Algorithm that performs as accurately as dermatologists
A study has now been presented that boosts the evidence for using AI solutions in skin cancer diagnostics. With an algorithm they devised themselves, scientists show the capacity of technology to perform at the same level as dermatologists in assessi.....»»
TikTok algorithm makes room for personal choice; age restrictions; less depressing content
The TikTok algorithm has been at once the key to the success of the video streaming app, and the biggest criticism leveled against it. But it is now offering users the ability to filter out topics you don’t want to see. The company is also introdu.....»»
Researchers develop algorithm to divvy up tasks for human-robot teams
Researchers have developed an algorithmic planner that helps delegate tasks to humans and robots. The planner, 'Act, Delegate or Learn' (ADL), considers a list of tasks and decides how best to assign them. The researchers asked three questions: When.....»»
Great air quality for the Great Lakes
Air quality planning agencies in the U.S. Great Lakes region now include high-resolution NASA satellite data and near real-time Earth observations in their ozone pollution assessments. Creating models that accurately predict the complex lake and land.....»»
Soft but tough: Biohybrid material performs like cartilage
Producing biomaterials that match the performance of cartilage and tendons has been an elusive goal for scientists, but a new material created at Cornell demonstrates a promising new approach to mimicking natural tissue......»»
How the Large Hadron Collider Will Hunt for Dark Matter
It's the world's largest particle accelerator — and after a three-year pause for upgrades, CERN's Large Hadron Collider now detects more data, runs at higher speeds, and performs at its highest energy level ever — a whopping 13.6 trillion.....»»
Dark matter: Our review suggests it"s time to ditch it in favor of a new theory of gravity
We can model the motions of planets in the Solar System quite accurately using Newton's laws of physics. But in the early 1970s, scientists noticed that this didn't work for disk galaxies—stars at their outer edges, far from the gravitational force.....»»
Machine learning begins to understand human gut
The communities formed by human gut microbes can now be predicted more accurately with a new computer model developed in a collaboration between biologists and engineers, led by the University of Michigan and the University of Wisconsin......»»
Novel catalyst radically enhances rate of conversion of carbon dioxide into solar fuels
Carbon dioxide or CO2 can potentially be used as a feedstock to be converted into carbon-neutral "solar fuels" that store energy from the sun. But for them to be competitive with fossil fuels, the chemical reaction that performs this conversion needs.....»»
Crossing fire threshold can quickly turn blazes dangerous
Global climate change has already exacerbated the risk of fire and is likely to fuel even more change as accelerating feedback loops create disastrous consequences for both biodiversity and human populations. Yet accurately predicting the risks and i.....»»
Ocean Oil Slick Map Reveals Enough Greasy Patches to Cover France--Twice
An algorithm-aided analysis of satellite images reveals the size, distribution and sources of oil slicks at sea -- Read more on ScientificAmerican.com.....»»
Algorithm finds that thousands of artificial levees are missing from US database
Over the past 300 years, humans have dramatically altered rivers through mining, draining, dredging, levee construction, and other activities. Artificial levees, for instance, provide a barrier between rivers and their floodplains to prevent flooding.....»»
Chemists create a sensor that accurately detects the saliva pH of humans
Chemists at the Ural Federal University have created a sensor for determining the pH of human saliva. This is a fluorophore with strong and stable emission, which picks up the smallest fluctuations in the pH in biological fluids. The analysis is perf.....»»
Quantum electrodynamics tested 100 times more accurately than ever
Using a newly developed technique, scientists at the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg have measured the very small difference in the magnetic properties of two isotopes of highly charged neon in an ion trap with previousl.....»»
Quantum computer succeeds where a classical algorithm fails
Quantum computers coupled with traditional machine learning show clear benefits. Enlarge / Google's Sycamore processor. (credit: Google) People have performed many mathematical proofs to show that a quantum computer will vastl.....»»
Studying grassland from space
Extensively used grassland is host to a high degree of biodiversity, and performs an important climate protection function as a carbon sink and also serves for fodder and food production. However, these ecosystem services are jeopardized if productiv.....»»
Unfreezing waters in ligand binding sites to aid in drug discovery
Cryogenic (frozen) protein structures are central to understanding function and developing drugs. Scientists at St. Jude Children's Research Hospital have created an algorithm to reveal when freezing the proteins may create "artifacts,"—errors that.....»»
Algorithm simulates the intergalactic medium of the universe
The Instituto de Astrofísica de Canarias (IAC) led the development of a new numerical procedure to reproduce the intergalactic medium obtained from a cosmological simulation of 100,000 hours of computation using big data and machine learning techniq.....»»
Samsung hit with lawsuit over battery prediction algorithm
It appears that a Dutch company isn’t too happy with the algorithm that Samsung uses to predict battery life in its Android smartphones, leading to them filing a lawsuit against the company. The post Samsung hit with lawsuit over battery prediction.....»»
Study suggests sectarian identity in Middle East tied to domestic matters, not a larger, transnational religious split
As the old adage has it, all politics is local. That might seem a quaint idea in an age of social media and global connectivity. And yet, as a study co-led by an MIT political scientist finds, it may describe Middle East politics more accurately than.....»»
Scientists use AI to update data vegetation maps for improved wildfire forecasts
A new technique developed by the National Center for Atmospheric Research (NCAR) uses artificial intelligence to efficiently update the vegetation maps that are relied on by wildfire computer models to accurately predict fire behavior and spread......»»
