Light-powered 3-D printer creates terahertz lens

The new lens uses metamaterials and 3D printing to counter the intrinsic imperfections of typical lenses, enabling flawless images without additional corrective components. The technology has potential applications in biomedical research and security imaging, making terahertz imaging cheaper, higher resolution, and more available.

What lies beneath West Antarctica?

Scientists have uncovered a wetland-like environment beneath the West Antarctic Ice Sheet, where Subglacial Lake Whillans is fed by melting ice and small amounts of seawater. The findings provide unique insights into the biogeochemistry and geophysics of subglacial lake systems, which are essential for understanding global sea-level rise.

Save urban bees

A new project aims to mobilize the public to help local urban bees by planting bee-friendly flowers and tracking their movements. The London Pollinator Project encourages Londoners to plant flowers that are rich in nectar and pollen, such as English lavender and spiked speedwell, to support the ailing urban bee population.

Salt-inducible kinases may have therapeutic potential for autoimmune diseases

Research suggests that salt-inducible kinases may have therapeutic potential for autoimmune diseases. By inhibiting these enzymes, scientists were able to limit the production of inflammatory molecules by certain types of human immune cells, increasing levels of anti-inflammatory IL-10 and reducing proinflammatory cytokines.

Harsh out of necessity

In a study, MS patients showed more severe moral judgments than average, even in neutral conditions, attributing negative emotions to external causes. This 'externally oriented thinking' helps them minimize damage but also leads to an inability to reflect on emotions and identify real causes of their negative emotional state.

Rare disease gene has a key role in chronic hepatitis C infection

A recent study published in PLOS Pathogens identifies a host gene involved in the formation of Hepatitis C virus particles. The gene, ABHD5, regulates the efficiency of virus assembly and release from human host cells. High levels of ABHD5 expression lead to fewer lipid droplets, while lower levels result in their accumulation.

Stem cells know how to open up and unwind

Research found that heterochromatin organisation in embryonic stem cells is maintained in an open form through the action of key stem cell factors. This open architecture may contribute to keeping stem cells unspecialised and full of developmental potential.

Want to eat better? Sorry, we're closed

Research from Ohio State University found that stores in low-income areas are often closed too early, limiting access to healthy food options. The study suggests that extended store hours and transportation services could help meet consumers' needs.

Gene therapy halts pulmonary hypertension progression in large animal pre-clinical study

Scientists used gene therapy to halt pulmonary hypertension progression in a large animal model. The approach delivered SERCA2a gene via aerosol inhalation, slowing vascular changes and improving heart function. Further studies are needed to assess long-term efficacy and safety before human clinical trials.

Are we alone? Setting some limits to our uniqueness

A new paper uses exoplanet discoveries to estimate the probability of advanced life evolving on habitable planets. The authors find that unless the odds are extremely low, humanity is likely not the universe's first technological civilization. They calculate a 'pessimism line' below which human uniqueness would be impossible.

Underwater archaeology looks at atomic relic of the Cold War

The article discusses the recent declassification of documents on the USS Independence, a World War II aircraft carrier used as a target in the first atomic bomb tests. The documents provide insight into the ship's post-Bikini history, including radiation levels and decisions to remove contaminated fuel oil.

Why fraternal twins run in families

Researchers identified two genes associated with twinning, including one linked to higher levels of FSH that may lead to multiple eggs being released at once. The findings have implications for infertility treatments and may help predict how women respond to fertility treatments.

Ocean views linked to better mental health

A study by Michigan State University found that residents with ocean views experience significantly lower levels of psychological distress compared to those with green space. The researchers suggest that blue spaces may have a calming effect on the mind, while human-made areas in green spaces may not.
