Thanks to 20 years of homegrown galactic data, astronomers at the University of Wisconsin–Madison, UW–Whitewater and Embry-Riddle Aeronautical University have finally figured out just how much energy permeates the center of the Milky Way. The researchers say it could one day help astronomers track down where all that energy comes from. Understanding the source of the radiation could help explain not only the nature of the Milky Way, but the countless others that resemble it.
New UCLA research conducted in mice could explain why some people suffer more extensive scarring than others after a heart attack. The study, published in the journal Cell, reveals that a protein known as type 5 collagen plays a critical role in regulating the size of scar tissue in the heart.
Sweden’s controversial decision not to lock down during COVID-19 produced more deaths and greater healthcare demand than seen in countries with earlier, more stringent interventions, a new analysis finds.
High-risk drinkers who substantially reduce their alcohol use can lower their risk of cardiovascular disease (CVD) despite not completely abstaining, according to study findings published in Alcoholism: Clinical and Experimental Research. CVD encompasses a range of conditions involving the heart or blood vessels, and is the leading cause of death in the US. It is also one of many negative health outcomes associated with heavy drinking and alcohol use disorder (AUD). Reductions in drinking can be defined using World Health Organization (WHO) ‘risk drinking levels’, which classify drinkers into ‘very high’, ‘high’, ‘moderate’ and ‘low’ risk categories based on their average daily alcohol consumption. Previous research has shown that a reduction of two or more levels (for example, from ‘very high’ to ‘moderate’) can lower the risk of multiple health issues, but did not assess the impact on CVD specifically. The latest study has examined associations between reductions in WHO risk drinking
Citizen science could help track progress towards all 17 UN Sustainable Development Goals (SDGs). An IIASA-led study, for the first time, comprehensively analyzed the current and potential contribution of citizen science data to monitor the SDGs at the indicator level.
An international team of scientists from Austria, Germany and Ukraine has found a new superconducting system in which magnetic flux quanta can move at velocities of 10-15 km/s. This opens access to investigations of the rich physics of non-equilibrium collective systems and renders a direct-write Nb-C superconductor as a candidate material for single-photon detectors.
Scientists discovered that histones act as an enzyme that converts copper into a form that can be used by the cells. The finding refutes earlier theories that copper spontaneously converts in the body into a usable state.

Intrigued by how reflection changes images in subtle and not-so-subtle ways, a team of Cornell University researchers used artificial intelligence to investigate what sets originals apart from their reflections. Their algorithms learned to pick up on unexpected clues such as hair parts, gaze direction and, surprisingly, beards – findings with implications for training machine learning models and detecting faked images.
Geoscientists at The University of Texas at Dallas recently used supercomputers to analyze massive amounts of earthquake data to generate high-resolution, 3D images of the dynamic geological processes taking place far below the Earth’s surface.
New research from The University of Texas at Dallas suggests food deserts might be more prevalent in the U.S. than the numbers reported in government estimates.
Studies have shown the Arctic is warming roughly twice as fast as the rest of the world, and its soil holds twice the amount of carbon dioxide as the atmosphere. New research from San Diego State University finds that water from spring snowmelt infiltrates the soil and triggers fresh carbon dioxide production at higher rates than previously assumed.
New research from The University of Queensland has found that women who have hot flushes and night sweats after menopause are 70 per cent more likely to have heart attacks, angina and strokes.
In a newly published experimental study, the consumption of dietary fibre from oat and rye brans supported the growth of beneficial gut microbiota, which in turn ameliorated cholesterol metabolism, enhanced gut barrier function and reduced hepatic inflammation.
Neuroscientists reveal for the first time how relationships between different odors are encoded in the brain. Findings may explain why individuals have common but highly personalized experiences with smell, and inform efforts to understand how odor chemistry is translated into perception.
For the first time, scientists have shown that the bacterium that causes the tick-borne disease anaplasmosis interferes with tick gene expression for its survival inside cells and to spread to a new vertebrate host.
The environmental benefits of taller, shrubbier tundra plants in the Arctic may be overstated, according to new research involving the University of Stirling.
Research from the University of Kent has found that people who adopt a collectivist mindset are more likely to comply with social distancing and hygiene practices to help reduce the spread of COVID-19.
Glass- and carbon- fiber reinforced composites, whose use in aerospace and other high-performance applications is soaring. Components made of these materials are often 3D printed. Their strength and flexibility depends on how each layer of fibers is deposited by the printer head, whose layer-by-layer orientation is determined by toolpath instricutions in a component's CAD file. A team of NYU Tandon researchers showed that that 3D printing toolpaths are easy to reproduce — and therefore steal — with machine learning. They demonstrated a method of reverse engineering of a 3D-printed glass fiber reinforced polymer filament that, when 3D-printed, has a dimensional accuracy within one-third of 1% of the original part.
Incarceration and police discrimination may contribute to HIV, depression and anxiety among Black gay, bisexual and other sexual minority men, a Rutgers led study finds.

University of Wisconsin–Madison researchers have developed a safer and more efficient way to deliver a promising new method for treating cancer and liver disorders and for vaccination — including a COVID-19 vaccine from Moderna Therapeutics that has advanced to clinical trials with humans.
University of Wisconsin–Madison engineers have made it possible to remotely determine the temperature beneath the surface of certain materials using a new technique they call depth thermography. The method may be useful in applications where traditional temperature probes won’t work, like monitoring semiconductor performance or next-generation nuclear reactors.
Research out today in the journal Cell shows that a specific change in the SARS-CoV-2 coronavirus virus genome, previously associated with increased viral transmission and the spread of COVID-19, is more infectious in cell culture.
Two variants of the novel coronavirus (SARS-CoV-2), called G614 and D614, were circulating in mid-March. A new study shows that the G version of the virus has come to dominate cases around the world. They report that this mutation does not make the virus more deadly, but it does help the virus copy itself, resulting in a higher viral load, or "titer," in patients.
A new research study provides possible explanations for COVID-19 patients who present with extremely low, otherwise life-threatening levels of oxygen, but no signs of dyspnea (difficulty breathing). This new understanding of the condition, known as silent hypoxemia or “happy hypoxia,” could prevent unnecessary intubation and ventilation in patients during the current and expected second wave of coronavirus.
Teleportation is most commonly the stuff of science fiction and, for many, would conjure up the immortal phrase "Beam me up Scotty".
