Scientists reveal detailed snapshot of bacterial microcompartment shells

For the first time, scientists have visualized the fine details of bacterial microcompartment shells - the organisms' submicroscopic nanoreactors, which are comprised completely of protein.

Could a blood test predict how cancer spreads in children?

Traditionally, we use biopsies to try to predict how cancer spreads. There are a number of molecular markers that are used, but biopsy is a limited approach. Now, the current trend is to use liquid biopsy, which is basically a blood sample.

Lungs of highly active older adults remain strong during physical activity

Highly active older adults experience no limitations in the lungs' capacity to exchange gases (lung-diffusing capacity) during physical activity, researchers have found. The study is published in the Journal of Applied Physiology.

Study reveals the body's systemic stem cell response to ACL injury

You might think stem cells only exist inside a fetus, but your adult body has a stockpile of stem cells, armed and ready to respond. These remarkable cells can develop into any other type of cell, like muscle or bone or nerve cells.

Research may lead to more accurate and reliable diagnostic test for autoimmune disease

In autoimmune diseases, the immune system wrongly identifies its "enemy", and produces antibodies that attack the patient's own cells.

Cornell researchers unravel E. coli bacteria's defense secret

By tagging a cell's proteins with fluorescent beacons, Cornell researchers have found out how E. coli bacteria defend themselves against antibiotics and other poisons. Probably not good news for the bacteria.

Hybrid filter offers low-cost option for purification of arsenic-contaminated water

The news story made a big splash: in January 2016 ETH researchers Professor Raffaele Mezzenga and his senior researcher Sreenath Bolisetty published a study in the journal Nature Nanotechnology about an innovative type of membrane developed in their laboratory.

Magnetic nanoparticle aggregates can induce death of cancer cells

An international team in which a UPM researcher is involved has shown that it is possible to mechanically destroy cancer cells by rotating magnetic nanoparticles attached to them in elongated aggregates.

Developing synthetic mediums for growing organoids

Organoids are bits of tissue grown in vitro, in a near-physiological 3D setting. The particularity consists in the fact that organoids retain features of the patient they are derived from, even when cultured outside of the human body. This is very different from what traditional, conventional cell culture has been able to do over the past 50 years or so.
