Researchers at JILA have developed a new waveguide structure that coaxes light waves into traveling along at the same speed, producing well-synchronized photons firing out of the system. The breakthrough enables electromagnetic radiation with peak powers approaching a megawatt and produces nanometer-scale light waves.
Studies have found a direct correlation between global warming and biological changes in plants and animals globally. Over 1,200 species have undergone changes consistent with temperature change influencing various traits.
Research reveals cocaine causes harm to brain cells that trigger feelings of pleasure, potentially explaining addiction and depression. The study found significant lower levels of dopamine neurons in cocaine users compared to non-users.
In the Phase II study, natalizumab demonstrated higher rates of clinical remission compared to placebo at multiple time points. The highest rate of remission was observed in the dual 3 mg/kg dose group, with a maximal response of 71%.
Researchers confirm previous detection of chlorine in Io's plasma torus and model the breakdown of salt into sodium and chlorine atoms, providing insights into Io's volcanic activity and its potential meteoritic origins.
A Phase II study published in NEJM found that natalizumab significantly reduced new gadolinium-enhancing lesions by up to 93% and the number of patients experiencing relapses by 50%. The treatment was well-tolerated, with common adverse events including infection and rash.
A Stanford study finds that medications for heart disease, including warfarin, beta blockers, and ACE inhibitors, are underused in outpatient settings. The researchers urge improved education, quality-improvement practices, and patient involvement to address this issue and reduce complications.
A new testing method for Huntington's disease (HSS) has been discovered by researchers at Oregon Health & Science University and UCSF. The test uses magnetic resonance imaging (MRI) to identify the 'eye of the tiger sign' in patients with PANK2 mutations, a gene linked to HSS and Parkinson's disease.
A study analyzing 143 scientific papers and personal backyard recordings reveals that animals and plants are shifting their behaviors and seasonal timing due to a 0.6°C global temperature increase. In the temperate zone, species are shifting about five days earlier every ten years in response to warming temperatures.
