Creature the size of a dust grain found hiding in California's Mono Lake      (via sciencedaily.com)     Original source 

Mono Lake is a beautiful but harsh environment, its salty and arsenic-laced water home to brine shrimp, alkali flies and little else. Scientists recently discovered an unsuspected resident, however, a microscopic creature -- a choanoflagelatte -- that forms colonies that harbor their own unique bacterial microbiomes. The creature, part of the sister group to all animals, could shed light on the evolution of animals' intimate interactions with bacteria and the rise of multicellular life.

To kill mammoths in the Ice Age, people used planted pikes, not throwing spears, researchers say      (via sciencedaily.com)     Original source 

Archeologists say new findings might help resolve the debate about Clovis points and reshape how we think about what life was like roughly 13,000 years ago. After an extensive review of writings and artwork -- and an experiment with replica Clovis point spears -- a team of archaeologists says humans may have braced the butt of their weapons against the ground in a way that would impale a charging animal. The force would have driven the spear deeper into the predator's body, unleashing a more damaging blow than even the strongest prehistoric hunters would have been capable of by throwing or jabbing megafauna.

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.

Measuring Martian winds with sound      (via sciencedaily.com)     Original source 

Martian landers have been able capture measurements of wind speeds -- some gauging the cooling rate of heated materials when winds blow over them, others using cameras to image 'tell-tales' that blow in the wind -- but there's still room for improvement. Researchers now demonstrate a novel sonic anemometric system featuring a pair of narrow-band piezoelectric transducers to measure the travel time of sound pulses through Martian air. The study accounted for variables including transducer diffraction effects and wind direction.

A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.

Cricket physics: Science behind the modern bowler technique tricking batters      (via sciencedaily.com)     Original source 

Researchers have started to unravel the mysteries of how near-horizontal bowling in cricket leads to such tough-to-hit balls. The team employed a wake survey rake device made of multiple tubes designed to capture the pressure downstream of the ball and examined the flow dynamics of cricket balls rotating up to 2,500 rpm in a wind tunnel. The group found that low-pressure zones expanded and intensified near the ball when spinning, while these zones shifted and diminished downstream. At higher spin rates, the low-pressure zone begins to change to a persistent bilobed shape. The results lend support to the theory that these newer bowling techniques tap into the Magnus effect.
