BioRescue produces primordial germ cells from northern white rhino stem cells – a world’s first for large mammals

Scientists have successfully created primordial germ cell-like cells (PGCLSs) from induced pluripotent stem cells of the northern white rhino Nabire, paving the way to produce artificial gametes. This breakthrough aims to prevent the extinction of the northern white rhinoceros and increase genetic diversity.

How livestock systems act as a reservoir for antimicrobial-resistant bacteria

A recent study found that livestock systems are a significant source of antimicrobial-resistant (AMR) bacteria and genes, which can spread to humans through contaminated manure. The researchers recommend ecosystem-wide surveillance and improved manure disposal practices to combat AMR on a global scale.

Researchers shed (laser) light on emerging water treatment technique

A team of researchers from the University of Rhode Island has discovered new details about the chemical reaction that occurs when ferrate is exposed to visible and ultraviolet light. The findings could help optimize the use of ferrate in water treatment applications, making it a promising option for smaller systems.

Study explores how "me-time" affects social interaction

A new study by University at Buffalo researchers explores how spending time alone affects social interaction, finding that solitude may not be restorative for all individuals. Those who seek solitude due to fear or dislike of social interactions experience increased anxiety when interacting with others on days with increased alone time.

Padgett named NSF BRITE Fellow

Jamie Padgett, a Rice University professor, has been awarded a $1 million grant from the National Science Foundation's BRITE Fellows program. With this funding, she will develop methods for infrastructure resilience modeling in response to uncertain, evolving conditions resulting from earthquakes, hurricanes, and other disasters.

Structural studies offer “how-to” guide for designing cancer drugs

Researchers have discovered the three-dimensional structure of phosphoinositide 3-kinase alpha (PI3Kα) and how it changes with cancer-associated mutations. This knowledge enables the design of targeted drugs that can specifically bind to mutated versions, potentially eliminating side effects associated with current PI3Kα inhibitors.

Aging is driven by unbalanced genes

Researchers found that longer genes are linked to longer lifespans and shorter genes to shorter lifespans, with aging causing a shift towards short genes. This imbalance leads to subtle changes in thousands of genes across various tissues, suggesting systems-level changes contribute to aging.

Cupric oxide exhibiting both magnetic and dielectric properties at room temperature

Researchers confirmed cupric oxide's multiferroic state at room temperature under high pressure using neutron diffraction. Thin films of precisely distorted crystals may exhibit such properties at ambient pressure. This discovery enables the development of next-generation memory devices and energy-efficient optical modulators.

Symbiotic CO2 sequestration

Researchers genetically engineered a microbial community that can convert CO2 into sugar and produce useful chemicals, effectively acting as a living carbon sink. The community, consisting of bacteria and cyanobacteria, produces chemicals with a negative carbon balance.

Evolution of bat wings and calls through 'foraging syndromes' allows diversity to flourish

Researchers found a close correspondence between bat species' wing shapes and their echolocation vocalizations, with both linked to foraging ecology. The study reveals distinct 'foraging syndromes' that have evolved repeatedly in each family, matching optimal evolutionary solutions for different habitats.

Next-generation SERD camizestrant significantly improves progression-free survival vs. fulvestrant in advanced ER+ HER2- breast cancer

The SERENA-2 trial found camizestrant significantly improves progression-free survival versus fulvestrant in patients with estrogen receptor-positive, HER2-negative breast cancer. Camizestrant demonstrates efficacy across various patient populations, including those with ESR1 mutations and prior CDK4/6 inhibitor treatment.
