first_imgDating of artifacts and fossils may become much more common thanks to a new instrument.Without doubt, radiocarbon dating has been an exciting and contentious process. It has been able to resolve disputes about the construction date of archaeological sites, such as Hezekiah’s Tunnel in Jerusalem (9/10/03). Creationists find radiocarbon all over in places it shouldn’t be (see Real Science Radio’s list), such as coal and diamonds; evolutionists cry “contamination!” (Note: all radiocarbon should vanish from a sample before 100,000 years). Resolving disputes has been costly and time-consuming. Typically, the best results come from labs with equipment for accelerator mass spectroscopy (AMS), but only 100 or so labs worldwide have the equipment.What would happen if you could get radiocarbon dates almost as accurate as AMS at one tenth the cost, within two hours? This may become common, if the encouraging announcement from Italy’s Istituto Nazionale di Ottica lives up to its promises. Science Daily says,The instrument, which uses a new approach called saturated-absorption cavity ring-down (SCAR), is described in The Optical Society’s journal for high impact research, Optica. SCAR offers significant time and cost savings compared to the standard approach for carbon dating and could be useful for a host of other applications such as measuring emissions from fossil fuels or certifying the amount of biogenic content in biofuels.The equipment, which works on a laser cavity principle, is smaller, faster, and cheaper. It costs a tenth of AMS. It might even become portable. Each test, furthermore, is half the cost of AMS, the article says:The researchers report that their SCAR instrument can detect radiocarbon dioxide concentration with a precision of 0.4 percent, which approaches the 0.2 percent precision of the best accelerator mass spectrometers. The new technique can deliver results in just two hours, with each test costing about half what it would if conducted using an accelerator mass spectrometer.The researchers estimate the SCAR instrument is about 100 times smaller and 10 times cheaper than the instrumentation required for accelerator mass spectrometry. Its size and cost could decrease even more once the instrument is converted from its current tabletop version to a more portable commercial prototype.The designers envision archaeologists being able to test artifacts in the field. “This could revolutionize the approach that archaeologists use for carbon dating because they would not have to send sensitive samples away to a lab and wait weeks for a result,” one of the team members said.We hope radiocarbon dates will become much easier to obtain, so that creation researchers can test samples of coal, diamond and dinosaur bone quickly and cheaply. This technique, if it fulfills the promises, could make possible multiple tests on the same sample by different labs or teams, reducing the credibility of charges about contamination. Many more samples could be dated. There should be zero radiocarbon in samples older than 100,000 years. Enough undisputed radiocarbon-positive results on “old” samples could completely undermine the evolutionary timeline. Let’s get the data!

first_imgKolkata will be eager to maintain their 13-game winning streak as they take on Dolphins todayWelcome to the coverage of Match 18 in the Champions League Twenty20 between Kolkata Knight Riders and Sunfoil Dolphins from the Rajiv Gandhi International Cricket stadium in Hyderabad.ScorecardSunfoil Dolphins managed to score 151 runs while chasing an imposing total of 187 runs against Kolkata Knight Riders at Uppal. It is a comprehensive win for Kolkata and Gambhir’s men extend their unbeaten streak to 13 matches, which is the most by an Indian team. Yusuf and Russell struck early and had Dolphins at 6/2. van Wyk and van Jaarsveld rebuilt the innings, but fell in quick succession. Zondo and Phehlukwayo hit some meaty blows and kept them in the hunt, but once they perished it was just a matter of time for Kolkata to complete the formalities. Gambhir tried out a few different options, like opening the bowling with Yusuf, giving Suryakumar and Tendo a bowl. At the end, it was Narine who did most of the damage with his 3 wickets, he was well supported by the rest of the bowlers. Dolphins showed glimpses of what they are capable of, but return home without a win.Most consecutive wins in T20s!Top 3 Teams :- 25 Sialkot- 14 Otago- 13 #KKRCongrats Everyone @iamsrk @KKRiders !!

