Dippy the dinosaur, makes way for a blue whale at London’s Natural History Museum

Dippy the dinosaur, makes way for a blue whale at London’s Natural History Museum

Hope, the blue whale, became the head of Dippy the dinosaur, as the centerpiece of the renovated Natural History Museum atrium on Thursday despite an energetic campaign to keep the attraction dear.

Replication of the skeleton was in the museum for more than 100 years and the news of its impending demise in 2015 provoked the condemnation of dinosaur fans who send #savedippy hashtag tendencies on Twitter. About 14 000 people have signed a petition to stop the movement.

However, the museum said that the skeleton of a blue whale, the largest animal they have ever lived on Earth – which was hunted near extinction – to raise awareness about the impact of humanity on nature.

The actual skeleton of 25.2 meters (83 feet) suspended from the ceiling “is a powerful reminder of the fragility of life and responsibility towards our planet,” said Michael Dixon, director of the museum.

The whale was previously mammals section, but was not entirely in order and will now have a central place in the burial place of diving in Hintze Hall, a cathedral space built in the late 19th century.

Dippy fans do not need desperation because the replica is placed in any case preserved for posterity in a bronze mold outside the museum.

The wife of Prince William, Kate, Duchess of Cambridge, attended a gala launching of the Hope reception on July 13 with the famous British Conservative David Attenborough.

An estimated 2,50,000 blue whales in the world’s oceans in the 1800s, but commercial hunting brought the species to the brink of extinction in 1960 with only 400 samples remaining. The legal protection of the hunt saw their levels increase to 20,000 now.

‘Sixth extinction’ of wildlife faster than feared

'Sixth extinction' of wildlife faster than feared

‘Sixth extinction’ of wildlife faster than feared

The sixth mass extinction of life on Earth is developing faster than previously feared, scientists warned.

Over 30% of animals with a backbone – fish, birds, amphibians, reptiles and mammals – are declining in both the range and population, according to the first comprehensive analysis of these trends.

“This is the case of a biological annihilation occurring globally,” said Stanford professor Rodolfo Dirzo, a co-author of a study published Monday in the US journal Proceedings of the National Academy of Sciences.

About a decade ago, experts feared a new planetary extinction of species would be in sight.

Today, most agree that it is under way, but the new study suggests that death is already increasing.

It provides much needed data on the threat to wildlife, mapping the decline in ranges and populations of 27,600 species. For 177 mammals, the researchers collected data covering the period 1900-2015.

The mammal species that were monitored have lost at least a third of their original habitat, the researchers found.

Forty percent of them – including rhinoceros, orangutans, gorillas and many large cats – survive on 20% or less of the land they once wandered.

Biodiversity loss has accelerated recently.

“Several species of mammals that were relatively safe one or two decades ago are now in danger,” including cheetahs, lions and giraffes, the study showed.

Around the world, mass death, considered the sixth in the last 500 million years, is the worst since three-quarters of life on Earth, including non-avian dinosaurs, was annihilated 66 million years ago By a giant Impact of meteors.

On average, two species of vertebrates disappear each year.

Tropical regions have recorded the highest number of declining species. In South and Southeast Asia, large-bodied mammal species have lost more than four-fifths of their historical ranks.

Loss of habitat

While fewer species are disappearing in temperate zones, the percentage is as high or higher.

Up to half the number of animals that once shared our planet are no longer here, a loss that the authors described as “a massive erosion of the greatest biological diversity in Earth’s history.”

There is no mystery as to why: our own constantly expanding species – which has more than doubled in number since 1960 to 7.4 million – is eating, crowding and polluting its planetary peers of existence.

By comparison, only 20,000 lions remain, less than 7,000 cheetahs, 500-1,000 giant pandas and about 250 rhinos in Sumatra.

The main causes of declining wildlife are loss of habitat, over consumption, pollution, invasive species, disease, and poaching in the case of tigers, elephants, rhinos and other large animals appreciated for their body parts.

Climate change is poised to become a major threat in the coming decades, with some animals – the most famous polar bears – already declining due to rising temperatures and changing weather patterns.

“The massive loss of populations and species reflects our lack of empathy with all the wild species that have been our partners since our origins,” said lead author Gerardo Ceballos of the National Autonomous University of Mexico.

