At one time scientists described DNA as fate. Now they know that DNA is potential, because experience—principally early life experience—plays a big part in how genes behave. The experience we’re talking about ranges from how your parents lived before you were conceived to how your mother felt and what she ate during pregnancy...
A team of scientists has identified a key regulator of developmental timing. The researchers...
Cold-blooded animals cannot regulate their body temperature, so their cells are stressed when...
cientists have generally believed that HIV and its monkey equivalent, SIV, gain a permanent foothold in the body very early after infection, making it difficult to completely eliminate the virus even after antiretroviral therapy has controlled it. Now researchers report that SIV can become entrenched in tissues fewer than 3 days after infection, before the virus is detectable in blood plasma (the liquid part) or blood cells.
In providing an effective safety and health program effective human resource management is critical. It includes development of accurate job descriptions to take into consideration job duties that may trigger the need for pre-employment evaluations and medical surveillance.
The Blue Line Cage consists of a wide range of cages, offering flexibility and an automatic watering system.
Access Technologies, a provider of infusion devices, has announced that it has completed the acquisition of the Solomon Scientific port, catheter and needle product lines.
This film shows some of the aspects of zebrafish production and maintenance. Zebrafish embryos, unlike mouse embryos, develop outside the mother's body and are transparent throughout the first few days of life.
The recently documented mistakes at federal laboratories involving anthrax, flu and smallpox have incited public outrage at the government’s handling of dangerous pathogens. But the episodes were just a tiny fraction of the hundreds that have occurred in recent years across a sprawling web of academic, commercial and government labs that operate without clear national standards or oversight, federal reports show.
Researchers have developed a powerful new single-cell technique to help investigate how the environment affects our development and the traits we inherit from our parents. This approach will boost understanding of embryonic development, could enhance clinical applications like cancer therapy and fertility treatments, and has the potential to reduce the number of mice currently needed for this research.
Learning the role of immune-system cells in healthy digestive tracts and how they interact with neighboring nerve cells may lead to new treatments for irritable bowel syndrome (IBS).
Omega-3 fish oil might help protect against alcohol-related neurodamage and the risk of eventual dementia, according to a study.
The IVIS SpectrumBL high-throughput 2D and 3D optical imaging system can simultaneously image up to 10 mice with full gas anesthesia incorporation along with ultra-high sensitivity to support bioluminescence, chemiluminescence, and Cerenkov radioisotopic imaging.
From the litter box to the laboratory, a microscopic organism native to cats shows promise in treating cancer. A mutated strain of T. gondii reprograms the natural power of the immune system to kill cells.
A study has identified a new signal that triggers the events leading to insulin resistance in obesity. The signal causes inflammation in adipose tissue and leads to metabolic disease, suggesting that blocking this signal may protect against the development of metabolic disease, type 2 diabetes, and other disorders caused by obesity-linked inflammation.
Cancer has left its "footprint" on our evolution, according to a study which examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species.
Researchers have discovered a possible explanation for the surprisingly large range of biological effects that are linked to a micronutrient called lipoic acid: It appears to reset and synchronize circadian rhythms, or the “biological clock” found in most life forms.
Glenbrook Technologies has been chosen by the University of Missouri School of Medicine to design and build a high resolution fluoroscopic x-ray system that has the ability to continuously monitor and record the gullet of a live mouse as it is swallowing.
