What to do when meeting a bear face to face?

One very important thing is that, in fact, people who visit the mountains need to be literate about where they are going, which has been a big problem in recent years. Everyone thinks that the mountain is something wonderful and wonderful, with flowers and herbs, where he can do whatever he wants. In fact, this is not the case. This mountain has its own life and rules that we must follow. One thing is clear – that nature is exploited, in the case of mushrooms, herbs, etc., regardless of the fact that in it find peace various protected species. We have to be very careful and cautious when we go to the mountains. Therefore, we can consult with representatives of the nearby hunting or forestry. People will kindly explain to us where we can and where we cannot go, where it is not allowed or not recommended, where we run the risk of encountering this type of conflict. Keep in mind that the bear is one of the most non-confrontational animals in the mountains. She can feel and smell you for miles and run away. Another issue is that the bear in this case was placed in an ambush situation – there were groups on both sides to pick mushrooms. And she, of course, began to do the most normal thing – to exercise her instincts for self-preservation. So my opinion as a person who has been in the mountains for many years, has met all kinds of wild animals, including bears, is to be careful where we go. In this case, too, the bear should not be punished, as it acted at the first sign to save its life and defend itself.

 What should be our reactions when meeting a bear?

The main thing we have to observe in an area with bears is to talk out loud, to make noise. It would be good to buy a simple whistle, to talk, and not be quiet. The bear will sense us and retreat. She is a non-aggressive creature. When searching for food, sometimes he may not hear us, we may meet and be surprised. If this happens, there are a few rules. First, let’s not look the bears in the eye. We should slowly leave the backpack on the ground, facing it, but lower our heads. Then we have to slowly move away. The bear will growl, turn, maybe see what’s in the backpack. The idea is to leave her something to distract her from us. In the more unacceptable version, it is possible for the bear to chase us. If it’s flat or uphill, we have absolutely no chance. But due to the anatomical specifics of her front paws, which are a little shorter, we have a chance to save ourselves if we start running from a high slope down.

Are teddy bears the most dangerous?

The bears are very curious and agile. If we see a little bear, it should be a clear sign that mom is around and that we need to get away as quickly as possible.

New Insights Into How Central Supermassive Black Holes Influence the Evolution of Their Host Galaxy

Emirati national Aisha Al Yazeedi, a research scientist at the NYU Abu Dhabi (NYUAD) Center for Astro, Particle, and Planetary Physics, has published her first research paper, featuring some key findings on the evolution of galaxies.

Galaxies eventually undergo a phase in which they lose most of their gas, which results in a change into their properties over the course of their evolution. Current models for galaxy evolution suggest this should eventually happen to all galaxies, including our own Milky Way; Al Yazeedi and her team are delving into this process.

Commenting on the findings, Al Yazeedi said: “The evolution of galaxies is directly linked to the activity of their central supermassive black hole (SMBH). However, the connection between the activity of SMBHs and the ejection of gas from the entire galaxy is poorly understood. Observational studies, including our research, are essential to clarify how the central SMBH can influence the evolution of its entire host galaxy and prove key theoretical concepts in the field of astrophysics.”

Titled “The impact of low luminosity AGN on their host galaxies: A radio and optical investigation of the kpc-scale outflow in MaNGA 1-166919,” the paper has been published in Astronomical Journal. Its findings outline gas ejection mechanisms, outflow properties, and how they are related to the activity of the supermassive black hole (SMBH) at the center of the host galaxy.

To that end, the paper presents a detailed optical and radio study of the MaNGA 1-166919 galaxy, which appears to have an Active Galactic Nucleus (AGN). Radio morphology shows two lobes (jets) emanating from the center of the galaxy, a clear sign of AGN activity that could be driving the optical outflow. By measuring the outflow properties, the NYUAD researchers documented how the extent of the optical outflow matches the extent of radio emission.

