Samples from Huanan Seafood Market provide further evidence of COVID-19 animal origins

2024-09-19

A new international study provides a shortlist of the wildlife species present at the market from which SARS-CoV-2, the virus responsible for the COVID-19 pandemic, most likely arose in late 2019. The study, published Thursday in the journal Cell, is based on an analysis of genetic data released by the Chinese Center for Disease Control and Prevention. The data comes from more than 800 samples collected in and around the Huanan Seafood Wholesale market in Wuhan, China, beginning on Jan. 1, 2020, and from viral genomes from early COVID-19 patients. "This may be the last big, new set of data directly from ...

City of Hope vaccine experts report positive results on Phase 1 trial of personalized vaccine for lymphoplasmacytic lymphoma

2024-09-19

LOS ANGELES — A team of researchers from City of Hope®, one of the largest and most advanced cancer research and treatment organizations in the U.S., and The University of Texas M.D. Anderson Cancer Center, have reported safety and efficacy results from a Phase 1 trial that featured a personalized vaccine to treat lymphoplasmacytic lymphoma, a rare and slow-growing type of blood cancer, according to a study published recently in Nature Communications. The current approach to lymphoplasmacytic lymphoma care is active surveillance of a patient’s possible symptoms. ...

Global assessment: How to make climate adaptation a success

2024-09-19

Climate change is forcing people to adapt to changing environmental conditions. But what really makes the difference is how they do it. The recently published Hamburg Climate Futures Outlook 2024 by 73 authors shows that, in the long run, only sustainable adaptation can succeed. This global assessment by University of Hamburg’s Cluster of Excellence Climate, Climatic Change, and Society (CLICCS) also provides practical recommendations. “Successfully adapting to the impacts of climate change is just as difficult and challenging as reducing emissions of every kind,” says Anita Engels, Professor of Sociology ...

The African Engineering and Technology Network signs eighth university partner

2024-09-19

Carnegie Mellon University Africa announced today that the African Engineering and Technology Network (Afretec) has signed its eighth university partner, Al Akhawayn University. The network, launched in 2022, provides a vehicle for technology-focused universities in Africa to engage in deep collaboration to drive inclusive digital growth, create technology development and job growth, and shape policy change. Afretec Network members span the entire continent and include Carnegie Mellon University Africa, the American University in Cairo, Université Cheikh ...

Researchers awarded $1.14M to use artificial intelligence to determine best rectal cancer treatment strategy

2024-09-19

CLEVELAND—With a new four-year, $1.14 million grant from the U.S. Department of Veterans Affairs, researchers at Case Western Reserve University and the Louis Stokes Cleveland VA Medical Center, will use artificial intelligence (AI) to determine the best personalized treatment for Veterans with rectal cancer. Colorectal cancers are the third-most common type of cancer in military personnel, affecting up to 8% of Veterans and 5% of active-duty Service members, according to the American Cancer Society (ACS). More than 152,000 patients in the United States will be diagnosed with colorectal cancer in 2024, with more than 46,000 localized ...

A new ventilator-on-a-chip model to study lung damage

2024-09-19

COLUMBUS, Ohio – For the first time, scientists are able to directly compare the different kinds of injury that mechanical ventilation causes to cells in the lungs. In a new study, using a ventilator-on-a-chip model developed at The Ohio State University, researchers found that shear stress from the collapse and reopening of the air sacs is the most injurious type of damage. This miniature “organ-on-a-chip” model simulates not only lung injury during mechanical ventilation, but also repair and recovery, in human-derived cells in real time, said co-lead author ...

Enrollment of undocumented students at California universities dropped from 2016 to 2023

2024-09-19

Enrollment of low-income, undocumented students declined by half at University of California and California State University campuses from 2016 through the 2022-23 academic year, according to a new study by the University of California Civil Rights Project at UCLA and UC Davis School of Law. The paper, “‘California Dreamin’: DACA’s Decline and Undocumented College Student Enrollment in the Golden State” is believed to be the first to report on data collected during an era marked by increasing limitations on DACA, or Deferred Action for Childhood Arrivals. Further, researchers found, for UC and CSU low-income undocumented ...

Gaining insights into the chemical basis of aversive learning

2024-09-19

One of the things that makes brains so incredibly difficult to understand is their ability to adjust and adapt. Our learning experiences can set off complex signaling cascades that reshape neurons—and their synaptic connections—at the cellular level. For example, in mammals, scientists have established that activation of the N-methyl-D-aspartate receptor (NMDAR) and the ensuing calcium ion (Ca2+)-dependent signaling cascade is essential for postsynaptic remodeling and learning. As one might reasonably expect, ...

Revolutionary visible-light-antenna ligand enhances samarium-catalyzed reactions

2024-09-19

Samarium (Sm), a rare earth metal, is important to organic chemists because of the ability of its divalent compounds to efficiently perform single-electron transfer reductions. Samarium iodide (SmI2) is moderately stable and can operate under mild conditions at room temperature, making it highly useful for producing pharmaceuticals and biologically active materials. However, most reactions require SmI2 in quantities equal to or greater than the stoichiometric amount and necessitate the use of harmful chemicals, making the process resource-intensive and expensive to manage. Several approaches have been studied to reduce ...

Stopping plants from passing viruses to their progeny

2024-09-19

Scientists have learned how plants keep viruses from being passed to their offspring, a finding that could ensure healthier crops. The discovery could also help reduce the transmission of diseases from mothers to human children. Plant viruses are often able to spread from one country to another through the seed trade. As a result, parent-to-progeny disease transmission is of global concern. “Viruses can hide in seeds for years, making this one of the most important issues in agriculture,” said UC Riverside distinguished professor Shou-Wei Ding in the Department of Microbiology and Plant Pathology. Ding is corresponding author of a new paper about the ...
