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...

A large U.S. study shows 15 years of frozen egg thaw outcomes for women facing age-related fertility decline.

Astronomers have searched for extraterrestrial civilizations in planetary systems for sixty years, to no avail. In the paper published by International Journal of Astrobiology, Cambridge University Press, and titled "Migrating extraterrestrial civilizations and interstellar colonization: Implications for SETI and SETA," Irina K. Romanovskaya proposes that the search for extraterrestrial...

Humans have always had a complex relationship with rivers, which both fostered and threatened civilizations throughout history. Just recall Osiris, the ancient Egyptian god of death and rebirth, who was inextricably linked with the annual flooding of the Nile.

Each odd-year election cycle since 2017, four $25 democracy vouchers have arrived in the mail for registered voters in Seattle.

Seeing is believing—or, for scientists, the beginning of understanding. Researchers can visualize atomically small details with transmission electron microscopy (TEM) by beaming electrons through the sample and capturing their interactions to form an image. But such tiny specimens can evade the electrons, so they need to be specially treated with heavy metals to ensure interactions. To see...

It seemed like a straightforward question to biology professor Paul Mensink: Are plastic bags that hold curbside recyclables better or worse for the environment than blue boxes?

In a finding that has important ramifications for neurodegenerative disorders such as Alzheimer's disease, RIKEN researchers have discovered how three chaperone molecules in yeast cells work together to break up beta-sheet-rich fibrillar protein aggregates known as amyloid fibrils.

The recent string of mass shootings has once again captured the attention of the American public. The tragic shootings in an elementary school in Texas, a grocery store in New York, a church in California and locally in the streets of downtown Sacramento have many people wondering what can be done to prevent such tragedies.

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. In ACS's Journal of Chemical Education, researchers present a "green" process for tie-dyeing cotton with renewable resources and wastes that undergraduate students can easily...

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.

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...

Scientists link eggshell remains to giant Genyornis newtoni

Reducing levels of the nutrient phosphorus to control harmful algal blooms in places like Lake Erie is actually advantageous to toxic cyanobacteria strains, which can lead to an increase in toxins in the water, according to a new modeling study.

You don't have to be an engineer to know that water and electronics don't mix. But if you want to use a sensing circuit to study small-scale features in a community of cells, the electronics must find a way to accommodate the cell's aqueous environment. The circuit also cannot affect the cells in a way that invalidates the data.

Driven by technological, societal and political change, renewable energy technologies are progressively replacing fossil fuels.

CRISPR has ushered in the era of genomic medicine. A line of powerful tools has been developed from the popular CRISPR-Cas9 to cure genetic diseases. However, there is a last-mile problem—these tools need to be effectively delivered into every cell of the patient, and most Cas9s are too big to be fitted into popular genome therapy vectors, such as the adenovirus-associated virus (AAV).

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.

Nearly 22% of Republican legislators in the country have joined at least one far-right Facebook group, with Missouri ranking among the top five, a watchdog organization found in a study released this month.

In our solar system, there are several thousand examples of co-orbital objects: bodies that share the same orbit around the sun or a planet. The Trojan asteroids are such an example. We have not yet observed any similar co-orbitals in extrasolar systems, despite discovering more than 5,000 exoplanets. In a new study published in Icarus by Anthony Dobrovolskis, SETI Institute, and Jack Lissauer,...

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.

The federal suspension of prescribed burns pending a review of how recent fires lit during extreme drought escaped boundaries is reverberating in the West—and complicating Colorado efforts to revive ailing forests and reduce the severity of wildfires.

Designed to dive 1,000 metres and roam remote parts of the ocean, an autonomous vehicle was deployed in the Gulf of Alaska this spring to provide a deeper understanding of the ocean's chemistry in the era of climate...
