A Venus flytrap for nuclear waste

Researchers at Northwestern University have developed a new material that permanently traps only the desired radioactive ion, cesium, from a sodium-heavy solution. The synthetic material, made from layers of a gallium, sulfur and antimony compound, sequesters 100% of the cesium ions while ignoring all the sodium ions.

MU researcher uses bacteria to make radioactive metals inert

A Missouri University researcher is studying sulfate-reducing bacteria that can convert toxic uranium into nearly insoluble uraninite, reducing contamination and environmental costs. The bacteria's ability to cleanse water is being explored, with potential applications for heavy metal pollution from storage tanks and industrial waste.

Using waste to recover waste uranium

Scientists have recovered uranium from polluted waters using bacteria and inositol phosphate, a cheap waste material. The process is economically viable, especially as the world price of uranium is likely to increase, offering an environmental protection benefit.

Bringing harmony to electronic waste disposal

The global e-waste problem requires harmonization of disposal and recycling standards across national borders to effectively address the issue. The use of outdated electronic devices poses significant risks to human health and the environment, with 20-50 million tonnes of e-waste generated annually.

New treatment in sight for ovarian cancer

Researchers at the University of Gothenburg have developed a new treatment that uses a radioactive substance to seek and destroy tumour cells in ovarian cancer patients. The treatment, which has shown no unwanted side-effects in an initial study, aims to provide a more effective alternative to current treatments.

Waste not, want not

Researchers in Japan investigate three technologies for heat recovery: latent heat, reaction heat, and thermoelectric devices. They find that high-temperature waste heat with adequate exergy value exists in many industries, offering effective ways to recover waste heat.

New use for human hair

A recent study found that adding human hair waste cubes to commercial growth medium can increase plant yields relative to untreated controls. However, results showed lower yields compared to inorganic fertilizers, suggesting hair waste should not be used as a single source for fast-growing crops like lettuce.

Strange travels

Research focuses on transport phenomena in heterogeneous media, exploring anomalous transport and its role in hydrogeology. The study highlights the importance of concentration tails in assessing radioactive waste disposal reliability.

Technological breakthrough in the fight to cut greenhouse gases

Scientists at Newcastle University have developed a highly energy-efficient technology to convert waste carbon dioxide (CO2) into cyclic carbonates, which can be used in various industrial applications. The technology has the potential to use up to 48 million tonnes of waste CO2 per year, reducing UK emissions by about four percent.

New material can find a needle in a nuclear waste haystack

A team of Northwestern University chemists has developed a new metal sulfide material, KMS-1, that can effectively remove strontium, a major component of nuclear waste, by exploiting its unique properties. The material works across the pH scale and outperforms existing methods in terms of selectivity and efficiency.

Combined radiation seed, chemotherapy wafer implants show promise in treating cancerous brain tumors

A study published in the Journal of Neurosurgery found that simultaneous implantation of radioactive seeds and chemotherapy wafers following surgery improved patient survival rates for recurrent glioblastoma multiforme (GBM) patients. The median survival was 69 weeks, with nearly a quarter of patients surviving two years.

Paying peanuts for clean water

Researchers have found that peanut husks can extract up to 95% of copper ions from waste water, while pine sawdust achieves only 44% extraction. The process works best at slightly acidic conditions, making it a promising solution for reducing toxic copper levels in natural resources

New cancer weapon: nuclear nanocapsules

Researchers at Rice University have developed a way to package radioactive particles inside DNA-sized carbon tubes to target tiny tumors. The alpha-emitting nanocapsules are designed to deliver a single, direct hit to cancer cells, making them potentially more effective than traditional beta-particle radiation.

A sound way to turn heat into electricity

Researchers have developed small acoustic heat-engine devices that convert waste heat into sound and then into electricity. The technology shows promise for harnessing solar energy and cooling electronics, with plans to test the devices within a year at military radar facilities and universities.

A galactic fossil

Astronomers have measured the age of a star in our Galaxy using ESO's VLT, finding it to be 13.2 billion years old, nearly as old as the Universe itself. This discovery was made possible by a new technique that combines radioactive elements thorium and uranium to accurately determine a star's age.
