The most common birds nests found today had their birthplace in Australia, and these nests may be key to many of our birds' success, according to new research from Macquarie University, released today.

Analysis software uses algorithms to visualize complex learning processes
Neural networks are commonly used today to analyze complex data – for instance to find clues to illnesses in genetic information. Ultimately, though, no one knows how these networks actually work exactly. That is why Fraunhofer researchers developed software that enables them to look into these black boxes and analyze how they function. The researchers will present their software at CeBIT in Hanno

Ny PLO-formand i Hovedstaden: Jeg vil meget gerne bevare diversiteten i almen praksis
Karin Zimmer vil som ny regionalformand for de praktiserende læger i almen praksis bl.a samarbejde med regionen om at sikre lægedækning og bevare diversiteten i almen praksis.

Residents of Flint, Mich., Sue EPA over Water Crisis
The lawsuit asserts that the EPA failed to warn the community of the dangers of the toxic water or take steps to ensure that state and local authorities addressed the crisis —

Early brain changes in fragile X syndrome, study shows
A new study is giving researchers a first look at the early stages of brain development in patients with Fragile X syndrome, a disorder that causes mild to severe intellectual disability and is the most common genetic cause of autism spectrum disorder.

Researchers decode rare form of adrenal gland genetic disorder linked to gender ambiguity
A complete clinical and genetic profile of a rare inherited disorder, steroid 11-hydroxylase deficiency, which can cause genital masculinization in females, is being reported by an international group of researchers. Postnatal screening and treatment may prevent females from being raised as males.

New smartphone app looks inside objects
A new app from Fraunhofer development engineers looks directly inside objects and displays specific constituents. It has numerous uses: For instance, apples can be scanned for pesticide residues. Applications will be added successively following the Wikipedia principle.

Image: Solar array drive mechanism on microvibration unit
The smooth running of the mechanism that will align the solar wings powering Europe's latest weather satellite has been demonstrated using ESA's new microvibration unit.

Mind the gap—Rapid Burster behaviour explained
Scientists observing a curious neutron star in a binary system known as the 'Rapid Burster' may have solved a forty-year-old mystery surrounding its puzzling X-ray bursts. They discovered that its magnetic field creates a gap around the star, largely preventing it from feeding on matter from its stellar companion. Gas builds up until, under certain conditions, it hits the neutron star all at once,

Newly discovered breathing molecule vital to treating respiratory conditions
Respiratory conditions could be better targeted and treated, thanks to the discovery of the vital molecule which regulates breathing – according to research by the University of Warwick.

Space travel visionaries solve the problem of interstellar slowdown at Alpha Centauri
In April last year, billionaire Yuri Milner announced the Breakthrough Starshot Initiative. He plans to invest 100 million US dollars in the development of an ultra-light light sail that can be accelerated to 20 percent of the speed of light to reach the Alpha Centauri star system within 20 years. The problem of how to slow down this projectile once it reaches its target remains a challenge. René

6 Cosmic Catastrophes That Could Wipe Out Life on Earth
If you ask yourself what the biggest threat to human existence is you'd probably think of nuclear war, global warming or a large-scale pandemic disease. But assuming we can overcome such challenges, are we really safe?

Researchers complete first stage of experiment to study giant air showers
The first stage of a study on giant air showers has been completed at NEVOD-SHAL, a new facility created at the territory of the National Research Nuclear University MEPhI (Russia) as a part of a Russian-Italian collaboration.

Ultrahigh sensitivity graphene infrared detectors for imaging and spectroscopy
Researchers from the Graphene Flagship have developed a novel graphene-based infrared (IR) detector demonstrating record high sensitivity for thermal detection. Graphene's unique attributes pave the way for high-performance IR imaging and spectroscopy.

Astronauts' brains change shape during spaceflight
MRIs before and after space missions reveal that astronauts' brains compress and expand during spaceflight, according to a University of Michigan study.

How to improve data management in the supercomputers of the future
Researchers at Universidad Carlos III de Madrid (UC3M) are establishing new foundations for data management in the supercomputing systems of the future. In recent decades, many scientific discoveries have depended on the analysis of an enormous volume of data, which is done essentially through computational simulations performed on a large scale in supercomputers. This type of machine is used to s

Research journey to the center of the Earth
Researchers in Japan say they may be one step closer to solving a mystery at the core of the Earth. It has long been established that approximately 85 percent of the Earth's core is made of iron, while nickel makes up an additional 10 percent. Details of the final 5 percent—believed to be some amount of light elements—has, until now, eluded scientists.

Scientists show how cells communicate
Primary cilia are antenna-like structures present on the surface of most cells in the human body. The cilia are essential mediators of communication between cell types in the body. If the cilia are defective, this communication is disrupted, and the cells are unable to appropriately regulate important cellular processes, which ultimately can lead to severe diseases that may affect nearly every org
