  • The dinosaur’s fossils were found in southern Argentina in 2012

  • A cast of the dinosaur’s skeleton is on display at the American Museum of Natural History

USA, August 10, 2017: A study proclaims a newly named species the heavyweight champion of all dinosaurs, making the scary Tyrannosaurus rex look like a munchkin.

At 76 tons (69 metric tons), the plant-eating behemoth was as heavy as a space shuttle.

The dinosaur’s fossils were found in southern Argentina in 2012. Researchers who examined and dated them said the long-necked creature was the biggest of a group of large dinosaurs called titanosaurs.

“There was one small part of the family that went crazy on size,” said Diego Pol of the Egidio Feruglio paleontology museum in Argentina, co-author of the study published Tuesday in the journal Proceedings of the Royal Society B.

The researchers named the dinosaur Patagotitan dinosaur Patagotitan mayorum after the Patagonia region where it was found and the Greek word titan, which means large. The second name honors a ranch family that hosted the researchers.

Six fossils of the species were studied and dated to about 100 million years ago, based on ash found around them, Pol said. The dinosaur averaged 122 feet long (37 meters) and was nearly 20 feet high (6 meters) at the shoulder.

A cast of the dinosaur’s skeleton is on display at the American Museum of Natural History. It’s so big that the dinosaur’s head sticks out into a hallway at the New York museum.

Legendary T. rex and other meat-eaters “look like dwarfs when you put them against one of these giant titanosaurs,” Pol said. “It’s like when you put an elephant by a lion.”

Scientists have known titanosaurs for a while, but this is a new species and even a new genus, which is a larger grouping, Pol said. Another titanosaur called Argentinosaurus was previously thought to be the largest.

“I don’t think they were scary at all,” Pol said. “They were probably massive, big, slow-moving animals.”

“Getting up. Walking around. Trying to run. It’s really challenging for large animals,” he said.

The big question is how did these dinosaurs get so big, Pol said. Researchers are still studying it but said it probably has to do with an explosion of flowering plants at the time. Along with a forest, it was like an all-you-can-eat buffet for these dinosaurs and they just got bigger.

“It’s hard to argue this isn’t a big deal when it concerns the [probable] largest land animal ever discovered,” University of Maryland paleontologist Thomas Holtz, who wasn’t part of the study, said in an email.

Kristi Curry Rodgers, a paleontologist at Macalester College who wasn’t part of the study, praised the work as important. She said the fact that Patagotitan’s bones show signs that they haven’t completed their growth “means that there are even bigger dinosaurs out there to discover.” (VOA)

  • The latest research suggests that the modern apples originated from Kazakhstan
  • The study was carried out by researchers from Boyce Thompson Institute in the United States
  • It was the genetic exchange from traders who used the Silk Road that the modern apples emerged in Kazakhstan

US, August 17, 2017: A new study suggests that the modern apples that are so crisp, yet so juicy, actually originated from Kazakhstan 10,000 years ago.

The study by researchers at Boyce Thompson Institute (BTI) in the US reveal that during the back and forth traveling by traders on the Silk Road, the genetic exchange occurred that led to the emergence of modern day apples in Kazakhstan’s mountainous regions. Malus Domestica is the scientific name for our modern domesticated apples.

The Silk Road connected the East to the West. Hence, it led to an exposure of knowledge and ideas. Researchers hypothesize that this exchange of ideas resulted in the birth of the tasty Malus Domestica.

Lead Author of the study and Professor at Boyce Thompson Institute, Zhangjun Fei, explains his team’s study which is published in the journal Nature Communications.

To carry out the study, the team of researchers sequenced 117 different apples and compared their genomes. These included the wild species extracted from Europe, North America, Central and East Asia.

The birth of the modern apples ultimately led to 7,500 varieties of the fruit. Interestingly, the quality of the fruit changed as from region to region as it first traveled from the East to the West. When the apples returned to go back to the west, the dropped seeds on the way helped the growth of trees in wild places.

M Sylvestris was dominant in the Apple’s growth. It’s ancestor, M Sieversii is found predominantly in Kazakhstan.

Our modern day apples have well-balanced sugar and higher organic acid contents. Hence, it is no wonder now that Apple is one of the favorite fruits for many people.

  • The device called Tissue Nanotransfection (TNT) does not require any laboratory-based procedures and may be implemented at the point of care
  •  It instantly delivers new DNA or RNA into living skin cells to change their function
  • The team conducted experiments on mice and pigs, where they reprogrammed skin cells to become vascular cells in badly injured legs that lacked blood flow

August 9, 2017: Researchers, led by one of the Indian-origin, have developed a new device that can non-invasively convert skin cells into elements of any organ with a single touch, a finding that may help repair injured tissues, blood vessels, and nerves.The device called Tissue Nanotransfection (TNT) does not require any laboratory-based procedures and may be implemented at the point of care.

 It instantly delivers new DNA or RNA into living skin cells to change their function, with a small electrical charge that’s barely felt by the patient, thus aiding the speedy repair of injured tissue as well as restoring the function of ageing tissue, including organs.

