Throwing molecular wrench into gene control machine leads to ‘melting away’ of leukemia

Cancer researchers today announced they have developed a way of sidelining one of the most dangerous “bad actors” in leukemia. Their approach depends on throwing a molecular wrench into the gears of an important machine that sets genes into motion, enabling cancer cells to proliferate.

‘Brain-on-a-chip’ tests effects of biological and chemical agents, develop countermeasures

Lawrence Livermore National Laboratory (LLNL) scientists and engineers have developed a “brain-on-a-chip” device aimed at testing and predicting the effects of biological and chemical agents, disease or pharmaceutical drugs on the brain over time without the need

Proteome of the human heart mapped for the first time

A healthy heart beats about two billion times during a lifetime, thanks to the interplay of more than 10,000 proteins. Researchers from the Max Planck Institute of Biochemistry (MPIB) and the German Heart Centre at the Technical University of Munich (TUM) have now determined which and how many individual proteins are present in each type of cell in the heart. They have now compiled the first atlas of the healthy human heart, known as the cardiac proteome. The atlas will make it easier to identify differences between healthy and diseased hearts in future.

Blood testing via sound waves may replace some tissue biopsies

Scientists from MIT and other institutions have developed a microfluidic device that uses sound waves to isolate cellular packets called exosomes from blood samples, which could be used to diagnose diseases such as cancer or fetal abnormalities.

Bioengineered Lungs With Intact Blood Vessels Just Came One Step Closer to Reality

A group of researchers at Columbia University’s School of Engineering and Applied Science have successfully developed the first functional vascularised lung scaffold, and it could dramatically change how lung disease is treated.

Nanomachines that drill into cancer cells killing them in just 60 seconds developed by scientists

Nanomachines which can drill into cancer cells, killing them in just 60 seconds, have been developed by scientists. The tiny spinning molecules are driven by light, and spin so quickly that they can burrow their way through cell linings when activated. In one test conducted at Durham University the nanomachines

Breakthrough device heals organs with a single touch

Researchers at The Ohio State University Wexner Medical Center and Ohio State’s College of Engineering have developed a new technology, Tissue Nanotransfection (TNT), that can generate any cell type of interest for treatment within the patient’s own body. This technology may be used to repair injured tissue or restore function of aging tissue, including organs, blood vessels and nerve cells.
