Stealth DNA-based carbon nanotubes tunnel into cells to deliver targeted drugs
A team led by the Lawrence Livermore scientists has created a new way to selectively deliver drugs to a specific area in the body using carbon nanotubes (CNTs).
(KurzweilAI reported on October 17 a similar attempt to sneak drugs into cells using a DNA-based drug-delivery system: nanoscale “cocoons” made of DNA target cancer cells, tricking the cells into absorbing the cocoon, which then unleashes anticancer drugs.)
“Many good and efficient drugs that treat diseases of one organ are quite toxic to another,” said Aleksandr Noy, an LLNL biophysicist who led the study and is the senior author on the paper appearing in the Oct. 30 issue of the journal Nature. “This is why delivery to a particular part of the body and only releasing it there is much better.”
The DNA-based carbon nanotubes, dubbed “porins,” tunnel through cell membranes. They simulate ion channels, which are used by cells to transport vital chemicals: the short CNTs form tiny pores that transport water, protons, small ions, and DNA.
Porins have significant implications for future health care and bioengineering applications, according to the researchers. In addition to delivering drugs to the body, they could serve as a foundation of novel biosensors and DNA sequencing applications, and be used as components of synthetic cells.*
“We found that these nanopores are a promising biomimetic platform for developing cell interfaces, studying transport in biological channels, and creating biosensors,” Noy said. “We are thinking about CNT porins as a first truly versatile synthetic nanopore that can create a range of applications in biology and materials science.”
The team included colleagues at the Molecular Foundry at the Lawrence Berkeley National Laboratory, University of California Merced and Berkeley campuses, and University of Basque Country in Spain.
* The research showed that CNT porins display many characteristic behaviors of natural ion channels: they spontaneously insert into the membranes, switch between metastable conductance states, and display characteristic macromolecule-induced blockades. The team also found that, as in the biological channels, local channel and membrane charges could control the ionic conductance and ion selectivity of the CNT porins.
Abstract of Stochastic transport through carbon nanotubes in lipid bilayers and live cell membranes
There is much interest in developing synthetic analogues of biological membrane channels1 with high efficiency and exquisite selectivity for transporting ions and molecules. Bottom-up2 and top-down3 methods can produce nanopores of a size comparable to that of endogenous protein channels, but replicating their affinity and transport properties remains challenging. In principle, carbon nanotubes (CNTs) should be an ideal membrane channel platform: they exhibit excellent transport properties4, 5, 6, 7, 8 and their narrow hydrophobic inner pores mimic structural motifs typical of biological channels1. Moreover, simulations predict that CNTs with a length comparable to the thickness of a lipid bilayer membrane can self-insert into the membrane9, 10. Functionalized CNTs have indeed been found to penetrate lipid membranes and cell walls11, 12, and short tubes have been forced into membranes to create sensors13, yet membrane transport applications of short CNTs remain underexplored. Here we show that short CNTs spontaneously insert into lipid bilayers and live cell membranes to form channels that exhibit a unitary conductance of 70–100 picosiemens under physiological conditions. Despite their structural simplicity, these ‘CNT porins’ transport water, protons, small ions and DNA, stochastically switch between metastable conductance substates, and display characteristic macromolecule-induced ionic current blockades. We also show that local channel and membrane charges can control the conductance and ion selectivity of the CNT porins, thereby establishing these nanopores as a promising biomimetic platform for developing cell interfaces, studying transport in biological channels, and creating stochastic sensors.
Oldest DNA Ever Found Sheds Light on Humans’ Global Trek
Scientists claim to have unraveled the oldest DNA ever retrieved from a Homo sapiens bone, a feat that sheds light on modern humans’ colonization of the planet.
A femur found by chance on the banks of a west Siberian river in 2008 is that of a man who died around 45,000 years ago, they said.
Teased out of collagen in the ancient bone, the genome contains traces from Neanderthals — a cousin species who lived in Eurasia alongside H. sapiens before mysteriously disappearing.
Previous research has found that Neanderthals and H. sapiens interbred, leaving a tiny Neanderthal imprint of just about two percent in humans today, except for Africans.
The discovery has a bearing on the so-called “Out of Africa” scenario: the theory that H. sapiens evolved in East Africa around 200,000 years ago and then ventured out of the continent.
Dating when Neanderthals and H. sapiens interbred would also indicate when H. sapiens embarked on a key phase of this trek — the push out of Eurasia and into South and later Southeast Asia.
The new study, published in the journal Nature, was headed by Svante Paabo, a renowned geneticist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, who has pioneered research into Neanderthals.
– Neanderthal interbreeding –
The bone found at the Irtyush River, near the settlement of Ust’-Ishim, carries slightly more Neanderthal DNA than non-Africans today, the team found.
But it takes the form of relatively long strips, whereas Neanderthal DNA in our genome today has been cut up and dispersed in tiny sections as a result of generations of reproduction.
These differences provide a clue for a “molecular calendar”, or dating DNA according to mutations over thousands of years.
Using this method, Paabo’s team estimate interbreeding between Neanderthals and H. sapiens occurred 7,000 to 13,000 years before the Siberian individual lived — thus no more than 60,000 years ago.
This provides a rough date for estimating when H. sapiens headed into South Asia, Chris Stringer, a professor at Britain’s Natural History Museum, said in a comment on the study.
If today’s Australasians have Neanderthal DNA, it is because their forebears crossed through Neanderthal territory and mingled with the locals.
“The ancestors of Australasians, with their similar input of Neanderthal DNA to Eurasians, must have been part of a late, rather than early, dispersal through Neanderthal territory,” Stringer said in a press release.
