Marine plankton samples can help understand the link between ocean pollution and chronic illnesses

Using samples from an almost century-old, ongoing survey of marine plankton, researchers at University of California San Diego School of Medicine suggest that rising levels of manmade chemicals found in parts of the world's oceans might be used to monitor the impact of human activity on ecosystem health, and may one day be used to study the connections between ocean pollution and land-based rates of childhood and adult chronic illnesses.

Investigating the molecular mechanisms that govern cilia force sensing

Although the human body is superficially symmetric along the left–right axis, most internal organs, including the heart, lungs, liver, stomach, and brain, have noteworthy left–right asymmetries in their structure and placement.

Novel insights into the elongation dynamics of eukaryotic cells

The proper functioning of numerous proteins generated in cells by ribosomes is essential for life. This diversified variety of proteins, called proteome, is sustained by the ribosomes’ vigorous translation elongation of amino acid sequences.

Elucidation of mitochondrial membrane pore formation

Human metabolism depends on mitochondria, which are regarded as the power plants of cells. But since 40% of the proteins in the mitochondria are dysfunctional and are linked to human diseases, mitochondria also play a significant role in medical research.

Researchers expand the known defensive abilities of CRISPR–Cas systems

Viruses can infect bacteria and archaea, just as they can humans. These microbes have evolved their own immune defense mechanisms to combat their pathogens. Bacterial defenses, like CRISPR-Cas systems, contain a variety of proteins and functions that aid bacteria in protecting themselves from foreign intruders.

The detrimental effects of alcohol consumption during pregnancy

For the first time, researchers at the University of Helsinki in Finland examined the effects of prenatal alcohol exposure on the epigenome and gene function of the placenta. The epigenome is a molecular coating on a DNA strand that controls how genes are expressed.

Improving cancer immunotherapies with bioengineered synthetic gene circuits

In two distinct studies, scientists show how synthetic biology can be used to address a challenging problem in cancer immunotherapy: the way immunotherapy-related approaches focused on the short-term killing of tumor cells could fail to eradicate tumors because tumor growth occurs on longer timescales.
