''Neuromorphic'' refers to mimicking the behavior of brain neural cells. When one speaks of neuromorphic computers, they are talking about making computers think and process more like human brains-operating at high-speed with low energy consumption.
There's good news for people with Parkinson's disease. A new study shows that deep brain stimulation may not increase the risk of developing dementia.
Now a new study has found there is no difference in developmental and behavioral outcomes for children who have febrile seizures after vaccination, children who have febrile seizures not associated with vaccination and children who have never had a seizure.
Often described as cosmic lighthouses, quasars are luminous beacons that can be observed at the outskirts of the Universe, providing a rich topic of study for astronomers and cosmologists. Now scientists have announced the discovery of the second-most distant quasar ever found, at more than 13 billion lightyears from Earth.
Native to Europe but discovered in Pennsylvania in 2015, the Allium leafminer is a fly whose larvae feed on crops in the Allium genus, including onions, garlic and leeks.
An analysis of over 800 academic research papers on physical health and exercise suggests that the level of popular media coverage for a given paper is strongly linked to the attention it receives within the scientific community.
Scientists have created a novel microbiome-based diagnostic tool that, with the accuracy of the best physicians, quickly and inexpensively identifies liver fibrosis and cirrhosis over 90 percent of the time in human patients. The non-invasive method relies on an algorithm to analyze patient stool samples -- which contains traces of what lives in the gut -- and could lead to improved patient care...
Researchers field-tested 14 active ingredients in insecticides, applied in a variety of methods, to understand the best treatment options against the Allium leafminer, a growing threat to onions, garlic and leeks.
In a new study published in the scientific journal Ecology, researchers from the University of Montana's Flathead Lake Biological Station may have unlocked a mystery surrounding unique aquatic insects in the Flathead watershed.
Life on Earth would likely not be possible without the Moon; it keeps our planet's axis of rotation stable, which controls seasons and regulates our climate. However, there has been considerable debate over how the Moon was formed. The popular hypothesis contends that the Moon was formed by a Mars-sized body colliding with Earth's upper crust which is poor in metals. But new research suggests the...
Ancient submerged Aboriginal archaeological sites await underwater rediscovery off the coast of Australia, according to a study.
A new study found that the Ultra Music Festival was likely stressful to toadfish.
Engineering researchers have developed soft robots inspired by jellyfish that can outswim their real-life counterparts. More practically, the new jellyfish-bots highlight a technique that uses pre-stressed polymers to make soft robots more powerful.

Worldwide there is a growing demand for animal products for human nutrition, despite vegan and vegetarian diets becoming more popular in Western countries. Changing diets necessitate a substantial amount of protein as an input for animal production. Future protein feedstuffs will need to become independent of arable land in order to avoid further land use changes, such as deforestation.
A new study of wildlife consumption in northern Laos by San Diego Zoo Global researchers found widespread use of products made from sun bears, Asiatic bears and serows—goat-like mammals found throughout Asia—among other vulnerable species. The findings indicate that efforts are needed to reduce the unsustainable harvest of bears and serows, in particular, "before this demand becomes a...
A new study published in the Journal Environmental Pollution by researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science found that the Ultra Music Festival was likely stressful to toadfish.
Whether it's sending the grandparents a few pictures of the kids, streaming a movie or music, or surfing the Internet for hours, the volume of data our society generates is increasing all the time. But this comes at a price, since storing data consumes huge amounts of energy. Assuming that data volumes continue to grow in future, the related energy consumption will also increase by several orders...

The first underwater Aboriginal archeological sites have been discovered off northwest Australia dating back thousands of years ago when the current seabed was dry land.
A team of researchers at the University of Tokyo and Fudan University has studied the process of crystallization when more than one structural arrangement is possible. By reducing the noise from random fluctuations, they found that transient precursors of the various crystalline orderings coexist and compete with each other. This work may help lead to more efficient crystal engineering methods.
An analysis of over 800 academic research papers on physical health and exercise suggests that the level of popular media coverage for a given paper is strongly linked to the attention it receives within the scientific community. P. Sage Anderson and colleagues at Brigham Young University in Provo, Utah, report these findings in the open-access journal PLOS ONE on July 1, 2020.
The UK government needs to be more rigorous and transparent with information if regional outbreaks of Covid-19 are to be containedIn the game of whack-a-mole, the target pops up in one location and, once hammered down, appears immediately somewhere else. The defining features of the exercise are randomness and futility, which makes it an unfortunate metaphor for Boris Johnson to use for his...
Worldwide there is growing demand for animal products for human nutrition, despite the popularity of plant-based diets. This means more feed is needed for animals. Future feedstuffs will need to be produced without exacerbating deforestation. Insects and microalgae are up-and-coming sectors to meet protein demands for humans and animals. Therefore, researchers nvestigated whether these alternative...
Researchers have demonstrated that they can combine iPhone videos shot 'in the wild' by separate cameras to create 4D visualizations that allow viewers to watch action from various angles, or even erase people or objects that temporarily block sight lines.
Scientists are whispering the secrets of a simpler way to generate the sensory cells of the inner ear. Their approach uses direct reprogramming to produce sensory cells known as 'hair cells,' due to their hair-like protrusions that sense sound waves.
Scientists have developed a method allowing for the long-term culture of 'pancreatic slices' to study the regeneration of the human pancreas in real time.

Scientists have shown how even low doses of neonicotinoid insecticides, as they may realistically occur in contaminated soils, adversely affect the development of black garden ants (Lasius niger). This study highlights the need to overthink current deployment and management of chemical pest control for more sustainable agriculture.
