Researchers have found that widespread transfer of genes between species has radically changed the genomes of today's mammals. L1 and BovB jumping genes were transferred between 759 species across various domains of life, including plants, animals, fungi, reptiles, and insects.
Researchers identified clusters of circulating tumour cells in blood samples from patients with locally advanced head and neck cancer, which had not spread to other organs. The presence or absence of these clusters was associated with the spread of cancer to other organs.
Young baseball players who exceed pitch count limits are more prone to elbow injuries. Researchers found that throwing high numbers of pitches per day and games played were associated with an increased risk of pain.
A new study shows that young patients who underwent surgery for isolated meniscus tears between 1990 and 2005 experienced significant improvements in functional outcomes. The average IKDC score increased from pre-operative levels, indicating a lasting improvement in knee health.
