Researchers with the Lawrence Berkeley National Laboratory and the University of California Berkeley have measured what is believed to be the smallest force yet recorded – 42 yoctonewtons, or a septillionth of a newton.  Read More

A lab mouse body, one week after after the start of the PARS process – the arrow in the mi...

Ordinarily, when scientists want to see specific cells within a piece of biological tissue, they first have to remove that tissue from the body, slice it very thin, then examine those two-dimensional slices using a microscope. Imagine, though, if the tissue could be made transparent – seeing tagged cells within it would be sort of like looking at three-dimensional bubbles inside an ice cube. Well, that's just what a team at Caltech have done using a technique known as PARS, or perfusion-assisted agent release in situ.  Read More

Scientists suggest looking for industrial pollution as a new way of searching for extrater...

According to researchers at the Harvard-Smithsonian Center for Astrophysics (CfA), we might soon be able to detect hints of technologically advanced alien civilizations by measuring high levels of polluting gases in the atmospheres of distant exoplanets. The approach should become viable soon after the James Webb Space Telescope (JWST) is launched in late 2018.  Read More

iPipet is an iPad app that uses glowing dots to guide lab techs as they're pipetting

If you've ever worked in a laboratory, or even if you've just seen them on TV, then you're probably familiar with the important but monotonous task of pipetting. To make it easier and less prone to errors, a team at the MIT-affiliated Whitehead Institute has created iPipet, an app that allows an iPad to visually guide "pipetters" in their work.  Read More

A new study predicts that global crop yields could fall by up to ten percent in the next 3...

A new study has examined the potentially disastrous implications that a combination of global warming and air pollution could have on crop yields by the year 2050. The research is one of the first projects to take into account a combination of the two dangers, and highlights the humanitarian crisis that could arise should the threat not be tackled head-on.  Read More

The nanoprop is able to easily pass between polymer chains, like those present in bodily f...

All over the world, scientists are creating microscopic "nanobots" for purposes such as delivering medication to precisely-targeted areas inside the body. In order for those tiny payload-carrying robots to get to their destination, however, they need some form of propulsion. Although some systems are already in development, a team of Israeli and German scientists may have come up with the most intriguing one yet, in the form of what they claim is the world's smallest propeller.  Read More

The researchers have engineered yeast to produce casein, a milk protein

Many people say they can’t go vegan because of their addiction to dairy. But that excuse could soon be past its sell-by date if a team of biohackers in California succeeds in scaling up production of a cheese that contains no animal by-products. They call it Real Vegan Cheese. Their aim is to offer a sustainable food alternative with the same nutritional value – and taste – as non-vegan cheese.  Read More

The Earlobe Arterial Blood Collector (EABC) could allow astronauts to measure the impact o...

A novel technique developed by the Microgravity Centre, Brazil, could allow astronauts aboard the ISS to measure the effect that prolonged exposure to microgravity can have on human lung capacity. Research like this is a vital stepping stone to understanding the safety measures needed to keep astronauts alive and healthy on a long journey, such as NASA's planned mission to Mars.  Read More

The Stanford University system uses a glass layer patterned with micro-pyramids and cones ...

Photovoltaic cells are one of the more promising alternative energy sources. Mechanically they are very simple, with no moving parts, and are clean and emission-free. Unfortunately they are also inefficient. One of the reasons for this is that they overheat, a problem that a Stanford University team under electrical engineering professor Shanhui Fan is addressing with the development of a thin glass layer that makes solar cells self-cooling.  Read More

The camera uses diffused light instead of mirrors to see around corners

Peeking around a corner has long been a staple of spy films and TV, from Get Smart to 007. Researchers at the University of Bonn in Germany and the University of British Columbia in Vancouver, Canada have found a better way than poking a makeup mirror about, however: a camera system that can reconstruct the shape of objects using diffusely scattered laser light.  Read More
