Michael Whitehouse, Staff WriterModern medicine has revolutionized the way we treat disease and illness. Each decadenew breakthroughs are made as we continue to unlock our knowledge of the human body, and how to treat its fragility. But what happens when modern medicine identifies normal human characteristics as disorders, or misdiagnoses an existing condition? The result is startling: Prescribing drugs to individuals who don’t need them, in many cases creating a downward [...]View Article Here Read More
Mae Chan, Prevent DiseaseIt’s not just the high fat, salt or sugar content of processed foods that is driving obesity and diet-related illnesses — the lack of food diversity is killing our gut flora, claims one researcher. If we exclude sugar, approximately 80 percent of all calories in processed foods come from a combination of four ingredients.Drawing upon evidence from multiple studies, Professor of genetic epidemiology at King’s College London and author of  [...]View Article Here Read More
According to our work, information isn’t lost once it enters a black hole. It doesn’t just disappear.What sort of information are we talking about? In principle, any information drawn into a black hole has an unknown future, according to modern physics. That information could include, for example, the characteristics of the object that formed the black hole to begin with, and characteristics of all matter and energy drawn inside.
In the 1970s, [Stephen] Hawking proposed that black holes were capable of radiating particles, and that the energy lost through this process would cause the black holes to shrink and eventually disappear. Hawking further concluded that the particles emitted by a black hole would provide no clues about what lay inside, meaning that any information held within a black hole would be completely lost once the entity evaporated.
Though Hawking later said he was wrong and that information could escape from black holes, the subject of whether and how it’s possible to recover information from a black hole has remained a topic of debate.
Stojkovic and Saini’s new paper helps to clarify the story.Stojkovic added:
Instead of looking only at the particles a black hole emits, the study also takes into account the subtle interactions between the particles. By doing so, the research finds that it is possible for an observer standing outside of a black hole to recover information about what lies within.
Interactions between particles can range from gravitational attraction to the exchange of mediators like photons between particles. Such “correlations” have long been known to exist, but many scientists discounted them as unimportant in the past.
These correlations were often ignored in related calculations since they were thought to be small and not capable of making a significant difference.
Our explicit calculations show that though the correlations start off very small, they grow in time and become large enough to change the outcome.

Matthew Butler, GuestPeople save up for retirement, but how well do we prepare for the journey after? Ancient cultures put great emphasis on the afterlife, because they knew consciousness continued after death. They were right: Out-of-body experiences reveal we really do exist beyond the body. Knowing this truth should inspire us to seek in life what really matters and remains after death – awakened consciousness.What is the greatest mystery of life? According to a legendar [...]View Article Here Read More
