Landmark study proves that magnets can control heat and sound

Landmark study proves that magnets can control heat and sound | The Daily Organic | Scoop.it

Researchers at The Ohio State University have discovered how to control heat with a magnetic field.

 

The study is the first ever to prove that acoustic phonons - the elemental particles that transmit both heat and sound - have magnetic properties.

"This adds a new dimension to our understanding of acoustic waves," said Joseph Heremans, Ohio Eminent Scholar in Nanotechnology and professor of mechanical engineering at Ohio State. "We've shown that we can steer heat magnetically. With a strong enough magnetic field, we should be able to steer sound waves, too."

Introducing the multi-tasking nanoparticle for diagnostic and therapeutic applications

Introducing the multi-tasking nanoparticle for diagnostic and therapeutic applications | The Daily Organic | Scoop.it

Kit Lam and colleagues from UC Davis and other institutions have created dynamic nanoparticles (NPs) that could provide an arsenal of applications to diagnose and treat cancer. Built on an easy-to-make polymer, these particles can be used as contrast agents to light up tumors for MRI and PET scans or deliver chemo and other therapies to destroy tumors. In addition, the particles are biocompatible and have shown no toxicity. The study was published online today in Nature Communications.

 

“These are amazingly useful particles,” noted co-first author Yuanpei Li, a research faculty member in the Lam laboratory. “As a contrast agent, they make tumors easier to see on MRI and other scans. We can also use them as vehicles to deliver chemotherapy directly to tumors; apply light to make the nanoparticles release singlet oxygen (photodynamic therapy) or use a laser to heat them (photothermal therapy) – all proven ways to destroy tumors.”


Jessica Tucker, program director of Drug and Gene Delivery and Devices at the National Institute of Biomedical Imaging and Bioengineering, which is part of the National Institutes of Health, said the approach outlined in the study has the ability to combine both imaging and therapeutic applications in a single platform, which has been difficult to achieve, especially in an organic, and therefore biocompatible, vehicle.

 

"This is especially valuable in cancer treatment, where targeted treatment to tumor cells, and the reduction of lethal effects in normal cells, is so critical,” she added.

 

 Though not the first nanoparticles, these may be the most versatile. Other particles are good at some tasks but not others. Non-organic particles, such as quantum dots or gold-based materials, work well as diagnostic tools but have safety issues. Organic probes are biocompatible and can deliver drugs but lack imaging or phototherapy applications.


Built on a porphyrin/cholic acid polymer, the nanoparticles are simple to make and perform well in the body. Porphyrins are common organic compounds. Cholic acid is produced by the liver.


To further stabilize the particles, the researchers added the amino acid cysteine (creating CNPs), which prevents them from prematurely releasing their therapeutic payload when exposed to blood proteins and other barriers. At 32 nanometers, CNPs are ideally sized to penetrate tumors, accumulating among cancer cells while sparing healthy tissue.


In the study, the team tested the nanoparticles, both in vitro and in vivo, for a wide range of tasks. On the therapeutic side, CNPs effectively transported anti-cancer drugs, such as doxorubicin. Even when kept in blood for many hours, CNPs only released small amounts of the drug; however, when exposed to light or agents such as glutathione, they readily released their payloads. The ability to precisely control chemotherapy release inside tumors could greatly reduce toxicity. CNPs carrying doxorubicin provided excellent cancer control in animals, with minimal side effects.

Scientists watch bioengineered self-healing muscle tissue grow within a mouse

Scientists watch bioengineered self-healing muscle tissue grow within a mouse | The Daily Organic | Scoop.it

The living skeletal muscle tissue grown by Duke University researchers is 10 times stronger than any previously bioengineered muscles. Not only does it contract as strongly and as rapidly as the real thing, but it is also capable of self-healing, both in the lab and after implantation into an animal. This has been proven beyond doubt through a novel approach that involves peeking at the growing muscle tissue through a glass window in the back of a living mouse.

UN Report Promotes Democratic Control of Food and an End to Corporate Domination

UN Report Promotes Democratic Control of Food and an End to Corporate Domination | The Daily Organic | Scoop.it

The world’s food system is controlled by a handful of giant corporations, the majority of which are based in the U.S., such as ConAgra, Cargill and PepsiCo. These companies are a bottleneck through which most of the world’s food is forced, in order to feed most of the world’s people.

 

Not only is this method environmentally unsustainable given its overreliance on chemical fertilizers, pesticides and fossil fuels, but it is also inefficient at actually feeding people.

"Good" gut microbes revealed as the key to dark chocolate's health benefits

"Good" gut microbes revealed as the key to dark chocolate's health benefits | The Daily Organic | Scoop.it

It has long been known that eating chocolate, particularly dark chocolate, has numerous health benefits. Although various studies have backed this up, the exact reason as to why this is so has remained a mystery. Now researchers from Louisiana State University have provided the answer – gut microbes.

 

Presenting their findings at the 27th National Meeting & Exposition of the American Chemical Society (ACS), the researchers revealed that, unlike so-called "bad" bacteria in the gut, such as some Clostridia and some E. coli, that are associated with inflammation and can cause gas, bloating, diarrhea and constipation, "good" bacteria, such as Bifidobacterium and lactic acid bacteria, feed on dark chocolate to produce anti-inflammatory compounds.

Tomatoes linked with fighting cancer

Tomatoes linked with fighting cancer | The Daily Organic | Scoop.it

Eating tomatoes may lower the risk of prostate cancer, research suggests.

 

Men who consume more than 10 portions of tomatoes each week reduce their risk by about 20%, according to a UK study.

 

Prostate cancer is the second most common cancer in men worldwide, with 35,000 new cases and around 10,000 deaths in the UK every year.

Cancer experts recommend eating a balanced diet which is high in fruit and vegetables and low in red and processed meat, fat and salt.

 

Men should still eat a wide variety of fruits and vegetables, maintain a healthy weight and stay active” - Vanessa Er - Bristol University

 

The Bristol team analysed the diets and lifestyles of around 20,000 British men aged between 50 and 69.

WTF is Oil Pulling + Why I’m Hooked

WTF is Oil Pulling + Why I’m Hooked | The Daily Organic | Scoop.it
Check out my latest health obsession- oil pulling. This ancient Indian practice will naturally change your overall dental health & much more.

 

Oil pulling has been around for years, which makes me mad I’ve only just found out about it. It’s an ancient Ayurvedic technique that basically involves you swishing oil in your mouth for 20 minutes (no more no less) to help improve your oral & overall health. The idea behind it is pretty simple stupid- the oil is “sticky” and when you swish it around in your mouth bacteria gets stuck in the oil & dissolves.

 

It’s easy to do. Pick an oil, you can use ORGANIC coconut oilor any other vegetable based oil (Sesame/ Sunflower/ or Olive).

Compound in fruits and vegetables prevents symptoms of Alzheimer's disease in mice | The Daily Organic | Scoop.it

Alzheimer's disease represents the most common form of dementia, with the early stages of the disease generally characterized with short term memory loss and learning difficulties that increase in severity as the patient progresses in age.

 

Scientists at the Salk Institute for Biological Studies, California, have discovered that with regular treatments of the antioxidant fisetin, they were able to prevent memory loss in mice with genetic mutations linked to Alzheimer's.