Gautam Gambhir and Robin Uthappa are out in the middle for Kolkata while Kyle Abbott will start the proceedings for Dolphins. Toss: Kolkata Knight Riders won the toss and elected to bat first against Sunfoil Dolphins. Kolkata, who have been riding on the wings of winning 13 matches in a row will take on the whipping boys of CLT20 2014, Dolphins. It is an inconsequential match in the sense that Kolkata have won all their three matches till now. At the other end of the spectrum, despite showing flashes of brilliance, Dolphins have lost all their games so far.Quotes:”I think the guys have taken up great responsibility. Unbelievable knock from Suryakumar Yadav(against Perth) and it’s the best knock I’ve seen from such a young guy. He’s got a great head on his shoulder and he’s got a great future. To see Kuldeep bowl well is very pleasing. We need someone who can compliment Sunil and Kuldeep is a perfect fit. Yusuf bowled well and it could help him in his batting as well. There is a lot of hunger in the dressing room and that is the secret about doing well,” Gautam Gambhir said.”It looked closer than it was really, but credit to Robbie for it. It would have been nice if there was a batsman to help him. We will learn from this experience. The batting was an issue, the bowling was OK, although we should have chased some 20 runs less. We want to show we can play good cricket, will look to do well against Kolkata. We can do much better, we will try and show the Dolphins brand of cricket. It has been a wonderful experience playing cricket in India, it is a wonderful country. It has been a good exposure for our guys, we can go back, work on our batting and do better in the future,” Morne van Wyk said after Dolphins lost a cliffhanger to Lahore Lions.Kolkata Knight Riders:Kolkata have shown the required resilience and self-belief to make their mark in the tournament. The likes of Ryan Ten Doeschate, Andre Russell, Gautam Gambhir and Suryakumar Yadav have chipped in with useful runs as and when required under pressure-cooker situations.It shows that they don’t just depend on one or two players in the batting line-up to make their mark.However, it has been their bowlers, who have played a pivotal role in helping them to win games. They have wicket-taking spinners like Sunil Narine and Kuldeep Yadav to make those crucial breakthroughs. Narine has always been a threat with his box of tricks.However, the emergence of Yadav, with his left-arm chinaman bowling has added more firepower to their line-up. Till now most of the batsmen have failed to pick Yadav’s variations.Sunfoil Dolphins:Kolkata’s opponents, Dolphins, have played with boyish enthusiasm in CLT20. However, they don’t have the results to show for it. It is up to them to put up a fine performance in their last game of the tournament and at least go back to South Africa with a win under their belt.Among their bowlers, Kyle Abbott has bowled well in patches. The seamer can trouble the batsmen with the new ball, as he hits good lines and lengths and sticks to his plans. Robbie Frylinck, who impressed one-and-all in their last game against Lahore Lions can vary his pace and when needed, bowl yorkers.In the batting department, Khaya Zondo, Morne van Wyk, the captain and Cameron Delport have caught the eye, but haven’t been consistent enough. It was Frylinck yet again whose power-hitting against Lahore sent the crowd into a tizzy. Their ground fielding has been of acceptable standards.Teams(from):Kolkata Knight Riders: Gautam Gambhir(c), Robin Uthappa(wk), Manish Pandey, Yusuf Pathan, Ryan ten Doeschate, Suryakumar Yadav, Andre Russell, Piyush Chawla, Sunil Narine, Vinay Kumar, Umesh Yadav, Kuldeep Yadav, Jacques Kallis, Pat Cummins, Manvinder BislaSunfoil Dolphins: Morne van Wyk(c/wk), Cameron Delport, Cody Chetty, Keshav Maharaj, Jonathan Vandiar, Khayelihle Zondo, Vaughn van Jaarsveld, Robert Frylinck, Andile Phehlukwayo, Kyle Abbott, Prenelan Subrayen, Daryn Smit, Daryn Miles Dupavillon, Craig Alexander, Sibonelo Makhanyalast_img read more
