A Zen discovery: Unrusted iron in ocean

A team of scientists has made a groundbreaking discovery that challenges the long-held assumption about oceanic iron cycles. They found that organic compounds can capture some iron spewed by hydrothermal vents, enabling it to be carried away in seawater and reaching the surface, where it can nourish marine life more efficiently.

Eating less may not extend life

A new study found that caloric restriction does not extend the life of lean mice, contradicting previous findings. Obese mice, however, benefited from caloric restriction, suggesting it may be a useful strategy for weight loss. The researchers propose that energy expenditure and intake should be in balance.

Real-time gene monitoring developed

Researchers from USC and Cambridge have developed a method to track the activity of specific genes in real-time using a specially modified camera and computer vision techniques. This breakthrough has potential applications in various fields, including military, retail, and entertainment.

Where there's wildfire smoke, there's toxicity

A new study analyzing particulate matter from Southern California wildfires confirms that the composition of smoke posed more serious potential threats to health than is generally realized. The study found that fire emissions produce a significantly larger aerosol in size, making it easier for particles to penetrate indoor structures.

USC: gamers play against type

A USC survey of 7,000 EverQuest II players found that older players were more typical, with playing time increasing with age. Women logged more hours in the game and were less likely to quit, while also exercising regularly. The study suggests that online gaming may not compromise mental health, contrary to stereotypes.

Catalyst mystery unlocked

A team of researchers has developed a computational model that challenges entrenched ideas about enzyme catalysis, proposing a method for designing custom-designed enzymes. The 'lock and key' model is replaced by an electrical attraction theory, suggesting a perfect physical fit between catalyst and substrate is not necessary.

Mutant testis cells behind genetic disorder have survival advantage

A new study found that mutant testis cells carrying the Apert's syndrome mutation have a selective advantage over non-mutant cells, leading to an exponential increase in sperm from older men containing the mutation. This explains why children born from sperm of older fathers are more likely to inherit genetic disorders.
