Bats split on family living

Researchers found a unique social structure in a small town where males and females coexist in the same roosts. This arrangement allows females to conserve energy and ensures faster growth of their young. In contrast, lowland areas have female-only childrearing colonies.

Greenland ice cores provide vision of the future

A new study using a 2,540-metre long Greenland ice core has reconstructed the island's temperature and ice sheet extent during the last interglacial period, known as the Eemian period. The research found that the warmest temperatures were about 8°C degrees warmer than average over the past 1,000 years.

Household chores: Gender equality's final frontier

A new study by Cornell University sociologist Sharon Sassler found that cohabiting women tend to take on a disproportionate share of household chores, even when the women work and the men don't. Despite expecting more equal partnerships, most women retain accountability for the performance of their partners' chores.

Putting the squeeze on cells

Researchers at MIT have created a device that can deliver RNA, proteins and nanoparticles through cell membranes by deforming cells. The technique has shown success in delivering reprogramming proteins and generating induced pluripotent stem cells with improved efficiency compared to existing methods.

Hailstones reveal life in a storm cloud

Researchers found a rich diversity of microbial life and chemicals in hailstones from a storm cloud, suggesting specific processes during cloud lifetime impact bacterial distribution. The study suggests that these processes could affect long-distance transport and geographical distribution of microbes on Earth.

Immigrants: Highly educated, underpaid

Recent immigrants to Canada often over-qualified for their jobs due to language barriers and lack of work experience. However, increased proficiency in English or French, combined with post-immigration education and training, can significantly improve job matching.

Novel approaches needed to end growing scourge of 'superbugs'

Infectious disease experts call for novel approaches to end the growing scourge of 'superbugs,' citing 2 million annual infections and 100,000 deaths. The authors recommend new strategies to prevent infections, encourage economic investment in anti-infective treatments, and alter host-microbe interactions.

Nanoparticles digging the world's smallest tunnels

Scientists at KIT and Rice University successfully dug the world's smallest tunnels into graphite samples, opening doors to structuring of materials on a nanometer scale. The creation of porous graphite with tailored pore sizes could enhance lithium-ion battery performance and enable long-term drug delivery in medicine.

Frequent multitaskers are bad at it

A University of Utah study found that people who multitask the most, including those talking on cell phones while driving, are actually least capable of doing so. This is because they often lack the ability to focus attention on a singular task and tend to be impulsive and sensation-seeking.
