A new study from Lund University in Sweden shows that the presence or absence of moonlight has a considerable bearing on when migratory birds take flight in the autumn.
Together with colleagues at the Department of Biology at Lund University, Gabriel Norevik studied European nightjars (Caprimulgus europaeus) and how the lunar cycle and moonlight affects the departure time when the birds start their three-month-long migrationflight to areas south of the Sahara.
Tsukuba, Japan - A research team led by the University of Tsukuba combined observations from ancient cuneiform tablets that mention unusual red skies with radioisotope data to identify solar storms that likely occurred around 679 to 655 BCE, prior to any previously datable events. This work may help modern astronomers predict future solar flares or coronal mass ejections that can damage satellite and terrestrial electronic devices.
Metal-organic frameworks (MOFs) are formed via self-assembly of metal ions and organic linkers. Due to their superior properties, such as their large surface area, high porosity and structure tunability, MOFs have recently emerged as one type of important porous materials and have attracted intense interest in many fields, such as gas storage and separation, catalysis, and energy storage. Nevertheless, MOFs still have a few weak points, which impede the use of their full potential to a great extent.
A secret weapon used by the killer rice blast fungus to infect host plants has been discovered in new research.
Rice blast is the most serious disease of rice and is caused by the fungus Magnaporthe oryzae. Each year, blast disease claims enough rice to feed 60 million people. The fungus also causes wheat blast which recently spread from South America to Bangladesh, threatening wheat production across South Asia.
While non-active family members as major shareholders and non-family members on boards and in top management teams will push for profit and encourage growth through their entrepreneurial drive, there is less risk-taking from active family members. This is especially true when there are multiple generations of the same family involved in senior roles.
New research led by Lancaster University Management School's Centre for Family Business shows family-related considerations often trump a desire to grow and expand among firms with a greater presence of family members in management.
Native to South America, imported fire ants have now spread to parts of North America and elsewhere around the world. These invasive pests have painful stings that, in some cases, can cause serious medical problems, such as hypersensitivity reactions, infections and even kidney failure. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have identified pyridine alkaloids that, along with other venom components, could contribute to these conditions.
Government and tourism officials love to tout the economic boon that professional sports bring to their cities.
Now picture those conventional claims as a basketball floating through the air.
Between the ball and the rim is a lanky, versatile 7-foot center, portrayed here by West Virginia University economists.
"Fake news" stories targeting corporations may be obnoxious, but a new study finds that they likely pose little threat to well-established brands.
"There's been a lot of work done on how the public processes and responds to fake news on social media in the context of politics, but very little research has been done on how fake news may affect brand trust," says Yang Cheng, co-author of the new study and an assistant professor of communication at North Carolina State University. "We wanted to see what kind of impact fake news could have for companies."
KANSAS CITY, MO-Two years ago, scientists from the Stowers Institute for Medical Research reported the 3D structure of the synaptonemal complex in the fruit fly Drosophila melanogaster. This large protein complex is a critical player in the segregation of chromosomes during meiosis, a process of cell division that gives rise to reproductive cells. The synaptonemal complex functions in humans and sexually reproducing animals toward achieving normal, healthy pregnancies.
URBANA, Ill. - Many low-income countries have turned to mass food fortification programs to address nutrient deficiencies in their populations. But many of these programs lack the resources needed to determine if the appropriate amount of nutrients is consistently present in those food products.
A team of University of Illinois researchers has developed an affordable, reliable paper-based sensor that works with a cellphone app - also developed at U of I - to detect levels of iron in fortified food products.
Today's commercial aircraft are typically manufactured in sections, often in different locations -- wings at one factory, fuselage sections at another, tail components somewhere else -- and then flown to a central plant in huge cargo planes for final assembly.
But what if the final assembly was the only assembly, with the whole plane built out of a large array of tiny identical pieces, all put together by an army of tiny robots?
WASHINGTON -- Although LEDs are increasingly used in low-energy lighting and displays, consumers sometimes find their light harsh or unpleasant. Findings from a new study point to the need to take age-related perception differences into account when designing white LED lighting that is more pleasing to the eye.
New Rochelle, NY, October 16, 2019--Researchers have demonstrated a close positive association between daily stress, depression symptoms, and Facebook Addiction Disorder (FAD). High daily stress can lead individuals to turn to Facebook use as a coping strategy, with depression symptoms serving as a moderator of this association, according to a study published in Cyberpsychology, Behavior, and Social Networking, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
Despite humanity's best efforts to eradicate malaria, the disease struck more than 200 million people in 2017, according to the World Health Organization. Worse yet, the parasite that causes malaria is developing resistance to many antimalarial drugs, including the mainstay, chloroquine. Researchers are actively searching for new treatments, and now, a group reporting in ACS Omega have found that aҫaí berry extracts can reduce parasites in the blood and prolong the survival of infected mice.
