Design of self-assembling protein nanomachines starts to click: A nanocage builds itself from engineered components

Design of self-assembling protein nanomachines starts to click: A nanocage builds itself from engineered components

A route for constructing protein nanomachines engineered for specific applications may be closer to reality. Biological systems produce an incredible array of self-assembling, functional protein tools. Continue reading

Hemorrhagic Fevers Can Be Caused by Body’s Antiviral Interferon Response

Hemorrhagic Fevers Can Be Caused by Body’s Antiviral Interferon Response

Hemorrhagic fevers caused by Lassa, dengue and other viruses affect more than one million people annually and are often fatal, yet scientists have never understood why only some virus-infected people come down with the disease and others do not. But now, virologists and immunologists at The Scripps Research Institute (TSRI) have found a major clue to the mystery of “hemorrhagic fever” syndromes Continue reading

Human stem cells successfully transplanted, grown in pigs

Human stem cells successfully transplanted, grown in pigs

One of the biggest challenges for medical researchers studying the effectiveness of stem cell therapies is that transplants or grafts of cells are often rejected by the hosts. This rejection can render experiments useless, making research into potentially life-saving treatments a long and difficult process. Now, researchers at the University of Missouri have shown that a new line of genetically modified pigs will host transplanted cells without the risk of rejection. Continue reading

Artificial lung the size of a sugar cube may replace animal testing

Artificial lung the size of a sugar cube may replace animal testing

What medications can be used to treat lung cancer, and how effective are they? Until now, drug companies have had to rely on animal testing to find out Continue reading

Marathon runners’ times develop in a U shape

Spanish researchers have demonstrated that the relationship between marathon running times and the age of the athlete is U-shaped. Continue reading

Intertwined evolution of human brain and brawn

Intertwined evolution of human brain and brawn

The cognitive differences between humans and our closest living cousins, the chimpanzees, are staggeringly obvious. Although we share strong superficial physical similarities, we have been able to use our incredible mental abilities to construct civilisations and manipulate our environment to our will, allowing us to take over our planet and walk on the moon while the chimps grub around in a few remaining African forests. But a new study suggests that human muscle may be just as unique Continue reading

New neural pathway found in eyes that aids in vision

New neural pathway found in eyes that aids in vision

A type of retina cell plays a more critical role in vision than previously known, a team led by Johns Hopkins University researchers has discovered. Working with mice, the scientists found that the ipRGCs — an atypical type of photoreceptor in the retina — help detect contrast between light and dark, a crucial element in the formation of visual images. The key to the discovery is the fact that the cells express melanopsin, a type of photopigment that undergoes a chemical change when it absorbs light Continue reading
