Better protection for endangered species

Published

on

Political leaders and conservation experts gather for a summit in Switzerland to agree on stronger measures to protect giraffes and elephants against international trade, just months after an alarming report on the state of species at risk.

Up to a million plant and animal species are threatened with extinction and the pace is accelerating, warned the United Nations in May.

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which brings together thousands of delegates from more than 180 countries, opened on Saturday.

A total of 56 proposals to change the level of protection afforded to wild animals and plants will be debated by August 28.

Already, delegates have agreed to regulate the international trade in giraffes, to protect this large mammal threatened with a “silent extinction” .

The number of giraffes in Africa has decreased by about 40% in 30 years. There are fewer than 100,000 animals today, according to the International Union for the Conservation of Nature.

From now on, trade in skin, horns, hooves and giraffe bones would be considered a threat to the survival of the species.

The measure was applauded by environmentalists.

Granting this protection to giraffes is a vital lifeline for this majestic species, which had been slowly dying out for years.

However, not all delegates agreed on the real threat to giraffes, with some pointing out that the loss of habitat due to human activities remains more of a concern than trade.

And hunting trophies?

The agreement for the preservation of giraffes also includes a measure to further control the legal trade in items derived from them, including trophies reported by hunters.

Nature organizations and MEPs are calling for these trophies to be banned for all endangered animals.

Trophy hunting, which is recreational in nature and is considered “non-commercial”, is currently exempt from CITES prohibitions. The question is not on the agenda of the conference, however.

A large number of species are coveted by hunters, including elephants, black and white rhinos, crocodiles, gray parrots and cheetahs.

The United States is the largest importer of hunting trophies, followed by China.

Zoos will not be able to buy elephants anymore

In the meantime, delegates in Geneva also reached an agreement to ban the sale of wild elephants to zoos.

The countries of West, Central and Eastern Africa already prohibit sending these pachyderms into zoos, unlike in southern Africa, where they are less threatened.

More than 100 baby elephants have been sold to Chinese zoos by Zimbabwe since 2012, according to the Humane Society International.

It would be banned from now on. The sale of elephants is therefore limited only to the maintenance of these animals in their natural environment, in particular reserves.

This decision will save a large number of elephants torn from their families in the wild and forced to spend their lives imprisoned in zoos in mediocre conditions.

Iris Ho, from the Humane Society International

Ecologists have called the measure a “historic victory”.

All approved proposals for debate, including those on giraffes and elephants, will have to be confirmed in plenary at the closing meeting of the CITES conference on 28 August before officially entering into force.

The government of India felicitates scientists who have contributed immensely in the field of science to mark the anniversary of India’s greatest discovery- ‘Raman effect’.

Who was CV Raman?

Dr CV Raman was a renowned scientist who had a bachelors’ and masters’ in Physics from the Presidency College in Madras. He took part in numerous science competitions along with the government job. Afterward, he received a scholarship from the Indian government

28th February is celebrated as National Science Day (NSD) in India. NSD is celebrated to commemorate discovery of the ‘Raman Effect’, which led to Sir C.V. Raman winning the Noble Prize.

When was the day declared National Science Day?

In 1986, the National Council for Science and Technology Communication (NCSTC) asked the Government of India to designate 28 February as National Science Day which the then Govt. of India accepted and declared the day as National Science Day in 1986. The first National Science Day was celebrated on February 28, 1987.

What is Raman Effect?

Raman Effect is a phenomenon in spectroscopy discovered by the eminent physicist Sir Chandrasekhara Venkata Raman in 1928.  After two years in 1930, he got Nobel Prize for this remarkable discovery and this was the first Nobel Prize for India in the field of Science. while working in the laboratory of the Indian Association for the Cultivation of Science, Kolkata.


The Raman effect is also known as Raman scattering. In this, the wavelength of the light scatters when the light is reflected on a particular object. The Raman effect was discovered in the 19th century and was named after the great scientist CV Raman. The prominent scientist was also awarded the Nobel prize for his discovery in the year 1930.

Raman Effect is a change in the wavelength of light that occurs when a light beam is deflected by molecules. When a beam of light traverses a dust-free, transparent sample of a chemical compound, a small fraction of the light emerges in directions other than that of the incident (incoming) beam. Most of this scattered light is of unchanged wavelength. A small part, however, has wavelengths different from that of the incident light; its presence is a result of the Raman Effect.

NSD 2021

The theme of NSD-2020 is “Future of science technology and innovation (STI): Impacts on Education, Skills, and Work”.

National Council for Science & Technology Communication (NCSTC) of Department of Science & Technology (DST) is nodal agency to support catalyze and coordinate celebration of the NSD throughout the country, particularly in scientific institutions & research laboratories.

NCSTC has supported various programmes countrywide by supporting its State S&T Councils & Departments for organization of lectures, quizzes, open houses, etc.

