Artificial intelligence has become the Swiss Army knife of the business world, a universal tool for increasing sales, optimizing efficiency, and interacting with customers. But new research explores another purpose for AI in business: to contribute to the social good. It can do so by helping businesses better serve vulnerable consumers: anyone in the marketplace who experiences limited access to and control of resources.

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant move towards the ultimate goal of reaching the quantum ground state of sound in wave-guides. Unwanted noise generated by the acoustic waves at room temperature can be eliminated. This experimental approach both provides a deeper understanding of the transition from classical to quantum phenomena of sound and is relevant to quantum communication systems and future quantum technologies.

Electrical deep brain stimulation (DBS) is a well-established method for treating disordered movement in Parkinson's disease. However, implanting electrodes in a person's brain is an invasive and imprecise way to stimulate nerve cells. Researchers report a new application for the technique, called magnetogenetics, that uses very small magnets to wirelessly trigger specific, gene-edited nerve cells in the brain. The treatment effectively relieved motor symptoms in mice without damaging surrounding brain tissue.

Researchers have designed a self-powering, battery-free, energy-harvesting sensor. Using the framework they developed, they produced a temperature sensor that can harvest and store the energy from the magnetic field that exists in the open air around a wire.

A global team of biologists has compiled nearly two decades of field data -- representing the study of more than 3,400 Darwin's finches in the Galapagos Islands -- to identify the relationship between beak traits and the longevity of individual finches from four different species.

Researchers have developed a light-based means of printing nano-sized metal structures that is 480 times faster and 35 times cheaper than the current conventional method. It is a scalable solution that could transform a scientific field long reliant on technologies that are prohibitively expensive and slow. Their method is called superluminescent light projection (SLP).

Viral respiratory infections are a significant public health concern. A study used longitudinal cohort data to create an interactive, publicly-available website, The Virome of Manhattan Project: Virome Data Explorer to visualize cohort characteristics, infection events, and illness severity factors.

The study reveals dramatic regional kelp canopy changes along the California coast over a 100-year period. During this time there was a significant increase in kelp forest canopy along the central coast, the only region of California where southern sea otters survived after being hunted nearly to extinction for their fur in the 1800s. Contrastingly, kelp canopy decreased in northern and southern regions. At the century scale, the species' favorable impact on kelp forests along the central coast nearly compensated for the kelp losses along both northern and southern California resulting in only a slight overall decline statewide during this period.

Across 21 licensed premises in England, removing the largest individual serving size of wine from the menu reduced the volume of wine sold, according to a new study.

An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.

Temperature, day length and humidity have been found to be linked to the increased spread of a diarrheal illness a new study reveals. The findings could help predict further outbreaks of the illness, potentially leading to better preparedness within health services.

A new way to recover significantly more circulating tumor DNA in a blood sample could improve the sensitivity of liquid biopsies used to detect, monitor, and guide treatment of tumors.

Tuberculosis, caused by the bacterium Mycobacterium tuberculosis (Mtb) kills upwards of 1.6 million people a year, making it one of the leading causes of death by an infectious agent worldwide -- and that number is only growing larger. How, exactly, Mtb evades the immune system isn't yet known, but a collaborative team of researchers recently discovered something surprising: prior exposure to a genus of bacteria called Mycobacterium seems to remodel the first-line defenders in the body's immune system.

A new paper describes a significant leap forward in assembling polyhedral nanoparticles. The researchers introduce and demonstrate the power of a novel synthetic strategy that expands possibilities in metamaterial design. These are the unusual materials that underpin 'invisibility cloaks' and ultrahigh-speed optical computing systems.

A new study suggests the moments that follow a distressing episode are more memorable than the moments leading up to it. The results add to our understanding of how trauma impacts memory and may improve how we evaluate eyewitness testimonies, treat PTSD, and combat memory decline in brain disorders like Alzheimer's disease.

A team of physicians, neuroscientists and engineers demonstrated two new strategies that use deep brain stimulation to improve the symptoms of Parkinson's disease. By simultaneously targeting two key brain structures and using a novel self-adjusting device, the team showed that they can efficiently target and improve disruptive symptoms caused by the movement disorder.

The collaboration between scientists, farmers and managers is crucial to improve the protection of the little bustard, an endangered steppe-land bird in Spain due to human activity. The reduction of natural habitats, the increase in irrigation and the urbanization of the land have led to having less surface areas that guarantee the survival of this vulnerable species.

A new study shows that the physics principle of 'nucleation' can perform complex calculations that rival a simple neural network. The work may suggest avenues for new ways to think about computation using the principles of physics.

Two insect-like robots, a mini-bug and a water strider may be the smallest, lightest and fastest fully functional micro-robots ever known to be created. Such miniature robots could someday be used for work in areas such as artificial pollination, search and rescue, environmental monitoring, micro-fabrication or robotic-assisted surgery. Reporting on their work in the proceedings of the IEEE Robotics and Automation Society's International Conference on Intelligent Robots and Systems, the mini-bug weighs in at eight milligrams while the water strider weighs 55 milligrams. Both can move at about six millimeters a second.

Protecting the world ocean against accelerating damage from human activities could be cheaper and take up less space than previously thought, new research has found.
