Scientists are working on new ways to fight COVID-19. They are making changes to a special molecule called N, N'-diphenylurea. This molecule can stop the virus from making copies of itself. But it has some problems. It doesn't dissolve well in water and can be harmful to cells. So, they made 27 new
Scientists have found a clever way to link peptides and small proteins together. They used special molecules called polyvalent thioesters as anchors. These anchors have many arms, like a star, and can hold multiple peptides or proteins. The process is quite neat. First, they attached several peptid
Las Vegas is back on track, or so says the boss of Caesars Entertainment. Thomas Reeg, the CEO, noticed a pickup in visitors during the last part of the year. This is after a slower summer season. He thinks this trend will keep going into the early months of the next year. What's causing this comeb
In the early days of the COVID-19 pandemic, doctors noticed something odd. Many patients fighting the virus also had fungal infections. These fungi, mainly from the Candida family, were found in the lungs and airways of COVID-19 patients more often than in those who didn't have the virus. Researche
Vaccines are like training camps for your immune system. They help your body get ready to fight off viruses. But there is more to it than just building general defenses. Scientists are still figuring out how vaccines affect the body's first line of defense, which is in your nose and throat. The COV
The human body is a bustling city of tiny organisms. Some of these tiny organisms are bacteria that live in the upper respiratory tract. These bacteria can influence how the body reacts to infections like COVID-19. A recent study shed light on this complex relationship. Researchers looked at 123 pe
Tuberculosis (TB) and COVID-19 are both nasty lung infections. They can cause a lot of damage to the lungs. Scientists wanted to see what happens when someone has both infections at the same time. They used a special type of lung cell, called A549 cells, to study this. First, they infected the cell
The COVID-19 pandemic is still a major issue in 2025. The virus, SARS-CoV-2, changes rapidly. This makes it hard for vaccines and medicines to work well. Different versions of the virus cause different levels of sickness. Scientists are not sure why this happens. A new study looks at how different
The world of vaccines and immunity is full of surprises. One big surprise came from a study that looked at how past infections and vaccines work together. The study focused on people who had already had COVID-19 and then got vaccinated. The findings were not what many expected. The study fou
The ability to spot tiny changes in DNA, known as single nucleotide variations, is crucial. These changes can signal serious illnesses, help identify pathogens, or predict how well a treatment will work. Think about the COVID-19 virus. It has many variants, like D614G and N501Y, which can make the v
