Seeing through the fog: Pinpointing young stars and their protoplanetary disks
Imagine walking through a dense, hazy fog in the middle of the night, seeing patches of light from cars and towns shimmering in the distance. It's nearly impossible to tell if the lights are deep in the fog or beyond it. Astronomers trying to find young stars face a similar problem: the light from stars they're hunting is shimmering through great big regions of hazy gas and dust in space, called...
New NSF program hopes to rev the nation’s ‘engines’ of innovation
Regional centers would get $160 million each to translate research into high-tech jobs and boost local economies
New method melds data to make a 3-D map of cells' activities
Just as it's hard to understand a conversation without knowing its context, it can be difficult for biologists to grasp the significance of gene expression without knowing a cell's environment. To solve that problem, researchers at Princeton Engineering have developed a method to elucidate a cell's surroundings so that biologists can make more meaning of gene expression information.
Majority of Detroiters report stable, improved financial situation compared to a year ago
Two years into the pandemic, 72% of Detroit residents say their financial situation has stabilized or improved compared to a year ago, and there's evidence that stimulus checks and the expanded Child Tax Credit played a role in reducing Detroiters' experiences of economic hardship.
Big tractors, now heavier than many dinosaurs, can damage deep soil
Intense mechanization is efficient, but may crush the root zone and lessen harvests
Unraveling the genetic keys to improve canola crop yield
An international team of researchers, including one from The University of Western Australia (UWA), has successfully unraveled the genomes of 418 unique samples of rapeseed from across the globe to identify traits that breeders can use to improve crop yield.
Research team improves gene editing with chemical process
The gene-editing technique known as CRISPR has accelerated biological and medical research in the last decade by allowing scientists to repair the DNA of human cells almost as simply as using a pair of scissors.
Whale carcass proves tasty snack for beetles
A total of 21 new beetle species were discovered in the whale carcass that washed ashore at the Rottumerplaat in 2020. The creatures are experts in consuming meat, skin and bones.
New theory promises to reshape how we think about polymer superstructures

Polymer scientists recently announced that they have solved a longstanding mystery surrounding a nanoscale structure, formed by collections of molecules, called a double-gyroid. This shape is one of the most desirable for materials scientists, and has a wide range of applications; but, until now, a predictable understanding of how these shapes form has eluded researchers.
Shaping the future of light through reconfigurable metasurfaces
The technological advancement of optical lenses has long been a significant marker of human scientific achievement. Eyeglasses, telescopes, cameras, and microscopes have all literally and figuratively allowed us to see the world in a new light. Lenses are also a fundamental component of manufacturing nanoelectronics by the semiconductor industry.
New theory promises to reshape how we think about polymer superstructures
Polymer scientists at the University of Massachusetts Amherst recently announced in the journal Nature Communications that they have solved a longstanding mystery surrounding a nanoscale structure, formed by collections of molecules, called a double-gyroid. This shape is one of the most desirable for materials scientists, and has a wide range of applications; but until now, a predictable...
Archaeology illuminates Chinese businesses in Eugene, Oregon
Uncovering the past of historically under-represented communities sometimes means having to do a little digging, through newspapers, archives and even the ground.
How hybrid plant varieties could address the challenges of food security and climate change
Hybrid agricultural and horticultural crops can play an important role in supporting global food security. They produce higher yields and are often more resistant than non-hybrid varieties to diseases and climate stress. But for many crops, no hybrid varieties are available. Why is that?
Shaping the future of light through reconfigurable metasurfaces

Harnessing the power of 'phase-change' materials, researchers have demonstrated how reconfigurable metasurfaces -- artificial materials with extraordinary optical properties -- are crucial to the future of nanotechnology.
Stimulating brain circuits promotes neuron growth in adulthood, improving cognition and mood

Scientists working in the vast Amazon Basin have contributed more than 57,000 camera trap images for a new study.
Scientists provide more than 57,000 camera trap images for massive study on Amazon wildlife
Wildlife Conservation Society (WCS) scientists working in the vast Amazon Basin have contributed more than 57,000 camera trap images for a new study published in the journal Ecology by an international team of 120 research institutions.
New trait-based approach to global change ecology moves from description to prediction
It's not enough to understand what the effects of climate change are. Society needs ways to get ahead of these changes, to predict them before they actually happen. And when it comes to conservation, the approach scientists use to study species in the wild could be critical to these predictions, according to a recent research review led by biologist Stephanie Green and published in Proceedings of...
Study sheds new light on the mechanism of individual cell memory, using yeast as a model
Whi3 is a mnemon (Whi3mnem), or in other words, a protein that stores information in individual cells by forming stable super-assemblies. This memory state is then inherited by only one individual daughter cell at mitosis (individual memory). For example, when facing an uncommitted mating partner, budding yeast cells coalesce the G1/S inhibitor Whi3 into a dominant mnemon super-assembly that...
'Homo sapiens is too arrogant: Call us Homo faber, the toolmaker'
We need to dispel the arrogant and misguided idea that modern humans are superior to earlier human species. It is thanks in part to all our predecessors such as Neanderthals that we are who we are today. This is according to Marie Soressi, Professor of Hominin Diversity Archaeology.
