New research could help millions who suffer from 'ringing in the ears'
In the largest clinical trial of its kind, researchers show that combining sound and electrical stimulation of the tongue can significantly reduce tinnitus, commonly described as 'ringing in the ears.' They also found that therapeutic effects can be sustained for up to 12 months post-treatment.

New M92 stellar stream discovered
A team of astronomers using the Canada-France-Hawaii Telescope discovered a new stellar stream emanating from the M92 globular cluster. This new stream suggests that M92 is actively being disrupted by tidal forces caused by our Milky Way Galaxy. This discovery utilized high quality data obtained as part of the Canada-France-Imaging-Survey (CFIS) using MegaCam at CFHT and from the Pan-STARRS 1 (PS1

New study: Forests are still underrated as allies to curb rural poverty
Poverty is one of the greatest challenges facing humanity. Globally, one out of every 10 people lives in extreme poverty, defined by the World Bank as living on less than $1.90 per day. Many of them live in rural areas where the poverty rate is 17.2 per cent—more than three times higher than in urban areas. If current trends continue, the number of hungry people will reach 840 million or one ninth

Microbiota-modulated CART+ enteric neurons autonomously regulate blood glucose
The gut microbiota affects tissue physiology, metabolism, and function of both the immune and nervous systems. We found that intrinsic enteric-associated neurons (iEANs) in mice are functionally adapted to the intestinal segment they occupy; ileal and colonic neurons are more responsive to microbial colonization than duodenal neurons. Specifically, a microbially responsive subset of viscerofugal

Patterning and growth control in vivo by an engineered GFP gradient
Morphogen gradients provide positional information during development. To uncover the minimal requirements for morphogen gradient formation, we have engineered a synthetic morphogen in Drosophila wing primordia. We show that an inert protein, green fluorescent protein (GFP), can form a detectable diffusion-based gradient in the presence of surface-associated anti-GFP nanobodies, which modulate th

Engineering synthetic morphogen systems that can program multicellular patterning
In metazoan tissues, cells decide their fates by sensing positional information provided by specialized morphogen proteins. To explore what features are sufficient for positional encoding, we asked whether arbitrary molecules (e.g., green fluorescent protein or mCherry) could be converted into synthetic morphogens. Synthetic morphogens expressed from a localized source formed a gradient when trap

Coherently forming a single molecule in an optical trap
Ultracold single molecules have wide-ranging potential applications, such as ultracold chemistry, precision measurements, quantum simulation, and quantum computation. However, given the difficulty of achieving full control of a complex atom-molecule system, the coherent formation of single molecules remains a challenge. Here, we report an alternative route to coherently bind two atoms into a weak

Cartilage-inspired, lipid-based boundary-lubricated hydrogels
The lubrication of hydrogels arises from fluid or solvated surface phases. By contrast, the lubricity of articular cartilage, a complex biohydrogel, has been at least partially attributed to nonfluid, lipid-exposing boundary layers. We emulated this behavior in synthetic hydrogels by incorporating trace lipid concentrations to create a molecularly thin, lipid-based boundary layer that renews cont

Zeptosecond birth time delay in molecular photoionization
Photoionization is one of the fundamental light-matter interaction processes in which the absorption of a photon launches the escape of an electron. The time scale of this process poses many open questions. Experiments have found time delays in the attosecond (10 –18 seconds) domain between electron ejection from different orbitals, from different electronic bands, or in different directions. Her

Thermosensitive crystallization-boosted liquid thermocells for low-grade heat harvesting
Low-grade heat (below 373 kelvin) is abundant and ubiquitous but is mostly wasted because present recovery technologies are not cost-effective. The liquid-state thermocell (LTC), an inexpensive and scalable thermoelectric device, may be commercially viable for harvesting low-grade heat energy if its Carnot-relative efficiency ( r ) reaches ~5%, which is a challenging metric to achieve experimenta

Species richness and redundancy promote persistence of exploited mutualisms in yeast
Mutualisms, or reciprocally beneficial interspecific interactions, constitute the foundation of many ecological communities and agricultural systems. Mutualisms come in different forms, from pairwise interactions to extremely diverse communities, and they are continually challenged with exploitation by nonmutualistic community members (exploiters). Thus, understanding how mutualisms persist remai

The GATOR-Rag GTPase pathway inhibits mTORC1 activation by lysosome-derived amino acids
The mechanistic target of rapamycin complex 1 (mTORC1) couples nutrient sufficiency to cell growth. mTORC1 is activated by exogenously acquired amino acids sensed through the GATOR–Rag guanosine triphosphatase (GTPase) pathway, or by amino acids derived through lysosomal degradation of protein by a poorly defined mechanism.

Structural and mechanistic bases for a potent HIV-1 capsid inhibitor

X-ray crystallography, cryo–electron microscopy, and hydrogen-deuterium exchange experiments revealed that GS-6207 tightly binds two adjoin

Transient cortical circuits match spontaneous and sensory-driven activity during development
At the earliest developmental stages, spontaneous activity synchronizes local and large-scale cortical networks. These networks form the functional template for the establishment of global thalamocortical networks and cortical architecture. The earliest connections are established autonomously. However, activity from the sensory periphery reshapes these circuits as soon as afferents reach the cor

Apical stress fibers enable a scaling between cell mechanical response and area in epithelial tissue
Biological systems tailor their properties and behavior to their size throughout development and in numerous aspects of physiology. However, such size scaling remains poorly understood as it applies to cell mechanics and mechanosensing. By examining how the Drosophila pupal dorsal thorax epithelium responds to morphogenetic forces, we found that the number of apical stress fibers (aSFs) anchored

The physical microenvironment regulates cell behavior during tissue development and homeostasis.

The nucleus acts as a ruler tailoring cell responses to spatial constraints
The microscopic environment inside a metazoan organism is highly crowded. Whether individual cells can tailor their behavior to the limited space remains unclear.

Cell confinement below a resting nucleus size deforms the nucleus, which expands and stretches its
