Why certain fish are left off the hook

A recent study finds that most US fish stocks are not constrained by the Magnuson-Stevens Act, but rather by economic demand and other factors. The act's critics may be misinterpreting the data, as healthy stocks are being left in the water due to market forces and policies.

Masters of acclimation: Octopuses adjust to cold by editing their RNA

Researchers have discovered that octopuses and cephalopods use RNA editing to rapidly respond to environmental temperature changes. By tweaking their protein function, these animals can acclimate to cold water, but not rapid changes. The study reveals a unique mechanism of genetic adaptation in these species.

Seaweed farming may help tackle global food insecurity

Research suggests that seaweed farming could be a game-changer for addressing food insecurity globally. By reducing the need for land, freshwater, and chemical fertilizers, seaweed cultivation can lead to higher incomes for farmers in coastal regions of Africa and Southeast Asia. As demand for nutrient-rich seaweed products grows world...

Elusive planets play “hide and seek” with CHEOPS

The CHEOPS satellite has successfully detected two elusive exoplanets, TOI 5678 b and HIP 9618 c, using its precise measurements. The planets have sizes similar to Neptune and Earth radii, respectively, with orbital periods of 48 days and 52.5 days.

Study uncovers how B cells react to skin cancer

A new study reveals that antibody-producing B cells in patients with melanoma may be defective, leading to ineffective responses against the disease. The research finds that active B cells accumulate at the edge of tumors and gather in small groups, carrying specific antibody features that react with T cells and other immune cells.

The study used computational genetic tools to analyze over 235,000 genetic variants likely to have originated from Neanderthals.

Colorful foods improve athletes’ vision

Researchers at the University of Georgia found that a diet rich in colorful fruits and vegetables can improve athletes' visual range by acting as a filter to prevent blue light exposure. This improvement can lead to better eye health and functional vision, essential for top athletes in almost any sport.

CARD8 helps human immune system respond to some viruses, including COVID-19

A study published in PLOS Biology found that the CARD8 inflammasome sensor is essential for detecting coronavirus infections, but may detect different viruses in different people.
