Three years ago, as part of the public health messaging in response to the COVID-19 pandemic, the World Health Organization launched the "Wear A Mask" campaign on social media. However, despite their benefits to public health, mask-wearing quickly became a highly politicized and divisive issue across the globe. But the campaign gained impressive traction after World Health Organization Director-General Tedros Adhanom Ghebreyesus issued the following tweet on X, the social media platform known at the time as Twitter, on August 21, 2020, thanking BTS, a South Korean K-pop group, for supporting the mask-wearing public ...

In art, the negative space in a painting can be just as important as the painting itself. Something similar is true in insulating materials, where the empty spaces left behind by missing electrons play a crucial role in determining the material's properties. When a negatively charged electron is excited by light, it leaves behind a positive hole. Because the hole and the electron are oppositely charged, they are attracted to each other and form a bond. The resulting pair, which is short lived, is known as an exciton [pronounced exit-tawn].    Excitons are a key part of many technologies, including solar panels, photodetectors and sensors, as well as light-emitting ...

They’re being hailed as an effective way to lose weight, but diabetes drugs like Ozempic may come with a heightened risk of severe gastrointestinal problems. That’s according to new research from the University of British Columbia showing that medications known as GLP-1 agonists—which includes brands like Wegovy, Ozempic, Rybelsus and Saxenda—are associated with an increased risk of serious medical conditions including stomach paralysis, pancreatitis and bowel obstruction. While previous studies highlighted some of these risks in patients with diabetes, this is the first large, population-level study to examine adverse gastrointestinal ...

When the new SARS-CoV-2 virus began killing thousands of people every week, physicians and scientists around the globe raced to learn why the new pathogen was so deadly. Among many early findings, experts noted that the infection played havoc with blood circulation, both inflaming the linings of blood vessels and making the blood itself more likely to form dangerous clots. Critically ill COVID-19 patients suffered pulmonary embolisms, deep vein thrombosis (DVT), arterial thrombosis, as well as microvascular thrombosis affecting tissues of the lungs, kidneys, and heart. Doctors tried a wide array of existing medications in hopes of controlling the blood system impacts, with mixed ...

New research has shed light on how genetics influences the growth of the placenta, revealing a link to risk of disease in the mother.

Creating artificial life is a recurring theme in both science and popular literature, where it conjures images of creeping slime creatures with malevolent intentions or super-cute designer pets. At the same time, the question arises: What role should artificial life play in our environment here on Earth, where all life forms are created by nature and have their own place and purpose? Associate professor Chenguang Lou from the Department of Physics, Chemistry, and Pharmacy, University of Southern Denmark, together with Professor Hanbin Mao from Kent State University, is the parent of a special artificial hybrid molecule that could lead to ...

Scientists using the H.E.S.S. observatory in Namibia have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy of visible light. This observation is hard to reconcile with the theory of the production of such pulsed gamma rays, as the international team reports in the journal Nature Astronomy. Pulsars are the left-over corpses of stars that spectacularly exploded in a supernova. The explosions leave behind ...
