New research by the Gladstone Institutes of Cardiovascular Disease (GICD) and the University of California, San Francisco (UCSF), has revealed the genetic determinants of fat storage in cells, which may lead to a new understanding of and potential treatments for obesity, diabetes, and heart disease. While scientists have long understood that lipid droplets contribute to fat build up in cells, the genes involved in droplet biology have been a focus of extensive research.

In a study published in Nature, scientists in the laboratories of Drs. Robert V. Farese, Jr., of Gladstone and UCSF, and Peter Walter, of UCSF, devised a genetic screen to identify genes responsible for fat storage in cell of fruit flies, and potentially other species.

New research in the Society of Chemical Industry’s Journal of the Science of Food and Agriculture shows that oregano oil works as well as synthetic insecticides to combat infestation by a common beetle, Rhizoppertha dominica, found in stored cereals.

Not only does oregano oil work as well as synthetic versions but it has none of the associated side effects of synthetic insecticides on the environment.

Growing resistance to synthetic insecticides combined with potential environmental damage and new government directives on changes to the way chemicals are registered means that scientists are increasingly looking at natural alternatives that can be produced in the large scale quantities needed for agricultural industry use.

Scientists have reported evidence of a large ornithopod dinosaur, as well as a herd of 11 sauropods, walking along a Mesozoic coastal mudflat in what is now the Republic of Yemen - the first dinosaur tracks on the Arabian Peninsula.

The finding also is an excellent example of dinosaur herding behavior, the researchers report. The site preserved footprints of 11 small and large sauropods — long-necked, herbivorous dinosaurs that lived in the Jurassic and Cretaceous periods — traveling together at the same speed.

“No dinosaur trackways had been found in this area previously. It’s really a blank spot on the map,” said Anne Schulp of the Maastricht Museum of Natural History in The Netherlands. He conducted the study with Ohio University paleontologist Nancy Stevens and Mohammed Al-Wosabi of Sana’a University in Yemen.

In the perpetual fight over evolution in public schools, there is good news and bad news. The good news is that supporters of science education have largely been successful in shutting down creationist attempts to undermine evolution through state legislatures and state school boards. While there is still mischief going on in many state legislatures, these efforts rarely go anywhere, thanks to vigilance by supporters of good science education. An essay in PLoS Biology today argues that, at the state level, things are going well:

At this time, not a single state uses its content standards to explicitly promote ID or creationism. School boards are monitored by organizations like the National Center for Science Education, by state academies of science, and by local scientific and professional organizations. As a result, few state school boards can formally consider measures like the one adopted in Dover without scrutiny and challenge from organizations representing the scientific profession.

But here comes the bad news:

There are many reasons to believe that scientists are winning in the courts, but losing in the classroom.

A segment on ABC’s Good Morning America May 19 caught my attention, so much so that I spent a good chunk of time attempting to find research to back up the claims. The idea itself seems to be obvious – if you have a neurological disorder affecting your brain, you should examine the brain in order to figure out exactly what’s going on to figure out how to best treat the problem, right? I am not a neurologist, so my thinking could be flawed. A comment by the doctor featured in the segment made sense to me, though: diagnosing children with behavioral disorders like ADHD and autism without looking at their brains is like trying to diagnose heart problems without actually looking at the heart.

Sensitivity to reward loss is an indicator of animal emotion and welfare, say scientists at Bristol University Veterinary School.

Rats housed in standard conditions show a stronger response to the loss of an expected food reward than those housed in enriched conditions, perhaps indicating a more negative emotional state, according to the new research by published in this week's issue of Royal Society Biology Letters.

The researchers have developed a new approach to the measurement of animal emotional states based on findings from human psychology that emotions affect information processing. In general, people are more sensitive to reward losses than gains, but depressed people are particularly sensitive to losses. The researchers wanted to know whether animals' sensitivity to reward loss might also be related to their emotional state.

Discovered nearly 20 years ago, carbon nanotubes have been described as the wonder material of the 21st Century. Light as plastic and stronger that steel, they are being developed for use in new drugs, energy-efficient batteries and futuristic electronics. A major study published today suggests some forms of carbon nanotubes, the poster children for the “nanotechnology revolution”, could be as harmful as asbestos if inhaled in sufficient quantities.

The study used established methods to see if specific types of nanotubes have the potential to cause mesothelioma — a cancer of the lung lining that can take 30-40 years to appear following exposure. The results show that long, thin multi-walled carbon nanotubes that look like asbestos fibers, behave like asbestos fibers.

Since their discovery, questions have been raised about whether some of these nanoscale materials may cause harm and undermine a nascent market for all types of carbon nanotubes, including multi- and single-walled carbon nanotubes. Leading forecasting firms say sales of all nanotubes could reach $2 billion annually within the next four to seven years, according to an article in the U.S. publication Chemical & Engineering News.

Researchers at the Peninsula Medical School in the South West of England, University College London, the San Raffaele Scientific Institute in Milan and Cancer Research UK, have for the first time identified a protein that is key to the regeneration of damage in the peripheral nervous system and which could with further research lead to understanding diseases of our peripheral nervous systems and provide clues to methods of repairing damage in the central nervous system, according to a paper published this week in the Journal of Cell Biology.

The team looked at a protein called c-Jun, a transcription factor that regulates the expression of other genes. They found that the c-Jun protein plays a vital role in the regulating the plasticity of Schwann cells which is vital for the way in which the peripheral nervous system regenerates and repairs itself after injury.

Each day we risk exposure to around 70,000 chemicals. In food packaging or even the air we breathe, contact with potentially-toxic substances could be affecting our health, including fertility.

The Reproductive Effects of Environmental Chemicals in Females Consortium (REEF) is one of the first studies tackling the effect of environmental chemicals on female mammals. REEF will receive a total of £2.4m in funding from the EU.

Dr Richard Lea and Dr Kevin Sinclair at The University of Nottingham will receive a £500,000 grant for their work researching how these chemicals impact on mammalian fertility. Dr Lea and Dr Sinclair will study the impact of low levels of environmental chemicals on sheep foetuses in the womb. The specific chemicals to be studied are found in human sewage sludge which is frequently spread on fields where sheep graze prior to entering the human food chain.

Titanium is the lightweight metal of choice for many applications and a non-melt consolidation process being developed by Oak Ridge National Laboratory may make it cheap enough to bulletproof your Prius. Or a military vehicle, if you want to be predictable.

The new processing technique could reduce the amount of energy required and the cost to make titanium parts from powders by up to 50 percent, making it feasible to use titanium alloys for brake rotors, artificial joint replacements and armor for vehicles.

The lightweight titanium alloy also improves the operation of the door and increases mobility of the vehicle, making it even more useful to the military.
