Thermoset plastics are ones that contain polymers that cross-link together during the curing process to form an irreversible chemical bond.  This improves the material’s mechanical properties, provides chemical resistance, heat resistance, and structural integrity.  Thermosets include epoxies, polyurethanes, and rubber used for tires.  The big problem with thermosets is that they cannot be easily recycled […]

The numbers are in and, unsurprisingly, July was a hot month.  July 2020 tied for the second-hottest July on record for the planet, according to the National Oceanic and Atmospheric Administration.  In our own backyard, the Northern Hemisphere saw the hottest July ever, breaking the previous record set just last year. The July 2020 global […]

About 10% of all electricity consumption in the U.S. is devoted to keeping us cool with air conditioning and other methods.  Researchers at two universities in Shanghai, China have developed a new material that can be made into clothing that cools the wearer without using any electricity. The new fabric transfers heat, allows moisture to […]

Siberia has been in the news for record-setting heat waves and wildfires, but it is not the only northern region experiencing unusual weather.   Alaska, apart from setting its own warm weather records, is experiencing the rainiest five years in its century-long meteorological record. Extreme weather in the Arctic is being driven by an aspect of […]

There have been recent news stories about giant jellyfish washing ashore from Maine to the south coast of Massachusetts.  These stories have claimed that some of these lion’s mane jellyfish have been the largest on record and even might be the largest animals in the ocean. The truth of these accounts is rather suspect.  For […]

At last a good news story about what we eat, or more specifically, about what we like to eat.   According to research published recently in the European Journal of Preventive Cardiology, eating chocolate at least once a week is linked with a reduced risk of heart disease. In the past, clinical studies have shown that […]

Electronic devices get smaller and smaller all the time.  We are used to carrying around phones in our pockets that incorporate a whole host of sophisticated devices. But we can still be amazed by miniaturization.  Recently, scientists at the University of Washington announced the development of a tiny, wireless camera small enough to be worn […]

Carbon dioxide emissions by electricity generating plants, fossil-fuel burning vehicles, and industry produce about 2/3 of the greenhouse gases driving climate change.  Without decreasing these emissions, the earth will continue to get warmer, sea levels will continue to rise, and the world will face more droughts, floods, wildfires, famine and conflict. Electrification of vehicles and […]

A research team led by scientists at UCLA have developed a super-white paint that reflects as much as 98% of incoming heat from the sun.  Such paint, if used on rooftops and other parts of buildings, could have a major impact on reducing the costs of keeping buildings cool. Passive daytime radiative cooling is a […]

In late July, the two houses of the New York legislature passed a number of environmental bills covering a wide range of topics. These included a bill to add protected status for streams that support fisheries and non-contact recreation.  A second bill bans the use of PFAS in food packaging.  A third bill classifies all […]

The domestication of cows, pigs, chickens, and other animals as livestock for their meat, milk, and eggs was historically revolutionary.  It boosted food security by giving people a readily-available means of feeding themselves as opposed to more traditional methods such as hunting and fishing.  But animal agriculture has plenty of drawbacks.  The industrialization of animal […]

Major automakers as well as dedicated specialized companies are actively developing autonomous vehicle technology.  Many cars already offer varying degrees of self-driving capability.  These vehicles have a variety of sensor systems that allow them to detect other objects on the road.  Many rely on lidar or on cameras using visible or near-infrared light and these […]

Last year, we talked about the troubles facing the Colorado River.  Nearly two decades of drought conditions have reduced the water levels of the two largest reservoirs of Colorado River water and have threatened the water supply of millions of people in the region.  Clear scientific evidence shows that climate change is constricting the iconic […]

The California condor is the largest North American land bird.  Its wingspan is nearly 10 feet and its weight of up to 26 pounds nearly equals that of the trumpet swan, the heaviest native North American bird.  California condors can live up to 60 years, making them among the world’s longest-living birds as well.  But […]

PFAS, short for poly and perfluoroalkyl substances, have been used in commercial products since the 1940s.  There are more than 4,000 different chemicals in the class.   Some of the most commonly used PFAS chemicals, like PFOS and PFOA, have long half-lives, which has earned them the moniker “forever chemicals.”  These dangerous chemicals have not been […]
