Albumin, gelatin and casein are used for the synthesis of nanoparticles.

Generating gelatin-based nanoparticles

What is common between albumin, gelatin and casein? They are all proteins used for the synthesis of nanoparticles. Desolvation is a common process to construct nanoparticles in which this balance of electrostatic and hydrophobic interactions is disturbed, causing a protein to damage its 3D structure.

Researchers from the Centre for Cellular and Molecular Biology, Hyderabad, have studied the desolvation process of gelatin. This will provide insights into the gelatin nanoparticle assembly and could improve the process of drug delivery through nanoparticles.

A 3D virtual laboratory

SimYog, an Indian start-up, presented one of their latest innovations - Compliance-Scope at the IEEE EMC Conference recently. It is a 3D, virtual EMI EMC laboratory that allows users to explore and improve circuit board and other hardware. It also allows users to create a 3D electromagnetic simulation of the hardware, with the ability to be embedded in the circuit board and validates the function of its electrical components and detect errors. The device not only allows users to diagnose and find solutions in an immersive 3D virtual space.

How acidic is rain?

Acid rain is quite a popular term these days. Environmental scientists describe it as an adverse effect of increasing pollution due to recent human activities. But even before humans started evolving on earth, proof of acid rains have been found.

It was around 250 million years ago; the most devastating case of mass extinction in earth’s history was caused by acid rain due to volcanic eruption in the Siberian region. Acidity of rain is measured using the pH scale. A pH of less than 7 is acidic and a pH greater than 7 is basic. Surprisingly, rain is always acidic compared to water. Scientists consider a pH of 5.6 as neutral pH in the case of rainwater. Sulphur dioxide and nitrogen dioxide, emitted from cars and various industries, make rainwater more
acidic. So how acidic could rainwater be? Studies say it could be as low as pH 2. This highly acidic water can directly affect human eye and skin. But fortunately, rains with high acidity are very rare.

Visual guides

A study published in Psychological Science found that taking photos during an experience helped people remember visuals more accurately, even when they did not revisit their photos. However, snapping pictures also appeared to decrease how much spoken information people retained. The findings suggest that the process of looking around for what to photograph "actually causes you to encode visual content and remember it,” said Alix Barasch, one of the authors and an assistant professor at the New York University.

Random choice-making

The ability to behave randomly can be a great asset. Recently, a team from Europe pitted humans and computers against one another in a series of tasks designed to measure random choice-making. Around age 25, the researchers determined, people are best able to produce a random result.


Documentary

Particle Fever

Particle Fever follows six scientists during the launch of the Large Hadron Collider, as they conduct experiments in an effort to comprehend the origins of the universe. Directed by Mark Levinson, a physicist turned filmmaker, the documentary is a celebration of discovery, revealing the very human stories behind this epic machine.

Triggers of a autoimmune attack

A research team led by Michael Carroll of Boston Children's Hospital, USA and Harvard Medical School, USA, has spent years investigating mouse models of lupus to better understand the ins and outs of autoimmune diseases.

Their latest findings, published in Cell, reveal that rogue B cells can trigger an 'override' that launches the body into an autoimmune attack.

Visualising tumours

Researchers at Sanford Burnham Prebys Medical Discovery Institute, USA, have developed a proof-of-concept nanosystem that dramatically improves the visualisation of tumours. The novel approach generates bright tumour signals by delivering 'quantum dots' to cancer cells without any toxic effects.
