Scientists develop a 'mini sun' to study solar wind

To get a better understanding of solar winds, scientists at the University of Wisconsin-Madison built a 'mini sun' that mimics the real sun. Dubbed the 'Big Red Ball', researchers pump in helium gas, just like its present in the actual sun, and turn it into plasma. Moreover, a magnet present at the centre also creates a magnetic field when electric current is applied to the machine. The research published in the journal Nature Physics said that the object will help scientists study how solar wind is generated and how it transforms as it travels to the earth.

UN Secretary-General&nbsp;Ant&oacute;nio Guterres&nbsp;has said the planet is on a red alert as governments across the globe are failing to meet their climate change goals, and 2021 is a 'make or break year'.
The statement came during the release of a new report analysing&nbsp;the climate action plans submitted by 75 nations.&nbsp;It found that the current policies won't come close to meeting the goals of the Paris Agreement.&nbsp;
At this rate, we should expect more heat waves, wildfires, rise in sea level and food shortages for millions.&nbsp;The UN urged nations to step up their efforts in the fight against climate change.

A huge iceberg (1270 km&sup2;) twice the size of Mumbai&nbsp;has broken off the 150-m thick Brunt Ice Shelf, almost a decade after scientists at British Antarctic Survey (BAS) first detected cracks in the ice.
Separation of 1,270 sq km chunk of frozen water is the&nbsp;third major chasm to actively tear across the Brunt Ice Shelf in the last decade.&nbsp;
'Over the coming weeks or months, the iceberg may move away; or it could run aground and remain close to Brunt Ice Shelf,' said the BAS&nbsp;Director.&nbsp;

Global rising temperatures and the melting of Arctic ice has forced polar bears to adopt a land-based diet. They have switched from&nbsp;hunting seals to catching fish, geese and even lemmings, Russian scientists said on the eve of International Polar Bear Day.&nbsp;
Additionally, the iconic bear species is now using four times more energy to survive because of major ice loss in the Arctic, found a separate study.&nbsp;
As global warming rises, the already endangered species with a global population of up to 30,000, faces an uncertain future.&nbsp;

The livelihoods and food security of hundreds of millions of people in India stand threatened from&nbsp;overexploitation of vital water supplies, finds a new study published in the journal Science Advances.&nbsp;
The authors say groundwater,&nbsp;a critical resource for food security,&nbsp;makes up&nbsp;40% of the country's water supply&nbsp;has been steadily depleting for years. Over-extraction by way of tube wells has left "critically low groundwater availability" in the country's northwest and south, according to the research.
If the trend continues, winter harvests could decrease by 20% nationwide and by 68% in the most severely affected areas, noted the authors.&nbsp;

Childhood exposure to air pollution, including&nbsp;wildfire smoke and car exhaust, for even short periods of time, can lead to higher rates of heart disease and other ailments in adulthood, says a new Stanford-led&nbsp;study.&nbsp;
Published in&nbsp;Nature Scientific Reports, the study&nbsp;confirms previous research that bad air can alter gene regulation in a way that may impact long-term health.
Exposure to fine particulate known as PM2.5, carbon monoxide and ozone over time was linked to a&nbsp;change in gene expression which may be passed down to future generations.

&nbsp;Israel closed all its Mediterranean beaches until further notice on Sunday, days after an offshore oil spill deposited an estimated dozens of tons of tar across more than 100 miles of coastline in what officials are calling one of the country's worst ecological disasters.
Activists began reporting globs of black tar on Israel's coast last week after a heavy storm washed the petroleum byproducts ashore, wreaking havoc on wildlife.
Researchers with the country's Agriculture Ministry determined Sunday that a dead young fin whale that washed up on a beach in southern Israel died from ingesting the viscous black liquid, according to Kan, Israel's public broadcaster.
Israel's Nature and Parks Authority has called the spill &ldquo;one of the most serious ecological disasters&rdquo; in the country's history.

There are very few rivers across the globe that remain undamaged by humanity, according to a new study published in journal Science.
The study states that biodiversity of more than half of rivers had been profoundly affected and a lot of the big fish species have been replaced.
Rising temperatures due to the climate crisis, pollution, overfishing and farm irrigation are some factors causing damage to the rivers.
The study adds that rivers in western Europe and North America are worst hit. Many rivers are now unrecognisable from how they looked before the industrial revolution.&nbsp;

Dolphins have developed several personality traits that are similar to humans, including curiosity and sociability, according to a new study by researchers from the&nbsp;University of Hull.
The study states that despite evolving in very different environments, there is a convergence of personality traits between humans and dolphins.
It further states that dolphins have brains that are larger than what their body requires for bodily functions. This makes them highly intelligent and curious creatures.
The research however concluded by saying that it must not be assumed that these personality traits between humans and dolphins are identical.

UN secretary-general, Ant&oacute;nio Guterres&nbsp;has warned that humanity is waging a 'suicidal and senseless' war on nature, accelerating destruction of life on Earth.
The secretary-general's warning came at the launch of a UN report that enlisted the triple emergency. This includes the pollution and climate crisis and the devastation of wildlife.
The key to a sustainable future is making peace with nature, he shared.
Certain measures like taxing carbon emissions and diverting destructive farming to green energy, must be inculcated.

Residents, some of whom lack heat or basic amenities in their own homes due to the unusually chilly weather, have been rescuing cold-stunned sea turtles and taking them to a convention centre in South Texas.
The Convention Center started pitching in Monday when it's neighbour, Sea Turtle Inc., could no longer handle the number of sea turtles being dropped off, and their mostly outdoor operation had lost power.&nbsp;
The centre&nbsp;says they've "collected" more than 3,500 sea turtles so far, hesitating&nbsp;to use the word rescued because they know they will end up "losing&nbsp;some."

Increased exposure to air pollution increases the risk of infertility, according to a new study by Peking University Third hospital in China.
The study found that those living with small particles of pollution had a 20% greater risk of infertility, which the researchers defined as 'not becoming pregnant within a year of trying'.
According to a Guardian report,&nbsp; while the scientists did not state how pollution poses a risk to fertility, it is believed that pollution particles cause inflammation in the body which could damage sperm and egg production.
It further added that weight, age and smoking also risk factors.&nbsp;

Released by Maxar Technologies, the high-resolution satellite images of the landslide at Uttarakhand&nbsp;show that flash floods in Rishi Ganga and Dhauli Ganga river catchment areas. The landslides caused by a major snow avalanche near Raini village of Chamoli district and left behind the devasting trail of destruction. The death toll in the tragedy has now reached 58.&nbsp;As many as 146 people are still missing in the wake of the tragedy.
The devastating flash flood in Uttarakhand&rsquo;s Chamoli district was caused by landslides and a snow avalanche that brought down debris, mud and soil into the downstream areas of a stream.

In a surprising find, scientists have discovered immobile life forms under a 900 metre thick&nbsp;Antarctic ice shelf and say it is life that shouldn't be there.
The discovery comes after a team led by the British Antarctic Survey drilled through the Filchner-Ronne ice shelf and dropped a camera down the hole to search for mud on the sea bed.
To their surprise, they found a boulder with nearly 16 sponges, 22 unidentified animals including some that appear to be barnacles.
The creatures found, scientists said, likely survive on photosynthetic organisms that need sunlight which is missing beneath the ice shelf and that's the reason they shouldn't be here.
The findings suggest that life in Antarctica's harshest environment is more diverse and adaptable than previously thought. The scientists now hope to study the creatures in more detail.
