Study In Babies Says Knowing Good People From Bad May Be Biological

Study In Babies Says Knowing Good People From Bad May Be Biological

In the first evidence of its kind to date, Yale researchers find that infants prefer individuals who help others to those who either do nothing, or interfere with others’ goals, it is reported today in Nature.
“This supports the view that our ability to evaluate people is a biological adaptation—universal and unlearned,” said the authors of the study.
The study included six-and-10-month-old babies whose preferences were determined by recording which of two actors they reached towards.
In the first experiment, infants saw a wooden character with large glued-on eyes known as “The Climber.” At first, the climber rested at the bottom of a hill.

Connecting Wind Farms To Each Other Can Make It More Reliable, Says Study

Connecting Wind Farms To Each Other Can Make It More Reliable, Says Study

Stanford University scientists say they can make wind power a steady, dependable source of electricity but it will require connecting wind farms throughout a given geographic area with new transmission lines, always a difficult sell for people who live in the affected area. The findings are published in the November Journal of Applied Meteorology and Climatology.
Wind is the world’s fastest growing electric energy source, say Cristina Archer and Mark Jacobson. but because it is intermittent it is not used to supply baseload electric power today. Baseload power is the amount of steady and reliable electric power that is constantly being produced, typically by power plants, regardless of the electricity demand.

Study: Not Just Global Warming, But Global Warring, If The Past Is An Indicator

Study: Not Just Global Warming, But Global Warring, If The Past Is An Indicator

Global cooling caused wars and migration in the past and global warming could do the same in the future, according to a study in Proceedings of the National Academy of Sciences (PNAS).
As temperatures decreased centuries ago during a period called the Little Ice Age, the number of wars increased, famine occurred and the population declined.
“Even though temperatures are increasing now, the same resulting conflicts may occur since we still greatly depend on the land as our food source,” said Peter Brecke, associate professor in the Georgia Institute of Technology’s Sam Nunn School of International Affairs and co-author of the study.

Discovery: Ancient Galilee Synagogue Reveals Unique Mosaic Floor

Discovery: Ancient Galilee Synagogue Reveals Unique Mosaic Floor

Remains of an ancient synagogue from the Roman-Byzantine era have been revealed in excavations carried out in the Arbel National Park in the Galilee under the auspices of the Hebrew University of Jerusalem.
The excavations, in the Khirbet Wadi Hamam, were led by Dr. Uzi Leibner of the Hebrew University’s Institute of Archaeology and Scholion – Interdisciplinary Research Center in Jewish Studies.
Dr. Leibner said that the synagogue’s design is a good example of the eastern Roman architectural tradition. A unique feature of the synagogue is the design of its mosaic floor, he said.

Mosaic floor found at site of newly discovered Galilee synagogue shows workman with woodworking tool.

Sculptures: Beauty Is In The Brain, Not The Eye, Of The Beholder

Sculptures: Beauty Is In The Brain, Not The Eye, Of The Beholder

Is there an objective biological basis for the experience of beauty in art? Or is aesthetic experience entirely subjective? This question has been addressed in a paper by Cinzia Di Dio, Emiliano Macaluso and Giacomo Rizzolatti. The researchers used fMRI scans to study the neural activity in subjects with no knowledge of art criticism, who were shown images of Classical and Renaissance sculptures.
The ‘objective’ perspective was examined by contrasting images of Classical and Renaissance sculptures of canonical proportions, with images of the same sculptures whose proportions were altered to create a comparable degraded aesthetic value.

Extinct Eurypterid Fossil Shows It Was Bigger Than A Grown Man

Extinct Eurypterid Fossil Shows It Was Bigger Than A Grown Man

The discovery of a giant fossilised claw from an ancient sea scorpion indicates that when alive it would have been about two and a half meters long, much taller than the average man.
This find, from rocks 390 million years old, suggests that spiders, insects, crabs and similar creatures were much larger in the past than previously thought.
Dr Simon Braddy from the Department of Earth Sciences at the University of Bristol, co-author of an article about the find, said, ‘This is an amazing discovery.

