Memory is never a precise duplicate of the original… it is a continuing act of creation. Dream images are the product of that creation. They are formed by pattern recognition between some current emotionally valued experience matching the condensed representation of similarly toned memories.
A group of researchers at Japan’s Osaka University has developed an alternative type of plastic which is not only biodegradable in seawater but is also water-resistant under normal use. The plastic is made from cellulose nanofibers and starch, both of which were extracted from plants.
The Futurecraft.Loop project ushered in a running shoe that has been designed from scratch to be recycled. Adidas’ thinking is not to take pre-existing products and make them more sustainable, but rather to create sustainable products from square one.
The New York Times visualized the damaging, tiny particles that wreak havoc on human health. From the Bay Area to New Delhi, see how the world’s worst pollution compares with your local air. The particles are too small for the eye to see but in high concentrations, they cast a haze in the sky.
Commercial airlines often prioritize boarding for passengers traveling with small children, or for those who need extra assistance, before starting to board the faster passengers. It’s counter-intuitive, but it turns out that letting slower passengers board first actually results in a more efficient process.
Researchers have recovered evidence of ancient viruses in the glacier ice, including 28 viral groups that are new to science. As our planet undergoes climate change, these frozen records can inform predictions about which microorganisms will survive, and what the resulting environment will look like.
With more than 9 billion gigabytes of information traveling the internet every day, researchers are constantly looking for new ways to compress data into smaller packages. Cutting-edge techniques focus on lossy approaches, which achieve compression by intentionally “losing” information from a transmission.
It looks like grownups can disregard the fear-mongering about the ill effects of digital media on kids. A 2017 study in Child Development found “little or no support for harmful links between digital screen use and young people’s psychological well-being.”
Serapium Forest is the most prosperous of Egypt’s 36 tracts of land that make up an ambitious program to combat desertification by creating sustainably managed commercial forests fed entirely by wastewater.
A research team at Columbia University has made an exciting discovery, finding that a compound currently under development for a rare kidney stone disease can starve pancreatic cancer cells of a key amino acid they depend on, a technique that proved to stop tumor growth in mice.
Edward Makuka Nkoloso of Zambia had dreams to land Zambians on moon and mars beating the US and USSR in the Space race. He did everything he could with his limited resources to make his dream a reality but could he fulfill his dreams?
For science, profit, and pride, China, the U.S., and private companies are hunting for resources on the lunar surface. It’s not difficult to imagine moon development, like all development, proceeding less than peacefully, and less than equitably.
The emotional devastation of losing a loved one can certainly feel like physical pain. But can you really die from a broken heart? As it turns out, you can, from “broken-heart syndrome,” also known as stress-induced cardiomyopathy.
For decades, Nevada’s Area 51 Air Force facility has represented the eye of a conspiratorial hurricane that swirls around “evidence” that aliens exist and are hiding behind its walls. Books, TV shows, and even massive online “raids” have tried to glimpse beyond its stark signs warning against trespassers.
A conveyor belt of ocean water that loops the planet and regulates global temperatures could be heading for a tipping point. Arctic sea ice this summer was the second-lowest on record, and ocean changes in the Arctic could dramatically change the climate for much of the rest of the planet.
Food futurists and industry leaders say these high-tech vertical farming operations are the future of agriculture. Indoor-grown produce is available in more than 20 supermarket chains nationwide. But despite massive investment, questions remain about efficiency and costs.
Essential tremor is the first condition the Food and Drug Administration has approved for noninvasive surgery with focused ultrasound. It might help people with Parkinson’s, brain cancer, and even ALS.
Botox is derived from a toxin purified from Clostridium botulinum, a bacterium that thrives and multiplies in faultily canned food. The botulinum toxin is so powerful that a tiny amount can suffocate a person by paralyzing the muscles used for breathing. That’s part of what protects Allergan’s $2.8 billion Botox empire.
Fake publications are corrupting the world of research—and influencing real news. At the most benign level of the junk industry are papers, published in journals with no effective screening process, that are obvious nonsense.
Incredible feats of genetic engineering and frozen biobanks could prevent Australia’s iconic marsupials from disappearing for good. If that sounds far-fetched, it isn’t. In fact, it’s already happening.
This is the pursuit of a much longer, healthier life span using science and genetics to achieve it. Who hasn’t dreamed of staying young but how far will you be prepared to go to achieve that dream? BBC’s Gabriela Torres meets the self-experimenters and scientists who are trying to dramatically extend our lives.
A team of scientists at MIT is building devices meant to monitor people’s sleep and influence their dreams. One device, called Dormio, is an “interactive social robot” designed to detect when the user is falling asleep and affect their dreams with audio cues.
Albert Einstein’s theory of general relativity is more than a hundred years old, but still it gives physicists headaches. Not only are Einstein’s equations hideously difficult to solve, they also clash with physicists’ other most-cherished achievement, quantum theory.
Air conditioning systems can replace the entire air volume in an office building five or 10 times an hour. Machines that capture carbon dioxide from the atmosphere—a developing fix for climate change—also depend on moving large volumes of air. So why not save energy by tacking the carbon capture machine onto the air conditioner?
The fruits and vegetables we know and love are a lot more complicated than you’d think. They didn’t always look like they do. In fact, it took decades of human intervention to transform them into the delicious, nutrient-rich morsels they are today.
With more board configurations than there are atoms in the universe, the ancient Chinese game of Go has long been considered a grand challenge for artificial intelligence. On March 9, 2016, the worlds of Go and artificial intelligence collided in South Korea for an extraordinary best-of-five-game competition, coined The DeepMind Challenge Match.
It was something Tom Pollak had heard whispers about—an odd factoid, referred to now and again, usually with bewilderment: No person who was born blind has ever been diagnosed with schizophrenia. Over the past 60-some years, scientists around the world have been writing about this mystery.
The way you cope or handle things in life has a direct impact on how much anxiety you experience – tweak the way you’re coping, therefore, and you can lower your anxiety levels. Research shows that if it’s left untreated, anxiety can lead to depression, early death and suicide.
A common explanation is that because we normally hear our own voice while talking, we receive both sound transferred to our ears externally by air conduction and sound transferred internally through our bones. This bone conduction of sound delivers rich low frequencies that are not included in air-conducted vocal sound.
Air pollution may be damaging every organ and virtually every cell in the human body, according to a comprehensive new global review. The research shows head-to-toe harm, from heart and lung disease to diabetes and dementia, and from liver problems and bladder cancer to brittle bones and damaged skin.
HB11 Energy is a spin-out company that originated at the University of New South Wales, and it announced today a swag of patents through Japan, China and the USA protecting its unique approach to fusion energy generation. Fusion, of course, is the long-awaited clean, safe theoretical solution to humanity’s energy needs.
Stem cells have taken on a mythic promise in the eyes of many who are ailing and desperate. But a new crop of treatments might be nothing more than costly placebos—or possibly dangerous.
Jachymov, a small uranium mining town in the northwest of the Czech Republic, has been key in the field of radioactivity research. More than a century ago, Marie and Pierre Curie based their revolutionary work on radioactivity on material brought from there.
In just the past five years, the meaning of the human face has quietly but seismically shifted. That’s because researchers at Facebook, Google, and other institutions have nearly perfected techniques for automated facial recognition.
