Study explores why 'progressive teetotalers' may emerge from college engineering programs

A recent study by the University of Kansas researcher Margaret Kelley found that first-year engineering students who hold progressive attitudes, including those about gender equity, are more likely to drink less. The researchers argue that this behavior becomes in conjunction with their more progressive attitudes on women in the profes...

Engineering cellular function without living cells

Researchers at EPFL's LBNC have developed a quantitative, replicable method for studying gene expression using a cell-free system in combination with high-throughput microfluidic devices. This approach allows them to build synthetic biological logic gates that can be used to modify cellular functions and introduce new therapeutic purpo...

Traffic control of cells

Scientists have created a hydrogel matrix whose stiffness can be reversibly tuned using light, enabling the investigation of how cells respond to dynamic changes in their environment. The matrix has potential applications in cancer immunotherapy and understanding cell migration patterns.

Hearing loss before 50 may mean higher risk of drug and alcohol issues

A national study reveals that young and middle-aged adults with hearing loss are twice as likely to misused prescription opioids and other substances compared to their hearing peers. Health care providers may need to take special care when treating pain and mental health conditions in deaf and hard-of-hearing patients.

Can you 'catch' cancer?

Research suggests that parasitic worms cause majority of cancers in poor countries due to chronic inflammation and toxic egg excretions. However, some species of helminths, like the 'hyper tapeworm', inhibit cancer growth and may even enhance host's immune response to tumors.

How tree diversity affects invasive forest pests

A broad-scale study found a significant relationship between tree diversity and nonnative pest invasions. High tree diversity reduces pest invasions by creating ecological niches that make it harder for pests to find resources, while low diversity increases the risk of invasion. The study's results have important implications for fores...

How watching TV and movies helps people with attachment issues

Research suggests that people with attachment issues engage more with stories, such as movies and TV shows, to deal with relationship insecurities. They find a 'safe space' to understand their problems or imagine a functional relationship without real-life complications. This vicarious living can help them expand their social experiences.

Aspirin to fight an expensive global killer infection

Researchers at the Centenary Institute discovered that the tuberculosis bacterium hijacks platelets from the body's blood clotting system to weaken immune systems. Using anti-platelet drugs like aspirin, they were able to prevent hijacking and allow the body to control infection better.

Advanced imaging technology predicts cardiovascular risk from inflammation detected in arteries

Researchers used advanced PET/MRI technology to analyze inflammatory processes in arteries of individuals with atherosclerotic plaques. The study found that inflammation is present at early stages of atherosclerosis, particularly in regions without developed plaques.

Widely used malaria treatment to prevent malaria in pregnant women

The study found that the widely used antimalarial sulphadoxine-pyrimethamine (SP) is no longer effective in preventing malaria in areas with high levels of resistance. In areas where more than 37% of parasites carry six mutations, the effectiveness of SP appears to be fully compromised. The researchers are calling for further investiga...

Study questions value of genetic risk scores

A recent publication touted genetic risk scores as a tool for identifying patients at high risk of heart disease, cancer, and diabetes. However, a new study questions the value of these scores, finding they have lower accuracy when considering individual patient factors.

Phasing out air pollution emissions

A recent study suggests that rapidly phasing out air pollution emissions can prevent approximately 3.6 million avoidable deaths each year, while also increasing rainfall in drought-prone regions and limiting global warming. The researchers found that removing fossil fuel-related and all anthropogenic emissions could achieve the 2°C tar...

Earth's deep mantle flows dynamically

A new study reveals that the Earth's lower mantle is more dynamic than previously thought, with increased flow in regions where ancient ocean floors plunge into the planet's core. This discovery has significant implications for understanding how quickly Earth is cooling and the dynamic evolution of our planet.
