Scientists detect and validate the longest-period exoplanet found with TESS      (via sciencedaily.com) 

Scientists have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which have orbital periods of 10-200 days and are at least six times Earth's radius. This recent discovery offers exciting research opportunities for the future of finding long-period planets that resemble those in our own solar system.

Researchers visualize activity of CRISPR genetic scissors      (via sciencedaily.com)     Original source 

Scientists have developed a new method to measure the smallest twists and torques of molecules within milliseconds. The method makes it possible to track the gene recognition of CRISPR-Cas protein complexes, also known as 'genetic scissors', in real time and with the highest resolution. With the data obtained, the recognition process can be accurately characterized and modeled to improve the precision of the genetic scissors.

Turning old maps into 3D digital models of lost neighborhoods      (via sciencedaily.com)     Original source 

Imagine strapping on a virtual reality headset and 'walking' through a long-gone neighborhood in your city -- seeing the streets and buildings as they appeared decades ago. That's a very real possibility now that researchers have developed a method to create 3D digital models of historic neighborhoods using machine learning and historic Sanborn Fire Insurance maps.

NeuWS camera answers 'holy grail problem' in optical imaging      (via sciencedaily.com)     Original source 

Engineers have demonstrated full-motion video camera technology that can 'see' through light-scattering media. The research could potentially be used in cameras that peer through fog, smoke, driving rain, murky water and parts of the body that hide tumors and other lesions.

Octopus sleep is surprisingly similar to humans and contains a wake-like stage      (via sciencedaily.com)     Original source 

Researchers have closely examined the brain activity and skin patterning in octopuses (Octopus laqueus) during active sleep and discovered that it closely resembles neural activity and skin patterning behavior seen when awake.

Life after death: Astronomers find a planet that shouldn't exist      (via sciencedaily.com)     Original source 

The star would have inflated up to 1.5 times the planet's orbital distance -- engulfing the planet in the process -- before shrinking to its current size at only one-tenth of that distance.

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.

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.

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.

Megalodon was no cold-blooded killer      (via sciencedaily.com)     Original source 

How the megalodon, a shark that went extinct 3.6 million years ago, stayed warm was a matter of speculation among scientists. Using an analysis of tooth fossils from the megalodon and other sharks of the same period, a study suggests the animal was able to maintain a body temperature well above the temperature of the water in which it lived. The finding could help explain why the megalodon went extinct during the Pliocene Epoch.
