There is no doubt that the use of pesticides to prevent insects from eating or otherwise destroying crop plants has led to huge yield gains in many places around the globe—but its heavy use has also caused negative side effects, such as runoff into the oceans causing dead spots. In this new effort, the researchers sought to learn whether the large amounts of pesticides used on farms are actually necessary to sustain yields. To find out, they accessed a database that held information on 946 non-organic arable commercial farms across France. The farms were part of the Dephy network, which was created as part of the government’s Ecophyto initiative to reduce pesticide use—the farms represented a wide range of farming techniques, which included using nonstandard amounts of pesticides, herbicides and fungicides—each of the farms submitted reports to the database administrators detailing chemical use on their farms, crop yields and other details of their operations.In studying reports generated by their analysis of the farms, the researchers found that 77 percent of the farms under study showed no conflict between using smaller amounts of pesticide and yield rates. They also found that the other 23 percent of the farms were generally associated with industrial farming, which is particularly dependent on high concentrations of pesticides to sustain yields. The researchers contend that their analysis also showed that approximately 59 percent of all farms in France could reduce their use of pesticides by approximately 42 percent without harming yields.

In their paper published in the journal Nature Plants, the team describes their study of hundreds of French farms where pesticide use was varied to find out how much was actually needed.

Meeting this challenge will necessarily imply a drastic reduction of adverse environmental effects arising from agricultural activities. The reduction of pesticide use is one of the critical drivers to preserve the environment and human health. Pesticide use could be reduced through the adoption of new production strategies; however, whether substantial reductions of pesticide use are possible without impacting crop productivity and profitability is debatable. Here, we demonstrated that low pesticide use rarely decreases productivity and profitability in arable farms. We analysed the potential conflicts between pesticide use and productivity or profitability with data from 946 non-organic arable commercial farms showing contrasting levels of pesticide use and covering a wide range of production situations in France. We failed to detect any conflict between low pesticide use and both high productivity and high profitability in 77% of the farms. We estimated that total pesticide use could be reduced by 42% without any negative effects on both productivity and profitability in 59% of farms from our national network. This corresponded to an average reduction of 37, 47 and 60% of herbicide, fungicide and insecticide use, respectively. The potential for reducing pesticide use appeared higher in farms with currently high pesticide use than in farms with low pesticide use. Our results demonstrate that pesticide reduction is already accessible to farmers in most production situations. This would imply profound changes in market organization and trade balance.

Darjeeling: Drones, trap cameras, cages and three days of search operations have failed to spot Sachin, the leopard. This has given rise to doubts whether Sachin is still at the premise of Bengal Safari Park.Sachin, an adult leopard had escaped from the leopard enclosure at Bengal Safari near Siliguri on Tuesday morning. The Safari authorities said clues suggested Sachin was hiding in the adjacent herbivore enclosure since his escape. More than a 100 forest personnel along with wildlife squads; four trained elephants and vehicles have been pressed into the search operations. Also Read – Rain batters Kolkata, cripples normal lifeAround 15 cages have been set up inside the 91-hectare herbivore enclosure and seven trap cameras have also been set up and drones flown on Thursday in search of Sachin. Vinod Kumar Yadav, Member Secretary of the West Bengal Zoo Authority on Thursday stated: “We have left no stone unturned. All resources are being utilised to the full capacity. Let us see what is the result.” However, most of the personnel of the wildlife squad are of the opinion that Sachin has gone out of the Safari Park. The minute search operation, drones and bursting of fire crackers throughout the day would definitely spotted the adult leopard, they feel.

