Researchers aim X-rays at century-old plant secretions for insight into Aboriginal Australian cultural heritage
Thu, 26 May 2022 18:11:49 EDT
For tens of thousands of years, Aboriginal Australians have created some of the world's most striking artworks. Today their work continues long lines of ancestral traditions, stories of the past and connections to current cultural landscapes, which is why researchers are keen on better understanding and preserving the cultural heritage within. By revealing the chemistry of plant secretions, or exudates, recent studies build a basis for better understanding and conserving art and tools made with plant materials.

A large U.S. study shows 15 years of frozen egg thaw outcomes for women facing age-related fertility decline.
Discovery offers starting point for better gene-editing tools
Thu, 26 May 2022 15:18:06 EDT
New research has big implications for genomic medicine. Scientists have defined with atomic precision a new genome editing tool that is less than half the size of CRISPR-Cas9 -- currently the most reliable genome editing system. This new tool would allow scientists to fit genetic editors into smaller viral delivery systems to fix a variety of diseases.
How to tie-dye cotton with acorns and rust
Thu, 26 May 2022 15:18:03 EDT
Tie-dyeing is a fun activity that can spice up clothes with colorful patterns. Although kits are available in stores, nature provides dyes that can be extracted from items found in one's yard -- for example, acorns and rust. Researchers now present a 'green' process for tie-dyeing cotton with renewable resources and wastes that undergraduate students can easily do under minimal supervision. The activity links together science, art and sustainability.
Autonomous underwater imaging: Faster and more accurate
Thu, 26 May 2022 14:48:22 EDT
Recently conducted tests used new algorithms to outperform state-of-the-art programming for autonomous underwater sonar imaging, significantly improving the speed and accuracy for identifying objects such as explosive mines, sunken ships, airplane black boxes, pipelines and corrosion on ship hulls.
A synthetic antibiotic may help turn the tide against drug-resistant pathogens
Thu, 26 May 2022 14:15:31 EDT
A synthesized antibiotic derived from computer models of bacterial gene products appears to neutralize even drug-resistant bacteria. The compound, named cilagicin, works well in mice and employs a novel mechanism to attack MRSA, C. diff, and several other deadly pathogens.
Molecular profiling identifies new high-risk subtype of pediatric liver cancer
Thu, 26 May 2022 13:53:30 EDT
The characterization a new molecular type of high-risk pediatric liver cancer showed that these tumors had better outcomes when patients were treated by transplantation, rather than by chemotherapy and surgery alone.
Finding coherence in quantum chaos
Thu, 26 May 2022 13:53:27 EDT
A theoretical breakthrough in understanding quantum chaos could open new paths into researching quantum information and quantum computing, many-body physics, black holes, and the still-elusive quantum to classical transition.
New combined therapy helps extend lives of men with prostate cancer
Thu, 26 May 2022 12:57:53 EDT
Practice-changing research shows that a combination of androgen deprivation therapy -- a commonly used hormone injection -- plus pelvic lymph node radiation, kept nearly 90% of clinical trial patients' prostate cancer at bay for five years.
A unique catalyst paves the way for plastic upcycling
Thu, 26 May 2022 12:57:47 EDT
A recently developed catalyst for breaking down plastics continues to advance plastic upcycling processes. In 2020, scientists developed the first processive inorganic catalyst to deconstruct polyolefin plastics into molecules that can be used to create more valuable products. Now, the team has developed and validated a strategy to speed up the transformation without sacrificing desirable products.
Producers and consumers must share burden of global plastic packaging waste
Thu, 26 May 2022 12:57:45 EDT
Plastic packaging waste is everywhere. Our plastic bottles, food wrappings, and grocery bags litter the landscape and pollute the global environment. A new study explores the global patterns of plastic packaging waste. The study finds three countries -- the U.S., Brazil, and China -- are the top suppliers of waste.
Arc volcanoes are wetter than previously thought, with scientific and economic implications
Thu, 26 May 2022 12:21:41 EDT
The percentage of water in arc volcanoes, which form above subduction zones, may be far more than many previous studies have calculated. This increased amount of water has broad implications for understanding how Earth's lower crust forms, how magma erupts through the crust, and how economically important mineral ore deposits form, according to a new article.
New light shed on cell membranes
Thu, 26 May 2022 12:21:38 EDT
Researchers are using light in novel ways to better image biological samples.
Professional 'guilds' of bacteria gave rise to the modern microbiome
Thu, 26 May 2022 11:28:58 EDT
Even the smallest marine invertebrates -- some barely larger than single-celled protists -- are home to distinct and diverse microbial communities, or microbiomes, according to biologists. The study underscores that a vast diversity of animals have microbiomes, just as humans do. But more surprisingly, there's little correlation between how closely related most animals are and how similar their microbiomes are -- something widely assumed to be true based on the study of humans, larger mammals, and insects.
Study tracking T-cell activation over time boosts search for immune disease treatments
Thu, 26 May 2022 11:28:52 EDT
Researchers have identified links between 127 genes and immune diseases, providing newfound insights into the sequence and timing of gene activity during the activation of T cells, a key process in regulating the body's immune response.
Researchers hunt for one-pole magnets by combining cosmic rays and particle accelerators
Thu, 26 May 2022 11:28:48 EDT
Particle accelerators have helped researcher to draw new leading limits on the existence of magnetic monopoles from the collisions of energetic cosmic rays bombarding the Earth's atmosphere.
Fishing for new source of proteoglycans, an important health food ingredient
Thu, 26 May 2022 11:28:37 EDT
Chondroitin sulfate proteoglycans (CSPGs), commonly obtained from salmon nasal cartilage, are a key ingredient of various health foods. As the popularity of health foods increases, scientists are searching for alternative sources of CSPGs. Now, researchers have analyzed the PGs and their CS structures in the head cartilage of 10 edible bony fishes, including sturgeons. Their findings point to several new fishes that can serve as alternatives to salmon as a source of CSPGs.
Drug resistance molecule can spread though bacterial 'communities'
Thu, 26 May 2022 11:28:27 EDT
