Jump rope aerodynamics

Researchers build robotic jump rope device to control rope parameters, capturing motion with high-speed cameras. They find that air-induced drag affects the shape of the rope, reducing total drag. Insights from the study may inform other situations involving flexible filaments in engineered and natural systems.

Should airplanes look like birds?

Researchers in California and South Africa re-designed an aircraft with a bird-inspired shape to improve aerodynamics and reduce fuel consumption. The study showed that a flying wing configuration can generate nearly wing-only levels of lift and drag, potentially making planes more energy efficient.

I2R Known-item-Search technology takes top honors at US standards annual TRECVID conference

The I2R team achieved high performance in both automatic and interactive search categories, showcasing the effectiveness of their Known-item-Search technology. With a mean inverted rank of 0.454 in automatic search and 0.727 in interactive search, they outperformed other teams and demonstrated the potential of their innovation.

COPD could be a problem with autoimmunity

Research suggests moderate to severe COPD may involve an auto-immune component, with 34% of patients having abnormal ANA and AT levels in their blood. The study found a significant association between these auto-antibodies and impairment of lung function.

Reading the signs: Plants and animals found common ground in response to microbial threats

Researchers have discovered that plants and animals share remarkably similar mechanisms to detect molecular signatures of infectious organisms, which could lead to new treatments for human diseases. The study's findings highlight the potential for inter-specific transfer of engineered receptors to confer resistance to various pathogens.

Designing more effective anti-HIV antibodies

Researchers at Boston Children's Hospital discovered that some HIV antibodies target the protein in its final form, making them ineffective. The team proposes designing immunogens to trap the protein in an intermediate state, preventing further structural rearrangements and blocking membrane fusion.

Professor Zvi Ram presents phase III recurrent glioblastoma survival and quality of life data from the first pivotal study of the NovoTTF-100A at 15th Annual Society for Neuro-Oncology Scientific Meeting

Phase III trial data suggests Tumor Treating Fields (TTF) therapy increases median survival time and improves quality of life scores compared to standard chemotherapy. Younger patients and those with better functional status show an impressive survival advantage.

Planet from another galaxy discovered

Astronomers have discovered a planet from another galaxy orbiting a star that has entered our Milky Way, providing the first confirmed detection of an extragalactic exoplanet. The planet, HIP 13044 b, was detected using high-resolution spectrograph FEROS attached to the MPG/ESO telescope at ESO's La Silla Observatory.