“With this nano chip technology, we can convert skin cells into elements of any organ with just one touch. This process only takes less than a second and is non-invasive, and then you’re off. The chip does not stay with you, and the reprogramming of the cell starts,” said Chandan Sen, Director at The Ohio State University in the US.

For the study, published in the journal Nature Nanotechnology, the team conducted experiments on mice and pigs, where they reprogrammed skin cells to become vascular cells in badly injured legs that lacked blood flow. Within one week, active blood vessels appeared on the injured leg and by the second week, the leg was saved.

In lab tests, the technology was also shown to reprogram skin cells in the live body into nerve cells that were injected into brain-injured mice to help them recover from the stroke, the researchers said.

“This is difficult to imagine, but it is achievable, successfully working about 98 per cent of the time,” Sen said, adding the researchers plan to start clinical trials next year in humans. (IANS)

Catastrophic Maternal Healthcare expenses push 47 percent Mothers in India into Poverty: Researchers

May 22, 2017: Catastrophic maternal healthcare expenses push 46.6 per cent mothers in India into poverty — with the illiterate being especially susceptible — according to a December 2016 study by researchers from Jawaharlal Nehru University (JNU) and Indian Institute of Technology, Roorkee (IIT-R). The expenses include childbirth, antenatal care and postnatal care expenses.

Catastrophic expenditure is greater than or equal to 40 percent of a household’s non-subsistence income, i.e. income available after basic needs have been met, according to the World Health Organisation (WHO). The threshold of 40 per cent can differ according to countries, said the WHO; the 2016 study has analyzed the data at two thresholds: 10 and 40 per cent.

NewsGram brings to you latest new stories in India.

As many as 63 per cent households nationwide had a catastrophic maternal health expenditure of 40 per cent, the study — which analysed data from the National Sample Survey Office — found. Among states and Union territories (UTs), 65.7 per cent households (among those where a woman had delivered) in Telangana were pushed into poverty — more than any other state/UT — due to childbearing expenses, followed by Chhattisgarh (53.7 per cent) and Puducherry (53.4 per cent).

In the 10 years to 2014, out-of-pocket (OOP) health spending has pushed 50.6 million people back into poverty.

Households where the mothers were illiterate were the most affected, with 61 per cent of them being pushed into poverty –despite having the lowest maternal health OOP expenditure at Rs 3,600 — compared to 36.7 per cent of households where women were graduates and above, who had an OOP expenditure of Rs 19,250.

More illiterate women prefer public hospitals for delivery in both rural (79.2 per cent) and urban areas (67.7 per cent), which possibly explains their low OOP.

Among women of different social groups, women belonging to scheduled tribes (STs) had the least maternal OOP expenditure at Rs 2,962, but 71.5 per cent of them were pushed into poverty. As many as 85 per cent ST women in rural areas delivered in public hospitals — more than any other social group.

The study holds relevance in the context of the central government announcement on May 18, 2017, that it is revising the Indira Gandhi Matritva Sahyog Yojana (Maternity Benefit Programme), announced by Prime Minister Narendra Modi on December 31, 2016, by restricting the scheme to firstborns instead of “first two live births” as applicable earlier.

The programme aims to give Rs 6,000 to pregnant women for childbearing expenses. The scheme saw an increase of 226 per cent in allocation in the 2017-18 budget from Rs 634 crore to Rs 2,700 crore. However, the government had estimated that the annual requirement for the maternity benefit scheme would be Rs 14,512 crore, according to a report in The Indian Express.

Look for latest news from India in NewsGram.

The 2016 study revealed that, on average, a woman incurred an OOP expenditure of Rs 8,543 on childbearing. There were huge variations among states — from Rs 2,801 in Uttarakhand to Rs 15,433 in Telangana.

“The most vulnerable women who are trying to reach out for the government aid won’t be able to get it,” Tania Sheshadri, an independent community health researcher who works with rural women in Karnataka, was recently quoted as saying in news reports.

“In most parts of the country, there is a two-child norm and a scheme like this will not benefit most women. The government should concentrate on quality care for pregnant women and make available the benefits to every woman who reaches a government health care centre.”

A limitation of the 2016 study is that it does not consider the benefits of Janani Suraksha Yojana (JSY, motherhood protection scheme), a 12-year-old government programme focused specially on 10 states with low rates of institutional delivery — Uttar Pradesh, Uttarakhand, Bihar, Jharkhand, Madhya Pradesh, Chhattisgarh, Assam, Rajasthan, Odisha, and Jammu and Kashmir — termed as low-performing states (LPS).

Under the programme, pregnant women in rural areas who live below the poverty line are to be given cash assistance — Rs 700 in high performing states and Rs 1,400 in LPS — irrespective of the mother’s age and number of children so that they opt for birth in a government or accredited private health facility.

The scheme has failed to cover the poorest women, according to a 2014 analysis of JSY data by researchers from Georgetown University. As many as 60 per cent women in Uttar Pradesh said they had to pay for certain public maternal health services, according to an assessment of JSY conducted by United Nations Population Fund in Bihar, Madhya Pradesh, Odisha, Rajasthan and Uttar Pradesh in 2012.
