Biggest Radio Telescope in the World


In a karst depression in Pingtang, Guizhou province in southwest China located the world's largest single-dish telescope called FAST. China Sky Eye's impressive sensitivity to spot faint, polarized waves is expected to be improved.

Also known as Tianyan, or the Eye of Heaven, The Five-hundred-meter Aperture Spherical Radio Telescope (FAST) is the world’s largest single-dish telescope, situated in a karst depression in Pingtang, Guizhou province in southwest China. Nearby settlements were relocated to reduce electromagnetic emissions which could interfere with the telescope’s sensitive operations. It appears to be a giant golf ball in the middle of China’s new Pingtang Astronomy Town.

FAST HAS BEEN in the making for a long time. In the early 2000s, China angled to host the Square Kilometre Array, a collection of coordinated radio antennas whose dishes would be scattered over thousands of miles. But in 2006, the international SKA committee dismissed China, and then chose to set up its distributed mondo-telescope in South Africa and Australia instead, as shows skyandtelescope.

Health Benefits of Papaya


​Papaya: Plenty to Be 'Yaya' (Proud) About
Papaya offer a variety of health benefits including lowering risk of heart disease and cancer, and promoting digestive health

Next to apples, oranges and watermelon, the papaya is another commonly eaten fruit in Singapore. Dietitian Phoebe Thong from Outram Community Hospital (OCH) shares more about the healthy goodness of this tropical fruit

Papayas can be found in our supermarkets all year round and are an inexpensive sweet treat. In addition to being delicious, this popular fruit also offers many health benefits:
  • May lower risk of heart disease and cancer - Free radicals are reactive molecules created during the body’s metabolism that promote oxidative stress, which may potentially lead to diseases such as heart diseases and cancer. Categorised as a yellow or orange fruit, papaya is high in antioxidants such as Vitamin A and E which can help to neutralise these free radicals.
  • Promotes digestive health - A great source of fibre, papaya can help to prevent constipation and promote good bowel movements for better digestive health. Consuming such high-fibre fruits can also help to keep you fuller for longer, which in turn will prevent you from overeating during or in between meals.
  • Regulates heart beat and blood pressure - Papaya contains potassium, which is a mineral that can also be found in many vegetables and fruits. Potassium is important for your heart, nerve and muscles to function properly and an inadequate intake may result in muscle weakness and cramping.
  • Contains Papain - Papain, an enzyme found in papaya, can help to break down tough protein chains into smaller protein fragments such as amino acids and peptides, which aids digestion. In fact, papain can also be used to tenderise meat.


From better digestion to building immunity, 5 reasons why you should eat papaya regularly
From papaya chaat to papaya juice , it's time you incorporate this superfruit in your diet to get all it's healthy benefits

Fruits are great sources of nutrients and eating a bowl full of them daily can keep you energised and immune to a number of diseases.

Not many of us like papaya, but you would be surprised to know that the fleshy tropical fruit is a storehouse of vitamins C and A. It also consists of fiber and healthy plant compounds that boost immunity. Christopher Columbus had said that the papaya is the fruit of angels and it seems that the discoverer of the Americas was right.

Here are a few health benefits of regular consumption of papaya:
  • Boosts immunity - Rich in Vitamin C, papaya is one of the best edibles out there to strengthen the immune system to fight against diseases and infection. Papaya contains more than 200 %of your daily dose of Vitamin C. Apart from this, the fruit is also rich in vitamins A, B, and K which also boost immunity.
  • Anticancer properties - The lycopene in papaya can help reduce cancer risk. Scientists have also found that papaya showed anticancer activity in breast cancer cells.
  • Antioxidant - Papayas contain carotenoids that can neutralise free radicals and reduce oxidative stress in older adults. Oxidative stress can lead to chronic inflammation which in turn harms the immune system.
  • Fight inflammation - A number of studies have shown that papaya helps reduce inflammatory markers in the human body which are considered to be the main cause of many diseases. It is also a storehouse of carotenoids that can reduce inflammation.
  • Aids digestion - The enzyme named papain which is found in papaya can help make protein easier to digest.


Health Benefits of Papaya

Carica papaya is the scientific name of the orange and green fruit known more commonly as papaya. It tastes sweet and has a soft texture that many find appealing. The seeds are also edible, although they’re more bitter than the fruit itself.

