BEHIND THOSE DANCING ROBOTS, SCIENTISTS HAD TO BUST A MOVE
The man who designed some of the world’s most advanced dynamic robots was on a daunting mission: programming his creations to dance to the beat with a mix of fluid, explosive and expressive motions that are almost human.
BIO-INSPIRED ROBOTICS: LEARNING FROM DRAGONFLIES
It is a high-speed movement: within fractions of a second the mouthparts of the dragonfly larvae spring forwards to seize its prey. For decades, researchers had assumed that this action must have been driven primarily by hydraulic pressure. Now, for the first time, scientists at Kiel University (CAU) have completely decrypted the biomechanical functional principle of what is known as the labial mask of dragonfly larvae. A vital contribution to this discovery was made by the team led by Dr. Sebastian Büsse of the Zoological Institute in its development of a bio-inspired robot with the operating principle of the complex mouthparts adapted to test its own hypothesis—the technology used here could lead to a significant enhancement of agile robot systems. The results of the ambitious research project were published on Wednesday 20 January in the renowned specialist journal Science Robotics.
SAMSUNG ANNOUNCES 14-INCH OLED SCREENS THAT RUN AT 90HZ
Samsung Display, a subsidiary of The Samsung Group, has announced that it will begin production of its new 14-inch OLED screen that runs at 90 Hz for laptops this spring. In their announcement on their blog, CEO Choi Choo-sun claimed that the screens will be in full production starting March 21 of this year.
🗞 PHYSICS NEWS⚙♨:
SEARCH FOR AXIONS FROM NEARBY STAR BETELGEUSE COMES UP EMPTY
The elusive axion particle is many times lighter than an electron, with properties that barely make an impression on ordinary matter. As such, the ghost-like particle is a leading contender as a component of dark matter—a hypothetical, invisible type of matter that is thought to make up 85 percent of the mass in the universe.
DEFECTS MAY HELP SCIENTISTS UNDERSTAND THE EXOTIC PHYSICS OF TOPOLOGY
Real-world materials are usually messier than the idealized scenarios found in textbooks. Imperfections can add complications and even limit a material’s usefulness. To get around this, scientists routinely strive to remove defects and dirt entirely, pushing materials closer to perfection. Now, researchers at the University of Illinois at Urbana-Champaign have turned this problem around and shown that for some materials defects could act as a probe for interesting physics, rather than a nuisance.
SCIENTISTS USE DIAMONDS TO GENERATE BETTER ACCELERATOR BEAMS
Beam-driven wakefield acceleration approaches are promising candidates for future large-scale machines, including X-ray free electron lasers and linear colliders, as they have the potential to improve efficiency and reduce operation cost.
🗞 EARTH NEWS🌏:
LAKE HEATWAVES MAY BECOME HOTTER AND LONGER, NEW STUDY SUGGESTS
Lake heatwaves—periods of extreme warm surface water temperature in lakes—may become hotter and longer by the end of the 21st century, according to a study published in Nature, increasing the link between climate change and extreme events.
AIR POLLUTION LEVELS DEPEND ON DRIZZLE RATES
Scientists from Lawrence Livermore National Laboratory (LLNL), Scripps Institution of Oceanography and international collaborators have shown that an improved representation of drizzle rates leads to more pollution in the atmosphere. The research appears in Nature Geoscience.
AIR POLLUTION LINKED TO INCREASED MENTAL HEALTH OUTPATIENT VISITS
More pollution in the air could be linked to higher rates of mental health service use, researchers at the Yale School of Public Health found in a new study.
🗞 ASTRONOMY & SPACE NEWS🌪🎇:
SCIENTISTS FIND BLACK HOLES COULD REACH ‘STUPENDOUSLY LARGE’ SIZES
A recent study suggests the possible existence of ‘stupendously large black holes’ or SLABS, even larger than the supermassive black holes already observed in the centers of galaxies.
MUCH OF EARTH’S NITROGEN WAS LOCALLY SOURCED
Where did Earth’s nitrogen come from? Rice University scientists show one primordial source of the indispensable building block for life was close to home.
SOLAR SYSTEM FORMATION IN TWO STEPS
An international team of researchers from the University of Oxford, LMU Munich, ETH Zurich, BGI Bayreuth, and the University of Zurich discovered that a two-step formation process of the early Solar System can explain the chronology and split in volatile and isotope content of the inner and outer Solar System.
🗞 NANOTECHNOLOGY NEWS⛄☃:
DRUG-DELIVERY MICROCAPSULES TAGGED WITH ZIRCONIUM-89 CAN BE TRACKED BY PET IMAGING
University of Alabama at Birmingham polymer and radionuclide chemists report what they say “may represent a major step forward in microcapsule drug delivery systems.”
TAKING SIEVING LESSONS FROM NATURE
Generating membranes using electrochemical polymerization, or electropolymerization, could provide a simple and cost-effective route to help various industries meet increasingly strict environmental regulations and reduce energy consumption.
RESEARCHERS DEVELOP NEW GRAPHENE NANOCHANNEL WATER FILTERS
When sheets of two-dimensional nanomaterials like graphene are stacked on top of each other, tiny gaps form between the sheets that have a wide variety of potential uses. In research published in the journal Nature Communications, a team of Brown University researchers has found a way to orient those gaps, called nanochannels, in a way that makes them more useful for filtering water and other liquids of nanoscale contaminants.
