Water-Soluble Warped Nanographene

Synthesis of a water-soluble warped nanographene and its application for photo-induced cell death

13-Feb-2018

Graphene and its nano-sized little sibling, nanographene, are well known for their remarkable photoelectronic properties. However, biomedical applications are hampered by the insolubility of the materials, especially in water. A Japanese team of scientists has now introduced substituted “warped ...

Surprise finding points to DNA's role in shaping cells

12-Feb-2018

As a basic unit of life, the cell is one of the most carefully studied components of all living organisms. Yet details on basic processes such as how cells are shaped have remained a mystery. Working at the intersection of biology and physics, scientists at the University of California San Diego ...

New mouse model makes stem cells light up green

Random find opens up new perspectives

06-Feb-2018

Multipotent stromal cells have long been a hot topic in medical research. Scientists at the University of Bonn have now found a way to specifically mark these stem cells. This makes it possible to analyze their distribution pattern and their function in living organisms. In order to examine a ...

Parasite mimics human proteins to provide 'ready meals' from the gut

31-Jan-2018

Giardia parasites - responsible for one of the world's most common gastric diseases - are able to mimic human cell functions to break apart cells in the gut and feed off them, new research has shown. A team at the University of East Anglia (UEA) has been investigating the secret behind the ...

DNA study casts light on century-old mystery of how cells divide

22-Jan-2018

Scientists have solved a longstanding puzzle of how cells are able to tightly package DNA to enable healthy cell division. Their findings shed light on how single cells can compact DNA 10,000-fold to partition it between two identical cells - a process that is essential for growth, repair and ...

How do we taste sugar, bacon and coffee?

A new chemical pathway that helps the brain detect sweet, savory and bitter flavors

11-Jan-2018

How do we taste the sugary richness of candy, or the bitter undertones of coffee? What about the savory flavors of smoked and cured meats? Until now, many scientists believed that a single protein -- TRPM5 -- acted as a gatekeeper for tasting these delectable foods. Remove TRPM5 from a person's ...

(Re)-acquiring the potential to become everything

20-Dec-2017

A new study identifies a specific population of pluripotent embryonic stem cells that can reprogram to totipotent-like cells in culture. Moreover, the scientists of Helmholtz Zentrum München and Ludwig-Maximilians-Universität München (LMU) have identified bottlenecks and drivers of this ...

Visible signals from brain and heart

New sensor measures calcium concentrations deep inside tissue

01-Dec-2017

Key processes in the body are controlled by the concentration of calcium in and around cells. A team from the Technical University of Munich (TUM) and the Helmholtz Zentrum München have developed the first sensor molecule that is able to visualize calcium in living animals with the help of a ...

New tissue-engineered blood vessel replacements one step closer to human trials

03-Nov-2017

Researchers at the University of Minnesota have created a new lab-grown blood vessel replacement that is composed completely of biological materials, but surprisingly doesn't contain any living cells at implantation. The vessel, that could be used as an "off the shelf" graft for kidney dialysis ...
