Some youth football drills riskier than others

Some youth football drills riskier than others

Nearly three quarters of the football players in the U.S. are less than 14 years old. But amid growing concern about concussion risk in football, the majority of the head-impact research has focused on college and professional players.

Coral conservation efforts aided by computer simulations

Coral conservation efforts aided by computer simulations

Contrary to a prevailing theory, coral larvae could not survive the five-thousand-kilometer trip across the Pacific Ocean to replenish endangered corals in the eastern Pacific, according to new research. Researchers used a supercomputer to simulate billions of coral larvae traveling on ocean currents over a 14.5-year period.

Medical scientists discover potent method for improving drug-free fertility treatment

Medical scientists discover potent method for improving drug-free fertility treatment

For those facing infertility, IVF has long been the established option to have a baby. Now Australian and Belgian medical scientists have discovered how to improve a woman's chances of becoming pregnant using a less invasive and cheaper alternative.

The innovation, which has already undergone pre-clinical testing, uses growth factors to enhance an existing fertility treatment known as in-vitro maturation (IVM). The result is improved egg quality and a 50% increase in embryos, with the use of minimal drugs.

Reef castaways: Can coral make it across Darwin's 'impassable' barrier?

Reef castaways: Can coral make it across Darwin's 'impassable' barrier?

An international team of researchers have shown that vulnerable coral populations in the eastern tropical Pacific have been completely isolated from the rest of the Pacific Ocean for at least the past two decades.

Ocean currents can change speed and even direction depending on the season or climatic events like El Nino.

The new study led by University of Bristol researchers has used a state-of-the-art computer model to trace the journeys of coral larvae transported at the whim of these currents.

Specialized test detects bacterial infections in youngest infants with fever

Physicians from Children's Hospital of Michigan, UC Davis Medical Center and Nationwide Children's Hospital, in collaboration with 19 other pediatric emergency departments around the country, have established a "proof of principle" for measuring patterns of ribonucleic acid (RNA) expression in the bloodstream that can enable clinicians to distinguish bacterial infections from other causes of fever

Tech issues cause most drone accidents: Research

World-first research has found technical problems rather than operator errors are behind the majority of drone accidents, leading to a call for further safeguards for the industry.

Researchers Dr Graham Wild and Dr Glenn Baxter from RMIT University's School of Engineering, along with John Murray from Edith Cowan University, completed the first examination of more than 150 reported civil incidents around the world involving drones, or Remotely Piloted Aircraft Systems (RPAS).

Potential new test to detect serious bacterial infections including meningitis and sepsis

Scientists have identified two genes that are switched on only when a child is suffering from a bacterial infection. This could allow doctors to quickly distinguish between a viral or bacterial illness, and identify early cases of potentially deadly infections.

The international team of scientists, led by researchers at Imperial College London, hope to now use the findings to develop a rapid test for use in hospitals and doctors' surgeries.

New study provides important insight into how tumors metastasize

Research has shown that the growth of cancerous tumours is affected by transforming growth factor (TGFβ) in the body's cells; TGFβ both suppresses and stimulates tumour development. But it has not been understood how this happens. A new study being published in the journal Science Signaling reveals important details behind this process.

Chemicals banned decades ago linked to increased autism risk today

Chemicals used in certain pesticides and as insulating material banned in the 1970s may still be haunting us, according to new research that suggests links between higher levels of exposure during pregnancy and significantly increased odds of autism spectrum disorder in children.

Evidence of changes to children's brain rhythms following 'brain training'

New research questions the strong claims that have been made about the benefits of 'brain training' - enhanced mental skills, a boost to education, improved clinical outcomes and sharper everyday functioning. This new study found evidence that 'brain training' changed brain signalling but no indication of other benefits.