Papayas are originally from Central America. They grow best in a tropical region where there is plentiful rainfall but little long-term flooding. Freezing temperatures may damage a papaya crop. Indigenous people in the area ate papayas and used them for medicinal purposes. In the 1500s and 1600s, Spanish and Portuguese colonizers brought the seeds to other tropical areas of the globe, including the Philippines and India. Today, Hawaii, the Philippines, India, Ceylon, Australia, and tropical regions in Africa are the most fruitful papaya-producing regions. Smaller papaya-farming operations still exist in Central and South America.

Papaya has many different names all over the globe. In Australia, it’s called a pawpaw. In southern Asia, it’s sometimes called a kepaya, lapaya, or tapaya. Its name in French is sometimes “figueir des iles,” or fig of the islands. Some Spanish names for papaya include “melon zapote,” “fruta bomba,” or “mamona.” Health Benefits:
  • Protection Against Heart Disease - Papayas contain high levels of antioxidants vitamin A, vitamin C, and vitamin E. Diets high in antioxidants may reduce the risk of heart disease. The antioxidants prevent the oxidation of cholesterol. When cholesterol oxidizes, it’s more likely to create blockages that lead to heart disease.
  • Digestion and Reduced Inflammation - The papaya fruit contains two enzymes, papain and chymopapain. Both enzymes digest proteins, meaning they can help with digestion and reduce inflammation. Papain is an ingredient in some over-the-counter digestive supplements to help with minor upset stomach. Both papain and chymopapain also help to reduce inflammation. They may help acute pain, like those from burns or bruises, and they can help with chronic inflammatory conditions like arthritis and asthma.
  • Immune System - Eating foods high in vitamin C can help to boost the immune system, allowing the body to fight off bacterial and viral illnesses. Papaya has a good amount of this antioxidant, making it part of an immune-healthy diet. Papaya is also a good source of Vitamin A, another important vitamin for a healthy and functional immune system.
  • Potentially Protects Against Prostate Cancer - Lycopene is a natural pigment found in foods that are red or orange. Tomatoes, watermelon, and papaya are good sources of lycopene. Some experts believe that eating more lycopene reduces the risk of prostate cancer, but some studies have been inconclusive. However, in other studies, eating a diet high in lycopene along with green tea reduced the risk of prostate cancer significantly.
  • Nutrition - A medium-sized papaya contains more than 200% of the vitamin C you need per day, helping to reduce the risk of heart disease and boost the immune system.


What are the health benefits of papaya?

Papayas grow in tropical climates and are also known as papaws or pawpaws. Their sweet taste, vibrant color, and the wide variety of health benefits they provide make them a popular fruit. The papaya, a previously exotic and rare fruit, is now available at most times of the year.

The possible health benefits of consuming papaya include a reduced risk of heart disease, diabetes, cancer, aiding in digestion, improving blood glucose control in people with diabetes, lowering blood pressure, and improving wound healing. Papayas are a soft, fleshy fruit that can be used in a wide variety of culinary ways. Here we will explore more on the health benefits, uses, how to incorporate more of them into your diet, and what nutritional value papayas have.

