Business Kroes launches European start-up accelerator 2014/01/27 EC vp Neelie Kroes launched a new start-up accelerator at Davos. Called the Startup Europe Partnership, the founding organisations are: Telefonica, Orange, BBVA, European Investment Bank, Cambridge University, IE Business School, Humboldt University, the Lisbon Council, Nesta and Mind the Bridge Foundation. “Europe needs thriving startups and global internet companies to become a global growth centre again,” Kroes said. The Startup Europe Partnership will help start-ups break through their national glass ceiling into global maturity. Its secretariat will be led by the Mind the Bridge Foundation, a non-profit corporation and Nesta, the UK’s innovation foundation. “Politicians don’t create jobs, entrepreneurs do,” said Kroes, “we’re going to support that mindset and push European start-ups beyond their comfort zone. And then we’re going to get out of the way. Sometimes the best thing a political leader can do is ge...

石中之王田黄石鉴藏 　　所谓田黄，即寿山石中的特殊品种，因产于福建寿山村坑头溪两岸水田及河流底部的沙砾层中而得名。其质地细腻、温润，手摸有滑感，并常有石皮、红格、罗卜纹等标志。田黄作为我国特有的“软宝石”之一，在全世界范围内只有我国福建寿山一块不到1平方公里的田中出产，因此产量极其有限。需要注意的是，并非任何田黄都具有很高的收藏价值。田黄的质地优劣悬殊，价值高低差异极大，不能一概而论。多数用于收藏与投资的田黄也仅是其中少部分特征明显、各方面俱佳而无可挑剔的上品。因此，如何品鉴上品田黄石材或田黄印章就成为田黄初学者必须掌握的要领。 　　1.石形。田黄的母石为山料，呈棱角状，经过重力与水流的搬运及磨蚀作用，其棱角逐渐圆化，形成形态多样、大小不一的卵石(独石)，呈次棱角状或次圆状。如果发现棱角尖锐或浑圆光滑的“田黄”就值得怀疑，可能为掘性石或山料磨制而成，但如果在加工过程中破坏了其原形就难以识别了。田黄一般为几十克至几百克，超过千克的非常罕见，几公斤的田黄应值得警惕。 　　2.石皮。田黄长期埋藏在水田中，经风化作用，其外表通常会形成不同特征的皮层。田黄的皮色主要有黄色、黑色与白色。黑色皮俗称“乌鸦皮”；皮为白色而石色为黄色，称为“银包金”；皮为黄色而石色为白色，称为“金包银”。田黄的不同皮色可能与不同颜色的土质有关，即黄色的土壤形成黄色皮，黑色的土壤形成黑色皮。由于田黄普遍发育石皮，有“无皮不成田”之说，故石皮成为鉴定田黄的重要特征之一。 　　3.萝卜丝纹。采用透射光观察田黄的内部，其普遍发育似“萝卜丝纹”纹理，是非常重要的鉴定特征。田黄内部的“萝卜丝纹”多种多样，发育程度不同，按粗细可分为条带状、条纹状与细丝状；按形态可分为直线形、网状形与不规则形；按颜色可分为白色、黄色与棕色；按透明度可分为半透明与微透明。田黄基本上都具有“萝卜丝纹”，“无纹不成田”的说法成立，但不能绝对化。 　　4.红格(或红筋)。田黄的“格”或“筋”实际上是一种裂隙，这些裂隙在地表条件下，特别是水田里，普遍受到Fe2O3溶液的渗入与沉淀，被染成黄红色，故称为红格或红筋。但也有少数没有颜色，为白色裂隙，则称为无色格。田黄有红格(或红筋)的现象较普遍，也有“无格不成田”之说。文/梦想风云 TAG: 石中之王田黄石鉴藏

Psychologists document the age our earliest memories fade Jan. 24, 2014 — Although infants use their memories to learn new information, few adults can remember events in their lives that happened prior to the age of three. Psychologists at Emory University have now documented that age seven is when these earliest memories tend to fade into oblivion, a phenomenon known as "childhood amnesia." Share This: The journal Memory published the research, which involved interviewing children about past events in their lives, starting at age three. Different subsets of the group of children were then tested for recall of these events at ages five, six, seven, eight and nine. "Our study is the first empirical demonstration of the onset of childhood amnesia," says Emory psychologist Patricia Bauer, who led the study. "We actually recorded the memories of children, and then we followed them into the future to track when they forgot th...

Interplanetary dust particles could deliver water and organics to jump-start life on Earth Interplanetary dust, dust that has come from comets, asteroids, and leftover debris from the birth of the solar system, continually rains down on Earth and other Solar System bodies. These particles are bombarded by solar wind, predominately hydrogen ions. This ion bombardment knocks the atoms out of order in the silicate mineral crystal and leaves behind oxygen that is more available to react with hydrogen, for example, to create water molecules. "It is a thrilling possibility that this influx of dust has acted as a continuous rainfall of little reaction vessels containing both the water and organics needed for the eventual origin of life on Earth and possibly Mars," said Hope Ishii, new Associate Researcher in the Hawaii Institute of Geophysics and Planetology (HIGP) at UHM SOEST and co-author of the study. This mechanism of delivering both water and organics simultaneously would also...

