LONDON: In a good news for protective parents, they can now limit the speed of their reckless kids' cars by using a new control key system to be available in the market soon. 

The system called MyKey, which will be on shelves in the UK from next month, interfaces with the computer systems on board its latest cars to place restrictions on drivers using the special keys. It works by recognizing different keys for the same car and then adjusting the vehicle settings according to the owner's requirements , with the capacity to limit the top speed to 128 kmph, the Daily Mail said. 

The limits are linked to the specific key, so parents concerned about their inexperienced children can limit top speed and stereo volume for youngsters while retaining full functionality for themselves. 

"MyKey allows parents to tailor vehicle performance and driver environment to suit individual users," the company said. 

"Permanent enabling of safety and driver aids and speed and audio limiting give parents greater control without impacting on young drivers' independence," it said. 

Manufacturers claim the MyKey system can also be programmed to alert the driver that fuel is running low.

Drug that can halt cancer spread

LONDON: Scientists have developed a new drug which they claim can put cancerous cells to sleep to stop them from multiplying. 

The drug called Aflibercept tricks tumours into becoming dormant by flipping molecular switches in the structure of the cancer so it cannot spread. 

Positive results are being seen already in the UK, where trials have seen patients enjoy a "significant" extension of life, the Daily Mail reported. More than 1,400 patients were involved in trials, with some participants with advanced bowel cancer who had already had chemotherapy prolonged life by two years. 

Scientists think the drug could be used across a range of different cancers in future studies. 

A report in the Journal of Clinical Oncology said Aflibercept had a 'statistically significant survival benefit' compared to conventional drug regimes treating bowel cancer that had spread after initial treatment. 

"The trial results were positive . Around 10,000 patients a year die from bowel cancer and most of them are having some form of chemotherapy so it is theoretically applicable to those," said Dr Rob Glynne Jones, Macmillan Clinical Lead for Gastrointestinal Cancer at Mount Vernon Hospital in Northwood, Middlesex, said. 

"I am sure this drug will have a research programme and they will be extending it to all other cancers. Maybe they will find other cancers where it may be more effective," Jones said. 

Aflibercept is administered as a 30-minute infusion alongside chemotherapy. It is available in the US, and European approval is expected soon, the paper said. 

Protein tied to breast cancer growth found 

Scientists have discovered a protein "partner" used by breast cancer cells to unlock genes needed for spreading the disease around the body. Researchers from the Johns Hopkins University found that "the protein JMJD2C is the key that opens up a whole suite of genes needed for tumours to grow and metastasize".

The structure and the growth of the Universe may be similar to that of human brain and the Internet, a new study has found.
Researchers found that the structure of the universe and the laws that govern its growth share more similarities than previously thought to the structure and growth of the human brain and other complex networks, such as the Internet or a social network of trust relationships between people.
"By no means do we claim that the universe is a global brain or a computer," said Dmitri Krioukov, co-author of the study from the University of California (UC), San Diego.

"But the discovered equivalence between the growth of the universe and complex networks strongly suggests that unexpectedly similar laws govern the dynamics of these very different complex systems," said Krioukov in a UC statement. Having the ability to predict – let alone trying to control – the dynamics of complex networks remains a central challenge throughout network science.
Structural and dynamical similarities among different real networks suggest that some universal laws might be in action, although the nature and common origin of such laws remain elusive.
By performing complex supercomputer simulations of the universe and using a variety of other calculations, researchers have now proven that the causal network representing the large-scale structure of space and time in our accelerating universe is a graph that shows remarkable similarity to many complex networks such as the Internet, social, or even biological networks.
"These findings have key implications for both network science and cosmology.
"We discovered that the large-scale growth dynamics of complex networks and causal networks are asymptotically (at large times) the same, explaining the structural similarity between these networks," noted Krioukov.
"This is a perfect example of interdisciplinary research combining math, physics, and computer science in totally unexpected ways.
"Who would have guessed that the emergence of our universe's four-dimensional spacetime from the quantum vacuum would have anything to do with the growth of the Internet? Causality is at the heart of both, so perhaps the similarity Krioukov and his collaborators found is to be expected." said San Diego Supercomputer Center, Director Michael Norman.
The network representing the structure of the universe is astronomically huge – in fact it can be infinite. But even if it is finite, researchers' best guess is that it is no smaller than 10250 atoms of space and time.
