Despite much research, the genetic causes why animals have such different longevities remain largely unknown, much because so many factors act on ageing that isolating the effect of a single gene is almost impossible.
But now, a study just published in the journal AGE might help to change that as researchers Pedro Magalhães and Yang Li from the Institute of Integrative Biology, at the UK University of Liverpool, unveil a new method that has already help them to identify several proteins involved in DNA-repair and in the recycling of abnormal molecules as being linked to longevity.
Noise levels, fine particulate matter that leads to smog and traffic volumes are a big concern to urban planners and residents now but they will be even bigger issues in the 'city of tomorrow'.
Three-dimensional tools will soon make it easier to simulate those issues: as the user virtually moves through his city, the corresponding data are displayed as green, yellow or red dots.
A new study estimates that more than 260,000 dogs and cats were sent to UK rescue shelters in 2009, the first full year of the worldwide recession.
Dogs and cats are popular pets in the UK and two of the authors of the new estimate study, Dr. Jane Murray and Professor Tim Gruffydd-Jones, having previously estimated the owned cat and dog populations at approximately 10.3 and 10.5 million respectively.
Astronomers believe they have found the answer to the mystery of a powerful ‘superwind’ which causes the death of stars.
Stars like our own Sun end their lives with a ‘superwind’ 100 million times stronger than the solar wind, which occurs over a period of 10,000 years, and removes as much as half the mass of the star. At the end, only a dying and fading remnant of the star remain.
Not to worry. The Sun won't begin to throw out those gases for around five billion years.
100 years yesterday, the RMS Titanic struck an iceberg while crossing the North Atlantic and sank, killing over 1500 passengers and crew.
Cyberbullies don't feel like they are the same as physical bullies. Some new research agrees, and for that reason anti-bullying campaigns need to be optimized for the Internet.
Traditional bullying, the 'schoolyard' kind of bullying, is often associated with three main characteristics: a power differential between bully and victim, proactive targeting of a victim and ongoing aggression. The Internet is the great equalizer. Traditional power differentials, like size and popularity, don't apply as commonly in cyberbullying and the lines between victim and aggressor are more blurred; it is not unusual for an individual to act in all capacities - bully, victim, and witness - online.
The Trefael Stone is an ancient monument in south-west Wales.
Men and women of good conscience cannot sit silently by and allow these things to happen. This is abuse and torture and, still, people support these. Still the Massachusett's State House supports it. Believe it or not, some parents of residents continue to speak out in favor of the use of these shocks.
On April 5, 2010, the sun spewed a two million-mile-per-hour stream of charged particles toward the magnetosphere, the invisible magnetic fields surrounding Earth.
As the particles interacted with the magnetic fields, the incoming stream of energy caused stormy conditions near Earth. Some scientists believe that it was this solar storm that interfered with commands to a communications satellite, Galaxy-15, which subsequently foundered and drifted, taking almost a year to return to its station.
A new observatory, the Atacama Large Millimeter/submillimeter Array (ALMA), is still under construction but it has already given astronomers a major breakthrough in understanding a nearby planetary system and provided valuable clues about how such systems form and evolve.
Astronomers using ALMA have discovered that planets orbiting the star Fomalhaut are much smaller than originally thought.
