Centuries-old frozen plants revived
Glacier retreat has markedly accelerated in the period since 2004 - and many new species lie beneath Plants that were frozen during the "Little Ice Age" centuries ago have been observed sprouting new growth, scientists say. Samples of 400-year-old plants known as bryophytes have flourished under laboratory conditions. Researchers say this back-from-the-dead trick has implications for how ecosystem
Higgs Data Suggest Universe Has Finite Lifespan
BOSTON (Reuters) - Scientists are still sorting out the details of last year's discovery of the Higgs boson particle, but add up the numbers and it's not looking good for the future of the universe, scientists said Monday. "If you use all the physics that we know now and you do what you think is a straightforward calculation, it's bad news," Joseph Lykken, a theoretical physicist with the Fermi Na
Scientists discover new monkey species in Congo
A team of scientists has identified a new species of monkey in central Africa that had been known to the locals simply as lesula, a medium-sized, slender animal that looks similar to an owl-faced monkey that was already known to scientists. In findings published this week in the scientific journal Plos One, the researchers identified the species as Cercopithecus lomamiensis, which is endemic to th
Higgs excitement at fever pitch
Professor Jim Al-Khalili explains what the Higgs boson is and why its discovery is so important Scientists at the Large Hadron Collider (LHC) are expected to reveal the strongest evidence yet for the Higgs particle in Geneva shortly. Anticipation is high and rumours have been rife about the announcement. The Higgs boson would help explain why particles have mass, and fills a glaring hole in the cu
Higgs Boson Found? Without "God Particle," No Galaxies—And No Life
Just hours from now, physicists could announce they're 99.9936 percent sure the Higgs boson exists, according to experts on the hunt for the so-called God particle. The combined findings of two teams at the proton-smashing Large Hadron Collider (LHC) should help explain why objects in our universe have mass—and in so doing, why galaxies, planets, and even humans have any right to exist.

太陽活動に異変、地球寒冷期の前兆か？
国立天文台と理化学研究所などの国際チームは19日、太陽極域の磁場にこれまでの活動周期とは違った現象が観測されたと発表した。地球に寒冷期が到来する兆候にも似ているという。 太陽には南北両極にプラス極とマイナス極があり、約11年周期で同時に両極の磁場が入れ替わる(反転する）。現在の太陽は北極がマイナス極、南極がプラス極となっていて、次回は2013年5月の太陽活動の「極大期」(太陽の黒点数が最大になる時期)と同時に反転すると予測されていた。 ところが今年1月の太陽観測衛星「ひので」の観測で、北極では約1年も早く、反転に向けて磁場がゼロ状態に近くなっていることが分かった。しかし、南極では反転の兆しはみられず、依然、プラス極のままだ。その結果、北極と南極がともにプラス極となり、赤道付近に別のマイナス極ができるような、太陽全体の磁場が「4重極構造」になる可能性があるという。 太陽活動は極大期と極小期を
