Are We Real or Holograms?, Fortified Seasonings Fight Nutrient Deficiencies, Send Cancer Cells into Space for Radiation Study, Does Marijuana Use Reduce Domestic Violence?
Are We All Real or Are We Just Holograms?
Most, if not all of us, think of ourselves as real, living and breathing people, actual 3D physical objects. But according to quantum physics, all of us and our entire world and universe could, in reality, just be a simple 2D hologram, a kind of optical illusion.
The U.S. Department of Energy’s Fermi National Accelerator Laboratory wants to find out if we’re really holograms, as well as seek out answers to other perplexing mysteries of the universe, so they’ve cranked on their Holometer – a sophisticated piece of equipment that studies the “quantum character of space” – and have begun gathering necessary data for study and experimentation.
Fortifying Condiments and Seasonings Could Reduce Micronutrient Deficiencies Say Scientists
Scientists at the University of Illinois are working on a unique approach they think will help treat micronutrient deficiencies found to be widespread in some countries.
The Illinois researchers are looking at ways to fortify various condiments and seasonings with micronutrients as part of an effort by the World Health Organization (WHO) to fight these deficiencies.
The researchers said that the health and cognitive development of at least 33% of the world’s population suffer from micronutrient deficiencies. They also found that since most of the people in the affected areas regularly use condiments, such as soy sauce or other seasonings, fortifying them could provide a great way to correct these nutritional deficiencies.
ESA Trainee Wants to Send Cancer Samples into Space
There are a number of scientists and even lay people who would like to send humans on missions to Mars or further into deep space. Both are goals that have been talked about for a long time and lately have been getting plenty of attention from governmental space agencies and even some private companies.
But while the science and technology needed to accomplish these bold missions are being developed, there are still a number of serious issues that must first be addressed before spacecraft are launched to a destination so far away.
Among the biggest challenges facing scientists researching deep space missions is the problem of protecting the space travelers from incredibly high doses of radiation, not only from the sun but also from cosmic rays that originate in the far reaches of space.
To better understand how radiation particles can affect human DNA and trigger cancer, Yassen Abbas, a graduate trainee with the European Space Agency’s Life, Physical Science and Life Support Laboratory is proposing a mission that would send samples of osteosarcoma cells, a type of bone cancer, into space beyond the protection of Earth’s atmosphere and magnetosphere.
Cameras and related equipment onboard a spacecraft that carry the cells would be used to study how the cells are damaged by the radiation and how any genetic damage can be repaired in real time.
Study: Marijuana Use among Couples May Reduce Incidents of Domestic Violence
Could the smoking of marijuana help reduce domestic violence? That just might be the case, according to some new findings from research conducted by scientists at the University Of Buffalo School Of Public Health and Health Professions and the Research Institute on Addition.
The researchers studied 634 couples over the course of the first nine years of marriage and found that the more often they smoked marijuana, the less likely they were to become involved incidents of domestic violence.
The researchers said that that further research into the link of marijuana use and the likelihood of domestic violence is needed before any stronger conclusions could be made.
Sounding like a miniature jackhammer in overdrive, a quiet morning’s peace is suddenly interrupted by bursts of loud, rapid tapping. It doesn’t take long, however, to realize that the intense and precise tapping is actually the sound of a woodpecker using his beak to search for his breakfast – usually insects or tree sap – in a neighboring tree.
Some ornithologists (scientists who study birds) estimate that a woodpecker can peck at a tree at speeds of up to 20 pecks per second or 1,200 per minute. Scientists say that a woodpecker’s brain is able to withstand g-forces of 1,200 G’s from the repeated impacts and deceleration brought on by this rapid pecking.
That’s a lot of physical stress for any living creature to bear. Yet, for woodpeckers, it’s a necessity for survival.
Did you ever wonder how these hardy little birds are able to endure this seemingly punishing routine day after day without injuring themselves?
Chinese scientists thought studying how a woodpecker can regularly tolerate such severe physical impact may also provide some insight into what it would take to protect our bodies from harm that’s caused by shock and vibrations due to high-velocity impacts, such as an automobile accident.
The research team, led by Wu Chengwei at the Dalian University of Technology in northeastern China, decided that the best way to learn how a woodpecker’s body can function as an anti-shock structure was to build a cutting-edge, high-precision 3D model of the bird.
First data from extensive CT scans of a woodpecker’s body were fed into a computer that had been programed with specialized software to create their unique and detailed models.
Tests conducted with the computer models revealed that the creature’s body not only helps support it as it pecks on a tree, it also absorbs and stores most (99.7%) of the energy generated by the repeated impacts in the form of strain energy. The amount of remaining impact energy (.3%) that actually enters the brain is significantly reduced.
The researchers also said that various features in the bird’s head, such as its beak, skull, and hyoid bone (a special bone that’s supported by muscles instead of other bones) further reduce most of the remaining the strain energy that may be absorbed by the brain.
Whatever small amount of impact energy that remains and enters the brain is gradually transformed into heat, said the researchers. This heat caused by the remaining impact energy causes the bird’s brain temperature to quickly rise, which is why woodpeckers peck at the tree in one rapid burst, pause momentarily and resume with another burst of pecking.
