Computer Models Reveal Quantum Effects in Biological Oxygen Transport

July 18, 2014 3:41 pm | by Trinity College | News | Comments

Physicists have created a unique combination of computer models, based on the theory of quantum mechanics, and applied them to a previously well-characterized protein found in muscle to develop a new picture of how biomolecules transport and store oxygen (O2). In doing so, the team has shown how the process of respiration, which is fundamental in humans and other vertebrates, exploits quantum mechanical effects working on tiny scales.

Chemical Weapons: Engineering Enzymes to Neutralize Nerve Agents

June 17, 2014 2:15 pm | by The University of Tennessee | News | Comments

Researchers at The University of Tennessee are a step closer to creating a prophylactic drug that would neutralize the deadly effects of the chemical weapons used in Syria and elsewhere. Jeremy Smith, UT-ORNL Governor’s Chair and an expert in computational biology, is part of the team that is trying to engineer enzymes — called bioscavengers — so they work more efficiently against chemical weapons. 

The quest to create artificial blood is big business, with the past 25 years seeing up to £2 billion invested globally on research into a usable alternative and many major US companies falling by the wayside in the hunt for a substitute.

The Quest for Blood: Finding a Long-lasting, One-size-fits-all Viable Substitute

June 12, 2014 3:47 pm | by University of Essex | News | Comments

Every day thousands of people around the world have their lives saved or improved thanks to someone giving blood. But imagine how many more lives could be saved if a long-lasting blood substitute could be found, which could easily be stored at room temperature and available to all patients, regardless of their blood type. This is the challenge a team of scientists at the University of Essex are hoping to overcome with their Haem02 project

Beer Brewing Waste could Help Bone Regeneration

June 9, 2014 2:38 pm | by Universidad Politécnica de Madrid | News | Comments

Researchers have developed biomaterials for bone regeneration from beer brewing waste. The waste obtained from the beer brewing process contains the main chemical components found in bones (phosphorus, calcium, magnesium and silica). After undergoing modification processes, this waste can be used as support or scaffold to promote bone regeneration for medical applications, such as coating prosthesis or bone grafts.

Sperm-Inspired Robots Controlled by Magnetic Fields

June 4, 2014 8:00 pm | by American Institute of Physics (AIP) | News | Comments

A team of researchers has developed sperm-inspired microrobots, which can be controlled by oscillating weak magnetic fields. The 322 micron-long robots consist solely of a head coated in a thick cobalt-nickel layer and an uncoated tail. When the robot is subjected to an oscillating field of about the strength of a decorative refrigerator magnet, it experiences a magnetic torque on its head, which causes its flagellum to oscillate

Most Detailed Images Yet of Tiny Cellular Machines Captured

June 2, 2014 7:37 pm | by Kelly April Tyrrell, University of Wisconsin-Madison | News | Comments

A grandfather clock is, on its surface, a simple yet elegant machine. Tall and stately, its job is to steadily tick away the time. But a look inside reveals a much more intricate dance of parts, from precisely-fitted gears to cable-embraced pulleys and bobbing levers. Like exploring a clock's the inner workings, researchers are digging into the inner workings of the tiny cellular machines that help make all of the proteins our bodies need.

Longevity Gene May Boost Brain Power

May 14, 2014 3:32 pm | by NIH | News | Comments

Scientists showed that people who have a variant of a longevity gene, called KLOTHO, have improved brain skills such as thinking, learning and memory regardless of their age, sex, or whether they have a genetic risk factor for Alzheimer’s disease. Increasing KLOTHO gene levels in mice made them smarter, possibly by increasing the strength of connections between nerve cells in the brain.
