Personalised treatment for stress-related diabetes

Researchers at Lund University have developed a personalized treatment for type 2 diabetes that targets the disease mechanism itself, rather than just its symptoms. The treatment, which uses a drug called Yohimbin, has shown promising results in improving insulin secretion in patients with the genetic risk variant.

More physical activity improved school performance

A study by the Sahlgrenska Academy found that two hours of extra physical activity per week can improve school performance in twelve-year-olds. The results showed a larger proportion of students from schools with extra physical activity achieved national learning goals in all subjects compared to control groups.

A canary for climate change

Researchers found a strong correlation between Northern Hemisphere seabird diversity and environmental stressors, with puffins and auks serving as indicator species. The study suggests that climate change has shaped the geographic distribution and population size of existing species over the past 5 million years.

What goes up must come down

Biologists at UC Riverside found that geckos reverse hind foot position to use the adhesive system as a brake and stabilizer when moving downhill. The study, published in Biology Letters, sheds light on gecko locomotion on non-level terrain and has applications in robotics.

Seniors run for the suburbs in their golden years

A Concordia University study found that seniors over 65 are more likely to move to suburbs than urban cores. This trend is driven by factors such as access to medical services and public transit infrastructure. As a result, researchers warn that this shift may have negative implications for seniors' quality of life.

Immune cells in the liver drive fatty liver disease and liver cancer

A team of scientists led by Prof. Mathias Heikenwälder found that immune cells, particularly CD8+ T cells and NK T cells, play a crucial role in the development of fatty liver disease, non-alcoholic steatohepatitis (NASH), and liver cancer. The study suggests that an existing metabolic imbalance triggers the activation and migration of...

New clues behind the resilience of a leading sexually transmitted pathogen, Chlamydia

Researchers have uncovered how chlamydia, a leading sexually transmitted pathogen, has evolved to evade its hosts through genomic shuffling and adaptation. The study found extensive genetic variation between chlamydia families, highlighting the importance of understanding this diversity for developing new therapeutics.

Frontline diagnosis and treatment of infant infections

A systematic review and meta-analysis found that frontline health workers can accurately diagnose bacterial infections in young infants, but access to antibiotics is limited. The study suggests that improving diagnosis and antibiotic access can help reduce neonatal deaths in low- and middle-income countries.

The Costco effect: Do consumers buy less variety at bigger stores?

A new study found that consumers purchase a greater variety of products when they are packaged individually rather than bundled together. Consumers tend to seek more options when choosing from single products, regardless of their preference. The study offers insight for retailers on how to influence consumer behavior and increase sales.

Are there enough fish to go around?

A study by researchers at the University of York found that domestic fish supplies have fallen to their lowest point in over 70 years, with only one fifth of recommended consumption levels met. The report also highlights the environmental costs of aquaculture and calls for sustainable production methods.

Autophagy helps fast track stem cell activation

Researchers found that autophagy, a cellular recycling mechanism, helps activate muscle stem cells by inducing metabolic shifts and coping with increased biosynthesis demands. Inhibited autophagy delayed stem cell activation, highlighting SIRT1's regulatory role in this process.

CWRU studies how women in recovery manage personal networks with family and friend users

A study by Case Western Reserve University's social work school found that many women in poverty struggle to drop users in their lives, making it difficult to establish new networks of non-using friends and supporters. The researchers identified relationships in the network as a key factor in whether women used drugs or not.

Slow enteral feeding protocol can reduce instances of death in extreme preterm infants

A standardized slow enteral feeding protocol significantly reduces necrotizing enterocolitis (NEC) and accompanying death in infants with extremely low birth weight. Infants on the slower protocol showed comparable weight gain, head growth, and NICU stay without increased mortality.

Defective gene renders diarrhea vaccine ineffective

A new study published in Clinical Infectious Diseases reveals that up to four out of ten children in Burkina Faso are genetically resistant to rotavirus strains found in existing vaccines. Children who cannot express the Lewis molecule, a sugar molecule needed as a receptor for the virus, do not become infected and therefore do not rec...

How the fruit fly could help us sniff out drugs and bombs

Researchers at University of Sussex have found that fruit flies can identify odours from illicit drugs and explosive substances as accurately as wine, a natural attractant. The study brings scientists closer to developing electronic noses (e-noses) that closely replicate the sensitive olfactory sense of animals.

Mars One -- and done?

A team of MIT researchers assessed the Mars One mission's technical feasibility, highlighting the need for new technologies to keep humans alive on Mars. The study found that a system to remove excess oxygen and more advanced water extraction methods are required, among other innovations.

Policies on marketing gifts to medical students

A cross-sectional study found that medical schools with stricter industry interaction policies had students report fewer gifts and interactions with marketing reps, suggesting these policies can reduce biases. The results suggest that limiting receipt of gifts should be a central feature of medical school regulations.

Country of origin: Are negative stereotypes always bad for business?

A new study shows that consumers won't judge products by their country of origin if the products are well-made. Consumers consider a country's reputation when evaluating its products, but this doesn't mean negative stereotypes always harm business. Instead, countries with poor reputations can promote superior product features to succeed
