Small tweaks in component ratios generate electronically different layers from the same material to create transparent transistors.

Worldwide demand is growing for transparent conducting oxides for use in , , smart windows and semiconductor-based consumer electronics. KAUST researchers have engineered a zinc-oxide-based that displays tunable electronic properties depending on the tweaking of a new type of dopant.

Transparent electronics rely on indium tin oxide, a transparent and electrically conductive material that has an exorbitant cost due to the scarcity of indium. Zinc-oxide-based materials, such as hafnium-doped zinc-oxide materials, are expected to offer affordable, green and abundant alternatives to . However, hafnium-doped zinc-oxide materials typically require high deposition temperatures and display inadequate performance for real-life device applications.

No matter how abundant or renewable, solar power has a thorn in its side. There is still no cheap and efficient long-term storage for the energy that it generates.

The solar industry has been snagged on this branch for a while, but in the past year alone, a series of four papers has ushered in an intriguing new solution.

Scientists in Sweden have developed a specialised fluid, called a solar thermal fuel, that can store energy from the sun for well over a decade.

Solar rays are a plentiful, clean source of energy that is becoming increasingly important as the world works to shift away from power sources that contribute to global warming. But current methods of harvesting solar charges are expensive and inefficient—with a theoretical efficiency limit of 33 percent. New nanomaterials developed by researchers at the Advanced Science Research Center (ASRC) at The Graduate Center of The City University of New York (CUNY) could provide a pathway to more efficient and potentially affordable harvesting of solar energy.

Monash researchers have unlocked a key process in all human cells that contributes to diseases like cancer and neurodegenerative diseases as well as ageing. The discovery reveals how cells efficiently get rid of cellular junk, which when it accumulates, can trigger death and the health problems associated with getting older.

Autophagy is the ‘clean-up crew’ of the cell—used by cells to break-down debris like broken proteins, bits of cell , viruses or bacteria. To capture this trash, cells use specialised membranes to trap the cargo for recycling into new parts and energy. Without efficient autophagy cells become choked by their own damaged components, which can contribute to the development of a range of diseases, including diabetes, muscular dystrophy, Parkinson’s and Alzheimer’s disease.

Dr. Michael Lazarou’s laboratory from the Monash Biomedicine Discovery Institute have today published data in Nature Communications that debunks previously held beliefs about how cells target their trash. Cells target different types of cargo by using ‘autophagy receptors’, which can bind the cargo as well as the ensnaring membranes. Until recently these autophagy receptors were thought to recruit the membranes to the cargo, but research led by Dr. Benjamin Padman from the Lazarou lab now shows that this is not the case.

MAJOR BREAKTHROUGH: A recent study affiliated with UNIST has developed a system that produces electricity and hydrogen (H2) while eliminating carbon dioxide (CO2), the main contributor of global warming. This breakthrough has been led by Professor Guntae Kim in the School of Energy and Chemical Engineering at UNIST in collaboration with Professor Jaephil Cho in the Department of Energy Engineering and Professor Meilin Liu in the School of Materials Science and Engineering at Georgia Institute of Technology.

In this work, the research team presented a hybrid Na-CO2 system that can continuously produce electrical and hydrogen through efficient CO2 conversion with stable operation for over 1,000 hours from spontaneous CO2 dissolution in aqueous solution.

“Carbon capture, utilization, and sequestration (CCUS) technologies have recently received a great deal of attention for providing a pathway in dealing with global climate change,” says Professor Kim. “The key to that technology is the easy conversion of chemically stable CO2 molecules to other materials.” He adds, “Our new system has solved this problem with CO2 dissolution mechanism.”

Saying farewell to coffee isn’t that easy. According to research about three-fifths of all our beloved coffee species are going to go extinct. This is a phenomenal amount of coffee that we risk losing.

Here’s something to think about as you sip that morning mochaccino:?Deforestation, climate change and the proliferation of pests and fungal pathogens are putting most of the world’s wild coffee species at risk of extinction.

At least 60 percent of wild coffee species are considered “threatened,” according to a study published this week in Science Advances. And fewer than half of all the wild species are safeguarded in so-called germplasm collections—banks for seed and living plants kept in protected areas as backups.

Utopistics is an emerging field in political science, dealing with the creation of an alternative social system or civilization with different values and priorities from the dominant ones today. Learn about it with this video:

Is there a viable alternative to the neoliberal economic consensus?

Is the nationalism and protectionism of Trump and similar politicians the only alternative?

Is another world possible?

Is a respected alternative even necessary for us to justify getting rid of a reigning economic or social system?

These questions are all relevant to futurism, which closely resembles utopistics in its scope and often asks similar questions.