Discovery: How The Middle Temporal Region Controls What Eyes See

Discovery: How The Middle Temporal Region Controls What Eyes See

Vase or face? When presented with the well known optical illusion in which we see either a vase or the faces of two people, what we observe depends on the patterns of neural activity going on in our brains.
“In this example, whether you see faces or vases depends entirely on changes that occur in your brain, since the image always stays exactly the same,” said John Serences, a UC Irvine cognitive neuroscientist.
In a recent study published in the Journal of Neuroscience, Serences and co-author Geoffrey Boynton, associate professor at the University of Washington, found that when viewing ambiguous images such as optical illusions, patterns of neural activity within specific brain regions systematically change as perception changes.

American Geographical Society Library Shows Rare Cartography Secrets

American Geographical Society Library Shows Rare Cartography Secrets

Whales were the economic drivers of the 1850s. So important was this resource that the founder of the U.S. Oceanographic Office, Matthew Fontaine Maury, created a map showing the worldwide distribution of sperm and right whales in 1851.
“Whale oil then was like petroleum is today,” says Christopher Baruth. “This is a graphic device that showed where the whales were located by type and season.”
Baruth is curator of the American Geographical Society (AGS) Library, where a copy of the whale map is one of thousands of rare cartographical materials and geographical photographs.

The Mappamundi, the oldest original map in the AGSL holdings, was produced in 1452 by the Venetian cartographer Giovanni Leardo.

Genome Comparison Discovers 300 Previously Unknown Human Genes

Genome Comparison Discovers 300 Previously Unknown Human Genes

Using supercomputers to compare portions of the human genome with those of other mammals, researchers at Cornell have discovered some 300 previously unidentified human genes, and found extensions of several hundred genes already known.
The discovery is based on the idea that as organisms evolve, sections of genetic code that do something useful for the organism change in different ways.
The research is reported by Adam Siepel, Cornell assistant professor of biological statistics and computational biology, Cornell postdoctoral researcher Brona Brejova and colleagues at several other institutions in the journal Genome Research.

Shinya Yamanaka Reprograms Human Adult Cells To Function Like Embryonic Stem Cells

Shinya Yamanaka Reprograms Human Adult Cells To Function Like Embryonic Stem Cells

Acclaimed stem cell researcher Shinya Yamanaka, MD, PhD, has reported that he and his Kyoto University colleagues have successfully reprogrammed human adult cells to function like pluripotent embryonic stem (ES) cells. Because it circumvents much of the controversy and restrictions regarding generation of ES cells from human embryos, this breakthrough, reported in the journal Cell, should accelerate the pace of stem cell research.
Last year, Yamanaka, who is also a senior investigator at the Gladstone Institute of Cardiovascular Disease (GICD), reported that he and his Kyoto colleagues had reprogrammed mouse skin cells into pluripotent stem cells, laying the foundation to apply this methodology in human cells.

Research Without Drama? Turning Skin Cells Into Faux Embryonic Stem Cells

Research Without Drama? Turning Skin Cells Into Faux Embryonic Stem Cells

There's always been speculation that human embryonic stem cell research was not worth the controversy due to uncertainty about their value in research and objections from womens' rights groups on one side and right-to-life groups on the other.
Pluripotent cell lines from a non-embryonic source would seem to satisfy everyone
By introducing four genes into human fibroblasts,researchers can transform adult human skin cells into cells that resemble embryonic stem cells, researchers report in Cell. The converted cells have many of the physical, growth and genetic features typically found in embryonic stem cells and can differentiate to produce other tissue types, including neurons and heart tissue, according to the researchers.

Bioethicist:  Latest Stem Cell Research Removes Ethical Issues

Bioethicist: Latest Stem Cell Research Removes Ethical Issues

To derive embryonic stem cells, it is necessary to remove critical cells from an embryo, resulting in its destruction. That triggers opposition from right-to-life critics of the research, who cite moral and ethical concerns.
The research has also generated opposition from some members of the women's movement who object the use of stimulating drugs in women who agree to donate eggs for cloning research aimed at creating specialized embryonic stem cell lines.
Recent research has the potential to render both of those objections moot, since it showed that introducing four genes into cells derived from skin cells, called human fibroblasts, resulted in cells that essentially share all the features of embryonic stem cells - but without using or destroying embryos.
