Burning and tingling in your feet? You may have small fiber neuropathy
- ScienceDaily
- 21/10/27 23:26
The number of people experiencing numbness, tingling and pain in their feet with no known cause has been increasing over the last two decades, according at a new study. Called small fiber neuropathy, the condition has different symptoms than large fiber neuropathy, which can cause weakness and balance issues. But in many cases people have both types of neuropathy.
Astronomers discover massive galaxy 'shipyard' in the distant universe
- ScienceDaily
- 21/10/27 23:26
Astronomers have discovered a structure thought to be a 'protocluster' of galaxies on its way to developing into a galaxy supercluster. Observations show the protocluster, which is located 11 billion light-years from Earth, as it appeared when the universe was 3 billion years old, when stars were produced at higher rates in certain regions of the cosmos.

Evidence of prehistoric human activity in Falkland Islands
- ScienceDaily
- 21/10/27 21:07
Findings from a new study suggest that Europeans were not the first people to ever set foot on the Falkland Islands. Most of the evidence from the investigation indicates that Indigenous South Americans likely traveled to the Falkland Islands between 1275 C.E. and 1420 C.E., although earlier dates cannot be ruled out.

Not all acne is equal: Scientists reveal strains of C. acnes that promote skin health
- ScienceDaily
- 21/10/27 19:49
Researchers reveal correlation between ribotype (RT) strains of Cutibacterium acnes, which are found in human skin, and the lifespan of the nematode Caenorhabditis elegans. Strains RT4 and 8, which are associated with acne in human skin, shortened the lifespan of the nematode, while RT6, which are predominantly found in healthy human skin, did not. Also, it was found that the healthy skin-related...

For knee replacement patients, physical therapy reduces risk of chronic opioid use
- ScienceDaily
- 21/10/27 18:21
Even low levels of physical therapy were associated with lower risk of chronic opioid use after total knee replacement. The team's analysis of over 67,000 patient records revealed that the longer a patient waits to start physical therapy, the greater the eventual odds of chronic opioid use.
All about Eve, sophisticated AI
- ScienceDaily
- 21/10/27 18:21
New AI model called EVE outperforms other AI methods in determining whether a gene variant is benign or disease-causing. When applied to more than 36 million variants across 3,219 disease-associated proteins and genes, EVE indicated more than 256,000 human gene variants of unknown significance that should be reclassified as benign or pathogenic. Used in combination with current clinical tools, EVE...
Twenty-four trillion pieces of microplastics in the ocean and counting
- ScienceDaily
- 21/10/27 18:21
Based on a total of 8,218 pelagic microplastic samples from the world's oceans collected between 2000 and 2019, a team of scientists has developed a publicly available dataset for assessing the abundance of microplastics and their long-term trend in the world's upper oceans. The team found 24.4 trillion pieces (82,000--578,000 tons) of microplastics in the world's oceans, but the actual amount is...
