A low-cost passive cooling technology made from a polymer film could be used to passively cool buildings in metropolitan areas, avoiding the need for electricity.
Modern air conditioning systems consume significant amounts of energy to cool buildings during the daytime, generating significant amounts of greenhouse gases responsible for climate change!

For example, air conditioning accounts for around 15 percent of total primary energy consumption in the United States and can be as high as 70 percent in extremely hot countries like Saudi Arabia.
Technologies that use radiative cooling to control the temperature of buildings, such as planar multilayered photonic films and hybrid metamaterial films, are attracting considerable attention because they do not use electricity; however, they are complicated and costly to manufacture.
Big dinosaurs kept cool thanks to blood vessels in their heads | Science News
Massive dinosaurs came in many different forms, but they all had the same problem: Staying cool. Now, fossilized traces of blood vessels in the skulls of big-bodied dinosaurs reveal how different dinos avoided heatstroke! Popular Science Radio - Home | ERNLive.com www.ernlive.com/show/ ...radio/57 POPULAR SCIENCE RADIO brings you all the newest discoveries and emerging technologies, cutting-edge innovations in science and technology each week. Presented in an interactive, entertaining and easy to understand forum with host, Alan Taylor.!! Long-necked sauropods may have panted to stay cool, for example, while heavily armored ankylosaurs relied on elaborate nasal passages.
Chemical analyses of fossil sauropod teeth previously suggested that, despite their massive bodies, the animals maintained body temperatures similar to those of modern mammals ( SN: 6/23/11 ). One possible explanation for this was thermoregulation, in which blood vessels radiate excess heat, often with the help of evaporative cooling in moist parts of the body, such as the nose and mouth.
To assess how giant dinosaurs might have used thermoregulation, two vertebrate paleontologists from the Ohio Center for Ecology and Evolutionary Studies in Athens mapped blood vessel networks within fossil dinosaur skulls and skulls from dinosaurs' modern relatives, birds and reptiles!

The weirdest idea in quantum physics is catching on: There may be endless worlds with countless
Ever wonder what would have happened if you'd taken up the "Hey, let's get coffee" offer from that cool classmate you once had? If you believe some of today's top physicists, such questions are more than idle what-ifs. Maybe a version of you in another world did go on that date, and is now celebrating your 10th wedding anniversary.
But according to an increasingly popular analysis of quantum mechanics known as the " many worlds interpretation ," every fundamental event that has multiple possible outcomes — whether it's a particle of light hitting Mars or a molecule in the flame bouncing off your teapot — splits the world into alternate realities.
Even to seasoned scientists, it's odd to think that the universe splits apart depending on whether a molecule bounces this way or that way. It's odder still to realize that a similar splitting could occur for every interaction taking place in the quantum world .

Algae inside blood vessels could act as oxygen factories | Science News
Using algae as local oxygen factories in the brain might one day lead to therapies for strokes or other damage from too little oxygen, researchers from Ludwig-Maximilians University Munich said October 21 at the annual meeting of the Society for Neuroscience.
"In the beginning, it sounds really funny," says neurobiologist Suzan Özugur. "But it works, so why not? I think it has great potential." Even more futuristic possibilities include using algae in the veins of astronauts on long-haul space missions, says neurobiologist Hans Straka.
Straka, Özugur and their colleagues had been bubbling oxygen into severed tadpole heads to keep nerve cells active. But in talks with botanists, Straka got the idea to use algae instead. "I wouldn't call it crazy, but unconventional, let's say."
The researchers injected either green algae ( Chlamydomonas reinhardtii ) or cyanobacteria ( Synechocystis ) into tadpoles' blood vessels, creating an eerie greenish animal. Both algae species make oxygen in response to light shining through the tadpoles' translucent bodies.
Twist-based refrigeration: Twisting and coiling 'twistocaloric' yarns to keep cool -- ScienceDaily
An international team led by researchers at The University of Texas at Dallas and Nankai University in China has discovered a new technology for refrigeration that is based on twisting and untwisting fibers.
In research published in the Oct. 11 issue of the journal Science , they demonstrated twist-based refrigeration using materials as diverse as natural rubber, ordinary fishing line and nickel titanium wire.
"Our group has demonstrated what we call 'twistocaloric cooling' by changing the twist in fibers. We call coolers that use twist changes for refrigeration 'twist fridges,'" said Dr. Ray Baughman, director of the Alan G. MacDiarmid NanoTech Institute at UT Dallas. Baughman is a corresponding author of the study, along with Dr. Zunfeng Liu, a professor in the State Key Lab of Medicinal Chemical Biology in the College of Pharmacy at Nankai University in Tianjin.
