Summary
Stem cell research in the USA is thriving, with significant funding and a leading number of publications. International collaborations are also a key feature of this growing scientific field.
Area of Science:
- Stem cell research
- Biomedical science
Background:
- Stem cell research faces political challenges but continues to grow in the USA.
- National Institutes of Health (NIH) funding for stem cell research has steadily increased.
- Significant investment is directed towards human embryonic stem cell research.
Purpose of the Study:
- To analyze the landscape of stem cell research in the USA.
- To quantify funding and publication output in stem cell research.
- To assess the extent of international collaboration in US-authored stem cell publications.
Main Methods:
- Analysis of funding data from the NIH.
- Bibliometric analysis of US-authored publications using ISI Web of Science.
- Tracking international co-authorship in scientific publications.
Main Results:
- In 2011, NIH funding for stem cell research reached approximately US$1.2 billion.
- US$123 million of the NIH funding was allocated to human embryonic stem cell research.
- Over 4000 US-authored stem cell publications were released in 2011, representing 38% of the global total.
- Approximately 25% of these US publications involved international collaborations.
Conclusions:
- The USA is a dominant force in global stem cell research.
- Continued growth in funding and publication output highlights the vitality of US stem cell science.
- International collaboration is a significant aspect of US stem cell research, fostering global scientific exchange.

01:26FDA Approved Drugs: Changes to Approved Drugs
Post-approval, manufacturers may modify an approved new or generic drug product. Such modifications can encompass alterations in the Active Pharmaceutical Ingredient (API), manufacturing process, formulation, batch size, manufacturing site, and container closure system (FDA Guidance for Industry, April 2004). Often, a drug product may undergo multiple changes.These modifications require careful evaluation to determine their potential impact on the drug product's identity, strength, quality,...
01:28Global Regulatory Systems
Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...
01:26Errors in Global Positioning System
Global Positioning System (GPS) technology has revolutionized navigation and positioning, but its accuracy is often compromised by various errors. These errors, stemming from environmental, satellite, and receiver-related factors, require careful mitigation to ensure reliable performance across applications.Atmospheric ErrorsGPS signals travel through the Earth’s ionosphere and troposphere, introducing delays which affect accuracy. The ionosphere is strongly influenced by charged particles,...
01:30Types of Global Positioning System Surveys
GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

The Global Positioning System (GPS) has become an indispensable tool in fieldwork, offering unparalleled precision and efficiency for surveying, navigation, and infrastructure development. By harnessing signals from a constellation of satellites, GPS receivers determine the location of objects with remarkable speed and accuracy, often completing calculations within a second.Advantages of Modern GPS TechnologyContemporary GPS receivers are designed to meet the practical demands of field...
01:13SI Units: 2019 Redefinition
Measurement is an indispensable part of analytical chemistry. The result of measurement helps quantify a substance's physical property and compare it with the physical property of another substance. Each measurement comprises two components - a number indicating the magnitude and a unit of measurement as a standard for comparison. Further, the same quantity can be measured using different units of measurement, which leads to differences in magnitude.
