Nanotherapy effective in mice with multiple myeloma

Researchers have designed a nanoparticle-based therapy that effectively treats mice with multiple myeloma, a cancer of immune cells in the bone marrow. The nanoparticles carry a Myc inhibitor, which blocks a protein active in many types of cancer, and increase survival by 23 days compared to control groups.

Ultrasonic production of skimmed milk

Researchers successfully demonstrated cream separation from natural whole milk at liter-scales using ultrasonic standing waves, achieving fractionation outcomes desired for a particular dairy product. The technique allows for high volume throughputs of up to 30 liters per hour and can be used to specifically select milk fat globules of...

Sandia researchers first to measure thermoelectric behavior by 'Tinkertoy' materials

Researchers at Sandia National Laboratories have made the first measurements of thermoelectric behavior in a nanoporous metal-organic framework (MOF), a discovery that could lead to more efficient cooling and energy harvesting applications. The material, known as TCNQ@MOF, exhibits high Seebeck coefficient and low thermal conductivity.

New antibody insecticide targets malaria mosquito

Researchers have discovered a novel antibody insecticide that targets the African malaria mosquito, offering an alternative control strategy to halt the spread of the disease. The antibodies work by targeting a key component of the mosquito's nervous system, killing over 90% of infected insects within a day.

People tend to locate the self in the brain or the heart

A recent study published by Rice University researchers found that individuals generally prefer to locate their sense of self in the brain. This preference is stronger among those with an independent self-construal, who tend to assert autonomous goals and behaviors related to the brain. In contrast, people with an interdependent self-c...

New evidence links Arctic warming with severe weather

Research by University of Sheffield scientists links Arctic warming to extreme weather events in the UK and US, suggesting a connection between warmer Arctic temperatures and mid-latitude weather patterns. The study found increased variability in the jet stream and high pressure over Greenland, contributing to variable UK winters.

Mountain gorilla mamas sidestep having inbred offspring

In a study of mountain gorillas, researchers found that females avoid mating with their fathers to curb inbreeding. On average, seven out of ten offspring in groups with multiple males are sired by the dominant male, but none of his daughters' offspring

Stuttering linked to rhythm perception deficiency

Researchers at Michigan State University found that children who stutter have difficulty perceiving a beat in music-like rhythms, which may account for their halting speech patterns. This study has implications for treating stuttering and suggests that improving beat perception in children could lead to improved fluency in speech.

The life and death of beta cells

In a study published in ETH Zurich, researchers discovered that the microRNA-200 family triggers the death of beta cells, leading to type 2 diabetes. By blocking miR-200 production, scientists can guarantee the survival of these vital cells. This finding has significant implications for the development of new treatments for diabetes.

Study finds high prevalence of metabolic syndrome in US

A study published in JAMA Network found that nearly 35 percent of all U.S. adults and 50 percent of those 60 years or older had metabolic syndrome in 2011-2012. The condition is characterized by a combination of health conditions including obesity, high blood pressure, type 2 diabetes, and poor lipid profiles.
