According to the Union of Concerned Scientists, there are nearly 2,800 working satellites in space. We depend on these devices for technology we use every day, such as video calls, online maps, satellite TV, and weather tracking. Scientists use them to study space and learn more about our planet.

But there are many other satellites in orbit that are no longer working. They’re among the objects cluttering up space. Some of these eventually fall back toward Earth, either landing or burning up in the atmosphere. But much of this space junk circles Earth for decades.

Orbital debris, a type of space junk, is any human-made object that has stopped working but continues to float around the Earth. This includes abandoned satellites and pieces of spacecraft, such as rocket stages.

Space junk also includes fragments of objects. These occur when satellites collide with things. They also result from an object crashing into an old rocket stage that still contains fuel, causing an explosion.

Heather Cowardin works at NASA. She says the United States is tracking more than 23,000 pieces of space debris. These tiny fragments can damage working satellites, which can affect research in space. That’s why cleanup efforts are so important.

A woman suffering from a rare blood condition is on a quest to find her estranged biological father, who may enable her to get a potentially life-saving transplant if he donates his bone marrow.

Sarah Langdale, 32, was diagnosed with severe anemia when she was two.

This disease occurs when the body stops producing new enough blood cells. Patients with the condition are often fatigued and more prone to infections, as well as uncontrolled bleeding.

“I’m having blood transfusions every three weeks. I eventually started to lose my color and energy and I can´t do anything” Langdale told local news outlet Northampton Chronicle and Echo. Doctors have told her that she urgently needs a bone marrow transplant before her condition worsens.

“I really need my Dad to come forward, I’ve been looking hard for him. I`ll die without a transplant and I hope I can find a better match with him or my half-siblings. And I´m relying on someone seeing my story and coming forward with information. I can only live in hope.

China used to be the largest recipient of excess plastic waste, but the country cracked down on the practice in 2018. Since then, countries like the UK, the US, and Canada have scrambled to find other dumping grounds.

Many of these countries have since restricted the practice as well after getting inundated with junk plastic. Both the Philippines and Malaysia have sent shipping containers full of plastic waste back to where they came from.

"Malaysia will not be the dumping ground of the world", Yeo Bee Yin, Malaysia’s environment minister, said at the time. "We will fight back. Even though we are a small country, we can’t be bullied by developed countries."

"What the citizens of the UK [and other countries] think they have sent for recycling are actually being dumped in our country," she added. "Malaysians have a right to clean air, clean water, and a clean environment to live in, just like citizens of developed nations."

Low-income countries such as Bangladesh, Laos, Senegal, and Ethiopia have emerged as the new dumping grounds due to lax environmental laws, according to the Guardian.

Environmental groups have long warned that the plastic pollution crisis has been spiraling out of control. Many countries have vowed to reduce plastic production, and global conventions have been convened to improve international recycling and waste management. But plastic production is expected to increase by 40% over the next decade.

While the EU will seek to take responsibility for the amount of waste it generates, countries such as the UK will continue to pass the responsibility elsewhere.

"We had assumed the UK would at least follow the EU, and so it is a shock to find out now that instead they choose to have a far weaker control procedure, which can still permit exports of contaminated and difficultto-recycle plastics to developing countries," Jim Puckett, director of the Basel Action Network, told the Guardian. He added: "They are talking the talk, but they have failed to walk the walk."

New player in cancer’s spread

When people hear that they might have cancer, perhaps the only thing more frightening than the C word is the M word. Metastatic disease — in which the tumor has traveled beyond its primary place to other spots in the body — is responsible for nine out of every 10 cancer deaths.

Recently an unexpected player in this process has emerged: a common bacterium. Fusobacterium nucleatum, which normally lives harmlessly in the gums, appears to have a role in the spread of some cancers of the colon, esophagus, pancreas and — possibly — breast. Laboratory studies and evidence in patients indicate that the microbe can travel through the blood and infect tumor cells by attaching to a sugar molecule on their surface. There it provokes a range of signals and immune responses known to cause tumor cells to migrate. If further confirmed, the work with F. nucleatum could add to a growing understanding of how the microbiome influences cancer progression and may even point the way to fresh approaches to treatment.

Insomnia

Insomnia is the most common of all sleep complaints. Almost everyone has occasional sleepless nights, perhaps due to stress, heartburn or drinking too much caffeine or alcohol. Insomnia is a lack of sleep that occurs on a regular or frequent basis, often for no apparent reason.

How much sleep is enough varies. Although 7 1/2 hours of sleep is about average, some people do fine on 4 or 5 hours of sleep. Other people need 9 or 10 hours a night.

Inability to get a good night’s sleep can affect not only your energy level and mood but your health as well because sleep helps bolster your immune system. Fatigue, at any age, leads to diminished mental alertness and concentration. Lack of sleep is linked to accidents both on the road and on the job.

About one out of three people have insomnia sometime in their life. Sleeplessness may be temporary or chronic. You don’t necessarily have to live with sleepless nights. Some simple changes in your daily routine and habits may result in better sleep.

ABSTRACT. This study aimed to investigate the point of intersection of teachers’ and learners’ perceptions regarding language learning strategies. Using an original questionnaire developed in a classroom situation, the study examined reported frequency of strategy use by international students and teacher perceptions regarding the importance of strategy use. There was a high level of accord (71 per cent) between strategies which students reported using highly frequently and those which teachers reported regarding as highly important, an encouraging finding somewhat at variance with the results of some previous studies. Implications of these results for the teaching/learning situation are discussed.

Life on a desert island

Alexander,L.G.

Most of us have formed an unrealistic picture of life on a desert island. We sometimes imagine a desert island to be a sort of paradise where the sun always shines. Life there is simple and good. Ripe fruit falls from the trees and you never have to work. There is also the other side of the picture: Life on a desert island is wretched - you either starve to death or live like Robison Crusoe waiting for a boat which never comes. Perhaps there is an element of truth in both these pictures, but few of us have had the opportunity to find out.

Two men who recently spent five days on a coral island whished they had stayed there no longer. They were taking a badly damaged boat from the Virgin Islands to Miami to have it repaired. During the journey, their boat began to sink. They quickly loaded a small rubber dinghy with food, matches, and cans of beer and rowed for a few miles across the Caribbean until they arrived at a tiny coral island. There were hardly any trees on the island and there was no water to drink, but this didn’t prove to be a problem since the men collected rain-water in the rubber dinghy. As they had brought a spear gun with them, they had plenty to eat. They caught lobster and fish every day, and, as one of them put it, “ate like kings”. When a passing tanker rescued them five days later, both men were genuinely sorry that they had to leave.

“Life there is simple and good. Ripe fruit falls from the trees and you never have to work.”

Many feel as if the covid-19 pandemic is stealing their present and jeopardising their future. But this unprecedented global public health emergency is also precipitating the destruction of our past, one piece at a time. Indeed, the pandemic has exacerbated the theft and trafficking of antiquities and historical manuscripts, eroding our collective memory and ability to share it with future generations. Although the theft of antiquities has been a problem since antiquity itself, its pace has increased during the pandemic, particularly in the Middle East and North Africa — areas rich in heritage sites.
