Scientists see an ultra-fast movement on surface of HIV virus      (via sciencedaily.com)     Original source 

Seeing a glycoprotein on the envelope of the HIV virus snap open and shut in mere millionths of a second is giving investigators a new handle on the surface of the virus that could lead to broadly neutralizing antibodies for an AIDS vaccine. Being able to attach an antibody specifically to this little structure that would prevent it from popping open would be key.

A sleeker facial recognition technology tested on Michelangelo's David      (via sciencedaily.com)     Original source 

Many people are familiar with facial recognition systems that unlock smartphones and game systems or allow access to our bank accounts online. But the current technology can require boxy projectors and lenses. Now, researchers report on a sleeker 3D surface imaging system with flatter, simplified optics. In proof-of-concept demonstrations, the new system recognized the face of Michelangelo's David just as well as an existing smartphone system.

A clutch stretch goes a long way      (via sciencedaily.com)     Original source 

New results reveal a new mode of force transmission in which dynamic molecular stretching bridges the extracellular matrix and flowing F-actin moving at different speeds. This discovery underscores the necessity of molecular elasticity and random coupling for sufficiently transmitting force. The findings also call for revising the role of molecular unfolding.

Gut bacteria can process dietary fiber into an anti-allergy weapon      (via sciencedaily.com)     Original source 

Short-chain fatty acids (SCFAs), which are produced by gut bacteria from dietary fiber, regulate our immune system, but the mechanism of their action remains unknown. In a recent study, researchers investigated how SCFAs interact with mast cells, a type of white blood cell that plays a central role in allergic reactions. Their findings and insights could lead to innovative and effective anti-allergy medications, supplements, and diets, paving the way for healthier lives.

How to run a password update campaign efficiently and with minimal IT costs      (via sciencedaily.com)     Original source 

Computer scientists found that email notifications to update passwords potentially yielded diminishing returns after three messages. They also found that a prompt to update passwords while users were trying to log in was effective for those who had ignored email reminders. Researchers also found that users whose jobs didn't require much computer use struggled the most with the update.

Shining a new light on the tug-of-war between virus and host      (via sciencedaily.com)     Original source 

The interplay between ribonucleic acid (RNA) and proteins is not only important for maintaining cellular homeostasis but is also at the center of the tug-of-war between virus and host. Until now, there has been no method to globally map direct interactions of individual RNA regions in an unbiased fashion without the need for genetic modification of the target RNA or cell. Researchers have now developed a breakthrough tool that overcomes this limitation.

Engineers develop hack to make automotive radar 'hallucinate'      (via sciencedaily.com)     Original source 

Engineers have demonstrated a system they've dubbed 'MadRadar' for fooling automotive radar sensors into believing almost anything is possible. The technology can hide the approach of an existing car, create a phantom car where none exists or even trick the radar into thinking a real car has quickly deviated from its actual course. And it can achieve this feat in the blink of an eye without having any prior knowledge about the specific settings of the victim's radar, making it the most troublesome threat to radar security to date.

How seahorse-like toxins kill insects      (via sciencedaily.com)     Original source 

Insect-killing bacteria typically release toxins to slay their hosts. The bacterium Photorhabdus luminescens, for example, pumps insect larvae full of the lethal 'Makes caterpillars floppy 1' (Mcf1) toxin, leading them to first become droopy and then dead. However, it has so far been a mystery how Mcf1 unfolds its devastating effect. Researchers successfully used cryo-electron microscopy (cryo-EM) and biochemical assays to characterize the first-ever Mcf1 structure, allowing them to propose a molecular mechanism of the toxin's action. Understanding how bacterial toxins perform their deadly task in such detail is very useful for engineering novel biopesticides, thereby reducing the use of barely specific chemical agents with harmful side effects for the ecosystem.

Asparagus and orchids are more similar than you think      (via sciencedaily.com)     Original source 

How is a beech leaf constructed? What determines the appearance of an asparagus? A new 'encyclopaedia' helps us learn more about the building blocks of plants. The encyclopaedia, probably the largest of its kind, could be used to improve targeted plant breeding efforts, to make them both more climate-resilient and more easily digestible.
