Nanoparticles aid bone growth

A new study has shown that adding nanoparticles to porous materials can lead to denser bone tissue. Researchers found that the nanoparticles increased bone ingrowth by threefold after 12 weeks compared to a biodegradable plastic scaffold alone. The study paves the way for further research into tissue engineering and bone regeneration.

Worldwide mission to solve iron deficiency

A global mission to address iron deficiency is underway with a focus on increasing iron content in cereal grains like rice and wheat. Dr Alex Johnson's project aims to improve iron delivery from leaves to seeds, benefiting developing countries where iron deficiency affects 30% of the world's population.

Cartilage regeneration '20,000 Leagues Under the Sea'

Bioengineers at Rice University have developed a method to stimulate cartilage cell growth using intense pressure, resulting in tissue with nearly all properties of natural cartilage. The new process has potential for treating arthritis and repairing damaged tissues, but further testing is needed.

Nanoparticles assemble by millions to encase oil drops

Researchers at Rice University create nanoscale 'baton'-like particles that spontaneously assemble into bag-like sacs around oil droplets in water. This phenomenon could lead to innovative technologies for cleaning up oil spills and polluted groundwater, as well as delivering drugs with controlled release.

Why did the EPA fire a respected toxicologist?

The EPA dismissed Deborah Rice, a highly respected toxicologist, after the chemical industry complained about her views on deca's health hazards. Herbert Needleman argues that this trend is not new and unique, citing his own dismissal for speaking out on lead poisoning.

UD researchers discover novel 'gene toggles' in world's top food crop

University of Delaware researchers have discovered a new type of molecule called natural antisense microRNAs (nat-miRNAs) that can turn off genes in rice, which is the primary source of food for half the world's population. These novel molecules may help scientists locate similar gene regulators in other organisms, including humans.

Less can be more, for plant breeders too

Researchers have developed a tool to rapidly silence specific genes in rice, enabling faster breeding and improved crop performance. This breakthrough uses artificial miRNAs to target and disable genes of interest, with potential applications in hybrid seed production and enhanced resistance to pathogens and insects.

Feds fund study of drug that may prevent radiation injury

A new study funded by the Defense Department aims to develop a drug based on carbon nanotubes to prevent acute radiation injury deaths. The experimental drug, Nanovector Trojan Horses (NTH), has shown promising results in preliminary tests, with mice showing enhanced protection when given first-generation NTH drugs prior to exposure.

Proteins pack tighter in crowded native state

A new study from Rice University and the University of Houston found that proteins pack more tightly in their natural environment, with increased structural content and stability. The research suggests that protein structure is affected by crowding, even when proteins are in their folded state.
