ATTACK OF DRIVER ANTS

 In this clip from the BBC’s Natural World:                                                                                                     Ant Attack, we see central and east Africa’s powerful dorylus or driver ants hard at work. Watch as construction and ground workers begin to move up to 80 pounds of soil from the base of a fallen tree. It will become their new home in just a few days. Previous soil residents, beware! Plus, note how their sizes vary greatly, dependant on their role in the colony. A few fascinating facts: Seasonally, when food supplies become short, they leave the hill and form marching columns of up to 50,000,000 ants, which are considered a menace to people, though they can be easily avoided; a column can only ...

COVID-19 IN INDIA

Despite a strong response at the outset of the pandemic, as of Sept 22, India has the world's fastest growing outbreak of COVID-19 in absolute numbers according to WHO, reporting more than 5·6 million infections. Restrictions began to be lifted in June, and this relaxation has continued in the face of a continuing dramatic increase in case numbers nationally. Beneath these alarming national figures, the pattern of spread in India is nuanced and complex, with marked differences between states, and between rural and urban areas. For example, cities like Kolkata and rural areas in the north of India were relatively spared the outbreak initially, whereas Delhi, with strong international connections, was at the forefront of the first wave. Even so, India is clearly facing a dangerous period.
The country has responded well in many regards, especially for such a large and diverse nation. India instigated a national lockdown in March, which was praised by WHO. During the lockdown period, tertiary care provision was increased, including access to specialist equipment such as ventilators. Testing numbers also increased quickly, with India being among the first to roll out innovations like pooled testing. India has also been at the forefront of efforts to develop and manufacture a vaccine, both through domestic vaccine candidates and manufacturers such as the Serum Institute of India preparing production capacity for internationally developed vaccine candidates.

Difficulties remain. The lockdown created a parallel crisis for many people as income fell dramatically, hunger increased, and many migrant workers walked long distances home. India's GDP was already decreasing before COVID-19 but the contraction of almost 25% year on year in the quarter April to June could make India one of the worst affected countries economically. As the outbreak has spread from its initial foothold in cities to smaller urban areas and villages, pre-existing disparities in health-care provision have become increasingly relevant. Rural health infrastructure in India can be sparse, and some smaller private hospitals have reported equipment shortages, especially oxygen.
Most crucially, the rapidly growing case numbers, alongside the continuing relaxation of restrictions, are creating an atmosphere of fatalism mingled with false optimism that undermines effective use of non-pharmaceutical interventions such as masks and physical distancing. The epidemic in India is far from over, with a potentially huge burden of mortality and morbidity to come unless public health measures are used and adhered to. Without clear and honest communication of the risks of COVID-19 to the population, stemming the epidemic will be impossible.
According to news reports, hours before announcing the national lockdown, Prime Minister Narendra Modi told owners and editors from India's largest media organisations that it was important to tackle the spread of pessimism, negativity, and rumour. This pressure to avoid negative news, and to offer reassurance, appears to have been felt by several professional scientific organisations in India. The Indian Council of Medical Research (ICMR) has been singled out by experts for straying from scientific evidence, appearing at worst politically motivated and at best overly optimistic. A letter from the Director General of the ICMR, Balram Bhargava, said that the ICMR envisaged launching a coronavirus vaccine on Aug 15 (Indian Independence Day; a deadline considered unrealistic by most medical experts); ICMR has supported treatment with hydroxychloroquine despite insufficient evidence; and news reports claim that data on coronavirus infection were removed from a scientific paper.
Transparency of the data on COVID-19 cases and deaths, especially those underpinning the case fatality rate, has also been questioned, as detailed in a recent World Report. The Indian Government reports a case fatality rate of 1·8%, much lower than the reported rate in other countries, but it is difficult to know if the numbers are comparable.
Hope is important, and recognising successes is vital, especially during a pandemic. But presenting the current situation in India with a too positive spin not only clouds reality but also hampers vital public health initiatives. Perpetuating unrealistic claims or failing to honestly report negative news creates uncertainty among the public and health-care professionals, discouraging people from taking preventive action or taking public health messages seriously. India has the expertise in medicine, public health, research, and manufacturing to lead the nation through the COVID-19 pandemic. To capitalise on these attributes, the country's leaders must respect scientific evidence, expert commentary, and academic freedom, and not provide false optimism.

SELF DEVELOPMENT

With out a plan nobody can reach their destination.

A small social enterprise called Mera Guo Power (MGP) is trying to change things.They are putting two solar panels at a time. In just over a year, MGP has connected more than 3,500 customers to solar power mini grids at a village level Village by village, MGP is building : network of low cost solar microgrids that provide two LED lights and a mobile charging point to all paying house holds at a cost of twenty five rupees per week. That is cheaper than kerosene which can cost almost done across a month. Solar power, as a 'smokeless source of light, comes with added benefits customer health. Installing a microgrid is a grand event in the village and every one gets involved. In the village of Damdampurawa, the team maps the village house by house beneath the scorching mid-day sun, working out where to place each wire so as to connect custome...

STATUE OF UNITY

 Sure, numbers don’t lie but just numbers didn’t really give us an idea about how big the Statue of Unity really is. To understand their true meaning we had to feel them. We knew that the Statue of Unity, standing at 182 metres is now the world’s tallest statue. But not until we stood next to it, dwarfed even by the feet of the Iron Man of India, did we grasp the full enormity of this statue. Statue of Unity, Kevadia, Gujarat, India What is the Statue of Unity? The Statue of Unity is the statue of Sardar Vallabhai Patel. He is popularly referred to as the Iron Man of India. Post India’s independence in 1947, he played a pivotal role in bringing all the then-disjointed princely states into the Union of India. As a tribute to his towering personality, the statue, the tallest statue in the world, is rightly called the Statue of Unity. The enigma of this visit to the Statue of Unity starts with its story. In 2013 kits were sent to nearly 169000 villages of India to collect soil and iro...

HORMONES IN ANIMALS

  How are chemicals or stimuli used in animals as a serpent of instruction?  Take some animals like squirrels.  What does he experience when he is in a hostile situation?  He prepares his body to fight or to flee.  Both are very complex tasks that require a lot of energy to control.  Many different types of different tissues are used and their aggregated (aggregated) functions come together to function.  Like fighting or running, two alternating actions are very different from each other.  Thus, here is a condition in which some common preparations are beneficial to the body.  These preparations ideally facilitate any action in the near future.  How can all this happen?  If the squirrel's anatomy is based solely on electrical impulses through the neurons, the scope of the tissue ready to perform the next action will be limited.  On the other hand, if even a chemical signal could be sent, it could reach all the cells of the body...
