Fraunhofer researchers develop cell-free substrate made of advanced fibers

Regenerative medicine uses cells harvested from the patient's own body to heal damaged tissue. Fraunhofer researchers have developed a cell-free substrate containing proteins to which autologous cells bind and grow only after implantation.

New automated tool rapidly delivers large particles into mammalian cells

A new device developed by UCLA engineers and doctors eventually help scientists study the development of disease, enable them to capture improved images of the inside of cells and lead to other improvements in medical and biological research.

Study changes our understanding of how position and touch signals are combined in brain

Two types of touch information — the feel of an object and the position of an animal's limb — have long been thought to flow into the brain via different channels and be integrated in sophisticated processing regions.

Vascular mimicry can spread breast cancer to other sites

Imitation may be the sincerest form of flattery, but it can also have deadly consequences, at least when it comes to tumor cells.

Stem cell disease model reveals how tumor suppressor may drive bone cancer

Using induced pluripotent stem cells (iPSCs), a team led by Mount Sinai researchers has gained new insight into genetic changes that may turn a well known anti-cancer signaling gene into a driver of risk for bone cancers, where the survival rate has not improved in 40 years despite treatment advances.

Winners of GSA poster awards announced at 56th Annual Drosophila Research Conference

The Genetics Society of America (GSA) and the Drosophila research community are pleased to announce the winners of the GSA poster awards at the 56th Annual Drosophila Research Conference, which took place in Chicago, IL, March 4-8, 2015.

DFG selects 10 researchers to receive 2015 Heinz Maier-Leibnitz Prize

This year's recipients of the most important prize for early career researchers in Germany have been announced. The selection committee, appointed by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) and the German Federal Ministry of Education and Research (BMBF), has chosen ten researchers, five women and five men, to receive the 2015 Heinz Maier-Leibnitz Prizes.

Protein-degrading enzyme can trigger strong allergic reactions through skin

Papain is an important industrial protein-degrading enzyme that is used, for example, in the food and cosmetic industries.

Administration of selenide protects heart tissue post cardiac arrest, shows study

Damage to heart muscle from insufficient blood supply during cardiac arrest and reperfusion injury after blood flow is restored can be reduced by nearly 90 percent if selenide, a form of the essential nutrient selenium, is administered intravenously in the wake of the attack, according to a new preclinical study by researchers at Fred Hutchinson Cancer Research Center.

Researchers identify phenomenon that explains effects of oxidative stress on immune cells

You're up in the mountains, the snow is blindingly white, and the sun is blazing down from the sky: ideal skiing conditions - but any skiers carrying the herpes virus might also have to reckon with the onset of cold sores after their day out.

Scientists identify chemical compounds that block cancer-causing oncoprotein

A team of scientists at the University of Kansas has pinpointed six chemical compounds that thwart HuR, an "oncoprotein" that binds to RNA and promotes tumor growth.

New fluorescent probes detect problems related to lysosomes

Lysosomes are the garbage disposals of animal cells. As the resources are limited in cells, organic materials are broken down and recycled a lot -- and that's what lysosomes do.

Researchers use new gene editing tool to cut HIV DNA

The virus that causes AIDS is an efficient and crafty retrovirus. Once HIV inserts its DNA into the genome of its host cells, it has a long incubation period, and can remain dormant and hidden for years.

Hedione scent generates sex-specific activation patterns in brain

The question if humans can communicate via pheromones in the same way as animals is under debate. Cell physiologists at the Ruhr-Universität Bochum have demonstrated that the odorous substance Hedione activates the putative pheromone receptor VN1R1, which occurs in the human olfactory epithelium.
