DNA tests of illegal ivory link multiple ivory shipments to same dealers

Sep 19 2018 - 00:09
In a paper published Sept. 19 in the journal Science Advances, an international team led by scientists at the University of Washington reports that DNA test results of large ivory seizures made by law enforcement have linked multiple ivory shipments over the three-year period, when this trafficking reached its peak, to the same network of dealers operating out of a handful of African ports.

'Robotic Skins' turn everyday objects into robots

Sep 19 2018 - 00:09
When you think of robotics, you likely think of something rigid, heavy, and built for a specific purpose. New 'Robotic Skins' technology developed by Yale researchers flips that notion on its head, allowing users to animate the inanimate and turn everyday objects into robots.

New research identifies abundant endangered fish below waterfall in San Juan River

Sep 19 2018 - 00:09
A new study published in the journal River Research and Applications provides insight into the magnitude of the effect this waterfall has on endangered fishes in the San Juan River. From 2015-2017 more than 1,000 razorback sucker and dozens of Colorado pikeminnow were detected downstream of the waterfall. Some fish moved to this location from up to 600 miles away in the Colorado River.

Women who breastfeed for at least five months have more kids

Sep 19 2018 - 00:09
Cornell University professor of sociology Vida Maralani found in new research that women who breastfeed their first child for five months or longer are more likely to have three of more children, and less likely to have only one child.

A little labeling goes a long way

Sep 19 2018 - 00:09
New research from Northwestern University reveals that infants can use even a few labeled examples to spark the acquisition of object categories. Those labeled examples lead infants to initiate the process of categorization, after which they can integrate all subsequent objects, labeled or unlabeled, into their evolving category representation.

People can handle the truth (more than you think)

Sep 19 2018 - 00:09
New research from the University of Chicago Booth School of Business explores the consequences of honesty in everyday life and determines that people can often afford to be more honest than they think.

Firmware at the blink of an eye: Scientists develop new technology of alloy steel rolling

Sep 19 2018 - 00:09
A research team from the NUST MISIS Department of Pressure Metal Treatment has developed a new technology which simplifies the process of hot rolling seamless pipes made of alloy and high-alloy steel. The consistent use of two simple male punches, tools that turn an unruly steel blank into a hollow "sleeve", is a distinctive feature of the technology.

if pigeons were brilliant, would they flock?

Sep 19 2018 - 00:09
UC Davis researcher looked at how people behave in simple reasoning games and found that people are usually driven to 'flock,' or behave similarly to others in a given situation.

Gaia detects a shake in the Milky Way

Sep 19 2018 - 00:09
A team led by researchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB, UB-IEEC) and the University of Groningen has found, through the analysis of Gaia data, substructures which were unknown so far in the Milky Way. The findings, which appeared when combining positions and speed of six million stars from our galaxy's disk, have been published in the journal Nature.

How long does a quantum jump take?

Sep 19 2018 - 00:09
Quantum jumps are usually regarded to be instantaneous. However, new measurement methods are so precise that it has now become possible to observe such a process and to measure its duration precisely -- for example the famous 'photoelectric effect', first described by Albert Einstein.

New nanoparticle superstructures made from pyramid-shaped building blocks

Sep 19 2018 - 00:09
In research that may help bridge the divide between the nano and the macro, Brown University chemists have used pyramid-shaped nanoparticles to create what might be the most complex macroscale superstructure ever assembled.

Team of researchers determines absolute duration of photoelectric effect for the first time

Sep 19 2018 - 00:09
It provides the basis for solar energy and global communications: the photoelectric effect. Albert Einstein described it over a century ago. For the first time, scientists from the Technical University of Munich (TUM), the Max-Planck Institute of Quantum Optics (MPQ), and the TU Wien have now measured the absolute duration of the light absorption and of the resulting photoelectron which is released from a solid body.

Moderate warming could melt East Antarctic Ice Sheet

Sep 19 2018 - 00:09
Parts of the world's largest ice sheet would melt if Antarctic warming of just 2°C is sustained for millennia, according to international research.University of Queensland scientist Dr Kevin Welsh was part of a team that used evidence from warm periods in Earth's history to see how the East Antarctic Ice Sheet might react to a warming climate.

Diverse forests are stronger against drought

Sep 19 2018 - 00:09
In a paper published in Nature, researchers including University of Utah biologist William Anderegg report that forests with trees that employ a high diversity of traits related to water use suffer less of an impact from drought. The results, which expand on previous work that looked at individual tree species' resilience based on hydraulic traits, lead to new research directions on forest resilience and inform forest managers working to rebuild forests after logging or wildfire.

Zombie cells found in brains of mice prior to cognitive loss

Sep 19 2018 - 00:09
Zombie cells are the ones that can't die but are equally unable to perform the functions of a normal cell. These zombie, or senescent, cells are implicated in a number of age-related diseases. And with a new letter in Nature, Mayo Clinic researchers have expanded that list.

Characterization of pregnancy microbiome reveals variations in bacterial diversity

Sep 19 2018 - 00:09
In a study published today in Genome Research, researchers performed detailed whole-community sequencing on the microbial communities of three maternal body sites (vagina, gut, and oral cavity) over the course of pregnancy from the first trimester through delivery revealing variations in bacterial diversity.

UMN researchers discover influenza virus doesn't replicate equally in all cells

Sep 19 2018 - 00:09
The seasonal flu is caused by different subtypes of Influenza A virus and typically leads to the death of half a million people each year. In order to better understand this virus and how it spreads, University of Minnesota Medical School researchers took a closer look at the cells inside the lungs. What they discovered is not only is the immune system response tuned to the amount of virus replication, it's also tuned to the viral spread.
