RAMBO speeds searches on huge DNA databases
Rice method cuts indexing times from weeks to hours, search times from hours to minutes Rice University computer scientists are sending RAMBO to rescue genomic researchers who sometimes wait days or weeks for search results from enormous DNA databases. DNA sequencing is so popular, genomic datasets are doubling in size every two years, and the tools to search the data haven't kept pace.

New Algorithm Helps Autonomous Vehicles Find Themselves, Summer or Winter
Deep learning makes visual terrain-relative navigation more practical Without GPS, autonomous systems get lost easily. Now a new algorithm developed at Caltech allows autonomous systems to recognize where they are simply by looking at the terrain around them-and for the first time, the technology works regardless of seasonal changes to that terrain.

Algorithm Uses Mass Spectrometry Data to Predict Identity of Molecules
Carnegie Mellon University New method saves time, money in developing new drugs An algorithm designed by researchers from Carnegie Mellon University's Computational Biology Department and St. Petersburg State University in Russia could help scientists identify unknown molecules. The algorithm, called MolDiscovery, uses mass spectrometry data from molecules to predict the identity of unknown substances, telling scientists early in their research whether they have stumbled on something new or merely rediscovered something already known.

UW researchers can turn a single photo into a video
UW researchers can turn a single photo into a video
Sometimes photos cannot truly capture a scene. How much more epic would that vacation photo of Niagara Falls be if the water were moving? All that's missing is the roar of the water and the feeling of the spray on your face. The team's method can animate any flowing material, including smoke and clouds.

Insulators: Safe under Maximum Load
Insulators: Safe under Maximum Load
Insulator strings connect the live conductor to overhead-line towers. Researchers at TU Graz simulated for the first time when and under what conditions different loads act on these strings. Overhead lines will thus be made even safer. Another picture for download can be found at the end of the text Though small and inconspicuous, they literally play a supporting role in the operational safety of high-voltage lines: insulator strings.

Robot chemist offers insight into the origins of life
A robotic 'evolution machine' capable of exploring the generational development of chemical mixtures over long periods of time could help cast new light on the origins of life, scientists say. A team of chemists from the University of Glasgow developed the robot, which uses a machine-learning algorithm to make decisions about which chemicals from a selection of 18 to combine in a reactor, and how to set conditions under which the reaction occurs.

Time crystals’ time is coming
Rice's Pagano part that 'pushes' exotic matter to characterize its dynamics A recently arrived Rice University professor preparing to study quantum systems assembled from the ground up with individual atoms has two significant papers on which to build his reputation. Guido Pagano , who joined Rice's Physics and Astronomy Department right before the COVID-19 pandemic, is co-author of a new paper in Science that studies the dynamics of time crystals , materials that oscillate through changes over time when "pushed" by an outside source of energy, like an external drive.

Ocean microplastics: First global view shows seasonal changes and sources
Satellites reveal fluctuation in the Great Pacific Garbage Patch and releases from the Yangtze River An estimated 8 million tons of plastic trash enters the ocean each year, and most of it is battered by sun and waves into microplastics-tiny flecks that can ride currents hundreds or thousands of miles from their point of entry The debris can harm sea life and marine ecosystems, and it's extremely difficult to track and clean up.

’PrivacyMic’: For a smart speaker that doesn’t eavesdrop
Prototype technology could enable smart home systems that don't record speech Microphones are perhaps the most common electronic sensor in the world, with an estimated 320 million listening for our commands in the world's smart speakers. The trouble is that they're capable of hearing everything else, too.

Early endeavours on the path to reliable quantum machine learning
Early endeavours on the path to reliable quantum machine learning
The future quantum computers should be capable of super-fast and reliable computation. Today, this is still a major challenge. Now, computer scientists led by ETH Zurich conduct an early exploration for reliable quantum machine learning. Anyone who collects mushrooms knows that it is better to keep the poisonous and the non-poisonous ones apart.

Machine Learning Platform That Mines Nature for New Drugs
Carnegie Mellon University Researchers from Carnegie Mellon University's Computational Biology Department in the School of Computer Science have developed a new process that could reinvigorate the search for natural product drugs to treat cancers, viral infections and other ailments. The machine learning algorithms developed by the Metabolomics and Metagenomics Lab match the signals of a microbe's metabolites with its genomic signals and identify which likely correspond to a natural product.

Ultra-high-density hard drives made with graphene store ten times more data
Ultra-high-density hard drives made with graphene store ten times more data
Graphene can be used for ultra-high density hard disk drives (HDD), with up to a tenfold jump compared to current technologies, researchers at the Cambridge Graphene Centre have shown. Considering that in 2020, around 1 billion terabytes of fresh HDD storage was produced, these results indicate a route for mass application of graphene in cutting-edge technologies Andrea Ferrari The study was carried out in collaboration with teams at the University of Exeter, India, Switzerland, Singapore, and the US.

Mass scale manipulation of Twitter Trends discovered
Mass scale manipulation of Twitter Trends discovered
New EPFL research has found that almost half of local Twitter trending topics in Turkey are fake, a scale of manipulation previously unheard of. It also proves for the first time that many trends are created solely by bots due to a vulnerability in Twitter's Trends algorithm. Social media has become ubiquitous in our modern, daily lives.

Researchers create a camera that knows exactly where it is
Researchers from the University of Bristol have demonstrated how a new special type of camera can build a pictorial map of where it has been and use this map to know where it currently is, something that will be incredibly useful in the development of smart sensors, driverless cars and robotics. Knowing where you are on a map is one of the most useful pieces of information when navigating journeys.

Supercomputer simulations unlock space weather puzzle
Scientists have long questioned why the bursts of hot gas from the Sun do not cool down as fast as expected, and now a UCL-led team of researchers have used a supercomputer to find out why. The team will now compare their simulations with 'real' data from the European Space Agency's flagship Solar Orbiter mission, with the hope that it will confirm their predictions and provide a conclusive answer.
