Humpbacks are among animals who manufacture and wield tools      (via sciencedaily.com)     Original source 

Researchers suggest a new designation of the humpback whales they study: tool wielders. Researchers have known that humpback whales create "bubble-nets" to hunt, but they have learned that the animals don't just create the bubble-nets; they manipulate this unique tool in a variety of ways to maximize their food intake in Alaskan feeding grounds.

'Masters of shape-shifting': How darkling beetles conquered the world      (via sciencedaily.com)     Original source 

Large-scale genomic analysis of darkling beetles, a hyper-diverse insect group of more than 30,000 species worldwide, rolls back the curtain on a 150-million-year evolutionary tale of one of Earth's most ecologically important yet inconspicuous creatures, according to new research.

Researchers uncover the secrets of 'plant puberty'      (via sciencedaily.com)     Original source 

Researchers have identified the genetic changes linked to why plants go through a developmental change similar to 'puberty' at different rates, a discovery which could lead to better crop nutrition.

Analyzing 'Finnegans Wake' for novel spacing between punctuation marks      (via sciencedaily.com)     Original source 

James Joyce's tome 'Finnegans Wake' famously breaks the rules of normal prose through its unusual, dreamlike stream of consciousness, and new work in chaos theory takes a closer look at how Joyce's challenging novel stands out mathematically. Researchers compared the distribution of punctuation marks in various experimental novels to determine the underlying order of 'Finnegans Wake' and by statistically analyzing the texts, researchers found the tome exhibits an unusual but statistically identifiable structure. The wide singularity spectrum was perfectly symmetrical, meaning sentence length variability follows an orderly curve.

Spectacular increase in the deuterium/hydrogen ratio in Venus' atmosphere      (via sciencedaily.com)     Original source 

Our understanding of Venus' water history and the potential that it was once habitable in the past is being challenged by recent observations.

Evidence stacks up for poisonous books containing toxic dyes      (via sciencedaily.com)     Original source 

Some of the attractive hues of brightly colored, cloth-bound books from the Victorian era come from dyes that could pose a health risk to readers, collectors or librarians. The latest research on these 'poison books' used three techniques -- including one that hasn't previously been applied to books -- to assess dangerous dyes in a university collection and found some volumes had levels that might be unsafe.

Study explains why laws are written in an incomprehensible style      (via sciencedaily.com)     Original source 

A new study on 'legalese' suggests this convoluted language acts to convey a sense of authority in legal documents. The researchers also found that even non-lawyers use legalese when asked to write laws.

How 'winner and loser effects' impact social rank in animals -- and humans      (via sciencedaily.com)     Original source 

A new article provides a narrative review of the relevant similarities and distinctions between nonhumans and humans to assess the causes and consequences of winner and loser effects in humans.

Searching old stem cells that stay young forever      (via sciencedaily.com)     Original source 

The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists have now identified possible candidates for multipotent stem cells in the sea anemone for the first time. These stem cells are regulated by evolutionary highly conserved genes.

Morphable materials: Researchers coax nanoparticles to reconfigure themselves      (via sciencedaily.com)     Original source 

A view into how nanoscale building blocks can rearrange into different organized structures on command is now possible with an approach that combines an electron microscope, a small sample holder with microscopic channels, and computer simulations, according to a new study.

Spider exploits firefly's flashing signals to lure more prey      (via sciencedaily.com)     Original source 

Fireflies rely on flashing signals to communicate to other fireflies using light-emitting lanterns on their abdomens. In fireflies of the species Abscondita terminalis, males make multi-pulse flashes with two lanterns to attract females, while females make single-pulse flashes with their one lantern to attract males. Now researchers have evidence that an orb-weaving spider (Araneus ventricosus) manipulates the flashing signals of male fireflies ensnared in its web such that they mimic the typical flashes of a female firefly, thereby luring other males to serve as their next meal.

Hailstone library to improve extreme weather forecasting      (via sciencedaily.com)     Original source 

Researchers are measuring and scanning samples for a global 'hailstone library'. Storm simulations using 3-D modelling of real hailstones -- in all sorts of weird shapes from oblong to flat discs or with spikes coming out -- show it behaves differently than spherical hail shapes. Data from the hail library could lead to more accurate storm forecasts.

Rethinking the dodo      (via sciencedaily.com)     Original source 

Researchers are setting out to challenge our misconceptions about the Dodo, one of the most well-known but poorly understood species of bird. Researchers have undertaken the most comprehensive review of the taxonomy of the Dodo and its closest relative, the Rodriguez Island Solitaire.

New research shows unprecedented atmospheric changes during May's geomagnetic superstorm      (via sciencedaily.com)     Original source 

On May 11, a gorgeous aurora surprised stargazers across the southern United States. That same weekend, a tractor guided by GPS missed its mark. What do the visibility of the northern lights have in common with compromised farming equipment in the Midwest? A uniquely powerful geomagnetic storm, according to new research.

Blind cavefish have extraordinary taste buds      (via sciencedaily.com)     Original source 

A biologist studies blind cavefish, a species of fish that dwell in cave ponds in Mexico. He looked at the timeline for when the cavefish develop additional taste buds on the head and chin, finding the taste bud expansion starts at five months and continues into adulthood.
