Vanadium-dependent nitrogenase can bind two CO molecules simultaneously
Through the biological fixation of the element nitrogen by the enzyme nitrogenase, organisms gain access to molecular nitrogen (N2) in the Earth's atmosphere, which is essential for building cellular structures. In addition, a vanadium-dependent vari.....»»
Smart vest turns fish into underwater spies, providing a glimpse into aquatic life like never before
Traditional techniques for observing fish behavior, largely dependent on vision-based systems, face substantial limitations, such as a confined range of observation and a limited duration of operation underwater. In response to these challenges, a re.....»»
New molecular device unlocks potential for targeted drug delivery and self-healing materials
In a new breakthrough that could revolutionize medical and material engineering, scientists have developed a first-of-its-kind molecular device that controls the release of multiple small molecules using force......»»
A simple, inexpensive way to make carbon atoms bind together
The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon—a carbon atom bond.....»»
EV startup bankruptcies complicate future of software-dependent vehicles
In an era where each new model contains proprietary software, company failures can have grave implications for vehicle functionality......»»
Click chemistry: Research team creates 150 new compounds
Cold Spring Harbor Laboratory (CSHL) chemists have created a new collection of molecular compounds and begun testing them as potential leads in the search for new drugs. Among these molecules, they found several that show promise for development as a.....»»
New research shows key molecules within nerve cells persist throughout life
After two decades in the United States, Martin Hetzer returned home to Austria in 2023 to become the 2nd President of the Institute of Science and Technology Austria (ISTA). A year into his new role, the molecular biologist remains engaged in the rea.....»»
New method reveals secrets of protein interactions with potential for drug discovery
Scientists from the University of Oulu (Finland) and Texas A&M University (U.S.), have developed a new method to study how proteins interact with small ligand molecules, paving the way, for example, for faster and more efficient drug discovery......»»
Attack and defense in the microverse: How small RNA molecules regulate viral infections of bacteria
Viruses need hosts. Whether it's measles, the flu or coronavirus, viral pathogens cannot multiply or infect other organisms without the assistance of their hosts' cellular infrastructure. However, humans are not the only ones affected by viruses: ani.....»»

Researchers show depth-dependent responses of soil organic carbon under nitrogen deposition
In a study published in Global Change Biology, scientists from the Institute of Earth Environment and the South China Botanical Garden of the Chinese Academy of Sciences have shed light on understanding the effects of nitrogen addition on soil organi.....»»
Researchers reveal evolutionary path of important proteins
New research from the University of Wisconsin–Madison decodes the evolutionary pathway of regulatory proteins, the molecules that help control gene expression......»»
Tesla’s $25,000 car means tossing out Henry Ford"s 100-year-old assembly line
Instead of a large, rectangular car moving along a linear conveyer belt, parts are assembled simultaneously in dedicated areas and then all put together at the end......»»
Perceptions of "good" schools are heavily dependent on the preparation of the students entering them, study finds
Are schools that feature strong test scores highly effective, or do they mostly enroll students who are already well-prepared for success? A study co-authored by MIT scholars concludes that widely disseminated school quality ratings reflect the prepa.....»»
How eutrophication and climate change alter food webs in the Baltic Sea
Phytoplankton is the primary energy source for all marine ecosystems: These tiny plants floating in the seawater use photosynthesis to bind energy in the form of biomass, which is then passed on step by step in the marine food webs all the way to dif.....»»
Chiharu Shiota’s String Art Installations Highlight the Ties That Bind Us
The artist's signature installations explore abstract concepts of meaning and memory. The post Chiharu Shiota’s String Art Installations Highlight the Ties That Bind Us appeared first on Make: DIY Projects and Ideas for Makers......»»
Researchers challenge the limits of molecular memory, opening the door to the development of molecular chips
Some molecules respond to external light pulses by changing their structure and holding certain states that can be switched from one to another. These are commonly referred to as photoswitches and usually have two possible states. Recently, however,.....»»
Researchers invent artificial intelligence model to design new superbug-fighting antibiotics
Researchers at McMaster University and Stanford University have invented a new generative artificial intelligence model that can design billions of new antibiotic molecules that are inexpensive and easy to build in the laboratory......»»
Can this cheap Samsung phone beat the Galaxy S24? We found out
Two of Samsung's 2024 smartphones — the Galaxy S24 and Galaxy A55 — are simultaneously similar to and different from each other. Here's which one to buy......»»
Antibodies against anything? AI tool adapted to make them
Right now, making antibodies means immunizing animals. But that may change. Enlarge Antibodies are incredibly useful. Lots of recently developed drugs rely on antibodies that bind to and block the activity of specific p.....»»
Molecular crystal motors move like microbes when exposed to light
At first glance, Rabih O. Al-Kaysi's molecular motors look like the microscopic worms you'd see in a drop of pond water. But these wriggling ribbons are not alive; they're devices made from crystallized molecules that perform coordinated movements wh.....»»
