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.

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...

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.

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...

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.

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.

New strategy boosts acidic carbon dioxide electrolysis performance

Renewable electricity-driven carbon dioxide (CO2) electrolysis can convert CO2 into valuable fuel and chemicals. However, one of the key challenges hindering CO2 electrolysis toward practical application is the severe carbon loss under alkaline and neutral conditions, resulting in low CO2 utilization efficiency (

A new approach to optical sensing, an increasingly in-demand technology

In the past decade, optical sensing tasks have become more demanding. As a result, it has become critical to build miniaturized, inexpensive sensors that can be integrated on-chip to enable mobile applications in smart phones, autonomous vehicles, robots, and drones. Also, algorithms are playing an increasingly important role in sensing, and many recent developments have utilized machine-learning...

Astronomers discover helium-burning white dwarf

A white dwarf star can explode as a supernova when its mass exceeds the limit of about 1.4 solar masses. A team led by the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching and involving the University of Bonn has now found a binary star system in which matter flows onto the white dwarf from its companion.
