On The High Horse: Why Dominant Individuals Climb The Proverbial Ladder
- ScienceDaily
- 08/4/24 10:50
Psychological findings imply that a person's level of dominance could be measured based on their biases favoring vertical representations of power, as is the case in a hierarchy. In an attempt to grasp complex concepts, humans have tried to represent abstractions like power and dominance through visually-stimulated metaphors such as pyramids and steeples. And dominance especially has been measured...

Researchers suggest that stromal cells derived from menstrual blood may represent a potentially unlimited, ethically unencumbered, easily collectable and inexpensive source of stem cells for use in regenerative medicine. The study found that MenSCs are easily expandable to clinical relevance and express multipotent markers at both the molecular and cellular level. The abundance and plasticity of...
Primary Driver Of Stomach Cancer Development Identified
- ScienceDaily
- 08/4/24 10:50
Scientists have discovered what appears to be the primary driver of tumor development in the stomach. Inhibiting the signaling cascade initiated by the IL-11 protein prevented the development of inflammation, hyperplasia (an abnormal increase in the number of cells) and tumor formation in pre-clinical models of gastric...

The influence of genetics increases as young women transition from their first drink to alcohol dependence. Researchers found that although environment is most influential in determining when drinking begins, genes play a larger role in advancing to problem drinking and alcohol...
Transgenic Papaya Genome Draft Yields Many Fruits
- ScienceDaily
- 08/4/24 10:50
Researchers have produced a first draft of the papaya genome. This draft sheds new light on the evolution of flowering plants. And because it involves a genetically modified plant, the newly sequenced papaya genome offers the most detailed picture yet of the genetic changes that make the plant resistant to the papaya ringspot...

- ScienceDaily
- 08/4/24 10:50
Researchers have developed a method to calculate how a device can provide maximum functionality with a minimum quantity of processor and memory capacity. TVs, DVD players and mobile phones can malfunction when the inbuilt chips and software cease to cope with the increasingly large flow of...
Newly Created Microbe Produces Cellulose And Sugars For Biofuels
- ScienceDaily
- 08/4/24 10:50
A newly created microbe produces cellulose that can be turned into ethanol and other biofuels, report scientists. They say the microbe could provide a significant portion of the nation's transportation fuel if production can be scaled up.
Pregnancy Is Possible After Cancer Treatment
- ScienceDaily
- 08/4/24 10:50
It has been reported for the first time in Germany that healthy ovarian tissue has been taken from a nonpregnant woman with cancer and then reimplanted after cancer therapy. The patient is now 32-years-old, and could become pregnant as a result.
Scientists Unravel Heparin Death Mystery

- 08/4/24 10:50
Scientists have explained how contaminated batches of the blood-thinner heparin were able to slip past traditional safety screens and kill dozens of patients recently in the United States and Germany.
Benefits Of Omega-3s Still Unclear For Bipolar Disorder
- ScienceDaily
- 08/4/24 08:00
Despite intriguing findings that omega-3 fatty acid supplements could alleviate depression symptoms, there is still not enough evidence to say whether omega-3s are useful treatments for people with bipolar disorder, according to a review of recent studies. Nevertheless, omega-3s deserve further study, since they seem to have no serious side effects and most experts recommend the supplements for...
Costs, Considerations Of Switching To Natural Or Organic Agricultural Methods
- ScienceDaily
- 08/4/24 08:00
The definition of "organic" is defined by the US Department of Agriculture; "natural," however, can be defined differently depending on who's doing the labeling. But both terms mean one thing: higher costs for producers. That's why researchers hope to provide another tool to help those in the beef industry pondering whether to abandon conventional methods and go natural or...
Drug-releasing Stent Shows Promise For Improving Outcomes In Patients With Coronary Artery Disease
- ScienceDaily
- 08/4/24 08:00
For patients who underwent angioplasty to open narrowed coronary arteries, the use of stents releasing the drug everolimus reduced the rate of renarrowing of the arteries and significantly reduced the risk of major cardiac events, compared to the widely-used paclitaxel-releasing stents, according to a new...
Human Brain Appears 'Hard-wired' For Hierarchy
- ScienceDaily
- 08/4/24 08:00
Human imaging studies have for the first time identified brain circuitry associated with social status. Researchers found that different brain areas are activated when a person moves up or down in a pecking order -- or simply views perceived social superiors or inferiors. Circuitry activated by important events responded to a potential change in hierarchical status as much as it did to winning...
Lumbar Supports Not Particularly Effective For Low Back Pain
- ScienceDaily
- 08/4/24 08:00
Lumbar or lower back supports -- those large belts that people wear around their waists when they lift or carry heavy objects -- are not very useful for preventing low back pain, according to a new systematic review. Although many people use lumbar supports to bolster the back muscles, they are no more effective than lifting education -- or no treatment whatsoever -- in preventing related pain or...
Galaxies Gone Wild: Dramatic Collisions Trigger Bursts Of Star Formation
- ScienceDaily
- 08/4/24 06:00
Interacting galaxies are found throughout the Universe, sometimes as dramatic collisions that trigger bursts of star formation, on other occasions as stealthy mergers that result in new galaxies. Galaxy mergers, which were more common in the early Universe than they are today, are thought to be one of the main driving forces for cosmic evolution, turning on quasars, sparking frenetic star births...