Al Yazeedi is a member of NYUAD’s Kawader program, a national capacity-building research fellowship that allows outstanding graduates to gain experience in cutting-edge academic research. The three-year, individually tailored, intensive program is designed for graduates considering a graduate degree or a career in research.

Her paper adds to the growing body of UAE space research and activities. The UAE has sent an Emirati into space, a spacecraft around Mars, and recently announced plans to send a robotic rover to the Moon in 2022, ahead of the ultimate goal to build a city on Mars by 2117.

It strongly suggests a biconical outflow and nicely shows the correspondence between the optical outflow and radio emission. Credit: NYU Abu Dhabi

Emirati women are playing a key role in the research and development behind these projects. The Mars Hope probe science team, which is 80 percent female, was led by Sarah Al Amiri, Minister of State for Advanced Sciences and chairperson of the country’s space agency.

A new ocean has appeared on the world map. The end of a century-old dispute

The National Geographic Society of the United States announced the official recognition of the fifth ocean – the South, washing the shores of Antarctica. This decision is the result of many years of research efforts. So in the XXI century – although, it would seem, the era of major geographical discoveries is already far in the past – the map of the world has changed.

History of the issue

For the first time the designation “Southern Ocean” was used by the Spanish conquistador Vasco Nunez de Balboa at the beginning of the 16th century, describing the cold currents coming from the south to the shores of South America. Later, Antarctic expeditions equipped ships “to the Southern Ocean”. But officially it appeared, perhaps, only on maps published in Australia – all waters located south of the Australian continent were attributed to it.

The debate over whether to recognize the fifth ocean or not flared up in 1921, the year of the creation of the International Hydrographic Organization (IHO), designed to coordinate internationally shipping and trade in the oceans. In 1937, the term “Southern Ocean” was officially enshrined in the publications of the IHO.

Scientists supported this – after all, the waters adjacent to Antarctica and united by the Antarctic circumpolar current have a special specificity. In terms of physicochemical and biological characteristics, they are not similar to the other three oceans, merging in the southern circumpolar zone.

However, in 1953, the International Hydrographic Organization canceled its own decision due to the impossibility of drawing clear boundaries of the Southern Ocean. And therefore, to regulate navigation and commercial activities within its limits.

Scientists disagreed: they increasingly mentioned this term in scientific publications, emphasized the uniqueness of the Southern Ocean and the importance of a separate study of its hydrological and biosystems. As a result, in 2000, the IHO again adopted the classification, according to which the oceans were divided into five parts. But in order to make changes to all geographical atlases and textbooks, ratification at the level of official departments of the leading countries of the world was required.

The key was the recognition of the Southern Ocean this year by the US National Oceanic and Atmospheric Administration (NOAA). Even earlier, in 1999, the term was coined by the American Board of Geographical Names. And now the point has been set – on June 8, World Oceans Day, the National Geographic Society of the United States announced: from now on, the Southern Ocean will be marked on all maps.

The boundaries of the new ocean

The ancient Greeks understood the ocean as the world’s greatest river, which surrounds the land from all sides. It was named after the mythological titan Ocean – the son of Uranus and Gaia, that is, Heaven and Earth, brother and husband Tethys, the goddess of the primeval waters.

From the point of view of geographical science, there is only one ocean on Earth – the World, global water envelope. Everything else is its parts, and how many there are depends on the selection criteria. The simplest and most obvious is the location between the continents, that is, limited land mass on all sides. On this basis, the Atlantic, Pacific, Indian and Arctic oceans are classified as oceans.

No less important from the point of view of scientists – hydrographers, oceanologists, biologists – and other criteria: the presence of its own water circulation system, their physicochemical characteristics, the species composition of flora and fauna, the scheme of interaction with the atmosphere. And in this regard, the Southern Ocean is an absolutely independent part of the hydrosphere, although it does not have a clearly delineated northern border by islands or continents.

