Komodo dragons have iron-coated teeth to rip apart their prey      (via sciencedaily.com)     Original source 

Scientists have discovered that the serrated edges of Komodo dragons' teeth are tipped with iron. The study gives new insight into how Komodo dragons keep their teeth razor-sharp and may provide clues to how dinosaurs like Tyrannosaurus rex killed and ate their prey.

Scientists assess how large dinosaurs could really get      (via sciencedaily.com)     Original source 

A study looks at the maximum possible sizes of dinosaurs, using the carnivore, Tyrannosaurus rex, as an example. Using computer modelling, experts produced estimates that T. Rex might have been 70% heavier than what the fossil evidence suggests.

Whale shark tracked for record-breaking four years      (via sciencedaily.com)     Original source 

Researchers have been tracking a 26-foot endangered whale shark -- named 'Rio Lady' -- with a satellite transmitter for more than four years -- a record for whale sharks and one of the longest tracking endeavors for any species of shark.

Images of nearest 'super-Jupiter' open a new window to exoplanet research      (via sciencedaily.com)     Original source 

Using the James Webb Space Telescope (JWST), astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun. This measurement was only possible thanks to JWST's unprecedented imaging capabilities in the thermal infrared. It exemplifies the potential of finding many more such planets similar to Jupiter in mass, temperature, and orbit. Studying them will improve our knowledge of how gas giants form and evolve in time.

Eyes for Love: Searching for light and a mate in the deep, dark sea, male dragonfishes grow larger eyes than the females they seek      (via sciencedaily.com)     Original source 

The eyes of the male dragonfish grow larger for mate seeking, a sexual dimorphism that makes the dragonfish an anomaly in vertebrate evolution, researchers report.

Taco-shaped arthropod fossils gives new insights into the history of the first mandibulates      (via sciencedaily.com)     Original source 

Palaeontologists are helping resolve the evolution and ecology of Odaraia, a taco-shaped marine animal that lived during the Cambrian period. Fossils reveal Odaraia had mandibles. Palaeontologists are finally able to place it as belonging to the mandibulates, ending its long enigmatic classification among the arthropods since it was first discovered in the Burgess Shale over 100 years ago and revealing more about early evolution and diversification.

Butterflies accumulate enough static electricity to attract pollen without contact      (via sciencedaily.com)     Original source 

Butterflies and moths collect so much static electricity whilst in flight, that pollen grains from flowers can be pulled by static electricity across air gaps of several millimeters or centimeters.

Study uses Game of Thrones to advance understanding of face blindness      (via sciencedaily.com)     Original source 

Psychologists have used the hit TV series Game of Thrones to understand how the brain enables us to recognize faces. Their findings provide new insights into prosopagnosia or face blindness, a condition that impairs facial recognition.

Expiring medications could pose challenge on long space missions      (via sciencedaily.com)     Original source 

A new study shows that over half of the medicines stocked in space -- staples such as pain relievers, antibiotics, allergy medicines, and sleep aids -- would expire before astronauts could return to Earth.

Hunter-gatherers kept an 'orderly home' in the earliest known British dwelling      (via sciencedaily.com)     Original source 

Archaeological evidence from the world-famous Mesolithic site of Star Carr in North Yorkshire has shown that hunter-gatherers likely kept an orderly home by creating 'zones' for particular domestic activities.

Astrophysicists uncover supermassive blackhole/dark matter connection in solving the 'final parsec problem'      (via sciencedaily.com)     Original source 

Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of supermassive black holes (SMBHs) can merge into a single larger black hole because of previously overlooked behavior of dark matter particles, proposing a solution to the longstanding 'final parsec problem' in astronomy.

Smell of human stress affects dogs' emotions leading them to make more pessimistic choices      (via sciencedaily.com)     Original source 

Dogs experience emotional contagion from the smell of human stress, leading them to make more 'pessimistic' choices, new research finds. Researchers tested how human stress odors affect dogs' learning and emotional state.

Controlling mosquito populations through genetic breeding      (via sciencedaily.com)     Original source 

Researchers have found a new way to identify genetic targets useful for control of mosquito populations, potentially offering an alternative to insecticides. Their study focused on the genetic basis of species incompatibility. They crossed Ae. aegypti, a major global arboviral disease vector, and its sibling species, Ae. mascarensis, from the Indian Ocean. When offspring is crossed back with one parent, about 10 percent of the progeny becomes intersex and is unable to reproduce.

Chimpanzees gesture back and forth quickly like in human conversations      (via sciencedaily.com)     Original source 

When people are having a conversation, they rapidly take turns speaking and sometimes even interrupt. Now, researchers who have collected the largest ever dataset of chimpanzee 'conversations' have found that they communicate back and forth using gestures following the same rapid-fire pattern.

Life signs could survive near surfaces of Enceladus and Europa      (via sciencedaily.com)     Original source 

Europa and Enceladus, icy moons of Jupiter and Saturn respectively, have evidence of oceans beneath their crusts. A NASA experiment suggests -- if these oceans support life -- signatures of that life in the form of organic molecules (like amino acids and nucleic acids) could survive just under the surface ice despite the harsh, ionizing radiation on these worlds. If robotic landers were to go to these moons to look for life signs, they would not have to dig very deep to find amino acids that have survived being altered or destroyed by radiation.
