A remarkable substance extracted from pigs enables the body to regenerate lost tissue, including fingertips and big chunks of muscle. And that may not be all it can do…
Hungarian tech company Platio is expanding the way people can harness solar energy. Its new solar pavers work on home driveways, patios and terraces. Learn more.
Satellite images suggest North Korea has almost built a facility large enough to store all of its nuclear missiles.
At 500 square feet, ICON’s stylish new structure was 3D-printed over the course of several days—but it only took 27 hours of labor to construct. The building will serve as a welcome center at Austin’s new Community First! Village—a 51-acre development that will provide affordable housing to men and women coming out of chronic homelessness. Six new 3D-printed homes will be added to the village by the end of this year—and ICON says that they can be built at significantly less cost than conventional homes.
A year ago, ICON proved it could 3D print a home you’d actually want to live in. Now, it’s building a cluster of 3D-printed homes for the homeless.

Alloy 617 — a combination of nickel, chromium, cobalt and molybdenum — has been approved by the American Society of Mechanical Engineers (ASME) for inclusion in its Boiler and Pressure Vessel Code. This means the alloy, which was tested by Idaho National Laboratory (INL), can be used in proposed molten salt, high-temperature, gas-cooled or sodium reactors. It is the first new material to be added to the Code in 30 years.
The Boiler and Pressure Vessel Code lays out design rules for how much stress is acceptable and specifies the materials that can be used for power plant construction, including in nuclear power plants. Adhering to these specifications ensures component safety and performance.
INL spent 12 years qualifying Alloy 617, with a USD15 million investment from the US Department of Energy. A team at INL, in collaboration with groups at Argonne National Laboratory and Oak Ridge National Laboratory, as well as industry consultants and international partners, has now received approval from ASME for the alloy’s inclusion in the Code. Designers working on new high-temperature nuclear power plant concepts now have more options when it comes to component construction materials.
Recently, Prof. Yang Xueming from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences and Prof. Yang Tiangang from the Southern University of Science and Technology discussed significant advances in the study of quantum resonances in atomic and molecular collisions at near absolute zero temperature. Their article was published in Science on May 7.
The rules of quantum mechanics govern all atomic and molecular collision processes. Understanding the quantum nature of atomic and molecular collisions is essential for understanding energy transfer and chemical reaction processes, especially in the low collisional energy region, where quantum effect is the most prominent.
A remarkable feature of quantum nature in atomic and molecular collision is quantum scattering resonances, but probing them experimentally has been a great challenge due to the transient nature of these resonances.
The company said it expects to “incur significant expenses this year” related to the development of and manufacturing of its potential vaccine. However, it added that it expects “a close matching of expenses and reimbursements for those expenses” from its award by the Biomedical Advanced Research and Development Authority.
BARDA, which is a part of the Department of Health and Human Services, last month warded Moderna up to $483 million in funding to accelerate development of the Covid-19 vaccine candidate.
The race to develop anything to fight the coronavirus is intensely competitive and investors are watching closely for signs of progress on treatments and vaccines. Moderna, as well as other companies in the race, is ramping up manufacturing ahead of approval so that it can rapidly distribute doses if their candidate proves effective against the virus and safe for humans.
For the first time, researchers have succeeded in creating strong coupling between quantum systems over a great distance. They accomplished this with a novel method in which a laser loop connects the systems, enabling nearly lossless exchange of information and strong interaction between them. In the journal Science, physicists from the University of Basel and University of Hanover reported that the new method opens up new possibilities in quantum networks and quantum sensor technology.
Quantum technology is currently one of the most active fields of research worldwide. It takes advantage of the special properties of quantum mechanical states of atoms, light, or nanostructures to develop, for example, novel sensors for medicine and navigation, networks for information processing and powerful simulators for materials sciences. Generating these quantum states normally requires a strong interaction between the systems involved, such as between several atoms or nanostructures.
Until now, however, sufficiently strong interactions were limited to short distances. Typically, two systems had to be placed close to each other on the same chip at low temperatures or in the same vacuum chamber, where they interact via electrostatic or magnetostatic forces. Coupling them across larger distances, however, is required for many applications such as quantum networks or certain types of sensors.
