Ribosomes spontaneously change their form during protein production

Ribosomes, the construction sites for proteins, are far more complex than previously assumed. During the production of proteins they constantly and spontaneously change their form. This performance of eukaryotic ribosomes has now been demonstrated for the first time by scientists at Charité - Universitätsmedizin Berlin, the Max-Planck-Institut für Molekulare Genetik in Berlin, and Cornell University in New York, with the aid of special electron microscopic and biophysical methods.

Breakthrough in loading gold nanorods into cells could lead to new cancer treatment

Rice University chemists have found a way to load more than 2 million tiny gold particles called nanorods into a single cancer cell. The breakthrough could speed development of cancer treatments that would use nanorods like tiny heating elements to cook tumors from the inside.

New technique helps identify how RNA molecules control gene expression

A new technique developed by researchers at the Stanford University School of Medicine allows researchers to identify the exact DNA sequences and locations bound by regulatory RNAs. This information is necessary to understand how the recently identified RNA molecules control the expression of neighboring and distant genes.

New floating microscopic device for researchers to study wide range of cellular processes

It's a bit of a challenge. But, imagine a microscopic jet vacuum cleaner, the size of a pen nib that hovers over cell surfaces without ever touching them. Then imagine that the soap in the cleaning solution is replaced with various molecules that can be selectively delivered to the cells. This gives you a sense of a new device that researchers believe will serve as a powerful tool to study the behaviour of living cells and a range of crucial cellular processes, from cancer cell formation to how neurons align themselves in the developing brain.

Study examines effects of carbon nanoparticles on living cells

A study by researchers from the schools of science and medicine at Indiana University-Purdue University Indianapolis examines the effects of carbon nanoparticles (CNPs) on living cells. This work is among the first to study concentrations of these tiny particles that are low enough to mimic the actual exposure of an ordinary individual.

Researchers combine 3-D printing technology and multiphoton polymerization to develop artificial blood vessels

Researchers have been working at growing tissue and organs in the laboratory for a long time. These days, tissue engineering enables us to build up artificial tissue, although science still hasn't been successful with larger organs. Now, researchers at Fraunhofer are applying new techniques and materials to come up with artificial blood vessels in their BioRap project that will be able to supply artificial tissue and maybe even complex organs in future.

Efficient, economical molecule could speed evaluation of some anti-cancer treatments

Researchers from Boston College have developed a new class of small molecule receptors capable of detecting a lipid molecule that reveals the telltale signs of cellular death, particularly cancer cells targeted by anti-cancer drugs, the team reports in the current electronic edition of the Journal of the American Chemical Society.

Researchers help explain elusive mechanics of complex cell transport system

Every cell in the human body contains a complex system to transport essential cargoes such as proteins and membrane vesicles, from point A to point B. These tiny molecular motor proteins move at blistering speeds on miniature railways carrying components of the cell to their proper destinations.

Researchers pave the way for functional analysis of non-protein-coding genes

When investigating cancer cells, researchers discovered numerous peculiarities: Particular RNA molecules are present in large numbers, particular genes are overactive. Do these characteristics have a relation to cancer? Do they promote cell growth? Do they inactivate growth brakes or are they just a whim of nature?

Scientists identify critical protein responsible for Ebola virus infection

In separate papers published online in Nature, two research teams report identifying a critical protein that Ebola virus exploits to cause deadly infections. The protein target is an essential element through which the virus enters living cells to cause disease.

Two-color stimulated emission depletion microscopy in living cells

Researchers are able to achieve extremely high-resolution microscopy through a process known as stimulated emission depletion (STED) microscopy. This cutting-edge imaging system has pushed the performance of microscopes significantly past the classical limit, enabling them to image features that are even smaller than the wavelength of light used to study them.

New ‘cure-all’ antiviral method discovered

In a new development that could transform how viral infections are treated, a team of researchers at MIT’s Lincoln Laboratory has designed a drug that can identify cells that have been infected by any type of virus, then kill those cells to terminate the infection.
