A brain-controlled prosthetic limb have shown that machine learning techniques helped an individual with paralysis learn to control motion using their brain activity without requiring extensive daily retraining.
It is proof-of-concept for how future models can overcome limitations of prior brain-computer interface efforts, which existing had to be reset and recalibrated each day, almost like asking someone to learn to ride a bike over and over again each day.
Children learn languages much easier than adults, and also seem to recover from neural injuries better. The reason may be that adults process most discrete neural tasks in specific areas in one or the other of their brain's two hemispheres, while kids use both the right and left hemispheres to do the same task.
If you are a tourist and visit California in the United States or Bavaria in Germany, you will quickly notice it is not like a lot of other places in those countries. A cultural mentality exists and people who identify with the stereotype are more likely to stay or even move there.A new paper
finds that people who live in mountain regions of the U.S. maintain more of that sensibility even in the modern era. Historian Frederick Jackson Turner, a Harvard academic, presented his thesis on the US frontier in 1893, describing the "coarseness and strength combined with acuteness and acquisitiveness" it had forged in the American character.
You can't market a "Tennessee whiskey" unless it goes through charcoal filtration called the Lincoln County Process, named such after the locale of the original Jack Daniel's distillery.
Charcoal is not exclusive to American blended whiskey, this type of filtration is a common step in the production of distilled beverages, including vodka and rum, but while "charcoal mellowing" in Tennesse Whiskey varies from manufacturer to manufacturer, they all involve passing the fresh whiskey distillate through a bed of charcoal, usually derived from burnt sugar maple, prior to barrel-aging the product.
The reopening of cafes has been one of the highlights of relaxed COVID-19 restrictions for many Australians. During lockdowns, long queues for takeaway coffee were testimony to caffeine’s relevance to our lives.
As every other aspect of human life, science communication has suffered a significant setback due to the ongoing Covid-19-induced pandemic. While regular meetings of scientific teams can be effectively held online, through zoom or skype, it is the big conferences that are suffering the biggest blow. And this is not good, for several reasons.
When you think of shrimp, lobster, or crabs, you don't think of the hottest place on Earth, but a new freshwater Crustacea has been discovered during an expedition of the desert Lut, which is the record-holder for temperature on land. The Lut desert, Dasht-e Lut in Farsi, is the second largest desert in Iran.
Almost deprived of vegetation, the Lut desert harbors a diverse animal life, but no permanent aquatic biotops, such as ponds. Instead, after rain falls, non-permanent astatic water bodies are filled including the Rud-e-Shur river from north-western Lut. And that is when these new creatures can be more readily found.
The compound melittin, found in honeybee venom, rapidly destroyed triple-negative breast cancer and HER2-enriched breast cancer cells in a recent study
. In the 1950s, bee venom was found to reduce the growth of tumors in plants and in the last two decades interest grew into the effects of honeybee venom on different cancers.
For the study, 312 honeybees and bumblebees in Perth Western Australia, Ireland and England, were used to test the effect of the venom on the clinical subtypes of breast cancer, including triple-negative breast cancer, which has limited treatment options.
Findings based on a SIR (Susceptible, Infectious or Recovered) Model of Infection Dynamics, commonly used to determine infection scenarios, including COVID-19, and presented
at the Artificial Intelligence and the Coronavirus workshop at the International Conference on Artificial Intelligence in Medicine, say that New York and California may have reached herd immunity.
Two studies of people who had completed personality assessments as undergraduates or MBA students at three universities, and were surveyed again over a decade later and ranked by co-workers about their workplace behavior, found that those with selfish, deceitful, and aggressive personality traits were not more likely to have attained power than those who were generous, trustworthy, and generally nice.
Plenty of jerks were in positions of power, but it wasn't because they manipulated their way into it.
