    Two centuries after Charles Darwin put the theory forward, a new study finally shows that birds living near the equator are more colourful.  Scientists have used artificial intelligence (AI) to identify the amount of colour in photos of over 24,000 preserved birds from the Natural History Museum's collection. Tropical birds living near the equator are roughly 30 per cent more colourful than non-tropical birds living nearer the poles, the scientists found, but they don't know exactly why. The long-held theory, first suspected by Charles Darwin and other naturalists in the 18th and 19th centuries, hasn't been proven until now, the experts say.   Research from the University of Sheffield found tropical birds living near the equator are roughly 30 per cent more colourful than non-tropical birds living nearer the poles. Pictured, a selection of colourful bird specimens preserved at the Natural History Museum Eighteenth- and nineteenth-century European naturalists such as von Alexander von Humboldt, Alfred Russel Wallace and Charles Darwin (pictured) were mesmerised by the diversity of forms, shapes and colours in the tropics  The research was led by Dr Chris Cooney...
    MIAMI (CBS Miami) — Mark your calendars, South Florida, fall begins on Wednesday, September 22nd. And although, the leaves will not be falling from our South Florida palm trees nor will the temperatures drop enough to put an end to the summer heat, the autumnal equinox is still happening at 3:21 pm EDT this coming Wednesday, two days after Monday night’s full moon also known as the ‘Harvest Moon’. READ MORE: Dueling Florida Lottery Jackpots: Mega Millions Reaches $432 Million, Powerball At $472 Million The autumnal equinox officially kicks off the fall season as soon as the sun crosses the celestial equator, which is an imaginary line extending straight out from Earth’s equator to the sun. View from space, the sun is in line with the Earth’s equator as the sun crosses from north to south on the autumnal equinox. The sun will cross from north to south of that imaginary line and the day hours will almost equal to night hours. While autumn begins in the Northern Hemisphere, the Southern Hemisphere is going into the spring season. This is...
    Published: 7 September 2021 17:26 GMT A new study has modeled the evolution of two celestial bodies based on a principle widely used by engineers in soil dynamics. Strange appearance of asteroids Determining And Ryu, Reminiscent of the geometric shape of a diamond, can be explained by a physical property of combining particles, a study says Published In the journal Granular Matter. The authors of the work note that the two celestial bodies are made up of a Garbage collection Connected together by a relatively weak gravitational force Rotate at high speeds on their own axis. So far its characteristic rhombic shape, the highest poles and the equator, has been the subject of debate among astronomers. Also, according to current models, asteroids must have a flat shape at their equator. To explain this unknown, the authors of the new publication focused their research on the principle that the pieces attached to the aforementioned asteroids receive a principle.

    Need a jolt of java to fuel your bayshore run or bike ride? Equator Coffees has made its first foray south of San Francisco and Oakland, opening a Peninsula cafe in Burlingame, near the Bay Trail. The coffeehouse started brewing this week at Burlingame Point, a complex of office towers built on 18 bayfront acres east of Highway 101. Nearby are Fisherman’s Park, San Francisco International Airport and the trail that loops through the Bay Area. Earlier this summer, Equator took up residence in another bayside property — San Francisco’s Round House, an art deco building with views of the Golden Gate Bridge. Besides pour-overs, filtered coffee, cappuccinos and cortados, Equator offers a number of signature drinks. The Habibi Latte combines steamed milk and two shots of espresso with orange blossom, cardamom, clove and vanilla syrup. For the Shakerato, two shots of espresso, heavy cream and dark brown sugar are shaken until frothy; there are chocolate and matcha variations too. Heading to SFO? The Red Eye tops filtered coffee with two shots of espresso. The Burlingame food menu features a Breakfast...