National Awards

DST instituted National Awards in 1987 to stimulate, encourage and recognize outstanding efforts in the area of science popularization and communication and in promoting scientific temper.

The  National S&T Communication Awards, Augmenting Writing Skills for Articulating Research (AWSAR) awards, and SERB Women Excellence Awards and  Rajendra Prabhu Memorial Appreciation Shield for outstanding work in science media and journalism were conferred on NSD 2021.

science laboratory equipment

Laboratory equipment; In this article, we are going to discuss why the schools must have laboratory equipment and how significant these are for the students.

Different subjects have taken up by the students and Science is a unique one. This is distinct from other subjects that a student takes up in school. This discipline affects the life of people in several ways. From the local weather forecast to the food that we eat daily and from the simple electronic gadgets that we are using in our day to day lives to handle the complex machines as well as systems, and the science is everywhere. The science includes seeing, understanding, operating, and manipulating real objects and other materials.

Laboratory equipment

It requires a different approach to teach science. Schools offer various types of opportunities both theoretical as well as practical to their students through various methodologies and processes. It has observed that the educational institutions that provide the combination of classroom and textbook studies along with science lab experiments can derive the best results for the students. So, the science labs and science laboratory equipment assist in developing scientific learning amongst students and in generating the deeper as well as profound interest in this field.

This is important because the knowledge acquired from classrooms and via books is incompetent without any understanding and learning the methodologies and procedures behind the same. This science laboratory equipment allows you to utilize the data gathered from the books and the material globe for growing logic and rationale. Students have to use various tools and do experiment with the different techniques to make improvements in their overall science literacy.

Apart from offering a handy experience, these laboratory equipment’s teach students how to make a scientific argument. It provides some of the valuable and vital skills to the students such as conducting experiments, review closely, responding to analytical comments, and enhancing the logical reasoning that will assist the next generation of professionals such as engineers, medical professionals, and scientists.

Moreover, these school laboratory equipment play an enormous role in the advancements and technologies in the world. Most of the famous scientists as well as researchers across the world develop their interest in science during their school lab while experimenting. Therefore, schools must invest in up to date laboratory equipment with high quality to generate great scientists and researchers by developing their interest and produce skilled as well as a competent labor force. It also offers a great future to the medical sciences and developments in technology.

Schools and colleges have to buy lab supplies and laboratory equipment of different types such as physics laboratory equipment, physics lab equipment, anatomy model, biology lab equipment, and so on.

The significance of advanced science laboratory equipment in school labs

Schools need to have the latest and top-notch quality of laboratory equipment for their science students these days. Science is different from any other subject and to understand this, one has to do all the concepts practically as theoretical knowledge is not enough. Effective teaching methods and learning include handling, manipulating, and seeing new objects as well as materials. The knowledge that a student has gained from the classroom study is of use if they do not observe the process and understand the connection between the action and reaction.

The teaching approach of science includes a frequent situation of the show and tell. Good schools use a blend of classroom teaching with that of laboratory equipment to makes rue that their students grab every concept in-depth. It has also observed that teaching and learning in a laboratory that is conducted to develop practical knowledge of a student will be of utmost use to encourage learners in getting a deep understanding of all concepts. Pupils can notice and grasp the knowledge for longer if they observe the experiment in front of their eyes.

Such laboratory equipment enables learners to interact straightly with the data collected. They acquire first-hand experience by performing all the experiments in real-time on their own. Students use all models and get to know how to use the theories and concepts of science practically. It has also found that this laboratory equipment’s made it easy for both teachers and pupils to grab the knowledge and review it properly. These theories and concepts of science are hard to explain and understand through these books. Anatomy models, chemistry science kits, and physics science kits are the best ways to get a better understanding and in an easy manner.

To encapsulate, it is a must to have laboratory equipment in school to make science more interesting and help the students to develop a better understanding. They have a huge contribution in the field of physics, chemistry, and biology in later life.

A monstrous planet that should not exist

Published

on

An exoplanet is different from what astronomers have discovered so far. This is Kepler 10C. It’s so special, it should not exist!

The Kepler 10 system has been known for a few years. It is a planetary system whose star is strangely similar to our sun, despite being twice as old. The third planet closest to this star, the 10C, is attracting the attention of scientists for a good reason. It should not exist!

According to the theory currently accepted in the scientific community in astrophysics, there are two types of planets: rocky or gaseous. The telluric type, so rocky, corresponds to a certain mass. But in the case of Kepler 10C, it is large, 2.3 times the diameter of our Earth, but much too massive: 17 times the land mass. This break problem, since this exoplanet should be gaseous and not rocky.

Astrophysicists believe that the mass of this planet is such that it would normally have formed a gigantic atmosphere and become a gaseous giant because of its gravitational force. Another amazing fact: this planetary system is 11 billion years old. This means that the birth of Kepler 10C took place only 3 billion years after the Big Bang. Heavy elements were present in the universe sooner than scientists believed.
