Researchers find signaling pathway in cells that plays key role in development of fatty liver disease

Morbid obesity affects the liver: Almost one-third of all adults suffer from chronic fatty liver disease, which can lead to infections and even trigger cancer. Researchers at the University Children's Hospital Zurich and the University of Zurich have now found a signaling pathway in cells that play an important role in the development of fatty liver disease.

Long non-coding RNAs could represent novel male infertility drug targets

Scientists have found distinctive portions of genetic material--known as lncRNAs--that help sperm develop. Male mice lacking a particular lncRNA have low sperm count, suggesting lncRNAs could represent novel infertility drug targets.

Fruit flies' pheromones reveal sexual attractiveness of females

Life as a fruit fly seems pretty simple: Hatch, grow, eat some fruit, find a mate, produce hundreds of tiny offspring and die -- all in a month or so.

Ants can adapt their chemical profile over short evolutionary periods, say biologists

The bodies of ants and other insects are covered with a thin, wax-like layer that protects them from desiccation and enables them to exchange information, in social insects, for instance, to differentiate between enemies and nestmates.

Effects of declining sperm counts on fertility, mortality and disease patterns in geographical areas: Study

There is a lack of definitive data on the actual trends of decline in sperm counts according to researchers despite it being a known fact. Researchers in a new study looked at a large population to find the exact data regarding this scenario and its effects on the society. They looked at the effects of fertility and geographical distribution on the sperm concentration as well as total sperm counts.

Multiple cycles with IVF lead to higher chances of pregnancy success

Research has shown that women who undergo multiple cycles of IVF (In Vitro Fertilization) are more likely to have a baby. The study published in the Medical Journal of Australia reports the cumulative live birth rates after complete ovarian stimulation cycles. The study looked at chances of having a baby successfully after several rounds of IVF or other types of assisted reproduction techniques.

Study provides insights into intergenerational inheritance of epigenetic information

We are more than the sum of our genes. Epigenetic mechanisms modulated by environmental cues such as diet, disease or our lifestyle take a major role in regulating the DNA by switching genes on and off.
