A fatal mine collapse in Utah's Crandall Canyon coal mine was actually a massive cave-in that covered an area of approximately 50 acres. New calculations reveal the disaster began near where miners were excavating and quickly grew to four times its initially estimated size.
Researchers found that metastatic prostate tumors produce significant levels of testosterone, fueling cancer growth despite low circulating androgen levels. This discovery suggests targeting the tumor itself, rather than systemic hormone suppression, to develop more effective treatments for all stages of prostate cancer.
A recent study highlights the importance of understanding C. difficile's toxins and virulence factors, which can cause severe hospital-acquired infections. The research also explores the bacteria's transmission, symptoms, and treatment options, including the development of a potential 'designer' probiotic.
A new University of Melbourne study found that nearly one in five working women and one in eight working men experience preventable depression caused by job stress. The study estimates that more than 21,000 cases of preventable depression are caused by job stress each year.
Scientists have discovered two novel compounds produced by soil bacteria that show promise in combating MRSA infections and cancer. The breakthroughs come after years of genome mining, which identifies pathways to produce new compounds from microbial DNA sequences.
A prototype of a sturdy bamboo house was built in under two weeks with a modular design that can be adjusted for specific family needs. The structure is made from processed bamboo veneer sheets and is fireproof, insulated for heat and sound, and sustainable.
Current prenatal biochemical screening tests only detect half of chromosomal abnormalities, including trisomies and deletions. This limitation emphasizes the importance of counseling patients on the limitations of these tests to make informed decisions about invasive diagnostic testing.
Researchers combined two biotherapies to induce an anti-tumor response, showing a 19% overall response rate in stage 4 melanoma patients. The treatment was found to be tolerable in terms of toxicity.
A study of 97 couples found that fathers are more involved in infant care when their wives provide active encouragement, regardless of their own beliefs or the quality of parenting. Encouragement from mothers can either foster or limit fatherly participation, with mothers acting as 'gatekeepers' to their involvement.
A genetic mutation in the VLDLR gene is implicated in quadrupedal locomotion in four families affected by Unertan syndrome. Despite shared DNA regions across chromosomes, distinct genes are responsible for the condition in each family.
Ecosystems are increasingly connected by human activities such as transportation and land use. This can lead to
Researchers at the University of Guelph found that first-year college students gained an average of 5.29 pounds, not 15 pounds, over six months. The study also highlights the importance of educating employees on food safety measures to reduce the risk of foodborne illness in restaurants.
A new study found that people who choose not to express their thoughts and feelings after experiencing a collective trauma, such as a school shooting or terrorist attack, may be better off than those who do talk about their feelings. The research suggests that it's okay to keep emotions inside in the immediate aftermath of a tragedy.
A pilot study at Duke University Medical Center found that disabling a protein on melanoma cells makes them more vulnerable to chemotherapy, resulting in complete responses in 8 out of 16 patients. The compound ADH-1 was tested in combination with chemotherapy and showed promising results.
