Study suggests dietary intake of flavan-3-ols could help prevent obesity

In cold conditions, brown adipose tissue (BAT) or brown fat generates heat to keep the body warm. Compared with white adipose tissue, BAT has more mitochondria-;subcellular organelles associated with energy production-;which allows it to burn calories and produce heat by activating the mitochondrial uncoupling protein 1 (Ucp-1).

Scientists test the accuracy of enzymes that copy DNA under weightlessness

Researchers at Queen’s University boarded a modified Falcon 20 aircraft at Ottawa airport on May 22nd, 2019 as part of a scheduled “vomit comet” flight. In this mode of flight, the plane repeatedly climbs in a steep parabola to 8 km, alternating with a freefall descent.

Study shows why disruption of the body clock leads to inflammatory diseases

New research from RCSI has demonstrated the significant role that an irregular body clock plays in driving inflammation in the body's immune cells, with implications for the most serious and prevalent diseases in humans.

Cancer cells disarm immune cells by hijacking mitochondria, says research

Researchers utilized the power of nanotechnology to identify a novel means that cancer cells use to disarm their would-be cellular attackers.

Diet has a much stronger impact on the inner workings of cells than drugs

A study comparing the impact of diet versus drugs on the inner workings of our cells has found nutrition has a much stronger impact.

Green tea catechins extend the lifespan of C. elegans

Aging-US published "Green tea catechins EGCG and ECG enhance the fitness and lifespan of Caenorhabditis elegans by complex I inhibition" which reported that green tea catechins are associated with a delay in aging.

New program can help to correctly interpret the genetic code of newly sequenced organisms

Yekaterina "Kate" Shulgina was a first year student in the Graduate School of Arts and Sciences, looking for a short computational biology project so she could check the requirement off her program in systems biology. She wondered how genetic code, once thought to be universal, could evolve and change.

Researchers propose novel model for mitochondrial nucleoid self-assembly

Mitochondria, the powerhouse of mammalian cells, also perform vital roles in cell signaling, cell metabolism, and apoptosis.

'Rewiring' the mitochondria in macrophages can resolve inflammatory reactions

New data from a research team at Friedrich-Alexander-Universität Erlangen-Nürnberg shows how inflammatory reactions can be resolved by changes to the metabolism of macrophages.

Discovery of long-lived mitochondrial proteins reveals increased stability of the electron transport chain

Mitochondria are known as the powerhouses of the cell, generating the energy that's needed to fuel the functions that our cells carry out.

Study reveals how glycogen is linked to thermogenesis in fat cells

Humans carry around with them, often abundantly so, at least two kinds of fat tissue: white and brown. White fat cells are essentially inert containers for energy stored in the form of a single large, oily droplet.

Mitochondrial inner membrane fusion protein acts as a molecular chaperone

Cells contain numerous functional “micro-organs” known as organelles. Mitochondria, the “power plant” of the cell, are the energy-producing organelles.

Mitochondria of diabetic patients can't keep track of time, study finds

Almost all cells regulate their biological processes over a 24-hour period, otherwise called a cell's circadian rhythm. To do so, cells use a biological clock that cycles different genes on and off throughout the day and night.

Metabolic restoration could provide natural protection against HIV

The human immunodeficiency virus (HIV-1) particularly attacks CD4 lymphocytes, a type of white blood cell considered to be the conductor of the immune system.

Researchers uncover how killer T cells repeatedly reload their toxic weapons to keep on killing

Cambridge researchers have discovered how T cells – an important component of our immune system – are able keep on killing as they hunt down and kill cancer cells, repeatedly reloading their toxic weapons.

Infection with measles virus activates two different immune responses

Researchers from The University of Tokyo Institute of Industrial Science have found that infection with the measles virus activates not one but two different branches of the innate immune system.

Newly developed method helps refine the "Out of Africa" scenario

Researchers from Estonia and Italy developed an innovative method by combining neural networks and statistics. Using this newly developed method, they refined the "Out of Africa" scenario. The researchers claimed that the African dynamics around the time of the Out of Africa expansion are more complex than previously thought.

Loss of mitochondrial respiration alters mechanical properties of the cartilage

A group of researchers headed by Professor Dr Bent Brachvogel, Head of Experimental Neonatology at the Faculty of Medicine and University Hospital Cologne, have identified regulatory mechanisms of tissue organization which were earlier unknown.

Experts describe structure of protein complex vital for proper cell function

Mitochondrial diseases exhibit different symptoms like muscle weakness, severe fatigue, even blindness. Most genetic diseases are the result of mitochondrial defects.

Microglial cells join together to break down toxic proteins more quickly

To break down toxic proteins more quickly, immune cells in the brain can join together to form networks when needed. This is shown by a joint study of the University of Bonn, the German Center for Neurodegenerative Diseases, and the Institut François Jacob in France.
