Although closely related to the notorious carnivore Tyrannosaurus rex, a new lineage of dinosaur discovered in Chile is proving to be an evolutionary jigsaw puzzle, as it preferred to graze upon plants.

Palaeontologists are referring to Chilesaurus diegosuarezi as a 'platypus' dinosaur because of its extremely bizarre combination of characters that include a proportionally small skull and feet more akin to primitive long-neck dinosaurs.

Hot vents on the seabed could have spontaneously produced the organic molecules necessary for life, according to new research by UCL chemists. The study shows how the surfaces of mineral particles inside hydrothermal vents have similar chemical properties to enzymes, the biological molecules that govern chemical reactions in living organisms. This means that vents are able to create simple carbon-based molecules, such as methanol and formic acid, out of the dissolved CO2 in the water.

Researchers from Queen Mary University of London (QMUL) and Royal Holloway, University of London (RHUL), gave bumblebees the option to choose between a sugar solution with nicotine in it and one without. Those bees infected with the Crithidia bombi parasite were more likely to go for the nicotine-laced nectar than those that weren't infected.

Researchers have performed the first human-based study to identify calcium channels in cerebral arteries and determine the distinct role each channel plays in helping control blood flow to the brain. The study appears in the May issue of The Journal of General Physiology.

A protein that normally fosters tissue repair instead acts to inhibit healing when sugar levels are high, according to a study in The Journal of Cell Biology. The role reversal helps explain why wounds heal slowly in people with diabetes.

UK scientists may have uncovered a natural way of avoiding the use of pesticides and help save plants from attack by recreating a natural insect repellent.

Scientists from Cardiff University and Rothamsted Research have, for the first time, created tiny molecules which mirror a natural occurring smell known to repel insects.

The scientists were able to make similar smelling insect repellent molecules, by providing the enzyme, ((S)-germacrene D synthase), which creates the smell, with alternative substrate molecules.

The first three eggs of the rare ‘Akeke‘e have hatched under the auspices of San Diego Zoo Global conservation biologists. The newly hatched chicks represent hope for the survival of a small Hawaiian honeycreeper.

Eggs from two species of rare Hawaiian honeycreeper birds, the ‘Akikiki and ‘Akeke‘e, were collected from native habitat earlier this month as part of an effort to preserve these two bird species from extinction.

Metformin, a medication commonly taken for Type II diabetes, which is being found in freshwater systems worldwide, has been shown to cause intersex in fish -male fish that produce eggs.

A study by Rebecca Klaper at the University of Wisconsin-Milwaukee determined exposure to the diabetes medicine metformin causes physical changes in male fish exposed to doses similar to the amount in wastewater effluent.

Researchers have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation.

Dropping off a child at kindergarten for the first time can be one of the most memorable yet terrifying experiences of parenthood. Among the many concerns parents face is the worry whether your child will make friends - a key factor, research shows, in reducing anxiety, depression and the likelihood of being bullied.

A team of Belgian philosophers and plant biotechnologists have turned to cognitive science to explain why opposition to genetically modified organisms (GMOs) has become so widespread, despite positive contributions GM crops have made to sustainable agriculture. In a paper published April 10 in Trends in Plant Science, they argue that the human mind is highly susceptible to the negative and often emotional representations put out by certain environmental groups and other opponents of GMOs.

Thinking "time is money" can be a barrier for people to act in environmentally friendly ways, even for tasks like recycling that take mere seconds, according to UBC research.

Gigantic volumes of hot material rising from the deep earth's mantle to the base of the lithosphere have shaped the face of our planet. Provided they have a sufficient volume, they can lead to break-up of continents or cause mass extinction events in certain periods of the Earth's history. So far it was assumed that because of their high temperatures those bodies - called mantle plumes - ascend directly from the bottom of the earth's mantle to the lithosphere.

A very small and rare species of shark is swimming its way through scientific literature. But don't worry, the chances of this inches-long vertebrate biting through your swimsuit is extremely slim, because if you ever spotted one you'd be the third person to ever do so.

In an effort that reaches back to the 19th-century laboratories of Europe, a discovery by University of Georgia chemistry researchers establishes new research possibilities for silicon chemistry and the semiconductor industry.

The study, published April 20 in the journal Nature Chemistry, gives details on the first time chemists have been able to trap molecular species of silicon oxides.
