Artificial intelligence (AI) has solved one of biology’s grand challenges: predicting how proteins curl up from a linear chain of amino acids into 3D shapes that allow them to carry out life’s tasks. Today, leading structural biologists and organizers of a biennial protein-folding competition announced the achievement by researchers at DeepMind, a U.K.-based AI company. They say the DeepMind method will have far-reaching effects, among them dramatically speeding the creation of new medications.

A long-standing and incredibly complex scientific problem concerning the structure and behaviour of proteins has been effectively solved by a new artificial intelligence (AI) system, scientists report.

DeepMind, the UK-based AI company, has wowed us for years with its parade of ever-advancing neural networks that continually trounce humans at complex games such as chess and Go.

Protein folding, one of the biggest mysteries in biology, has been solved by artificial intelligence company DeepMind.

For the first time, scientists with the National Oceanic and Atmospheric Administration (NOAA) have formally identified a new species of undersea creature based solely on high-definition video footage captured at the bottom of the ocean.

And what an undersea creature it is. Meet Duobrachium sparksae – a strange, gelatinous species of ctenophore, encountered by the remotely operated vehicle (ROV) Deep Discoverer during a dive off the coast of Puerto Rico.

Synthetic biology tools used to engineer T cells that work like living computers and recognize antigen combinations in solid tumors.

Plant scientists have revolutionised science and innovation. Research around the cell or cell biology was born out of plant science.

Researching plants is vital for our food security, maintaining our ecosystems and in our fight against climate change. Plant science is equally important to generate new knowledge that breaks disciplinary barriers to revolutionise several fields of research and innovation. But despite its valuable contribution, scientists and prospective young scientists often overlook plant science. It’s because of this low recognition, plant science doesn’t get the same prestige as other disciplines. This is detrimental to the future of plant science as bright young students continue to choose a career away from plant science. I never considered studying plants myself — it was entirely accidental that I studied plant science.

In other words, scientists and prize committees question the influence of basic plant science across different disciplines.

Computational molecular physics (CMP) aims to leverage the laws of physics to understand not just static structures but also the motions and actions of biomolecules. Applying CMP to proteins has required either simplifying the physical models or running simulations that are shorter than the time scale of the biological activity. Brini et al. reviewed advances that are moving CMP to time scales that match biological events such as protein folding, ligand unbinding, and some conformational changes. They also highlight the role of blind competitions in driving the field forward. New methods such as deep learning approaches are likely to make CMP an increasingly powerful tool in describing proteins in action.

### BACKGROUND

Circa 2014

Forget blue whales and giant redwood trees. The biggest living organism is over 2 miles across, and you’ll hardly ever see it.

Subramanian Sundaram, a biological engineer affiliated with both Boston University and Harvard has been looking into the current state of robot hands and proposed ideas regarding where new research might be heading. He has published a Perspective piece in the journal Science outlining the current state of robotic hand engineering.

By almost any measure, robot hand design has evolved into sophisticated territory—robot hands can not only pick things up and let them go, they can sometimes “feel” things and respond in human-like ways—and in many cases, do it with extreme dexterity. Unfortunately, despite substantial inroads to giving robot hands human-like abilities, they still fall far short. Sundaram notes that one area where they need major improvement is in sensing things the way humans do, namely: feeling pressure, temperature and that hard-to-classify sense, pleasure. You cannot tickle a robot hand, for example, and expect a human-like response. Sundaram explains in great detail what is known about the human hand and how it processes sensations, and suggests that robot analogs might possible. He notes that not everything about a robot hand needs to be done in the same way as the human hand.
