Summer 2020 has been exciting for stargazers. They have been treated to a once-in-a-lifetime visit from comet NEOWISE and had the rare opportunity to observe five planets and a full moon simultaneously, among other celestial events. Now, to top it all off, come the Perseids — the biggest and most spectacular meteor showers of the year....
Read news articleMale birds typically sing the same tunes as the rest of their species because an unrecognizable song defeats the two primary reasons for their crooning — to establish and defend their territory and to attract mates. While the songs, which are passed down from generation to generation, may vary slightly by region, any new compositions are typically limited to the local environment. However, for reasons unknown to scientists, white-throated sparrows across Canada are abandoning their classic song for a catchy new tune "written" by their peers in British Columbia....
Read news articleScattered across the ocean bed, and often hidden from the human eye, are hundreds, or perhaps even thousands, of "blue holes." The massive underwater sinkholes, which host a diverse biological community — ranging from coral to sponges to sharks to sea turtles — were formed thousands of years ago when groundwater dissolved karst, a type of porous limestone rock found on ocean floors....
Read news articleOver the years, there have been numerous attempts to create "glow-in-the-dark" plants. However, none of the approaches — which included infusing plants with nanoparticles of the luciferins and enzymes needed for the phenomenon to occur, or incorporating them with bacterial bioluminescence genes – proved feasible....
Read news articleEven those not normally interested in astronomy will find it hard to resist NEOWISE, the brightest comet to grace our skies since the 1997 appearance of Comet Hale-Bopp. The spectacular cosmic snowball of frozen gas, rock, and dust has been visible to those willing to wake up before dawn since early July. However, it has now risen high in the evening skies and can be viewed with the unaided eye by even the most casual stargazer....
Read news articleThe solar system is about to get busy! In the next few weeks, a slew of spacecraft will embark on a one-way journey to Mars, to seek evidence of past life and to further investigate its unusual atmosphere. The back-to-back missions are timed to take advantage of the short window of opportunity — caused by celestial mechanics — that will allow them to reach the Red Planet in the most efficient and cost-effective manner....
Read news articleThe term "bird brain" is frequently used to describe a person's lack of intelligence and good decision-making ability. However, some scientists believe it should be considered a compliment, given that many birds can perform tasks that were once considered solely within the realm of humans. These include manufacturing and using tools, solving problems, and planning for future needs. Now, Griffin, an African Grey parrot, has proved that birds may even possess better visual memories than human adults and children....
Read news articleOne of the biggest challenges to battling the rapid spread of COVID-19 is identifying and isolating people who are infected before the symptoms, which usually take between 3 to 13 days to surface. Now, frontline workers may get some help from canines who can "sniff out" the disease even when the patient is asymptomatic, meaning he or she never shows any of the traits associated with COVID-19....
Read news articleA massive dust cloud that had been journeying 5,000 miles from the Sahara Desert across the Atlantic Ocean since June 15, 2020, finally hit the United States mainland on June 26, 2020. Nicknamed "Godzilla," the 3,500 mile-long plume broke into two chunks, thanks to the split in the mid-levels of the atmosphere....
