A new device made from two layers of aluminum can change the way light twists, working well across a wide range of colors from green to near‑infrared. The designers did not use an idealized flat coating; instead they measured the real, uneven shape of a silica (SiO₂) layer that sits on top of the
In the world of wireless tech, a cool new idea has popped up. It's all about making antennas smarter and more efficient. This isn't just any antenna, though. It's a special kind that can handle signals in a unique way. The big deal here is that this antenna can take a straight-line signal and twist
Ever heard of tiny waves that can make big things happen? Let's talk about something cool called quasi-BIC metasurfaces. These are like tiny, special surfaces that can do amazing things with light. They have something called Fano resonances. Think of it like a secret handshake between two types of l
Colon cancer can be tricky. It often comes back in a new spot after treatment. This is called metachronous metastasis. Doctors want to find ways to predict who might face this issue. A recent study looked at patients with stage II or III colon cancer. These patients had surgery between 2016 and 202
The liver is a busy place. It does a lot of important jobs, like helping with digestion and storing energy. But it also has a sneaky side. It's a cozy spot for cancer cells to hide and grow, especially when they spread from other parts of the body. This is because the liver has a special way of keep
Meta, the company behind Facebook, Instagram, and WhatsApp, has been shaking things up with its artificial intelligence (AI) division. The big boss, Mark Zuckerberg, brought in a young tech whiz, Alexandr Wang, to lead a new team called TBD Lab. This team is made up of some of the brightest AI minds
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 no
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 i
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 fir
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
