Researchers at Boston University have developed a new DNA sequencing method that reduces the amount of DNA required for analysis, eliminating the need for time-consuming and error-prone DNA amplification. This breakthrough allows for faster and cheaper genome sequencing, enabling the analysis of long DNA strands in one swipe.
A study led by Dr. Frank Winkler followed the steps of tumor cell formation in real-time, revealing four stages required for metastasis development. Blocking angiogenesis with Avastin can suppress emergence of brain metastases.
Human carbon dioxide emissions impact ocean acoustics by increasing transparency to low-frequency sound, potentially affecting marine mammals' communication. The pH of surface seawater will drop by 0.6 units by 2100, leading to a 70% decrease in sound absorption.
Patients with NSCLC and EGFR mutations showed significantly improved progression-free survival with gefitinib treatment. Gefitinib was also better tolerated than chemotherapy, with fewer severe adverse events.
A new Yale University study suggests that current CO2 levels could lead to a greater temperature increase than previously thought, with temperatures potentially rising by 3 degrees Celsius or more. The research found that a relatively small rise in atmospheric CO2 was associated with substantial global warming during the mid- and early...
Researchers found that small increases in carbon dioxide led to substantial global warming about 4.5 million years ago. Slow changes in ice sheets and other factors amplify the effects of greenhouse gas composition.
Duke University engineers have created a new generation of lens that surpasses traditional lenses in focusing electromagnetic rays, with a wide angle of view and flat focal point. The lens is made from exotic composite materials known as metamaterials and has the potential to replace traditional optical systems.
Researchers at Emory University School of Medicine have determined the structures of two enzymes that customize histones, revealing insights into how DNA's packaging is crucial for gene regulation. The discovery may help doctors better understand or prevent inherited mental retardation.
