At the cellular level, aging and cancer are two sides of the same coin. The mechanism that limits a cell’s lifespan can be slowed down, but that can turn them cancerous, as they divide unchecked.
Much mystery surrounds the physiological processes by which humans age, but scientists are learning more all the time. With this knowledge come new possibilities around how we can not only slow them down, but possibly even reverse them. A new breakthrough at the University of Colorado is the latest advance in the area, demonstrating how a chemically altered nutritional supplement may well reverse aging of the blood vessels, in turn giving cardiovascular health a vital boost.
Australian company Titomic has unveiled what it claims is the world’s largest metal 3D printer at its fully automated Melbourne facility. Utilizing a patented process co-developed with Australian federal scientific research agency the CSIRO, the 3D metal printer boasts a build area 9 m long, 3 m wide and 1.5 m high (29.5 x 9.8 x 4.9 ft), however the printing process isn’t constrained to this booth size, meaning it could be used to print even larger objects.
A new portable system small enough to mount on a personal firearm provides its user with the ability to quickly locate the source of hostile gunfire. The PEARL system, created by French defense contractor Metravib, uses acoustic sensors to determine the source of gunfire during the confusion of combat.
“Evil” GE foods and “eco-friendly” organics
Across the globe, genetically engineered (GE) crops face opposition from environmental and organic food activists, who claim the crops harm the environment and endanger human health.
How factual are their claims? The evidence strongly supports GE over organic crops.
Not long ago, Vijay visited the Sprouts organic food store in San Jose, California. To his surprise, organic vegetables that had shorter shelf-life and higher risk of bacterial contamination and thus serious illness were priced two to ten times more than their GE and conventional food alternatives. The store is famous among millennial techies in the Silicon Valley and enjoys reasonable sales. One possible explanation would be the false notion that GE foods are risky or injurious to health; another is that buyers incorrectly believe organic produce have fewer pesticides, are more nutritious or better protect the environment.
But in science, neither a belief nor even a general “consensus” determines truth. A thousand people could claim the theory of gravity is wrong, but one simple scientific proof would prove their consensus false. Similarly, the safety of genetically modified foods cannot be determined by the increasingly vitriolic voices of anti-GE groups. It requires robust scientific testing by actual experts in various fields.
The world is in desperate need of new antibiotics, as bacteria continue to evolve and develop resistance to the ones we have. Now, researchers at La Trobe University have found a peptide in the flower of a tobacco plant that could be the first of a brand new kind of antibiotic, hopefully helping us avoid the looming doomsday of superbugs.
For decades researchers have worked to find a way to orally administer insulin effectively to patients with diabetes. Now this game-changing treatment is one step closer to reality, with pharmaceutical company Oramed embarking on a final Phase 2b human clinical trial to prove the efficacy of its oral insulin before moving to the final stages of trials and registrations that could bring the treatment to market within a few short years.
“Broken nanodiamonds are forever,” or so says a team of scientists at the US Department of Energy’s (DOE) Argonne National Laboratory. By combining broken nanodiamonds with two-dimensional molybdenum disulfide layers, they’ve managed to produce a self-generating, very-low-friction dry lubricant with hundreds of applications that lasts practically forever.
The U.S. Army has taken note of the explosion of cheap, unmanned drones on the modern battlefield and is working to field a variant of the Stryker armored vehicle to shoot them down. The new variant will go to brigade combat teams fielding the Stryker vehicle, including an armored cavalry regiment in Europe.
