Researchers have developed a photosensitive silicone intraocular lens that can be adjusted after surgery to eliminate refractive errors. The lens uses low-power light to make precise power adjustments, offering a potential alternative to LASIK surgery for severe myopia and farsightedness.
A study at the Great Lakes meeting revealed that organically-grown oranges contain 30% more vitamin C than conventionally-grown fruits, defying common assumptions. The reason for this difference is unclear but may be attributed to the use of nitrogen fertilizers in conventional farming practices.
Researchers at Advanced Cell Technology successfully transplanted cloned tissues into animals without rejection. The study's findings suggest that nuclear transplantation could provide a limitless supply of immune-compatible cells and organs for regenerative therapies, tackling one of the major challenges in transplantation medicine.
A national study found that only about a quarter of teachers used evidence-based programs, which emphasize social influences knowledge and refusal skills. The study suggests that teachers need resources and support to adopt and implement these effective programs.
Researchers used DNA microarrays to analyze 40% of the fruit fly genome and found that genetic changes are the result of many small contributors. The study's findings suggest that human genetic biases may also be caused by small changes in multiple genes.
Researchers at Boston Children's Hospital used therapeutic cloning to create functional tissue in cows, including heart, muscle, and kidney tissue. The cloned cells showed no rejection response, a promising development for treating diseases with stem cells.
The ACT EAB believes that this research represents an important milestone in demonstrating the feasibility of new therapies for tissue and organ repair. The board has established strict guidelines for human embryo research, including prohibiting culturing of human embryos in vitro for more than 14 days.
