Details of calcium ‘safety-valve’ in cells explained

Details of calcium ‘safety-valve’ in cells explained

Sometimes a cell has to die — when it’s done with its job or inflicted with injury that could otherwise harm an organism. Conversely, cells that refuse to die when expected can lead to cancer. So scientists interested in fighting cancer have been keenly interested in learning the details of “programmed cell death.” They want to understand what happens when this process goes awry and identify new targets for anticancer drugs.

New targets that could increase effectiveness, reduce side effects in breast cancer treatments

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have found new targets for potential intervention in breast cancer. Continue reading

Molecular secret of short, intense workouts clarified

Molecular secret of short, intense workouts clarified

In the last few years, the benefits of short, intense workouts have been extolled by both researchers and exercise fans as something of a metabolic panacea capable of providing greater overall fitness, better blood sugar control and weight reduction — all of it in periods as short as seven minutes a few times a week. Now, in a new study, scientists from the Florida campus of The Scripps Research Institute (TSRI) confirm that there is something molecularly unique about intense exercise: the activation of a single protein.

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
