Ductless mini-split air-conditioners have risen in popularity dramatically in recent years. One study now pegs their domestic market share at more than 40 percent compared to larger-scale HVAC units—and the smaller systems are even more popular in Asia and Europe than in the US.Mini-splits make a compelling climate control solution for a number of reasons. They are much smaller and easier to install than HVAC systems, they’re far less expensive, and they’re quiet. Many are sold at big-box stores and online, and enterprising DIYers can certainly install one without professional help, provided they have the required electrical connections. (Some mini-splits…
Most cat owners are familiar with the funny head shake their pets do, often after eating, drinking or enjoying a nice cheek scratch — they flick their head back and forth a mile a minute. Dogs and other mammals are known to show similar behaviors.So why do our furry friends shake like this, and does it mean something is wrong?Usually, this head shaking is totally normal, experts told Live Science. However, the reasons for it can vary a bit between cats and dogs. You may like Why cats shake their heads Sign up for our newsletter! (Image credit: Marilyn Perkins…
A blow-up chair? Ikea has been here before. It attempted to make inflatable furniture in the mid-1990s, when designer Jan Dranger came to the Swedish company with a revolutionary idea to solve one of its biggest challenges: how to squish sofas into its preferred flat-pack format, simplifying transport and cutting costs.It sounded like the perfect solution. Made from durable and recyclable polyolefin plastic, the chair and sofa designs could be inflated at home using only a hair dryer. Transport volumes would be cut by as much as 90 percent. Sadly, only after the “a.i.r” collection launched in the 2000 catalogue…

The alleged shooter at last night’s White House Correspondents’ Dinner in Washington DC has been named as Cole Tomas Allen, a teacher, Caltech graduate, and independent games developer. Arrested at the scene, Allen was carrying two guns and multiple knives, with the presumed intent of harming president Trump. No one was seriously hurt, although one security agent was shot at close range, saved by a bulletproof vest. At 8:35 p.m. ET, Cole Tomas Allen is alleged to have fired shorts at the Washington Hilton as he attempted to enter the annual White House Correspondents’ Dinner event. The attendants, largely made…

For sweat bees, humidity changes their already vibrant colors. According to research recently published in the journal Biology Letters, moisture in the air makes the bees go from blue to green. “When people think of bees, they often picture drab, brown honey bees,” Dr. Madeleine Ostwald, a study co-author and behavioral ecologist at Queen Mary University of London, said in a statement. “In reality, bees are incredibly diverse and colourful—and we’re only just…

This typically means that most excavations center on hard evidence including structural remains, pottery, weapons, or metalwork. Occasionally, researchers discover something softer that’s been preserved for thousands of years despite the odds. In Switzerland, archaeologists recently identified what may be an especially rare find. While clearing the grounds of an upcoming residential development about 20 miles northeast of Zurich, specialists at the Aargau Cantonal Archaeology service found what they believe…

After over 15 years of research, a team of scientists from the Royal Melbourne Institute of Technology in Australia and biotechnology company Snoretox have created a new treatment they say can ease breathing in flat-faced dogs. Called Snoretox-1, the new injectable treatment uses a modified version of tetanus toxin. It is placed directly into the dog’s geniohyoid muscle—in the inside of the mouth, on top of the throat area. Snoretox-1 works…

As only the third interstellar object ever detected in our solar system, it offered researchers a rare—and brief—opportunity. With the right timing and equipment, scientists around the world could examine a cosmic visitor who possibly formed under far different conditions than those experienced in our own region of the galaxy. 3I/ATLAS is now sailing away from Earth and our solar system itself, but astronomers have already learned a…
