The Venus flytrap’s habit of chowing down on flies and other bugs may be centered around its ability to count — as in how many times it needs to be touched before clamping down on its prey, according to a new study.
While the carnivorous plant does not apply Common Core math solutions to know when it’s meal time, the Venus flytrap has the ability to keep track of the number of times it is touched, allowing it to react on a routine basis to bugs.
In the Cornell paper they address the cosmic frequency of technological species. Recent advances in exoplanet studies provide strong constraints on all astrophysical terms in the Drake Equation. Using these and modifying the form and intent of the Drake equation they show that we can set a firm lower bound on the probability that one or more additional technological species have evolved anywhere and at any time in the history of the observable Universe.
The researchers find that as long as the probability that a habitable zone planet develops a technological species is larger than ~10?24, then humanity is not the only time technological intelligence has evolved. This constraint has important scientific and philosophical consequences.
Scientists have successfully spliced Woolly Mammoth DNA into the DNA of an Asian Elephant. The scientists spliced genes for the mammoths’ small ears, subcutaneous fat, and hair length and color into the DNA of elephant skin cells.
But don’t expect baby Mammoth clones any time soon.
To stay warm when temperatures drop outside, we heat our indoor spaces — even when no one is in them. But scientists have now developed a novel nanowire coating for clothes that can both generate heat and trap the heat from our bodies better than regular clothes. They report on their technology, which could help us reduce our reliance on conventional energy sources, in the ACS journal Nano Letters.
At the heart of this new clock is the element strontium. Inside a small chamber, the strontium atoms are suspended in a lattice of crisscrossing laser beams. Researchers then give them a little ping, like ringing a bell. The strontium vibrates at an incredibly fast frequency. It’s a natural atomic metronome ticking out teeny, teeny fractions of a second.
NASA is looking for ways to reduce the cost of sending humans to Mars. Their study explores dramatically cutting the cost of a human expedition to Mars by putting the astronauts into a deep sleep called “torpor” that would use existing medical procedures to reduce astronauts’ metabolic functions. Torpor can also occur naturally in cases of hypothermia.
Blended with intravenous feeding, a crew could be in a state of hibernation for the transit to Mars, which at best would be 180 days each-way.
This is a good article on EETimes about the emotional attachment that can happen in the family between their robotic pet and the risks we face as those mechanical loved-ones age over time. Also covers pitfalls in our lives when a machine becomes human.
In a short Q&A interview with Forbes Magazine, Chinese-American astronaut Leroy Chiao advocates embracing China, rather than shunning it, in the new space race to Mars . He also talks about the recent spying charges USA and China are batting back and forth and what that should mean wrt better cooperation in space.
Leroy also touches on the current Russia/USA relations and gives a little insight into the impact it’s having on the shared space exploration efforts onboard the International Space Station.
I totally agree with Leroy on the China+USA collaboration to get to Mars. We’re both highly motivated countries regarding space exploration. China in particular may be willing to foot more of the $$$/RMB cost if there’s more sharing of technology between us. I think we stand a better chance of pulling off this huge effort working together, rather than in isolation.
As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water that is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell – huge waves that could add a new and unpredictable element to the region.
A University of Washington researcher made the first study of waves in the middle of the Arctic Ocean, and detected house-sized waves during a September 2012 storm. The results were recently published in Geophysical Research Letters.
“As the Arctic is melting, it’s a pretty simple prediction that the additional open water should make waves,” said lead author Jim Thomson, an oceanographer with the UW Applied Physics Laboratory.
The literature in question? The novels of Jane Austen. Chwe discovered that Austen’s novels are full of strategic thinking, decision analysis, and other tools that would later come to be prized by game theorists like those as the RAND Corporation just after World War II.
Molars taken from skeletons unearthed by work on a new London railway line are revealing secrets of the medieval Black Death — and of its victims.
This week, Don Walker, an osteologist with the Museum of London, outlined the biography of one man whose ancient bones were found by construction workers under London’s Charterhouse Square: He was breast-fed as a baby, moved to London from another part of England, had bad tooth decay in childhood, grew up to work as a laborer, and died in early adulthood from the bubonic plague that ravaged Europe in the 14th century.
This snap shows the Majestic Sombrero Galaxy, it’s my favorite galaxy out of the hundreds of billions out there. A brilliant white core is encircled by thick dust lanes in this spiral galaxy, seen edge-on in this view. The galaxy is 50,000 light-years across and 28 million light years from Earth.
Shanghai’s Fudan University scientists have created an affordable and efficient one-watt light bulb that produces its own Wi-Fi signal. Scientists found that the prototype that uses a technology called Li-Fi, works faster than the average connection in China. The Li-Fi bulb featuring a microchip generates around 150 mbps, 20 times faster than average broadband connection in China.
