Published Assessing unintended consequences in AI-based neurosurgical training


A new study shows that human instruction is still necessary to detect and compensate for unintended, and sometimes negative, changes in neurosurgeon behavior after virtual reality AI training. This finding has implications for other fields of training.
Published Hot summer air turns into drinking water with new gel device


Researchers have focused on the moisture present in the air as a potential source of drinking water for drought-stressed populations. They reached a significant breakthrough in their efforts to create drinkable water out of thin air: a molecularly engineered hydrogel that can create clean water using just the energy from sunlight.
Published Floating sea farms: A solution to feed the world and ensure fresh water by 2050



The sun and the sea -- both abundant and free -- are being harnessed in a unique project to create vertical sea farms floating on the ocean that can produce fresh water for drinking and agriculture.
Published Fossil spines reveal deep sea's past



Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought.
Published A system to keep cloud-based gamers in sync


A new technique can synchronize media streams from different networks to multiple devices with less than 10 milliseconds of delay. The technique was demonstrated on cloud gaming, but could also be applied in AR/VR applications.
Published A lightweight wearable device helps users navigate with a tap on the wrist



Scientists have developed a fabric-based wearable device that 'taps' a user's wrist with pressurized air, silently helping them navigate to their destination. The study demonstrated that users correctly interpreted which direction the device was telling them to go an average of 87% of the time. Since the wearable embeds most of its control system within the fabric itself, using air instead of electronics, it can be built lighter and more compact than existing designs.
Published New dual-arm robot achieves bimanual tasks by learning from simulation


An innovative bimanual robot displays tactile sensitivity close to human-level dexterity using AI to inform its actions.
Published Do measurements produce the reality they show us?


The measurement values determined in sufficiently precise measurements of physical systems will vary based on the relation between the past and the future of a system determined by its interactions with the meter. This finding may explain why quantum experiments often produce paradoxical results that can contradict our common-sense idea of physical reality.
Published Scientists solve mystery of why thousands of octopus migrate to deep-sea thermal springs



Researchers used advanced technology to study a massive aggregation of deep-sea octopus gathered at thermal springs near an extinct underwater volcano off the coast of Central California. Warm water from hydrothermal springs accelerates development of octopus embryos, giving young octopus a better chance of survival. The Octopus Garden is the largest known aggregation of octopus on the planet -- the size of this nursery, and the abundance of other marine life that thrives in this rich community, highlight the need to understand and protect the hotspots of life on the deep seafloor from threats like climate change and seabed mining.
Published Barnacles may help reveal location of lost Malaysia Airlines flight MH370



Geoscientists have created a new method that can reconstruct the drift path and origin of debris from flight MH370, an aircraft that went missing over the Indian Ocean in 2014 with 239 passengers and crew.
Published Heat sensor protects the Venus flytrap from fire



The sensory hairs of the Venus flytrap contain a heat sensor that warns the plant of bush fires. It reacts to rapid temperature jumps, as researchers have discovered.
Published Clever coating turns lampshades into indoor air purifiers


Indoor air pollution may have met its match. Scientists have designed catalyst-coated lampshades that transform indoor air pollutants into harmless compounds. The lampshades work with halogen and incandescent light bulbs, and the team is extending the technology so it will also be compatible with LEDs.
Published Cleaning water with 'smart rust' and magnets


Pouring flecks of rust into water usually makes it dirtier. But researchers have developed special iron oxide nanoparticles called 'smart rust' that actually makes it cleaner. The magnetic nanoparticles attract different pollutants by changing the particles' coating and are removed from water with a magnet. Now, the team is reporting a smart rust that traps estrogen hormones, which are potentially harmful to aquatic life.
Published Transforming flies into degradable plastics



Imagine using insects as a source of chemicals to make plastics that can biodegrade later -- with the help of that very same type of bug. That concept is closer to reality than you might expect. Researchers will describe their progress to date, including the isolation and purification of the insect-derived chemicals and their conversion into their bioplastics.
Published Arrays of quantum rods could enhance TVs or virtual reality devices


Using scaffolds of folded DNA, engineers assembled arrays of quantum rods with desirable photonic properties that could enable them to be used as highly efficient micro-LEDs for televisions or virtual reality devices.
Published Tattoo technique transfers gold nanopatterns onto live cells


For now, cyborgs exist only in fiction, but the concept is becoming more plausible as science progresses. And now, researchers are reporting that they have developed a proof-of-concept technique to 'tattoo' living cells and tissues with flexible arrays of gold nanodots and nanowires. With further refinement, this method could eventually be used to integrate smart devices with living tissue for biomedical applications, such as bionics and biosensing.
Published Drops of seawater contain traces of an ancient world



New research links chemical changes in seawater to volcanic activity and changes.
Published Butterflies can remember where things are over sizeable spaces



Heliconius butterflies are capable of spatial learning, scientists have discovered. The results provide the first experimental evidence of spatial learning in any butterfly or moth species.
Published Modified virtual reality tech can measure brain activity


The research team at The University of Texas at Austin created a noninvasive electroencephalogram (EEG) sensor that they installed in a Meta VR headset that can be worn comfortably for long periods. The EEG measures the brain's electrical activity during the immersive VR interactions.
Published Energy-storing supercapacitor from cement, water, black carbon


Engineers have created a 'supercapacitor' made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.
