Study solves mystery origin of Stonehenge’s iconic boulders

Stonehenge, a Neolithic wonder in southern England, has vexed historians and archaeologists for centuries with its many mysteries: How was it built? What purpose did it serve? Where did its towering sandstone boulders come from?

That last question may finally have an answer after a study published Wednesday found that most of the giant stones — known as sarsens — seem to share a common origin 25 kilometres (16 miles) away in West Woods, an area that teemed with prehistoric activity.

The finding boosts the theory that the megaliths were brought to Stonehenge about the same time: around 2,500 BCE, the monument’s second phase of construction, ……….

Scientists revive 100 million-year-old microbes from deep under seafloor

Scientists have succeeded in reviving microbes retrieved from sediment deep under the seafloor in the heart of the South Pacific that had survived in a dormant state for 101.5 million years in research illustrating the resiliency of life on Earth.

The microbes, spanning 10 major and numerous minor groups of bacteria, maybe the planet’s oldest-known organisms. The scientists said on Tuesday the microbes were present in clay samples drilled from the research vessel JOIDES Resolution about 245 feet (74.5 meters) under the seafloor, below 3.5 miles (5.7 km) of water.

Up to 99 per cent of the microbes, dating back to the age of dinosaurs, that were found encased in the sediment survived despite having essentially……..

Flood engulfs over a third of Bangladesh

Around 37 percent of the country’s total area has been flooded, said Prof AKM Saiful Islam, of Buet’s Institute of Water and Flood Management, after analysing satellite images.

People of low-lying areas are the worst affected victims of this natural disaster. Some of them have been waterlogged for over a month, he told The Daily Star yesterday.

In 1998, around 68 percent of the country was inundated, 61 percent in 1988, 42 percent in 2007 and 2017, and 38 percent in 2004, Prof Saiful mentioned.

1,000 pilgrims arrive in Mina to perform hajj

About 1,000 pilgrims arrived on the Mina Valley outside Makkah on Wednesday to participate in this year’s hajj amid the coronavirus pandemic.

This time, the Saudi government has imposed restrictions to curb the spread of the virus which brought the global economy to its knees and force closure of businesses and places of worships across the world.

Hajj rituals begin with the Day of Tarwiyah (fetching water) and there are no major rituals, so the pilgrims will spend their time praying and reflecting until sunrise on Thursday, reports Arab News.

Dengue, Corona and some of their memorization talk

There are many similarities between the initial symptoms of dengue and corona. These are such as fever, headache, body aches. Now the dengue season is starting. India and Singapore are suffering from dengue and corona together. Although these two viruses enter and reproduce differently, they both affect our immune system. Once someone has dengue, it will not happen again, the idea is not right. Rather, the second time dengue is caused by antibodies already in the body, through antibody dependent enhancement (ADE), the virus is more likely to infect the body. Scientists have also speculated that this ADE may have a detrimental role in the case of corona.
.
So now if you have a fever, you have to keep dengue in mind. To be tested. Last year, there were more than 1 lakh dengue cases in Bangladesh. Corona, floods, and if dengue comes along, will we be able to cope? Dengue? Or, haven’t you? People will be upset about that. With Covid-19, there is already a lot of pressure on our health system. There was a lack of coordination among the various committees including the Ministry, the Department, the Technical Committee.
.
Since January, when we have said and written about Covid-19, or when many countries started thinking about PPE, ventilators, our officials did not pay attention. Later when they took cognizance of the matter, they argued that the PPE crisis, the test kit crisis is all over the world. It is getting late to get the supply of these.
.
Now is the time to think very well about dengue. Hopefully, there are enough dengue detection kits like NS1 kit in Bangladesh, with which dengue can be detected on the first day of fever. If we can do that, we will not have any confusion about dengue. Hopefully, there is enough manpower and equipment.

If not here’s a new product just for you! If you don’t do this, two months from today, you will have to deal with dengue and memorize the same words that you may be tired of saying. Those are the memorized words …. You know, many countries including India, Singapore, Brazil are suffering from dengue problem, there is a dearth of medical supplies and dengue eradication chemicals in the market at the moment, and we have some manpower problems, we are issuing circulars for recruitment. , Having a little temporary problem. We will win against dengue. “

Covid-19 patients may loss immunity in months: UK study

Covid-19 patients, who have recovered, could lose their immunity to the disease within months and that the virus could reinfect people year after year, like common colds, scientists say.

The study examined more than 90 patients and healthcare workers at Guy’s and St Thomas’ NHS foundation trust and found levels of antibodies that can destroy the virus peaked about three weeks after the onset of symptoms then swiftly declined, reports The Guardian.

Besides, 60 percent of people marshalled a “potent” antibody response at the height of their battle with the virus, said the study after …….
