Light-driven molecular motors were first developed nearly 25 years ago. However, making these motors do actual work proved to be a challenge. In a new paper, scientists describe improvements that bring real-life applications closer.

Researchers have developed tiny, flexible devices that can wrap around individual nerve fibers without damaging them. The researchers combined flexible electronics and soft robotics techniques to develop the devices, which could be used for the diagnosis and treatment of a range of disorders, including epilepsy and chronic pain, or the control of prosthetic limbs.

Researchers co-led a study that will improve the detection of gravitational waves--ripples in space and time.

Interactions between wind turbines could reduce power output by 30% in proposed offshore wind farm areas along the East Coast, new research has found. In all, the farms could still meet 60% of the electricity demand of New England.

For most human proteins, there are no small molecules known to bind them chemically (so called 'ligands'). Ligands frequently represent important starting points for drug development but this knowledge gap critically hampers the development of novel medicines. Researchers at CeMM, in a collaboration with Pfizer, have now leveraged and scaled a method to measure the binding activity of hundreds of small molecules against thousands of human proteins. This large-scale study revealed tens of thousands of ligand-protein interactions that can now be explored for the development of chemical tools and therapeutics. Moreover, powered by machine learning and artificial intelligence, it allows unbiased predictions of how small molecules interact with all proteins present in living human cells. These groundbreaking results have been published in the journal Science (DOI: 10.1126/science.adk5864), and all generated data and models are freely available for the scientific community.

Researchers have developed a compact and lightweight single-photon airborne lidar system that can acquire high-resolution 3D images with a low-power laser. This advance could make single-photon lidar practical for air and space applications such as environmental monitoring, 3D terrain mapping and object identification.

Extracting natural gas from shale formations can provide an abundant, lower-carbon footprint fossil fuel, but also creates concerns over increased methane emissions. Researchers have now developed a new tool that can estimate the emission potential of shale wells after they are no longer active.

A newly developed nanomaterial that mimics the behavior of proteins could be an effective tool for treating Alzheimer's and other neurodegenerative diseases. The nanomaterial alters the interaction between two key proteins in brain cells -- with a potentially powerful therapeutic effect.

A recent study utilized ground-based instruments to measure solar-induced fluorescence (SIF) that reflect plant health and photosynthesis.

Oil is an important natural resource for many industries, but it can lead to serious environmental damage when accidentally spilled. While large oil spills are highly publicized, every year there are many smaller-scale spills into lakes, rivers and oceans. The longer that oil remains in freshwater, the more chemical changes it undergoes, creating products that can persist in the environment.

A team of researchers has made a significant breakthrough in the field of organic photovoltaics.

An unexpected discovery surprised a scientist: nanometer-sized diamond particles, which were intended for a completely different purpose, shone brightly in a magnetic resonance imaging experiment -- much brighter than the actual contrast agent, the heavy metal gadolinium. Could diamond dust -- in addition to its use in drug delivery to treat tumor cells -- one day become a novel contrast agent used for MRI?

Scientists have watched a molecule move across a graphite surface in unprecedented detail. It turns out this particular molecule moves like a Moon lander -- and the insights hold potential for future nanotechnologies.

Freeze casting is an elegant, cost-effective manufacturing technique to produce highly porous materials with custom-designed hierarchical architectures, well-defined pore orientation, and multifunctional surface structures. Freeze-cast materials are suitable for many applications, from biomedicine to environmental engineering and energy technologies.

Researchers have pioneered a breakthrough in ferroelectric material development. They've engineered a novel displacement-type ferroelectric material boasting remarkable dielectric properties. Their achievement includes the successful synthesis of rubidium niobate (RbNbO3), a compound previously deemed challenging to produce under pressures exceeding 40,000 atmospheres. Additionally, they characterized how polarization changes across a wide temperature range during phase transitions. This breakthrough can lead to new design guidelines for ferroelectric materials.

Two of the biggest challenges faced by new and potential electric vehicle (EV) drivers are range anxiety and speed of charging, but these shouldn't have to be challenges at all. Researchers discovered that a change in refueling mindset, rather than improving the size or performance of the battery, could be the answer to these concerns.

'Bookworm' is a cute thing to call a voracious reader, but actual bookworms -- as well as microorganisms and time -- break down the flour pastes commonly used to keep old publications in one piece. Now, researchers have analyzed the proteins in wheat-based glues applied in historic bookbinding to provide insights on their adhesiveness and how they degrade. This information could help conservators restore and preserve treasured tomes for future generations.

A new technique can generate batches of certain entangled states in a quantum processor. This advance could help scientists study the fundamental quantum property of entanglement and enable them to build larger and more complex quantum processors.

Researchers discovered that light can cause evaporation of water from a surface without the need for heat. This 'photomolecular effect' could be important for understanding climate change and for improving some industrial processes.

A new survey has found that for residents living within three miles of a large-scale solar development, positive attitudes outnumbered negative attitudes by almost a 3-to-1 margin. Researchers surveyed almost 1,000 residents living near solar projects.
