A study out of Mississippi State University evaluated the impact insect pest management strategies have on the economic return of small-scale tomato production. The results of this evaluation are published in the article "Economic Effect of Insect Pest Management Strategies on Small-scale Tomato Production in Mississippi" in the open access online journal HortTechnology.
Humans began developing a complex culture as early as the Stone Age. This development was brought about by social interactions between various groups of hunters and gatherers, a UZH study has now confirmed. The researchers mapped the social networks of present-day hunter-gatherers in the Philippines and simulated the discovery of a medicinal plant product.
Ultrafast, multidimensional spectroscopy unlocks macroscopic-scale effects of quantum electronic correlations.
Researchers found that low-energy and high energy states are correlated in a layered, superconducting material LSCO (lanthanum, strontium, copper, oxygen).
Exciting the material with an ultrafast (
The strong correlation between the energy of this coherence and the optical energy of the emitted signal indicates a coherent interaction between the states at low and high energy.
It is a spectacular butterfly breed with an intriguing back story ... now scientists have revealed how male-killing bacteria are helping to create a dazzling hybrid of the African monarch.
Researchers have shed new light on the complex reproductive process which dictates that only female offspring of the Danaus chrysippus survive - all in close proximity to Kenya's capital, Nairobi.
The balance between weight gain and weight gain loss is predominantly determined by what you eat, how much you eat, and by how much exercise you get. But another important factor is often neglected... Published February 27 in the open-access journal PLOS Biology, research conducted by Kevin Kelly, Owen McGuinness, Carl Johnson and colleagues of Vanderbilt University, USA shows that it's not just how many calories you eat, but WHEN you eat them that will determine how well you burn those calories.
Like many poisonous animals, the African monarch butterfly's orange, white and black pattern warns predators that it is toxic. Warning patterns like this are usually consistent across individuals to help predators learn to avoid them. However, a recent study, published February 27 in the open-access journal PLOS Biology, shows how a population of African monarch butterflies (Danaus chrysippus) breaks this rule and has highly variable warning patterns.
New research suggests that companies looking to promote their latest environmentally friendly product should downplay its green credentials if they want consumers to buy it.
By highlighting green attributes through advertising, in some situations firms risk generating associations with weak product performance, say researchers from the University of East Anglia (UEA) and University of Leeds. This is because of the performance ability sometimes associated with green products, whereby consumers perceive them as being less effective.
Leesburg, VA, February 28, 2020--Although the imaging features of novel coronavirus disease 2019 (COVID-19) are variable and nonspecific, the findings reported thus far do show "significant overlap" with those of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), according to an ahead-of-print article in the American Journal of Roentgenology (AJR).
WHAT:
The emergence and rapid increase in cases of coronavirus disease 2019 (COVID-19), a respiratory illness caused by a novel coronavirus, pose complex challenges to the global public health, research and medical communities, write federal scientists from NIH's National Institute of Allergy and Infectious Diseases (NIAID) and from the Centers for Disease Control and Prevention (CDC). Their commentary appears in The New England Journal of Medicine.
Scientists at the University of Sussex have measured a property of the neutron - a fundamental particle in the universe - more precisely than ever before. Their research is part of an investigation into why there is matter left over in the universe, that is, why all the antimatter created in the Big Bang didn't just cancel out the matter.
Please Note: The 2020 American Physical Society (APS) March Meeting that was to be held in Denver, Colorado from March 2 through March 6 has been canceled. The decision was made late Saturday (February 29), out of an abundance of caution and based on the latest scientific data available regarding the transmission of the coronavirus disease (COVID-19). See our official release on the cancelation for more details.

A new compound has the potential to bind to DNA and activate genes, which could lead to new treatments for cancers and hereditary diseases. Zutao Yu, Ganesh Pandian Namasivayam, and Hiroshi Sugiyama of Kyoto University's Integrated Cell-Material Sciences (iCeMS) collaborated with colleagues in Japan and the USA to design and test a compound that could target specific DNA sequences and recruit gene-modifying molecules. Their findings were published in the journal ChemComm.
Biofuel is often touted as a clean fuel, but the fact that it is made using food sources is a major drawback. To address this issue, there has been continuous research on the development of second-generation biofuels using lignocellulosic biomass.
