Bringing 400-million-year-old fossilized armored worms to 'virtual' life

An international team of scientists from the United States and Australia, led by Sarah Jacquet at the University of Missouri, has documented the discovery of two new species of fossilized armored worms in Australia—Lepidocoleus caliburnus and Lepidocoleus shurikenus—dating from about 400 million years ago. Then, using the micro-CT imaging capabilities of the MU X-ray Microanalysis Core facility, the researchers were able to develop first-of-its-kind digital 3D-models of the species' individual armor plates by virtually examining the armored skeletons of these ancient worms, called machaeridians. from Phys.org - latest science and technology news stories https://ift.tt/3xCBydm

Black rot disease in cabbages, radishes and related cruciferous crops may have disastrous consequences for the yield and production of marketable plants. The bacterium Xanthomonas campestris is the major cause of black rot disease, which works by slowing several light-mediated biological processes. Behind this biological retardation lies a complicated signaling cascade that is balanced by specialized proteins such as phytochromes. from Phys.org - latest science and technology news stories https://ift.tt/3FUriQT

New study shows electric fields can improve the efficiency of wastewater purification

Ammonia is one of many pollutants present in wastewater and can be toxic for marine and terrestrial life. Therefore, in a process called air stripping, it is removed from wastewater and later used as a fertilizer or fuel. Air stripping converts ammonia into a gas that can then escape the wastewater from its surface. But this process is not efficient: It is energy-intensive, and requires specific temperatures, air supply, and many chemicals, making it expensive. from Phys.org - latest science and technology news stories https://ift.tt/3rdlOwn

Hubble spots a swift stellar jet in Running Man Nebula

A jet from a newly formed star flares into the shining depths of reflection nebula NGC 1977 in this Hubble image. The jet (the orange object at the bottom center of the image) is being emitted by the young star Parengo 2042, which is embedded in a disk of debris that could give rise to planets. The star powers a pulsing jet of plasma that stretches over two light-years through space, bending to the north in this image. The gas of the jet has been ionized until it glows by the radiation of a nearby star, 42 Orionis. This makes it particularly useful to researchers because its outflow remains visible under the ionizing radiation of nearby stars. Typically the outflow of jets like this would only be visible as it collided with surrounding material, creating bright shock waves that vanish as they cool. from Phys.org - latest science and technology news stories https://ift.tt/3DUvXS7

Astronomers discover ancient brown dwarf with lithium deposits intact

Brown dwarfs, also known as "coffee colored dwarfs" or "failed stars" are the natural link between stars and planets. They are more massive than Jupiter but now sufficiently to burn hydrogen, which is the fuel the stars use to shine. For that reason these substellar objects were not observed until observers detected them in the mid 1990's. They are particularly interesting because it was predicted that some of them could preserve intact their content of lithium, sometimes known as "white petroleum" because of its rarity and its relevance. from Phys.org - latest science and technology news stories https://ift.tt/3DT5XXa

The Riemann conjecture unveiled by physics

A mystery of mathematics that has remained unsolved for more than 150 years can be unraveled thanks to a completely unexpected approach coming from statistical physics. This is the important conclusion of Giuseppe Mussardo, professor of Theoretical Physics at SISSA, and Andrè Leclair of Cornell University reported in an article just published in the Journal of Statistical Mechanics (JSTAT). The two scientists have shown that not only one can arrive at the solution to one of the most famous problems in mathematics, the Riemann conjecture, but that it is the physics of chaotic motions and the probability laws that regulate them that provide the elegant key to understand this great mathematical enigma. The research behind the article just published, lasted three years and the final part of it, the authors said, was "a real tour de force in the data analysis of an incredibly large set of prime numbers, the basic constituents of arithmetic, i.e. the real atoms of mathematics." f...

The University has now agreed a license agreement with the Bachl Group for the commercial use of the process and the products for building insulation. from Phys.org - latest science and technology news stories https://ift.tt/3HwCjJt

The next step in understanding the interaction among hadrons

In a recently published article in Physical Review Letters, the ALICE collaboration has used a method called femtoscopy to study the residual interaction between two-quark and three-quark particles. Through this measurement, an interaction between the ɸ meson (strange-antistrange quarks) and a proton (two up and one down quarks) was unveiled for the first time. from Phys.org - latest science and technology news stories https://ift.tt/3kLw2jx

These plants have been developed at laboratory level, and the team's results have been published in the journal Biodesign Research. from Phys.org - latest science and technology news stories https://ift.tt/3wVKFp8

Friend or foe: Do online recommender tools really improve decision making?

Artificial intelligence (AI) recommender tools are widely used by industries such as e-commerce, media, banking and utilities. The tool's algorithm uses website visitors' past online activity and other data, both implicit and explicit, to predict what that visitor would like to view or buy next, and then presents those options to them. This can be highly beneficial; for example, for customers, the recommender can save them time by suggesting options tailored to their tastes and needs. While, for companies, it can encourage consumers to spend more via their website and increase customer loyalty: in the case of streaming giant Netflix, it's estimated that its recommendation engine generates $1 billion annually.   from Phys.org - latest science and technology news stories https://ift.tt/3qIhhBT

New technique improves conversion of carbon dioxide into liquid fuels

Carbon dioxide (CO2), a product of burning fossil fuels and the most prevalent greenhouse gas, has the potential to be sustainably converted back into useful fuels. A promising route for turning CO2 emissions into a fuel feedstock is a process known as electrochemical reduction. But to be commercially viable, the process needs to be improved, to select for, or to yield, a higher amount of desirable carbon-rich products. from Phys.org - latest science and technology news stories https://ift.tt/3FpEfSp

Rice varieties with a high endosperm lipid content reduce starch digestibility and increase γ-oryzanol bioaccessibility

According to the Healthy China Initiative, the incidence rate of diabetes is 12.8% in China, with about 150 million patients, and the incidence rate of dyslipidemia is 18.6%, with about 160 million patients. Common rice has a relatively high percentage of digestible starch and is therefore considered as a kind of food with a high glycemic index (GI). Breeding new varieties of rice rich in resistant starch or slowly digestible starch can meet the needs of "diabetes and obesity" patients and make people eating healthy. from Phys.org - latest science and technology news stories https://ift.tt/3HoXmxI

Synthetic biology yields easy-to-use underwater adhesives

Several marine organisms, such as mussels, secrete adhesive proteins that allow them to stick to different surfaces under sea water. This attractive underwater adhesion property has inspired decades of research to create biomimetic glues for underwater repair or biological tissue repair. However, existing glues often do not have the desirable adhesion, are hard to use underwater, or are not biocompatible for medical applications. Now, there is a solution from synthetic biology. from Phys.org - latest science and technology news stories https://ift.tt/3wRKfjK
