Researchers create first sensor package that can ride aboard bees.




Researchers at the University of Washington have created a sensor package that is small enough to ride aboard a bumblebee.

Farmers can already use drones to soar over huge fields and monitor temperature, humidity or crop health. But these machines need so much power to fly that they can’t get very far without needing a charge.

Now, engineers at the University of Washington have created a sensing system that is small enough to ride aboard a bumblebee. Because insects can fly on their own, the package requires only a tiny rechargeable battery that could last for seven hours of flight and then charge while the bees are in their hive at night.

“Drones can fly for maybe 10 or 20 minutes before they need to charge again, whereas our bees can collect data for hours,” said senior author Shyam Gollakota, an associate professor in the UW’s Paul G. Allen School of Computer Science & Engineering. “We showed for the first time that it’s possible to actually do all this computation and sensing using insects in lieu of drones.”

Among invaluable artifacts that were saved, which one is considerable as a relic? (Text Comprehension)

A fire gutted parts of Notre Dame Cathedral and altered the Paris skyline


Paris (CNN) A catastrophic fire engulfed Notre Dame Cathedral in Paris on Monday, altering the city's skyline and threatening a potent symbol of Catholicism at the start of Holy Week.

The fire burned for several hours, destroying the 850-year-old cathedral's iconic spire and roof before firefighters contained the blaze early Tuesday morning.

A pair of bell towers immortalized in Victor Hugo's tale "The Hunchback of Notre Dame" survived, along with the cathedral's elaborate stonework facade. Officials said invaluable artifacts were saved, including the Crown of Thorns, believed to be a relic of the passion of Christ.

President Emmanuel Macron lamented the destruction of an awe-inspiring building that embodied the heart of Paris for more than 800 years. But he pledged to rebuild, starting with the launch of an international fundraising campaign.

"Notre Dame is our history, it's our literature, it's our imagery. It's the place where we live our greatest moments, from wars to pandemics to liberations," he said.

"This history is ours. And it burns. It burns and I know the sadness so many of our fellow French feel."
The Paris prosecutor opened an investigation into the fire, the cause of which is still unknown.


Hundreds of firefighters were deployed to the scene, snarled by rush hour traffic.

For much of the afternoon, flames and plumes of smoke billowed from the cathedral as firefighters in cranes sprayed water onto the structure. 

The cathedral was undergoing renovation work, the fire service said.

'Madness'
The fire, just days before Easter, was met with horror by Parisians and tourists.

As firefighters battled the blaze, Parisians gathered outside the church Monday night, raising their voices in prayer.

"It's awful to see such a symbol disappearing in front of you. It's been there for so many years and in a few minutes half of it disappeared ... crazy.

"Paris without Notre Dame, madness."

Should we relax about screen time?

The UK government's plans for regulation of the internet and social media contained a long list of online harms. Among them was excessive screen use by teenagers.



On the Tech Tent podcast this week, we ask whether there is convincing evidence that spending hours staring at smartphones and other screens is damaging the mental health of young people.

f you read news headlines - or indeed the government's Online Harms White Paper - you might think that the case against screen time was a no-brainer. But this week, a study by the Oxford Internet Institute suggested that it had little obvious effect on the mental wellbeing of teenagers, even if they were spending hours staring at screens at bedtime.

"We look at general wellbeing," one of the researchers, Amy Orben, tells us. "We do not find a relationship between digital screen use 30 minutes, one hour and two hours before bed and a decrease in wellbeing."

“Patel`s team gave diluted alcohol to mice.” (Passive Voice)

How alcohol damages stem cell DNA and increases cancer risk.




LONDON (Reuters) - Drinking alcohol produces a harmful chemical in the body which can lead to permanent genetic damage in the DNA of stem cells, increasing the risk of cancer developing, according to research published on Wednesday.

Working with mice in a laboratory, British scientists used chromosome analysis and DNA sequencing to examine the genetic damage caused by acetaldehyde, a harmful chemical produced when the body processes alcohol.

