Mapping a large coastal glacier in Alaska revealed that its bulk sits below sea level and is undercut by channels, making it vulnerable to accelerated melting in an already deteriorating coastal habitat.
Volcanoes on Venus erupt every few months like Hawaii, study suggests
Scientists found evidence of active volcanoes on Venus by using new technology to examine old images of our next-door...
Markings on the leg and butt bones of early riders indicate people started riding horses 5,000 years ago
This is the first time scientists used human skeletons to provide insight about the origins of horse riding. Horseback riding allowed people to carry more and travel farther than ever...
NASA instrument bound for Titan could reveal chemistry leading to life
A new NASA mission to Saturn's giant moon, Titan, is due to launch in 2027. When it arrives in the mid-2030s, it will begin a journey of discovery that could bring about a new understanding of the development of life in the universe. This mission, called Dragonfly, will carry an instrument called the Dragonfly Mass Spectrometer (DraMS), designed to help scientists hone in on the chemistry at work...
Qubits put new spin on magnetism: Boosting applications of quantum computers

- 23/3/17 19:51
Research using a quantum computer as the physical platform for quantum experiments has found a way to design and characterize tailor-made magnetic objects using quantum bits, or qubits. That opens up a new approach to develop new materials and robust quantum computing.
Disproportionate percentage of females with unexplained infertility have gene variants known to cause heart problems, cancer
- ScienceDaily
- 23/3/17 19:50
About 17% of women with unexplained infertility also have gene variants known to cause disease, from common conditions like heart disease to rare problems like ALS, researchers report.
How TKI cancer drugs cause inflammatory side effects
- ScienceDaily
- 23/3/17 19:50
Tyrosine kinase inhibitors (TKI) are employed to attack specific types of cancer cells. The downside to using TKs is that they can cause serious inflammation. A team of researchers has discovered the underlying mechanism that causes this inflammation.
Stalactites and stalagmites in the battery?
- ScienceDaily
- 23/3/17 19:50
They are considered the 'Holy Grail' of battery research: so-called 'solid-state batteries'. They no longer have a liquid core, as is the case with today's batteries, but consist of a solid material. This leads to several advantages: Among other things, these batteries are more difficult to ignite and can also be manufactured on a miniature scale. Scientists have now turned their attention to the...

Noise from human activities is harming ocean invertebrates and ecosystems, new research shows.
An elegant new orchid hiding in plain sight
- ScienceDaily
- 23/3/17 19:50
It is extremely rare for a new plant species to be discovered in Japan, a nation where flora has been extensively studied and documented. Nevertheless, botanists recently uncovered a stunning new species of orchid whose rosy pink petals bear a striking resemblance to glasswork. Interestingly, it can be found in familiar environments such as lawns and parks, and even in private gardens and on...
Better simulations of neutron scattering

Mountain forests are being lost at an accelerating rate, putting biodiversity at risk
- ScienceDaily
- 23/3/17 19:50
More than 85% of the world's bird, mammal, and amphibian species live in mountains, particularly in forest habitats, but researchers report that these forests are disappearing at an accelerating rate. Globally, we have lost 78.1 million hectares (7.1%) of mountain forest since 2000 -- an area larger than the size of Texas. Much of the loss occurred in tropical biodiversity hotspots, putting...
Another crystalline layer on crystal surface as a precursor of crystal-to-crystal transition
- ScienceDaily
- 23/3/17 19:50
Ice surfaces have a thin layer of water below its melting temperature of 0 degrees Celsius. Such premelting phenomenon is important for skating and snowflake growth. Similarly, liquid often crystallizes into a thin layer of crystal on a flat substrate before reaching its freezing temperature, i.e. prefreezing. The thickness of the surface layer usually increases and diverges as approaching the...
