Researchers report significant seasonal variation in Titan’s energy budget – that is the amount of solar energy absorbed by the celestial body and the thermal energy it emits. The findings, reported in the journal Geophysical Research Letters, could lead to new insights about climate on Earth.

Titan is the only body in the solar system, other than Earth, with a significant atmosphere and liquid surface lakes. “By studying Titan, we can learn a lot about Earth,” said Ellen C...

‘Clever Drugs for Slimy Bugs’ in fight against Staph infections

PhD student Anthony Verderosa: Nitroxide functionalized antibiotics are promising eradication agents against Staphylococcus aureus biofilms

Bacterial biofilms that develop around golden staph infections make treatment difficult and prolonged, but researchers have shown in laboratory work that the hybrid antibiotics they have developed can destroy staph biofilms.

Eradicating deadly staph using a new breed of antibiotics has revealed promising results in research released by QUT, to help overcome one of the biggest modern medical challenges.

The bacteria attach to medical devices including catheters, artificial joints, implants and patients’ burns and wounds, establishing bacterial biofilms, a leading cause of failing antibiotic therapies and chronic infections.

Potential solution to Overheating Mobile Phones

Future magnon torque based devices such as this could allow for faster electronic gadgets that require less power and do not overheat

Researchers have developed a revolutionary way to encode computational information without using electrical current. As a global first, this could lead to faster technological devices that could efficiently use energy without overheating.

Modern computer memory encodes information by switching magnetic bits within devices. Now, a ground-breaking study conducted by researchers from the Department of Electrical and Computer Engineering at the National University of Singapore has found a new efficient way of using ‘spin waves’ to switch magnetisation at room temperature for more energy-efficient spin memory and logic devices.

Traditional electronic chips s...

Cracking 60-year-old Mystery of Sun’s Magnetic Waves

Image result for "Doppler velocities and spectral energies of observed and simulated time series."
The velocity signatures of the magnetized sunspot atmosphere observed on 14 July 2016.

A Queen’s University Belfast scientist has led an international team to the ground-breaking discovery of why the Sun’s magnetic waves strengthen and grow as they emerge from its surface, which could help to solve the mystery of how the corona of the Sun maintains its multi-million degree temperatures.

For more than 60 years observations of the Sun have shown that as the magnetic waves leave the interior of the Sun they grow in strength but until now there has been no solid observational evidence as to why this was the case.

The corona’s high temperatures have also always been a mystery. Usually the closer we are to a heat source, the warmer we feel...
