More for less in pastures

A nine-year study by R. Howard Skinner found that multispecies pastures produce significantly more forage than two-species mixtures, with an average increase of 31%. This improvement is attributed to the enhanced carbon storage in the soil, allowing it to hold more water and mitigate droughts.

Greener cities become more unjust

A European Union-funded study reveals that environmental amenities in cities often displace low-income residents, leading to increased housing costs and gentrification. The 'Greenlulus' project aims to develop a ranking of environmentally just cities and promote policies to mitigate the negative social impacts.

Putting software on a diet

Researchers aim to improve energy efficiency in software applications by increasing understanding of their impact on power usage. The three-year project will develop novel automatic analyses and tools to support decision-making, with the goal of enabling software engineers to create more energy-efficient code.

Breastfeeding alters maternal metabolism and protects against diabetes

A recent study found that breastfeeding for over three months postpartum alters maternal metabolism, producing lower concentrations of branched-chain amino acids and phospholipids. This change in metabolites is linked to reduced insulin resistance and a lower risk of developing type 2 diabetes.

Cancer stem cells in 'robbers cave' may explain poor prognosis for obese patients

Researchers discovered leukemia stem cells in fatty tissue of obese patients were more resistant to chemotherapy, using fatty acids as their energy source and actively signaling fat for lipolysis. This adaptation could help explain poorer outcomes in obese patients, potentially shedding light on new strategies to target cancer stem cells.

Gaining a better understanding of the way we taste

A team of Japanese researchers made a groundbreaking discovery about the way we taste by studying the structure changes of taste receptor proteins when they bind to taste substances. This change is thought to transmit information from outside the cell, enabling precise analysis of taste substance binding and related processes.

Study examines opioid agonist therapy use in Medicare patients

A recent study examined opioid agonist therapy (OAT) use among Medicare Part D beneficiaries. The analysis found that only approximately 81,000 patients received buprenorphine-naloxone therapy, despite an estimated 300,000 patients struggling with opioid use disorder and over 200,000 requiring hospitalization for opioid-related issues.

Single camera can capture high quality facial performance

A single camera can capture high-quality facial performance using a new method developed by Disney Research, which takes into account the underlying facial anatomy and skin thickness. This approach allows for robust and accurate tracking of facial expressions without requiring multiple cameras or extensive pre-computed facial motions.

Study finds differences in older adults who fall indoors versus outdoors

A new study by NYU's Steinhardt School of Culture, Education, and Human Development found that patients who fell indoors had more chronic health conditions and were less likely to recover at home, whereas outdoor fallers were younger and healthier. The findings can inform targeted initiatives to lower the risk of falls in older adults.

A chair for getting fit and trim

Researchers at Bielefeld University developed an active chair as part of the KogniHome project, which uses a virtual avatar to lead family members in fitness exercises. The chair measures physical parameters like respiration and heart rate while monitoring healthy posture.

Making parenting a national priority

A new National Academies of Sciences, Engineering and Medicine report calls for a national framework to uniformly expand access to best-in-class support programs for struggling parents. The report, co-authored by Eric Dearing, aims to provide a comprehensive approach to supporting parents of young children.

'Perfect storm' brought sea louse epidemic to BC salmon: University of Toronto study

A University of Toronto study found that high ocean temperatures and uncoordinated treatment likely led to an outbreak of sea lice in BC salmon farms. The study revealed that the spread of sea lice to migrating juvenile wild salmon resulted in the highest numbers of sea lice observed on wild salmon in a decade.

Surgeons' disclosures of clinical adverse events

Surgeons who avoid discussing preventability of adverse events or have difficult communication experiences are more negatively affected by disclosure. Surgeons with more negative attitudes about disclosure at baseline reported more anxiety about patients' surgical outcomes after disclosure.

Female birds call the shots in divorce

In a study of Purple-crowned Fairy-wrens, researchers found that females are more likely to initiate divorce due to dissatisfaction with their territory. Divorce allows females to gain better territories, which are crucial for reproductive success in this species.

Study shows changes in brain activity after mindfulness therapy in adolescents

Researchers found that mindfulness-based cognitive therapy increases activity in brain regions controlling emotional processing, leading to reduced anxiety in youth at risk of bipolar disorder. The study's pilot trial showed significant improvements in clinician-rated and youth-rated anxiety following 12 weeks of treatment.

Three new India projects to be launched

The University of Würzburg has launched three new projects in India, aiming to analyze European and Indian political thinking and develop literature in a globalized world. The projects also focus on adult education and lifelong learning, providing opportunities for students to study abroad and write their master theses.

Come on baby, (re)light my fire

Researchers found that couples who perceive their partner as responsive experience higher levels of desire, feeling special, and valuing their partner. Responsive partners convey the impression that they are worth pursuing, promoting an already valuable relationship.