The Storied History of the Spooky Physics Behind China’s Teleportation Success

The Storied History of the Spooky Physics Behind China’s Teleportation Success

The Storied History of the Spooky Physics Behind China’s Teleportation Success

In June 2017, a group of scientists in China announced that they had used the Micius satellite the country, launched a year ago, to teleport information between Earth and space in an instant. In other words, they moved more than 500 km at any time.

For this, they were based on a natural phenomenon known as quantum entanglement. The name itself suggests that it belongs properly to the realm of quantum mechanics, the field of subatomic particles.

The experience of Chinese scientists has surpassed the previous record, when in 2012 its leader had carried a team that had teleportation more than 97 km.

Very few ideas in science enjoy the popularity of teleportation: it was so incredible among scientists and laymen.

For more inspiration, what is fascinating is not how an object “leaves” a point in space and “passes” to another, but through the intermediate distance in an instant.

The consequences of these movements are important at first. The day we will be able to “pass” a person up and down through space – Star Trek – could still be far away, but, in the meantime, we could use quantum entanglement, for example, remote control of Digital security keys between two computers and prevent most forms of listening by hackers.

In previous experience, Jian-Wei Pan, professor of physics at the University of Science and Technology of China, Hefei, and his colleagues have used quantum entanglement to teleport information across Lake Qinghai in the west of the country.

Using an ultraviolet laser pointing at a barium crystal, the Pan equipment generates pairs of entangled photons. Each photon of a pair is transmitted using a telescope in two parts on both sides of the lake.

Making personalized photons gives a good overview of the situation in which photons are present. It refers to the values ​​of some fixed variables. If the variables have a particular combination of values, then the system is said to be in a particular state. United States are generally independent of extrinsic properties such as mass.

Therefore, the objectives of A and B are designed to see if the third interacting with these photons is in a similar state to the control group, even when they are separated by 97 km of space.

To measure this, researchers at A allow locally generated photons – that is, to themselves – to interact with altered incoming photons in a fixed and predictable way.

This state of change is then measured and compared to the state of the photons at B. Pan & Co. One found that the states of the modified A photons and those of the unmodified B photons were the same 80% of the time.

What is wonderful is that the particles do not have to end up with the same condition. Eighty percent is enough to rule out the coincidence.

This long-distance “communication” between the tiny and fragile particles shows that their pre-trip tangle was sustainable and gave rise to a predictable state that allows particles to behave similarly in both experiments to a very different extent.

NASA CAN’T AFFORD TO PUT HUMANS ON MARS

NASA CAN’T AFFORD TO PUT HUMANS ON MARS

The United States space agency has to land Mars on humans a priority of its exploration programs and the bipartisan legislation promised in 2010 to develop the ability to send humans to the planet by 2030.

But it remains a major problem between humanity and the red planet: money.

Emails and Alerts for Technology and Science – Get the Best of Newsweek Technology and Science Magazine Sent to Your Mailbox

The head of NASA’s space exploration program, William Gerstenmaier, said Wednesday that with its current budget, the agency simply can not afford the cost of propelling a spacecraft to Mars.

“On this horizon, in the 2030s, I can not put dates on humans on Mars,” Gerstenmaier said Wednesday in response to a question during a propulsion meeting of the American Institute of Aeronautics and Astronautics in Georgia.

“At the budget levels we have described, this is about an increase of about 2 percent, 100 that do not have surface systems available for March, this entry, landing and landing is a big challenge for us to Mars. ”

NASA landed several unmanned exploration vehicles on Mars in the past. The Curiosity rover, which landed at Marsh in August 2012 and will soon hold its fifth anniversary exploration of the planet, costs about $ 2.5 billion.
Gerstenmaier said an intelligent Mission to Mars would weigh about twenty times what previous Rover weighed. “So this is an increase of twenty times,” he said, which probably means a much higher cost.

Legislators attribute the NASA budget to $ 19.5 billion for fiscal year 2017, which is less than half of one percent of the total federal budget.

The agency did not give a specific figure for the cost of the manned mission to Mars, and estimates vary depending on the source. In 2012, the head of NASA’s Propulsion Laboratory Brent Sherwood, estimates that the project could cost up to $ 100 billion in 30 or 40 years.

