울지않는늑대 썸네일형 리스트형 Better Protein Creation May Be Secret of Longevity for the World's Longest-Living Rodent Better Protein Creation May Be Secret of Longevity for the World's Longest-Living Rodent Sep. 30, 2013 — Naked mole rats have what any animal would want. They live long lives -- about 30 years -- and stay healthy until the very end. Now biologists at the University of Rochester have new insights into the animal's longevity -- better-constructed proteins. Proteins are involved in nearly all funct.. 더보기 Sieving Through 'Junk' DNA Reveals Disease-Causing Genetic Mutations Sieving Through 'Junk' DNA Reveals Disease-Causing Genetic Mutations Oct. 3, 2013 — Scientists have revealed nearly 100 genetic variants implicated in the development of cancers such as breast cancer and prostate cancer. The new method designed by the team, described in the journal Science, identified these variants in the under-explored regions of DNA that do not code for proteins, but instead .. 더보기 Cold, Salty and Promiscuous: Gene-Shuffling Microbes Dominate Antarctica's Deep Lake Cold, Salty and Promiscuous: Gene-Shuffling Microbes Dominate Antarctica's Deep Lake Sep. 30, 2013 — Sequestered in Antarctica's Vestfold Hills, Deep Lake became isolated from the ocean 3,500 years ago by the Antarctic continent rising, resulting in a saltwater ecosystem that remains liquid in extreme cold, and providing researchers a unique niche for studying the evolution of the microbes that .. 더보기 Chemists Slide a Splitting Catalyst Over DNA for First Time Chemists Slide a Splitting Catalyst Over DNA for First Time Sep. 24, 2013 — Chemists from Nijmegen have developed a catalyst that binds to DNA, slides over it and splits the molecule in particular places. The researchers were able to do this by synthetically modifying a natural catalyst. This finding is a first in the field of chemistry and will help in the selective modification of polymers suc.. 더보기 Tiger Genome Sequenced: Tiger, Lion and Leopard Genomes Compared Tiger Genome Sequenced: Tiger, Lion and Leopard Genomes Compared Sep. 20, 2013 — An international team led by South Korea's Personal Genomics Institute and BGI unraveled the first whole genome of a 9-year-old male Amur tiger (Panthera tigris altaica), and compared it with the genomes of other big cats including the white Bengal tiger, lions, and snow leopards. The genomic data from this study pr.. 더보기 Arctic Sea Ice Minimum in 2013 Is Sixth Lowest On Record Arctic Sea Ice Minimum in 2013 Is Sixth Lowest On Record Sep. 21, 2013 — After an unusually cold summer in the northernmost latitudes, Arctic sea ice appears to have reached its annual minimum summer extent for 2013 on Sept. 13, the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder has reported. Analysis of satellite data by NSIDC and NASA showed t.. 더보기 Origins of Genomic 'Dark Matter' Discovered Origins of Genomic 'Dark Matter' Discovered Sep. 18, 2013 — A duo of scientists at Penn State University has achieved a major milestone in understanding how genomic "dark matter" originates. This "dark matter" -- called non-coding RNA -- does not contain the blueprint for making proteins and yet it comprises more than 95 percent of the human genome. The researchers have discovered that essential.. 더보기 Toxoplasma Infection Permanently Shifts Balance in Cat and Mouse Game Toxoplasma Infection Permanently Shifts Balance in Cat and Mouse Game Sep. 18, 2013 — The Toxoplasma parasite can be deadly, causing spontaneous abortion in pregnant women or killing immune-compromised patients, but it has even stranger effects in mice. Infected mice lose their fear of cats, which is good for both cats and the parasite, because the cat gets an easy meal and the parasite gets int.. 더보기 Dating of Beads Sets New Timeline for Early Humans Dating of Beads Sets New Timeline for Early Humans Sep. 13, 2013 — An international team of researchers led by Oxford University have new dating evidence indicating when the earliest fully modern humans arrived in the Near East, the region known as the Middle East today. They have obtained the radiocarbon dates of marine shell beads found at Ksar Akil, a key archaeological site in Lebanon, which.. 더보기 이전 1 2 3 4 5 6 7 ··· 10 다음