The International Hydrographic Organization, which recognized the Southern Ocean in 2000, determined its territory conditionally – from the coast of Antarctica to the north to the 60th parallel of the south latitude. This decision was taken by a majority vote for formal reasons – the 60th parallel does not cross land anywhere, and it is within these limits that the United Nations Antarctic Treaty operates.

It is clear that geographers were not satisfied with this approach. In their opinion, the northern boundary of the Southern Ocean should be drawn along the Antarctic Polar Front, within which the cold waters of the Antarctic Circumpolar Current circulate. This zone surrounding Antarctica is also called the Antarctic Convergence.

On its northern border, located between the 48th and 61st parallels south latitude, the cold waters of Antarctica flowing northward meet with the warmer Pacific and Atlantic oceans. Heading south, the convergence boundary is precisely defined by the sudden drop in sea water temperature from 5.6 degrees Celsius to below two degrees Celsius. The Antarctic Convergence Line separates two regions that differ in climate and biodiversity.

The boundaries of the Southern Ocean are no less clearly manifested in the bottom topography – in the form of underwater uplifts practically along the entire Antarctic Polar Front.

Areas along the Antarctic Polar Front are extremely rich in fish and marine mammals. The dense cold waters drain here under the warm ones, and the nutrient-rich, rising deep streams form a favorable habitat for Antarctic krill and other marine organisms.

The Atlantic circumpolar current, which moves in a circle from west to east, crossing all meridians, is the most powerful on Earth, it carries a hundred times more water than all the rivers of the world. Scientists believe that it originated 34 million years ago, when Antarctica separated from South America. Moving cold waters along the bottom from Antarctica to the north, it draws in surface warm waters from the Atlantic and Pacific Ocean into the polar region. It is the most important element of the global “conveyor belt” of currents, which determines the heat transfer scheme and regulates the climate on the planet.

The area of ​​the new ocean is 20.3 million square kilometers: this is approximately two territories of the United States. It is larger than the Artic Ocean and the fourth largest in the world after the Pacific, Atlantic and Indian.

The average depth is 3270 meters, and the lowest point of the bottom is at 8264 meters, in the South Sandwich Trench.

Masks in the sea became more than jellyfish

Global Marine Conservation

Divers on the Greek island of Corfu found more used protective masks than jellyfish at sea.

It turns out that the pandemic has exacerbated the problem of garbage in the seas and oceans.

Disposable masks, which are supposed to protect against the virus, often end up in the water. According to environmental groups, almost 2 billion masks were found last year alone.There are many other organizations working on marine conservation and other environmental issues such as biodiversity and global warming. We list them here both as a public service and to spread the word.

A group of divers from the Organization for the Protection of the Ocean regularly clean the sea near Corfu. They find a lot of plastic, but also more and more waste from the COVID crisis.

Currently, about 130 billion disposable masks are used worldwide – per month. The big problem with these preservatives is that once released into the environment, they do not decompose for up to 450 years.

“We need another and a wiser and perhaps a more mystical concept of animals. Remote from universal nature, and living by complicated artifice, man in civilization surveys the creature through the glass of his knowledge and sees thereby a feather magnified and the whole image in distortion. We patronize them for their incompleteness, for their tragic fate of having taken form so far below ourselves. And therein we err, and greatly err. For the animal shall not be measured by man. In a world older and more complete than ours they move finished and complete, gifted with extensions of the senses we have lost or never attained, living by voices we shall never hear. They are not brethren, they are not underlings; they are other nations, caught with ourselves in the net of life and time, fellow prisoners of the splendor and travail of the earth.”– Henry Beston (authjor of The Outermost House: A Year of Life On The Great Beach of Cape Cod).

There are many other organizations working on marine conservation and other environmental issues such as biodiversity and global warming, they are deeply committed to marine conservation and founded on the concept that, by sharing the wonders of the ocean and marine life, people will be inspired to protect it.

