Discovery reveals new type of brain cell sensitive to distance and direction of objects

The existence of GPS-like brain cells, which can store maps of the places we've been, like our kitchen or holiday destination, was already widely known, but this discovery shows there is also a type of brain cell sensitive to the distance and direction of objects that can store their locations on these maps.

Study highlights the far-reaching effects of mutagenic compounds on human health

In order to survive, flourish and successfully reproduce, organisms rely on a high degree of genetic stability. Mutagenic agents, which can threaten the integrity of the genetic code by causing mutations in DNA, pose a serious risk to human health.

Stem cells in the brain divide over months to create new nerve cells

For the first time, scientists at the University of Zurich have been able to observe stem cells in the adult mouse brain that divide over the course of several months to create new nerve cells. The study shows that brain stem cells are active over a long period, and thus provides new insights for stem cell research.

The weak spot of colon cancer stem cells

Colon cancer stem cells have one weak spot: the enzyme Mll1. An MDC team led by Walter Birchmeier has now shown in Nature Communications that blocking this protein prevents the development of new tumors in the body.

Novel microcopy methods used to study tiny traction forces during T-cell activation

Highly complicated processes constantly take place in our body to keep pathogens in check: The T-cells of our immune system are busy searching for antigens - suspicious molecules that fit exactly into certain receptors of the T-cells like a key into a lock.

Stem cell engineering used to identify gene signaling pathway linked to schizophrenia

Using human-induced pluripotent stem cells engineered from a single family's blood samples, a gene signaling pathway linked to a higher risk for developing schizophrenia was discovered by scientists at The University of Texas Health Science Center at Houston.

New understanding of physical properties of chromatin may show how genome is encoded and decoded

University of Alberta researchers have found an answer to a fundamental question in genomic biology that has eluded scientists since the discovery of DNA: Within the nucleus of our cells, is the complex package of DNA and proteins called chromatin a solid or a liquid?

A protein plays key role in the spread of stress signals among liver cells

A key protein in the communication channels between cells can allow a stress response in one liver cell to spread to neighboring liver cells in mice, causing otherwise healthy cells to become dysfunctional, according to new research co-led by Harvard T.H. Chan School of Public Health and Sheba Medical Center in Israel.

New microscope could allow surgeons to inspect tumor margins within minutes

When surgeons remove cancer, one of the first questions is, "Did they get it all?" Researchers from Rice University and the University of Texas MD Anderson Cancer Center have created a new microscope that can quickly and inexpensively image large tissue sections, potentially during surgery, to find the answer.

Cell atlas helps better understand the biology of tropical disease parasite

The first cell atlas of an important life stage of Schistosoma mansoni, a parasitic worm that poses a risk to hundreds of millions of people each year, has been developed by researchers at the Wellcome Sanger Institute and their collaborators.

Pig stem cells offer a new way to grow human organs for transplantation

In a new paper published in Stem Cell Reports, Bhanu Telugu and co-inventor Chi-Hun Park of the University of Maryland (UMD) Department of Animal and Avian Sciences show for the first time that newly established stem cells from pigs, when injected into embryos, contributed to the development of only the organ of interest (the embryonic gut and liver), laying the groundwork for stem cell therapeutics and organ transplantation.

Discovery of protein function could be important for future chemotherapy treatment

Chemotherapy attacks all cells in our body and not just cancer cells, which is why patients undergoing the treatment often experience side effects such as physical weakness, hair loss and nausea.

Research suggests a novel mechanism for modulating emotional behavior

Research led by Si-Qiong June Liu, MD, PhD, Professor of Cell Biology and Anatomy at LSU Health New Orleans School of Medicine, discovered a surprising reciprocal interaction between chemicals in the brain resulting in accelerated loss of molecules that regulate brain cell communication.

Researchers discover cells responsible for resistance to T-ALL treatment

T-cell acute lymphoblastic leukemia (T-ALL) is a cancer of the blood that affects mainly children, but also less frequently adults. In adults, although the response to treatment might be initially positive, relapses are common and have a poor prognosis.
