Evolution: No social distancing at the beginning of life

Bacteria are a dominant form of life that inhabit every environment on Earth. This includes human bodies, where they outnumber our cells and genes and regulate many body systems. Bacteria are regularly viewed as simple, single-celled ...

Bringing new energy to mitochondria research

Tiny mitochondria in our cells turn oxygen and nutrients into usable energy in a process called respiration. This process is essential for powering our cells, and yet in spite of its importance many of the finer details of ...

New insight into mammalian stem cell evolution

The genes regulating pluripotent stem cells in mammals are surprisingly similar across 48 species, Kyoto University researchers report in the journal Genome Biology and Evolution. The study also shows that differences among ...

Evolution in real-time: How bacteria adapt to their hosts

Bacteria that invade animal cells in order to multiply are widespread in nature. Some of these are pathogens of humans and animals. In the environment, they are often found inside unicellular organisms. A research team led ...

DNA damage triggers reprogramming into stem cells

A joint research team from the National Institute for Basic Biology (NIBB) in Japan, Huazhong Agricultural University in China, and the Czech Academy of Sciences in the Czech Republic has discovered that DNA damage causes ...

Biology blurs line between sexes, behaviors

Biological sex is typically understood in binary terms: male and female. However, there are many examples of animals that are able to modify sex-typical biological and behavioral features and even change sex. A new study, ...

Fireflies shed light on the function of mitochondria

Tiny factories float inside our cells and provide them with almost all the energy they need: the mitochondria. Their effectiveness decreases when we get older, but also when we face many diseases such as diabetes, cancer ...
