Revealing how hematopoietic stem cells acquire malignant traits in cancer

Scientists from Lund University’s Faculty of Medicine have discovered a novel mechanism connecting ribonucleic acid (RNA) metabolism to the development of leukemia in patients with myelodysplastic syndrome (MDS).

Merging cryo-TEM and tomography methods to reveal 3D morphology of dendrites

Documenting the lithiation process in TEM can provide a deep understanding of the electrode degradation mechanism during battery cycling, which enhances material modification for improved performance. The research was guided by Prof. Dong Su (Institute of Physics, Chinese Academy of Sciences).

Transforming the natural mineral shells of algae into functional perovskites

Perovskites are materials that are increasingly popular for a wide range of applications because of their remarkable electrical, optical, and photonic properties.

Mesophotic coral reefs function differently than their shallower counterparts, study shows

In a paper published today in Current Biology, researchers from the California Academy of Sciences Hope for Reefs initiative, along with Brazilian collaborators from the University of São Paulo, Federal University of Espírito Santo, and the Instituto Nacional da Mata Atlântica, show that mesophotic coral reefs function much differently than their shallower counterparts and are unlikely to offer a refuge for shallow water fishes trying to escape climate-change driven warming on the ocean's surface.

New class of oral drugs inhibits a diverse range of SARS-CoV-2 strains

The constant evolution of new COVID-19 variants makes it critical for clinicians to have multiple therapies in their arsenal for treating drug-resistant infections. Researchers have now discovered that a new class of oral drugs that acts directly on human cells can inhibit a diverse range of pathogenic SARS-CoV-2 strains.

Study investigates the complex evolutionary history of jewel beetles' vision

Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. Possessing large, well-developed eyes, jewel beetles use vision and color for a range of different behaviors, including finding mates and host plants.

The mechanism behind fruit fly germ cells forming ring canals

Cell division is the process through which the majority of cells in the bodies of living beings duplicate their contents and physically split into new cells.

Antibiotic usage in livestock leaves an impact on soil carbon and climate

Soils are dependable carbon sinks, which is critical for minimizing the consequences of climate change. Grazing by large mammals promotes soil carbon storage in grasslands, but livestock is progressively replacing wild herbivores across the world.

Investigating the potential cellular effects of C-reactive protein

The biological function of the C-reactive protein, CRP, has long been unidentified. Investigators at LiU have discovered that this protein has a useful function in the inflammatory disease systemic lupus erythematosus or SLE.

Study shows mothers provide necessary microbes to babies born via cesarean

Can newborns delivered by cesarean surgery lack vital microbes? Recent data suggests that “no” could be the answer. Mothers are able to transmit bacteria to their babies through alternative, compensating channels, according to research published in the journal Cell Host & Microbe on March 8th, 2023.

Pentamer shape of C-reactive protein can suppress the immune response in inflammatory disease

The biological function of the C-reactive protein, CRP, has long been unknown. Researchers at Linköping University in Sweden now show that this protein has a beneficial function in systemic lupus erythematosus, SLE, an inflammatory disease.

New gene resource for improving root systems

A strong root system allows crops to absorb water and nutrients from the soil, but scientists have little information about the genes that control root development. Recent research published in New Phytologist reveals that blocking a negative regulator gene of root development leads to enhanced root growth in plants.

Discovery could establish an effective control environment for chromosome instability

A research team, affiliated with UNIST has unveiled a key factor involved in the DNA damage response (DDR), homologous recombination (HR) and DNA interstrand crosslink (ICL) repair.

Quantitative method evaluates sexual conflict evolution

Males of a species that evolve sexual conflict traits can create issues for females and, eventually, the entire population.

Largest-ever genetic analysis provides insight into domestications and origin of traits in grapevine

In the largest ever genetic analysis of grapevine varieties, including samples from previously undocumented specimens in private collections, researchers provide new insights into how, when, and where wine and table grapevines were domesticated, which has been a longstanding question.

Study shows like-minded flamingos form cliques

Flamingos form cliques of like-minded individuals within their flocks, new research shows.

Elaborating how amino acids shaped the genetic code of ancient microbes

Researchers discovered that without specific amino acids, ancient proteins would not have identified how to evolve into anything alive on the planet today, including plants, animals, and humans, by mimicking early Earth conditions in the lab.

Study reveals why the FMO5 gene produces an enzyme with a different activity

Our body produces lots of enzymes that break down toxic substances. One class of such enzymes are the flavin-containing monooxygenases (FMOs), which are present in all tetrapods. Humans have five different FMO genes, of which the first four display the same activity. However, the fifth FMO gene triggers a different breakdown reaction. University of Groningen biochemists have succeeded in resurrecting the ancestral genes of all tetrapod FMOs to show how this divergence has occurred. Their results appear on 24 February in Nature Communications.
