New species of tree living crab found in Western Ghats

An article reveals a new genus and new species of tree crab in Kerala, southern India. Known scientifically as the ‘Kani maranjandu,’ it is substantially different from other congeners. Its distinguishing characters include: the structure of its hard upper shell, as well as its male abdominal structure and reproductive parts, and of course, its diagnostic elongated walking legs, which no other genus has. …

A ‘bionic leaf’ could help feed the world

In the second half of the 20th century, an agricultural boom called the ‘green revolution’ was largely credited with averting a global food crisis. Now, the problem of feeding the world’s growing population looms again. To help address the challenge, researchers have presented a ‘bionic’ leaf that uses bacteria, sunlight, water and air to make fertilizer in the very soil where crops are grown.

Altering the immune system to reverse paralysis

In the ultimate betrayal, one’s own immune system can turn against the protective sheath that envelops neurons in the brain, leaving the body paralyzed. Researchers have developed an experimental treatment that tames the wayward immune system in rodents, returning the power of movement to paralyzed mice. The approach may someday combat autoimmune diseases in humans. …

Tyrannosaurs show their sensitive side

A team of researchers has found a new species of tyrannosaur dinosaur — the most popular of the prehistoric creatures. After the fossils were pulled out of the muddy banks of a Montana river, the team was able to analyze the texture of the facial bones of the new species. The findings suggest that the face of tyrannosaurs was covered in a scaly protective layer with a high degree of tactile sensitivity, similar to crocodiles. …

How do plants make oxygen? Ask cyanobacteria

Researchers reveal the family tree of the group of microorganisms responsible for ‘inventing’ the oxygen-producing photosynthesis that lets you breathe. They added the genomes of 41 uncultured microorganisms, which helped to pin down the precise point in the evolution of cyanobacteria at which oxygenic photosynthesis arose.

Aging: Cell coordination breakdown

Scientists have resolved a key question in aging research by showing how mouse immune cells of different ages respond to stimulation. Study demonstrates weaker response of older cells is due to their coordination breaking down, making their response to immune stimulation more variable. Single-cell sequencing technology allows scientists to profile individual cells independently to view cellular activity in high resolution. …
