Are plants intelligent? It depends on the definition      (via sciencedaily.com)     Original source 

Goldenrod can perceive other plants nearby without ever touching them, by sensing far-red light ratios reflected off leaves. When goldenrod is eaten by herbivores, it adapts its response based on whether or not another plant is nearby. Is this kind of flexible, real-time, adaptive response a sign of intelligence in plants?

New technique reveals earliest signs of genetic mutations      (via sciencedaily.com)     Original source 

Mutations are changes in the molecular 'letters' that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including cancer. Now, a new study introduces an original technique, called HiDEF-seq, that can accurately detect the early molecular changes in DNA code that precede mutations.

3D-printed mini-actuators can move small soft robots, lock them into new shapes      (via sciencedaily.com)     Original source 

Researchers have demonstrated miniature soft hydraulic actuators that can be used to control the deformation and motion of soft robots that are less than a millimeter thick. The researchers have also demonstrated that this technique works with shape memory materials, allowing users to repeatedly lock the soft robots into a desired shape and return to the original shape as needed.

Soil bacteria respire more CO2 after sugar-free meals      (via sciencedaily.com)     Original source 

Researchers tracked how plant matter moves through bacteria's metabolism. Microbes respire three times as much carbon dioxide (CO2) from non-sugar carbons from lignin compared to sugar from cellulose. Although microbes consume both types of plant matter at the same time, each type enters a different metabolic pathway. Findings could improve predictions of how climate-dependent changes in soil carbon types will affect microbial CO2 production.

Virus-like nanoparticles control the multicellular organization and reproduction of host bacteria      (via sciencedaily.com)     Original source 

Researchers have discovered that virus-like nanoparticles can promote the multicellular organization and reproduction of host bacteria. These particles, which are evolutionarily related to phages (viruses that infect bacteria), contain an enzyme that helps shape the multicellular architecture and ultimately enhances morphological differentiation.

Researchers create realistic virtual rodent      (via sciencedaily.com)     Original source 

To help probe the mystery of how brains control movement, scientists have created a virtual rat with an artificial brain that can move around just like a real rodent. The researchers found that activations in the virtual control network accurately predicted neural activity measured from the brains of real rats producing the same behaviors.

Scientists unlock secrets of how archaea, the third domain of life, makes energy      (via sciencedaily.com)     Original source 

An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings explain how these tiny lifeforms make energy by consuming and producing hydrogen. This simple but dependable strategy has allowed them to thrive in some of Earth's most hostile environments for billions of years.

Trash-sorting robot mimics complex human sense of touch      (via sciencedaily.com)     Original source 

Researchers are breaking through the difficulties of robotic recognition of various common, yet complex, items. Their layered sensor is equipped with material detection at the surface and pressure sensitivity at the bottom, with a porous middle layer sensitive to thermal changes. An efficient cascade classification algorithm rules out object types in order, from easy to hard, starting with simple categories like empty cartons before moving on to orange peels or scraps of cloth.

Lazy predator: A new species of mountain pitviper from China      (via sciencedaily.com)     Original source 

Researchers have discovered a new species of medium-sized venomous snake in Yunnan, China. Ovophis jenkinsi is dark brownish-grey in color with trapezoidal patches on its back. It is endemic to China's Yingjiang County and is not difficult to find in the wild. In the future, researchers plan to collect more information about this new species, including its appearance, distribution, and habits.

First week after birth is critical for development of senses      (via sciencedaily.com)     Original source 

Researchers have found that the maturation of the senses for smell and touch is closely linked in mice and that this strong interaction takes place within a narrow developmental time window. These findings not only underline the importance of environmental stimuli for brain assembly in early life, but also the interdependent development of the senses.
