GM tomatoes and helpful bacteria claimed to lower cholesterol

Atherosclerosis, more commonly known as hardening of the arteries, can have very serious consequences such as heart attacks and strokes. While there are medications that remove some of the offending plaque from the inside of the affected arteries, not everyone wants to take drugs unless absolutely necessary. Lifestyle improvements can certainly help, but soon two other options may be available – probiotics and genetically-engineered tomatoes. Read More

Neurological discovery could lead to machines that speak for the speechless

Recently, scientists unlocked the code used by neurons in the retina for sending visual data to the brain. This allowed them to create a device that restored almost-normal vision to blind mice. Now, another group of scientists has announced that they have determined the brain’s code for pronouncing vowels, and they believe that their discovery could lead to machines that speak for people who are physically unable to do so.

Earliest spiral galaxy ever observed puzzles astronomers

When astronomers used the Hubble Space Telescope to scout a remote patch of the sky and investigate the early stages of galaxy formation, they stumbled upon something which they did not expect. They realized that the distant spiral galaxy BX422, appearing to us as it was only three billion years after the Big Bang, seems to be uncharacteristically well-formed for its young age. By studying its features, which are in direct contrast with our current knowledge of galaxy formation, scientists hope to shed more light on how spiral galaxies – including our own – are formed.

NASA’s Dawn spacecraft unlocks secrets of giant asteroid

After becoming the first probe to enter orbit around an object in the main asteroid belt between Mars and Jupiter in July 2011, NASA’s Dawn spacecraft has spent the last 10 months orbiting said object - the giant asteroid Vesta. During that period it has captured more than 20,000 images of Vesta and a multitude of data from different wavelengths of radiation. What it reveals is an asteroid that in many ways shares more in common with a small planet or Earth’s moon than it does with another asteroid. Read More

Engineered cells seek out and kill HIV in living organisms

Although there is currently no cure for HIV, the body does already contain cells that fight the virus – the problem is, there just aren’t enough of them to completely get rid of it. In 2009, scientists at UCLA performed a proof-of-concept experiment, in which they were able to grow these CD8 cytotoxic T lymphocytes (better known as infection-fighting “T cells”) from genetically engineered human stem cells. Now, in a subsequent study, they have demonstrated that these engineered cells can seek out and kill HIV-infected cells in a living organism. Read More

Researchers generate liquid fuel using electricity

While electric vehicles have come a long way in the past decade, they still have many disadvantages when compared to internal combustion engine-driven vehicles. The lithium-ion batteries that power electric vehicles have a much lower energy storage density when compared to liquid fuel, they take longer to “refuel,” and they lack the supporting infrastructure that has built up around conventional vehicles over the past century. Now researchers at the UCLA Henry Samueli School of Engineering and Applied Science have developed a process that could allow liquid fuel to be produced using solar generated electricity. Read More

New device is more effective and safer than FDA-approved treatment for acute stroke patients

A new approach to stroke treatment initially developed by Dr. Jeffrey Saver's group at the UCLA Stroke Center combines the ability to restore circulation and remove clots using only a single device ... and it's showing significant promise in trials. In a study comparing the Covidien Solitaire FR Revascularization Device with the FDA-approved Merci Retriever, the device successfully and safely treated roughly 60 percent of stroke patients, compared to roughly 30 percent when the Merci Retriever was used.

Phone-based scanner detects harmful bacteria

Soon, you may never have to play Russian roulette with potato salad again. Instead of just hoping that E. coli bacteria aren't present in your foods or drinks, you could instead use your mobile phone to find out for sure. That phone would have to be equipped with a bacteria-detecting scanner, which researchers from the UCLA Henry Samueli School of Engineering and Applied Science recently created - in a prototype version, for now.

Human embryonic stem cell transplants found to improve vision in clinical trials

UCLA researchers are reporting a milestone in the therapeutic use of stem cells after two legally blind patients who received transplants of specialized retinal cells derived from human embryonic stem cells reported a modest improvement in their vision. Monitoring of the patients’ progress over a four month period also found no safety concerns, signs of rejection or abnormal cell growth. The researchers are claiming that the success of the procedure could pave the way for a new therapy to treat eye diseases. Read More
