Igor's Lab recently posted an in-depth overview of Nvidia's estimated production and development schedule (opens in new tab) for its new RTX 40-series GPUs. In it, he throws some cold water on the hot rumors of an impending Nvidia launch, suggesting those won't be joining the best graphics cards as soon as we might like. The current rumors surrounding the RTX 40-series are incredibly vague and have very little concrete data, other than the information that was leaked via the LAPSU$ hack earlier this year.Igor's take,…

During hot months, urban regions with concentrated concrete buildings, pavements and surfaces can experience extreme temperatures. Much of it is due to the heat island effect that gets aggravated due to the modern urban designs and techniques. These buildings trap and retain heat, and later emit them, causing neighbourhoods to reach extremely high temperatures as compared to city outskirts. Recently, a research team has developed a method of modelling urban building energy that takes into consideration heat waves and how…

Over the past couple of years, disposable face masks have become a very plentiful form of garbage. There may actually be a use for them, however, as recent research shows that they could strengthen concrete when added to it.Previous studies have indicated that concrete is less prone to crack when tiny reinforcing fibers are mixed into it before it's poured. With that fact in mind, scientists at Washington State University wondered if the polypropylene or polyester fabric in discarded face masks could be a source of those…

Concrete is a very popular building material, enough so that one of its key ingredients – sand – is in increasingly short supply. Scientists are thus now exploring the possibility of replacing that sand with glass waste that would otherwise end up in landfills.Although glass is considered a recyclable material, it quite often doesn't get recycled. This may be due to a lack of properly equipped recycling facilities, or the fact that glass waste frequently takes the form of numerous fragments that are too small to sort by…