Most recently, Pascal Lee, director of the Mars Institute, a nonprofit research group funded in part by NASA and based on a NASA research center in Silicon Valley, said in May that a human mission to March could cost up to $ 1 billion over 25 years.

Private organizations working on their own missions to Mars have estimated lower costs. Mars One, a Dutch-Swiss organization to establish a permanent settlement on Mars, plans to bring four people to March at a cost of $ 6 billion. SpaceX founder Elon Musk, who said he wanted to send humans to Mars in the early 2020s, estimated the cost at $ 10 billion per person by 2016.

Landing on Mars poses many threats to a manned mission. The spacecraft must tilt its entrance into the atmosphere of Mars correctly: if it is too rigid, the machine can burn, and if it is too low, the machine can completely lose the planet.

Astronauts must use reverse and parachute to slow down the ship so it will not be destroyed by impact on the surface. The machine must also locate a safe landing surface on the rough terrain of Mars, whose parts are emerging gigantic craters.

If doomsday strikes, this eight-legged ‘freak’ animal shall inherit the Earth

If doomsday strikes, this eight-legged ‘freak’ animal shall inherit the Earth

If doomsday strikes, this eight-legged ‘freak’ animal shall inherit the Earth

Whether a rock space monster crashes on our planet or radiation from an explosive star, our ocean, most humans and other life forms disappear.

But a creature is sure to survive, according to a study released Friday.

And it will continue for as long as the Sun does not die – at least another 10 billion years.

The designated heir of the Earth is the animal of delay, a microscopic animal, like an animal with eight legs that can live in water or on land, under extreme high or low pressure.

Also known as the name of water bear or pork foam, it can withstand torrential heat, a cold and high radiation, 30 years without food, and even be dried to a fresh.

Despite its small size – less than one millimeter (0.04 inches) – it is considered the most difficult of animals in the world.

The tardigrade, said researchers at Oxford and Harvard, will survive all predicted astrophysical disasters – impacts of asteroids, stars in explosion (supernovae) or bursts of gamma rays – and “be around at least 10 billion years.”

It is much better than the diagnosis of our own species.

“Without our technology that protects us humans are very sensitive species. Subtle changes in our environment affect us dramatically,” said Rafael Alves Batista of Oxford University, co-author of the study in the journal Scientific Reports.

“There are many more resistant species on Earth. Life on this planet can continue long after humans are gone.

Batista and a team set out to determine what kind of disasters would be needed to cleanse the Land of a lifetime.

And they found that it would be almost impossible – when life takes root, it is surprisingly difficult to eradicate.

Explosions of supernovae or gamma rays, electromagnetic explosions that occur in other galaxies could deplete the earth’s protective ozone layer that protects us from radiation. But life could go underground and under deep water.

And on Mars?

Even a complete loss of the atmosphere would not affect the species at the bottom of the ocean.

A large asteroid attack could cover Earth in a cloud of dust blocks the sunlight, causing a drop in temperature and the so-called “winter effect”.

Creatures perish dependent light, but in volcanic vents in the depths of the ocean, life would follow.

Without space rock large enough to cause a complete annihilation of the species is in the process of collision with our planet, which it has found.

There are no massive stars or potential sources of gamma rays close enough to boil Earth’s oceans if they burst.

The only event that kills even tardi grades is when the sun finally burned.

“Although the impacts of asteroids near supernovae or large ones are catastrophic for people, tardigrades may not be affected,” said co-author David Sloan.

The Tardigrades have a body divided into four segments, each with a pair of legs ending in sharp claws.

Surging heat may limit aircraft takeoffs globally: study

Surging heat may limit aircraft takeoffs globally: study

Rising temperatures due to global warming will make it harder for aircraft to travel in the world in the coming decades, according to a study.

During hotter periods of the day, 10 to 30 percent of the aircraft with full load may be needed to remove fuel, cargo or passengers, or wait for cooler hours to fly, according to the researchers.
“Our results suggest that weight restriction can be imposed at a non-trivial cost to airlines and affect airline operations around the world,” said Ethan Coffel of Columbia University in the US.

As the air heats up, it expands and its density decreases. In the finer air, the wings produce less lift when an airplane runs along a runway, the researchers said.

Therefore, depending on the model of the aircraft, track length and other factors, at some point, a packaging aircraft may not be able to take off safely if the temperature is too high. The weight should be discharged, delayed or canceled the flight otherwise, they said.

