Research reveals how the brain balances pleasure and pain

As our brains take in information about the world and use it to steer our actions, two key principles guide our choices: seek pleasure and avoid pain.

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.

Ancestral-sequence reconstruction of FMO genes unveils structure of important enzyme

To disarm toxic substances, many organisms - including humans - possess enzymes called flavin-containing monooxygenases. Despite their importance, the structure of the enzymes has not been resolved, as the protein is too unstable to study in detail.

New, faster and cheaper method to uncover genetic variants in single cells

Researchers led by the European Molecular Biology Laboratory in Heidelberg and the Center for Bioinformatics at Saarland University in Saarbrücken, Germany, have developed a cheaper and faster method to check for genetic differences in individual cells, which outperforms existing techniques with respect to the information received.

Researchers develop powerful computer algorithm for large-scale genomic analysis

Haplotypes are a set of genetic variations that, located side by side on the same chromosome, are transmitted in a single group to the next generation. Their examination makes it possible to understand the heritability of certain complex traits, such as the risk of developing a disease.

Study reveals new role for a triple-negative breast cancer target

Unlike almost every other organ, the mammary gland does not develop until after birth. And it's unusually dynamic, shape-shifting during menstrual cycles, puberty, pregnancy, and lactation.

Different mutations in a single gene can have myriad effects on a person's health

Mount Sinai researchers have found that different mutations in a single gene can have myriad effects on a person's health, suggesting that gene therapies may need to do more than just replenish the missing or dysfunctional protein the gene is supposed to encode, according to a study published in Nature Genetics in November.
