A 2.5-year study involving 2,781 individuals aged 15-65 found the acellular pertussis vaccine to be safe and 92% effective in preventing the disease among adults and adolescents. The vaccine's effectiveness could help reduce transmission of the disease.
Scientists have discovered a specific signaling pathway, PKA, that is crucial for T-cell activation and immune function. In microgravity, this pathway fails to respond to pathogens, leading to severe T-cell suppression.
New research confirms a century-old theory that genetic instability caused by duplicate genomes can lead to tumor formation. The study found that cells with extra chromosomes and centrosomes are more likely to become malignant, making them vulnerable to certain cancer treatments.
A study published in the New England Journal of Medicine found that cooling newborns to prevent death and injury from oxygen deprivation during birth may reduce infant disability and death. After 18-22 months, 44% of cooled infants developed moderate to severe disabilities or died, compared to 62% of those receiving standard care.
A worldwide compilation of exceptionally preserved fossil assemblages suggests that prehistoric global warming may have led to the formation of these fossils. The widespread death and burial of animals and their carbon created fossil bonanzas, potentially saving Earth from a heat sterilization event like Venus.
Women with endometriosis often experience chronic pain, reduced quality of life, and suicidal feelings due to delayed diagnosis. The study highlights the need for better awareness and pain management services for this condition.
Researchers will investigate whether vitamin E and/or selenium can reduce skin and other cancers. The study aims to provide essential data on potential low-cost interventions for millions at risk of arsenic-induced cancers in Bangladesh and globally.
The new ASTRO/ASRT grant program aims to establish new radiation therapy programs, addressing significant shortages in the field. Currently, there are only 71 accredited educational programs in the US, down from 125 a decade ago, and 13 states have no radiation therapy program.
A two-week survey of over 600 kilometers of Aceh's southwest coast will examine the damage to coral reefs caused by the December 2004 earthquake and tsunami. The survey aims to understand the extent of the damage and provide insight into the natural recovery process.
Researchers discover that Cut, a DNA-binding protein, plays a crucial role in regulating cell proliferation by accurately transcribing Notch signals. Inaccurate transcription leads to unregulated growth and can be linked to various diseases such as Alzheimer's, cancer, and genetic disorders.
