Live-cell imaging provides new insights into dynamic structure of mitochondria

As power plants and energy stores, mitochondria are essential components of almost all cells in plants, fungi and animals. Until now, it has been assumed that these functions underlie a static structure of mitochondrial membranes.

Fruit flies have a new defense strategy to deal with oxidative stress

Oxidative stress affects all living organisms, and the damage it causes is believed to play a part in cancer, diabetes, Alzheimer's disease and a number of other health conditions.

Detailed maps of breast cancer reveal how genetic changes shape the tumor landscape

Scientists have created one of the most detailed maps of breast cancer ever achieved, revealing how genetic changes shape the physical tumor landscape, according to research funded by Cancer Research UK and published in Nature Cancer today (Monday).

New technology enables scientists to analyze behavior of cancer cells in lab-grown tumors

New technology developed at UCL is, for the first time, enabling cancer scientists to analyze the individual behavior of millions of different cells living inside lab-grown tumors - a breakthrough which could lead to new personalised cancer treatments.

Oxidative stress induces sleep in fruit flies, research shows

Sleep-deprived fruit flies helped reveal what induces sleep. University of Oxford researchers Anissa Kempf, Gero Miesenböck, and colleagues reveal that fruit fly sleep is driven by oxidative stress, the imbalance of free radicals and antioxidants in the body. Kempf

Dormancy emerges as a natural evolutionary response to over-predation, study finds

Why do predators sometimes lay dormant eggs -- eggs which are hardy, but take a long time to hatch, and are expensive to produce?

New biological tool can detect and debug faulty genetic circuits

Every cell in our body has a computer-like control system that sends biological signals through thousands of circuits to monitor the cell's needs and regulate its responses.

Unique reproductive trait for seagrass revealed

Seagrasses have long been known as some of Earth's most remarkable organisms--descendants of flowering land plants that have re-colonized the ocean by developing traits that allow them to grow, pollinate, and release seeded fruits while fully immersed in salty seawater.

Conspicuously large nerve cells have unique functions essential for survival

The brains of most fish and amphibian species contain a pair of conspicuously large nerve cells. These are the largest cells found in any animal brain.

UIC researchers discover unique organ-specific signatures for endothelial cells

Researchers from the University of Illinois at Chicago have discovered that endothelial cells -; those that create the inner lining of blood vessels -; have unique genetic signatures based on their location in the body.

New study describes inflammatory reaction in lab-developed human astrocytes

Astrocytes are neural cells with many important functions in the nervous system. The inflammation of these cells occurs in brain infections and neurodegenerative disorders, a process called astrogliosis.

Study explains how certain mutations can shorten biological clock timing

A new study of molecular interactions central to the functioning of biological clocks explains how certain mutations can shorten clock timing, making some people extreme "morning larks" because their internal clocks operate on a 20-hour cycle instead of being synchronized with the 24-hour cycle of day and night.

New mathematical technique describes the behavior of cellular enzymes

Everything a cell does, from dividing in two to migrating to a different part of the body, is controlled by enzymes that chemically modify other proteins in the cell.
