Double disadvantage hurts more than twice as much

A new study from the Complexity Science Hub finds that belonging to more than one marginalized group can significantly harder forming social connections. The researchers developed a mathematical model and tested it using friendship data from around 40,000 U.S. high school students, revealing how overlapping disadvantages can interact.

Ageing stars may be destroying their closest planets

Astronomers at UCL and the University of Warwick discovered that aging stars are destroying giant planets orbiting closest to them. The researchers analyzed nearly half a million stars and found that planets were less likely to occur around stars that had expanded and cooled enough to be classed as red giants.

Study: Macrophage “bodyguard” disruptors could change breast cancer treatment by helping to overcome endocrine resistance

Researchers at University of Miami Miller School of Medicine have developed a new combination therapy that shrinks tumors, reduces cancer stem cells and reprograms immune environment to combat hormone-resistant breast cancer. The triple therapy approach targets tumor-associated macrophages, which act like bodyguards for cancer cells.

Built to heal, born to vanish: the promise of iron-manganese alloys in bone healing

Researchers have identified iron-manganese alloys as promising candidates for temporary bone fixation. These alloys combine strength, biocompatibility, and degradation properties, allowing them to support bone healing while degrading naturally. However, challenges remain, including controlling the release of manganese, which can pose t...

Are we ready for robot caregivers? The answer is a cautious “yes, if...”

A survey of 4,890 participants found that people are open to using home-care robots as long as they view them beneficially. Collaboration between users and developers is crucial for adoption, with emphasis on ethical considerations. Robots may play a significant role in addressing Japan's aging population and social healthcare challenges.

‘Forever’ chemicals found in B.C. sea otters

Researchers at the University of British Columbia have identified eight per- and polyfluoroalkyl substances (PFAS) in B.C. sea otters, with concentrations three times higher on average in otters near major cities and shipping routes. This proximity effect highlights the need for government regulation to prevent PFAS spread.

The law turns a “blind eye” to the severe financial consequences of being in an abusive relationship, study warns

A new study by the University of Exeter warns that the current laws turn a 'blind eye' to the long-lasting financial consequences of domestic abuse. The research suggests that the law should be reformed to take into account the financial impacts of abuse when dividing assets, enabling enhanced awards for victim-survivors.

California surface water costs triple during drought

A new University of California, Davis study finds that drought in California pushes the price of water from rivers, lakes, and reservoirs up by $487 per acre-foot, more than triple the cost during an average wet year. Managing groundwater and surface water together could keep water prices steady and support the state's economy.

Novel suppression strategy of mid-spatial-frequency error in sub-aperture polishing: Controllable spiral magnetorheological finishing

Researchers develop Controllable Spiral Magnetorheological Finishing (CSMRF) to eliminate mid-spatial-frequency ripple errors in sub-aperture polishing. This method integrates adaptive path spacing and spatially varying tool influence function, achieving effective control over targeted error distributions.

A path to safer painkillers – revealed by freezing opioids and their protein receptors in motion

A USC Dornsife team of scientists visualized how opioids like loperamide and naloxone engage a key brain receptor, revealing new avenues for developing painkillers. The study also showed that Narcan blocks the receptor by interrupting the signaling process, providing insight into designing longer-lasting or faster-acting antidotes.
