Food for thought

Chemical fertilizers get bad press, with some justification. Their use can pollute water supplies and generate significant greenhouse-gas emissions. But they are a great way to increase crop yields: They help grow food. And in sub-Saharan Africa that means they can help fill an empty stomach and save lives. Parts of Africa are in dire…

Creative tensions

Creative tensions

True scientific creativity is often thought of as the preserve of independent investigators working in an environment with no practical or political concerns that bother many other workers. The truth is that far from being creative, most scientists spend most of their time worrying about funding, sitting in meetings, and dealing with administrative bureaucracy. But,…

Overdue: a US advisory board for research integrity

When it comes to promoting rigor and scientific integrity, American research institutions tend to falter. Taking best practice is not straightforward, and faculty members can be resistant to top-down instructions. Therefore, on a day-to-day basis, the conventions that research groups have for documenting, analyzing, and allocating credit to methods and results are often less than…

Ultra-large virtual molecular libraries throw open chemical space

Ultra-large virtual molecular libraries throw open chemical space

Drug discovery is an extremely difficult process. Pharmaceutical companies prize efficiency, so many potential lead compounds companies have iterations of what they already know, and rely on previously exploited molecular scaffolds (the basic structure of a molecule). The need to diversify molecular scaffolds to improve the chances of success in drug discovery has been referred…

Trump’s goal to eradicate the HIV epidemic in the United States is achievable — yet remote

Trump’s goal to eradicate the HIV epidemic in the United States is achievable — yet remote

For the past two years, HIV advocacy groups have found little to like about the administration of US President Donald Trump. Trump has acted to reduce access to health care programs, threatened to cut funding for the global President’s Emergency AIDS Relief Plan (PEPFAR), and stigmatized some communities at high risk. It is therefore no…

Researchers develop low-cost 3D printed polymeter for classroom use

Researchers develop low-cost 3D printed polymeter for classroom use

Science and technology classes, especially at the university level, often require specialist equipment that can be costly and difficult for students. This is where 3D printing can be helpful, offering a low-cost method of manufacturing components for technical learning devices. In his paper Pavel Bernard of Jagiellonian University and James Mendez of Indiana University have…

Plans to implement 3D printing in more schools in the future, a Bet 2020 report

We visited the BETT 2020 Education Technology Industry Show in London Excel to see the latest trends in 3D printing for the education sector and to learn how technology is incorporated into the current curriculum. More than 800 exhibiting companies had booths from 3D printing companies including Dremel, Makerbot and Kraftbot partner Maker Red Box….

This 3D printable “lab-grade” open-source microscope will set you back $ 18

A team of researchers from the University of Bath, UK, has developed an open-source design for a 3D printable “laboratory-grade” microscope, which costs as little as $ 18. The OpenFlexure microscope is a fully automated device with motorized sample positioning, focus control, and an accurate mechanical stage. Along with being easy to use, the microscope…
