Trigger for past rapid sea level rise discovered

Researchers at the University of Bristol used climate and ice sheet models to identify the cause of rapid sea level rise in the past. They found that a process called 'saddle-collapse' led to two major events, including the 14,600-year-old Meltwater pulse 1a event, which resulted in a 9m sea level rise.

Smart Materials get SMARTer

Researchers at University of Pittsburgh and Harvard University created self-regulating microscopic materials that can continuously sense and regulate temperature. The new material, called SMARTS, offers a customizable way to trigger chemical reactions on cue and reproduce stable feedback loops found in biological systems.

It's not just lunch

A study published in PLOS ONE found that sharing a meal with a former romantic partner is more likely to make the current partner jealous than other activities. The researchers also found no significant differences in jealousy reported by male and female participants.

Mayo Clinic finds switch that lets early lung cancer grow unchecked

Researchers at Mayo Clinic found that early-stage lung cancer cells use a biological process called epithelial-mesenchymal transition (EMT) to bypass growth controls and enable uncontrolled growth. This discovery offers new clues for a potential approach to treating lung and possibly other cancers as early as possible.

Want to get teens interested in math and science? Target their parents

A new study published in Psychological Science found that parental involvement can significantly increase the number of students enrolled in STEM courses. The intervention involved sending parents glossy brochures and a dedicated website to promote STEM education, resulting in more advanced math and science classes taken by participati...

Smart materials get SMARTer

Scientists develop SMARTS, a customizable platform for autonomously regulating chemical reactions and temperature, mimicking biological systems. The material's dynamic feedback loops enable it to sense and modulate desired stimuli without external power, paving the way for intelligent medical implants and efficient buildings.

Strong communication between brain and muscle requires both having the protein LRP4

Research finds that both brain and muscle cells require the protein LRP4 to ensure robust communication. Without it, communication is inefficient and short-lived, contributing to disabling disorders like myasthenia gravis. The study suggests that delivering LRP4 through gene therapy may help bolster insufficient levels in patients.

Ions, not particles, make silver toxic to bacteria

Researchers found that silver nanoparticles are less toxic to bacteria than their released ions. The team's study suggests that controlling the rate of ion release can enhance antibacterial properties and mitigate environmental impacts. They also discovered hormesis, where low doses of silver ions stimulate bacterial growth.
