Ecologists sound alarm on plastic pollution
Research led by ecologists at the University of Toronto examining plastic pollution entering oceans, rivers and lakes around the world annually, outlines potential impacts of various mitigation strategies over the coming decade. The researchers estimate the scale of human response needed to reduce future emissions and manage what's already floating around out there and recommend a fundamental shift to a framework based on recycling where end-of-life plastic products are valued rather than becoming waste.

Princeton scientists explain how diverse species coexist in microbial communities
In their paper appearing September 11, 2020 in the journal eLife, Princeton researchers Amir Erez, Jaime Lopez, Ned Wingreen and colleagues use mathematical modeling to explore how species diversity in a bacterial community is affected when the nutrients the microbes depend upon are only seasonally available.

New data processing module makes deep neural networks smarter
Artificial intelligence researchers have improved the performance of deep neural networks by combining feature normalization and feature attention modules into a single module that they call attentive normalization. The hybrid module improves the accuracy of the system significantly, while using negligible extra computational power.

Scientists identify gene family key to unlocking vertebrate evolution
New University of Colorado Boulder-led research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an important episode in evolution where new genes played a significant role in the evolution of novel traits in vertebrates.

Legacy high performance computing system seeds supercomputing excellence at UT Dallas
TACC's Stampede1 was one of the most powerful supercomputers in the U.S. for open science research from 2013 to 2017. In 2018, 20 racks were donated to UT Dallas through the UT Research Cyberinfrastructure initiative and became Ganymede, a resource for campus researchers. Through efforts by campus facilitators, the number of HPC users at UT Dallas grew from a few dozen to several hundred.

Major NSF grant accelerates development of the Giant Magellan Telescope
The GMTO Corporation has received a $17.5 million grant from the National Science Foundation (NSF) to accelerate the prototyping and testing of some of the most powerful optical and infrared technologies ever engineered. These crucial advancements for the Giant Magellan Telescope (GMT) at the Las Campanas Observatory in Chile will allow astronomers to see farther into space with more detail than any other optical telescope before.

Reaching 90% PL quantum yield in 1D metal halide by pressure-suppressed nonradiative loss
Here, we report a significant pressure-induced photoluminescence (PL) enhancement in a one-dimensional hybrid metal halide C4N2H14PbBr4, and the underlying mechanisms are investigated using in situ experimental characterization and first-principles calculations. Under a gigapascal pressure scale, the PL quantum yields (PLQYs) were quantitatively determined to show a dramatic increase from the initial value of 20% at ambient conditions to over 90% at 2.8 GPa.

A white dwarf's surprise planetary companion
For the first time, an intact, giant exoplanet has been discovered orbiting close to a white dwarf star. This discovery shows that it is possible for Jupiter-sized planets to survive their star's demise and settle into close orbits around the remaining stellar ember, near the habitable zone. This foretells one possible future for our own Solar System when the Sun ages into a white dwarf.

Next-gen organoids grow and function like real tissues
Bioengineers at EPFL have created miniature intestines in a dish that match up anatomically and functionally to the real thing better than any other lab-grown tissue models. The biological complexity and longevity of the new organoid technology is an important step towards enabling drug testing, personalized medicine, and perhaps, one day, transplantations.

Mapping cavefish brains leads to neural origin of behavioral evolution
While studied for nearly a century, little is known about how cavefish brains differ. A study is the first to look inside their brains with millimeter resolution to start to understand how the individual neurons and brain regions that drive complex behaviors, including sleep and feeding have evolved. This work has broad implications for the understanding of how brains evolve in many different animal models and is hoped to be widely used by the scientific community.

Marine animals live where ocean is most breathable, ranges may shrink with climate change
New research from the University of Washington shows that a wide variety of marine animals -- from vertebrates to crustaceans to mollusks -- already inhabit the maximum range of breathable ocean that their physiology will allow. The findings provide a warning about climate change: Since warmer waters will harbor less oxygen, some stretches of ocean that are breathable today for a given species may not be in the future.

Theoretically, two layers are better than one for solar-cell efficiency
Solar cells have come a long way, but inexpensive, thin film solar cells are still far behind more expensive, crystalline solar cells in efficiency. Now, a team of researchers suggests that using two thin films of different materials may be the way to go to create affordable, thin film cells with about 34% efficiency.

Ocean algae get 'coup de grace' from viruses
Scientists have long believed that ocean viruses always quickly kill algae, but Rutgers-led research shows they live in harmony with algae and viruses provide a 'coup de grace' only when blooms of algae are already stressed and dying. The study will likely change how scientists view viral infections of algae, also known as phytoplankton - especially the impact of viruses on ecosystem processes like algal bloom formation (and decline) and the cycling of carbon and other chemicals on Earth.