The nutrients found in papaya are thought to have a range of health benefits. They may help protect against a number of health conditions:
  • Age-related macular degeneration - Papaya has a range of health benefits including asthma prevention and even anti-cancer properties. Zeaxanthin, an antioxidant found in papaya, filters out harmful blue light rays. It is thought to play a protective role in eye health, and it may ward off macular degeneration. However, a higher intake of all fruits has been shown to decrease the risk of and progression of age-related macular degeneration.
  • Asthma prevention - The risk of developing asthma is lower in people who consume a high amount of certain nutrients. One of these nutrients is beta-carotene, contained in foods like papaya, apricots, broccoli, cantaloupe, pumpkin, and carrots.
  • Cancer - Consuming the antioxidant beta-carotene, found in papayas, may reduce cancer risk. Among younger men, diets rich in beta-carotene may play a protective role against prostate cancer, according to a study published in the journal Cancer Epidemiology and Prevention Biomarkers.
  • Bone health - Low intakes of vitamin K have been associated with a higher risk of bone fracture. Adequate vitamin K consumption is important for good health, as it improves calcium absorption and may reduce urinary excretion of calcium, meaning there is more calcium in the body to strengthen and rebuild bones.
  • Diabetes - Studies have shown that people with type 1 diabetes who consume high-fiber diets have lower blood glucose levels, and people with type 2 diabetes may have improved blood sugar, lipid, and insulin levels. One small papaya provides about 3 grams of fiber, which is equivalent to just 17 grams of carbohydrates.
  • Digestion - Papayas contain an enzyme called papain that aids digestion; in fact, it can be used as a meat tenderizer. Papaya is also high in fiber and water content, both of which help to prevent constipation and promote regularity and a healthy digestive tract.
  • Heart disease - The fiber, potassium, and vitamin content in papaya all help to ward off heart disease. An increase in potassium intake along with a decrease in sodium intake is the most important dietary change that a person can make to reduce their risk of cardiovascular disease.
  • Inflammation - Choline is a very important and versatile nutrient found in papayas that aids our bodies in sleep, muscle movement, learning, and memory. Choline also helps to maintain the structure of cellular membranes, aids in the transmission of nerve impulses, assists in the absorption of fat, and reduces chronic inflammation.
  • Skin and healing - When used topically, mashed papaya appears to be beneficial for promoting wound healing and preventing infection of burned areas. Researchers believe that the proteolytic enzymes chymopapain and papain in papaya are responsible for their beneficial effects. Ointments containing the papain enzyme have also been used to treat decubitus ulcers (bedsores).
  • Hair health - Papaya is also great for hair because it contains vitamin A, a nutrient required for sebum production, which keeps hair moisturized. Vitamin A is also necessary for the growth of all bodily tissues, including skin and hair. Adequate intake of vitamin C, which papaya can provide, is needed for the building and maintenance of collagen, which provides structure to skin
  • Nutrition - Papayas are an excellent source of vitamin C, and one single medium fruit provides 224 percent of recommended daily intake. They also have B vitamins, alpha and beta-carotene, lutein and zeaxanthin, vitamin E, calcium, potassium, vitamin K, and lycopene, the powerful antioxidant most commonly associated with tomatoes.


8 Evidence-Based Health Benefits of Papaya

The papaya is an incredibly healthy tropical fruit. It’s loaded with antioxidants that can reduce inflammation, fight disease and help keep you looking young. Here are 8 health benefits of papaya:
  • Delicious and Loaded With Nutrients - Papaya is the fruit of the Carica papaya plant. It originated in Central America and Southern Mexico but is now grown in many other parts of the world. Papaya contains an enzyme called papain, which can break down the tough protein chains found in muscle meat. Because of this, people have used papaya to tenderize meat for thousands of years.
  • Has Powerful Antioxidant Effects - Free radicals are reactive molecules created during your body’s metabolism. They can promote oxidative stress, which can lead to disease. Antioxidants, including the carotenoids found in papayas, can neutralize free radicals. Studies note that fermented papaya can reduce oxidative stress in older adults and people with prediabetes, mild hypothyroidism and liver disease.
  • Has Anticancer Properties - Research suggests that the lycopene in papaya can reduce cancer risk. It may also be beneficial for people who are being treated for cancer. Papaya may work by reducing free radicals that contribute to cancer. Additionally, papaya may have some unique effects not shared by other fruits.
  • May Improve Heart Health - Adding more papaya to your diet may boost your heart health. Studies show that fruits high in lycopene and vitamin C may help prevent heart disease. The antioxidants in papaya may protect your heart and enhance the protective effects of “good” HDL cholesterol.
  • May Fight Inflammation - Chronic inflammation is at the root of many diseases, and unhealthy foods and lifestyle choices can drive the inflammatory process. Studies show that antioxidant-rich fruits and vegetables like papaya help reduce inflammatory markers.
  • May Improve Digestion - The papain enzyme in papaya can make protein easier to digest. People in the tropics consider papaya to be a remedy for constipation and other symptoms of irritable bowel syndrome (IBS). In one study, people who took a papaya-based formula for 40 days had significant improvement in constipation and bloating.
  • Protects Against Skin Damage - In addition to keeping your body healthy, papaya can also help your skin look more toned and youthful. Excessive free radical activity is believed to be responsible for much of the wrinkling, sagging and other skin damage that occurs with age. The vitamin C and lycopene in papaya protect your skin and may help reduce these signs of aging.
  • Delicious and Versatile - Papaya has a unique taste that many people love. However, ripeness is key. An unripe or overly ripe papaya can taste very different from a perfectly ripe one. When optimally ripe, papaya should be yellow to orange-red in color, although a few green spots are fine. Like an avocado, its skin should yield to gentle pressure. Its flavor is best when cold, so it’s a good idea to keep it refrigerated whenever possible.

