Engineers combine light and sound to see underwater
Posted by Saúl Morales Rodriguéz in categories: biological, drones, military
Stanford University engineers have developed an airborne method for imaging underwater objects by combining light and sound to break through the seemingly impassable barrier at the interface of air and water.
The researchers envision their hybrid optical-acoustic system one day being used to conduct drone-based biological marine surveys from the air, carry out large-scale aerial searches of sunken ships and planes, and map the ocean depths with a similar speed and level of detail as Earth’s landscapes. Their “Photoacoustic Airborne Sonar System” is detailed in a recent study published in the journal IEEE Access.

‘The game has changed.’ AI triumphs at solving protein structures
Posted by Derick Lee in categories: biological, biotech/medical, health, robotics/AI
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.

AI Solves 50-Year-Old Biology ‘Grand Challenge’ Decades Before Experts Predicted
Posted by Shane Hinshaw in categories: biological, robotics/AI
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.

Scientists Confirm Entirely New Species of Gelatinous Blob From The Deep, Dark Sea
Posted by Shane Hinshaw in category: biological
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.

Plant science: overlooked research area that gave birth to cell biology
Posted by Genevieve Klien in categories: biological, climatology, science, sustainability
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.

Protein storytelling through physics
Posted by Genevieve Klien in categories: biological, physics, robotics/AI
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.
