Mitochondrial mutation increases the risk of diabetes in Japanese men
- ScienceDaily
- 21/1/21 21:38
A new study of Type 2 diabetes (T2D) in Japanese populations has uncovered a previously uncharacterized genetic variant that puts male carriers at greater risk for the disease, as well as the mechanism by which it does so. The impact of the variant was most pronounced in sedentary men; those with the variant had a 65% greater rate of T2D than sedentary men without it.
Solar system formation in two steps
- ScienceDaily
- 21/1/21 21:10
Researchers have discovered that a two-step formation process of the early Solar System can explain the chronology and split in volatile and isotope content of the inner and outer Solar System.
Squeezing a rock-star material could make it stable enough for solar cells
- ScienceDaily
- 21/1/21 21:10
A promising lead halide perovskite is great at converting sunlight to electricity, but it breaks down at room temperature. Now scientists have discovered how to stabilize it with pressure from a diamond anvil cell. The required pressure is well within the reach of industrial manufacturing requirements.
Designing customized 'brains' for robots
- ScienceDaily
- 21/1/21 21:09
Researchers have developed an automated way to design customized hardware that speeds up a robot's operation. The system, called robomorphic computing, accounts for the robot's physical layout in suggesting an optimized hardware architecture.
Spitting Cobra venom reveals how evolution often finds the same answer to a common problem
- ScienceDaily
- 21/1/21 21:09
A study of spitting cobras reveals how a combination of venom components have evolved to create an instantly painful venom, not once, but on three separate occasions.
A closer look at T cells reveals big differences in mild vs. severe COVID-19 cases
- ScienceDaily
- 21/1/21 21:09
How long does immunity to SARS-CoV-2 last following infection? Researchers have uncovered an interesting clue. Their new study suggests that people with severe COVID-19 cases may be left with more of the protective 'memory' T cells needed to fight reinfection.
Combining best of both worlds for cancer modeling
- ScienceDaily
- 21/1/21 21:09
Treatment options for many types of cancers remain limited, due partly to the in vitro tools used to model cancers and that results from animal studies do not always translate well to human disease. These shortcomings point to a clear need for a better, patient-specific model. Researchers suggest bioengineered microscale organotypic models can address this need.
Study finds genetic clues to pneumonia risk and COVID-19 disparities
- ScienceDaily
- 21/1/21 21:09
Researchers have identified genetic factors that increase the risk for developing pneumonia and its severe, life-threatening consequences.
When a story is breaking, AI can help consumers identify fake news
- ScienceDaily
- 21/1/21 21:09
Warnings about misinformation are now regularly posted on Twitter, Facebook, and other social media platforms, but not all of these cautions are created equal. New research from Rensselaer Polytechnic Institute shows that artificial intelligence can help form accurate news assessments -- but only when a news story is first emerging.
Why older adults must go to the front of the vaccine line
- ScienceDaily
- 21/1/21 21:09
A new global, mathematical modeling study shows that in most cases prioritizing older adults for COVID-19 vaccines saves the most lives. It also found that, in some cases, more lives could be saved and infections prevented if those who've already tested positive step to the back of the line.
How to get more electric cars on the road
- ScienceDaily
- 21/1/21 21:09
Researchers reveal the kinds of infrastructure improvements that would make the biggest difference in increasing the number of electric cars on the road, a key step toward reducing greenhouse gas emissions from transportation.
Researchers prove fish-friendly detection method more sensitive than electrofishing
- ScienceDaily
- 21/1/21 21:09
Delivering a minor electric shock into a stream to reveal any fish lurking nearby may be the gold standard for detecting fish populations, but it's not much fun for the trout. Scientists have found that sampling stream water for evidence of the presence of various species using environmental DNA, known as eDNA, can be more accurate than electrofishing, without disrupting the fish.
'Aging well' greatly affected by hopes and fears for later life

COVID-19 infection in immunodeficient patient cured by infusing convalescent plasma, doctors report
- ScienceDaily
- 21/1/21 21:09
Under FDA emergency-use authorization, doctors successfully resolved COVID-19 in a seriously ill, immunodeficient woman using a very high-neutralizing antibody-titer convalescent plasma from a recovered COVID-19 patient. However, further study suggested that use of convalescent plasma may not be warranted in many cases, for two reasons: 1) titer levels are too low in many convalescent plasmas, and...
