Researchers build bee robot that can twist      (via sciencedaily.com)     Original source 

A robotic bee that can fly fully in all directions has been developed. With four wings made out of carbon fiber and mylar as well as four light-weight actuators to control each wing, the Bee++ prototype is the first to fly stably in all directions. That includes the tricky twisting motion known as yaw, with the Bee++ fully achieving the six degrees of free movement that a typical flying insect displays.

NASA's Hubble hunts for intermediate-sized black hole close to home      (via sciencedaily.com)     Original source 

Astronomers have come up with what they say is some of their best evidence yet for the presence of a rare class of 'intermediate-sized' black hole that may be lurking in the heart of the closest globular star cluster to Earth, located 6,000 light-years away.

Fossils of a saber-toothed top predator reveal a scramble for dominance leading up to 'the Great Dying'      (via sciencedaily.com)     Original source 

A tiger-sized saber-toothed creature called Inostrancevia has previously only been found in Russia. But scientists have discovered its fossils in South Africa, suggesting that it migrated 7,000 miles across the supercontinent Pangaea during the world's worst mass extinction 252 million years ago. Heading to South Africa allowed it to fill a gap in a faraway ecosystem that had lost its top predators.

An X-ray look at the heart of powerful quasars      (via sciencedaily.com)     Original source 

Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective sheds light on the inner workings of quasars and how they interact with their environment.

Fossil of mosasaur with bizarre 'screwdriver teeth' found in Morocco      (via sciencedaily.com)     Original source 

Scientists have discovered a new species of mosasaur, a sea-dwelling lizard from the age of the dinosaurs, with strange, ridged teeth unlike those of any known reptile. Along with other recent finds from Africa, it suggests that mosasaurs and other marine reptiles were evolving rapidly up until 66 million years ago, when they were wiped out by an asteroid along with the dinosaurs and around 90% of all species on Earth.

Scales or feathers? It all comes down to a few genes      (via sciencedaily.com)     Original source 

Scales, spines, feathers and hair are examples of vertebrate skin appendages, which constitute a remarkably diverse group of micro-organs. Despite their natural multitude of forms, these appendages share early developmental processes at the embryonic stage. Researchers have discovered how to permanently transform the scales that normally cover the feet of chickens into feathers, by specifically modifying the expression of certain genes.

Is it an ant? Is it a plant? No, it's a spider!      (via sciencedaily.com)     Original source 

A species of tiny, colorful jumping spider employs two lines of defense to avoid being eaten: camouflaging with plants and walking like an ant. Researchers report that this combination of camouflage and movement mimicry helps the spiders evade spider-eating spiders but does not deter hungry praying mantises.

Radio signal reveals supernova origin      (via sciencedaily.com)     Original source 

Astronomers reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the exploding white dwarf star had a helium-rich companion.

Researchers discover brain circuit underlying spontaneous synchronized movement of individuals in groups      (via sciencedaily.com)     Original source 

Individual fish in schools scatter in unison when a predator is in their midst. Such precisely coordinated group movements and immobility during threats have long been observed in insects and mammals. Now, a brain pathway has been discovered that enables individual animals to rapidly coordinate a unified response, with no rehearsal required.

Astronomers observe the first radiation belt seen outside of our solar system      (via sciencedaily.com)     Original source 

Astronomers have described the first radiation belt observed outside our solar system, using a coordinated array of 39 radio dishes from Hawaii to Germany to obtain high-resolution images. The images of persistent, intense radio emissions from an ultracool dwarf reveal the presence of a cloud of high-energy electrons trapped in the object's powerful magnetic field, forming a double-lobed structure analogous to radio images of Jupiter's radiation belts.

Hidden supermassive black holes brought to life by galaxies on collision course      (via sciencedaily.com)     Original source 

Astronomers have found that supermassive black holes obscured by dust are more likely to grow and release tremendous amounts of energy when they are inside galaxies that are expected to collide with a neighbouring galaxy.

Celestial monsters at the origin of globular clusters      (via sciencedaily.com)     Original source 

Globular clusters are the most massive and oldest star clusters in the Universe. They can contain up to 1 million of them. The chemical composition of these stars, born at the same time, shows anomalies that are not found in any other population of stars. Explaining this specificity is one of the great challenges of astronomy. After having imagined that supermassive stars could be at the origin, a team believes it has discovered the first chemical trace attesting to their presence in globular proto-clusters, born about 440 million years after the Big Bang.

Hidden views of vast stellar nurseries      (via sciencedaily.com)     Original source 

Astronomers have created a vast infrared atlas of five nearby stellar nurseries by piecing together more than one million images. These large mosaics reveal young stars in the making, embedded in thick clouds of dust. Thanks to these observations, astronomers have a unique tool with which to decipher the complex puzzle of stellar birth.
