Scientists have a lot to learn about living animals before presuming to speak of long-lost extinct ones.Tree croc: Scientists have confirmed anecdotal reports that some crocodiles and alligators can climb trees. “When most people envision crocodiles and alligators, they think of them waddling on the ground or wading in water — not climbing trees,” Science Daily reported. “However, a new study has found that the reptiles can climb trees as far as the crowns.” Scientists from U of Tennessee found 4 species on 3 continents (Australia, Africa and North America) engaging in tree climbing. They think the reptiles do it to regulate their body temperature by basking, or to improve their view for surveillance. Small ones could venture farther than big ones, but “the ability to climb vertically is a measure of crocodiles’ spectacular agility on land.”Alpine bumblebee: Science Magazine reported that bumblebees appear capable of flying higher than Mt. Everest. “The last thing you’d expect to see out your airplane window is a bumblebee cruising by,” the article says. “But a new study suggests that the insects might be capable of such high-altitude jaunts.” Chinese researchers studied some bees found at high altitude, and experimented with their limits, finding some capable of thriving 100 meters above the elevation of Everest. The bees appear to compensate for the lower air pressure by flapping at the same speed but with greater amplitude.High wings: Quick: What bird flies the highest altitude? According to the BBC News, its Reppell’s vulture, found at 37,000 feet (presumably with bumblebee companions). The article gives “Seven surprising facts about vultures,” including their big appetites, ability to fly high and for long distances, and their varied diet and strong stomachs for digesting carrion. “Bearded vultures are the only animals known to have a diet of 70-90% bone and their stomach acid allows them to take nutrients from what other species discard,” the article says, noting that the stomach acid can neutralize cholera, anthrax and even botulism toxin – the strongest poison in the world (one gram could kill a billion humans). Thanks in part to vultures, the world is cleansed of decaying dead animals. One vulture carrying two dead rats was blocked at the airport gate recently. The reason? He was only allowed one carrion.Flying snakes: A video clip on the BBC News, and an accompanying article, show that some snakes in Southeast Asia can shape themselves a bit like an S-shaped Frisbee and glide through the air for long distances after flinging itself off tree branches. “Scientists say that the serpents radically alter their body shape to generate the aerodynamic forces needed to perform this feat.” A photo caption reads, “The aerodynamic forces are comparable with those generated by a plane’s wing.”Weightlifter ants: Ants are capable of sustaining “astounding pressures” on their necks, Science Daily said, calling their necks “amazing” and worth studying for improving robot strength. These aren’t specially trained ants, either, but just common American field ants. Measurements with centrifuges show the neck can withstand 5,000 times the ant’s body weight, due to a combination of materials and the structure of the joints. These leave the muscles free to lift and position objects.Sneezing sponges: This headline on Science Daily says it all: “Sneezing sponges suggest existence of sensory organ: Discovery challenges assumptions about ‘primitive’ organism.” How can an animal without a nervous system have a sense organ? That was the question a young biologist, Danielle Ludeman, decided to ask at the University of Alberta. “The sponge is a filter feeder that relies totally on water flow through its body for food, oxygen and waste removal,” the article explained. “Sneezing, a 30- to 45-minute process that sees the entire body of the sponge expand and contract, allows it to respond to physical stimuli such as sediment in the water.” This seems to presuppose sensory ability, but where did it reside? Ludeman and her supervisor, Sallie Leys, found ciliated cells lining the osculum. As evolutionists, they are trying to figure out whether this evolved uniquely in the sponge or is common to all animals. For a sponge, one of the simplest multicellular animals of all, to have a sense organ is “totally new,” not found in textbooks; “this doesn’t appear in someone’s concept of what sponges are permitted to have,” Leys said.Controlled power dive: Peregrine falcons can dive at 200 miles an hour, an article on Science Daily says. Experiments with specially designed wind tunnels shows that their feathers appear to act as “self-adaptive flaps” during dives. The body also changes shape during descent.Monarch crisis: Long live the king! We end with a sad story of the precipitous decline of Monarch butterflies, reported by Live Science and Science Now. These long-distance travelers, highlighted in the Illustra film Metamorphosis: The Beauty and Design of Butterflies, are in trouble – this time, it appears truly because of human interference. It’s not just their home in the mountains of Mexico that is threatened by logging. Use of pesticide-resistant crops in the USA has allowed many farmers to spray their fields with Roundup, killing off the milkweed on which the butterflies depend. Drought in Texas may also be a factor. Once a billion butterflies met in Mexico; now, 33.5 million were estimated during a 9-year decline. Unless quick measures are taken to restore the milkweed, this long-distance migration, a wonder of nature, is at risk of being lost.No matter where you look, the living world is filled with astonishing design. How can anyone attribute these feats to blind, aimless forces? Evolution amounts to a cop-out explanation, like saying, “Well, if they weren’t that way, they would have gone extinct” or “Stuff happens.” Come now, and let us reason together. Mistakes, in our day-to-day experience, do not generally cause exquisite design. Good design is a product of engineering. Why not make the logical inference? These animals don’t just show passable design. They show elegant, exquisite, astonishing design, as if Someone with omniscience, omnipotence, and wisdom had a plan. Follow the evidence.

