HKU biologist reveals important role cities play in conservation of threatened species

A recent study finds that urban centers like Hong Kong can play a crucial role in conserving globally threatened species. Introduced populations of these species have been thriving outside their native habitats, providing an opportunity to augment declining populations in their native ranges and mitigate threats to local ecosystems.

Women as decorative accessories: Keep silent or take a stance?

A recent study published in Springer's journal Sex Roles found that awareness campaigns targeting women can be a powerful tool to encourage collective action against female sexual objectification. The research revealed that watching a critique video clip increased women's willingness to support protests, whereas men showed no such effect.

Global warming hiatus disproved -- again

A new study using independent data from satellites and robotic floats confirms that the oceans have warmed at a rate of 0.12 degrees Celsius per decade since 2000, nearly twice as fast as earlier estimates. This finding eliminates much of the global warming hiatus, which was attributed to biases in ship measurements.

Study confirms steady warming of oceans for past 75 years

A new study confirms the steady warming of oceans over the past 75 years, with a rate of 0.12 degrees Celsius per decade since 1997, contradicting claims of a global warming 'hiatus'. The research uses data from buoys, satellites, and Argo floats to support the NOAA findings, providing accurate measurements of ocean temperatures.

Study: Medicaid expansion boosts Michigan's economy and will more than pay for itself

A new study found that Michigan's Medicaid expansion has boosted the state's economy and budget, generating over $2.3 billion in personal spending power each year. The program is expected to continue having a self-paying effect for at least five years, with the state ending up with more money than it spends.

Not feeling the music

Researchers found that individuals with specific musical anhedonia showed reduced connectivity between auditory processing and the Nucleus Accumbens, a key reward structure. In contrast, those with high music sensitivity demonstrated enhanced connectivity, highlighting different pathways to reward for music and other stimuli.

What do Google search queries reveal about brand attitudes?

Researchers found that users who are actively shopping in a category are more likely to search for any brand, but as users move from recognition to purchase intent, they become increasingly more likely to search for the specific brand. Brand owners are also more likely to search for their brand, even when not actively shopping.

Review examines diversity in dermatology clinical trials

A review of dermatology clinical trials found that racial and ethnic groups are underrepresented among study participants, with most being white. The lack of diversity is attributed to inadequate reporting of ethnicity and race, which may lead to a more homogenous population. To address this issue, the review suggests prioritizing raci...

York U research identifies icy ridges on Pluto

A team of researchers from York University, NASA, and Johns Hopkins University have identified icy features on Pluto, including penitentes, which are bowl-shaped depressions with spires around the edge. The study suggests that these features may exist on other planets where environmental conditions are similar.
