Dinosaur DNA found preserved in 75 million year-old fossil

Scientists have discovered organic material preserved in 75-million-year-old dinosaur fossils, including cartilage cells, proteins, chromosomes, and DNA. Researchers from the Chinese Academy of Sciences in Beijing and North Carolina University in the US published a paper on National Science Review detailing the discovery. The organic material was found within the skull fragment of a Hypacrosaurus, a type of duckbill dinosaur. The research took a close look at two juvenile skull bones from the plant-eating dinosaur that lived in what is now called Montana about 75 million years ago. Inside the tiny fossils, researchers observed cells, some of which appeared to have frozen in the process of cell division, reports National Geographic quoting the study. They have also observed what ap...

Australian scientists make breakthrough on preventing spread of dengue fever

Researchers from Australia’s national science body have successfully genetically engineered mosquitoes that are resistant to spreading dengue virus. The Commonwealth Scientific and Industrial Research Organisation (CSIRO) on Friday revealed that it has engineered the first breed of mosquitoes resistant to spreading all four types of the dengue virus. Dengue fever is a mosquito-borne disease caused by the dengue virus. It affects 390 million people every year around the world and can cause death if left untreated, according to CSIRO. Prasad Paradkar, a Senior Research Scientist with the CSIRO, said that the disease is at epidemic levels in tropical and subtropical regions worldwide, with outbreaks currently occurring in Bangladesh, Pakistan, Sri Lanka and the Philippines. “There is...

First Iranian-American astronaut reaches for stars

Jasmin "Jaws" Moghbeli earned her fierce nickname during her time as a decorated helicopter gunship pilot who flew more than 150 missions in Afghanistan. The Marine Corps major, MIT graduate and college basketball player can now add another accomplishment to her burgeoning resume: the first Iranian-American astronaut. Speaking to AFP after graduating in NASA's latest cohort, the 36-year-old immigrant said she hoped her example might help inspire others from similar backgrounds. "I would love for everyone to be able to be inspired by everyone, but it is a little easier to be inspired by someone who looks like you or has something in common with you, so I do hope there is that influence," she said. She and her brother were born in Germany to Iranian parents, architecture students wh...

Pioneers of lithium-ion battery win 2019 Nobel chemistry prize

Scientists John Goodenough, Stanley Whittingham and Akira Yoshino won the 2019 Nobel Prize for Chemistry today for the development of lithium-ion batteries, an important technology in enabling the world to move away from fossil fuels. American Goodenough, at 97, becomes the oldest winner of a Nobel prize. He shared the award equally with Whittingham from Britain and Yoshino of Japan. "This rechargeable battery laid the foundation of wireless electronics such as mobile phones and laptops," the Royal Swedish Academy of Sciences said in a statement on awarding the 9 million Swedish crown ($906,000) prize. "It also makes a fossil fuel-free world possible, as it is used for everything from powering electric cars to storing energy from renewable sources." Whittingham developed the first...

Peebles, Mayor, Queloz win Nobel physics prize for discoveries in astronomy

Canadian-American cosmologist James Peebles and Swiss scientists Michel Mayor and Didier Queloz won the 2019 Nobel Prize for Physics today for shedding light on the evolution of the universe and discovering planets orbiting distant suns. Peebles, of Princeton University in the United States, was awarded half the 9-million-Swedish-crown ($910,000) prize while Mayor and Queloz, from the University of Geneva in Switzerland, shared the other half. "This year's Laureates have transformed our ideas about the cosmos," the Royal Swedish Academy of Sciences said in a statement accompanying the award.

3 scientists of UK, US win Nobel Prize in Medicine

Two scientists from the United States and one from Britain won the 2019 Nobel Medicine Prize today for finding how cells adapt to fluctuating oxygen levels, paving the way for new strategies to fight diseases such as anaemia and cancer. The Nobel award-giving body said US-born researchers William Kaelin and Gregg Semenza shared the prize equally with Peter Ratcliffe, who was born in Britain. "The seminal discoveries by this year's Nobel laureates revealed the mechanism for one of life's most essential adaptive processes," the Nobel Assembly at Sweden's Karolinska Institute said in a statement on awarding the prize of 9 million Swedish crowns ($913,000). Their research established the basis for the understanding of how oxygen levels affect cellular metabolism and physiological func...

PM opens TV channels’ broadcast using Bangabandhu-1 satellite

Prime Minister Sheikh Hasina today inaugurated the commercial transmission of all local private television channels using the feed of country’s first communication satellite Bangabandhu-I (BS-I) as she addressed a function on the occasion at a city hotel. With its inauguration, the country’s broadcast industry is going to enter a new era as the BS-I will save a huge amount of foreign currency to be paid by local TVs as rent. Information Minister Dr Hasan Mahmud spoke on the occasion as the special guest with Posts and Telecommunications Minister Mustafa Jabbar in chair. Secretary of Posts and Telecommunications Division Ashoke Kumar Biswas and Chairman of the Association of Television Channel Owners (ATCO), a platform of private television channel owners, Anjan Chowdhury also spok...
