Is punishment as effective as we think?

A social dilemma experiment found that punishment is ineffective in promoting cooperation among players, with players instead replacing defection with punishment. The study suggests that punishment has a demoralizing effect and reduces the incentive to choose cooperation over competition.

Bacteria acquire resistance from competitors

Researchers have discovered that bacteria can inject toxic proteins into their competitors, causing cell lysis and death, and then acquire antibiotic resistance by incorporating the released genetic material. This ability allows bacteria to rapidly develop resistance to antibiotics, posing a significant threat to patients in hospitals.

Conserving coral communities

A recent study led by Harvard University researchers found that coral restoration efforts can have a positive impact on fish communities in the short term and over time. The study showed that even after just one week, significantly more fish and a greater diversity of species were present at experimental coral beds.

New model considers an extra factor to improve our prediction of nuclear fission

Researchers at Tokyo Tech have developed a new Langevin model that predicts low-energy fission more accurately by accounting for the deformation of nuclear fragments. The four-dimensional model fits empirical data better than previous models and has potential applications in radioactive waste containment and nuclear power generation.
