Are you stressed? It's hard to tell just by checking your heart rate. Why? Because your heart rate changes a lot depending on what you're doing. Like when you're walking, running, or even sitting still. Scientists wanted to find a way to measure stress using heart rate, even when you're moving aroun
SpaceX has marked Saturday evening as the ideal time to launch 20 Starlink satellites into low-Earth orbit. The launch site chosen is Vandenberg Space Force Base, with a four-hour window that kicks off at 7:26 p. m. Once the first stage of the Falcon 9 rocket detaches, it’s scheduled to touch down o
Existing methods for detecting targets struggle when the lights are low. This leads to mistakes like false alarms or missed targets. Researchers have come up with a new method called DimNet to tackle this issue. DimNet makes several improvements to the current models. It combines information from di
Xylazine, often found in illegal opioids and used as a vet sedative, is a dangerous substance. It’s linked to drug crimes and health risks, even appearing in food samples. Scientists found a quick way to spot it using antibodies. They designed four new haptens, like tiny signals for the antibodies t
Imagine having a simple blood test that could catch cancer early. Scientists have been on the hunt for such a solution, and they've made a significant stride. They've discovered a way to spot early cancer by examining blood samples for tiny differences in cancer cells, called methylation patterns. T
Imagine if we could catch colon cancer early by simply analyzing breath or stool samples. Scientists are working on exactly that! They're exploring the use of volatile organic compounds (VOCs) to detect colorectal cancer (CRC) and its precursors, known as advanced adenomas. Unlike the current faecal
Ever wondered how hackers, also known as cryptojackers, manage to keep their shady dealings under the radar? They've devised a sneaky strategy called Delay-CJ. This method is cunning because it delays its actions, making it super hard to detect until it's already done its damage. But don't fret, the
Imagine a tiny detective in your water, hunting down specific metal ions. This detective is a sensor called PIN, which was created and tested by scientists. When Zn²⁺ (zinc) or Cd²⁺ (cadmium) ions show up, PIN changes color from blue to yellow, like a little warning light. It's so good at its job th
Former Brazilian president Jair Bolsonaro and his close allies are in hot water. Federal police recently accused them of plotting a rightwing coup to topple the country's democracy. This isn't your average scandal—it involves serious crimes like attempted coup, criminal organization formation, and t
You've probably heard about robots playing basketball. But did you know that these robots have trouble recognizing the ball and measuring distances? To fix this, scientists used a combination of robot operating systems and smart algorithms called IBN-YOLOv5s. They added a special module to the algor
