A study of Saturn's largest moon may offer insights for earth
Scientists studying the weather and climate of Titan, Saturn's largest moon, have reported a significant seasonal variation in its energy budget—that is the amount of solar energy absorbed by the celestial body and the thermal energy it emits.
US scores above average in reading, science, lags in math
American students may not be reading any better, but they're moving up in rankings of educational achievement worldwide because many of their peers in other countries are performing worse.
Great Barrier Reef study shows how reef copes with rapid sea-level rise
A new study into the recent history of the Great Barrier Reef has shown how it responds to rapid sea-level rise and other environmental stresses. The study, conducted at the University of Sydney's research station at One Tree Island, has upended the established model of Holocene-era reef growth.
Dramatic transition in Streptomyces life cycle explained in new discovery
Streptomyces bacteria are our primary source of antibiotics, which are produced in the transition from vegetative growth to sporulation in a complex developmental life cycle.
VTT developed an optical fiber made of cellulose
VTT researchers were able to transmit light in wood-based fibre. Optical fibre made of cellulose is best suited for sensors that benefit from the biodegradability of the material. In the future, optical cellulose fibre may allow detecting changes in the moisture level of buildings.

A surprising analysis of the composition of gas giant exoplanets and their host stars shows that there isn't a strong correlation between their compositions when it comes to elements heavier than hydrogen and helium. This finding has important implications for our understanding of the planetary formation process.

A survey of coral reef cores on the Great Barrier Reef has revealed how it has responded to recent periods of rapid sea-level rise. The study, covering the past 9000 years, has revealed a system in delicate balance.
What's driving erosion worldwide?

- 19/12/3 17:45
Researchers are reexamining the causes of soil erosion around the world -- and have found that countries themselves have a surprisingly strong influence on their soil. This country effect was previously undetected.
Eating in sync with biological clock could replace problematic diabetes treatment

A new study finds that a starch-rich breakfast consumed early in the morning coupled with a small dinner could replace insulin injections and other diabetes medications for many diabetics.
How the strep bacterium hides from the immune system
- ScienceDaily
- 19/12/3 17:45
A bacterial pathogen that causes strep throat and other illnesses cloaks itself in fragments of red blood cells to evade detection by the host immune system, according to a new study. The researchers found that Group A Streptococcus (GAS) produces a previously uncharacterized protein, named S protein, which binds to the red blood cell membrane to avoid being engulfed and destroyed by phagocytic...
2010s hottest decade in history, UN says as emissions rise again
This decade is set to be the hottest in history, the United Nations said Tuesday in an annual assessment outlining the ways in which climate change is outpacing humanity's ability to adapt to it.
Finnish rivers transport carbon to the Baltic Sea at an increasing rate
The amount of carbon transported via Finnish rivers to the Baltic Sea has risen substantially in the past few decades. This was found in a collaborative study by the University of Helsinki, Aarhus University and the Finnish Environment Institute. The researchers don't know the exact effects yet.
Love, lies and money: Study introduces, defines and measures financial infidelity
Romantic relationships are built on trust—yet when it comes to money, even faithful partners are not always honest about their spending and saving habits.
Scientist develops game to arm users against climate change 'fake news'
A George Mason University scientist is developing a mobile game that will teach users to defend themselves from 'fake news' on climate change.
Researchers map the formation of ducts connecting digestive organs in zebrafish
A specialised system of ducts transports bile and enzymes from the liver and pancreas to the intestine. In a new study, researchers from the University of Copenhagen have shown how this ductal system is formed. The new knowledge can help understanding how congenital diseases in that part of the body arise.
Meteorite-loving microorganism
Chemolithotrophic microorganisms derive their energy from inorganic sources. Research into the physiological processes of these organisms—which are grown on meteorite—provides new insights into the potential of extraterrestrial materials as a source of accessible nutrients and energy for microorganisms of the early Earth. Meteorites may have delivered a variety of essential compounds...
Bionic neurons could enable implants to restore failing brain circuits
Scientists say creation could be used to circumvent nerve damage and help paralysed people regain movementScientists have created artificial neurons that could potentially be implanted into patients to overcome paralysis, restore failing brain circuits, and even connect their minds to machines.The bionic neurons can receive electrical signals from healthy nerve cells, and process them in a natural...
Smog-eating graphene composite reduces atmospheric pollution
Graphene Flagship partners the University of Bologna, Politecnico di Milano, CNR, NEST, Italcementi HeidelbergCement Group, the Israel Institute of Technology, Eindhoven University of Technology, and the University of Cambridge have developed a graphene-titania photocatalyst that degrades up to 70% more atmospheric nitrogen oxides (NOx) than standard titania nanoparticles in tests on real...
Greta Thunberg: People underestimate 'angry kids'
Climate activist Greta Thunberg said that adults should stop making young people "angry" over global warming.
Diamonds in your devices: Powering the next generation of energy storage
Our use of battery-operated devices and appliances has been increasing steadily, bringing with it the need for safe, efficient, and high-performing power sources. To this end, a type of electrical energy storage device called the supercapacitor has recently begun to be considered as a feasible, and sometimes even better, alternative to conventional widely used energy-storage devices such as Li-ion...
Two chiral catalysts working hand in hand
Just as our left hand is not superposable to our right hand, the mirror image of certain molecules cannot be overlapped onto it, even when turned or twisted. These two mirror images are referred to by chemists as enantiomers and the molecule is said to be chiral. Chirality, which is a word derived from the ancient Greek word for hand, is important since it is present in our daily lives. For...
