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.

Why schools ought to have 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.
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.
Better protection for endangered species
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.
Adam Peyman, Humane Society International
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.
Apples and tea to reduce the risk of cancer and heart disease
People who regularly consume moderate to high amounts of flavonoid-rich foods, such as fruits and tea, are less likely to die from cancer or heart disease, says an Australian-Danish study.
The beneficial effect of flavonoids on health has been observed particularly among people at high risk of having chronic diseases due to smoking or who consume more than two alcoholic beverages per day.
To arrive at this conclusion, Dr. Nicola Bondonno of the Edith Cowan University School of Medicine in Perth, Australia, and her colleagues analyzed data collected from a Danish cohort of 53,048 individuals whose eating habits have been listed for 23 years.
Our findings are important because they highlight the potential for preventing cancer and heart disease by encouraging the consumption of flavonoid-rich foods, particularly those who are at high risk of developing chronic diseases.
Dr. Nicola Bondonno
But it is also important to note that the consumption of flavonoids does not neutralize all the increased risks of death caused by smoking and high consumption of alcohol, said the researcher.
The best thing to do for your health is to stop smoking and reduce your alcohol intake.
Dr. Nicola Bondonno
“These lifestyle habits are very difficult to change. Encouraging the consumption of flavonoids may be one way to reduce the increased risk, particularly if it is associated with pushing people to quit and reduce their alcohol consumption=,” Dr. Bondonno said.
- The flavonoids were discovered in 1936 by the Hungarian biochemist Albert Szent-Györgyi, Nobel Prize in Physiology in 1937, who also discovered vitamin C.
- Besides in fruits and vegetables like apples and broccoli, flavonoids are present in tea, red wine, dark chocolate, and honey.
- These are so-called polyphenolic compounds, known for their anti-inflammatory and antioxidant effects, and for those they have on heart health by keeping the arteries relaxed and preventing blood platelets from clumping together to form a clot.
How much to consume?
In the cohort, people who consumed about 500 mg of flavonoids a day had the lowest risk of dying from cancer or heart disease.
Researchers say it’s important to vary its consumption of flavonoid compounds found in a variety of plant-based foods and beverages.
For example, every day, drinking a cup of tea, eating an apple, an orange, 100 g of blueberries and 100 g of broccoli can exceed 500 mg of flavonoids.
Dr. Bondonno says that while research has established an association between flavonoid consumption and decreased risk of premature death, the exact nature of the protective effect is still unclear and could be broken down into several aspects.
Alcohol use and smoking increase inflammation and damage the blood vessels, which can increase the risk of suffering from various diseases.
Dr. Nicola Bondonno
However, the anti-inflammatory effect of flavonoids on blood vessels has already been demonstrated, and could be part of the explanation.
The authors of the study published in the journal Nature Communications (New Window) now want to try to establish which types of cancer or heart disease are most affected by the beneficial effects of flavonoids.
