NASA's new Transiting Exoplanet Survey Satellite (TESS) is designed to ferret out habitable exoplanets, but with hundreds of thousands of sunlike and smaller stars in its camera views, which of those stars could host planets like our own? | Continue reading
It's been over ten years since Kevin Rudd's Digital Education Revolution placed small laptops (also called Rudd-tops) into the hands of every Year 9 and up Australian student. Once the scheme was deemed unsustainable, for obvious reasons, many schools brought in a "bring your own … | Continue reading
A technique to produce eggs from ovarian tissue in the lab may offer hope for critically endangered species like the Northern White Rhino that have passed what is currently considered the point of no return. | Continue reading
Computers were once considered high-end technology, only accessible to scientists and trained professionals. But there was a seismic shift in the history of computing during the second half of the 1970s. It wasn't just that machines became much smaller and more powerful—though, o … | Continue reading
Employees who enjoy their jobs and gain meaning from their roles are more likely to share information with their colleagues, new research led by Curtin University has found. | Continue reading
"How about that package out of your sleeve? Get that?" is certainly not the most famous phrase uttered by a human while on the Moon. And the items nestled in a small packet that astronaut Buzz Aldrin had stowed in the pocket just below the shoulder of his extravehicular mobility … | Continue reading
Chemical imaging of surfaces is critical to understand the relationships between structural, chemical and functional properties in disciplines ranging across the chemical, material and biological sciences. Conventional methods of chemical analysis are typically restricted by limi … | Continue reading
Seeds remain in a dormant state, a temporary blockage of their germination, as long as environmental conditions are not ideal for germination. The depth of this dormancy, which is influenced by various factors, is inherited from their mother, as researchers from the University of … | Continue reading
Climate change has always left its footprint on land and in the seas where bivalves such as mussels, scallops, oysters have lived for millions of years. Their limited mobility has been to their disadvantage resulting in most of them dying in the on-site whenever major unpleasant … | Continue reading
Tissue engineering is a medical solution that uses living cells to repair or replace structural tissue, such as blood vessels, bone, cartilage, etc. Polymeric hydrogels, in both solid and liquid forms, are used as a delivery system for living cells, acting as a protective layer t … | Continue reading
Anyons form the basis for topological quantum computation and error correction, where the topological aspect of anyonic braiding is one of the important features that gives rise to fault tolerance. More qubits to control will assist researchers to explore further. | Continue reading
Crop models are parameterization schemes that simulate the processes of crop development and production. Their inclusion in climate models can promote the simulation ability of climate models, according to Dr. Jing Zou at the Institute of Oceanographic Instrumentation, Qilu Unive … | Continue reading
A team of researchers affiliated with several institutions in Israel has found evidence that suggests rapid climate change might have been a factor in the fall of part of the Byzantine Empire. In their paper published in Proceedings of the National Academy of Sciences, the group … | Continue reading
Sparks are a fascinating phenomenon well-known from campfires, flint stones and electric sparklers and other pyrotechnic articles. Looking at sparks more closely reveals the limited colors in which they appear. Dark red-orange sparks are known from charcoal, iron powder leads to … | Continue reading
MicroRNAs (miRNAs) are short noncoding regulatory RNAs that can repress gene expression post-transcriptionally and are therefore increasingly used as biomarkers of disease. Detecting miRNAs can be arduous and expensive as they require amplification, labelling and radioactive prob … | Continue reading
RuBisCO plays a key role in photosynthesis and is one of the most abundant enzymes in the world. A Japanese research team has revealed how charge distribution on RuBisCO's active sites is linked to the enzyme's ability to recognize carbon dioxide. This discovery can potentially b … | Continue reading
Silver, gold and copper nanowires are leading contenders for next-generation nanoscale devices, however greater understanding of how they work and improved production methods are needed before they can be widely used, explains a recent review in the journal Science and Technology … | Continue reading
Two astronomers from the Max Planck Institute for Astronomy and from the University of Jena have found an elegant new method to measure the energy of simple chemical reactions, under similar conditions as those encountered by atoms and molecules in the early solar system. Their m … | Continue reading
When people think about artificial intelligence, or AI, they can be quick to jump to the all-too-common sci-fi depiction of a heartlessly rational computer willing to kill people to fulfill its programming. | Continue reading
The rapid elevation of atmospheric carbon dioxide level has led to global warming and ocean acidification. Microalgae, accounting for nearly 40 percent of global carbon dioxide fixation on Earth, are on the forefront of mankind's battle against climate change, since many of them … | Continue reading
The effects of extreme warming have been felt across the globe in recent years, especially with intensely hot summers in eastern Asia, western Europe, and North America.
