Scientists have achieved the most precise measurement to date of the mass of the W boson, one of nature's force-carrying particles. The measured value shows tension with the value expected based on the Standard Model of particle physics.

A set of dinosaur footprints in Spain has unusual features because the dinosaur that made the tracks had an injured foot, according to a new study.

Extinct for 66 million years, T. rex still inspires speculation about its anatomy, behavior and fierce physique. One conundrum: its peculiarly short forelimbs, which have relatively limited mobility. While scientists have suggested explanations, a paleontologist puts the proposals to the test and finds them wanting. He hypothesizes that the arms reduced in size to limit damage, possibly fatal, when a pack of T. rexes descended on a carcass with their bone-crunching teeth.

Prehistoric mammals bulked up, rather than develop bigger brains, to boost their survival chances once dinosaurs had become extinct, research suggests.

Scientists have found a new way to 'see' inside the simplest atomic nuclei to better understand the 'glue' that holds the building blocks of matter together. The results come from collisions of photons (particles of light) with deuterons, the simplest atomic nuclei (made of just one proton bound to one neutron). The photons act somewhat like an x-ray beam to provide the first glimpse of how particles called gluons are arranged within the deuteron.

Spinosaurus is the largest predatory dinosaur known -- over two metres longer than the longest Tyrannosaurus rex -- but the way it hunted has been a subject of debate for decades. In a new paper, palaeontologists have taken a different approach to decipher the lifestyle of long-extinct creatures: examining the density of their bones.

A new atomic nucleus 149-Lutetium, consisting of 71 protons and 78 neutrons, has been synthesized.

New research has revealed that soil erosion and wildfires contributed to a mass extinction event 201 million years ago that ended the Triassic era and paved the way for the rise of dinosaurs in the Jurassic period.

Seismic and acoustic data recorded 50 meters away from a research nuclear reactor could predict whether the reactor was in an on or off state with 98% accuracy, according to a new study.

Scientists describe the find of a new softshell turtle from the end of the Cretaceous Period.

Relatively small, but fearsome-looking stegosaur measured about 2.8 meters (9 feet) from nose to tail -- but scientists can't tell whether the remains are those of an adult or juvenile.

A physics professor has developed an innovative activity that poses the question: Is Usain Bolt faster than a 900-pound dinosaur?

Scientists have mapped 300 years of research on the prehistoric marine reptiles known as ichthyosaurs. Using a uniquely well-preserved fossil, the team has also created the scientifically most up-to-date reconstruction of an ichthyosaur currently available.

Do two promising structural materials corrode at very high temperatures when in contact with 'liquid metal fuel breeders' in fusion reactors? Researchers now have the answer. This high-temperature compatibility of reactor structural materials with the liquid breeder -- a lining around the reactor core that absorbs and traps the high energy neutrons produced in the plasma inside the reactor -- is key to the success of a fusion reactor design.

To harness the forces that power the Sun, researchers heat fuel to such a high temperature that atoms melt into electrons and nuclei to form a hot, gaseous soup called plasma. The plasma can rip through any material on Earth, so it must be confined by magnetic fields -- but it can only be controlled for short periods. Now, in a first step to prolonged control, researchers have discovered that the underlying mechanism mirrors the unlikely biological predator-prey model.

A new analysis of Tyrannosaurus skeletal remains reveals physical differences in the femur, other bones and dental structures across specimens that could suggest Tyrannosaurus rex specimens need to be re-categorized into three distinct groups or species, reports a new study.

Scientists developed a neural network deep learning technique to extract hidden turbulent motion information from observations of the Sun. Tests on three different sets of simulation data showed that it is possible to infer the horizontal motion from data for the temperature and vertical motion. This technique will benefit solar astronomy and other fields such as plasma physics, fusion science, and fluid dynamics.

The asteroid which killed nearly all of the dinosaurs struck Earth during springtime. This conclusion was drawn by an international team of researchers after having examined thin sections, high-resolution synchrotron X-ray scans, and carbon isotope records of the bones of fishes that died less than 60 minutes after the asteroid impacted.

Engineers are working to develop a new, economically viable and safe source of low carbon electricity through nuclear fusion.

Two new species of fossil birds that lived alongside the dinosaurs have ben discovered near the Great Wall of China. One of the new species had a sensitive, movable bony appendage at the tip of its lower jaw that it might have used to find food.
