Why can't robots outrun animals?      (via sciencedaily.com)     Original source 

Robotics engineers have worked for decades and invested many millions of research dollars in attempts to create a robot that can walk or run as well as an animal. And yet, it remains the case that many animals are capable of feats that would be impossible for robots that exist today.

Researchers show it's possible to teach old magnetic cilia new tricks      (via sciencedaily.com)     Original source 

Magnetic cilia -- artificial hairs whose movement is powered by embedded magnetic particles -- have been around for a while, and are of interest for applications in soft robotics, transporting objects and mixing liquids. However, existing magnetic cilia move in a fixed way. Researchers have now demonstrated a technique for creating magnetic cilia that can be 'reprogrammed,' changing their magnetic properties at room temperature to change the motion of the cilia as needed.

World's chocolate supply threatened by devastating virus      (via sciencedaily.com)     Original source 

A rapidly spreading virus threatens the health of the cacao tree and the dried seeds from which chocolate is made, jeopardizing the global supply of the world's most popular treat. Researchers have developed a new strategy: using mathematical data to determine how far apart farmers can plant vaccinated trees to prevent mealybugs from jumping from one tree to another and spreading the virus.

How 3D printers can give robots a soft touch      (via sciencedaily.com)     Original source 

Soft skin coverings and touch sensors have emerged as a promising feature for robots that are both safer and more intuitive for human interaction, but they are expensive and difficult to make. A recent study demonstrates that soft skin pads doubling as sensors made from thermoplastic urethane can be efficiently manufactured using 3D printers.

Plant sensors could act as an early warning system for farmers      (via sciencedaily.com)     Original source 

Using a pair of sensors made from carbon nanotubes, researchers discovered signals that help plants respond to stresses such as heat, light, or attack from insects or bacteria. Farmers could use these sensors to monitor threats to their crops, allowing them to intervene before the crops are lost.

Making crops colorful for easier weeding      (via sciencedaily.com)     Original source 

To make weeding easier, scientists suggest bioengineering crops to be colorful or to have differently shaped leaves so that they can be more easily distinguished from their wild and weedy counterparts. This could involve altering the crops' genomes so that they express pigments that are already produced by many plants, for example, anthocyanins, which make blueberries blue, or carotenoids, which make carrots orange. Then, they say, weeding robots could be trained to remove only the weeds using machine learning.

Seed ferns: Plants experimented with complex leaf vein networks 201 million years ago      (via sciencedaily.com)     Original source 

According to a research team led by palaeontologists, the net-like leaf veining typical for today's flowering plants developed much earlier than previously thought, but died out again several times. Using new methods, the fossilized plant Furcula granulifer was identified as such an early forerunner. The leaves of this seed fern species already exhibited the net-like veining in the late Triassic (around 201 million years ago).

Twisted pollen tubes induce infertility      (via sciencedaily.com)     Original source 

Plants with multiple sets of chromosomes, known as polyploids, are salt-tolerant or drought-resistant and often achieve higher yields. However, newly formed polyploid plants are often sterile or have reduced fertility and are unsuitable for breeding resistant lines. The reason is that the pollen tube in these plants grows incorrectly, which keeps fertilization from taking place. Pollen tube growth is mainly controlled by two genes that could be useful in crop breeding.

Tropical forests can't recover naturally without fruit-eating birds      (via sciencedaily.com)     Original source 

Natural forest regeneration is hailed as a cost-effective way to restore biodiversity and sequester carbon. However, the fragmentation of tropical forests has restricted the movement of large birds limiting their capacity to disperse seeds and restore healthy forests.
