How we make decisions depends on how uncertain we are
- ScienceDaily
- 19/9/9 23:08
A new study on how we use reward information for making choices shows how humans and monkeys adopt their decision-making strategies depending on the uncertainty of information present. The findings challenge one of the most fundamental assumptions in economics, neuroeconomics and choice theory that decision-makers typically evaluate risky options in a multiplicative way when in fact this only...
Acute periodontal disease bacteria love colon and dirt microbes
- ScienceDaily
- 19/9/9 23:08
Mythbuster: The idea that bacterial collaborations within microbiomes, like in the mouth, have evolved to be generous and exclusive very much appears to be wrong. In an extensive experiment, lavish collaborations ensued between random microbes. And some bacteria from the same microbiome were stingy with one another.

Success of gene therapy for a form of inherited blindness depends on timing
- ScienceDaily
- 19/9/9 23:07
An FDA-approved gene therapy for Leber congenital amaurosis, an inherited vision disorder with a childhood onset and progressive nature, has improved patients' sight. But new research on the blinding condition but new research underscores the importance of further investigation to halt the progression of the disorder.
The diet-microbiome connection in inflammatory bowel disease
- ScienceDaily
- 19/9/9 23:07
A change in diet is a go-to strategy for treating inflammatory bowel diseases like Crohn's. In dogs with a similar illness, researchers tracked specific changes in the microbiome as the pets went into remission. The team's findings, which mirror what is seen in children with Crohn's, could inform the design of improved therapeutic diets.
Teeth offer vital clues about diet during the Great Irish Famine
- ScienceDaily
- 19/9/9 22:01
Scientific analysis of dental calculus -- plaque build-up -- of the Famine's victims found evidence of corn (maize), oats, potato, wheat and milk foodstuffs.
Birds string together meaningless sounds to make 'words'
- ScienceDaily
- 19/9/9 22:01
A new study sheds light on whether animal vocalizations, like human words, are constructed from smaller building blocks. By analyzing calls of the Australian chestnut-crowned babbler, the researchers have for the first time identified the meaning-generating building blocks of a non-human communication system.
New drug may protect against memory loss in Alzheimer's disease
- ScienceDaily
- 19/9/9 22:01
A new drug discovered may protect against memory loss, nerve damage and other symptoms of Alzheimer's disease.
Rocks at asteroid impact site record first day of dinosaur extinction
- ScienceDaily
- 19/9/9 22:01
The research centers on the asteroid impact that wiped out non-avian dinosaurs, with the researchers getting the most detailed look yet of the aftermath that followed by examining the rocks and debris that filled the crater within the first 24 hours after impact.
Good at math? It means little if you're not confident
- ScienceDaily
- 19/9/9 21:42
Being good at math relates to better financial and medical outcomes -- unless you don't have confidence in your own abilities with numbers, new research suggests. In two studies, researchers found that the key to success in personal finances and dealing with a complex disease was a match between a person's math abilities and how comfortable and assured he or she felt using those skills.
To reduce pollution, policymakers should broaden focus beyond smokestacks
- ScienceDaily
- 19/9/9 21:42
Researchers used integrated assessment models to compute marginal damages from fine particulate matter-related emissions to measure economy-wide gross external damage due to premature mortality and other health outcomes.
Brain cells that suppress drug cravings may be the secret to better addiction medicines
- ScienceDaily
- 19/9/9 20:40
Scientists have shed light on poorly understood brain mechanisms that suppress drug and alcohol cravings, uncovering new insights that may help in the development of better addiction medicines.
Employee contract structures in startups can be determining factors of success
- ScienceDaily
- 19/9/9 20:33
Conventional wisdom in the startup community is that with the right incentives, the venture can meet and exceed expectations, and a major component of this is how you structure your contracts for founders and early employees. New research has found that when it comes to those contracts, it may be less about incentive, and more about identifying the right people to incentivize.
Liquid biopsies reveal genetic alterations linked to cancer drug resistance
- ScienceDaily
- 19/9/9 20:33
New research shows that liquid biopsies taken from blood provide a more complete picture than traditional biopsy of both the genetic diversity of a patient's cancer and how tumors evolve drug resistance at the molecular level.
World-record field strength for accelerator magnet
- ScienceDaily
- 19/9/9 20:33
Scientists have announced that they achieved the highest magnetic field strength ever recorded for an accelerator steering magnet, setting a world record of 14.1 teslas, with the magnet cooled to 4.5 kelvins or minus 450 degrees Fahrenheit. The previous record of 13.8 teslas, achieved at the same temperature, was held for 11 years.
How stress can weaken defenses
- ScienceDaily
- 19/9/9 19:49
Research shows how a dynamic regulation of a stress neurohormone regulates the trade-off between acute and long-term stress responses.
Deepest optical image of first neutron star merger

Scientists have observed how the human brain represents a familiar piece of music, according to research published in JNeurosci. Their results suggest that listening and remembering music involve different cognitive processes.
Ages of the Navajo Sandstone
- ScienceDaily
- 19/9/9 19:11
The Navajo Sandstone is known for its beautiful red and tan crossbedded sandstones that grace many of the national parks and monuments in the southwest USA. The sands were deposited in dunes within the largest known sand sea (erg) in Earth's history during the Early Jurassic. These deposits show a record of desertification -- the process by which fertile lands become desert. How did this landscape...
