Tiny but mighty: Microgreens could play an important role in feeding a sustainable future
Feeding 8 billion humans requires ingenuity and innovation. Zhenlei Xiao is an associate professor in residence in the UConn's College of Agriculture, Health and Natural Resources Department of Nutritional Sciences and her research focuses on tiny, nutrient-dense, and fast-growing microgreens, which could help in feeding the growing population, both on Earth and potentially in space.
Oil industry activity likely triggered large Alberta earthquake, finds study
A new study by Stanford University researchers has found that one of the most powerful earthquakes ever recorded in Alberta, Canada, was likely caused by oil and gas activity.
Women occupy few academic jobs in Ghana: Culture and society's expectations are to blame, says researcher
In many parts of the world, men dominate the higher education sector. A 2022 UNESCO report found that, globally, fewer than two out of five senior academics are women. In an earlier report it showed that less than 30% of the world's researchers are women.
An experimental method for examining ultra-light dark matter using millimeter-wave sensing
There may have been more than one way to bring the biblical Goliath down, but David chose to attack using a small stone with a slingshot.
An 'ecosystem' of tools to boost machine learning-based design of metal–organic frameworks
A team of chemists and computer scientists from the Swiss Federal Institute of Technology Lausanne, the University of California and Institut des Sciences et Ingenierie Chimiques, Ecole, have developed an ecosystem of tools to boost machine-learning-based design of metal-organic frameworks.
Scientists are using machine learning to forecast bird migration and identify birds in flight by their calls
With chatbots like ChatGPT making a splash, machine learning is playing an increasingly prominent role in our lives. For many of us, it's been a mixed bag. We rejoice when our Spotify For You playlist finds us a new jam, but groan as we scroll through a slew of targeted ads on our Instagram feeds.
Why thousands of volunteers are transcribing the notebooks of the scientist who inspired Mary Shelley's Frankenstein
Sir Humphry Davy (1778–1829) is usually remembered as the inventor of a revolutionary miner's safety lamp. But his wild popularity came as much from his influence on popular culture as it did from his contributions to chemistry and applied science.
Jackrabbits with higher variability in color genes may be better prepared for snow loss due to climate change
A team of climate scientists and biologists from Universidade do Porto, in Portugal, working with colleagues from the University of Montana and the Denver Museum of Nature & Science, both in the U.S., has found that jackrabbits living in mountainous areas, such as the Rockies, that have higher variability in color genes may be better prepared for snow loss due to climate change. In their study,...
Researchers develop an optimal silicon disulfide production technology to boost all-solid-state battery performance
A team led by Dr. Ha Yoon-Cheol, a Principal Researcher of Next Generation Battery Research Center at the Korea Electrotechnology Research Institute (KERI) and Dr. Cheol-Min Park, a Professor of School of Materials Science and Engineering at Kumoh National Institute of Technology (KIT), has developed a low-cost production technology for silicon disulfide (SiS2) for solid-state electrolytes...
African trypanosomes mapped for the first time to understand evolution and potential treatments
A parasite which has devastating impacts on agriculture and human health is the first pathogen to have its proteins located and mapped within its cells—providing clues to their function and helping to identify potential drug targets.
How afforestation by aerial sowing affects topsoil physicochemical properties in deserts
Large-scale afforestation in arid and semi-arid areas is one of the most effective approaches to combat desertification at present. Afforestation by aerial sowing is an effective measure that can promote vegetation restoration without subsequent artificial management, and can be widely employed in other ecosystems with similar vegetation degradation problems in the short term.
Scientists and maple syrup producers develop a rapid test that analyzes the quality of maple sap
Quebec is a leader in maple syrup production and its "liquid gold" is world-renowned for its quality. To maintain this high standard, the Quebec Maple Syrup Producers association has partnered with scientists at Université de Montréal to develop a portable test to predict the quality of the syrup based on the harvested sap.
How parents' smartphone use affects their kids
When it comes to raising children in the digital age, one of the worst things a parent can do is give their kid a smartphone and hope for the best. Turns out, same goes for the grownups.
Graphene grows—physicists find a way to visualize it
Graphene is one of the strongest materials. On top of that, it is exceptionally good at conducting heat and electrical currents, making it one of the most special and versatile materials we know. For all these reasons, the discovery of graphene was awarded the Nobel Prize in Physics in 2010.
New study explores the 'tsunami' in Venus's clouds
A group of scientists from the University of Seville, in collaboration with experts from the University of the Basque Country, has led the first detailed study of the evolution of the discontinuity of Venus's clouds, a gigantic atmosphere wave with the appearance of a "tsunami" that is propagated in the planet's deepest clouds and which, it is believed, may be playing a very significant role in...
Researchers find new function of oil regulator GmZF351 in soybean stress tolerance
Soybean production is very limited in China. To increase the soybean yield, there is an urgent need to develop soybean varieties that can grow and adapt to the vast areas of saline, alkaline and arid lands.
Study proves red light promotes growth of Haematococcus pluvialis
Prof. Huang Qing's group from Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS) has made progress on red-light-promoted photoautotrophic growth of Haematococcus pluvialis (H. pluvialis) and the related carbon fixation mechanism. The study was published in Aquaculture.
The science of moon hopping
The videos of the first moon landing with astronauts bouncing around the lunar surface are looking like a lot of fun—but jumping around on the moon could also be good for astronaut's muscles, bones and the cardiorespiratory system.
Researchers find 155 new massive pulsating stars or candidates
Researchers led by Dr. Shi Xiangdong and Prof. Qian Shengbang from Yunnan Observatories of the Chinese Academy of Sciences (CAS) have detected a total of 155 massive pulsating stars or candidates based on TESS, LAMOST and Gaia data.
How Muslims and Jews see each other in Western countries
Jewish-Muslim relations have been complicated for centuries, but assumptions that all Jews and Muslims are eternal enemies are proven wrong by a comprehensive survey review conducted by a researcher in Indiana University's Institute for the Study of Contemporary Antisemitism.
Carbonatitic liquid acts as medium for transferring carbon from slab to subarc mantle
Deep carbon cycling at subduction zones affects the long-term habitability of Earth's surface by regulating atmospheric CO2 concentrations. How the carbon is transferred from the slab to the subarc mantle has thus far eluded researchers.
