Once a favored food of grazing dinosaurs, an ancient lineage of plants called cycads helped sustain these and other prehistoric animals during the Mesozoic Era, starting 252 million years ago, by being plentiful in the forest understory. Today, just a few

New research from the University of Oxford has revealed that bumblebees cannot taste pesticides present in nectar, even at lethal concentrations. This means bumblebees are not able to avoid contaminated nectar, putting them at high risk of pesticide expos

The internal clocks of grizzly bears appear to keep ticking through hibernation, according to a genetic study. This persistence highlights the strong role of circadian rhythms in the metabolism of many organisms including humans.

Common oral infections, periodontal diseases and caries, are associated with inflammatory metabolic profiles related to an increased risk of cardiometabolic diseases, a new study by an international team of researchers suggests. Oral infections a

The return of the grey wolf (Canis lupus) to Germany, which began 23 years ago in the region of Lusatia in Eastern Germany, is a process of great ecological and social significance. Therefore, a precise understanding of the recolonisation of the original

Many songbirds are nesting earlier in spring because of warmer temperatures brought about by climate change. But the shift brings another danger that is especially deadly for nestlings: greater exposure to temperature variability in the form of cold snaps

Natural carbon reservoirs will play a major role at the COP28 world climate conference in the United Arab Emirates. After oceans and soils, forests are the largest "sinks" for carbon, i.e. they absorb an enormous amount of carbon dioxide from the atmosp

Every cell in the human body contains the same genetic instructions, encoded in its DNA. However, out of about 30,000 genes, each cell expresses only those genes that it needs to become a nerve cell, immune cell, or any of the other hundreds of cell types

There is a lively exchange of genetic information between the numerous microorganisms in the oceans. This so-called horizontal gene transfer (HGT) is crucial for the evolution of many organisms and is, for example, also the most important mechanism for th

CITE-seq (cellular indexing of transcriptomes and epitopes) is an RNA sequencing-based method that simultaneously quantifies cell surface protein and transcriptomic data within a single cell readout. The ability to study cells concurrently offers unpreced

Microbial communities are thought to contain keystone species, which can disproportionately affect the stability of the communities, even if only present in low abundances. Identifying these keystone species can be challenging, especially in the human gut

Some patients with myelodysplastic syndromes, like acute myeloid leukemia, benefit from a chemotherapy drug called decitabine that stunts cancer growth. But many others are resistant to decatibine's effects or become resistant over time. Wilmot Cancer In
