Research finds naps plus sleep may enhance emotional memory in early childhood

For children in this study, the authors write that 'individually, the nap and overnight sleep bouts were not sufficient to induce changes in memory. A significant benefit of napping was observed only when changes across the entire 24-hour period were considered. This supports an interplay between the nap and subsequent overnight sleep in the consolidation of memories in young children.'

DNA and RNA are naturally polarised molecules. Scientists believe that these molecules have an in-built polarity that can be reoriented or reversed fully or in part under an electric field. In a new study published in EPJ E, See-Chuan Yam from the University of Malaya, Kuala Lumpur, Malaysia, and colleagues show that all the DNA and RNA building blocks, or nucleobases, exhibit a non-zero polarisat

How do muscles know what time it is?

How do muscle cells prepare for the particular metabolic challenges of the day? Scientists at Helmholtz Zentrum München and Ludwig-Maximilians-Universität München (LMU), members of the German Center for Diabetes Research (DZD), have investigated this question and published their results in 'PLOS Biology'. The study has uncovered a metabolic network which is, contrary to expectations, not controlle

A materials scientist's dream come true

Materials can deform plastically by atomic-scale line defects called dislocations. Many technical applications are based on this fundamental process, such as forging, but we also rely on the power of dislocations in our everyday life: in the crumple zone of cars dislocations protect lives by transforming energy into plastic deformation. FAU researchers have now found a way of manipulating individu

In eastern US, adult trees adapt and acclimate to local climate

Trees growing in temperate forests in the eastern US show strong adaptation or acclimation to local climate. So reports a new study that analyzed more than 23,000 tree cores to investigate how adult trees respond to changes in climatic conditions. Results were published this week in the journal Ecosphere.

Soil hasn’t recovered from ancient Maya cutting down trees

The Maya civilization’s deforestation decimated carbon reservoirs in the tropical soils of the Yucatán peninsula region long after people abandoned ancient cities and the forests grew back, according to a new study. The new findings, which appears in the journal Nature Geoscience , underscore how important soils and our treatment of them could be in determining future levels of greenhouse gases i

Study shows indigenous Canadian Arctic people's textiles predated European contact

A new study by Brown University researchers shows that the Dorset and Thule people—ancestors of today's Inuit—created spun yarn some 500 to 1,000 years before Vikings arrived in North America. The finding, made possible in part by a new method for dating fiber artifacts contaminated with oil, is evidence of independent, homegrown indigenous fiber technology rather than a transfer of knowledge from

How the brain suppresses the act of revenge

Researchers from UNIGE have developed an economic game in which a participant is confronted with the fair behaviour of one player and the unfair provocations of another player. They observed which areas were activated as the participant experienced unfairness and anger. Then scientists gave the participant the opportunity to take revenge. They thus identified the location in the brain of activatio

Galaxies abound in this spectacular Hubble image; spiral arms swirl in all colors and orientations, and fuzzy ellipticals can be seen speckled across the frame as softly glowing smudges on the sky. Each visible speck of a galaxy is home to countless stars. A few stars closer to home shine brightly in the foreground, while a massive galaxy cluster nestles at the very center of the image—an immense

How cells remember their jobs during division

Researchers have developed a technique that offers new insight into “cellular memory.” The cells in our body divide constantly throughout life. But how do cells remember whether to develop into a skin, liver, or intestinal cell? It’s a question that has puzzled scientists for many years. With the new research, scientists have come a little closer to understanding the process. Using the technique,

Optogenetics – controlling neurons with light – may lead to cures for PTSD, Alzheimer's

Through the emerging field of optogenetics, a technology that allows genetically modified neurons in living tissue to be precisely controlled by means of light, scientists are attempting to gain a better understanding of how the brain works in hopes of discovering cures for debilitating neural disorders such as post-traumatic stress disorder (PTSD) and Alzheimer's disease.

Ecosystems are getting greener in the Arctic

In recent decades, scientists have noted a surge in Arctic plant growth as a symptom of climate change. But without observations showing exactly when and where vegetation has bloomed as the world's coldest areas warm, it's difficult to predict how vegetation will respond to future warming. Now, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and

This new data revealed that Antarctica fused into one plate around 11 million years ago, roughly 15 million years later than previously assumed.
