A new study has unlocked the potential to create new materials using nanosized ‘building blocks’, by using a laser technique to examine in rich detail the structure and internal atomic motion of a small cluster containing an acetylene molecule and a single helium atom,  C₂H₂−He complex .

The technique excited single clusters and generated rotational wavepackets, which are composed of multiple waves illustrating the individual motion of atoms. The team were able to track these wavepackets in real time up to one nanosecond over many rotations.

The European Society for Medical Oncology (ESMO) has expressed concern that the proposed EU General Data Protection Regulation could make cancer research impossible and add a significant burden to both doctors and cancer patients.

The proposed wording of the regulation stipulates 'explicit and specific patient consent', meaning that researchers would have to approach patients every single time research is planned in order to consult their data or use tissue samples stored for research purposes. 

A probiotic that prevents obesity could be on the horizon, at least if an animal model translates to humans. Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice, Vanderbilt University investigators say.

A lot would have to happen before this could move to human studies - regulatory hurdles and raising millions of dollars in venture capital, but the findings in the Journal of Clinical Investigation have the researchers excited because they suggest that it may be possible to manipulate the bacterial residents of the gut — the gut microbiota — to treat obesity and other chronic diseases.

Before the European colonial era, the people who lived on the land now called California used fire to control growth and make sure they had food, fuel, tools, and objects for ritual. 

Much artificial-intelligence research addresses the problem of making predictions based on large data sets. An obvious example is the recommendation engines at retail sites like Amazon and Netflix.

But some types of data are harder to collect than online click histories —information about geological formations thousands of feet underground, for instance. And in other applications — such as trying to predict the path of a storm — there may just not be enough time to crunch all the available data.

Researchers have detected a previously unknown interaction between microorganisms and salt. When Escherichia coli cells are introduced into a droplet of salt water and left to dry, bacteria manipulate the sodium chloride crystallisation to create biomineralogical biosaline 3D morphologically complex formations, where they hibernate.

Afterwards, by rehydrating the material, bacteria are revived. The discovery was made by chance with a home microscope but made the cover of Astrobiology because it may be a way to find signs of life on other planets.
