Could reincarnation be memories passed through generations in our DNA?

New research has shown that it may be possible for information to be inherited biologically through chemical changes that occur in our DNA, possibly explaining “past memories” or reincarnation claims reported by some people. During the tests, researchers demonstrated that mice can pass on learned information about traumatic or stressful experiences, in this case avoiding the smell of cherry blossom, to subsequent generations.

New “sound wave” knife is so accurate, surgeons can detach a single cancer cell with it

Scientists at the University of Michigan have developed a new knife that uses high-amplitude sound waves, instead of a knife blade, to cut tissue. The new sound-based knife, which can focus sound waves to finer points than every before, is magnitudes more accurate than previous technologies. It can cut an area of tissue, using pressure rather than heat, that measures as little as 75 by 400 micrometer allowing researchers to remove a single ovarian cancer cell and cut a 150 micrometer hole through the middle of an artificial kidney stone. In fact, the beam is so finely focused, painless surgery may be possible by simply avoiding nerve fibers. Researchers who developed the new therapeutic ultrasound approach say it could lead to an invisible knife for noninvasive surgery.

DARPA expanding foam used to stop internal bleeding

DARPA funded researchers have developed a new type of expandable foam that can stop internal bleeding long enough to get the soldier off the battlefield and into surgery. The foam chemical is injected into the chest as two separate chemicals. When the chemicals come into contact with each other, they expand, molding itself around internal organs and filling the chest cavity before hardening and sealing off any hemorrhages. Pre-clinical trials in pigs showed an 8% survival rate using existing compression care techniques and a 72% survival rate using the newly developed foam.

New contact lens technology allows for heads-up display (HUD) for wearers

According to the Telegraph, Ghent University's center of microsystems technology has developed a spherical curved LCD display which can be embedded in contact lenses and handle projected images using wireless technology. The technology allows the entire surface of the contact lens to be used for the display giving the wearer a true heads-up display (HUD).

New ultra-small carbon-fiber electrode material allows for better connections in the human brain

When it comes to implanting material in the brain, smaller is better as small contaminants are essentially “ignored” by the body’s immune system. As such, researchers have developed a new “stealthy neural interface” made from a single carbon fiber thread only 7 micrometers wide and coated with chemicals to make it resistant to proteins in the human brain. This new microthread material is designed to pick up signals from a single neuron as it fires and is 100 times smaller than the material currently used in animal brains.

New injectable, gas-filled microparticles allow person to breathe for up to 30 minutes without, ehhh, breathing

Researchers have developed tiny, gas-filled microparticles that can be injected directly into the blood system to quickly oxygenate blood providing vital oxygen to the patient for up to 30 minutes per injection. The microparticles are made from a single layer of fatty molecules (lipids) that encapsulate a tiny pocket of oxygen gas (about 3-4 times the content of our own red blood cells). Injection of the microparticles, which are so small, they can pass through capillaries where free gas would get stuck, restore oxygen levels in the person within seconds and keep the person alive for up to 30 minutes without taking a breath. The microparticles are not simply carriers for oxygen – they are designed to oxygenate the person’s body even if the lungs are not functioning properly.

New wearable personal firewall developed for implanted medical devices – protects insulin pumps and pacemakers from hijacking attacks

News that personal medical devices such as insulin pumps, pacemakers, and other wearable or implanted devices, could be hacked sent shockwaves through the medical community but researchers from Purdue and Princeton were quick to react. They have developed a signal-jamming personal firewall to protect medical devices, such as insulin pumps and pacemakers, from being hacked.

Just in time for Halloween – researchers fill dog with zombie juice then bring the dead dog back to life

Scientists at the University of Pittsburgh’s Safar Center for Resuscitation Research have made good their name. Researchers took 24 dogs and stopped their hearts and waited until there was no brain activity. They then drained the dogs’ blood and replaced it with a chilled saline solution (zombie juice). Then with one foot outside the door, they restarted the dogs’ hearts.

Girl has stomach removed after drinking cocktail with liquid nitrogen in it

Liquid nitrogen boils at -196C, a characteristic that makes it pretty cool for oh, flash freezing alcoholic beverages and making cocktails give off a cloud of smoky vapor. That’s what Oscar’s Wine Bar in the United Kingdom puts in their drinks to give them that “cool” look. Until yesterday when Gaby Scanion, a teenager who was drinking at the bar with her friends, had to be rushed to the hospital with severe stomach pain.
