This size places it in an exclusive club:...
A Q&A with two scientists aiming to overcome limitations in computing power and energy efficiency deliberately by designing brand-new microchips (CMOS silicon chips). A brief history of microelectronics and CMOS silicone chips Our laptop computers and smartphones are portable yet powerful due to silicon microelectronics, also known as integrated circuits or chips, the tiny minds behind...
A 2 mm by 2 mm integrated photonic chip developed by Jaime Cardenas, assistant professor of optics, and PhD student Meiting Song (lead author) will make interferometers—and therefore precision optics—even more powerful. Potential applications include more sensitive devices for measuring tiny flaws on mirrors, or dispersion of pollutants in the atmosphere, and ultimately, quantum...

Considerably increased risk in teenagers after the second dosage may call for sophisticated vaccination strategies. A case-control research study found an elevated relative risk of carditis associated with BNT162b2 (also known...

Homo Sapiens and Neanderthals Mating Across Groups Homo Sapiens and Neanderthals Mating Across Groups seem to be a new scientific discovery. Proof that cross-continental Stone Age networking occasions powered human evolution increased in 2021. Homo Sapiens may not have eliminated Neanderthals A long-lasting argument that Homo sapiens originated...
Nasa/JHU/Carnegie Credit Mercury is a really peculiar planet. The tiniest in the solar system and the one nearest to the sun, it rotates slowly in a 3:2 spin resonance and experiences hot temperatures of up to 430 degrees Celsius during the day and cold temperatures of -170 degrees Celsius at night. Its average density is...
Quantifying electric fields in semiconductor devices: The schematic shows electric field distribution in the channel of a GaN transistor; laser beams highlight the second harmonic generation (SHG) nature of the technique. credit: Yuke Cao Power-saving electronics are becoming increasingly important in the quest for a carbon-neutral world. Advancements in this technology are making it possible...
IHU Covid-19 New Variant - More Infectious than Omicron It was just recently that the new variant of covid-19, Omicron, was recognized first in South Africa multiply promptly around the globe, one more new Covid-19 variation is being reported from France which is believed to be increasingly more contagious than Omicron. Scientists have called the...
Scientists at the UAB and the UniZar have detected a human peptide located in the brain that prevents the α-synuclein aggregates associated with Parkinson's disease and helps prevent their neurotoxicity. The research released in Nature Communications suggests that this may be one of the organism's natural systems to combat aggregation. The learning might help...
A new graphene amplifier has been able to unlock hidden frequencies in the electromagnetic spectrum. Credit: Scitech Daily The Earth's atmosphere has been utilized as a 'laboratory' to perform a physics experiment in a research partnership involving the University of Strathclyde, which can help boost the efficiency of GPS. The research study displays a new method...
