Newswise — Cornell bioengineers and physicians have created an artificial ear – using 3-D printing and injectable molds – that looks and acts like a natural ear, giving new hope to thousands of children born with a congenital deformity called microtia.

In a study published online Feb. 20 in PLOS One, Cornell biomedical engineers and Weill Cornell Medical College physicians described how 3-D printing and injectable gels made of living cells can fashion ears that are practically identical to a human ear. Over a three-month period, these flexible ears grew cartilage to replace the collagen that was used to mold them.

“This is such a win-win for both medicine and basic science, demonstrating what we can achieve when we work together,” said co-lead author Lawrence Bonassar, associate professor of biomedical engineering.

The novel ear may be the solution reconstructive surgeons have long wished for to help children born with ear deformity, said co-lead author Dr. Jason Spector, director of the Laboratory for Bioregenerative Medicine and Surgery and associate professor of plastic surgery at Weill Cornell in New York City.

“A bioengineered ear replacement like this would also help individuals who have lost part or all of their external ear in an accident or from cancer,” Spector said.
Replacement ears are usually constructed with materials that have a Styrofoam-like consistency, or sometimes, surgeons build ears from a patient’s harvested rib. This option is challenging and painful for children, and the ears rarely look completely natural or perform well, Spector said.

To make the ears, Bonassar and colleagues started with a digitized 3-D image of a human subject’s ear, and converted the image into a digitized “solid” ear using a 3-D printer to assemble a mold.

This Cornell-developed, high-density gel is similar to the consistency of Jell-o when the mold is removed. The collagen served as a scaffold upon which cartilage could grow.

The process is also fast, Bonassar added: “It takes half a day to design the mold, a day or so to print it, 30 minutes to inject the gel, and we can remove the ear 15 minutes later. We trim the ear and then let it culture for several days in nourishing cell culture media before it is implanted.” Read the rest at Using 3-D Printing and Injectable Molds, Bioengineered Ears Look and Act Like the Real Thing.


FEB. 21 – JQA & the Bible

American Minute with Bill Federer

FEB. 21 – JQA & the Bible

On FEBRUARY 21, 1848, John Quincy Adams suffered a stroke at his desk in the House chamber, shortly after making an impassioned speech against the Democrat plan of extending slavery to the Western territories acquired after the Mexican-American War.He died 2 days later without regaining consciousness.

A bronze marker on the U.S. House floor indicates where Adams’ desk once stood.

John Quincy Adams was the only U.S President to serve in Congress after having been President.

Nicknamed ‘Old Man Eloquent’ for speaking out against slavery, he offered a plan for its elimination.In a Supreme Court case, 1841, John Qunicy Adams defended and won freedom for 53 Africans who had mutinied aboard the slave shipAmistad.

African slaves were purchased at Muslim slave markets and brought to the Americas.

The annotated John Quincy Adams-A Bibliography, compiled by Lynn H. Parsons (Westport, CT, 1993, p. 41, entry#194), contains “Unsigned essays dealing with the Russo-Turkish War and on Greece,” (The American Annual Register for 1827-28-29 (NY: 1830):

“The natural hatred of the Mussulmen towards the infidels is in just accordance with the precepts of the Koran…

The fundamental doctrine of the Christian religion is the extirpation of hatred from the human heart. It forbids the exercise of it, even towards enemies…

In the 7th century of the Christian era, a wandering Arab…spread desolation and delusion over an extensive portion of the earth…

He declared undistinguishing and exterminating war as a part of his religion…The essence of his doctrine was violence and lust, to exalt the brutal over the spiritual part of human nature.”


On September 26, 1810, John Quincy Adams wrote in his diary:

“I have made it a practice for several years to read the Bible through in the course of every year. I usually devote to this reading the first hour after I rise every morning…

I have this morning commenced it anew…this time with Ostervald’s French translation.”

In September of 1811, John Quincy Adams wrote to his son from St. Petersburg, Russia:

“My dear Son…You mentioned that you read to your aunt a chapter in the Bible or a section of Doddridge’s Annotations every evening. This information gave me real pleasure; for so great is my veneration for the Bible

It is of all books in the world, that which contributes most to make men good, wise, and happy… My custom is, to read four to five chapters every morning immediately after rising from my bed…

It is essential, my son…that you should form and adopt certain rules…of your own conduct… It is in the Bible, you must learn them…

‘Thou shalt love the Lord thy God, with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength, and thy neighbor as thy self.’ On these two commandments, Jesus Christ expressly says, ‘hang all the law and the prophets’.”

John Quincy Adams’ correspondence to his son is compiled in Letters of John Quincy Adams to his son, on the Bible and its Teachings, which contains his statement:

“No book in the world deserves to be so unceasingly studied, and so profoundly meditated upon asthe Bible.”

On March 13, 1812, John Quincy Adams noted:

“This morning I finished the perusal of the German Bible.”

After negotiating the Treaty of Ghent, John Quincy Adams wrote from London, December 24, 1814:

“You ask me what Bible I take as the standard of my faith – the Hebrew, the Samaritan, the old English translation, or what? I answer, the Bible containing the Sermon on the Mount

The New Testament I have repeatedly read in the original Greek, in the Latin, in the Geneva Protestant, in Sacy’s Catholic French translations, in Luther’s German translation, in the common English Protestant, and in the Douay Catholic translations.

