A new species of ancient beaver that was rediscovered by researchers in The University of Texas at Austin’s fossil collections has been named after Buc-ee’s, a Texas-based chain of popular travel centers known for its cartoon beaver mascot. The beaver is called Anchitheriomys buceei, or “A. buceei” for short. Steve May, a research associate at the UT Jackson School of Geosciences, said that the beaver’s Texas connection and a chance encounter with a Buc-ee’s billboard are what inspired the name. May is the lead author of the paper that describes A. buceei, along with another, much smaller, species of fossil beaver. Published ...

HOUSTON – (March 27, 2023) – Rice University bioscientist and synthetic biologist James Chappell has won a National Science Foundation CAREER Award to develop RNA programming methods to improve human health and the environment. “Synthetic biology has progressed a lot in the past decade, and we’ve gotten really good at genetically programming microbes in confined laboratory environments where conditions are ideal,” said Chappell, an assistant professor both of biosciences and of bioengineering. “But, of course, most microbes on the planet don't live in pure cultures where the temperature is always 37 degrees ...

Scientists seeking a way to eliminate an adverse reaction to treatments for acute lymphocytic leukemia, a common childhood cancer, have found what they believe to be an early warning indicator. Mouse studies conducted by Rutgers researchers as part of a larger scientific team are pointing to vitamin A levels as a signal that a patient may or may not be vulnerable to a dangerous toxicity. Summarizing their findings in Science Translational Medicine, the scientists found that, in patients being treated for acute lymphocytic leukemia with the chemotherapy drug asparaginase, there is an ...

A subset of white blood cells, known as myeloid cells, can harbor HIV in people who have been virally suppressed for years on antiretroviral therapy, according to findings from a small study supported by the National Institutes of Health. In the study, researchers used a new quantitative method to show that HIV in specific myeloid cells—short-lived monocytes and longer-lived monocyte-derived macrophages—can be reactivated and infect new cells.

In addition to an antigen, many vaccines also contain substances, called adjuvants, which stimulate the immune system. By using computer-aided molecular design and machine learning, a Chinese research team has now developed two novel broad-spectrum adjuvants that can significantly amplify the immune response to vaccines. As reported in the journal Angewandte Chemie, they were able to enhance the effectiveness of immunization against certain forms of cancer in animal models. Adjuvants amplify and prolong the effect of vaccine immunizations. Aluminum salts have been successfully used ...

ITHACA, N.Y. – An international team of astronomers has found the atmospheric compositions of giant planets out in the galaxy do not fit our own solar system trend. Using NASA’s James Webb Space Telescope (JWST), the researchers discovered that the atmosphere of exoplanet HD149026b, a ‘hot Jupiter’ orbiting a star comparable to our sun, is super-abundant in the heavier elements carbon and oxygen – far above what scientists would expect for a planet of its mass. These findings, published in “High atmospheric metal enrichment for a Saturn-mass ...

When studying the brain, researchers are just beginning to use a method known as voltage imaging to track neural activity in the living animal. While this approach is a promising way to better understand neuron firing, behavior, and cognition, there are limitations and risk factors. The practice requires putting a lot of light into the brain (which can lead to overheating) and only has the capacity to image ten neurons at a time. New research from Jerry Chen, a Boston University College of Arts & Sciences assistant professor of biology, and collaborators aims to address these challenges. Published today in Nature Methods, ...

The community of microbes living in and on our bodies may be acting as a reservoir for antibiotic resistance, according to new research from the Earlham Institute and Quadram Institute in Norwich. The use of antibiotics leads to ‘collateral damage’ to the microbiome, ramping0 up the number of resistance genes being passed back and forth between strains in the microbiome. The findings also suggest these genes spread so easily through a population that, regardless of your own health and habits, the number of resistance genes in your gut is heavily influenced by national trends in antibiotic consumption. The rise of antimicrobial resistance (AMR) among human pathogens is widely seen ...
