Human exposure to unnecessary and potentially harmful chemicals could be greatly reduced if manufacturers add chemicals only when they are truly essential in terms of health, safety and functioning of society. That's the conclusion of a study published today in Environmental Science: Processes & Impacts, a peer-reviewed journal published by the Royal Society of Chemistry.

It's a feat three decades in the making: Harvard University chemists have achieved what a new paper calls a "landmark in drug discovery" with the total synthesis of halichondrin. Known to be a potent anti-cancer agent in mouse studies, and found naturally in sea sponges -- though only ever in minuscule quantities -- the halichondrin class of molecule is so fiendishly complex that it had never been synthesized on a meaningful scale in the lab.

LEXINGTON, Ky. (June 17, 2019) - Discipline and how it is administered in schools across the U.S. continues to be a hotly debated topic. Now a University of Kentucky doctoral graduate's expansive research on the subject has been published in the Journal of School Psychology and is gaining widespread attention from teachers, administrators, and researchers.

Developmental disorders are neurologically-based conditions that affect the acquisition of specific skills such as attention, memory, language and social interaction. Although they have a genetic cause, this is often difficult to detect through standard genetic analysis of the parents. The mutation found in the affected child is therefore termed a 'de novo' mutation (DNM).

A study out of Clemson University has demonstrated that inexpensive, easy-to-use temperature controllers are able to provide reliable set temperatures for the detailed observation of developmental rates in response to different temperature treatments.

Researchers Douglas Bielenberg and Ksenija Gasic engaged a methodical examination of the practical applications of these temperature control devises on cut stems, buds, and seeds.

A study out of Indiana and Purdue Universities sought to gain a better understanding, from the perspective of farmers, of the challenges and advantageous opportunities associated with using high tunnels for specialty crops in Indiana.

Across the United States and Canada, demand for local specialty cut flowers is increasing, and production has correspondingly jumped. To accurately assess the needs of the industry, John Dole, Cristian Loyola, and Rebecca Dunning electronically surveyed 1098 cut flower producers and handlers regarding their current cut flower production and postharvest problems and customer issues.

The green industry in the United States is comprised of production and wholesale nurseries and wholesale/retail distribution centers, as well as related marketing interests. While the green industry traditionally has been among the fastest growing business sectors in the U.S. national economy, recently some of its segments have become stagnant or have declined in economic health.

DURHAM, N.C. -- Researchers at Duke University have isolated a cluster of neurons in a mouse's brain that are crucial to making the squeaky, ultrasonic 'songs' a male mouse produces when courting a potential mate.

In fact, they now understand these neurons well enough to be able to make a mouse sing on command or to silence it so that it can't sing, even when it wants to impress a mate.

John Stommel of the Agricultural Research Service of the US Department of Agriculture (USDA-ARS) has investigated the desirability for, and practicality of, producing snack peppers, both sweet and hot, with low seed count.

His findings are in the article, "Reduced Seed Count Improves Versatility and Propagation of Small-fruited Peppers (Capsicum annuum L.) for Specialty Markets," published in HortScience.

"Epidemiological and clinical research and public policy in Europe are generally considered to be comprehensive and successful, but there is potential for improvement and scope for new opportunities", explains Professor Ziad A. Massy, Paris/France, Chair of the Nephrology and Public Policy Committee. "Especially in nephrology we have to further intensify our research activities. With 850 million people suffering from kidney diseases of any kind worldwide, nephrology has to be one of the main areas of medical research."

Like the infamous "Joe Camel" advertisements for cigarettes in the 1980s and 90s, the use of cartoon characters in ads for e-cigarettes and e-liquids may be attracting young people to the nicotine-delivery products, according to a new USC study.

Researchers from Dartmouth College, New Hampshire have found evidence that players born in the first quarter of the year are more likely to play in the National Football League.

Studies show children born earlier in the year may develop more quickly than their younger peers with higher participation in, for example, sports, than those born towards the end of the year. Known as the relative age effect, this phenomenon is evident in a wide range of arenas, such as youth sport and academia, but had not been closely studied in American pro football.

UNIVERSITY PARK, Pa. -- An international team of scientists, led by Penn State researchers, have identified genes that may help farmers, especially ones in low- and middle-income countries, breed chickens that can resist one of the biggest disease threats facing poultry today.

In the study, the researchers found that a set of genes differentially expressed in two breeds of chickens can fight off, in varying degrees, Newcastle disease, a virus that hampers poultry production worldwide.

Researchers at the University of Iowa and the U.S. Geological Survey have found that data gathered from orbiting satellites can provide more accurate information on the impact of large earthquakes, which, in turn, can help provide more effective emergency response.
