Texas man pleads guilty to trying to smuggle people in flag-draped coffin
GALVESTON, Texas — A Galveston man entered a guilty plea in federal court on charges that he tried to smuggle people into the United States using a flag-draped coffin. >> Read more trending newsThe U.S. Department of Justice announced the plea, under which Zachary Taylor Blood admitted to one count of alien smuggling. Investigators said on Oct. 26, 2021, Blood drove a gray van to a Border Patrol checkpoint near Falfurrias, Texas. After crossing the river into the United States, they met Blood in a parking lot, where he was waiting for them and had them hide in the coffin. Blood faces up to five years in federal prison and up to $250,000 in fines when he is sentenced in May, KTRK reported.wftv.com
China launches cargo rocket with supplies for space station
A Long March 7 rocket carrying the Tianzhou-2 took off at 8:50 p.m. (1250 GMT) from the Wenchang launch center on Hainan Island, the official Xinhua News Agency reported. The Tianzhou-2 carried fuel and supplies for the Tianhe space station, state media reported earlier. The Chinese space agency says 11 launches are planned through the end of next year to deliver two more modules for the 70-ton space station, supplies and its three-member crew.news.yahoo.com
The secrets of human chromosomes have not yet been cracked by scientists, study suggests
Scientists have finally weighed a full set of human chromosomes and discovered they are 20 times heavier than expected - declaring there could be "missing components". Researchers told the Sunday Telegraph they have no idea as to what that may be. Chromosomes are bundles of genetic material which exist inside almost every cell of all complex lifeforms, from bacteria to humans and everything in between. Most humans have 46 chromosomes — 23 pairs — all of different size and shape, but other species have varying numbers. For example, possums have just 22, foxes have 34 and a great white shark has 82. But Atlas blue butterflies have around 450 and the Adder’s tongue fern has a staggering 1,440. But regardless of number or organism, all chromosomes follow the same basic structure. Individual bases of DNA, called A, G, C and T, pair up and form short, double helix-shaped chains which wrap around a ball of eight proteins to create bundles called nucleosomes. These little packages of genetic material are joined to one another by a thin piece of connective material, and experts refer to them as ‘beads on a string’. But while we know all this, and that the complete copy of a human genome contains more than 6.4billion base pairs of DNA, the exact and total mass of our chromosomes has never been known. Scientists from UCL used a powerful X-ray beam in Didcot, Oxfordshire, called Diamond, to weigh a complete set of human chromosomes for the first time. The researchers bombarded individual chromosomes with X-rays and assessed how much the beam scattered. This diffraction pattern was used to produce a 3D reconstruction of the chromosome’s structure. The brightness of the Diamond machinery, which outshines the Sun by billions of times, allowed for a highly detailed image. Professor Robinson and colleagues published their paper in the journal Chromosome Research and found the mass of all 46 human chromosomes to be 242 picograms. The heaviest is chromosome 1, which is also the largest, and it weighs 10.9 picograms. One picogram is a trillionth of a gram and a grain of sand weighs approximately 0.000000004 picograms. A red blood cell, which does not have a nucleus and therefore is devoid of genetic material, weighs around 27 picograms. “There may be quite a lot of missing components to our chromosomes that are yet to be discovered,” Professor Ian Robinson, senior author of the new study from UCL, told The Sunday Telegraph: “Chromosomes have been investigated by scientists for 130 years but there are still parts of these complex structures that are poorly understood.” He went on: "The mass of DNA we know from the Human Genome Project, but this is the first time we have been able to precisely measure the masses of chromosomes that include this DNA. “Our measurement suggests the 46 chromosomes in each of our cells weigh 242 picograms. “This is heavier than we would expect, and, if replicated, points to unexplained excess mass in chromosomes.” In order to accurately measure the chromosomal mass, the researchers blasted them with X-rays when the cells were in metaphase, before they underwent the splitting process. Scientists are constantly trying to learn more about the human body, and the mapping of the genome was a key step in that. However, this study lays bare the fact there is still a long way to go before we fully understand the nuances of our own body. Archana Bhartiya, a PhD student at the London Centre for Nanotechnology at UCL and lead author of the paper, said: “A better understanding of chromosomes may have important implications for human health. “A vast amount of study of chromosomes is undertaken in medical labs to diagnose cancer from patient samples. “Any improvements in our abilities to image chromosomes would therefore be highly valuable.”news.yahoo.com
Type O blood may mean lower COVID-19 risk
It’s starting to look like people with the O blood type may have an advantage in the global pandemic. A Danish study found among more than 470,000 people tested for coronavirus, only 38% with blood type O tested positive, even though 41% of the population have type-O blood. [TRENDING: Woman stranded from home for 8 months | Video shows mountain lion stalking hiker | Moon rules: Must come in peace]A Canadian study found among 95 patients critically ill with COVID-19, a higher proportion with blood type A or A/B needed mechanical ventilation compared with patients with blood group O or B. The research gives further evidence blood type may play a role in someone’s susceptibility to infection and just how serious their illness is. The reasons for this link aren’t clear and experts say more research is needed.
Demand for plasma, blood donations remains high as pandemic rages
Orange County’s EMS Medical Director Dr. Christian Zuver spoke about his experience donating plasma after he recovered from COVID-19. “Many of the places where you would normally see blood drives – like high schools, college campuses and companies – are not at a point where they can host regular blood drives,” officials said. The need for blood and plasma is more urgent than it has ever been in recent history. “We live in a caring community and donating convalescent plasma is just one of those ways we can continue to help each other,” added Zuver. To donate convalescent plasma or blood, officials ask that you make an online appointment at OneBlood.org.

U.S. may see blood shortages as coronavirus cancels office blood drives
NEW YORK (Reuters) - U.S. blood banks are concerned about potential shortages as Americans concerned about catching the new coronavirus avoid donation sites and companies with employees working from home cancel blood drives. Blood has a short shelf life, so its not like we can stockpile it.Most blood centers try to keep an inventory of a three-day supply, according to the AABB. Finson said 60% of Bloodworks Northwests blood is from mobile blood drives, and the push to have people work from home has resulted in many being canceled. He is encouraging individuals and sponsors of blood drives to schedule appointments and keep their commitments, and that blood banks around country can continue to shift supply to where it is needed. In Seattle, Finson said donations picked up over the weekend, but on Tuesday, Bloodworks Northwest was around 140 short of its 1,000 donor-per-day target.feeds.reuters.com
