Global study shows a third more insects come out after dark
2024-04-27 17:50
A groundbreaking study, led by Dr. Mark Wong of The University of Western Australia, has provided the first global picture of insect activity patterns across the fundamental day–night cycle.
Cicada-palooza! Billions of bugs to blanket America
2024-04-27 15:24
They're loud. They're sexually aroused. And for one special, cacophonous month up to a trillion of them will engulf suburbs and woodlands across America.
Getting dynamic information from static snapshots
2024-04-27 15:14
Imagine predicting the exact finishing order of the Kentucky Derby from a still photograph taken 10 seconds into the race.
Ancient Maya blessed their ballcourts: Researchers find evidence of ceremonial offerings in Mexico
2024-04-27 15:13
For sports fans, places like Fenway Park, Wembley Stadium or Wimbledon's Centre Court are practically hallowed ground.
Optical barcodes expand range of high-resolution sensor
2024-04-26 21:27
The same geometric quirk that lets visitors murmur messages around the circular dome of the whispering gallery at St. Paul's Cathedral in London or across St. Louis Union Station's whispering arch also enables the construction of high-resolution optical sensors. Whispering-gallery-mode (WGM) resonators have been used for decades to detect chemical signatures, DNA strands and even single molecules.
Ridesourcing platforms thrive on socio-economic inequality, say researchers
2024-04-26 20:54
Platforms that offer rides to passengers, such as Uber and DiDi, thrive on socio-economic inequality. By modeling the behavior of passengers and self-employed drivers, researchers of TU Delft simulated the market for ridesourcing platforms, evaluating a broad spectrum of (in)equality levels in societies.
Did Vesuvius bury the home of the first Roman emperor?
2024-04-26 20:46
A group of archaeologists, led by researchers from the University of Tokyo, announce the discovery of a part of a Roman villa built before the middle of the first century. This villa, near the town of Nola in southwestern Italy's Campania region, was found beneath a more recent, but still ancient building from the 2nd century.
Florida dolphin found with highly pathogenic avian flu: Report
2024-04-26 20:32
The case of a Florida bottlenose dolphin found with highly pathogenic avian influenza virus, or HPAIV—a discovery made by University of Florida researchers in collaboration with multiple other agencies and one of the first reports of a constantly growing list of mammals affected by this virus—has been published in Communications Biology.
A new way to study and help prevent landslides
2024-04-26 20:30
Landslides are one of the most destructive natural disasters on the planet, causing billions of dollars of damage and devastating loss of life every year. By introducing a new paradigm for studying landslide shapes and failure types, a global team of researchers has provided help for those who work to predict landslides and risk evaluations.
New algorithm cuts through 'noisy' data to better predict tipping points
2024-04-26 20:13
Whether you're trying to predict a climate catastrophe or mental health crisis, mathematics tells us to look for fluctuations.
Researchers reconstruct landscapes that greeted the first humans in Australia around 65,000 years ago
2024-04-26 20:00
Seventy thousand years ago, the sea level was much lower than today. Australia, along with New Guinea and Tasmania, formed a connected landmass known as Sahul. Around this time—approximately 65,000 years ago—the first humans arrived in Sahul, a place previously devoid of any hominin species.
High-precision blood glucose level prediction achieved by few-molecule reservoir computing
2024-04-26 19:24
A collaborative research team from NIMS and Tokyo University of Science has successfully developed an artificial intelligence (AI) device that executes brain-like information processing through few-molecule reservoir computing. This innovation utilizes the molecular vibrations of a select number of organic molecules.
Enhancing memory technology: Multiferroic nanodots for low-power magnetic storage
2024-04-26 19:10
Traditional memory devices are volatile and the current non-volatile ones rely on either ferromagnetic or ferroelectric materials for data storage. In ferromagnetic devices, data is written or stored by aligning magnetic moments, while in ferroelectric devices, data storage relies on the alignment of electric dipoles.
Researchers advance detection of gravitational waves to study collisions of neutron stars and black holes
2024-04-26 19:10
Researchers at the University of Minnesota Twin Cities College of Science and Engineering co-led a new study by an international team that will improve the detection of gravitational waves—ripples in space and time.
Automated machine learning robot unlocks new potential for genetics research
2024-04-26 19:10
University of Minnesota Twin Cities researchers have constructed a robot that uses machine learning to fully automate a complicated microinjection process used in genetic research.
New structures offer insight into how a bacterial motor powers bacterial chemotaxis, a key infectious process
2024-04-26 17:04
Bacteria existed for millennia before humans and have been infecting us from the beginning. Although we can treat infections through pharmaceuticals, bacteria continue to become resistant to treatment thanks to their rapid evolution. Bacterial infections remain a leading cause of morbidity and mortality in 2024, resulting in nearly eight million annual deaths globally.
Genomic analysis of a species of zooplankton questions assumptions about speciation and gene regulation
2024-04-26 16:40
When two animals look the same, eat the same, behave the same way, and live in similar environments, one might expect that they belong to the same species.
Genetic hope in fight against devastating wheat disease
2024-04-26 16:37
Fungal disease Fusarium head blight (FHB) is on the rise due to increasingly humid conditions induced by climate change during the wheat growing season, but a fundamental discovery by University of Adelaide researchers could help reduce its economic harm.
Thiol-ene click reaction offers a novel approach to fabricate elastic ferroelectrics
2024-04-26 16:23
A research group led by Prof. Li Runwei and Hu Benlin at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences has developed a facile and efficient approach to fabricate elastic relaxor ferroelectrics via thiol-ene click reaction.
Research investigates radio emission of the rotating radio transient RRAT J1854+0306
2024-04-26 15:40
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have investigated radio emission from a rotating radio transient known as RRAT J1854+0306. Results of the study, published April 15 on the preprint server arXiv, shed more light on the properties of this transient.
