X-ray images of ancient ‘Bisti Beast’ dinosaur skull reveal how ‘bone crushing adaptations’ arose in the T. rex family

Researchers have imaged a 74-million-year-old dinosaur skull in the highest-resolution scan of a tyrannosaur skull ever done.

The skull belonged to a ‘Bisti Beast,’ a relative of the Tyrannosaurus rex with big-headed, bone-crushing adaptations.

The scan revealed un-erupted teeth, the brain cavity, and sinus cavities. It added a new piece to the puzzle of how these predators evolved over millions of years.

The researchers used neutron-imaging and high-energy x-rays to conduct the scan. These techniques have revolutionized the study of paleontology over the past ten years, allowing scientists to gain insights into the anatomy and developments of ancient species.

This dinosaur skull was initially discovered in the Bisti Badlands in northwestern New Mexico in 1996.

‘It’s a tyrannosaur – it’s a relative of Tyrannosaurus rex, but it’s a dinosaur that lived about 10 million years before T.rex, about 74 million years ago,’ said Dr Thomas Williamson, Curator of Paleontology at the New Mexico museum.

The results of the scan helped the team determine the skull’s sinus and cranial structure.

Usain Bolt posts X-ray of torn hamstring

Last week, the king of sprinting fell to the track during his final race at the World Athletics Championships.

On Twitter, Bolt explained the extent of his injury.

He said: “Sadly I have a tear of the proximal myotendineous junction of biceps femoris in my left hamstring with partial retraction. Three months rehab.

“I don’t usually release my medical report to the public but sadly I have sat and listened to people questioning if I was really injured.

“I have never been one to cheat my fans in any way and my entire desire at the Championships was [to] run one last time for my fans.

“Thanks for the continued support my fans and I rest, heal and move onto the next chapter of my life.”

You’re amazing, Usain, and we wish you a speedy recovery and incredible next chapter of your life.

Pro surfer Kelly Slater shares X-ray of gruesome foot injury on Instagram

And again we say…hooray for x-rays!

kelly-sltear.jpgLast month, 11-time World Surf League champion Kelly Slater was forced to call his run at Jeffreys Bay short Monday after suffering a devastating broken foot.

Later that day, Slater showed his impressive break on Instagram and announced his official withdrawal from the competition. He described the injury as “kinda like smashing my foot with a big hammer as hard as I can. Sorta feels like I’m giving birth out of my foot right now!”

Check out the x-ray of his injury below. Wishing you a speedy recovery, Slater!

Cubs Champion Kris Bryant Escapes Serious Finger Injury

screen-shot-2017-07-19-at-12-36-24-pm.png

Reigning National League MVP Kris Bryant certainly scared the Cubs organization when he had to leave Wednesday’s game after jamming his finger on the foot of the Braves’ third baseman sliding head-first.

Thanks to x-rays, Bryant was quickly diagnosed with a sprain between the left pinky and ring fingers. His playing status will be evaluated again on Friday after a rest day on Thursday.

“I think we kind of dodged a bullet there,” manager Joe Maddon said. “I don’t think it’s debilitating. He heals quickly, as we’ve seen with the [turned] ankle [last month]. I don’t anticipate a long process here.”

“You slide into someone’s foot, and you obviously think the worst-case scenario,” Bryant said. “I was kind of scared to even look at my finger afterward. It was like, ‘Uh-oh, this never ends up good.’

Bryant, who had the two fingers taped together after the game, said he became more optimistic even before the x-rays, when the trainer examined him.

He said he hoped his off day on Thursday would make the difference.

Tommy La Stella replaced Bryant defensively at third to start the bottom of the first.

Bryant was 8-for-23 (.348) with a homer and three walks during the Cubs’ 6-0 sweep during their road trip through Baltimore and Atlanta. The six-game streak is their longest of the year.

X-Ray Reveals What Doctor’s Couldn’t See

A 23-year-old woman was admitted to hospital complaining of an ‘uncomfortable sensation’ in her throat the other day.

Doctors were originally left stumped by the woman’s symptoms, as she was able to breath normally and there were no signs that her airways were blocked.

But an x-ray saw what they couldn’t. There was a 1.2 inch fishbone jammed in the soft tissue of her esophagus. She had eaten cod earlier that day, and the bone got stuck.

Doctors were able to remove the bone from her throat the next day in a surgical procedure.

Dr McCabe said: ‘The patient was subsequently brought to the operating theatre the next day by the ENT surgical team, whereby the foreign body was identified and removed from the upper oesophagus via direct visualisation with a flexible endoscope.’

The patient is now just fine- thanks to the power of x-rays!

Sinus X-rays reveal age of children

frontal-sinus-child-age-1.jpg

Anthropologists, pathologists and other scientists may soon have a new tool to work with when it comes to determining the age of deceased children based on their skeletal remains. Researchers in North Carolina have discovered that the frontal sinus of the skull undergoes distinct changes throughout childhood, and those changes can be matched up to approximate ages.

The scientists analyzed X-rays of almost 400 people of known ages, between infancy and 18 years old, in order to establish the different stages of development.

From here they were able to categorize different stages including less than six years old, between six and eight, between seven and ten, and between 12 and 18. In each stage, there are different skull developments.

 

“This is a proof-of-concept study demonstrating that frontal sinus X-rays offer a viable, noninvasive technique for estimating the age range of juvenile remains,” says Ross, who led the study. “This approach should be particularly valuable when working with incomplete remains.”

That said, the technique could also be used to ascertain the age of living children for which there are no birth records.

The First X-Ray Photograph

Today we’re winding the clock back, all the way back to 1895.

That’s right: December 1895, when Wilhelm Röntgen revealed the bones of his wife’s hand in the first X-ray photograph.

Luckily, x-rays have come pretty far in the past hundred plus years. At the time, Röntgen’s wife Anna Bertha Ludwig reportedly exclaimed, “I have seen my death” after seeing the x-ray photo with her wedding ring hovering over her knuckles.

That ability to see within the body without surgery radically improved the life-saving capabilities of medicine in the 20th century. Röntgen went on to receive the Nobel Prize in 1901.
