A second planet in the Beta Pictoris system

A team of astronomers has discovered a second giant planet, β Pictoris c, in the Beta Pictoris system. The exoplanet has a mass nine times that of Jupiter and completes its orbit in approximately 1,200 days. This detection marks the first time a planet has been found around a star like β Pictoris using the radial velocity method.

Are attitudes contagious?

A Northwestern University study found that people acquire attitudes toward individuals based on nonverbal signals, including implicit biases. The researchers discovered that participants attributed their negative attitudes to the target's behavior rather than the observer's actions, highlighting the importance of considering the role o...

Blocking inflammatory pathway key to preventing brain metastasis from melanoma

Researchers at Tel Aviv University discovered that tumor cells 'hijack' an inflammatory pathway in the brain to spread melanoma, and blocking this pathway could prevent brain metastases. The study found that inhibiting the expression of a specific receptor on melanoma cells significantly inhibited the development of brain metastases.

ACP releases paper on methods for managing conflicts of interests in clinical guidelines

The American College of Physicians (ACP) has developed a rigorous process for disclosing interests and managing conflicts of interest to ensure transparency, proportionality, and consistency in clinical guideline development. The process applies to all individuals involved in ACP's clinical guidelines and guidance statements.

These migratory birds will risk their lives for a good nap

Researchers found that migratory songbirds sleep differently depending on their condition, trading off safety for lower energy expenditure. Birds in poor condition sleep with their head tucked in, while those in good condition keep their head facing forward, exposing them to a higher predation risk.

University of Michigan study indicates negative outcomes for Native American children who are spanked

A new University of Michigan study found that spanking is harmful for all three racial groups, despite cultural differences. Spanking at age 1 predicts child behavior issues at age 3, leading to more spanking at age 5. The study's findings highlight the need for discipline alternatives to spanking in Native American communities.
