Researchers discover a way to restore strength of cardiac muscles in aging fruit flies

Researchers may have discovered a way to turn back the clock on aging heart muscles in fruit flies, a development that could lead to new therapies for older humans with heart disease.

Dresden scientists identify newborn neurons in zebrafish

The zebrafish is a master of regeneration: If brain cells are lost due to injury or disease, it can simply reproduce them - contrary to humans where this only happens in the fetal stage. However, the zebrafish is evolutionarily related to humans and, thus, possesses the same brain cell types as humans.

Discovery of cellular 'hands' could have implications in the fields of cell, developmental biology

The protein, called syndecan-4, combines with fellow cell membrane proteins, called integrins, to form protruding 'hands' that sense the environment outside the cell.

Researchers study new immunogenic properties of already existing anti-cancer drugs

The world scientific community is waging a difficult and prolonged war on cancer. New research in the field of immunogenic cell death can extend the area of drugs application and ensure patients' protection from relapse after therapy.

Researchers move closer to identifying leukemic stem cells

Acute myeloid leukemia is the most common type of leukemia in adults. It is characterized by the pathological expansion of immature cells (myeloblasts) that invade the bone marrow and expand into the blood, affecting the production of the rest of the healthy cells.

Common plasticizer leads to fertility problems in roundworms

A new study published 9th January in PLOS Genetics by Mónica Colaiácovo of Harvard Medical School and colleagues reports that the most commonly used plasticizer, diethylhexyl phthalate, leads to fertility problems by causing an excess number of breaks in the DNA during egg production, and then interfering with the repair systems that fixes the breaks.

Grizzly bears' strategy could help prevent muscle atrophy in humans

Grizzly bears spend many months in hibernation, but their muscles do not suffer from the lack of movement. In the journal "Scientific Reports", a team led by Michael Gotthardt reports on how they manage to do this.

Study provides better understanding of mechanisms that limit cilia number in cells

One of the wonders of cell biology is its symmetry. Mammalian cells have one nucleus and one cell membrane, and most humans have 23 pairs of chromosomes.

A HSC surface marker plays key role in ontogeny of hematopoiesis

A group of researchers at Osaka University revealed that ESAM (Endothelial cell-selective adhesion molecule), a surface marker for hematopoietic stem cells (HSCs) and vascular endothelial cells (ECs), played an important role in the ontogeny of hematopoiesis in mice, particularly in the development of adult-type erythropoiesis.