They can even hide for hours in bushes,” argued Ashim Chaki, Assistant Director. Meanwhile, pug marks were seen on Thursday in the 7th Mile area adjacent to the Park. Though the marks are that of a leopard, it cannot be said for sure that it belongs to Sachin. Wildlife authorities feel that Sachin has lost the ability to hunt owing to his long tenure at Leopard Rescue Centre in South Khayerbari in Jalpaiguri. He used to be fed in the Park. Forest personnel also feel that owing to lack of food since escape, Sachin could have gone weak. On top of that not a single herbivore including deer have been attacked by Sachin. Sachin’s escape has taken a toll on the visitor footfall. Thursday saw diminishing numbers. As visitors have been prohibited to roam the park on foot, business in canteens and restaurants has been considerably affected. Meanwhile Sourav, the other male leopard is being closely watched. He has been shifted from the open space of the enclosure to the night shelter. In June 2018, two male leopards were brought to the Safari. The duo had been caught from Satali Tea Estate in Alipurduar and were kept at Leopard rescue Centre in South Khayerbari in Jalpaiguri.
Bosses, take note. You may receive considerably more blame for the negative consequences of your actions than an employee, according to a new study. Theories to date had assumed that praise and blame were determined by the extent to which an individual is able to exercise causal influence over something. “That means the reason why the boss is criticised more severely than the employee is because it was he who made the decision and, therefore, his causal influence over the situation was more significant,” said Kai Kaspar from the University of Cologne in Germany.

Also Read – Over 2 hours screen time daily will make your kids impulsiveOn the other hand, an employee receives significantly more praise if his actions result in positive consequences than his superior, the findings showed.According to this theory, his social role as the boss is irrelevant.To test this assumption, the team conducted an online study with 209 test participants.The participants were asked to state their position on the following situation: rather than the boss, an employee makes an important decision in the company. Both employee and boss are aware that, while the decision is in the best interest of the enterprise, it will have a negative impact on the environment as a side-effect. Both explicitly state that they do not care about this side-effect.In the experiment, the boss received more criticism than the employee, even though he did not personally make the decision. “We now have ample reason to assume that the social function plays a significant role in determining how much praise or criticism we allocate to a person for any negative consequences of their actions,” the researchers explained.
Older adults with mild cognitive impairment (MCI) who indulge in exergames – video games that are also a form of exercise – may experience significant improvement in complex thinking and memory skills, according to a study. Exergaming relies on technology that tracks body movement or reaction. The study, published in the journal Frontiers in Aging Neuroscience, showed that exergames may slow the debilitating effects of those with MCI, that is often a precursor to Alzheimer’s. Also Read – Add new books to your shelf”Exergaming is one more thing that could be added to the arsenal of tools to fight back against this cruel disease,” said lead author Cay Anderson-Hanley from Union College in New York, US. “The results suggest that the best outcome for brain health may result when we do both: move it and use it,” Hanley added.The study included more than 100 seniors, with an average age of 78, who were divided into two groups. One group was assigned to pedal along a scenic virtual reality bike path several times a week where another group had to pedal while playing a video game. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe data were then compared against data collected from a separate group who played video games on a laptop but did not pedal, and also a group from the previous research who only rode a traditional stationary bike with no gaming component.The results showed that participants in both the group experienced significantly better executive function, which controls, in part, multi-tasking and decision making. Benefits were also observed for verbal memory and physical function.
Vellore Institute of Technology, one of India’s premier private higher educational institutions has been in the forefront for extending help to all those sections who belong to the downtrodden and underprivileged sections. It has also mobilised resources and financial assistance to people who have been severely affected by natural calamities.Towards rescue and rehabilitation efforts of the Tamil Nadu government, and to help victims affected by Gaja Cyclone, especially in the coastal and central districts of the State, the VIT has extended a financial assistance of Rs 1.25 crore to the Chief Minister’s relief Fund. A cheque was personally handed over to the Chief Minister Edappadi K Palaniswami by Dr G Viswanathan, Founder and Chancellor of VIT, recently. The amount has been mobilised from students, parents, staff and non-teaching staff who have given a portion of their salary as a contribution from the management of VIT. Dr Sekar Viswanathan, Sankar Viswanathan and G V Selvam, Vice Presidents of VIT were also present on the occasion. It may be recalled that during the massive damage caused by the floods in Kerala a few months ago, VIT mobilised relief materials worth Rs 24 lakh. VIT also gave Rs 1 crore as relief amount with Dr Viswanathan handing over a cheque personally to Kerala Chief Minister Pinarayi Vijayan.