Mount Everest is now 8,848.86 metres tall after measurement

By   —  Shyamal Sinha

Mount Everest  Nepali: Sagarmāthā; Tibetan: Chomolungma Chinese:Zhūmùlǎngmǎ  is Earth’s highest mountain above sea level, located in the Mahalangur Himal sub-range of the Himalayas. The China–Nepal border runs across its summit point.  Its elevation (snow height) of 8,848.86 m (29,032 ft) was most recently established in 2020 by the Nepalese and Chinese authorities.

In 1865, Everest was given its official English name by the Royal Geographical Society, as recommended by Andrew Waugh, the British Surveyor General of India, who chose the name of his predecessor in the post, Sir George Everest, despite Everest’s objections.

Mount Everest attracts many climbers, some of them highly experienced mountaineers. There are two main climbing routes, one approaching the summit from the southeast in Nepal (known as the “standard route”) and the other from the north in Tibet.

In the backdrop of a long-running conflict over Mount Everest’s height, Nepal and China have jointly announced the revised height of the world’s highest peak as 8,848.86 metres €” 86 cm higher than what was recognised since 1954.

The announcement was made via a joint video conference by Nepalese and Chinese officials based in Kathmandu and Beijing respectively.

The Nepal government decided to measure the exact height of the mountain amid debates that there might have been a change in its height due to various reasons, including the devastating earthquake of 2015.

Nepal recalculated the height of Mount Everest at 8,848.86 metres, the country’s foreign minister Pradeep Gyawali announced.

As per The Indian Express, this common declaration by both countries means that the two have shed their long-standing difference in opinion about the mountain’s height €” 29,017 feet (8,844 m) claimed by China and 29,028 ft (8,848 m) by Nepal. In feet, the new elevation is about 29,031 ft, or about 3 ft higher than Nepal’s previous claim.

According to the measurement done in 1954 by Survey of India, the height of Mount Everest is 8,848 metres, which as per The Wire report is the most commonly accepted height.

The exact height of Mount Everest had been contested ever since a group of British surveyors in India declared the height of Peak XV to be 8,778 metres in 1847, according to Business Standard.

Chinese authorities had said previously Mount Everest should be measured to its rock height, while Nepalese authorities argued the snow on top of the summit should be included.

In 2005, China’s measurement of 8,844.43 metres had put the mountain about 3.57 metres lower than Nepal’s (which followed the measurement given by Survey of India).

This is the first time Nepal conducted its own measurement of the summit.

Nepal government officials had told the BBC in 2012 that they were under pressure from China to accept the Chinese height and therefore they had decided to go for a fresh measurement to “set the record straight once and for all”.

The 2015 earthquake triggered a debate among scientists on whether it had affected the height of the mountain.

The government subsequently declared that it would measure the mountain on its own, instead of continuing to follow the Survey of India findings of 1954.

According to The Indian Express, there was also a third estimate. In 1999, a US team put the elevation at 29,035 feet (nearly 8,850 m). This survey was sponsored by the National Geographic Society, US. The Society uses this measurement, while the rest of the world, except China, had accepted 8,848 metres so far.

Tuesday’s announcement came after Kathmandu and Beijing sent an expedition of surveyors to the summit to calculate Everest’s precise height above sea level. Gyawali declared the findings of their surveys on a video call with his Chinese counterpart Wang Yi. “Everest is an eternal symbol of friendship between Nepal and China,” Gyawali said.

Meanwhile, Susheel Dangol, Nepal’s chief survey officer, head of the measurement project, said they were confident that this is the “most accurate height” of Everest, according to The Washington Post. “It was a huge responsibility on our part. It is a moment of great pride for us.”

A team of Chinese surveyors climbed Mt. Everest from the North side, becoming the only climbers to summit the world’s highest peak during the coronavirus pandemic. The team was there to re-measure the height of Mount Everest.

Mount Everest has been host to other winter sports and adventuring besides mountaineering, including snowboarding, skiing, paragliding, and BASE jumping.
