Scientists developed a strain of Salmonella that fights aggressive brain cancers which produced a remarkable 20% rate of tumor remission in a rat model, where there are normally no survivors. The bacteria were genetically equipped with a sophisticated tumor-homing mechanism along with cancer fighting weapons, causing the tumors to effectively self-destruct.

Human beings exhibit a unique trait of hand preference within the animal kingdom, the benefits and causes of which are still mostly unknown after decades of research. It turns out that such a seemingly trivial characteristic is actually governed by an incredibly complex interaction of evolutionary and environmental factors that might not give us a straightforward answer anytime soon.
Researchers claim they have debunked a long-standing misconception of the mathematical model of human mortality that predicts a set limit on aging. Their discovery comes as good news in a time of increasing breakthroughs in anti-aging therapy.
Extensive observational studies, surveys and meta-analysis moved scientists a step closer to understanding how highly-educated people can still contradict scientific facts. The result is a refined guide to effectively addressing skeptics, and it´s not based on presenting evidence, but rather identifying their underlaying motivation.
Scientists have discovered a way to activate dormant predatory centers in mice using optogenetics, causing them to go rogue and revert to hunter-associated behavior. This was achieved with stimulation of a specific pair of neurons in the brain, providing a glimpse of how the predatory behavior could have evolved over millions of years.
An international collaboration of scientists successfully produced a stable artificial strain of bacteria with an extended “genetic alphabet”. The microbe encompasses two additional “X” and “Y” nucleotides, which enable it to store increased information within its genome, laying foundations for new forms of life.
USDA approved the sale of genetically modified (GM) apples that “stay fresh” up to three weeks after being sliced or bruised, which are expected to enter stores by March. This comes as an answer addressing the major problem of wasting apples, with nearly 40% of them being discarded due to superficial bruising and browning.
Developer of NGS devices Ilumina claims its new NovaSeq instrument will soon manage to sequence a person´s entire genome for less then $100 in as little as 60 minutes. This would represent a marginal improvement from the current benchmark, which stands at roughly $1,000.
Researchers from Johns Hopkins University successfully modified mosquitoes to render them highly resistant to dengue virus – a disease responsible for nearly 25,000 deaths each year. Their breakthrough could lead to even more resistant mosquitoes in the future, potentially ending the war on mosquito-transmitted diseases.
The World Health Organization (WHO) confirmed that a new experimental vaccine proved 100% effective against Ebola based on preliminary results. In a large study the organization conducted in Guinea, where Ebola is still at large, not a single vaccinated individual developed the disease.
