Research reveals factors at play in genetic incompatibility of different species

Most evolutionary biologists distinguish one species from another based on reproductivity: members of different species either won't or can't mate with one another, or, if they do, the resulting offspring are often sterile, unviable, or suffer some other sort of reduced fitness.

Researchers shed new light on the body's largest cell receptor

A giant toadstool that swallow up vitamins and nutrients. This is how the receptor, which e.g. absorbs B12 vitamin, looks. For the first time, researchers have an insight into a biology which has survived millions of years.

Researchers develop new method of analysis to map cellular locations of proteins

Researchers at Karolinska Institutet and SciLifeLab have developed a new method of analysis that maps the location of proteins in the cell. The information has been compiled in a database that is accessible to researchers around the world.

Fruit fly study sheds light on the evolution of metabolism

Diet choice of animal species is highly variable. Some are specialists feeding only on one food source, such as a sugar-rich fruit or protein-rich meat. Other species, like humans, are generalists that can feed on different kinds of food sources.

Senescent cells in the brain shown to cause obesity-related anxiety

Researchers have shown that obesity increases the level of semi-dormant senescent cells in the brain, which give rise to anxiety-like behaviors.

Researchers reveal cause of possible genetic problems in mitochondria

A group of researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine has revealed the importance of eliminating any excess of defective products that might have accumulated in the mitochondria, as its presence generates mitochondrial instability and information loss on the mitochondrial genome.

Researchers identify genes that drive male-female brain differences, trigger initiation of puberty

Researchers have identified a group of genes that induces differences in the developing brains of male and female roundworms and triggers the initiation of puberty, a genetic pathway that may have the same function in controlling the timing of sual maturation in humans.

Scientists cast new light on function of long-mysterious PCSK9 mutation

High levels of low-density lipoproteins, parcels of lipids and protein that carry cholesterol, are a leading risk factor for heart disease. Many cholesterol medications lower LDL, some of them by targeting the protein PCSK9. In the January issue of the Journal of Lipid Research, scientists at the University of California, San Francisco, report on an investigation into why experiments on PCSK9 give different results in a test tube and in liver cells.

Study provides new insights into how genes are activated

In a study in Nature, researchers at Karolinska Institutet present a new method for analyzing how instructions in the genome control how our genes are activated in individual cells.

Hyperactive immune system implicated in aging brain disorders

In a study of fruit flies, NIH scientists suggested that the body's immune system may play a critical role in the damage caused by aging brain disorders. The results are based on experiments in which the researchers altered the activity of Cdk5, a gene that preclinical studies have suggested is important for early brain development and may be involved in neurodegenerative diseases, such as ALS, Alzheimer's and Parkinson's disease.

Study uncovers how tumors backfire on neoadjuvant chemotherapy

Some patients with breast cancer receive chemotherapy before the tumor is removed with surgery. This approach, called 'neoadjuvant' therapy, helps to reduce the size of the tumor to facilitate breast-conserving surgery, and can even eradicate the tumor, leaving few or no cancerous cells for the surgeon to remove.

Salk scientists show how brain cells filter information in groups

When we perceive the world around us, certain objects appear to be more noticeable than others, depending on what we do. For example, when we view a forest-covered mountain from a distance, the forest looks like a large green carpet. But as we get closer, we start noticing the individual trees, and the forest fades to the background.

Researchers compile atlas of genetic influences on osteoporosis

A ground-breaking new study led by researchers from the Lady Davis Institute (LDI) at the Jewish General Hospital (JGH) has succeeded in compiling an atlas of genetic factors associated with estimated bone mineral density (BMD), one of the most clinically relevant factors in diagnosing osteoporosis.

New research could help restore youthful characteristics

If only we could keep our bodies young, healthy and energetic, even as we attain the wisdom of our years. New research at the Weizmann Institute of Science suggests this dream could be at least partly obtainable in the future.

New insights on cellular death mechanisms caused by the loss of neuronal cells and astrocytes

The blood circulation to neurons is affected due to Ischemic, hemorrhagic stroke and subarachnoid hemorrhage stimulation the activation of pathophysiological responses i.e. mitochondrial death pathways, protein misfolding, apoptosis, pyroptosis, necrosis, autophagy, mitophagy, ferritinophagy, excitotoxicity, free radicals release, and inflammation.

Sound can affect perception of touch in mice

Our eyes, ears and skin are responsible for different senses. Moreover, our brain assigns these senses to different regions: the visual cortex, auditory cortex and somatosensory cortex. However, it is clear that there are anatomical connections between these different cortices such that brain activation to one sense can influence brain activation to another
