FSU oceanographers present new conceptual framework to answer age-old question: What happens to carbon as it sinks through the ocean?

Researchers found upper ocean ecosystem conditions play a major role in shaping the composition of carbon-rich particles sinking into the deep ocean, storing carbon for decades. Microorganisms influence these transformations, which determine how long this carbon is locked away.

A slower-than-needed renewable energy transition could weaken the world’s motivation to cut carbon emissions, study warns

A new study suggests delaying renewable energy expansion may reduce global motivation to cut carbon emissions. The research finds that once global warming passes a critical threshold, the social cost of carbon suddenly falls, weakening the economic incentive to reduce emissions.

The ingenuity of white oval squid camouflage brought to light

The white oval squid employs a range of survival strategies, including color matching, disruptive patterns, and synchronized schooling. By analyzing the mathematical patterns behind their behavior, researchers have confirmed the effectiveness of these strategies in evading predators and camouflaging in diverse environments.

New study reveals how a common antibiotic disrupts nitrogen cycling and boosts greenhouse gas emissions in estuaries

A new study identifies how sulfamethoxazole, a common antibiotic, affects denitrification in estuarine sediments. The results show that the antibiotic disrupts the balance of nitrogen cycling processes, leading to increased nitrous oxide emissions and greenhouse gas warming.

Folklore sheds light on ancient Indian savannas

Researchers used medieval literary works to study vegetation in ancient Indian savannas, finding that they existed for at least 750 years. The study challenges the view that these areas are remnants of former forests and suggests that tree planting efforts may need to focus on different locations.

Why monkey studies may mislead research on cancer immunotherapy drugs targeting TIGIT

Researchers have discovered that rhesus macaques shed TIGIT from immune cell surfaces when exposed to plasmin, a natural enzyme involved in blood clot breakdown. This creates a soluble form of TIGIT that can still bind anti-TIGIT monoclonal antibodies, potentially leading to misleading safety and efficacy data for human trials.
