A team of University of Chicago scientists has developed a new micro-western array technology that enables the examination of hundreds of proteins simultaneously. This breakthrough may lead to more precise diagnoses and individualized treatments for cancers and other diseases.
Researchers at Dana-Farber Cancer Institute discovered a gene activity signature predicting high cancer recurrence risk in breast tumors treated with chemotherapy drugs. The study suggests that these tumors may still be vulnerable to other types of chemotherapy agents.
A study published in Nature Structural & Molecular Biology reveals that a genetic mutation disrupts an array of metabolic pathways in muscle cells by affecting two key proteins. The loss of either protein accounts for most molecular abnormalities associated with the disease, while loss of both also seems to play an important role.
Researchers at the University of Western Ontario used state-of-the-art micro-computed tomography systems to collect detailed 3D scans of bat internal anatomy. The study identified a unique bone connection that distinguishes bats using laryngeal echolocation from those using tongue clicks.
Researchers discovered that two related photoreceptor proteins found in monarch butterflies can mediate magnetoreception by an unconventional photochemical mechanism. The study provides the first genetic evidence for a vertebrate-like Cry protein functioning as a magnetoreceptor in animals.
Researchers at the University of Utah have found that natural cavities in polymers can act like mirrors in light-emitting materials, generating 'random' lasers. This discovery could lead to new applications in cancer diagnosis and other fields.
A recent study found that midwife toads living in mountain regions are highly susceptible to a serious fungal infection called chytridiomycosis, which can lead to up to 100% mortality rates. Conservationists may be able to limit the impact of the disease by ensuring tourists do not transfer it between lakes.
Researchers at the Southwest Research Institute suggest that differences in cometary impacts and melting patterns explain Ganymede and Callisto's distinct surfaces. The study reveals that Ganymede received more intense impacts, leading to deeper melting and a heavier core.
A new experiment has confirmed that a levitating magnet can create a dense plasma, a crucial step in achieving fusion reactions. The findings offer a potential new path to fusion energy, which could provide a long-term solution to the planet's energy needs without contributing to global warming.
