Most male birds try to attract mates with elegant gestures. Seabirds bob their heads and flutter their wings, while peacocks fan out their beautiful feathers. However, the white bellbird, endemic to the Amazon rainforest in Brazil, dispenses with the pleasantries and cut to the chase by shrieking in its prospective "date's" face at a deafening 125 decibels (Db)— the loudest bird call ever recorded. To put it in perspective, that is 40 Db higher than the safe hearing range for humans! Prior to this, the honor belonged to another Amazon-dweller — the aptly-named screaming piha — which has a peak recorded "song" volume of 116 Db.
On Monday, November 11, 2019, stargazers will be treated to an unusual sight: our solar system's smallest planet, Mercury, passing between the Earth and the Sun. The rare event, called a transit, will be the fourth of just 14 transits of Mercury that will occur during the 21st century. The last one took place on May 8, 2016, and the next will not occur until November 13, 2032. However, it will not be visible from North America, which means the continent's residents will have to wait until May 7, 2049, to observe the celestial delight again.
Looking for something spookier than your neighborhood haunted house this Halloween? Then you may want to take a peek at some of the ghostly space images NASA scientists have been able to capture through various missions, like the Hubble Space Telescope and the Spitzer Space Telescope.
On Sunday, November 3, 2019, most North Americans will mark the end of Daylight Saving Time (DST) by moving their clocks back an hour. This simple action will not only add an extra 60 minutes to their weekend, but also shift daylight back into the morning hours, making it a little less painful to wake up for school and work during the shorter winter days.
Humpback whales spend summers feeding in the cold Arctic and Antarctic waters and then migrate to tropical waters during the winters to breed and give birth. Since they don't eat at all during this time, the mammals have to ensure they have enough fat reserves to feed their calves and to sustain themselves. To optimize their prey consumption, humpback whales often create circular "nets" with bubbles exhaled from their blowholes. Now, for the first time, researchers have captured detailed footage of the so-called bubble-net fishing technique from the whale’s point of view along with, an aerial video.
Kenya's Eliud Kipchoge has been dominating the world marathon stage since winning the Chicago Marathon in 2014. In the years following, the elite runner has won every marathon he has participated in, including the gold medal at the 2016 Summer Olympics. In 2018, Kipchoge made history when he crossed the finish line of the Berlin Marathon in 2:01:39, crushing the existing men's world record by a minute and 18 seconds. On October 12, 2019, the 34-year-old further cemented his legacy by running the 26.2 miles in Vienna, Austria in less than two hours, faster than any other person in history. His time of 1:59:40 required him to maintain an average pace of about 4:35 per mile!
Japan, which gets hit by an average of three typhoons annually, is no stranger to the powerful tropical storms. However, Typhoon Hagibis, which made landfall in the Shizuoka Prefecture at about 7:00 pm local time on October 12, 2019, is the worst storm experienced by the island nation in almost 60 years. Dropping as much as 35 inches of rain in some areas, it caused massive landslides, flooded rivers, and damaged homes and businesses in eight of Japan's 47 prefectures.
Though not as mainstream as devices like smartphones and fitness trackers, more companies are now experimenting with the concept of connected garments. Among the pioneers is London-based CuteCircuit, which has been creating fashionable smart clothing since 2004. The company's latest innovation is the "Sound Shirt," which allows deaf people to "feel" live music by transforming the tunes into touch sensations in real time.
