Fermilab and partners achieve sustained, high-fidelity quantum teleportation
A viable quantum internet-a network in which information stored in qubits is shared over long distances through entanglement-would transform the fields of data storage, precision sensing and computing, ushering in a new era of communication. This month, scientists at Fermi National Accelerator Laboratory-a U.S. Department of Energy national laboratory affiliated with the University of Chicago-along with partners at five institutions took a significant step in the direction of realizing a quantum internet.

Ripples in space-time could provide clues to missing components of the universe
UChicago scientist lays out how LIGO gravitational waves could be scrambled, yielding information There's something a little off about our theory of the universe. Almost everything fits, but there's a fly in the cosmic ointment, a particle of sand in the infinite sandwich. Some scientists think the culprit might be gravity-and that subtle ripples in the fabric of space-time could help us find the missing piece.

Scientists pioneer new method of measuring electricity in cells
Electricity is a key ingredient in living bodies. We know that voltage differences are important in biological systems; they drive the beating of the heart and allow neurons to communicate with one another. But for decades, it wasn't possible to measure voltage differences between organelles-the membrane-wrapped structures inside the cell-and the rest of the cell.

Love and Hate in the Mouse Brain
Mounting behavior, that awkward thrusting motion dogs sometimes do against your leg, is usually associated with sexual arousal in animals, but this is not always the case. New research by Caltech neuroscientists that explores the motivations behind mounting behavior in mice finds that sometimes there is a thin line between love and hate (or anger) in the mouse brain.

Ten cool research stories you might have missed this year
There's been a lot going on in 2020, so nobody can be blamed for missing a few things. But amid a tumultuous year in which many pivoted to COVID-19 research , University of Chicago scholars and scientists have also been hard at work continuing to understand the planet and the universe we live in, to improve our lives, and to build a future that's clean, safe and sustainable.

The new device can continuously sense levels of virtually any protein or molecule in the blood. The researchers say it could be transformative for disease detection, patient monitoring and biomedical research. For even the most routine of medical checkups, a blood test is often the first order of business.
A new nanomaterial helps obtain hydrogen from a liquid energy carrier, in a key step toward a stable and clean fuel source Hydrogen is a sustainable source of clean energy that avoids toxic emissions and can add value to multiple sectors in the economy including transportation, power generation, metals manufacturing, among others.
Climate change: threshold for dangerous warming will likely be crossed between 2027-2042
The threshold for dangerous global warming will likely be crossed between 2027 and 2042 - a much narrower window than the Intergovernmental Panel on Climate Change's estimate of between now and 2052. In a study published in Climate Dynamics , researchers from McGill University introduce a new and more precise way to project the Earth's temperature.

A step toward understanding why COVID-19 boosts stroke risk
A UCLA-led study may help explain how COVID-19 increases the risk for stroke. Scientists made the finding by running fluid spiked with a COVID-19-like protein through a 3D-printed model of the arteries of a patient who had suffered a stroke. Although COVID-19 was first identified by its severe respiratory symptoms, the virus has caused strokes in young people who had no known risk factors.

Survey says: Canadians asking for better food systems and food sparked by COVID-19 access
Shopping anxiety, higher food prices and individual income limitations are some of the factors making access to food challenging for Canadians during the COVID-19 pandemic, a new study suggests. Researchers conducted an online inter-provincial survey with residents of B.C. Alberta, Ontario, Quebec and the Atlantic provinces during the first wave of COVID-19.

Coral reefs serve important ecological functions, from providing habitat for countless species to protecting shorelines from erosion. Reef-dependent fisheries are also a vital source of food and income for hundreds of millions of people in tropical island nations where coral reefs are valued at $6.8 billion annually.
Artificial Intelligence Classifies Supernova Explosions with Unprecedented Accuracy
Artificial intelligence is classifying real supernova explosions without the traditional use of spectra, thanks to a team of astronomers at the Center for Astrophysics Harvard & Smithsonian. The complete data sets and resulting classifications are publicly available for open use. By training a machine learning model to categorize supernovae based on their visible characteristics, the astronomers were able to classify real data from the Pan-STARRS1 Medium Deep Survey for 2,315 supernovae with an accuracy rate of 82-percent without the use of spectra.

How to power up battery manufacturing in India
India will need to make the switch from coal to renewable energy to meet its ambitious decarbonization goals. Batteries could be key to meeting these targets and represent an opportunity to develop the country's battery manufacturing industry. India is one of only a few countries whose national emissions reduction target is in line with the Paris Agreement's goal of reducing global warming before Earth's temperature reaches a dangerous threshold.

The mystery surrounding the whereabouts of a supermassive black hole has deepened. Despite searching with NASA's Chandra X-ray Observatory and Hubble Space Telescope, astronomers have no evidence that a distant black hole estimated to weigh between 3 billion and 100 billion times the mass of the sun is anywhere to be found.
How does immersive reality affect implicit racial bias?
In the new experiment, 92 white female participants stood in a virtual street embodied either in a white or black body, with crowds of virtual people walking by. For those who experienced the neutral or positive crowd the same results as previously found were replicated and the implicit racial bias of those in the black body decreased.

Study: Deep learning microscope images thick tissues with extended depth-of-field When surgeons remove cancer, one of the first questions is, "Did they get it all?” Researchers from Rice University and the University of Texas MD Anderson Cancer Center have created a new microscope that can quickly and inexpensively image large tissue sections, potentially during surgery, to find the answer.

New study links cadmium to more severe flu, pneumonia infections
High levels of cadmium, a chemical found in cigarettes and in contaminated vegetables, are associated with higher death rates in patients with influenza or pneumonia-and may increase the severity of COVID-19 and other respiratory viruses, according to a new study. "Our study suggests the public in general, both smokers and nonsmokers, could benefit from reduced exposure to cadmium,” said lead author Sung Kyun Park, associate professor of epidemiology and environmental health sciences at the University of Michigan School of Public Health.