Two mass shootings in 10 days in the U.S.

Update 4 Jul 2022: Mass shooting on US Independence Day

The event in the city of Highland Park, Illinois, was suddenly halted shortly after 10:00 local time (15:00 GMT), when several shots were heard. Twenty-four people were taken to hospital, officials say. A suspect has been named as Robert E Crimo III, 22. Police said he is considered armed and dangerous. Police said the suspect appeared to have targeted the parade's attendees at random with a high-powered rifle. The suspected gunman opened fire at the parade at around 10:15 local time, just a few minutes after it began.

The event was scheduled to include floats, marching bands, and community entertainment as part of the city's Independence Day celebrations. But what should have been one of the happiest days of the year quickly turned to panic, with pushchairs, purses and lawn chairs left discarded on the street as crowds fled from the scene. The suspect is believed to have fired at members of the public from the rooftop of a nearby shop, where police say they recovered "evidence of a firearm."

Five adults were killed at the scene, as well as a further victim who the local coroner said died in a nearby hospital. "On a day that we came together to celebrate community and freedom, we're instead mourning the tragic loss of life," said city mayor Nancy Rotering. The Fourth of July is a national holiday marking the date the American colonies declared independence from Great Britain in 1776.


Gunman kills four in Oklahoma medical centre

A man armed with a rifle and handgun killed four people inside a medical building in Tulsa, Oklahoma on Wednesday (June 1) before fatally shooting himself, police said, in the latest of a series of mass shootings to rattle the United States.

Police arrived at the St. Francis Hospital three minutes after receiving a call about the shooting on Wednesday afternoon and followed the sound of gunfire up to the Natalie Building’s second floor, Tulsa deputy police chief Jonathan Brooks told reporters. The officers made contact with the victims and the suspect five minutes later, Mr Brooks said.

Police responses have come under increased scrutiny after a gunman killed 19 children and two teachers in a Texas school classroom last week while officers waited outside for nearly an hour. Wednesday’s incident in Tulsa is the latest in a series of mass shootings that have shocked Americans and reignited debates about gun control. Two weeks before the Uvalde shooting, a white gunman killed 10 people at a supermarket in a Black neighbourhood in Buffalo, New York.



Tulsa shooting is the nation's 233rd mass shooting in 2022, per Gun Violence Archive

There have so far been at least 233 mass shootings in 2022, according to the nonprofit organization Gun Violence Archive — including today's shooting in Tulsa.

June 1 was the 152nd day of the year. This means there have been more mass shootings this year than there have been days in 2022.

CNN and the GVA define a mass shooting as a shooting that injured or killed four or more people, not including the shooter.

A teenage gunman murdered at least 19 children and two teachers after storming into a Texas elementary school on Tuesday (May 24), the latest bout of gun-fueled mass murder in the United States and the nation's worst school shooting in nearly a decade.

The carnage began with the 18-year-old suspect, identified as Salvador Ramos, shooting his own grandmother, who survived, authorities said. He fled that scene and crashed his car near the Robb Elementary School in Uvalde, Texas, a town about 130km west of San Antonio. There he launched a bloody rampage that ended when he was killed, apparently shot by police.

The motive was not immediately clear. Law enforcement officers saw the gunman, clad in body armour, emerge from his crashed vehicle carrying a rifle and "engaged" the suspect, who nevertheless managed to charge into the school and open fire, Texas Department of Public Safety (DPS) Sergeant Erick Estrada said on CNN.

mass shooting 10 days earlier claimed 10 lives in Buffalo, New York, in a predominantly Black neighborhood. Authorities have charged an 18-year-old who they said had traveled hundreds of miles to Buffalo and opened fire with an assault-style rifle at a grocery store.