    In Hungary, F3 played the fourth weekend of the seven scheduled. Hauger and Prema dominate, while Correa advances in his recovery and Campos closes the teams’ general classification. August 4, 2021 (00:13 CET) The F3 race was the prelude to F1 in Hungary. Juan Manuel Correa emerges from the curtain of water The Formula 3 season, which has no Spanish in the running, is being dominated by the Prema team and one of its drivers, 18-year-old Norwegian Dennis Hauger. The last weekend of the four disputed so far (the championship started in Montmeló) was Prema dominance in qualifying, with Arthur Leclerc taking pole followed by the championship leader in second position. Of the three races held over the weekend, the first was won by the Italian driver from Campos, Lorenzo Colombo and it was very emotional. On the podium was Adrián Jr. who dedicated the victory to the memory of his father, however a failure to leave the distance with the safety car, caused Colombo to be sanctioned with 2 seconds falling to...
    Warm temperatures and tropical climates may really help reduce the spread of COVID-19, a new study suggests. The study found that places with warm temperatures and long hours of sunlight — such as countries close to the equator and those experiencing summer — had a lower rate of COVID-19 cases, compared with countries farther away from the equator and those experiencing colder weather. The findings held even after the researchers took into account other factors that could affect both the spread of COVID-19 and the number of reported cases, such as a country's level of urbanization and the intensity of COVID-19 testing. Still, the authors stress that their findings don't mean that summer weather will eliminate COVID-19; but it may give people a leg up against the disease. BIDEN SAYS SCHOOLS 'SHOULD PROBABLY ALL BE OPEN' IN FALL "Our results do not imply that the disease will vanish during summer or will not affect countries close to the equator," the authors wrote in their paper, published April 27 in the journal Scientific Reports. "Rather, the higher temperatures and more intense UV...

Global heating has made the ocean around the equator less rich in wildlife, with conditions likely already too hot for some species to survive, according to a new study. Analysis of the changing locations of almost 50,000 marine species between 1955 and 2015 found a predicted impact of global heating—species moving away from the equator—can now be observed at a global scale. The study said further global heating, which is now unavoidable, would cut the richness of species in the ocean in tropical regions even further. Scientists said the consequences of the shift could be profound and would be challenging to predict. Species attached to the ocean floor had not declined, but the diversity of free-swimming species such as fish had dropped significantly between 1965 and 2010, said...
    HAVANA – During some summers, as the Caribbean water temperatures climb, the luminous coral colonies of gold, green and blue that ring the island nation of Cuba give way to patches of skeletal white. The technicolor streaks of darting tropical fish flash less frequently. The rasping sounds of lobsters go quiet. While Cuba’s marine life has suffered from overfishing and pollution, there is mounting evidence that the warming of waters due to climate change may be taking a large toll as well — both off the island’s coast and globally. Research published Monday finds that the total number of open-water species declined by about half in the 40 years up to 2010 in tropical marine zones worldwide. During that time, sea surface temperatures in the tropics rose nearly 0.2 degree Celsius. “Climate change is already impacting marine species diversity distribution,” with changes being more dramatic in the Northern Hemisphere where waters have warmed faster, said study co-author Chhaya Chaudhary, a biogeographer at Goethe University. While numerous factors like overfishing have impacted tropical species, the study published in the Proceedings...
    Earth isn’t the only planet that experiences a changing of the seasons. The Hubble Space Telescope has revealed the colorful transition from summer to fall in Saturn’s northern hemisphere — a change years in the making. Saturn, the sixth planet from the sun and the second largest in our solar system, takes about 29 Earth years to complete one orbit around our star. That means that each season on the ringed gas giant lasts more than seven Earth years. Astronomers have tracked summertime on Saturn for the last few years, capturing images of the planet’s northern hemisphere in 2018, 2019 and 2020. Along the way, they’ve seen changes within Saturn’s turbulent atmosphere at the polar regions and around the equator. “These small year-to-year changes in Saturn’s color bands are fascinating,” said Amy Simon, planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement. “What we found was a slight change from year-to-year in color, possibly cloud height, and winds — not surprising that the changes aren’t huge, as we’re only looking at a small fraction of...
