New research shows that large dinosaur predators evolved different shapes of eye sockets to better deal with high bite forces.According to new research, large dinosaur predators, such as Tyrannosaurus rex, evolved different shapes of eye sockets to better deal with high bite forces.While in many animals, including most dinosaurs, the eye socket is just a circular hole in the skull housing the eyeball, this is very different in large carnivores.A new study reveals how the unusual elliptical, or oval eye sockets found in…

OnePlus' upcoming budget-friendly smartwatch supposedly called the Nord Watch, will likely come in five variants. Images depicting the different designs were shared by 91mobiles. The leak suggests that the watch will arrive in two flavors - rectangular and circular. The rectangular-shaped option will offer two variants while the circular will be in three options. The renders depict a circular watch with two buttons on the right side and a big bezel around the display along with another two-button variant without the…

Ask astronomers about dark matter and one of the things they talk about is that this invisible, mysterious 'stuff' permeates the universe. In particular, it exists in halos surrounding most galaxies.  The mass of the halo exerts a strong gravitational influence on the galaxy itself, as well as on others in the neighborhood. That's pretty much the standard view of dark matter and its influence on galaxies.However, there are problems with the idea of those halos. Apparently, some oddly shaped dwarf galaxies exist that look…

The original triangle panels are all white when not displaying any of their 16 million colors; the new panels are all black when dormant. Nanoleaf says the black light panels, which it is only making a thousand…

More than 50 years ago Polish-American mathematician Mark Kac popularized a zany but mathematically deep question in his 1966 paper “Can One Hear the Shape of a Drum?” In other words, if you hear someone beat a drum, and you know the frequencies of the sounds it makes, can you work backward to figure out the shape of the drum that created those sounds? Or can more than one drum shape create the exact same set of frequencies? Kac wasn’t the first person to pose this or related questions, but he garnered considerable…

It says something about Spiritualized’s latest album, Everything Was Beautiful, that even with nine musicians onstage, their live incarnation very much performs a bare-bones version of its contents. Frontman Jason Pierce more-or-less set out his musical stall in the late 80s, while in his previous band Spacemen 3 – its pitch is in an area bound on one side by garage rock and droning psychedelia and on the other by gospel and blues – and has essentially spent the intervening 35 years either augmenting it or stripping it…

An example of visual data augmentation techniques used in machine learning, which captures the main principle of variability effects: exposure to variation along non-discriminative dimensions (i.e., by rotating, changing the color, or partially masking the target image) improves the neural networks' ability to generalize (in this case - to identify a fox), but at the cost of slowing down initial learning. Humans show a similar effect: more variable…

Scientists have located an area in the mouse genome where genetic variation is associated with differences in the mutation rate between individuals.The finding supports theory that genetic differences between individuals and species can affect the acquisition of mutations.Every organism is born with a few mutations in its genome that differ genetically from both of its parents. Such changes in an individual’s genetic code create the diversity that allows nature to select advantageous traits that drive the evolution of a…
