Augmented reality (AR) and virtual reality (VR) are already changing the way we learn, work, and play. But what if these technologies could be even better? Enter tunable holographic metasurfaces. These tiny structures can manipulate light in ways that could revolutionize AR and VR devices. Right now, AR and VR have some limitations. They can be bulky, expensive, and...
In the complex world of cancer, tiny molecules can have big impacts. One such molecule, tetracosatetraenoic acid (C24:4 (n-6)), has been found to play a significant role in the spread of triple-negative breast cancer (TNBC) to the lungs. This molecule is produced by an enzyme called PLA2G16, which is found in tumor cells. PLA2G16 breaks down phospholipids to create f...
In the world of veterinary medicine, some cases stand out due to their rarity. Two such cases involved dogs with a type of cancer called endometrial carcinoma, which is not very common in dogs. This cancer started in the uterus and then spread to other parts of the body, including the brain. The first dog was a 7-year-old mixed breed. It had bloody discharge from its...
Papillary thyroid cancer, or PTC, is a common type of thyroid cancer. Most people with PTC live for at least 10 years after treatment. But sometimes, the cancer can come back. This is called recurrence. It happens in about 4. 3% to 35% of cases. When PTC comes back, it often spreads to nearby lymph nodes. But it can also spread to other parts of the body. This is ca...
Ever wondered how tiny structures can do big things? Well, scientists have found a way to use tiny glass patterns, called dielectric metasurfaces, to detect changes in their environment. These patterns are so small that they can't be seen with the naked eye, but they can do something amazing: they can change how light passes through them based on what's around them. ...
Meta's push into the metaverse is costing a fortune, but is it worth it? The company's Reality Labs division lost a staggering $4. 4 billion in the third quarter alone. That's a lot of money, but it's not all bad news. The division also brought in $470 million in sales, which is more than expected. So, while Meta is spending big, it's also making some money. The Rea...
Liver surgery is a common treatment for cancer that has spread from the colon or rectum to the liver. However, even after surgery, many patients see the cancer return within two years. This is a big deal because catching it early can make a huge difference in survival rates. Researchers wanted to understand when and how this cancer tends to come back. They looked at...
Lung cancer is a tough opponent, especially when it spreads to the brain. The blood-brain barrier, a protective shield, often stops treatments from reaching brain tumors. Osimertinib, a drug used to treat a specific type of lung cancer, can cross this barrier. However, some cancer cells develop resistance to it. This is where a new player, compound D18, steps in. D1...
Topology and physics have joined forces in the past ten years. They have uncovered many new things. One big discovery is topological insulators. These are materials that let electricity flow freely on their edges but not inside. This happens because of how the material is built at a tiny level. Another cool thing is twistronics. This is when scientists twist layers ...
Scientists have found a protein that might help spot aggressive cancers early. This protein, called SAS-6, helps cells get ready to divide. But it also seems to play a role in how cancer spreads. Researchers from Brunel University of London discovered that high levels of SAS-6 make cells grow more and longer cilia. These are tiny antennae on cells that sense their su...
