Gene chips, or microarrays, have proven to be immensely important in measuring the activity of thousands of genes at once in such cells as cancer cells or immune cells. The use of these chips has given scientists snapshots of gene activity that lead to better understanding of the genetic machinery of the cells. This understanding has led to new ways to kill cancers or to manipulate the immune system, for example.
Gene chips consist of vast arrays of thousands of specific genetic segments spotted onto tiny chips. When gene extracts of cells are applied to the chips, labeled with fluorescent indicators, genes from the cell extracts attach to their complementary counterparts on the chips. Measurements of the fluorescence of each spot give scientists an indication of the activity of particular genes.
As vital as they are to studies of individual types of cells, gene chips have proven to be less useful in efforts to understand the genetic signatures of specific brain cells, because a myriad of subtly different subtypes of brain cells are intertwined in brain tissue.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
