Cross-linked polymers are structures where large molecular chains are linked together, allowing exceptional mechanical properties and chemical resistance to the final product. However, their modification is not easy. Now, scientists at Tokyo Institute of Technology develop a method that allows the fusion of different polymers together easily, allowing the precise tuning of the properties of the final material by selecting appropriate base polymers and mixing them at the right proportion.

In the Pacific Northwest, the range expansion of Barred Owls has contributed to a conservation crisis for Northern Spotted Owls, which are being displaced from their old-growth forest habitat. How will this interaction between species play out in the Sierra Nevada, where Barred Owls are just starting to move into the range of the California Spotted Owl? New research published in The Condor: Ornithological Applications suggests that wildlife managers may still be able to head off similar problems in critical areas of the Golden State -- if they act now.

Mathematicians, physicists, and materials experts might not spring to mind as the first people to consult about whether you are brewing your coffee right. But a team of such researchers from around the globe--the United States, the United Kingdom, Ireland, Australia, and Switzerland--are challenging common espresso wisdom, finding that fewer coffee beans, ground more coarsely, are the key to a drink that is cheaper to make, more consistent from shot to shot, and just as strong. Their work appears January 22 in the journal Matter.

Mathematicians, physicists and materials experts might not spring to mind as the first people to consult about whether you are brewing your coffee right.

But a team of such researchers including Dr Jamie Foster, a mathematician at the University of Portsmouth, are challenging common espresso wisdom.

They have found, that fewer coffee beans, ground more coarsely, are the key to a drink that is cheaper to make, more consistent from shot to shot, and just as strong.

The study is published in the journal Matter.

Caused by a herpesvirus, fibropapillomatosis (FP) is the most significant infectious disease affecting sea turtle populations worldwide. It is widespread in warmer climates like Florida, where almost 70 percent of sea turtles in a population have FP in some places; it has been documented in the Caribbean, South America, Hawaii, Japan, Australia, and beyond. The disease leads to the formation of tumors on the turtles' eyes, flippers and internal organs, which often debilitate them by inhibiting feeding and movement, obscuring vision, and/or leading to organ failure.

Curtin University scientists have discovered Earth's oldest asteroid strike occurred at Yarrabubba, in outback Western Australia, and coincided with the end of a global deep freeze known as a Snowball Earth.

The research, published in the leading journal Nature Communications, used isotopic analysis of minerals to calculate the precise age of the Yarrabubba crater for the first time, putting it at 2.229 billion years old - making it 200 million years older than the next oldest impact.

Permafrost, the perennially frozen subsoil in Earth's northernmost regions, has been collecting and storing plant and animal matter since long before the last Ice Age. The decomposition of some of this organic matter naturally releases carbon dioxide (CO2) into the atmosphere year-round, where it is absorbed by plant growth during the warmer months.

Experts' interest in utilizing gene editing for the breeding crops has seen revolutionary growth. Meanwhile, people's awareness for food safety has also been increasing. To understand the attitudinal difference among experts and public towards gene-edited crops, a team of Japanese researchers, led by Dr.

Ocean currents are essential for the global distribution of heat and thus also for climate on earth. For example, oxygen is transferred into the deep sea through the formation of new deep water around Antarctica. Weddell Sea sourced Antarctic Bottom Water (AABW) normally spreads northwards into the South Atlantic and Indian Oceans. However, during the peak of the last two ice ages, the supply of deep water from the Weddell Sea to the South Atlantic Ocean was apparently interrupted, as shown by a new study led by scientists of the GEOMAR Helmholtz Centre for Ocean Research Kiel.

A new high-throughput method has revealed metals previously undetected in 3-D protein structures. The study, led by the Universities of Surrey and Oxford, is thought to have major implications for scientists using protein structure data.

Police have long relied on the unique whorls, loops or arches encoded in fingerprints to identify suspects. However, they have no way to tell how long ago those prints were left behind -- information that could be crucial to a case. A preliminary new study in ACS' Analytical Chemistry suggests that could change. Researchers report that they could link compounds contained in fingerprints with their age.   

WASHINGTON, January 22, 2020 - Since 1880, the Earth's temperature has risen by 1.9 degrees Fahrenheit and is predicted to continue rising, according to the NASA Global Climate Change website. Scientists are actively seeking to understand this change and its effect on Earth's ecosystems and residents.

Cavities, or dental caries, are the most widespread non-communicable disease globally, according to the World Health Organization. Having a cavity drilled and filled at the dentist's office can be painful, but untreated caries could lead to worse pain, tooth loss, infection, and even illness or death. Now, researchers in ACS Applied Materials & Interfaces report a bioactive peptide that coats tooth surfaces, helping prevent new cavities and heal existing ones in lab experiments.

BINGHAMTON, N.Y. - Your choice of clothing could affect the behavioral habits of wildlife around you, according to a study conducted by a team of researchers, including faculty at Binghamton University, State University of New York.

Experimental data and computer simulations come together to provide an innovative technique able to characterise the different configurations of an RNA molecule. The work, published in Nucleic Acids Research, opens new roads to study dynamic molecular systems.
