Better integrated circuits with glide symmetry8h
Surface plasmon polaritons (SPPs) are highly localized surface waves on the interface between metal and dielectric in the optical frequency band.

Rules of the road: The navigational 'strategies' of bacteria in motion1d
Bacteria that move around live on the edge. All the time. Their success, be it in finding nutrients, fending off predators or multiplying, depends on how efficiently they navigate through their confining microscopic habitats. Whether these habitats are in animal or plant tissues, in waste, or in other materials. In a recent paper published in PNAS, a team of researchers led by McGill University ha
COVID-19 may alter gray matter in the brain1d
COVID-19 patients who receive oxygen therapy or experience fever show reduced gray matter volume in the frontal-temporal network of the brain, according to a new study. Researchers found lower gray matter volume in this brain region was associated with a higher level of disability among COVID-19 patients, even six months after hospital discharge. Gray matter is vital for processing information in

This stinks: New research finds sense of smell and pneumonia linked1d
EAST LANSING, Mich. – An acute loss of smell is one of the most common symptoms of COVID-19, but for two decades it has been linked to other maladies among them Parkinson's disease and dementia. Now, a poor sense of smell may signify a higher risk of pneumonia in older adults, says a team of Michigan State University researchers.

To address patients' expectations for antibiotic prescribin
Interdisciplinary consults can help primary care docs treat patients with chronic pain1d
Between 11% to 40% of adults in the United States experience chronic pain, and primary care physicians may feel ill-equipped to effectively and safely care for patients with chronic pain, addiction or both.

Newer class of fluoroquinolone antibiotics may present reduced risk of tendon ruptures1d
It's widely understood that people taking a common class of antibiotics, like ciprofloxacin and levofloxacin, run the risk of tendonitis and tendon ruptures. However, a new analysis sheds light on newer, third-generation fluoroquinolones and suggests they may have a lower risk of Achilles tendon rupture.
Combination of psychotherapy and pharmacotherapy more effective in treating depression1d

Structure elucidation of the elusive Enzyme I monomer reveals the molecular mechanisms linking oligomerization and enzymatic activity [Biophysics and Computational Biology]1d
Enzyme I (EI) is a phosphotransferase enzyme responsible for converting phosphoenolpyruvate (PEP) into pyruvate. This reaction initiates a five-step phosphorylation cascade in the bacterial phosphotransferase (PTS) transduction pathway. Under physiological conditions, EI exists in an equilibrium between a functional dimer and an inactive monomer. The monomer–dimer equilibrium is a crucial…

A key requirement for synaptic Reelin signaling in ketamine-mediated behavioral and synaptic action [Neuroscience]1d
Ketamine is a noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist that produces rapid antidepressant action in some patients with treatment-resistant depression. However, recent data suggest that ∼50% of patients with treatment-resistant depression do not respond to ketamine. The factors that contribute to the nonresponsiveness to ketamine’s antidepressant action remain unclear. Recent
Bilin-dependent regulation of chlorophyll biosynthesis by GUN4 [Plant Biology]1d
Biosyntheses of chlorophyll and heme in oxygenic phototrophs share a common trunk pathway that diverges with insertion of magnesium or iron into the last common intermediate, protoporphyrin IX.
