During the past 70 years, global shark populations have been on the decline.   Many species have become threatened or endangered.  Conservation efforts have been underway in many places, but shark populations continue to be at risk because of over-fishing and habitat loss. A comprehensive study by marine biologists at Texas A&M University deployed more than […]

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 […]

Scientists have been sounding the alarm on the global struggle of pollinators for many years.  According to a United Nations-sponsored report, 40% of invertebrate pollinator species, including bees and butterflies, are facing extinction.  Approximately 80% of all flowering plant species, which are responsible for 35% of global food production, depend on pollination.  According to new […]
