(via sciencedaily.com)
Original source 
Scientists have developed a fluoride-containing electrolyte for lithium metal batteries that could boost the electric vehicle industry. The usefulness of this electrolyte extends to other types of advanced battery systems beyond lithium ion.
Published There may be good news about the oceans in a globally warmed world
(via sciencedaily.com)
Original source 
An analysis of oxygen levels in Earth's oceans may provide some rare, good news about the health of the seas in a future, globally warmed world. A study analyzing ocean sediment shows that ocean oxygen levels in a key area were higher during the Miocene warm period, some 16 million years ago when the Earth's temperature was hotter than it is today.
Published Starlight and the first black holes: researchers detect the host galaxies of quasars in the early universe
(via sciencedaily.com)
Original source 
For the first time, the James Webb Space Telescope has revealed starlight from two massive galaxies hosting actively growing black holes -- quasars -- seen less than a billion years after the Big Bang.
Published A surprise chemical find by ALMA may help detect and confirm protoplanets
(via sciencedaily.com)
Original source 
Scientists studying the protoplanetary disk around a young star have discovered the most compelling chemical evidence to date of the formation of protoplanets. The discovery will provide astronomers with an alternate method for detecting and characterizing protoplanets when direct observations or imaging are not possible.
Published A jaw-dropping conundrum: Why do mammals have a stiff lower jaw?
(via sciencedaily.com)
Original source 
The lower jaws of lizards, birds, fish and even dinosaurs are comprised of multiple bones per side. Yet mammals diverged from all other vertebrates and settled on just one bone, repurposing the extra bones into a more elaborate inner ear, perhaps the better to hear. The single bone per side, fused in primates into one jawbone, makes the jaw more rigid. A paleontologist asks, Did the stiffer, rigid jaw make mammals more successful?
Published Magnetic bacteria point the way
(via sciencedaily.com)
Original source 
Magnetotactic bacteria, which can align with the Earth's magnetic field, have been discovered in a new location. Previously observed on land and in shallow water, analysis of a hydrothermal vent has proven that they can also survive deep under the ocean. The bacteria were able to exist in an environment that was not ideal for their typical needs. Magnetotactic bacteria are of interest not only for the role they play in Earth's ecosystem, but also in the search for extraterrestrial life. Evidence of their existence can remain in rocks for billions of years. Their magnetic inclinations can also provide a record of how magnetic poles have shifted over time. This new discovery brings hope to researchers that the magnetic bacteria might be found in yet more unexpected locations, on Earth and perhaps even on Mars or beyond.
Published Dogs and humans process body postures similarly in their brains
(via sciencedaily.com)
Original source 
A new study shows that information from body postures plays a similarly important role for dogs as it does for humans. The results offer new insights into how dogs and humans perceive each other and their environment. They confirm that the temporal lobe plays a central role in social communication and perception.
Published This self-driving boat maps underwater terrain
(via sciencedaily.com)
Original source 
Engineers concoct an easier way for scientists to study underwater topography.
Published How the brain processes numbers -- New procedure improves measurement of human brain activity
(via sciencedaily.com)
Original source 
Measuring human brain activity down to the cellular level: until now, this has been possible only to a limited extent. With a new approach it will now be much easier. The method relies on microelectrodes along with the support of brain tumor patients, who participate in studies while undergoing 'awake' brain surgery. This enabled the team to identify how our brain processes numbers.
Published New driver for shapes of small quark-gluon plasma drops?
(via sciencedaily.com)
Original source 
New measurements of how particles flow from collisions of different types of particles at the Relativistic Heavy Ion Collider (RHIC) have provided new insights into the origin of the shape of hot specks of matter generated in these collisions. The results may lead to a deeper understanding of the properties and dynamics of this form of matter, known as a quark-gluon plasma (QGP).
Published European bird communities move to cooler areas, but mountain ranges and coastlines 'control the traffic'
(via sciencedaily.com)
Original source 
A recent study shows that European bird communities have shifted northeastward in the past 30 years. These shifts are faced with obstacles such as mountain ranges and coastlines. Overall, bird communities are moving towards cooler areas but not fast enough to keep up with increasing temperatures.
Published Specialization in sheep farming, a possible strategy for Neolithic communities in the Adriatic to expand throughout the Mediterranean
(via sciencedaily.com)
Original source 
The specialization in sheep in the early Neolithic populations of Dalmatia, Croatia, may have been related to the rapid expansion of these communities and the spread of agriculture throughout the central and western Mediterranean.
Published Emulating how krill swim to build a robotic platform for ocean navigation
(via sciencedaily.com)
Original source 
Researchers have presented important first steps in building underwater navigation robots.
Published Newly discovered Jurassic fossils in Texas
(via sciencedaily.com)
Original source 
Scientists have filled a major gap in the state's fossil record -- describing the first known Jurassic vertebrate fossils in Texas. The weathered bone fragments are from the limbs and backbone of a plesiosaur, an extinct marine reptile.
Published Researchers make a quantum computing leap with a magnetic twist
(via sciencedaily.com)
Original source 
Scientists and engineers have announced a significant advancement in developing fault-tolerant qubits for quantum computing. In a pair of articles, they report that, in experiments with flakes of semiconductor materials -- each only a single layer of atoms thick -- they detected signatures of 'fractional quantum anomalous Hall' (FQAH) states. The team's discoveries mark a first and promising step in constructing a type of fault-tolerant qubit because FQAH states can host anyons -- strange 'quasiparticles' that have only a fraction of an electron's charge. Some types of anyons can be used to make what are called 'topologically protected' qubits, which are stable against any small, local disturbances.
Published Genetic secrets of America's favorite snack
(via sciencedaily.com)
Original source 
In its simplest form, popcorn is pretty uncomplicated. Most supermarket varieties offer the choice of two kernel colors, yellow or white, and two kernel shapes, pointed or pearl. When popped, the flake typically expands into one of two shapes: mushroom or butterfly. But there's more to popcorn than meets the eye. New research reveals a wealth of untapped diversity lurking in popcorn's genetic code.
Published Freely available risk model for hurricanes, tropical cyclones
(via sciencedaily.com)
Original source 
As human-driven climate change amplifies natural disasters, hurricanes and typhoons stand to increase in intensity. Until now, there existed very few freely available computer models designed to estimate the economic costs of such events, but a team of researchers has recently announced the completion of an open-source model that stands to help countries with high tropical cyclone risks better calculate just how much those storms will impact their people and their economies.

Published Bigger bottles keep champagne bubbly for decades
(via sciencedaily.com)
Original source 
Tiny bubbles bursting in a drinker's face and the bite of carbonation are all part of the experience when sipping champagne and sparkling wines. But how long can these drinks be stored in sealed bottles before they go flat? According to researchers, the answer depends on the container's size. They estimate a 40-year shelf-life for 750-milliliter (25-ounce) bottles, and 82 and 132 years for 1.5-liter (50-ounce) and 3-liter (101-ounce) bottles, respectively.
