Communication breakdowns between care facilities can pave the way for outbreaks of infection, according to research on the spread of an extensively drug-resistant bacterium.
When it comes to male reproductive fertility, timing is everything. Now scientists are finding new details on how disruption of this timing may contribute to male infertility or congenital illness. Researchers are identifying the key molecular and genetic switch that activates production of healthy male sperm — but only when the time is right.
Tapping into the public’s passion for the ocean could be the key to reducing the threats to it posed by plastic pollution.
It had already been known that the enzyme known as phosphatidic acid phosphatase plays a crucial role in regulating the amount of fat in the human body. Controlling it is therefore of interest in the fight against obesity. But scientists have now found that getting rid of the enzyme entirely can increase the risk of cancer, inflammation and other ills.
An international research team has shown for the first time that carbohydrates on the surface of malaria parasites play a critical role in malaria’s ability to infect mosquito and human hosts. The discovery also suggests steps that may improve the only malaria vaccine approved to protect people against Plasmodium falciparum malaria — the most deadly form of the disease.
A method to help determine whether certain hard-to-study mutations in the human genome, called short tandem repeats or microsatellites, are likely to be involved in harmful conditions has been created by a team of researchers.
Body fat distribution in the trunk is more important than body weight when it comes to cancer risk in postmenopausal women, according to a new study.
Patients suffering from Alzheimer’s and Parkinson’s disease harbor significantly higher levels of zinc and iron in their brains than healthy patients. Those with pancreatic cancer have an unusually high amount of a specific zinc transporter. So, controlling those levels could be an effective plan of attack against these diseases and others, say researchers.
The contact areas between nerve cells are called synapses. What happens there lies at the heart of communication between nerve cells. Communication starts with the release of chemical messengers known as neurotransmitters at these synapses. Neurotransmitter-containing synaptic vesicles are involved in this release process, and these vesicles fuse with the cell membrane. This fusion occurs at a specific location within the synapse rather than just anywhere at random. Scientists have succeeded in identifying the molecule, which determines where in the synaptic gap neurotransmitters are released.
Research has demonstrated the potential of a protein to treat or prevent metabolic diseases including obesity and diabetes.
