Clusters of protein linked to cancer warp cell membranes

Supercomputer simulations have shown that clusters of a protein linked to cancer warp cell membranes, according to scientists at The University of Texas Health Science Center at Houston (UTHealth) Medical School.

Scientists advise caution with regard to artificial insemination method

Mitochondria are cell organelles located within animal and human cells. They produce energy for the organism, possess their own genetic material - mitochondrial DNA (mtDNA) - and are transmitted exclusively by the mother. Depending on their activity and tasks, different numbers of mitochondria are present in a cell - usually a few hundred to a thousand per body cell.

GENETICS and G3: Genes|Genomes|Genetics publish special collection on genetics of immunity

Immunity is what stops you dying from a common cold or a tiny pinprick. Differences in resistance or tolerance to disease influence who catches the bug that's going around the office, or which species succumb to the deadly fungus devastating frogs around the world.

Cannabis use affects size and shape of sperm in young men

Young men who use cannabis may be putting their fertility at risk by inadvertently affecting the size and shape of their sperm according to research published today (Thursday 5 June 2014).

Novel incubator microscope ideally suited for time-lapse examination

Biologists and doctors rely heavily on incubators and microscopes. Now the Fraunhofer Institute for Biomedical Engineering IBMT has come up with a novel solution that combines the functions of both these tools in a compact and extremely small-scale system.

Female mice deprived of dietary zinc before conception experience fertility problems

Female mice deprived of dietary zinc for a relatively short time before conception experienced fertility and pregnancy problems and had smaller, less-developed fetuses than mice that ingested zinc during the same times, according to researchers in Penn State's College of Agricultural Sciences.

Researchers study why male babies generally have worse outcomes than females

Sexual inequality between boys and girls starts as early as in the mother's womb - but how and why this occurs could be a key to preventing higher rates of preterm birth, stillbirth and neonatal death among boys.

Separating sperm and eggs from somatic cells preserves genetic building blocks

We have hundreds of types of cells in our bodies - everything from red blood cells to hair follicles to neurons. But why can't most of them create offspring for us?

Men with sperm abnormalities at increased risk of dying sooner, study finds

Men who are infertile because of defects in their semen appear to be at increased risk of dying sooner than men with normal semen, according to a study led by a researcher at the Stanford University School of Medicine.

Study reveals how human genome is protected from inadvertent import of viral RNA into cell

Scientists of the Max F. Perutz Laboratories of the University of Vienna and the Medical University of Vienna, together with colleagues of the ETH Zurich, have now shown how double stranded RNA, such as viral genetic information, is prevented from entering the nucleus of a cell.

Vivere-Winter Park recognizes 25th Annual National Infertility Awareness Week

Infertility is a disease affecting more than 7 million people across the U.S., according to the National Survey of Family Growth. That number represents 12 percent of women of childbearing age or one in eight couples.

Human testes respond differently to endocrine disrupting chemicals

Human and rat testes respond differently to endocrine disrupting chemicals such as BPA in two thirds of all cases, according to a recent review. As human safety levels are extrapolated from rodent data, the study could lead to a re-evaluation of the acceptable daily intake for many endocrine disruptors.
