New evidence of an unrecognized visual process

Researchers discovered evidence of visual ambiguity and rivalry in an unrecognized reference frame, challenging the understanding of how our brains process visual information. The study found that object-frame rivalry is a competing process to spatial rivalry, with similar brain regions and processes involved.

Seeing brands as people

New research reveals that brands perceived as partners elicit cooperative behavior, while those viewed as servants prompt competitive actions. Participants' responses were influenced by automatic social behaviors, revealing a complex relationship between cognition and consumer culture.

GQ GMC-500Plus Geiger Counter

GQ GMC-500Plus Geiger Counter logs beta, gamma, and X-ray levels for environmental monitoring, training labs, and safety demonstrations.

JCI online early table of contents: Dec. 1, 2011

Researchers found that dental pulp stem cells can repair spinal cord injuries in rats, promoting hind limb function and nerve regeneration. A new vaccine combination boosted BCG's effectiveness against tuberculosis by reducing clinical disease and preventing reactivation of latent infection.

New research project to examine the trans-Atlantic slave trade

The EUROTAST project brings together young researchers to study the transatlantic slave trade's history and impact. The four-year project will explore captives' origins in Africa and physical quality of life, with a focus on interdisciplinary research and public dissemination.

Celestron NexStar 8SE Computerized Telescope

Celestron NexStar 8SE Computerized Telescope combines portable Schmidt-Cassegrain optics with GoTo pointing for outreach nights and field campaigns.

Christmas burst reveals neutron star collision

A neutron star spiraling into its companion star caused a unique gamma-ray burst with varying wavelengths and characteristic radii. The Helium Merger Model, developed in 1998, explained the unusual properties of the burst, which may be part of a new class of bursts.

Manchester jet engine project takes FLITES

The Manchester FLITES project aims to produce first-ever images of chemical species in aero-engine exhaust plumes using novel fibre lasers. The four-year study will focus on lowering carbon dioxide emissions, enhancing turbine-related research and development capacity.

Not all cellular reprogramming is created equal

A study published in Cell Stem Cell reveals that adjusting the levels of reprogramming factors can significantly impact the quality and fidelity of induced pluripotent stem (iPS) cells. This finding explains the variability in iPS cell quality reported in recent studies, which has sparked debate about their therapeutic potential.

Fluke 87V Industrial Digital Multimeter

Fluke 87V Industrial Digital Multimeter is a trusted meter for precise measurements during instrument integration, repairs, and field diagnostics.

Repairing spinal cord injury with dental pulp stem cells

Researchers found that dental pulp stem cells can inhibit nerve cell death, promote nerve regeneration, and replace lost support cells in rats with severe spinal cord injuries. The study aims to translate this approach into an effective treatment for severe spinal cord injury.

Newly discovered heart stem cells make muscle and bone

Researchers have identified a new pool of stem cells in the heart with long-term expansion capacity and ability to form various cell types, including muscle, bone, and neural cells. This discovery may lay the foundation for regenerative therapies to enhance tissue repair in the heart.
