The coconut oil-derived free fatty acid mixture -- lauric acid, capric acid and caprylic acid as well as their corresponding methyl esters -- provides strong repellency against blood-sucking insects.The compound showed strong repellency against mosquitoes when higher concentrations of coconut oil compounds were topically applied.Washington: Compounds derived from coconut oil are better than China solar pest killing lamp Manufacturers DEET at preventing disease transmission and discomfort associated with insect bites, according to a study.However, increasing regulations and growing public health concerns about synthetic repellents and insecticides like DEET have sparked interest in developing plant-based repellents that are more effective and longer lasting, they said.DEET was only 50 per cent effective against stable flies, while the coconut oil compound was more than 95 per cent effective, they said. Most currently available plant-based repellents work for only a short period, Zhu noted.

By encapsulating coconut fatty acids into a starch-based formula, field trials showed this all-natural formula could provide protection to cattle against stable flies for up to 96 hours or four days, researchers said.Coconut oil fatty acids also provided more than 90 per cent repellency against mosquitoes -- including Aedes aegypti, the mosquito that can transmit the Zika virus, according to Zhu.The study, published in the journal Scientific Reports, identified specific coconut oil fatty acids that have strong repellency and long-lasting effectiveness against multiple insects -- mosquitoes, ticks, biting flies and bed bugs -- that can transmit diseases to humans and animals..Some people refuse to use DEET and turn to folk remedies or plant-based repellents.Against bed bugs and ticks, DEET lost its effectiveness after about three days, while the coconut oil compound lasted for about two weeks.

These coconut oil-derived compounds offer longer-lasting protection than any other known natural repellent against insect blood-feeding, Zhu said. the study found.For more than 60 years, DEET has been considered the gold standard in insect repellents -- the most effective and long-lasting available commercially, said researchers from US Department of Agriculture (USDA).A team of scientists led by Junwei Zhu found that the coconut oil compounds were effective against biting flies and bed bugs for two weeks and had lasting repellency against ticks for at least one week in laboratory tests.

"To send a probe where you haven’t been before is ambitious. It has been outfitted with a heat shield designed to keep its instruments at a tolerable 85 degrees Fahrenheit (29 degrees Celsius) even as the spacecraft faces temperatures reaching nearly 2,500 degrees Fahrenheit (1,370 degrees Celsius) at its closest pass.8 million miles (6.The corona gives rise to the solar wind, a continuous flow of charged particles that permeates the solar system.The probe is set to use seven Venus flybys over nearly seven years to steadily reduce its orbit around the Sun, using instruments designed to image the solar wind and study electric and magnetic fields, coronal plasma and energetic particles.

Unpredictable solar winds cause disturbances in our planet’s magnetic field and can play havoc with communications technology on Earth.The Parker Solar Probe, a robotic spacecraft the size of a small car, is slated to launch from Cape Canaveral in Florida, with August 6 targeted as the launch date for the planned seven-year mission.5 billion price tag, is the first major mission under NASA’s Living With a Star program.. By way of comparison, the average distance from the Sun for Earth is 93 million miles (150 million km). "In the most extreme cases of these space weather events, it can actually affect our power grids here on Earth."The project, with a . To send it into such brutal conditions is highly ambitious," Nicola Fox, a project scientist from the Johns China solar insect killing lamp Manufacturers Hopkins University Applied Physics Laboratory, told a news conference on Friday. NASA hopes the findings will enable scientists to forecast changes in Earth’s space environment. It is set to fly into the Sun’s corona within 3."It’s of fundamental importance for us to be able to predict this space weather, much like we predict weather here on Earth," said Alex Young, a solar scientist at NASA’s Goddard Space Flight Center in Maryland.

The previous closest pass to the Sun was by a probe called Helios 2, which in 1976 came within 27 million miles (43 million km).NASA is preparing to send a probe closer to the Sun than any other spacecraft has ventured, enduring wicked heat while zooming through the solar corona to study this outermost part of the stellar atmosphere that gives rise to the solar wind.The probe, named after American solar astrophysicist Eugene Newman Parker, will have to survive difficult heat and radiation conditions. NASA aims to collect data about the inner workings of the highly magnetized corona.1 million km) from the solar surface, seven times closer than any other spacecraft.