    MIAMI (CBSMiami) – Spring season begins in the Northern Hemisphere this Saturday on March 20th at 5:37 a.m. This event also marks the Spring Equinox which is also known as the Vernal Equinox or March Equinox. It occurs when the sun crosses over the “celestial equator.” READ MORE: COVID In Florida: State Nears Two Million Cases, 54 Additional Deaths Reported Just imagine yourself floating in deep space and you can see the Earth and the sun at the same time. You first focus on the Earth’s equator. Then you imagine a straight line extending outward from the equator into space and toward the sun. This line is the celestial equator. As your eyes follow the line, going away from Earth, you find the sun on the other end but you notice that the sun is still hanging just south of the line. You then observe the sun positioning itself from south of the line to just north of the line. This is the Spring Equinox occurring right before your very eyes. Except the sun is not actually moving, instead...
    This year's vernal equinox takes place this Saturday morning at 9:37am GMT – officially marking the arrival of spring for the Northern Hemisphere.  The equinox marks the point when the Sun appears to shine directly over the equator and daytime and nighttime are nearly equal lengths. After the vernal equinox, the Northern Hemisphere will start seeing more hours of daylight than darkness each day.  The astronomical event, which has been celebrated for centuries, is seen as heralding new beginnings and the renewal of the natural world.  Stargazers in the Northern Hemisphere will also be able to enjoy views of Mars and several constellations on Saturday night without a telescope.  Scroll down for video  There are two equinoxes every year - in September and March - when the Sun shines directly on the equator and the length of day and night is nearly equal. During equinoxes, we experience pretty average temperatures and equal lengths of day and night RELATED ARTICLES Previous 1 Next Largest asteroid of 2021 that's twice the size of the Eiffel...

    A FASCINATING video has revealed how Earth's tectonic plates have moved the continents around like jigsaw pieces over a billion years. The 40 second clip was put together by scientists and shows how America was once very close to Africa. 2The video shows how the tectonic plates pulled the continents apartCredit: EarthByte / YouTube Tectonic plates cover the Earth like a patchwork quilt. They're essentially giant slabs of rock that form part of the Earth's crust and they're always moving. These movements are normally so minuscule we don't even notice but sometimes friction between two plates can trigger devastating earthquakes. Volcanic activity, tidal patterns and animals and their evolution are all affected by the slow drift of the plates. 2The researchers think Earth looked like this one billion years agoCredit: EarthByte / YouTube Geoscientist Michael Tetley told Euronews: "For the first time a complete model of tectonics has been built, including all the boundaries. "On a human timescale, things move in centimetres per year, but as we can see from the animation, the continents have been everywhere in time. "A place...
    A message in a bottle dropped by an American girl was found nearly two years later after traveling 1,500 miles to Papua New Guinea. Conservation ranger Steven Amos found the message dropped by 17-year-old Niki Nie while he was cleaning the beachfront on Panasesa island. Niki was sailing to the Marshall Islands from Vanuatu with her family when she dropped the bottle while crossing the equator on January 8, 2019. She left her email in the message and the pair struck an unlikely friendship nearly two years later over a chat on Zoom.

    A dark storm 4,600 miles across on the distant ice giant Neptune has left astronomers confused after it changed direction, a phenomenon never seen before. Storm vortices like Neptune's dark spot aren't unusual, but nobody had previously witnessed one turning back towards the poles after migrating to the equator.   Using images from the Hubble space telescope, University of California, Berkeley astronomers said the change of direction was 'unexpected' and surprising. The storm is wider than the Atlantic Ocean on Earth and was first discovered by Hubble in 2018 where it was born in the northern hemisphere of Neptune. A year after it was first observed it had started migrating towards the equator, but the latest observations from August 2020 show it moving back to the north. Hubble has tracked similar dark spots over the past 30 years but this 'unpredictable atmospheric behaviour' is something never before witnessed by astronomers.  Storm vortices like Neptune's dark spot aren't unusual, but nobody had previously witnessed one turning back towards the poles after migrating to the equator This massive storm wasn't alone,...
