New research shows when animals are fed a diet high in saturated fat for nine weeks, their gut bacteria change in ways that influence brain chemicals and fuel anxiety.
Direct evidence found for dairy consumption in the Pyrenees in the earliest stages of the Neolithic
A study on the remains of the Chaves and Puyascada caves, both located in the province of Huesca, Spain, yields the first direct proof of the consumption and processing of dairy products in the Pyrenees already at the start of the Neolithic period, approximately 7,500 years ago, as well as...
Wear it, then recycle: Designers make dissolvable textiles from gelatin
Researchers hope their DIY machine will help designers around the world experiment with making their own, sustainable fashion and other textiles from a range of natural ingredients -- maybe even the chitin in crab shells or agar-agar from algae.
Gonadal function in male mice disrupted by prenatal risk factors
Researchers have consistently shown that prenatal exposure to Di (2-ethyhexyl) phthalate harms the reproductive system in male mice and causes fertility defects. In a new study, scientists have shown that the combination of DEHP and a high-fat diet in pregnant mice can cause more damage to pups than each factor...
Vitamin B6: New compound delays degradation
A low vitamin B6 level has negative effects on brain performance. A research team has now found a way to delay the degradation of the vitamin.
A new weapon in the battle against antibiotic resistance: Temperature
Scientists have shown in laboratory experiments that an increase in temperature from 37 to 40 degrees Celsius increased the resistance rate for two antimicrobials, while for a third antimicrobial, the higher temperature reduced the resistance rate. If these results can be replicated in human patients, fever control could be a...
Quantum entanglement measures Earth rotation
Researchers carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work represents a significant achievement that pushes the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further exploration at the intersection between quantum mechanics and...
Fasting primes the immune system’s natural killer cells to better fight cancer, new study in mice finds
A team of researchers has shown for the first time that fasting can reprogram the metabolism of natural killer cells, helping them to survive in the harsh environment in and around tumors, while also improving their cancer-fighting ability.
Infectious H5N1 influenza virus in raw milk rapidly declines with heat treatment
The amount of infectious H5N1 influenza viruses in raw milk rapidly declined with heat treatment in laboratory research. However, small, detectable amounts of infectious virus remained in raw milk samples with high virus levels when treated at 72 degrees Celsius (161.6 degrees Fahrenheit) for 15 seconds -- one of the...
Sharks have depleted functional diversity compared to the last 66 million years
New research has found that sharks retained high levels of functional diversity for most of the last 66 million years, before steadily declining over the last 10 million years to its lowest value in the present day.