“While it is still possible that modern humans did traverse southern Asia before 60,000 years ago, those groups could not have made a significant contribution to the surviving modern populations outside of Africa, which contain evidence of interbreeding with Neanderthals.”
Anthropologists suggest a northern branch of Eurasians crossed to modern-day Alaska more than 15,000 years ago via an “ice bridge” that connected islands in the Bering Strait, thus enabling H. sapiens to colonise the Americas.
Voiceprints Being Harvested by the Millions
Over the telephone, in jail and online, a new digital bounty is being harvested: the human voice.
Businesses and governments around the world increasingly are turning to voice biometrics, or voiceprints, to pay pensions, collect taxes, track criminals and replace passwords.
“We sometimes call it the invisible biometric,” said Mike Goldgof, an executive at Madrid-based AGNITiO, one of about 10 leading companies in the field.
Those companies have helped enter more than 65 million voiceprints into corporate and government databases, according to Associated Press interviews with dozens of industry representatives and records requests in the United States, Europe and elsewhere.
“There’s a misconception that the technology we have today is only in the domain of the intelligence services, or the domain of ‘Star Trek,'” said Paul Burmester, of London-based ValidSoft, a voice biometric vendor. “The technology is here today, well-proven and commonly available.”
And in high demand.
Dan Miller, an analyst with Opus Research in San Francisco, estimates that the industry’s revenue will roughly double from just under $400 million last year to between $730 million and $900 million next year.
Barclays PLC recently experimented with voiceprinting as an identification for its wealthiest clients. It was so successful that Barclays is rolling it out to the rest of its 12 million retail banking customers.
“The general feeling is that voice biometrics will be the de facto standard in the next two or three years,” said Iain Hanlon, a Barclays executive.
Vendors say the timbre of a person’s voice is unique in a way similar to the loops and whorls at the tips of someone’s fingers.
Their technology measures the characteristics of a person’s speech as air is expelled from the lungs, across the vocal folds of the larynx, up the pharynx, over the tongue, and out through the lips, nose, and teeth. Typical speaker recognition software compares those characteristics with data held on a server. If two voiceprints are similar enough, the system declares them a match.
The Vanguard Group Inc., a Pennsylvania-based mutual fund manager, is among the technology’s many financial users. Tens of thousands of customers log in to their accounts by speaking the phrase: “At Vanguard, my voice is my password” into the phone.
“We’ve done a lot of testing, and looked at siblings, even twins,” said executive John Buhl, whose voice was a bit hoarse during a telephone interview. “Even people with colds, like I have today, we looked at that.”
The single largest implementation identified by the AP is in Turkey, where mobile phone company Turkcell has taken the voice biometric data of some 10 million customers using technology provided by market leader Nuance Communications Inc. But government agencies are catching up.
In the U.S., law enforcement officials use the technology to monitor inmates and track offenders who have been paroled.
In New Zealand, the Internal Revenue Department celebrated its 1 millionth voiceprint, leading the revenue minister to boast that his country had “the highest level of voice biometric enrollments per capita in the world.”
In South Africa, roughly 7 million voiceprints have been collected by the country’s Social Security Agency, in part to verify that those claiming pensions are still alive.
Activists worry that the popularity of voiceprinting has a downside.
“It’s more mass surveillance,” said Sadhbh McCarthy, an Irish privacy researcher. “The next thing you know, that will be given to border guards, and you’ll need to speak into a microphone when you get back from vacation.”
Geneticists are Spell-Bound By Discovery of DNA That Confirms Fallen Angels Mated With Humans!
The World Genographic Project has been testing haplogroups (a group which relates to our deep ancestry) and has recently discovered that during the time of Noah’s flood a small group of extremely unusual DNA was introduced into the population. Geneticists have named it, Haplogroup I1.
I believe this could be the DNA proof that fallen angels had sex with humans spoken of in the book of Genesis 6:4, “The Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of men, and they bore children to them. Those were the mighty men who were of old, men of renown..”
The haplogroup I1 gene has unique characteristics unlike any other gene, and geneticists are baffled by it.
According to Paranormics.com some of the anomalies found in human hybrids with this strain of alien DNA include: toleration of extreme climates, exceptional strength and height, atheists mentality with no belief in God, intelligent, 100% literacy rate, great memory, speaks many languages, and limited sun exposure. This is a sign that this is likely Nephilim in nature, because they are known to hate God and have a giant stature in ancient times.
But this gene anomaly isn’t the only DNA proof that exists! In the desert peninsula of Paracas, located within the Pisco Province in the Ica Region on the south coast of Peru; Peruvian archaeologist, Julio Tello, discovered an enormous graveyard that housed tombs packed full of beings with the elongated skulls. Today these skulls are known as the Parcas Skulls. Not only do they date back during the time of the flood on Noah, but they have also been found with “alien DNA”…..
According to the news article in Ancient Origins:
“It is well-known that most cases of skull elongation are the result of cranial deformation, head flattening, or head binding, in which the skull is intentionally deformed by applying force over a long period of time. It is usually achieved by binding the head between two pieces of wood, or binding in cloth. However, while cranial deformation changes the shape of the skull, it does not alter its volume, weight, or other features that are characteristic of a regular human skull.
However, they say that these ‘Paracas Skulls’ are different! The cranial volume is up to 25 percent larger and 60 percent heavier than ordinary human skulls. This confirms they could not have possibly been deliberately disfigured through head binding or flattening. Not to mention, these skulls also accommodate one parietal plate instead of two.”
With the two of these DNA findings put together we have the evidence we need for the Nephilim spoken of in the Bible. Both of these findings reveal unique DNA unlike any human DNA, and the only answer is that they must be what the bible refers to as the Nephilim race.