Rainforests in Far East shaped by humans for the last 11,000 years The rain forests of Borneo, Sumatra, Java, Thailand and Vietnam were previously thought to have been largely unaffected by humans, but the latest research from Queen's Palaeoecologist Dr Chris Hunt suggests otherwise. A major analysis of vegetation histories across the three islands and the SE Asian mainland has revealed a pattern of repeated disturbance of vegetation since the end of the last ice age approximately 11,000 years ago. The research, which was funded by the Arts and Humanities Research Council and the British Academy, is being published in the Journal of Archaeological Science. It is the culmination of almost 15 years of field work by Dr Hunt, involving the collection of pollen samples across the region, and a major review of existing palaeoecology research, which was completed in partnership with Dr Ryan Rabett from Cambridge University. Evidence of human activity in rainforests is extremely difficult...

40 percent of parents learn how to use technology from their children Jan. 24, 2014 — Just how are adults learning to use technology? Chances are if you are a parent, your child is teaching you. A recent paper published in the Journal of Communication found that between 30%-40% of parents were taught how to use the computer and Internet from their children. Share This: Teresa Correa, University Diego Portales (in Santiago, Chile), conducted in-depth interviews with 14 parent/child sets and surveyed 242 parent/child sets. She found that youth influence their parents in all technologies studied (computer, mobile Internet, social networking) up to 40% of the time. The children's scores were higher compared to parents, showing that parents don't necessarily recognize the influence. Parent's also learned how to use technologies by self-experimentation. This bottom-up influence process was more likely to occur with mothers and lower socio...

Mars could have supported life: Ten years on Mars leads to livable mud The findings were announced in a special 'Exploring Mars Habitability' edition of the journal Science released today to coincide with the 10th anniversary of the Mars Opportunity Rover and its twin, Spirit, landing on the red planet. CSIRO's Dr Paulo de Souza, who is on the science team led by Cornell University's Professor Steven Squyres, said a major focus on NASA's decade of research on Mars surface was whether the planet may ever have been habitable. "While Mars is too cold now to have the liquid water needed for life, we've had evidence for past water activity on the planet from satellite images of valleys and analysis of rocks by the Rovers," Dr de Souza said. "If there was ever life on Mars, then this would have been the mud for it to live in." "But the water that once shaped those landscapes and minerals was as acidic as vinegar. "Our latest research has...

Power Electric vehicle wireless charging gets on the road 2014/01/24 I’m on a bus headed for Bletchley Park, but not to visit the UK’s second-world-war codebreaking centre, I’m just along for the ride. That’s because I’m on an electric bus that is one of the first vehicles to use a revolutionary inductive charging technology. Its batteries charge wirelessly when the bus stops to pick up passengers. With no need to plug in to charge, it’s a breakthrough that should speed up the widespread adoption of electric vehicles (EV). Take the Electronics Weekly Salary Survey 2014 » Charging an EV is a laborious process. The owner has to find a charging point, connect up their cable and leave the car for some hours. It’s inconvenient, and cables can easily get lost or damaged. Wireless power transfer technology was developed decades ago, but low efficiency meant it was restricted to industrial settings, providing power for robotic vehicles and cranes, for example. That is finally changing...

3-D Graphene: Super-capacitors from sugar bubbles Jan. 24, 2014 — Graphene sheets are immensely strong, lightweight and excellent at conducting electricity. Theoretically, macroscopical three-dimensional graphene assemblies should retain the properties of nanoscale graphene flakes. However, recent attempts to make 3D graphene have resulted in weak conductivity due to poor contact between graphene sheets. Loss of strength is also a problem, and self-supporting 3D graphene has not yet been produced. Share This: Now, Xuebin Wang and Yoshio Bando at Japan's World Premier International Center for Materials Nanoarchitectonics (WPI-MANA), together with co-workers across Japan and China, have created a new way of making 3D graphene using bubbles blown in a polymeric glucose solution. The resulting 3D graphene is robust and maintains excellent conductivity. Inspired by the ancient food art of 'blown sugar', Bando and his team reasoned that th...

LED Lighting Mid-power infra-red LED in mini-scale package 2014/01/24 Osram Oslon Compact infra-red Surveillance and machine vision are targets for a compact 500mA infra-red LED from Osram. In a 1.6×1.2×0.8mm package, the Oslon Compact SFH 4710 has a typical output of 270mW at hardly-visible 850nm wavelength. Inside is a 0.75×0.75mm chip. “It is a welcome addition to the product portfolio of Osram Opto Semiconductors, occupying the output range between Power TopLED and Oslon Black,” said the firm, adding that it is half the footprint of Oslon Black. Emission angle is +/-65°. “Without external optics the IRED covers the near-field range of a few meters and is therefore suitable for eye tracking and gesture detection,” said Osram. “With external optics it is ideal for illumination in surveillance applications and for machine vision pattern recognition and 3D measurement because the wavelength is barely perceptible to the human eye but can be easily detected by camera systems.” O...