Sachin Tendulkar is set to another feather to his already crowded cap as Australian Prime Minister Julia Gillard on Tuesday announced that the iconic Indian cricketer will be conferred the membership of the Order of Australia, an honour “rarely” awarded to non-Australians.The 39-year-old Tendulkar, who is currently in South Africa playing in the Champions League Twenty20, will become only the second Indian after former Attorney General Soli Sorabjee to get the honour.Sorabjee was made an Honorary Member of the Order of Australia (AM) “for service to Australia-India bilateral legal relations” in 2006.”Cricket is of course a great bond between Australia and India. We are both cricket-mad nations. I am very pleased that we are going to confer on Sachin Tendulkar, membership of the order of Australia (AM),” Gillard, who is on a visit to India, told reporters here.”This is a very special honour very rarely awarded to someone who is not an Australian citizen or an Australian national. The award will be conferred on him by cabinet Minister Simon Crean when he visits India,” she said.”So, a special honour and a very special recognition of such a great batsman. The honour is very special and Sachin is a very special cricketer.”Tendulkar is not the first cricketer to be made an Order of Australia AM as in 2009, West Indies legend Brian Lara was also made an honorary member.Another West Indies legend, Clive Lloyd, is an Honorary Officer in the Order of Australia, having been conferred the award way back in 1985.advertisementThe right-handed Tendulkar, considered the finest batsman in contemporary cricket, has 15,533 runs in 190 Tests besides a mammoth 18,426 runs in 463 ODIs.

Andrew Hoyle/Roadshow Subaru has yet another installment in its range of Viziv concept cars, this time called the Adrenaline — and not to be confused with Ford’s Adrenalin treatment. But rather than previewing a totally new model — even if it does look like a dead ringer for a next-generation Crosstrek — Subaru says the Adrenaline instead shows the company’s new design language, dubbed “Bolder.””Through the new ‘Bolder’ design philosophy, Subaru aims to broaden the brand’s outlook, define the characteristics of Subaru vehicles more prominently and create more enjoyment for all passengers,” the company said in a statement at the Geneva Motor Show.It’s definitely a Subaru alright — definitely not what we’d call pretty, but purposeful and kind of rugged-cute. The gray cladding on the front fender seems to follow the headlight design in a weird way, but we dig the rounded-off rump. Subaru says the Adrenaline’s roof design actually uses parts that reinforce the body structure, and that overall, the styling is meant to “express the toughness and agility” of this concept car.Because this is a design-focused concept, Subaru doesn’t have any information about what kind of powertrain might be under the hood, and it’s not apparent that the car has an interior, either. Still, look for design elements from this concept to show up on future Subarus.

Explore further The biggest advantage of ultracapacitors is that they can fully recharge in less than a minute, unlike lithium-ion batteries which can take several hours. The downside of ultracapacitors is that they currently have a very short range, providing a distance of only a few miles, due to the fact that ultracapacitors can store only about 5% of the energy that lithium-ion batteries can hold. Although their short range makes ultracapacitors impractical for cars, city buses have to stop frequently anyway. By quickly recharging at bus stops, buses could take advantage of ultracapacitors’ other benefits: a bus with ultracapacitors uses 40% less electricity compared to an electric bus with lithium-ion batteries, and requires just one-tenth the energy cost of a typical diesel-fueled bus, which would save about $200,000 during the life of the vehicle. Plus, the buses are environmentally friendly: “Even if you use the dirtiest coal plant on the planet, it generates a third of the carbon dioxide of diesel when used to charge an ultracapacitor,” said Dan Ye of Sinautec.Today’s demonstration will take place at American University in Washington, DC, where an 11-seat minibus powered by ultracapacitors will be shuttling people around campus. At designated charging stations, which double as bus stops, the bus recharges by raising a collector on top of the bus a few feet to touch an overhead electric charging line, which recharges ultracapacitor banks stored under the bus seats. The two companies hope that this is just the beginning for ultracapacitor buses. The company that makes the Shanghai buses, Foton America Bus Co, based in Tennessee, plans to deliver another 60 buses to the Chinese city in early 2010. The new buses will have ultracapacitors manufactured by Shanghai Aowei that supply 10-watt hours per kilogram, compared with the current ultracapacitors that have an energy density of six watt-hours per kilogram. Other US cities, including New York City, Chicago, and some towns in Florida, have also expressed interest in trialing the buses. The companies expect that the ultracapacitors will continue to achieve higher energy densities in the future, which would allow them to hold a charge for longer. This improvement could increase the driving range from a few miles to 20 miles or more, helping to decrease the number of charging stations required on a route and make the technology practical for many more cities and bus routes. More information: Sinautecvia: Technology Review© 2009 PhysOrg.com (PhysOrg.com) — A fleet of 17 buses near Shanghai has been running on ultracapacitors for the past three years, and today that technology is coming to the Washington, DC, for a one-day demonstration. Chinese company Shanghai Aowei Technology Development Company, along with its US partner Sinautec Automobile Technologies, predict that this approach will provide an inexpensive and energy efficient way to power city buses in the near future.
