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.

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.

Researchers have developed an efficient concept to turn carbon dioxide into clean, sustainable fuels, without any unwanted by-products or waste.

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.

A chemical used in electric vehicle batteries could also give us carbon-free fuel for space flight, according to new research.

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.

Scientists have discovered the first evidence of a unique respiratory infection in the fossilized remains of a dinosaur that lived nearly 150 million years ago. Researchers examined the remains of an immature diplodocid -- a long-necked herbivorous sauropod dinosaur, like 'Brontosaurus' - dating back to the Late Jurassic Period of the Mesozoic Era. The dinosaur nicknamed 'Dolly,' discovered in southwest Montana, had evidence of an infection in the area of its neck vertebrae.

Researchers show how magnetic flux sensors can be used to monitor the operation of proton exchange membrane fuel cells that run on hydrogen. By detecting changes in current, failure states due to incorrect water levels can be identified. This work may lead to cost-effective sustainable energy generation for electric vehicles.

A new catalyst extracts hydrogen from hydrogen storage materials easily and efficiently. The process occurs at mild temperatures and under normal atmospheric conditions, without using metals or additives.

European scientists have achieved a major success on the road to energy production through fusion plasmas: They produced stable plasmas with 59 megajoules of energy output at the world's largest fusion facility, JET, in Culham near Oxford, UK.

Researchers have described the new species of titanosaur dinosaur Abditosaurus kuehnei from the remains excavated at the Orcau-1 site, in the southern Pyrenees (Catalonia, Spain). The semiarticulated 70.5-million-year-old skeleton is the most complete specimen of this herbivorous group of dinosaurs discovered so far in Europe.

For the first time ever on a global scale, using satellite imagery, scientists have quantified volumes of massive methane emissions due to fossil-fuel extraction activities and their impact on the climate. Their findings partly explain why official inventories generally underestimate the volume of these emissions. Stopping these releases, be they accidental or deliberate, would save those countries responsible billions of dollars.

A new high-temperature polymer fuel cell that operates at 80-160 degrees Celsius, with a higher-rated power density than state-of-the-art fuel cells, solves the longstanding problem of overheating, one of the most significant technical barriers to using medium-and heavy-duty fuel cells in transportation vehicles such as trucks and buses.

New research shows that fuel poverty makes people's physical and mental health worse. Researchers found that not being able to keep homes warm enough affects people's levels of life satisfaction. But they also found that it impacts people's physical health by causing higher levels of inflammation, measured by fibrinogen, a blood-based biomarker.

Dinosaurs came to flourish during the Jurassic period after a volcanic eruption roughly 201 millions years ago wiped out many marine and land animals, leaving them able to evolve and grow. Now, further details about this eruption and the mass extinction have been revealed. A group of researchers demonstrated how low temperature magma slowly heated sedimentary rocks, causing high sulfur dioxide and low carbon dioxide emissions, a process which cooled the earth.

New research has revealed how giant 50-ton sauropod dinosaurs, like Diplodocus, evolved from much smaller ancestors, like the wolf-sized Thecodontosaurus.

Scientists took a closer look at the braincase of a dinosaur from Austria. The group examined the fossil with a micro-CT and found surprising new details: it was sluggish and deaf.

The two-meter skull of an enormous new ichthyosaur species, Earth's first known giant creature, reveals how both the extinct marine reptiles and modern whales became giants.
