About eight percent of red giants are covered by sunspot-like, dark areas; these stars rotate faster than others of their kind. Starspots are more common among red giant stars than previously thought. Astronomers report that approximately eight percent of red giants exhibit such spots. Although red giants are generally regarded as slowly rotating stars, those with starspots are apparently an exception. The new publication offers a comprehensive analysis of the reasons for their short rotation periods.

Among the Sun’s most striking features are its sunspots, relatively darker areas compared to the rest of the surface, some of which are visible from Earth even without magnification...

Scientists have developed a new cancer vaccine with the potential to activate the body’s immune system to fight a range of cancers, including leukaemia, breast cancer, lung cancer and pancreatic cancers.

Scientists are ready to trial a new cancer vaccine in humans following the successful outcome of their preclinical studies.

The new vaccine was developed by a Mater Research team based at The Translational Research Institute in collaboration with The University of Queensland.

Lead Researcher Associate Professor Kristen Radford says the vaccine has the potential to treat a variety of blood cancers ...

Scientists are a step closer to developing a fast and cost effective camera that utilises terahertz radiation, potentially opening the opportunity for them to be used in non-invasive security and medical screening.

A research team led by Professor Emma Pickwell-Macpherson from the University of Warwick Department of Physics and involving Rayko Ivanov Stantchev and scientists from the Department of Electronic Engineering at The Chinese University of Hong Kong has reached a crucial milestone towards developing single-pixel terahertz imaging technology for use in biomedical and industrial applications.

Their single-pixel terahertz camera reached 100 times faster acquisition than the previous state-of-the-art without a...

Scientists at Harvard University and the Black Hole Initiative (BHI) have developed a new method to find black holes in the outer solar system, and along with it, determine once-and-for-all the true nature of the hypothesized Planet Nine. The paper, accepted to The Astrophysical Journal Letters, highlights the ability of the future Legacy Survey of Space and Time (LSST) mission to observe accretion flares, the presence of which could prove or rule out Planet Nine as a black hole.