Global average temperatures have risen by almost one degree Celsius since 1980, and this may already have an effect.

Globally, the average temperature is expected to rise to three degrees Celsius by the year 2100, they said.

However, heat waves are becoming more common, the daily maximum daily temperatures at airports around the world to increase the ratio of four to eight degrees Celsius by 2080, according to the study.

These are the heat waves that can cause more problems.

“This highlights the risk of unmanaged climate change in aviation,” said Radley Horton, a climatologist at Columbia University.

“As the world becomes more integrated and aviation grows, there can be significant potential for economic and other cascading effects,” said Horton, co-author of the study published in the journal Climate Change.

Most studies so far have focused on how aviation can affect global warming (airplanes account for about 2 percent of global greenhouse gas emissions), not the other way around.

However, a handful of studies have warned that global warming could increase dangerous turbulence along major air routes, and winds that could extend travel time.

The new study provides the effects on a wide range of aircraft at the busiest airports in the United States, Europe, the Middle East, China and South Asia.

Researchers estimate that if greenhouse gas emissions continue unabated, fuel capacity and payload weight will be reduced by four percent on warmer days for a particular aircraft.

If the world manages to drastically reduce carbon emissions shortly, these reductions could reach 0.5 percent. 100, they said.

For an average operating aircraft today, a four percent weight reduction would be about 12 or 13 passengers less on an average 160-seat machine.

This does not account for the significant logistical and economic effects of delays and cancellations that can instantly convert one center to another, Horton said.

Some aircraft with lower temperature tolerances are much worse than others, and some airports – those with shorter runs, in warmer areas of the world or at heights, where the air is already thinner – suffer more.

Indian Astronomers Discover Supercluster of Galaxies, Name It ‘Saraswati’

Indian Astronomers Discover Supercluster of Galaxies, Name It ‘Saraswati’

 

A team of astronomers from India discovered an extremely large supergroup of galaxies – as large as 20 million billion soles – named Saraswati, the Inter-University Center for Astronomy and Astrophysics (IUCAA) based in Pune.

This is one of the largest known structures in the vicinity of the universe, 4000 million light years from Earth and about 10 billion years, IUCAA said.

Its mass extends 600 million light-years away, he said.

Scientists at this institute also participated in the discovery of last year’s gravitational waves.

The supergroup was discovered by Joydeep Bagchi, a faculty member at IUCCA; Shishir Sankhyayan, PhD student at the Indian Institute of Education and Research Sciences (IISER), Pune; Prakash Sarkar of the National Institute of Technology, Jamshedpur; Somak Raychaudhury, Director IUCAA; Joe Jacob of Newman College, Kerala and Pratik Dabhade, IUCAA researcher.

Their findings were published in the latest issue of The Astrophysical Journal, the first research journal of the American Astronomical Society.

“Large sets are the largest coherent structures of the cosmic network. They are a chain of galaxies and galaxies, bound by gravity, often extending to several hundred times the size of galaxy clusters, made up of tens of thousands of Galaxies, “IUCAA said in a statement.

Sankhyayan said that the “newly discovered Saraswati super-clusterter” spreads on a scale of 600 million light-years and may contain the mass equivalent of more than 20 billion soles.

A cluster of galaxies could have 1000-10 000. A super cluster can have groups of 40 to 43, he added.

“Our own galaxy is part of a group called super supergroup Laniakea,” IUCAA said.

Bagchi, IUCAA, lead author of the article in the journal, and co-author Sankhyayan said they were “surprised to discover this gigantic super-group of galaxies,” visible in a large spectroscopic study of distant galaxies known as the digital Sloan Sky Survey.

Sankhyayan said the data were analyzed, after which the discovery was made.

“This super-cluster is clearly integrated into a large network of cosmic filaments drawn by clusters and large gaps,” said M. Bagchi.

It has been previously said that he had reported “only a few relatively large super sets”, such as the concentration of Shapley or Great Wall Sloan in the nearby universe.

New York Times article maligning Yogi Adityanath sparks anger in Agra

New York Times article maligning Yogi Adityanath sparks anger in Agra

At a time when even the president of the United States Donald Trump is openly praising Prime Minister Narendra Modi saying he wants to follow the steps taken by Modi in bringing his country back on track, the American media is busy defaming Uttar Pradesh Yogi Adityanath and his state.