Their findings offered more detail about how alcohol increases the risk of developing 7 types of cancer, including common forms such as breast and bowel cancer. It also showed how the body seeks to defend against the damage alcohol can do.“Some cancers develop due to DNA damage in stem cells. While some damage occurs by chance, our findings suggest that drinking alcohol can increase the risk of this damage,” said Ketan Patel, a professor at the Medical Research Council Laboratory of Molecular Biology, who co-led the study. The World Health Organization’s International Agency for Research on Cancer classifies alcohol as a Group 1 carcinogen, citing “convincing evidence” it causes cancer in humans.

In Wednesday’s study, published in the journal Nature, Patel’s team gave diluted alcohol to mice and then analyzed the effect on the animals’ DNA. They found that acetaldehyde can break and damage DNA within blood stem cells, permanently altering the DNA sequences within these cells.

This is important, Patel said, because when healthy stem cells become faulty, they can give rise to cancerous cells.

Which statement is considered incorrect or false in the text above. (Text Comprehension)

First ever black hole image released.

Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy. It measures 40 billion km across - three million times the size of the Earth - and has been described by scientists as "a monster".

The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world It was captured by the Event Horizon Telescope (EHT), a network of eight linked telescopes. 

Prof Heino Falcke, of Radboud University in the Netherlands, who proposed the experiment, told BBC News that the black hole was found in a galaxy called M87.

"What we see is larger than the size of our entire Solar System," he said.

"It has a mass 6.5 billion times that of the Sun. And it is one of the heaviest black holes that we think exists. It is an absolute monster, the heavyweight champion of black holes in the Universe."

The image shows an intensely bright "ring of fire", as Prof Falcke describes it, surrounding a perfectly circular dark hole. The bright halo is caused by superheated gas falling into the hole. The light is brighter than all the billions of other stars in the galaxy combined - which is why it can be seen at such distance from Earth.

The edge of the dark circle at the centre is the point at which the gas enters the black hole, which is an object that has such a large gravitational pull, not even light can escape.

The image matches what theoretical physicists and indeed, Hollywood directors, imagined black holes would look like, according to Dr Ziri Younsi, of University College London - who is part of the EHT collaboration.

"Although they are relatively simple objects, black holes raise some of the most complex questions about the nature of space and time, and ultimately of our existence," he said.

"It is remarkable that the image we observe is so similar to that which we obtain from our theoretical calculations. So far, it looks like Einstein is correct once again."

But having the first image will enable researchers to learn more about these mysterious objects. They will be keen to look out for ways in which the black hole departs from what's expected in physics. No-one really knows how the bright ring around the hole is created. Even more intriguing is the question of what happens when an object falls into a black hole.

“The scale of devastation is enormous. (Synonym)

Mozambique Cyclone: “Almost everything is destroyed.”



People carry their personal effects through a flooded section of Praia Nova in Beira after the cyclone. Tropical Cyclone Idai destroyed and damaged homes and knocked out electricity and communications.


Cyclone Idai hit the city of Beira hard and the scale of damage is massive, say Red Cross and Red Crescent aid workers who reached the Mozambican city a few days ago. The scale of devastation is enormous. It seems that 90 per cent of the area is completely destroyed.”

The Red Cross and Red Crescent team was among the first to arrive in Beira since Cyclone Idai made landfall March 14-15. With Beira’s airport closed and roads cut off due to flooding, the team drove from Maputo, the capital city, before taking a helicopter for the last leg of the journey. “Almost everything is destroyed. Communication lines have been completely cut and roads have

been destroyed. Some affected communities are not accessible,” said LeSueur. “Beira has been severely battered. But we are also hearing that the situation outside the city could be even worse. Yesterday, a large dam burst and cut off the last road to the city.”

While the physical impact of Idai is beginning to emerge, the human impact is still unclear. Authorities in the country are warning that the death toll may climb beyond 1,000 people.

Heavy rain will continue in the coming days which may only exacerbate the dire situation and cause already saturated rivers to overflow.

Following its landfall in Mozambique, the cyclone continued west to Zimbabwe as a tropical storm, wreaking havoc in the eastern part of the country, with Manicaland Province being the hardest-hit. At least 31 deaths have been reported and over 100 people are missing in Zimbabwe.
