The study was published in Nature Cell Biology.

Possible new treatment strategy against progeria

Progeria is a very rare disease that affects about one in 18 million children and results in premature aging and death in adolescence from complications of cardiovascular disease. In a study on mice and human cells, researchers at Sweden's Karolinska Institute and IFOM, the FIRC Institute of Molecular Oncology in Italy, have identified how antisense oligonucleotide therapies could be used as a new possible treatment option for the disease. The results are published in the journal Nature Communications.

High-fat maternal diet can cause brain damage in the unborn child

A research team at MedUni Vienna's Center for Brain Research has found that high-fat maternal diets can cause life-long changes in the brains of the unborn offspring. When a pregnant woman consumes a diet high in polyunsaturated omega-6 fatty acids, her body produces an excess of endogenous cannabinoids (endocannabinoids), which overload the fetal system and impair the development of healthy brain networks. Such a mechanism seems relevant to pathologies such as ADHD, schizophrenia and anxiety disorders. It is unlikely that such damage can simply be reversed by a subsequent change of diet.

Quitting smoking could lead to major changes in gut bacteria

Quitting smoking leads to major changes in intestinal bacteria, according to new research. But just what the changes mean will need further investigation.

Researchers split the 'AtoM' in search of a treatment for rheumatoid arthritis

Arthritis is a common chronic disease in which joints become inflamed, leading to stiffness and pain that can often be debilitating. Rheumatoid arthritis (RA) is an autoimmune form of the disease, arising when immune cells attack the tissue that lines the joints. There is a need for new treatment options, as current therapies only alleviate symptoms or, at best, slow the disease. Now, in a study published in Nature Immunology, researchers at Osaka University have discovered a previously unknown type of RA-causing cell within arthritic joints that could someday be a target for new treatments.

Genetic alterations caused by cancer therapies identified

Living implies change. This is what happens to the cells of our bodies as we grow older: They accumulate genetic alterations, most of which are harmless. However, in some specific cases, these mutations can affect certain genes and can lead to the development of cancer. The source of these alterations can be exogenous (e.g., solar radiation, tobacco smoke or some toxic substance) or endogenous (e.g., errors in DNA processing).

Should scientists change the way they view (and study) same sex behavior in animals?

Over the years, scientists have recorded same-sex sexual behavior in more than 1,500 animal species, from snow geese to common toads. And for just as long evolutionary biologists studying these behaviors have grappled with what has come to be known as a "Darwinian paradox": How can these behaviors be so persistent when they offer no opportunity to produce offspring?

How gene expression noise shapes cell fate

Essential genes are often expressed with high variability during the development of cells. Scientists call this phenomenon "biological noise" and suspect that it is also decisive for the fate of cells, i.e. the developmental pathway a cell takes. Max Planck researcher Dominic GrĂ¼n now presents a method based on single-cell data to quantify this variability in gene expression. The advantage of the so-called VarID method is that the noise of gene expression can be measured across groups of very similar or related cell states. Thus, the Freiburg researcher hopes to gain a better understanding of the extent to which noise regulates development or is even necessary for the differentiation of cells.

Mantis shrimp vs. disco clams: Colorful sea creatures do more than dazzle

Nanomaterials in wastewater have toxic effects on crustaceans and fish

You may not always think about it when you do your laundry or flush the toilet, but whatever you eat, wear or apply on your skin ends up in wastewater and eventually reaches the environment. The use of nanoparticles in consumer products like textiles, foods and personal care products is increasing. What is so special about nanoparticles is their tiny size: One nanometer is one-billionth of a meter. The small size gives nanoparticles unique and novel properties compared to their bigger counterparts and may for example reach locations that bigger particles cannot reach.
