PI3K (phosphoinositide 3-kinase) is a cell-signaling molecule found tied to breast, ovarian, and endometrial cancers.

Important insights into the biology that underlies glycolysis, the metabolic process that enables cancer cells to generate biomass and energy, have been revealed by new research, confirming the importance of sugar to cancer survival.

With the recent use of genetically engineered mosquitoes in Brazil to halt the spread of the Zika virus, we might be beginning to see some major health improvements as a consequence of the genetics revolution. A world in which mosquitoes were all but eliminated from the ecosystem would look quite different from the world of today, especially for people living in the tropics where the threat of mosquito transmitted infections does more than just mar an otherwise tranquil margarita sipped from the veranda of a beach resort. This is not to beggar the more mundane advantages of a mosquito-free habitat, but rather call attention to the fact that for large parts of the world, including Brazil, mosquitoes can be the difference between life and death.

Ironically, the genetic changes made to the Aedes aegypti mosquito in order to halt the spread of the Zika virus are deceptively simple. The company behind the project, Oxitec, used a modified version of something called the “Sterile Insect Technique” to create their hybrid specimens. The end goal of this process is to produce a male mosquito possessing a “self-limiting gene.” When these males mate with wild female mosquitoes, they create non viable offspring that perish soon after the birth. The end result is a rapid drop in the mosquito population of a given area.

When compared with some of the more hazardous forms of mosquito control currently in use such as massive spraying of DEET and chemical infusers popular throughout Asia, sterilizing mosquitoes sounds like an imminently reasonable approach. As a journalist who once saw his roadside samosa blasted by a massive spray of DEET from an oncoming municipal vehicle in India, I can personally attest to a preference for a genetic solution.

This is not good especially as we look at those aspirations for more nanobots to connect us to the cloud plus Mr. Kurzweil’s desire to live forever.

Medical device manufacturers are struggling to safeguard their newly connected designs from current and emerging security threats.

Could the FDA crush IoT opportunities in Healthcare?

The U.S. Food and Drug Administration last week took a step toward addressing the threat the Internet of Things poses to patients and their data by releasing some proposed guidelines for managing cybersecurity in medical devices.

“A growing number of medical devices are designed to be networked to facilitate patient care. Networked medical devices, like other networked computer systems, incorporate software that may be vulnerable to cybersecurity threats,” the FDA says in its proposal.

An experiment by University of Washington researchers is setting the stage for advances in mind reading technology. Using brain implants and sophisticated software, researchers can now predict what their subjects are seeing with startling speed and accuracy.

The ability to view a two-dimensional image on a page or computer screen, and then transform that image into something our minds can immediately recognize, is a neurological process that remains mysterious to scientists. To learn more about how our brains perform this task—and to see if computers can collect and predict what a person is seeing in real time—a research team led by University of Washington neuroscientist Rajesh Rao and neurosurgeon Jeff Ojermann demonstrated that it’s possible to decode human brain signals at nearly the speed of perception. The details of their work can be found in a new paper in PLOS Computational Biology.

The team sought the assistance of seven patients undergoing treatment for epilepsy. Medications weren’t helping alleviate their seizures, so these patients were given temporary brain implants, and electrodes were used to pinpoint the focal points of their seizures. The UW researchers saw this as an opportunity to perform their experiment. “They were going to get the electrodes no matter what,” noted Ojermann in a UW NewsBeat article. “We were just giving them additional tasks to do during their hospital stay while they are otherwise just waiting around.”

Researchers have successfully demonstrated how it is possible to interface graphene — a two-dimensional form of carbon — with neurons, or nerve cells, while maintaining the integrity of these vital cells. The work may be used to build graphene-based electrodes that can safely be implanted in the brain, offering promise for the restoration of sensory functions for amputee or paralysed patients, or for individuals with motor disorders such as epilepsy or Parkinson’s disease.

The burgeoning field of nanotechnology promises an indefinite range of capabilities in medicine, optics, communications, and other facets of applied science and engineering. On that front, the U.S. Defense Advanced Research Projects Agency’s (DARPA) Atoms 2 Products program (A2P) is funding 10 companies, universities, and institutions to develop mass-manufacturing techniques and technologies for functional products made up of nanoscale constituents. The project demonstrates a mere slice of the contributions in the mass movement to make nanotechnology a part of our everyday lives.

The following gallery highlights the work of five DARPA-funded projects in the program. The slides describe an atomic calligraphy technique for 2D atomic printing, a manufacturing method for producing high-frequency “Nanolitz” wires, the construction of pop-up sensors for laparoscopy, and a conjunct effort to use micro-robotics to build the assemblers of nanodevices.

59% of the providers surveyed recently state that they have no intentions of offering precision treatment such as CRISPR for the next 5 yrs. which means patients with MS, Dystonia, Cancer, etc. will not necessarily get proper choice of treatments that they deserve.

As the Obama administration looks to Congress to fund its $215 million Precision Medicine Initiative, a new poll of healthcare executives indicates that most hospitals and health systems are not planning on leveraging such advances in genomics and data analytics to personalize patient care.

In the poll, conducted by analytics vendor Health Catalyst, 59 percent of respondents indicated that precision medicine will not play a significant role in their organizations over the next five years.

Over the last 12,000 years or so, human civilization has noticeably reshaped the Earth’s surface. But changes on our own planet will likely pale in comparison when humans settle on other celestial bodies. While many of the changes on Earth over the centuries have been related to food production, by way of agriculture, changes on other worlds will result, not only from the need for on-site production of food, but also for all other consumables, including air.

As vital as synthetic biology will be to the early piloted missions to Mars and voyages of exploration, it will become indispensable to establish a long-term human presence off-Earth, namely colonization. That’s because we’ve evolved over billions of years to thrive specifically in the environments provides by our home planet.

Our physiology is well-suited to Earth’s gravity and its oxygen-rich atmosphere. We also depend on Earth’s magnetic field to shield us from intense space radiation in the form of charged particles. In comparison, Mars currently has no magnetic field to trap particle radiation and an atmosphere that is so thin that any shielding against other types of space radiation is negligible compared with the protection that Earth’s atmosphere affords. At the Martian surface, atmospheric pressure never gets above 7 millibars. That’s like Earth at an altitude of about 27,000 m (89,000 ft), which is almost the edge of space. And it’s not like the moon is a better option for us since it has no atmosphere at all.
