A new record for a trapped field in a superconductor, beating a record that has stood for more than a decade, could herald the arrival of materials in a broad range of fields. Researchers managed to 'trap' a magnetic field with a strength of 17.6 Tesla -- roughly 100 times stronger than the field generated by a typical fridge magnet -- in a high temperature gadolinium barium copper oxide (GdBaCuO) superconductor, beating the previous record by 0.4 Tesla.

Researchers have detected the smallest force ever measured -- approximately 42 yoctonewtons -- using a unique optical trapping system that provides ultracold atoms. A yoctonewton is one septillionth of a newton.

Scientists have found how the electric fish's jolt evolved. Biologists identified the regulatory molecules involved in the genetic and developmental pathways that electric fish have used to convert a simple muscle into an organ capable of generating a potent electrical field.

Signals from the immune system that help repel a common parasite inadvertently can cause a dormant viral infection to become active again, a new study shows. Further research is necessary to understand the clinical significance of the finding, but researchers said the study helps illustrate how complex interactions between infectious agents and the immune system have the potential to affect illness.

While preferring silence to music from the West, chimpanzees apparently like to listen to the different rhythms of music from Africa and India, according to new research published by the American Psychological Association.

Space may appear empty -- a soundless vacuum, but it's not an absolute void. It flows with electric activity that is not visible to our eyes. NASA is developing plans to send humans to an asteroid, and wants to know more about the electrical environment explorers will encounter there.

The hunt for dark matter has taken another step forward thanks to new supercomputer simulations showing the evolution of our 'local Universe' from the Big Bang to the present day. Physicists say their simulations could improve understanding of dark matter, a mysterious substance believed to make up 85 per cent of the mass of the Universe.

Patients with persistent ringing in the ears -- a condition known as tinnitus -- process emotions differently in the brain from those with normal hearing, researchers report. Tinnitus afflicts 50 million people in the United States, and causes those with the condition to hear noises that aren't really there. These phantom sounds are not speech, but rather whooshing noises, train whistles, cricket noises or whines. Their severity often varies day to day.

Adults who watch TV three hours or more a day may double their risk of premature death from any cause. Researchers suggest adults should consider getting regular exercise, avoiding long sedentary periods and reducing TV viewing to one to two hours a day.

Consuming a plant-based diet results in a more sustainable environment and reduces greenhouse gas emissions, while improving longevity, according to new research. Based on findings that identified food systems as a significant contributor to global warming, the study focuses on the dietary patterns of vegetarians, semi-vegetarians and non-vegetarians to quantify and compare greenhouse gas emissions, as well as assess total mortality.

Scientists have developed a rechargeable battery that is all organic and could be scaled up easily for use in power plants where it can make the energy grid more resilient and efficient by creating a large-scale means to store energy for use as needed. The batteries could pave the way for renewable energy sources to make up a greater share of the nation's energy generation.

A fungus living in the soils of Nova Scotia could offer new hope in the pressing battle against drug-resistant germs that kill tens of thousands of people every year, including one considered a serious global threat. Seeking an answer to the riddle of resistance in the natural environment is a far more promising approach than trying to discover new antibiotics, a challenge which has perplexed scientists for decades. No new classes of antibiotics have been discovered since the late 1980s, leaving physicians with very few tools to fight life-threatening infections.

A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some 4-6 meters.

Women who are able to naturally have children later in life tend to live longer and the genetic variants that allow them to do so might also facilitate exceptionally long life spans, according to a new study.
