Researchers have been using passive acoustic recordings of whale calls to track their movements. They have found that four of the six baleen whale species found in the western North Atlantic Ocean -- humpback, sei, fin and blue whales -- have changed their distribution patterns in the past decade. The recordings were made over 10 years by devices moored to the seafloor at nearly 300 locations from the Caribbean Sea to western Greenland.
Lithium-ion batteries are recognized for their high energy density in everything from mobile phones to laptop computers and electric vehicles, but as the need for grid-scale energy storage and other applications becomes more pressing, researchers have sought less expensive and more readily available alternatives to lithium.
Berkeley -- Widespread use of pesticides and other agrochemicals can speed the transmission of the debilitating disease schistosomiasis, while also upsetting the ecological balances in aquatic environments that prevent infections, finds a new study led by researchers at the University of California, Berkeley.
LOS ALAMOS, N.M., July 16, 2020--A new device that relies on flowing clouds of ultracold atoms promises potential tests of the intersection between the weirdness of the quantum world and the familiarity of the macroscopic world we experience every day. The atomtronic Superconducting QUantum Interference Device (SQUID) is also potentially useful for ultrasensitive rotation measurements and as a component in quantum computers.
Forms of dementia, including Alzheimer's disease, gradually affect your cognitive function by harming your memory and your ability to think and make decisions. By 2050, experts project that 13.8 million older adults in the United States will develop Alzheimer's disease and related Dementias (ADRD).
COLUMBIA, Mo. - Osteosarcoma, a common bone cancer in dogs, affects more than 10,000 dogs in the U.S. each year. While chemotherapy is generally effective at killing some of the cancer cells, the numerous side effects can be painful and often a subset of cancer cells exist that are resistant to chemotherapy.
URBANA, Ill. - Pigs that eat soybean as a regular part of their diet may be better protected against viral pathogens, a new study from University of Illinois shows. The researchers attribute the effect to isoflavones, a natural compound in soybeans.
The miniaturisation of electronic components coupled with their increasing integration density has considerably expanded heat flows, which can lead to overheating. But how to measure these nanometric events when conventional solutions such as infrared thermography cannot go below a micrometre (1,000 times bigger than a nanometre)?
In a paper published in NANO, a group of researchers from Jiangsu University of Technology, China have developed novel Cu2O-Mn3O4-NiO ternary nanocomposites by electrostatic spinning technology, which improved the performance of supercapacitors electrode materials.
WASHINGTON--Weather forecasts have become less accurate during the COVID-19 pandemic due to the reduction in commercial flights, according to new research.
A new study in AGU's journal Geophysical Research Letters finds the world lost 50-75% of its aircraft weather observations between March and May of this year, when many flights were grounded due to the pandemic.
Scientists have found the interstellar organic matter could produce an abundant supply of water by heating, suggesting that organic matter could be the source of terrestrial water.
A team led by Prof. DU Jiangfeng, Prof. SHI Fazhan and Prof. WANG Ya from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) proposed a robust electrometric method utilizing continuous dynamic decoupling (CDD) technique, where the continuous driving fields provide a magnetic-field-resistant dressed frame. The study was published in Physical Review Letters on June 19.
Honeybee colonies are bioindicators of environmental contamination in the area, since they get coated in everything that there is in the environment, including pollutants, and they end up taking it all back to their bee hives.
Diffraction is a classic optical phenomenon accounting for the light propagation. The efficient calculation of diffraction is of significant value towards the real-time prediction of light fields. The diffraction of electromagnetic (EM) waves can be catalogued into scalar diffraction and vector diffraction according to the validation of different approximation conditions. Although mathematical expressions for both optical diffraction have been presented authoritatively for ages, fundamental breakthroughs have rarely been achieved in computation algorithms.
Researches are pushing the boundaries of data speed with a brand new type of organic LEDs.
An international research team, involving Newcastle University experts, developed visible light communication (VLC) setup capable of a data rate of 2.2?Mb/s by employing a new type of organic light-emitting diodes (OLEDs).
To reach this speed, the scientists created new far-red/near-infrared, solution-processed OLEDs. And by extending the spectral range to 700-1000?nm, they successfully expanded the bandwidth and achieved the fastest-ever data speed for solution-based OLEDs.
