The Newton Museum is closing, and everything's gotta go. Plus:IPod tops Google's shopping search list. From Leander Kahney's Cult of Mac blog. There's No Scent Like Home: New Research Shows Larval Fish Use Smell T
New research from MBL scientists and their colleagues shows that some fish larvae can discriminate odors in ocean currents and use scent to return to the reefs where they were born. The olfactory imprinting of natal reefs sheds light on how such a wide diversity of species arose. The homing behavior of reef fishes, the researchers contend, could support population isolation and genetic divergence that may ultimately lead to the formation of new species. Early Voters Hold Most Power In Primaries, Say Economists
As voters in Iowa and New Hampshire prepare to head to the polls for the 2008 presidential primary season, new research shows just how much power these early voters hold. Researchers demonstrate that early voters have up to 20 times the influence of voters in later states when it comes to candidate selection. Comparing Chimp, Human DNA
Most of the big differences between human and chimpanzee DNA lie in regions that do not code for genes, according to a new study. Instead, they may contain DNA sequences that control how gene-coding regions are activated and read. Low Folate Diets Found To Increase Risk Of Colorectal Cancer
A new study by scientists at the MUHC has revealed that a diet low in folate may increase the risk of developing colorectal cancer. Published in the scientific journal Cancer Research today, the study not only illustrates a way to prevent the disease but also provides further insight into the mechanisms of the disease, which could lead to novel therapies. Human's Ecological Footprint In 2015 And Amazonia Revealed
In the February issue of Frontiers in Ecology and the Environment, a recent study shows human population size and affluence are the main drivers of human-caused environmental stressors, while urbanization, economic structure and age of population have little effect. In a review in the same issue, researchers review newly revealed changes in the Amazon rainforests and the ecosystem services they provide. Moonbeams Shine On Einstein, Galileo And Newton
Thirty-five years after Moon-walking astronauts placed special reflectors on the lunar surface, scientists have used these devices to test Albert Einstein's general theory of relativity to unprecedented accuracy. The findings, which also confirm theories from Galileo Galilei and Isaac Newton, may help to explain physical laws of the universe and benefit future space missions. Origin Of 'Breathable'Atmosphere Half A Billion Years Ago Discovered
Geologists have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today. The study suggests that upheavals in the earth's crust initiated a kind of reverse-greenhouse effect 500 million years ago that cooled the world's oceans, spawned giant plankton blooms and sent a burst of oxygen into the atmosphere. Iron-deficient Infants Have Lower Cognitive Scores At 19, Especially I
Costa Rican teens who were iron-deficient as infants continue to lag behind their peers in cognitive test scores, with a wider gap for children at lower socioeconomic levels, according to study results published in the November issue of Archives of Pediatrics &Adolescent Medicine, one of the JAMA/Archives journals. Atom Camera? Helium Atoms Sent By Nozzle May Light Way For New Imaging
A newly devised nozzle fitted with a pinhole-sized capillary has allowed researchers to distribute helium atoms with X-ray-like waves on randomly shaped surfaces. The technique could power the development of a new microscope for nanotechnology, allowing for a non-invasive, high-resolution approach to studying both organic and inorganic materials.
