Unraveling the genetic determinants of small vessel vasculitis
Researchers from the University of Tsukuba have shown that the single-nucleotide variants of TERT and DSP, which promote risk for idiopathic pulmonary fibrosis (IPF), are significantly associated with susceptibility to microscopic polyangiitis and myeloperoxidase-ANCA associated vasculitis. Interestingly, there was no clear link to the severe complication interstitial lung disease (ILD). These...
Venous origin of brain blood-vessel malformations
In the condition known as cavernoma, lesions arise in a cluster of blood vessels in the brain, spinal cord or retina. Researchers from Uppsala University can now show, at molecular level, that these changes originate in vein cells. This new knowledge of the condition creates potential for developing better therapies for patients. The study has been published in the journal eLife.
Vitamin E from palm oil useful in boosting immune response based on studies on liver cells
Palm oil is an economical source of vitamin E, and several studies have shown the beneficial effects on the immune system, which include anti-oxidant and anti-cancer activity as well has cytoprotective actions. Researchers hope that these findings pave the way for easily available remedies for a variety of diseases. The current study is published in Current Pharmaceutical Biotechnology.
Your favorite music can send your brain into a pleasure overload
Electroencephalography (EEG) has been used as a novel technique to show how cortical activity, related to the reward-system, happens in the brain when people experience a musical "chill". The new study yields an in-depth view into how organic chills are produced in natural musical settings, and why they might occur.

How social media sites plan to handle premature election declarations
The election results will start to come in as early as 7pm Eastern Time on Tuesday, when seven states begin closing the polls. The next few hours will see more polls close around the country, more votes processed, more counts updated. But we won’t have the final result that night.This isn’t unusual: In the US, counting votes and officially certifying them always goes on longer than...

New simulation finds max cost for cost-effective health treatments
- ScienceDaily
- 20/11/2 23:32
As health care costs balloon in the U.S., experts say it may be important to analyze whether those costs translate into better population health. A new study analyzed existing data to find a dividing line - or ''threshold - for what makes a treatment cost-effective or not.

- ScienceDaily
- 20/11/2 23:32
Solar power has shown immense potential as a futuristic, 'clean' source of energy. No wonder environmentalists worldwide have been looking for ways to advance the current solar cell technology. Now, scientists have put forth an innovative design for the development of a high-power transparent solar cell. This innovation brings us closer to realizing our goal of a sustainable green future with...
Two centuries of Monarch butterflies show evolution of wing length
- ScienceDaily
- 20/11/2 23:32
North America's beloved Monarch butterflies are known for their annual, multi-generation migrations in which individual insects can fly for thousands of miles. But Monarchs have also settled in some locations where their favorite food plants grow year round, so they no longer need to migrate. A new study of specimens collected over the last two centuries shows how wing length evolves in response...
COVID-19 'super-spreading' events play outsized role in overall disease transmission
- ScienceDaily
- 20/11/2 23:32
Researchers find COVID-19 super-spreading events, in which one person infects more than six other people, are much more frequent than anticipated, and that they have an outsized contribution to coronavirus transmission.
Rapid method finds potent COVID-19 monoclonal antibody among a trillion possibilities
- ScienceDaily
- 20/11/2 23:32
Scientists have discovered the fastest way to identify potent, neutralizing human monoclonal antibodies against SARS-CoV-2, the virus that causes COVID-19. The method -- as well as a trio of successful animal studies on an antibody called 'Ab1' -- are described today in a new study. Ab1 is on track for human clinical trials by early next year.

- 20/11/2 22:26
What are the secrets behind one of the most successful fantasy series of all time? How has a story as complex as 'Game of Thrones' enthralled the world and how does it compare to other narratives? Researchers from five universities across the UK and Ireland came together to unravel 'A Song of Ice and Fire', the books on which the TV series is based.
Self-watering soil could transform farming
- ScienceDaily
- 20/11/2 22:26
A new type of soil created by engineers can pull water from the air and distribute it to plants, potentially expanding the map of farmable land around the globe to previously inhospitable places and reducing water use in agriculture at a time of growing droughts.
Lizard skull fossil is new and 'perplexing' extinct species
- ScienceDaily
- 20/11/2 22:26
A new species of extinct lizard, Kopidosaurus perplexus, has just been described. The first part of the name references the lizard's distinct teeth; a 'kopis' is a curved blade used in ancient Greece. But the second part is a nod to the 'perplexing' matter of just where the extinct lizard should be placed on the tree of life.

- 20/11/2 21:08
Neanderthals behaved not so differently from us in raising their children, whose pace of growth was similar to Homo sapiens. Thanks to the combination of geochemical and histological analyses of three Neanderthal milk teeth, researchers were able to determine their pace of growth and the weaning onset time. These teeth belonged to three different Neanderthal children who have lived between 70,000...

Bats can predict the future, researchers discover
- ScienceDaily
- 20/11/2 21:08
They can't tell fortunes and they're useless with the stock market but bats are quite skilled at predicting one thing: where to find dinner. Bats calculate where their prey is headed by building on-the-fly predictive models of target motion from echoes, researchers find. The models are so robust, bats can continue to track prey even when it temporarily vanishes behind echo-blocking obstacles like...
