Uranium signatures in turtles and tortoises near nuclear testing and waste sites

Uranium signatures in turtles and tortoises near nuclear testing and waste sites
2023-08-22
(Press-News.org) The shells of turtles, tortoises, and sea turtles keep growing as long as the animals live—and some of them live a remarkably long time. Cyler Conrad and colleagues analyzed the shells of five specimens from areas that potentially accumulated anthropogenic uranium through nuclear fallout and/or waste. Unusual uranium signatures were found in a green sea turtle from Enewetak Atoll in the Republic of the Marshall Islands, a desert tortoise from southwestern Utah near the Nevada National Security Site (formerly known as the Nevada Test Site), a river cooter from the Savannah River Site in South Carolina, and a box turtle from Oak Ridge, Tennessee, where nuclear weapons work was conducted after World War Two. The turtle from Enewetak Atoll was collected in 1978, around 20 years after the end of nuclear testing at the site. The researchers speculate that cleanup activities may have stirred up contaminated sediment—but add that legacy contamination present in the atoll lagoon is also a possibility. Separate samples from different shell layers of the eastern box turtle collected from Oak Ridge in 1962 told a temporal story of its uranium exposure. The box turtle’s most contaminated shell layer was the one it was born with, suggesting even higher contamination levels in its mother. The legacies of 20th century nuclear deployment, testing, and production still amble and swim among us—and chelonian shells could be used as environmental monitors, according to the authors.

Australia experiences intense surge in Strep A cases, similar to northern hemisphere wave

2023-08-22
Australia has experienced an intense surge in severe Strep A cases, similar to the northern hemisphere wave, despite differences in seasons and circulating respiratory viruses, according to a new study. The national research project, involving researchers from Murdoch Children’s Research Institute and published in The Lancet Regional Health - Western Pacific, highlighted how the unseasonal increase in case load across the southern hemisphere adds to the need for a safe and effective vaccine against Strep ...

Coffee offers performance boost for concrete

Coffee offers performance boost for concrete
2023-08-22
Engineers in Australia have found a way of making stronger concrete with roasted used-coffee grounds, to give the drink-additive a “double shot” at life and reduce waste going to landfills. Lead author Dr Rajeev Roychand from RMIT University said the team developed a technique to make concrete 30% stronger by turning waste coffee grounds into biochar, using a low-energy process without oxygen at 350 degrees Celsius. “The disposal of organic waste poses an environmental challenge as it emits large amounts of greenhouse gases including methane and carbon dioxide, which contribute to climate change,” ...

As city heat rises, bird diversity declines

As city heat rises, bird diversity declines
2023-08-22
Hangzhou, China & Ithaca, N.Y.—Humans aren't the only ones leaving town when city heat becomes unbearable. A study done on 336 cities in China concludes that heat-retaining buildings and paved surfaces are directly related to a loss in bird diversity. These findings from scientists at Zhejiang University and the Cornell Lab of Ornithology are published in the journal Science of the Total Environment. “The heat-retention characteristic of cities is a well-known phenomenon called the urban heat island ...

Cancel Cervical Cancer – In Conversation with Brazil, Colombia, and Uruguay Experts | BGI Insights
2023-08-22
Despite being highly preventable, the Pan American Health Organization estimates cervical cancer kills 35,700 women annually in the Americas, and 80 percent of these cases are in Latin America and the Caribbean (LAC). The recently released BGI Genomics 2023 Global State of Cervical Cancer Awareness Report reveals potential awareness gaps that may contribute to this disproportionate distribution of cervical cancer cases in these regions. To offer greater insight into the steps needed to improve cervical ...

A calculator to predict benefit from adjuvant transarterial chemoembolization for hepatocellular carcinoma
2023-08-22
Hepatocellular carcinoma (HCC) is the most commonly diagnosed cancer of the liver and the fourth leading cause of cancer-related mortality worldwide, with China accounting for over half of the global annual cases and deaths. Hepatectomy is the standard curative-intent treatment option for appropriately selected patients with localized HCC. However, the high postoperative recurrence rate causes many patients to have a poor prognosis and a high incidence of cancer-specific death. This occurs in especially early recurrence within the first year after surgery, which is most likely due to occult micro-metastasis from the original tumor. Given that survival among patients with recurrence is markedly ...

Paired liver exchange developed by Boston College economists results in first four-way liver exchange

Paired liver exchange developed by Boston College economists results in first four-way liver exchange
2023-08-22
Chestnut Hill, Mass. (8/22/2023) – In a breakthrough in liver transplantation that may lead to the ability to connect more living donors and patients, a new matching system designed by a team led by Boston College economists enabled the world’s first four-way liver exchange and a cascade of additional matches, researchers reported recently in the American Journal of Transplantation. The results show that expanding the capacity of the donor-patient matching mechanism beyond the traditional 2-way change – matching two patients with two donors – can increase the number of ...

Understanding river alteration via shifting flow regime

Understanding river alteration via shifting flow regime
2023-08-22
Researchers at the Korea Institute of Civil Engineering and Building Technology (KICT, President Kim Byung-suk) published their findings on the drastic short-term alterations in rivers accompanied by shifts in vegetation and geomorphology drawn from actual on-site investigation and analyses and not from model simulations. The alteration processes from a 'white river,' characterized by riverbeds with no vegetation including bare sandbars, to a densely vegetated 'green river' with grass and trees, have been ...

Want to increase resiliency in kids? Teach creativity

2023-08-22
COLUMBUS, Ohio – Train elementary school students how to be creative and you can help increase their resilience in the face of real-life problems, new research suggests.   In a small study, researchers trained third, fourth and fifth graders to use literary techniques such as perspective shifting, counter-factual (what if) thinking and causal (why) thinking to improve creativity in dealing with difficulties.   The techniques helped kids come up with new, creative and practical ways to solve problems, said Angus Fletcher, lead author of the study and a professor of English at The Ohio State University and member of the university’s Project ...
