited by hackers to penetrate business and home computer networks and disrupt them.
ROBOT VACUUM CLEANERS CAN SPY ON PRIVATE CONVERSATIONS
When your robot vacuum cleaner does its work around the house, beware that it could pick up private conversations along with the dust and dirt. Computer scientists from NUS have demonstrated that it is indeed possible to spy on private conversations using a common robot vacuum cleaner and its built-in Light Detection and Ranging (Lidar) sensor.
? PHYSICS NEWS⚙♨:
ELEMENTARY PARTICLES PART WAYS WITH THEIR PROPERTIES
“Spooky action at a distance,” Einstein’s summation of quantum physics, has been a criticism of quantum mechanics since the field emerged. So far, descriptions of entangled particles to explain their apparently faster-than-light responses, and even explanations for the phase shifts induced by an electromagnetic field in regions where it is zero—the “Aharonov-Bohm” effect—have mostly addressed these concerns. However, recent theoretical and experimental demonstrations of a “counterfactual” quantum communication protocol have proved difficult to explain in terms of physical cause and effect. In this kind of quantum communication, observers on either side of a “transmission channel” exchange information without any particle passing between them—spooky indeed.
ADAPTING MAGNETOMETERS FOR NOISY, PHYSICALLY DEMANDING ENVIRONMENTS
Researchers routinely measure magnetic fields to better understand a vast array of natural phenomena including geological movements, solar flares, neuronal communication in the brain, and molecular-scale chemical processes.
BATTERIES MIMIC MAMMAL BONES FOR STABILITY
Sodium-ion batteries are poised to replace lithium-ion batteries for large-scale electrical energy storage. They offer several advantages over lithium-ion batteries, particularly due to the widespread abundance of sodium.
? EARTH NEWS?:
RESEARCH BRIEF: GLOBAL TRENDS IN NATURE’S CONTRIBUTIONS TO PEOPLE
In a new study published today in the Proceedings of the National Academy of Sciences, a research team co-led by the University of Minnesota, examined the risks to human well-being and prosperity stemming from ongoing environmental degradation.
METHANE IN TIDAL MARSHES
A pair of University of Delaware researchers were studying “blue carbon”—the carbon stored in coastal ecosystems such as mangrove forests, salt marshes or sea grasses—when they found something no one expected to see in a salt marsh: large quantities of methane in the soil.
MAPPING GLOBAL IMPACTS FOR ALL VEGETABLE OILS KEY TO SUSTAINABILITY
A lack of data on the environmental and social impacts of vegetable oil crops stands in the way of informed discussions about their relative sustainability, according to a new study by members of the IUCN’s Palm Oil Task Force.
? ASTRONOMY & SPACE NEWS??:
CAPSULE WITH ASTEROID SAMPLES ARRIVES IN JAPAN FOR RESEARCH
Japanese space agency officials were delighted Tuesday by the return of a small capsule containing asteroid soil samples obtained by their Hayabusa2 spacecraft and were anxiously waiting to look inside after preparations are complete.
NASA OUTLINES SCIENCE GOALS FOR FUTURE ASTRONAUTS ON MOON
The US space agency NASA published a voluminous report on Monday outlining the scientific priorities for the Artemis III astronauts it intends to send to the Moon in 2024.
MICROBES TO DEMONSTRATE BIOMINING OF ASTEROID MATERIAL ABOARD SPACE STATION
As humanity moves closer to the possibility of living and working millions of miles from Earth on planets like Mars, scientists are looking beyond our planet at how to acquire the materials needed to establish a self-sustaining presence in space.
? NANOTECHNOLOGY NEWS⛄☃:
NANOELECTROMECHANICAL TAGS FOR TAMPER-PROOF PRODUCT IDENTIFICATION AND AUTHENTICATION
Researchers in cybersecurity aim to realize truly unclonable identification and authentication tags to defend global systems from ever-increasing counterfeit attacks. In a new report now published on Nature: Microsystems & Nanoengineering, Sushant Rassay and a team of researchers in electrical and computer engineering at the University of Florida, U.S., demonstrated nanoscale tags to explore an electromechanical spectral signature as a fingerprint based on the inherent randomness of the fabrication process. The ultraminiature size and transparent constituents of the nanoelectromechanical (NEMS) tags provided substantial immunity to physical tampering and cloning efforts. The NEMS can typically convert forms of mechanical and vibrational energy from the environment into electric power by developing reliable power sources for ultralow power wireless electronic devices. The team also developed adaptive algorithms to digitally translate the spectral signature into binary fingerprints. The experiments highlighted the potential of clandestine (stealthy) NEMS to secure identification and authentication across a range of products and consumer goods.
TINY NANOSPINDLES ENHANCE USE OF ULTRASOUND TO FIGHT CANCER
Ultrasound can be used to treat cancer when used in combination with molecules that sensitize the system to sound waves. These sonosensitizers generate toxic reactive oxygen species that attack and kill tumor cells.
CATHODIC CORROSION—DEVASTATING BUT PREDICTABLE
An indian stepwell on a nanoscale. That is what postdoc Nakkiran Arulmozhi calls the pattern he saw when he corroded a special kind of platinum crystal. The unique images show the destructiveness of the process, but also show how predictable it is.
