How to protect native, endangered birds from solar installations in Hawaiʻi

Best management practices (BMPs) for solar installations to protect Hawaiʻi's native and endangered birds have been released by the University of Hawaiʻi Pacific Cooperative Studies Unit. The new technical report synthesizes current literature on the threats posed by industrial-scale solar installations to birds, identifies the species most at risk from solar infrastructure, lists the locations...

Researchers develop a method that gives enzymes the ability to catalyze new-to-nature reactions

Enzymes are biology's catalytic workhorses, binding molecules together, splitting them apart and reconfiguring them in processes vital to everything from digestion to breathing. Their availability, efficiency and specificity have long made them popular for reactions outside biological systems as well, including those involved in food preservation, detergents and disease diagnostics.

Magnetic surprise revealed in 'magic-angle' graphene

When two sheets of the carbon nanomaterial graphene are stacked together at a particular angle with respect to each other, it gives rise to some fascinating physics. For instance, when this so-called "magic-angle graphene" is cooled to near absolute zero, it suddenly becomes a superconductor, meaning it conducts electricity with zero resistance.

Vaccines for animals, based on viruses that spread on their own, are being developed in Europe and the U.S.

Since the first lab-modified virus capable of replication was generated in 1974, an evidence-based consensus has emerged that many changes introduced into viral genomes are likely to prove unstable if released into the environment. On this basis, many virologists would question the release of genetically modified viruses that retain the capacity to spread between individual vertebrate hosts....

Does checking your credit score help or hurt?

January is filled with resolutions to start the new year off right, from exercise and diet to financial health. One area that may often be overlooked is checking your credit score, and according to new research, there may be a reason for that.

Mechanism that helps immune cells to invade tissues

To fight infections and heal injuries, immune cells need to enter tissue. They also need to invade tumors to fight them from within. Scientists have now discovered how immune cells protect their sensitive insides as they squeeze between tissue cells. The team lays the foundation for identifying new targets in cancer treatment.

California mice eat monarch butterflies

At the largest winter monarch aggregation in central Mexico, scientists have observed that rodents attack monarchs that fall to the ground. Biologists have now discovered that the western harvest mouse also eats grounded monarchs. Documenting this new feeding behavior is a reminder of little we know about the interactions that may be lost as insect populations decline.

Novel way to perform ‘general inverse design’ with high accuracy

'Inverse design' is a design approach that reverses the traditional design process and enables the designer to discover and create materials that possess a user-defined set of properties. Researchers demonstrate a nascent machine learning-based solution that uses an algorithm to identify any material that exhibits specific properties or characteristics. Termed 'general inverse design,' the novel...

Microbes produce oxygen in the dark

It is common knowledge that there would be no oxygen on Earth were it not for sunlight; the key component in photosynthesis. Now researchers have made the surprising discovery that oxygen is also produced without sunlight, possibly deep below the ocean surface.

Mass production of revolutionary computer memory moves closer with ULTRARAM™ on silicon wafers for the first time

A pioneering type of patented computer memory known as ULTRARAM™ has been demonstrated on silicon wafers in what is a major step towards its large-scale manufacture. ULTRARAM™ is novel type of memory with extraordinary properties. It combines the non-volatility of a data storage memory, like flash, with the speed, energy-efficiency and endurance of a working memory, like DRAM. To do this it...

First Covid wave raised UK adult risk of death by 40%, study finds

Level increased regardless of health but virus ‘picks on’ those already at risk of illness or deathBritain’s first wave of coronavirus raised the risk of death by more than 40% for most adults regardless of their underlying health and other factors, research suggests.Scientists examined medical records for nearly 10 million people aged 40 and over and found that, whatever a person’s risk...

Microbes produce oxygen in the dark

There is more going on in the deep, dark ocean waters than you may think: Uncountable numbers of invisible microorganisms go about their daily lives in the water columns, and now researchers have discovered that some of them produce oxygen in an unexpected way.

Researchers discover a mechanism that helps immune cells to invade tissues

To fight infections and heal injuries, immune cells need to enter tissue. They also need to invade tumors to fight them from within. Scientists from the Siekhaus group at the Institute of Science and Technology (IST) Austria now discovered how immune cells protect their sensitive insides as they squeeze between tissue cells. With their study published in the journal PLOS Biology the team lays the...

Nematicity is a new piece in double bilayer graphene phase diagram puzzle

Although twisted sheets of double bilayer graphene have been studied extensively the past few years, there are still pieces missing in the puzzle that is its phase diagram—the different undisturbed, ground states of the system. Writing in Nature Physics, Carmen Rubio-Verdú and colleagues have found a new puzzle piece: an electronic nematic phase.
