Baby's innate number sense predicts future math skill Posted: 22 Oct 2013 02:08 PM PDT A new study suggests that the strength of an infant's innate sense of numerical quantities can be predictive of that child's mathematical abilities three years later.

Model plant misled scientists about multicellular growth Posted: 22 Oct 2013 08:35 AM PDT Scientists have misunderstood one of the most fundamental processes in the life of plants because they have been looking at the wrong flower, according to researchers.

Long-sought pattern of ancient light detected Posted: 22 Oct 2013 07:10 AM PDT The journey of light from the very early universe to modern telescopes is long and winding. The ancient light traveled billions of years to reach us, and along the way, its path was distorted by the pull of matter, leading to a twisted light pattern. This twisted pattern of light, called B-modes, has at last been detected. The discovery, which will lead to better maps of matter across our universe, was made using the National Science Foundation's South Pole Telescope, with help from the Herschel space observatory.

High school student discovers skeleton of baby dinosaur Posted: 22 Oct 2013 06:17 AM PDT A chance find by a high school student led to the youngest, smallest and most complete fossil skeleton yet known from the iconic tube-crested dinosaur Parasaurolophus. The discovery shows that the prehistoric plant-eater sprouted its strange headgear before it celebrated its first birthday. Three-dimensional scans of nearly the entire fossil are available online, making this the most digitally accessible dinosaur to date.

Genome of aggressive lymphoma sequenced Posted: 22 Oct 2013 06:16 AM PDT Mantle cell lymphoma is a very aggressive and difficult-to-treat cancer originated in blood cells and lymph nodes. To identify the molecular alterations responsible for this tumor, and facilitate the development of new treatments, a team of scientists has sequenced the genomes of over 30 of lymphomas. The result of this work presents the first comprehensive genomic analysis of this disease.

Growing up poor, stressed impacts brain function as adult Posted: 21 Oct 2013 06:14 PM PDT Poverty, coupled with stress, has long-lasting effects on brain function, according to a new study. Researchers found that test subjects who had lower family incomes at age 9 exhibited, as adults, greater activity in the amygdala, an area in the brain known for its role in fear and other negative emotions. These individuals showed less activity in areas of the prefrontal cortex, an area in the brain thought to regulate negative emotion.

Single mutation gives virus new target Posted: 21 Oct 2013 01:26 PM PDT A mutation as minute as swapping just one amino acid can completely change the target that a virus will bind to on a victim cell -- potentially shifting what kind of cell and eventually what kind of organism a virus could infect.
