Telescopes team up to study giant galaxy

 

Astronomers have used two Australian radio telescopes and several optical telescopes to study complex mechanisms that are fuelling jets of material blasting away from a black hole 55 million times more massive than the Sun.

 

Epigenetic aging linked to bipolar disorder

 

Bipolar disorder may involve accelerated epigenetic aging, which could explain why persons with the disorder are more likely to have -- and die from -- age-related diseases, according to researchers.

 

Cancer-protecting enzyme is 'also promoting its growth'

 

The NEIL3 enzyme has long been known to repair ‘day-to-day’ oxidative damage to DNA that is implicated in diseases of ageing, including dementia and cancer.

 

Night-flyers or day-trippers? Study sheds light on when moths, butterflies are active

 

Butterflies fly during the day while moths travel at night - or so you might think. In reality, their behavior is much more complicated. A new study offers the first comprehensive overview of the surprisingly complex question of when butterflies and moths are active.

 

How fires are changing the tundra’s face

 

Climate change takes a heavy toll on the tundra, increasing the probability of extreme droughts. As a result, the frequency of fires in forests, bogs and even wetlands continues to rise. In addition, the northern areas of the tundra have also become more accessible and negatively impacted by human activities in recent years.

 

Hubble's celestial snow globe

 

It's beginning to look a lot like the holiday season in this Hubble Space Telescope image of a blizzard of stars, which resembles a swirling snowstorm in a snow globe. The stars are residents of the globular star cluster Messier 79 (also known as M79 or NGC 1904), located 41,000 light-years from Earth, in the constellation Lepus.

 

Immune diseases inflict identical twins differently

 

A new study reports which epigenetic factors in certain chromosomes that make one twin more at risk for autoimmune thyroid diseases.

 

Engineers create artificial graphene in a nanofabricated semiconductor structure

 

Experts at manipulating matter at the nanoscale have made an important breakthrough in physics and materials science. They have engineered "artificial graphene" by recreating, for the first time, the electronic structure of graphene in a semiconductor device.

 

New instrument identifies unexploded artillery shells

 

Society faces threats through the malicious use of chemical, biological, radiological, nuclear and/or explosive (CBRNE) materials. The detection of illicit trafficking or other criminal acts, as well as many security and safety applications, call for novel material analysis techniques and instruments. These detection systems should be non-destructive but still be able to detect and identify the threat objects, even from inside a shielding or masking enclosure. Active interrogation methods that use penetrative particle beams can reveal the presence of CBRNE materials.

 

Shrinking wilderness ignored at our peril

 

Maps of the world's most important wilderness areas are now freely available online.
