Creation of ‘Death Clouds’ of Fungal Spores Killing Gypsy Moths

07 Sep 17

A new Cornell study stated that a fungus can kill the populations of gypsy moths. It has the capacity to create ‘death clouds’ of spores which can travel for more than 40 miles. The death clouds of spores can potentially infect populations of invasive moths.

The forest trees especially oak and aspen were under danger due to gypsy moth (Lymantria dispar) caterpillars. The caterpillars used to eat the leaves of these trees and thus used to decimate the forests, orchards and properties across the northeastern United States. Gypsy moth caterpillars almost ate the leaves off 350,000 acres of forest plants in the year 2016 in the Massachusetts. This study was published online in the journal August 2017 in the Applied and Environmental Microbiology. The journal described a new method for tracing the geographic range of this fungus which is airborne insect pathogen. It was conducted in the areas of disease outbreak.

“Oumuamua” a New Visitor to Solar System

18 Dec 17

Our Solar system is full of surprises and shocks. Our solar system has a visitor. A new research has revealed that an object that is cylindrical shaped, dark in appearance and reddish in color, and that is almost a quarter-mile long, is coming towards our solar system.

It is also true that this object is not going to stay here. This object came blazing into our galaxy with the speeds of up to 196,000 mph. it is a very strange object and its amazingly fast speed reflects that it has not been originated from within our solar system any way. It is first of its kind that was observed by humans. Scientists used Pan-STARRS 1 telescope to discover that. The strange object has been named “Oumuamua’ that means messenger. Various speculations are being made about its identity. Some scientists are guessing that it can be an artificial object that it is a spaceship, which was monitored by a remote. It has been announced by the scientists this week that radio telescope will probe 'Oumuamua for signs of technology. Unlike other Planets and asteroids, Oumuamua immersed into our solar system from outside the plane. Its size is also very strange, unlike other asteroids. It is basically a lifeless rock. The most suitable radio telescope in for conducting these types of observations is the “Green Bank.”

The Harm of Chemical Fertilizers

16 Dec 17

Would you like it if we ingested your body with chemicals every now and then? So why do the same to plants. Using chemical fertilizers as nutrient source to boost the plant growth is not a healthy way to treat the soil and the plants. We are seeing a massive use of chemical fertilizers in the third world countries to cater to the extra food requirement.

This over use of chemical fertilizers is leading to a number of environmental issues and health problems among the humans. This also causes a permanent damage to the soil in the area where it is used and leaves it unfit to grow crops after a point of time.

The need of the hour is to shift the system from chemical to organic to not just maintain and improve the soil quality but also reduce the harm that it is causing to us.

Ever Heard of Laissez – Faire Leadership?

15 Dec 17

The Laissez – faire leadership is also known as delegate leadership style. It is a type of leadership style in which leaders do not interfere and allow group members to make decisions. Researchers have studied that this style of leadership leads to the lowest productivity among group members. Still, one has to understand both benefits and pitfalls of such leadership style.

This style works excellent when the team members have skills to succeed. The team members are able to deal with any issue through their expert skills. Laissez – Faire is a style which allows team members to feel free and stay satisfied with their work. Thus, independence is valued and followers have a high – level of passion and intrinsic motivation towards their work. The downsides of Laissez – Faire leadership can sometimes prove to be very dangerous. It is not ideal when group members lack knowledge or experience. It can lead to low accountability, passivity and avoidance. Therefore, use this kind of leadership wisely to ensure growth of anything.

Climate Migration Demands International Attention

14 Dec 17

Climate Change is a human rights issue. In 2016, extreme weather, climate conditions displaced approximately 45 people every minute. This issue is in immediate need of action. As a result, civil leaders from more than 100 countries across the world, have urged for an action on the displacement caused due to climate change at a summit in Suva, Fiji. They suggested the international community to defend the human rights of the victims of such displacement.

Climate change should be identified as a major cause for migration in the global compact due to be negotiated by countries in 2018, such as Oxfam Pacific, 350.org and Act Alliance. Certain instances of climate migration are (i) sea level rise in the pacific, making some island communities unviable; (ii) 2 kilometres inland movement of Vunidogoloa in Fiji, in 2014, leading to relocation of 30 villages. There are well framed international rules for giving asylum to victims of political persecution but no provision for people displaced by climate change. It has been seen that initiatives in this regard have been made by New Zealand, due to its longstanding relationship with a number of Pacific islands. It is planning to create world’s first humanitarian visas. These visas shall be employed towards people displaced due to climate changes. There is need for other countries also to enforce such actions. But in reality, only vulnerable countries are eager to discuss the subject during climate negotiations, others often focus on different priorities.
