The strange dance of ion and atom

A cold, strange and short molecule created in an experiment at the Weizmann Institute of Science following a collision between particles may shed light on chemical reactions at extremely low temperatures
The institute's scientists were looking for how to establish an efficient method for processing information in quantum computers - and unexpectedly discovered a new type of vortices that are created when two photons collide

When a particle of light sees the light

The experimental setup: microfluidic channels with a diameter of 1 micron in which E. coli bacteria were grown for several generations using a variety of fluorescent markers. These markers make it possible to follow important events in the bacterium's life cycle at the single cell level

How does a bacterium know it's time?

Dr. Oren Raz came up with an idea for a new way to circumvent the phase reconstruction problem: to combine two ultra-fast laser flashes and measure them together, so that the combination between the two would act as a hologram

The shape of the flash - how to measure a very fast phenomenon using a much slower detector

The table gathers the "disruption scores" of hundreds of patients with a brain tumor: each row refers to a pathway or biochemical process, and each column - to a sample from a specific patient. Each color symbolizes a number - the value of the "disruption score" of the biochemical pathway, as calculated for the patient. Dark blue indicates normal activity of the biochemical pathway in healthy brain tissue, while dark red indicates a strong deviation from normal behavior. The group of samples of brain cells from healthy people appears as a dark blue vertical bar, labeled TgS7, which appears in the middle of the table. The bar marked TgS15 describes the subgroup of patients with a longer survival prognosis
