Fitbit's latest app update, now in public preview, brings a mix of improvements and letdowns. The AI coach, in particular, had a rocky start. On day one, it had trouble recognizing the Pixel Watch 4, confusing it with the older Pixel Watch 2. However, some fixes rolled in over the week, like better
Scientists have found a clever way to make solar hydrogen production more efficient. They created a special photoanode using indium oxide and selenium. This combo boosts the photoanode's ability to capture and use sunlight. The selenium in the photoanode creates tiny flaws, called oxygen vacancies.
Scientists have been puzzling over how to tell male dinosaurs from females for ages. Now, a fresh study from a team in Northern Ireland might have found a clue hidden in some unexpected places: healed fractures in dinosaur tails. These injuries could be the result of rough mating, where male dinosau
Scientists have been experimenting with different materials to help bones heal better. They've created a new type of material that combines calcium phosphate with tiny amounts of sodium, magnesium, and zinc. This mix is then heated to a high temperature to make it strong. They also added a ceramic
Scientists have found a way to make better electrolytes for lithium-ion batteries. These electrolytes help batteries work well, even in cold weather. They used computer simulations and AI to test 2604 different electrolyte recipes. The team found that some electrolytes work really well at room temp
Scientists have found a way to make light sensors work better by adding a special material to them. These sensors are used in things like communication and smart devices. The problem was that they weren't very good at detecting light in dark places or pinpointing where the light was coming from. But
Scientists have created a new tool to measure acidity in water. This tool is better than old ones. It uses a special gel and a smart probe. The probe has two parts that change when acidity changes. This makes the tool very accurate. Old tools had problems. They were not very accurate. They could be
First responders see a lot of intense situations. They handle emergencies and care for very sick people. This job can be really hard on their minds. It’s easy to see why they might develop mental health issues, like posttraumatic stress disorder (PTSD). People deal with stress in different ways. So
Sci-fi TV shows have changed a lot over the years. Many popular series from the past wouldn't make it today. Why? Because making TV shows is different now. Networks and streaming services are picky about what they spend money on. Take "The Expanse, " for example. It was a big hit and had a huge bud
Scientists have been on the hunt for better ways to fight cancer. They've found that a protein called HDAC1 plays a big role in how cancer grows. This protein is like a switch that can turn genes on and off. By targeting HDAC1, researchers hope to develop new drugs that can stop cancer in its tracks