    A revolution in understanding the evolution of seals It was previously thought that all true seals originated in the North Atlantic, with some later crossing the equator to live as far south as Antarctica. The Eomonachus specimen now shows that many ancient seals, including the ancestors of today’s monk, elephant, and Antarctic seals, they actually evolved in the southern hemisphere. According to paleontologist James Rule, who led the research: “This new species of extinct monk seal is the first of its kind in the southern hemisphere. Its discovery really revolutionizes the evolution of seals.” “Until now, we think that all true seals originated in the Northern Hemisphere and then crossed the equator only once or twice during their entire evolutionary history. Instead, many of them appear to have evolved in the South Pacific and then crossed the equator. up to eight times, “he continues. For Dr. Felix Marx of the Te Papa Museum in New Zealand, this discovery represents a triumph for citizen science: “This new species has been discovered thanks...
    High in the skies during a recent nighttime flight near the equator, a military aircrew captured a rare weather phenomenon outside their window. The Royal Air Force’s 99 Squadron released a video on Monday showing the phenomenon known as a "St. Elmo’s Fire." The fork-shaped discharge of atmospheric electricity is not lightning but has a similar look. RARE WEATHER PHENOMENON 'ST. ELMO'S FIRE' CAPTURED BY HURRICANE HUNTER AIRCRAFT IN NORTH ATLANTIC The RAF said the C-17 crew experienced it while flying through the Inter Tropical Convergence Zone (ITCZ) at night. Video released by the RAF on Twitter shows the flashes of light as the aircraft flies in darkness. "The electrical weather phenomenon of St Elmo’s Fire isn’t dangerous, but it usually means you’re surrounded by storms!" the RAF tweeted. The ITCZ is the region that circles the Earth, near the equator, where the trade winds of the Northern and Southern Hemispheres come together. HUGE BIRD MIGRATION SPOTTED ON WEATHER RADAR According to Encyclopedia Britannica, the phenomenon, also known as a corona discharge, is “commonly observed on the periphery of propellers and along the wingtips, windshield and nose of aircraft flying...
    Scientists spotted a mysterious giant cloud hanging over the surface of Mars in 2018 and it has recently reappeared on the Red Planet. Made of water ice, the elongated cloud sits 12.4 miles above the volcano Arsia Mons and stretches some 1,110 miles in length.  Scientists have coined the formation the 'Arsia Mons Elongated Cloud (AMEC) and noticed it seems to appear around Mars's southern summer solstice – when the southern hemisphere is hit with a large amount of daylight. However, experts are not clear why it has formed, how long it will stay or when it will disappear from the Martian atmosphere.  The cloud was spotted in images of Mars taken July 17 and 19 by the Visual Monitoring Camera (VMC) onboard the European Space Agency's (ESA) Mars Express The cloud was spotted in images of Mars taken July 17 and 19 by the Visual Monitoring Camera (VMC) onboard the European Space Agency's (ESA) Mars Express.

    Madrid / Logroño, Jul 10 (EFE) .- The kings will support the wine sector on Friday during the visit they will make to La Rioja, the community with which they arrive at the equator of the regional tour they are conducting after the state of alarm that decreed to deal with the coronavirus pandemic. In their eighth trip on this tour, Felipe VI and Doña Letizia will star in an agenda that will take them to the municipalities of Haro and Santo Domingo de la Calzada. Last March, Haro was one of the first towns in Spain to concentrate a high number of coronavirus positives, since a family had attended a funeral in Vitoria where its members were infected. Later, Santo Domingo de la Calzada was another of the points of La Rioja most affected by COVID-19. The kings will express their support for the institutions and groups after the work they have had to do to face the consequences of the pandemic and, in an eminently wine-growing community, they will have a special gesture of support for this sector...