A gunman killed at least 18 children and a teacher on Tuesday in a rural Texas elementary school, officials said, in the deadliest American elementary school shooting since the massacre at Sandy Hook Elementary a decade ago.

The slayings took place just before noon at Robb Elementary School, where second through fourth graders in Uvalde, a small city west of San Antonio, were preparing to start summer break this week. “He shot and killed horrifically, incomprehensibly,” Governor Greg Abbott said in a news conference.

As terrified parents in Uvalde late Tuesday waited for word of their children’s safety and law enforcement officials raced to piece together how the massacre had transpired, the mass shooting was reopening national political debate over gun laws and the prevalence of weapons. Ten days earlier, a gunman fatally shot 10 people inside a Buffalo, New York, grocery store.

A heavily armed 18-year-old man shot 10 people dead on Saturday (May 14) at a Buffalo, New York grocery store in a "racially motivated" attack that he live-streamed on camera, authorities said.

The gunman, who was wearing body armor and a helmet, was arrested after the massacre, Buffalo's police commissioner Joseph Gramaglia told a news conference. Gramaglia put the toll at 10 dead and three wounded. Eleven of the victims were African Americans. The gunman shot four people in the parking lot of the Tops supermarket, three of them fatally, then went inside and continued firing, Gramaglia said.

Among those killed inside the store was a retired police officer working as an armed security guard. The guard "engaged the suspect, fired multiple shots," but the gunman shot him, Gramaglia said. When police arrived, the shooter put the gun to his neck, but was talked down and surrendered, he added.

An 18-year-old white gunman shot 10 people to death and wounded three others at a grocery store in a Black neighborhood of Buffalo, New York, before surrendering after what authorities called an act of “racially motivated violent extremism.”

Authorities said the suspect, who was armed with an assault-style rifle and appeared to have acted alone, drove to Buffalo from his home in a New York county “hours away” to launch a Saturday afternoon attack that he broadcast on the internet.

Eleven of the 13 people struck by gunfire were Black, officials said. The two others were white. The racial breakdown of the dead was not made clear. The suspect, who was not immediately named by police, was heavily armed and dressed in tactical gear, including body armor, police said.


Gun violence in the United States

Gun violence in the United States results in tens of thousands of deaths and injuries annually. Guns were the leading cause of death for children in 2020. In 2018, the most recent year for which data are available as of 2021, the Centers for Disease Control and Prevention's (CDC) National Center for Health Statistics reports 38,390 deaths by firearm, of which 24,432 were by suicide. The rate of firearm deaths per 100,000 people rose from 10.3 per 100,000 in 1999 to 12 per 100,000 in 2017, with 109 people dying per day or about 14,542 homicides in total, being 11.9 per 100,000 in 2018. In 2010, there were 19,392 firearm-related suicides, and 11,078 firearm-related homicides in the U.S. In 2010, 358 murders were reported involving a rifle while 6,009 were reported involving a handgun; another 1,939 were reported with an unspecified type of firearm. In 2011, a total of 478,400 fatal and nonfatal violent crimes were committed with a firearm.

About 1.4 million people have died from firearms in the U.S. between 1968 and 2011. This number includes all deaths resulting from a firearm, including suicides, homicides, and accidents. Compared to 22 other high-income nations, the U.S. gun-related homicide rate is 25 times higher. Although it has half the population of the other 22 nations combined, among those 22 nations studied, the U.S. had 82 percent of gun deaths, 90 percent of all women killed with guns, 91 percent of children under 14 and 92 percent of young people between ages 15 and 24 killed with guns, with guns being the leading cause of death for children. The ownership and regulation of guns are among the most widely debated issues in the country.

African American populations in the United States experience high amounts of firearms injury and homicide. Although mass shootings are covered extensively in the media, mass shootings in the United States account for only a small fraction of gun-related deaths. Regardless, mass shootings occur on a larger scale and much more frequently than in other developed countries. School shootings are described as a "uniquely American crisis", according to The Washington Post in 2018. Children at U.S. schools have active shooter drills. According to USA Today, in 2019 "about 95% of public schools now have students and teachers practice huddling in silence, hiding from an imaginary gunman."
