Expanding a child’s heart implant with light
2024-08-19
DENVER, Aug. 19, 2024 — Children born with defects that impair the heart’s lower chambers undergo a series of invasive surgeries early in life. The first surgery includes implantation of a plastic tube called a shunt to improve blood flow. However, as children grow, the shunt is often replaced to accommodate their changing bodies. Now, researchers have designed a shunt that expands when activated by light. If developed successfully, this device could reduce the number of open-chest surgeries these children receive.
The researchers will present their results at the fall meeting of the American Chemical Society (ACS). ACS Fall 2024 ...
New insights on how bird flu crosses the species barrier
2024-08-19
In recent years, public health measures, surveillance, and vaccination have helped bring about significant progress in reducing the impact of seasonal flu epidemics, caused by human influenza viruses A and B. However, a possible outbreak of avian influenza A (commonly known as ‘bird flu’) in mammals, including humans, poses a significant threat to public health.
The Cusack group at EMBL Grenoble studies the replication process of influenza viruses. A new study from this group sheds light on the different mutations that the avian influenza virus can undergo to be able to replicate in mammalian cells.
Some avian influenza ...
Energy companies pressure landowners into fracking, study shows
2024-08-19
BINGHAMTON, N.Y. -- Energy companies use persistent and personalized pressure to get landowners to give permission for hydraulic fracturing (fracking), and even when landowners decline, companies use legalized compulsion to conduct fracking anyway, according to a new study led by researchers at Binghamton University, State University of New York and UNLV.
“Hydraulic fracturing is a controversial issue, but a lot of the controversy has been focused on the big-picture consequences, for the climate and the economy,” said Benjamin Farrer, lead author and former PhD student at Binghamton University. “One of our hopes for this paper is that it will encourage policymakers ...

Peering into the mind of artificial intelligence to make better antibiotics
2024-08-18
DENVER, Aug. 18, 2024 — Artificial intelligence (AI) has exploded in popularity. It powers models that help us drive vehicles, proofread emails and even design new molecules for medications. But just like a human, it’s hard to read AI’s mind. Explainable AI (XAI), a subset of the technology, could help us do just that by justifying a model’s decisions. And now, researchers are using XAI to not only scrutinize predictive AI models more closely, but also to peer deeper into the field of chemistry.
The researchers will present ...
Evidence stacks up for poisonous books containing toxic dyes
2024-08-18
DENVER, Aug. 18, 2024 — If you come across brightly colored, cloth-bound books from the Victorian era, you might want to handle them gently, or even steer clear altogether. Some of their attractive hues come from dyes that could pose a health risk to readers, collectors or librarians. The latest research on these poisonous books used three techniques — including one that hasn’t previously been applied to books — to assess dangerous dyes in a university collection and found some volumes may be unsafe to handle.
The researchers will present their results at the fall meeting of the American Chemical Society (ACS). ACS Fall 2024 is a hybrid meeting being ...
Novel photoreceptor sheds light on how cyanobacteria see color
2024-08-17
Tokyo, Japan – Scientists from Tokyo Metropolitan University have identified a new photoreceptor in cyanobacteria with a modification in part of its structure which makes it sensitive to green/teal light. The photoreceptor belongs in a family usually sensitive to red/green light in the environment. They identified the parts of its amino acid structure responsible for this behavior; editing them helped restore sensitivity to red and green light, a remarkable example of molecular “plasticity” in action.
Cyanobacteria, also known as blue-green algae, are phenomenally important players ...
The bee’s knees: New tests created to find fake honey
2024-08-17
Researchers led by Cranfield University have developed new ways to detect sugar syrup adulteration in honey, paving the way for fast and accurate tests to discover fake products.
There is growing consumer demand for honey, with £89.8 million worth of honey imported to the UK in 2023. But as a high-value product it is vulnerable to fraud, with syrups added to dilute the pure honey – a report from the European Commission in 2023 found 46% of 147 honey samples tested were likely to have been adulterated with cheap plant syrups.
Because honey’s characteristics vary due to sources of nectar, season of harvest and ...

Researchers investigate parent perceptions of virtual learning
2024-08-16
In response to the COVID-19 pandemic, a majority of schools across the U.S. shifted to virtual learning. In a new study, published in Social Education Research, researchers conducted interviews with parents of students who attended middle or high schools to understand how virtual learning impacted their daily routines, stress levels, and the academic performance of the children.
The transition to virtual learning necessitated the creation of online lessons in a very short time period and with limited training of teachers. As a result, parents and students had to deal with unexpected changes in their home lives and learning environments.
“Virtual learning will not be limited ...
Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia
2024-08-16
Previous scientific studies have indicated that North American dog lineages were replaced with European ones between 1492 and the present day. To better understand the timing of this replacement, researchers from the University of Illinois Urbana-Champaign and the University of Iowa sequenced mitochondrial DNA from archaeological dogs. Their findings suggest a complex social history of dogs during the early colonial period.
Europeans and Native Americans valued their dogs as companion animals, using them for similar work and as symbols of identity. Consequently, ...

Decoding mysterious seismic signals
2024-08-16
For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth’s lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds.
The origin the precursor signals, which arrive ahead of the main seismic waves that travel through Earth’s core, has remained unclear, but research led by University of Utah geophysicists sheds new light on this mysterious seismic energy.
PKP precursors appear to propagate from places deep below North America and the western Pacific and possibly bear an association with “ultra-low velocity zones,” thin layers ...
