Finding Chemicals inside a Cell

Chemical and topographical single-cell imaging at nanoscale resolution by near-field desorption mass spectrometry

08-Feb-2019

How are chemicals distributed in a cell? Chinese scientists have developed a combined mass spectrometry and biological imaging device that enables direct, label-free detection, and high-resolution mapping of chemicals inside a biological cell. As demonstrated in their publication in the journal ...

Bifacial Stem Cells Produce Wood and Bast

One of the most important growth processes on Earth studied

24-Jan-2019

So-called bifacial stem cells are responsible for one of the most critical growth processes on Earth – the formation of wood. By alternately developing into wood and bast cells, these stem cells are thus starting points for forming wood as well as generating plant bast fibres. A team of ...

Novel materials convert visible into infrared light

Penetrate of living tissue and other materials without damage by high-intensity light exposure

18-Jan-2019

Columbia University scientists, in collaboration with researchers from Harvard, have succeeded in developing a chemical process to convert visible light into infrared energy, allowing innocuous radiation to penetrate living tissue and other materials without the damage caused by high-intensity ...

New fuel-delivery route for cells identified

Findings shed light on chronic diseases, aging

10-Jan-2019

Scientists at Washington University School of Medicine in St. Louis have identified a previously unknown route for cellular fuel delivery, a finding that could shed light on the process of aging and the chronic diseases that often accompany it. With age, cells gradually lose their ability to take ...

Progress in Super-Resolution Microscopy

20-Dec-2018

Does expansion microscopy deliver true-to-life images of cellular structures? That was not sure yet. A new publication shows for the first time that the method actually works reliably. Immersing deeper and deeper into cells with the microscope. Imaging the nucleus and other structures more and ...

A new molecular player involved in T cell activation

13-Dec-2018

When bacteria or viruses enter the body, proteins on their surfaces are recognized and processed to activate T cells, white blood cells with critical roles in fighting infections. During T-cell activation, a molecular complex known as the microtubule-organizing center (MTOC) moves to a central ...

New Ways to Look at Protein-RNA Networks

10-Dec-2018

For their vital tasks, all RNA molecules in our cells require proteins as binding partners. Scientists at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and colleagues from the European Molecular Biology Laboratory (EMBL) have developed the first method with which they ...

Making an eye for you

The underlying mechanisms of 3D tissue formation

27-Nov-2018

If you want to build an organ, such as for transplant, you need to think in 3D. Using stem cells, scientists for some time have been able to grow parts of organs in the lab, but that is a far cry from constructing an actual, fully-formed, functioning, three-dimensional organ. For students of ...

Solar panels for yeast cell biofactories

19-Nov-2018

Genetically engineered microbes such as bacteria and yeasts have long been used as living factories to produce drugs and fine chemicals. More recently, researchers have started to combine bacteria with semiconductor technology that, similar to solar panels on the roof of a house, harvests energy ...

Poxvirus hijacks cell movement to spread infection

13-Nov-2018

Vaccinia virus, a poxvirus closely related to smallpox and monkeypox, tricks cells it has infected into activating their own cell movement mechanism to rapidly spread the virus in cells and mice, according to a new UCL-led study. The findings explain how the virus mimics infected cells' own ...
