Researchers compare nutritional value of infant and toddler foods

A recent study published in Nutrition Today found that infant and toddler foods in pouches tend to have higher sugar content and fewer single-vegetable products compared to jarred or tray-packaged options. This highlights the need for caregivers to be aware of the nutritional profiles of these popular convenience foods.

Penguin responses to climate change and human activity

This study examines how penguin species in Antarctica respond to changes in krill availability due to human activities and climate change. The analysis of nitrogen stable isotope values reveals that gentoo penguins shift their diet towards fish and squid, while chinstrap penguins remain exclusive to krill.

CalDigit TS4 Thunderbolt 4 Dock

CalDigit TS4 Thunderbolt 4 Dock simplifies serious desks with 18 ports for high-speed storage, monitors, and instruments across Mac and PC setups.

Click, click, cook: Online grocery shopping leaves 'food deserts' behind

A Yale University analysis found that online grocery delivery systems cover 90% of food deserts, increasing access to nutritious food for low-income communities. The study suggests that online shopping can reduce obesity and improve health outcomes by providing essential nutrients and promoting better eating habits.

Cell-free synthetic biology comes of age

Researchers have made significant breakthroughs in cell-free gene expression, enabling high-yielding protein synthesis and expanding genetically encoded chemistry. This has opened doors to create new types of enzymes, materials, and therapeutics. Northwestern University's Center for Synthetic Biology is at the forefront of this field.

Scientists build a 'Hubble Space Telescope' to study multiple genome sequences

Researchers have developed a new tool that can analyze 1.4 million genetic sequences simultaneously, allowing them to study species relationships on a larger scale than before. This technology has the potential to reconstruct how life has evolved over hundreds of millions of years and unlock secrets about the code of life.

Effects of Justinianic Plague

The study challenges scholarly consensus on the Justinianic Plague's effects, finding no detectable decrease in economic vitality or demographic decline. Historical texts exaggerate plague mortality, and burial customs remained unchanged despite the outbreak.

AmScope B120C-5M Compound Microscope

AmScope B120C-5M Compound Microscope supports teaching labs and QA checks with LED illumination, mechanical stage, and included 5MP camera.

Family support reduces chance of school and workplace bullying

A study by Anglia Ruskin University found that LGB students with supportive families had a significantly lower chance of being bullied at school and in the workplace. The researchers discovered that family support reduced bullying by 31% for gay and bisexual men and 25.6% for lesbian or bisexual women during school age.

2D materials boost carrier multiplication

Researchers at the Institute for Basic Science discovered a carrier multiplication process in 2D semiconductors that could improve the efficiency of solar cells. The phenomenon is more efficient in 2D materials than in bulk semiconductors and has the potential to increase the maximum power conversion efficiency up to 46%

Why stress doesn't always cause depression

Researchers found that rats susceptible to depression had more serotonin neurons after chronic stress, but these effects could be reversed through amygdala activation. In contrast, resilient rats showed no significant change in serotonin levels under stressful conditions.

Justinianic plague not a landmark pandemic?

A recent study by researchers at SESYNC found no concrete evidence to attribute the effects of the Justinianic Plague to the pandemic. The team examined diverse datasets, including written sources, inscriptions, and pollen samples, but found that trends continued without change before and after the plague outbreak.

SAMSUNG T9 Portable SSD 2TB transfers large imagery and model outputs quickly between field laptops, lab workstations, and secure archives.

Breathing? Thank volcanoes, tectonics and bacteria

A new study suggests that volcanic eruptions triggered by tectonics led to the Great Oxidation Event, a significant increase in oxygen in Earth's atmosphere about 2.5 billion years ago. The research proposes that this event was also linked to a change in the composition of carbon isotopes in carbonate rock record.