On Friday, the people of Agra became infuriated by reading a mischievous story about Yogi Adityanath published in the New York Times entitled “The Indian cleric of the puppets ascended the political ladder of India” and claimed that it was an attempt by New York Times of Yogi Adityanath’s failure and his growing stature in Indian politics.

Simulated copies of the New York Times were burned at various places in protest of the news.

Speaking to India Today, members of the Hindustani Biradari group said that Yogi Adityanath is carrying out the ‘Sabka Sath Sabka Vikas’ agenda set by Prime Minister Modi and is working towards the progress of Uttar Pradesh.

Secretary Ziauddin said that the image of Yogi Adityanath has undergone a tremendous transformation since he became Prime Minister of UP and what the New York Times wrote against PM Modi and Yogi Adityanath seems to be following an anti-Modi agenda.

He said that many Westerners of the elite, as well as the Indians, are still unable to digest that an ascetic like Yogi Adityanath could become the country’s most populous state minister and a tea vendor like Narendra Modi could become the prime minister Of the world’s largest democracy.

He said the article portrays Yogi Adityanath as the leader of a militant Hindu sect, which creates a misunderstanding among international readers that Uttar Pradesh has been taken over by militant Hindus and is not safe to come here. He said that even when US President Donald Trump praises PM Modi, the New York Times seems to be doing the opposite by questioning PM Modi’s judgment by naming Yogi Adityanath as the PM’s prime minister.

Social activist Amir Qureshi said that Yogi Adityanath is not a PM candidate, as this article appears to be portraying. While Modi is busy developing the country, Yogi Adityanath is working hard to bring Uttar Pradesh to the main states of the country. The agenda of these two is only development, not to make India a Hindu nation as the New York Times says.

Qureshi added that the New York Times reporter seems to have written the news in the United States when he should have visited Uttar Pradesh and seen for himself how these two are working hard for the country.

He said that the New York Times story is a pack of lies and that the 20 Muslim crore in India are not considered separate from their Hindu, Christian and Sikh brethren, and minor incidents between these communities should not be given as prominence as This is very great country and such disagreements are bound to happen even in small families.

Three attackers shoot at police in Jerusalem before being killed

Three attackers shoot at police in Jerusalem before being killed

Three attackers shoot at police in Jerusalem before being killed

Three assailants opened fire on Israeli police in the old city of Jerusalem on Saturday before fleeing to a healthy and very sensitive place and killed by security forces, police said.

Three people were injured in the attack, two of them seriously, police said. The incident was the most serious in recent years in Jerusalem and could increase tensions between Israelis and Palestinians. No details were given on the identity of the attackers.

The three were killed at the site known to Muslims as Haram al-Sharif and by the Jews as the Temple Mount, the site of regular clashes between the Palestinians and the Israeli police, but there are rarely any shots fired there. The site includes the Al-Aqsa Mosque and the Dome of the Rock.

A series of attacks took place in the old city of Jerusalem in recent months, but often attended knives. Police blocked the area and the Al-Aqsa complex at the holy site was closed by Friday prayers. Doors leading to the site were sealed.

The shared video on social networks showed shots in the holy place. “I was standing here and I heard the shot. I thought they were fireworks,” Basem Badawi, a 60-water vendor in the old town, told AFP.

“But then I saw the police come from anywhere.” The al-Sharif / Mount of the Haram Temple is considered the most famous site of Islam and the most sacred of Judaism.

It is critical to the Palestinian-Israeli conflict and Palestinians fear that Israel may seek a day to exercise additional control over it. It is located in East Jerusalem, occupied by Israel in the Six Day War of 1967 and later annexed in a movement not recognized by the international community.

Jews are allowed to visit, but not pray to avoid causing tensions. The site is run by the Islamic Waqf organization. Waqf officials said their guards at the site were detained by Israeli police after the attack.
A wave of unrest that erupted in October 2015 has killed at least 277 Palestinians, 42 Israelis, two Americans, two Jordanians, one from Eritrea, Sudan and one Briton, according to an AFP number. Israeli authorities say most of the dead Palestinians have attacks on knives, pistols or bombs.
