Researchers have successfully increased normal life span in nematode worms through the use of synthetic catalytic scavengers, a new class of antioxidant drugs. The treatment extended mean life spans by approximately 50% and prevented early death in a mutant strain linked to oxidative stress.
Cornell University researchers reveal molecular motor Myo2p's crucial role in guiding the mitotic spindle during cell division. The study sheds light on an essential mechanism in new cell formation and highlights potential consequences of failures in molecular motor function.
A plant compound, cyclopamine, has been found to block the action of mutated cancer genes that produce basal cell skin carcinomas. The drug may be used to treat various types of cancers, including medulloblastomas in the brain and rhabdomyosarcomas in muscle.
A study finds that multinationals that adopt stringent global environmental standards in developing countries outperform those using laxer standards, averaging a $10.4 billion higher market value. The researchers suggest that firms that prioritize eco-efficient production systems may see increased productivity and profitability.
A comprehensive study by Cornell University expert Lance Compa finds widespread labor rights violations in the US, with employers frequently firing workers who try to form unions and millions excluded from organizing laws. The report highlights the need for US labor law reform to meet international human rights standards.
Researchers have developed a new technique called ICE that tests materials under extreme magnetic forces without explosions. The technique allows for faster and less expensive testing over a wide range of stress conditions.
Two studies reveal that half of parents using donor insemination are not telling their children about their biological origins, putting them at risk. Meanwhile, a UK study of adults conceived through DI found they faced identity issues, feelings of abandonment and deceit within their families.
A study at the University of California, Santa Barbara, detects a 'dead' time between photon emissions from a single quantum dot, verifying the quantum theory of light and paving the way for applications in quantum computing and optics. The experiment was performed at room temperature, a significant finding as it demonstrates the robus...
A preliminary study suggests that estrogen can effectively boost mood in women experiencing depression during perimenopause. The hormone significantly improved symptoms such as early morning awakening and loss of enjoyment, with relief achieved within three weeks.
A team of researchers found that radiologists prefer different images for evaluating various breast tissue abnormalities, requiring new computer programs for optimal results. The technology holds great promise in finding breast cancer earlier, but optimizing images for different tasks is crucial.