I take any one of them for my standard of faith.”

On December 31, 1825, John Quincy Adams wrote in his diary:

“I rise usually between five and six…I walk by the light of the moon or stars, or none, about four miles, usually returning home…I then make my fire, and read three chapters of the Bible.”

Poet Ralph Waldo Emerson wrote concerning John Quincy Adams:

“No man could read the Bible with such powerful effect, even with the cracked and winded voice of old age.”

John Quincy Adams wrote:

“I speak as a man of the world to men of the world; and I say to you, Search the Scriptures! The Bible is the book of all others…not to be read once or twice or thrice through, and then laid aside, but to be read in small portions of one or two chapters every day.”

At the age of 77, John Quincy Adams was vice-president of the American Bible Society, where he stated, February 27, 1844:

“I deem myself fortunate in having the opportunity, at a stage of a long life drawing rapidly to its close, to bear at…the capital of our National Union…my solemn testimonial of reverence and gratitude to that book of books, the Holy Bible

The Bible carries with it the history of the creation, the fall and redemption of man, and discloses to him, in the infant born at Bethlehem, the Legislator and Saviour of the world.”

Temporary electronic tattoos could soon help people fly drones with only thought and talk seemingly telepathically without speech over smartphones, researchers say.

Commanding machines using the brain is no longer the stuff of science fiction. In recent years, brain implants have enabled people to control robotics using only their minds, raising the prospect that one day patients could overcome disabilities using bionic limbs or mechanical exoskeletons.

But brain implants are invasive technologies, probably of use only to people in medical need of them. Instead, electrical engineer Todd Coleman at the University of California at San Diego is devising noninvasive means of controlling machines via the mind, techniques virtually everyone might be able to use.

His team is developing wireless flexible electronics one can apply on the forehead just like temporary tattoos to read brain activity.

“We want something we can use in the coffee shop to have fun,” Coleman says.

The devices are less than 100 microns thick, the average diameter of a human hair. They consist of circuitry embedded in a layer or rubbery polyester that allow them to stretch, bend and wrinkle. They are barely visible when placed on skin, making them easy to conceal from others.

The devices can detect electrical signals linked with brain waves, and incorporate solar cells for power and antennas that allow them to communicate wirelessly or receive energy. Other elements can be added as well, like thermal sensors to monitor skin temperature and light detectors to analyze blood oxygen levels.

Using the electronic tattoos, Coleman and his colleagues have found they can detect brain signals reflective of mental states, such as recognition of familiar images. One application they are now pursuing is monitoring premature babies to detect the onset of seizures that can lead to epilepsy or brain development problems. The devices are now being commercialized for use as consumer, digital health, medical device, and industrial and defense products by startup MC10 in Cambridge, Mass.

Stories about persecution seem to be dominating international headlines of late. On Tuesday, we told you about four Christian missionaries who were arrested in Benghazi, Libya, on charges that they were proselytizing. And now, Asia News reports that Saudi Arabian officials recently detained 53 Ethiopian Christians after they were caught holding a prayer meeting in a private home.

Among the 46 women and six men taken into custody were three faith leaders who are being accused of attempting to convert Muslims to Christianity — something that is forbidden in a country that only allows for religious practice and expression associated with the Islamic faith. The incident purportedly unfolded on Feb. 8 in Dammam, the capital of Saudi Arabia’s Eastern Province.

Planned Parenthood Botched Abortion, Left Part of Baby Inside Woman | LifeNews.com

 

Planned Parenthood Botched Abortion, Left Part of Baby Inside Woman | LifeNews.com.

by Steven Ertelt

A Planned Parenthood abortion patient has filed suit against the abortion business for botching an abortion so badly that it left part of the body of the unborn baby inside her afterwards.

Attorneys with Alliance Defending Freedom, a pro-life legal group, filed suit on behalf of a Colorado against Planned Parenthood of the Rocky Mountains and one of its doctors. The mother says the abortion facility forced her to undergo an abortion without anesthesia and then left part of her baby’s body inside of her.

The lawsuit alleges that 40-year-old Ayanna Byer changed her mind about the abortion after Planned Parenthood in Colorado Springs could not provide her with the agreed-upon intravenous anesthesia for pain, but the abortionist proceeded with the abortion anyway. ADF informed LifeNews that, once the abortion was complete, Byer was sent home but ended up in an emergency room two days later because the abortionist had botched the procedure.

“A woman’s life is more important than Planned Parenthood’s bottom line,” said Alliance Defending Freedom allied attorney Doug Romero of Denver. “What Planned Parenthood did to Ayanna is beyond the pale. They clearly put her through extraordinary cruelty and jeopardized her life. Their actions were intolerable.”

According to a statement provided by the on-call emergency room doctor who assisted Byer, she “was septic with a high fever and elevated white count. She required an immediate high-risk surgery to remove the remaining tissue that had been left during the previous procedure done at Planned Parenthood. Because of the continued pain and heavy bleeding, I was concerned that the patient might have had an ectopic pregnancy. I called Planned Parenthood the following day to inquire about pathology results to only learn that no pathology is done on abortion patients. The doctor performing the abortion ‘looks’ at the tissue and makes a diagnosis.” Read the rest:Planned Parenthood Botched Abortion, Left Part of Baby Inside Woman | LifeNews.com.
