The seat of meta-consciousness in the brain

Researchers have identified a specific cortical network in the brain that becomes active when lucid dreamers become aware of their dreaming state. This network, including the right dorsolateral prefrontal cortex and frontopolar regions, is associated with self-reflective functions and has been linked to consciousness development.

Computers can predict effects of HIV policies

A computer program calibrated to model accurately HIV spread in NYC predicts significant reduction in infection rate with comprehensive intervention strategies. The model simulates individual behavior and transmission networks, providing detailed examination of how interventions affect the epidemic.

'Diving board' sensors key to DNA detection

Researchers at Drexel University have developed a sensor technology that can detect DNA in liquid samples, allowing for quick identification of harmful cells and bacteria. The 'diving board' sensors use electric current to measure the vibration frequency of a cantilever, enabling sensitive and timely tests.

The Olympics and bare feet: What have we learned?

Barefoot running, popularized by Abebe Bikila, is not inherently good or bad; proper training and conditioning are key. However, research suggests that it can increase stress fractures and soreness in the calves, while also risking knee and hip injuries similar to those caused by athletic shoes.

Accelerated resolution therapy significantly reduces PTSD symptoms, researchers report

A study by the University of South Florida College of Nursing found that Accelerated Resolution Therapy (ART) substantially reduced PTSD symptoms, including depression and anxiety, after just one to four sessions. The therapy uses eye movements to process traumatic memories, resulting in a significant improvement in symptoms.

Landmark HIV treatment-as-prevention study shows additional health benefits, cost-effectiveness

A landmark HIV treatment-as-prevention study has found that providing antiretroviral treatment to HIV-infected individuals earlier, when their immune systems are healthier, delays AIDS-related health events such as chronic herpes simplex virus and tuberculosis. Earlier treatment is also cost-effective as it increases survival, prevents...

ASTRO awards 5 research grants

The American Society for Radiation Oncology (ASTRO) has awarded five physicians with research grants to promote the advancement of radiation therapy. The Junior Faculty Career Research Training Award and Residents/Fellows in Radiation Oncology Research Seed Grant Award support young researchers in radiation oncology, biology, physics, ...

Higgs excitations

Higgs excitations have been observed in a two-dimensional quantum gas near absolute zero temperature. The phenomenon, associated with spontaneous symmetry breaking, can lead to coordinated collective motion and is crucial in the Standard Model of Particle Physics.

Turbulences at a standstill

Theoretical physicist Dima Shepelyansky found that energy flows from large to small scales can be prevented under specific conditions, similar to the way electron currents are stopped in disordered solids. This discovery links chaos theory and turbulence, highlighting a phenomenon where energy threshold plays a crucial role.

UK welfare reform 'uninspiring' and adding to economic woes and inequality

A UK policy expert warns that the country's welfare reform policies are re-creating conditions that led to the 2007 economic crisis. The critic argues that the dominant political party's emphasis on reducing taxes and rolling back the state will lead to more poverty and economic instability.
