After a 10 year study of 3000 people, researchers have made the surprising discovery that hearts age differently in men and women.

We need personalised medicine

We know people age differently, both inside and outside. This is down to a complex interplay of genetics and environment, which leads to significant variation in the aging process for all of us. What we didn’t expect was that such a striking difference would emerge between the genders. So what does this mean? Could there be more we’re missing?

As of this month, over 4,000 Americans are on the waiting list to receive a heart transplant. With failing hearts, these patients have no other options; heart tissue, unlike other parts of the body, is unable to heal itself once it is damaged. Fortunately, recent work by a group at Carnegie Mellon could one day lead to a world in which transplants are no longer necessary to repair damaged organs.

“We’ve been able to take MRI images of coronary arteries and 3-D images of embryonic hearts and 3-D bioprint them with unprecedented resolution and quality out of very soft materials like collagens, alginates and fibrins,” said Adam Feinberg, an associate professor of Materials Science and Engineering and Biomedical Engineering at Carnegie Mellon University. Feinberg leads the Regenerative Biomaterials and Therapeutics Group, and the group’s study was published in the October 23 issue of the journal Science Advances. A demonstration of the technology can be seen below.

“As excellently demonstrated by Professor Feinberg’s work in bioprinting, our CMU researchers continue to develop novel solutions like this for problems that can have a transformational effect on society,” said Jim Garrett, Dean of Carnegie Mellon’s College of Engineering. “We should expect to see 3-D bioprinting continue to grow as an important tool for a large number of medical applications.”

Treating the brain isn’t like the rest of the body. Your blood-brain barrier shields it; filtering the blood to ensure nothing untoward makes it through. This protection is normally a good thing, but it becomes a problem if you want to deliver therapeutic drugs through it. This method could be a solution.

Smuggling therapeutics

Many diseases like Parkinson’s and Alzheimer’s disease are extremely difficult to treat. Only very specific molecules can make it through the brain’s secure barrier, and most drugs don’t make the cut. This poses a challenge when you want to treat disease inside the brain, and so efforts have been focused on finding a way to overcome this. New research has now demonstrated a way of treating Parkinson’s disease with a surgical treatment that opens up a small route to bypass the barrier; essentially a smuggling hatch into your brain.

The much pursued fountain of youth can become a reality if humans agree to share their DNA information, according to Google Ventures’ CEO Bill Maris, who has warned that “we’re all going to die” earlier if we keep our genetic codes secret.

Maris, who aims to digitize DNA, stressed during a Wall Street Journal technology conference in California that our genomes “aren’t really secret,” urging those protective of their genetic information to loosen the reins a bit.

Noting that genetic material is constantly left lying around in public, Maris addressed those who remain nervous about the digitization of DNA. “What are you worried about?” he said on Tuesday, adding that a person could easily gather information by fishing a used cup out of the trash and taking it to a lab for analysis.

The $1.7 billion investment has finally opened its doors to the public, and the robots are ready to provide patients with a medical experience that’s truly revolutionary.

Hailed as the first fully digital hospital in North America, the Humber River Hospital in Toronto, CA finally opened its doors to the public on October 18. In addition to being equipped with the most advanced technologies, robots currently man several areas of the facility. This includes the radiology area where they facilitate the X-Ray procedure and the chemotherapy area where they mix, prepare, and monitor the drugs being administered to the patients. Before the drugs get to the patients, each package is checked and scanned thoroughly through an information management system to make sure that the patients get the correct treatment. These automated robots will also be assisting the health care staff by carrying and delivering medical supplies and food for patients.

Remember that paralyzed guy from Southern California who managed to walk on his own accord thanks to a revolutionary technique that bridged the gap in his severed spinal column with a wireless Bluetooth link? A team of doctors at Ohio’s Case Western Reserve University have reportedly accomplished the same feat with a patient’s arms.

The team described its initial findings at a meeting of the Society for Neuroscience in Chicago on Tuesday. The system works much like that of the earlier team at UC Irvine: a brain-control interface (BCI) reads the patient’s brain waves emanating from his motor cortex, converts them into actionable electrical signals and wirelessly transmits them to an actuator “sewn into” the patient’s arm. This actuator is comprised of 16 filament wires that generate electrical impulses, which cause various muscle groups to contract when stimulated. The patient thinks about moving his arm and it does so — well, sorta.

As long as they don’t enter the food supply.

First micropigs, now dogs: Scientists in China have used a gene-editing technique to produce the world’s first genetically engineered pooches. Although these two endeavors share scientific roots, with their production aimed at assisting medical research, unlike the teeny tiny pigs, the researchers behind this latest project are not intending to sell their customized animals as pets.

So it probably won’t come as a surprise that the dogs weren’t engineered to be cuter, fluffier or more pocket-sized: they had their DNA tweaked to make them more muscly. The first of many potential edits the team would like to carry out, this was done with the forces in mind.

How cool is this!

Rendering of a virus used in the MIT experiments. The light-collecting centers, called chromophores, are in red, and chromophores that just absorbed a photon of light are glowing white. After the virus is modified to adjust the spacing between the chromophores, energy can jump from one set of chromophores to the next faster and more efficiently.

To whom it may concern,

Cryonics is a legitimate science-based endeavor that seeks to preserve human beings, especially the human brain, by the best technology available. Future technologies for resuscitation can be envisioned that involve molecular repair by nanomedicine, highly advanced computation, detailed control of cell growth, and tissue regeneration.

With a view toward these developments, there is a credible possibility that cryonics performed under the best conditions achievable today can preserve sufficient neurological information to permit eventual restoration of a person to full health.
