Robots are cloning again.
Robots can evolve. Robots can reproduce. All hail our robot overlords.

For several years, Professor George Hanna from Imperial College London has been directing work toward the development of a test that can detect cancers of the esophagus and stomach by measuring the levels of five chemicals in a patient’s breath. These chemicals are butyric, pentanoic and hexanoic acids, butanal, and decanal, which previous research has identified as pointers to the presence of stomach or esophageal cancer.
In 2015, Professor Hanna announced the results of the first clinical study analyzing the breath samples of 210 patients. The patents exhaled into a breathalyzer-like device, which used a selected ion flow tube mass spectrometer to detect the presence of any of the five aforementioned chemicals in the breath sample. The 2015 study achieved a 90 percent accuracy rate in correctly identifying the two cancers, and a recently completed, broader study has also proven successful.
The new study collected samples from 335 people across four London hospitals. Around half of the group had been diagnosed with stomach or esophageal cancer and the other half had shown no evidence of cancer after having an endoscopy. After analyzing all the samples, the new breath test achieved an 85 percent accuracy rate, correctly identifying those both with and without cancer.
Looking for that perfect gift for the medical student in your life? Search no more.
Is it wise to make medical students feel like renegade fictional genius Tony Stark, magically waving human bodies apart like the holographic diagrams in the Iron Man basement lab? Should we use technology to make millennials feel like superheroes? Stop asking difficult philosophical questions and look at how cool this is.
This augmented reality app is called Project Esper. It uses hand gestures to allow the users move and study anatomy. Users can pull the human body apart and investigate the organs and limbs piece by piece. Look—just look at this magical Star Trek karate:
Someday, we will have glasses or contacts that will be able to detect tumors and notify us or even contact doctor’s office to set up the appointment for us.
Researchers have shown that they could efficiently capture and simultaneously filter out the circulating tumor cells (CTCs) permanently from cancer patients’ whole blood, which otherwise could gain access into the blood and invariably cause metastasis.

Interesting study on brain receptors.
Researchers from UZH have discovered how the perception of meaning changes in the brain under the influence of LSD. The serotonin 2A receptors are responsible for altered perception. This finding will help develop new courses of pharmacotherapy for psychiatric disorders such as depression, addictions or phobias.
Humans perceive everyday things and experiences differently and attach different meaning to pieces of music, for instance. In the case of psychiatric disorders, this perception is often altered. For patients suffering from addictions, for instance, drug stimuli are more meaningful than for people without an addiction. Or patients with phobias perceive the things or situations that scare them with exaggerated significance compared to healthy people. A heightened negative perception of the self is also characteristic of depressive patients. Just how this so-called personal relevance develops in the brain and which neuropharmacological mechanisms are behind it, however, have remained unclear.

TDP-43 Protien tied to Alzheimers according to a Mayo Clinic Study.
Since the time of Dr. Alois Alzheimer himself, two proteins (beta-amyloid (Aβ) and tau) have become tantamount to Alzheimer’s disease (AD). But a Mayo Clinic study challenges the perception that these are the only important proteins accounting for the clinical features of the devastating disease.
My doctor needs one of these.
CAE Healthcare announced the release of CAE VimedixAR, an ultrasound training simulator integrated with the Microsoft HoloLens, the world’s first self-contained holographic computer. The announcment marks CAE Healthcare as the first company to bring a commercial Microsoft HoloLens application to the medical simulation market.
VimedixAR delivers an unprecedented simulation-based training experience, allowing learners to interact and move freely within a clinical training environment that is augmented with holograms. For the first time, students will be able to examine 3D anatomy inside the body of the Vimedix manikin. As learners practice scanning an animated heart, lungs or abdomen, they will observe in real-time how the ultrasound beam cuts through anatomy to generate a ultrasound image.

Allergic diseases are making one’s life more complicated and almost all treatment is only suppressing the symptoms. Fortunately, Stephen Miller of Northwestern University and Lonnie Shea of the University of Michigan can now mask allergen particles on their way into the body. This teaches the immune system not to attack the allergens in the future.
Their latest research published in the journal PNAS finally introduces a way to actually cure allergies altogether, instead of concealing symptoms with antihistamines such as Benadryl and Claritin…

Knowing how or why genes are turned on and off during development, as well as understanding how they respond to environmental changes, will prove to be useful in our quest to find ways to prevent diseases. In addition, while the human initiator is responsible for regulating more than half of human genes, there are other sequences that control gene activity. This achievement could lead scientists to discover other sequence signals.
“The solution of the human Initiator code will enable us to explore new frontiers in gene regulation. In the future, it will be possible to use the code to identify other regulatory signals and, in this way, gain a more complete understanding of how human genes are turned on and off,” Kadonaga says.
