Researchers have developed a new microscopy method that allows scientists to see the building blocks of 'smart' materials being formed at the nanoscale.

Protein synthesis is a finely tuned process in the cell by macromolecules known as ribosomes. Which regulators are responsible for controlling protein synthesis in the brain? To address this question, researchers studied the structure of the brain's ribosomal complexes in great detail. The team was able to identify a new factor which is also involved in controlling brain development.

Researchers have devised a brain machine interface (BMI) that allows mice to learn to guide a cursor using only their brain activity. By monitoring this mouse-controlled mouse moving to a target location to receive a reward, the researchers were able to study how the brain represents intentional control.

Chemists have synthesized extremely unusual compounds. Their central building block is a silicon atom. Different from usual, however, is the arrangement of the four bonding partners of the atom, which are not in the form of a tetrahedron around it, but flat like a trapezoid. This arrangement is usually energetically extremely unfavorable, yet the molecules are very stable.

The more chaotic things get, the harder it is for people with clinical anxiety and/or depression to make sound decisions and to learn from their mistakes. On a positive note, overly anxious and depressed people's judgment can improve if they focus on what they get right, instead of what they get wrong, suggests a new study.

It took fifteen years of imaging and nearly three years of stitching the pieces together to create the largest image ever made, the 8-trillion-pixel mosaic of Mars' surface. Now, the first study to utilize the image in its entirety provides unprecedented insight into the ancient river systems that once covered the expansive plains in the planet's southern hemisphere.

Seafood is the world's most highly traded food commodity, and reports of seafood mislabeling have increased over the past decade. However, proof of the environmental effects of mislabeled seafood has been scant as has research. So, researchers analyzed the impact of seafood mislabeling on marine population health, fishery management effectiveness, and habitats and ecosystems in the United States,...

A research team has developed a novel computational tool that can reconstruct and visualize three-dimensional (3D) shapes and temporal changes of cells, speeding up the analyzing process from hundreds of hours by hand to a few hours by the computer. Revolutionizing the way biologists analyze image data, this tool can advance further studies in developmental and cell biology, such as the growth of...

Surgery, in addition to treatments like chemotherapy and radiation therapy, may increase the length of survival for metastatic breast cancer patients, according to researchers.

Cornell University is developing a system to extract energy from cattle manure to meet the campus's peak demands for heat in the winter months. Scientists involved with the project give a detailed analysis of the issues required to make this work, including scientific, economic, and energy policy considerations.

Pregnant women who are infected with SARS-CoV-2, the virus that causes COVID-19, during the third trimester are unlikely to pass the infection to their newborns, new research suggests. The study followed 127 pregnant women who were admitted to Boston hospitals during the spring of 2020. Among the 64 pregnant women who tested positive for SARS-CoV-2, no newborns tested positive for the virus.

Understanding aerosol concentrations and persistence in public spaces can help determine infection risks. However, measuring these concentrations is difficult, requiring specialized personnel and equipment. Now, researchers demonstrate that a commercial hand-held particle counter can be used for this purpose and help determine the impacts of risk-reducing measures, like ventilation improvements.

Discovering wide variation in hospitals' COVID-19 survival rates, researchers found that the levels of novel coronavirus in the surrounding community was likely the driving factor.

Wearing a mask may not be enough to prevent the spread of COVID-19 without social distancing. Researchers tested how different types of mask impacted the spread of droplets that carry the coronavirus when we cough or sneeze. Every material tested dramatically reduced the number of droplets that were spread. But at distances of less than 6 feet, enough droplets to potentially cause illness still...

A new study by neuroscientists demonstrates that the brain does not remap itself even with long-term bionic limb use, posing challenges for the development of realistic prosthetic limbs.

Scientists present important new constraints showing that plate tectonics started relatively slow, although the early Earth's interior was much hotter than today.

Compared to the first peopling of Polynesia, the settlement of the Mariana Islands in the Western Pacific, which happened around 3,500 years ago, has received little attention. Researchers have now obtained answers to long debated questions regarding the origin of the first colonizers of the Marianas and their relationship to the people who initially settled in Polynesia.

The lockdowns that resulted from the COVID-19 pandemic have reduced greenhouse gas emissions. However, in the recovery phase, emissions could rise to levels above those projected before the pandemic. It all depends on how the stimulus money that governments inject into their economies is spent. A team of scientists has quantified how different recovery scenarios may affect global emissions and...

A team of researchers has developed a method that allows them to study the assembly process for large protein complexes in detail for the first time. As their case study, the biologists chose one of the largest cellular complexes: the nuclear pore complex in yeast cells.

A research team has discovered a tree hyrax in the Taita Hills, Kenya, which may belong to a species previously unknown to science.

Scientists have developed a new way to cure adhesives using a magnetic field.

A new study assembled an array of experts to highlight major trends that will impact the world's forests, and the people living around them, in the decade ahead. These trends include drought, viral outbreaks and vast infrastructure expansions across the globe. According to the researchers, a global strategy for human-nature interaction must be developed if we intend on ensuring the survival of...

An unusual study that involved bar coding and tracking the behavior of thousands of individual honey bees in six queenless bee hives and analyzing gene expression in their brains offers new insights into how gene regulation contributes to social behavior.

A team of engineers is using ideas taken from paper-folding practices to create a sophisticated alternative to 3D printing.
