'Growing' electronic components directly onto a semiconductor block avoids messy, noisy oxidation scattering that slows and impedes electronic operation. A UNSW study out this month shows that the resulting high-mobility components are ideal candidates for high-frequency, ultra-small electronic devices, quantum dots, and for qubit applications in quantum computing. Smaller … [Read more...] about Home-grown semiconductors for faster, smaller electronics: ‘Growing’ electronic components directly onto a semiconductor block avoids messy, noisy oxidation scattering

One of the biggest marketing trends in the online shopping industry is personalization through curated product recommendations; however, it can change whether people buy a product they had been considering, according to new University of California San Diego research. The study by Uma R. Karmarkar, assistant professor at the UC San Diego Rady School of Management and School of … [Read more...] about Online product displays can shape your buying behavior

A study led by researchers at North Carolina State University developed a new method that enables quantum computers to measure the thermodynamic properties of systems by calculating the zeros of the partition function. "We've illustrated a new way to get at thermodynamic properties of a system, such as free energy, entropy, and other properties that are too complex to currently … [Read more...] about Partition function zeros are ‘shortcut’ to thermodynamic calculations on quantum computers

Since the beginning of the pandemic, researchers worldwide have been looking for ways to treat COVID-19. And while the COVID-19 vaccines represent the best measure to prevent the disease, therapies for those who do get infected remain in short supply. A new groundbreaking study from U-M reveals several drug contenders already in use for other purposes -- including one dietary … [Read more...] about Study reveals existing drugs that kill SARS-CoV2 in cells

Since the early days of the COVID pandemic, scientists have aggressively pursued the secrets of the mechanisms that allow severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to enter and infect healthy human cells. Early in the pandemic, University of California San Diego's Rommie Amaro, a computational biophysical chemist, helped develop a detailed visualization of … [Read more...] about Researchers discover hidden SARS-CoV-2 ‘gate’ that opens to allow COVID infection: Supercomputing-derived movies reveal details of deceptive sugar coating on spike protein, presenting new possibilities to block cell entry and infection

An international study led by the University of Bonn has found evidence of a long-sought effect in accelerator data. The so-called "triangle singularity" describes how particles can change their identities by exchanging quarks, thereby mimicking a new particle. The mechanism also provides new insights into a mystery that has long puzzled particle physicists: Protons, neutrons … [Read more...] about Transformation in the particle zoo: Evidence of a long-sought effect in CERN data

Whether a robot or a person delivers your package, the carbon footprint would essentially be the same, according to a University of Michigan study that could help inform the future of automated delivery as the pandemic fuels a dramatic rise in online shopping. The researchers examined the environmental impacts of advanced residential package delivery scenarios that use electric … [Read more...] about Package delivery robots’ environmental impacts: Automation matters less than vehicle type

Research led by a Wayne State University Department of Mathematics professor is aiding researchers in Wayne State's Department of Psychiatry and Behavioral Neurosciences in analyzing fMRI data. fMRI is the preeminent class of signals collected from the brain in vivo and is irreplaceable in the study of brain dysfunction in many medical fields, including psychiatry, neurology … [Read more...] about From mathematics to medicine: Applying complex mathematics to analyze fMRI data

Wearable health technologies are vastly popular with people wanting to improve their physical and mental health. Everything from exercise, sleep patterns, calories consumed and heart rhythms can be tracked by a wearable device. But timely and accurate data is also especially valuable for doctors treating patients with complicated health conditions using virtual care. A new … [Read more...] about Tailoring wearable technology and telehealth in treating Parkinson’s disease: Timely and accurate tremor data can improve virtual appointments

Violent activity on our Sun leads to some of the most extreme space weather events on Earth, impacting systems such as satellites, communications systems, power distribution and aviation. The roughly 11 year cycle of solar activity has three 'seasons', each of which affects the space weather felt at Earth differently: (i) solar maximum, the sun is active and disordered, when … [Read more...] about Fast changes between the solar seasons resolved by new sun clock
