The 'net' is closing in on more viable biological control agents to fight the scourge of the fall armyworm (FAW) pest which is already wreaking havoc in most African countries as well as more than a dozen Asian countries including China and India.
CABI scientists teamed up with colleagues from the International Institute of Tropical Agriculture (IITA) and the Plant Protection and Regulatory Services Directorate (PPRSD) in Ghana to conduct new research which is another step closer to finding more biological control options to fight the FAW menace.
The international collaborative team of Tokyo University of Agriculture and Technology (TUAT) (Japan), IIT Ropar (India), Osaka Univ. (Japan) has discovered for the first time in the scientific development that "partially miscibility", in which the two liquids do not mix completely with finite solubility, is capable of deforming the liquid-liquid interface.
Australians are increasingly being diagnosed with cancers that will do them no harm if left undetected or untreated, exposing them to unnecessary surgeries and chemotherapy, says a new study published online today in the Medical Journal of Australia.
The research, led by Professor Paul Glasziou, the Director of the Institute for Evidence-Based Healthcare at Bond University, drew on data from the Australian Institute of Health and Welfare to compare how the lifetime risk of five cancers had changed between 1982 and 2012.
Water issuing from an ordinary faucet tells a complex tale of its journey through a pipe. At high velocities, the faucet's gushing stream is turbulent: chaotic, disorderly -- like the crash of ocean waves.
Compared to orderly laminar flows, like the faucet's steady stream at low velocities, scientists know little about turbulence. Even less is known about how laminar flows become turbulent. A mix of orderly and disorderly flows, transitional flows occur when fluids move at intermediate velocities.
Computer modelling and long-term ecological monitoring will be essential to assess the environmental risks of the rapidly growing number of chemicals across the world, according to a new review paper in the journal Science.
January 24, 2020 - As we enter a new year and a new decade, many states have enacted legislation affecting the roles of advanced practice registered nurses (APRNs) in terms of practice authority, reimbursement, and prescriptive authority, according to the 32nd Annual Legislative Update in the January issue of The Nurse Practitioner, published by
Approximately one-quarter of patients who are prescribed opioids for chronic pain misuse them, with five to 10 percent developing an opioid use disorder or addiction. In a new study, published Jan. 14, 2020 in PNAS, researchers at University of California San Diego School of Medicine found that opioid dependence produced permanent changes in the brains of rats.
Irvine, CA - January 24, 2020 - Individuals with a history of early life adversity (ELA) are disproportionately prone to opioid addiction. A new UCI-led study reveals why.
Published in Molecular Psychiatry, the study titled, "On the early life origins of vulnerability to opioid addiction," examines how early adversities interact with factors such as increased access to opioids to directly influence brain development and function, causing a higher potential for opioid addiction.
Yard signs for a local politician captured the curiosity of Katherine Haenschen.
"I was driving through the region and noticed the same campaign was using a different font on signs in rural areas than on the signs in town," said Haenschen, an assistant professor in the Department of Communication. "I thought, why would this candidate be using multiple fonts?"
An expert in political messaging, Haenschen and Daniel Tamul, also an assistant professor in the Department of Communication, transformed the question into a captivating research project.
In 2011, China's Supreme Court dealt a blow to the property rights of women by ruling that family homes purchased before marriage automatically belong to the registered buyer upon divorce, historically the husband.
To mitigate climate change and safeguard ecosystems, we need to make drastic changes in our consumption and transport behaviors. A new IIASA study shows how even minor changes to available infrastructure can trigger tipping points in the collective adoption of sustainable behaviors.
Stanford scientists have completed the first global census of diverse proteins sprouting tree-like from the outer membrane of a cell. These cell surface proteins govern how cells interact with one another and how they assemble into tissues and organs such as hearts and brains.
"Cell architecture is determined by cell-cell interactions, and these interactions are mediated by molecules on the cell surface. They're the business end of things," said Jiefu Li, a graduate student in the biology department at Stanford University.
Rich countries vary a lot when it comes to health and social problems. A comparison of social ills ranging from intentional homicides to obesity rates in 40 rich societies shows that Asian and European countries fare much better than Anglophone and Latin American countries. The most problem-ridden countries are Trinidad and Tobago, Uruguay and the United States. The positive end of the list is headed by Japan, South Korea and Singapore, followed by Iceland, Norway and Switzerland. Germany ranks 15th just behind Austria.
Human pressure on the world's ocean accelerated sharply at the start of the 21st century and shows no sign of slowing, according to a comprehensive new analysis on the state of the ocean.
Scientists have dubbed the dramatic rise the "Blue Acceleration". The researchers from the Stockholm Resilience Centre, Stockholm University, synthesized 50-years of data from shipping, drilling, deep-sea mining, aquaculture, bioprospecting and much more. The results are published in the journal One Earth, 24 January.
