University of Chicago, Argonne scientists tame photon-magnon interactions In a first-of-its-kind discovery, researchers in the University of Chicago’s Pritzker School of Molecular Engineering and Argonne National Laboratory announced they can directly control the interactions between two types of q.
The colorful community was built in just 13 weeks!
A colorful village of 40 tiny homes opened up in Los Angeles earlier this month. While each 64-foot square unit can only hold one to two people, the project as a whole is a huge step forward when it comes to solving one of the city’s biggest crises: homelessness.

National Academies study says fusion can help decarbonize US energy, calls for public-private approach to pilot plant operation by 2035–40.
Electricity generated by fusion power plants could play an important role in decarbonizing the U.S. energy sector by mid-century, says a new consensus study report from the National Academies of Sciences, Engineering, and Medicine, which also lays out for the first time a set of technical, economic, and regulatory standards and a timeline for a U.S. fusion pilot plant that would begin producing energy in the 2035–40 time frame.
To achieve this key step toward commercialization, the report calls for an aggressive public-private effort to produce by 2028 a pilot plant design that can, when built, accommodate any of the developmental approaches seeking to realize fusion’s potential as a safe, carbon-free, on-demand energy source.
Engineers at the University of California San Diego have developed a soft, stretchy skin patch that can be worn on the neck to continuously track blood pressure and heart rate while measuring the wearer’s levels of glucose as well as lactate, alcohol, or caffeine. It is the first wearable device that monitors cardiovascular signals and multiple biochemical levels in the human body at the same time.
“This type of wearable would be very helpful for people with underlying medical conditions to monitor their own health on a regular basis,” said Lu Yin, a nanoengineering Ph.D. student at UC San Diego and co-first author of the study published on February 152021, in Nature Biomedical Engineering. “It would also serve as a great tool for remote patient monitoring, especially during the COVID-19 pandemic when people are minimizing in-person visits to the clinic.”
Such a device could benefit individuals managing high blood pressure and diabetes — individuals who are also at high risk of becoming seriously ill with COVID-19. It could also be used to detect the onset of sepsis, which is characterized by a sudden drop in blood pressure accompanied by a rapid rise in lactate level.
Researchers unlocked the electronic properties of graphene by folding the material like origami paper.
Researchers at Monash University’s Department of Chemical Engineering, IITB-Monash Research Academy Mumbai, and The Indian Institute of Technology’s Department of Chemical Engineering have used reactive flash volatilisation (RFV) gasification technology to produce hydrogen using microalgae, giving rise to newer and cleaner forms of energy.
“” This type of wearable would be very helpful for people with underlying medical conditions to monitor their own health on a regular basis,” co-first author of the study Lu Yin said in a news release.
New wearable device converts body heat into electricity.
“It would also serve as a great tool for remote patient monitoring, especially during the COVID-19 pandemic when people are minimizing in-person visits to the clinic,” Yin, a nano-engineering doctoral student at the University of California, San Diego.
In addition to monitoring chronic conditions like diabetes and high blood pressure, as well as pinpointing the onset of sepsis, the patch could help predict people at risk of becoming severely ill with COVID-19.

Dr. Vega-Castillo was previously Deputy Minister of Science and Technology and also served as Vice President for Research and Outreach in the Instituto Tecnológico de Costa Rica (ITCR) where she promoted the strengthening of research and outreach, and linkages with the national and international sector for increasing the scientific publication and patents.
The plasma compression fusion device (PCFD) generates the energy gain by plasma compression-induced nuclear fusion. This concept has the capability of maximizing the product of plasma pressure and energy confinement time to maximize the energy gain, and thus give rise to fusion ignition conditions. The preferred embodiment of this original concept uses a hollow cross-duct configuration of circular cross section in which the concentrated magnetic energy flux from two pairs of opposing curved-headed counter-spinning conical structures (possibly made from an alloy of tungsten with high capacitance) whose outer surfaces are electrically charged compresses a gaseous mixture of fusion fuel into a plasma, heated to extreme temperatures and pressures. The generated high-intensity electromagnetic (EM) radiation heats the plasma and the produced magnetic fields confine it in between the counter-spinning conical structures, named the dynamic fusors (four of them-smoothly curved apex sections opposing each other in pairs). The dynamic fusors can be assemblies of electrified grids and toroidal magnetic coils, arranged within a conical structure whose outer surface is electrically charged. The cross-duct inner surface surrounding the plasma core region is also electrically charged and vibrated in an accelerated mode to minimize the flux of plasma particles (including neutrals) from impacting the PCFD surfaces and initiating a plasma quench. The fusion fuel (preferably deuterium gas) is introduced into the plasma core through the counterspinning conical structures, namely, injected through orifices in the dynamic fusor heads. There is envisioned another even more compact version of this concept, which uses accelerated vibration in a linear-duct configuration (using two counterspinning dynamic fusors only) and would best be suited for fusion power generation on aircraft, or main battle tanks. The concept uses controlled motion of electrically charged matter through accelerated vibration and/or accelerated spin subjected to smooth, yet rapid acceleration transients, to generate extremely high-energy/high-intensity EM radiation (fields of high-energy photons) which not only confines the plasma but also greatly compresses itso as to produce a high power density plasma burn, leading to ignition. The PCFD concept can produce power in the gigawatt to terawatt range (and higher) with input power in the kilowatt to megawatt range and can possibly lead to ignition (selfsustained) plasma burn. Several important practical engineering and operational issues with operating a device such as the PCFD are discussed.
