Researchers have discovered a new species of banana christened “nanensis”, belonging to the Musa genus, sharing a place in the family Musaceae with more than 70 other species of bananas and plantains. It’s scientific name honors the province of Nan where the type specimens were collected.
Prosthetics has come a long way from its humble beginnings – the crude wooden legs of yore are a far cry from the technological marvels we can create to replace our limbs today. However, there is one thing that, with all our know-how, we haven’t yet been able to incorporate in them: a sense of touch. A research team from Stanford University aims to fix this shortcoming, and has developed technology that can “feel” when force is exerted upon it, then transmit the sensory data to brain cells – in essence, they’ve created an artificial skin.
Recent fossils unearthed in the Chinese province of Daoxian come to unravel the story of humanity’s spread as we know it today. The find consists of 47 teeth, belonging to modern humans, but what’s really important is their age – they have been dated to 80,000 years ago. This number doesn’t fit with the “Out of Africa” migration theory, holding that humans originate and have spread from the horn of the continent all around the world. The theory as we know it can’t explain human presence in the area for another 20,000 years.
It’s easy to assume that with economic gain comes happiness — we live in capitalism, after all. But science comes to prove us all wrong yet again, and shows that the link between economics and happiness is much more complicated that we thought. Money can’t buy happiness, it seems.
Chinese researchers discovered a chemical compound that works just as well as morphine — without any of the negative side effects. The substance is derived from the venom of a centipede native to China. The discovery has huge medical applications, and could potentially reduce the country’s military reliance on morphine for battlefield use.
The first global analysis of how marine environments react to the ever-increasing levels of CO2 that humanity is pumping into the atmosphere does not bode well at all for tomorrow’s would-be fishers. Published today in the journal Proceedings of the National Academy of Sciences (PNAS), the work of the University of Adelaide’s marine ecologists states that the warming and expected ocean acidification is likely to produce a reduction in diversity and numbers of various key species that underpin marine ecosystems around the world.
Researchers stumbled upon a new tool to fight cancer in a rather unexpected place; while searching for a vaccine against malaria in pregnant women, a team of Danish scientists found that, simply put, armed malaria proteins are remarkably good at killing cancer cells. They hope to have a working prototype ready for human trials within four years’ time. Their discovery has been published in the scientific journal Cancer Cell.
The Sulaymaniyah Museum in Iraq uncovered 20 new lines of the Epic of Gilgamesh, the nearly 3000 years old Mesopotamian poem, considered to be one of the world’s first great works of literature. They belong to a passage in which Gilgamesh enters a cedar forest and slays a demigod named Humbaba, with the setting and the demigod himself described differently and in more detail, writes Ted Mills for Open Culture.
With the variety of games available today varying from those designed to enhance mental fitness, solve real world problems all the way to ones meant for pure entertainment, they have diverse and profound effects on our brains. A new article published in the October 1st issue of Policy Insights from the Behavioral and Brain Sciences argues that the specific content, dynamics, and mechanics of individual games determine their effects on the brain and that the long-criticized action video games might have particularly positive benefits.
Among all the species with which we share the animal kingdom, pigs are the ones whose organs are best suited for transplant in human bodies — they are approximately the same size as our organs and have similar structures, making reconnecting blood vessels much easier. Pigs tend to have large litters and reproduce quickly, making them a very large, very accessible source of “spare parts.”
It’s estimated that humanity will have to produce around 50% more food than we currently do to keep up with growing global demand….by 2050. It’s an enormous challenge, especially as more and more countries face the effects of climate change, such as drought or toxic salinity levels. One of our best hopes is to rely more on crops that can flourish despite the vicissitudes of the environment, and plant cell biologists at the University of Oxford hope that their new breakthrough in climate-resilient agriculture will allow us to do just that.
The brain forms new thoughts using two adjacent brain regions that are the cornerstone of the process.
For most people listening to music or playing an instrument is a great way to relax, unwind, have fun, and express themselves. But not everybody is able to perceive, appreciate or memorize music, to sing or to dance. Monica is one such person, and to her, any kind of music is just a bunch of noise that makes her head ache and feel stressed.
This year’s Nobel Prize in Physiology or Medicine is split into three parts, being divided between William C. Campbell and Satoshi Ōmura — who jointly share a half “for their discoveries concerning a novel therapy against infections caused by roundworm parasites” — and Youyou Tu “for her discoveries concerning a novel therapy against Malaria.”
Material scientists at Oxford University, collaborating with experts from Karlsruhe, Munster and Exeter, have developed the world’s first light-based memory banks that can store data permanently. The device is build from simple materials, in use in CDs and DVDs today, and promises to dramatically improve the speed of modern computing.
Two drugs, currently prescribed to organ transplant patients to suppress their immune system after the procedure, show great promise as birth-control medicine for men, according to a study published in the journal Science.
When it comes to human waste products and pollutants, plastic claims the crown. There are very few things our planet can throw at it to get rid of the polymer. It becomes bendy and rippy and shredy but it just won’t go away. When you compound the resilience of this headstrong material with the sheer quantities of it that we dump into the oceans, it looks like a pretty one-sided battle that nature can’t win, despite all our desperate efforts to increase recycling and take it out of landfills.
But now it seems that mother nature still had a trick up her sleeve, and the non-biodegradable reign of plastic is about to come to an end, undermined by the heroic appetite of the mealworm.
North Carolina State University researchers have succeeded in proving that the crystalline structure of a material can be formed by disorder at an atomic level and not chemical bonds, by creating the world’s first entropy-stabilized alloy incorporating oxides.
Our ability to inhibit impulsive behaviors, to exercise willpower, is considered a core feature of the brain’s executive functions. This, along with others such as reasoning, working memory and attention regulate our thoughts and guide our behavior, allowing us to adapt them to the changing demands of our environment. But the effort our brain puts into refraining from impulses is so great that it can actually diminish its ability to form memories of the experience.
Fewer materials in nature rival the toughness and resilience of a tooth or a seashell, and it’s all due to their unique structure; viewed under powerful enough microscope, they reveal layers upon layers of micro-plates, perfectly aligned and fused together. Material scientists have long sought to produce something that imitates these structures, with comparable properties and complexity, but apart from nacre (mother-of-pearl) they’ve had very little success. Until now.
