"Researchers failed to find evidence of so-called "supersymmetric" particles, which many physicists had hoped would plug holes in the current theory.
Theorists working in the field have told BBC News that they may have to come up with a completely new idea.
Data were presented at the Lepton Photon science meeting in Mumbai."
"Obesity has a greater impact on the blood pressure of teenage girls than on teenage boys, a US study has suggested.
High blood pressure is a risk factor for heart disease and stroke in later life.
The study of 1,700 teenagers, presented to the American Physiological Society conference, found girls had three times the risk of higher blood pressure."
"Most massive galaxies, including our own Milky Way, are thought to harbour supermassive black holes at their centres.
But these newly discovered black holes are much bigger than would be predicted by extrapolating from observations from their host galaxies.
This suggests that the factors influencing the growth of the largest galaxies and their black holes differ from those influencing smaller galaxies.
The findings come from observations of two nearby galaxies: NGC 3842 and NGC 4889."
"Every year, about 1,000 women in the UK suffer from what is called postpartum psychosis. Most of them will need several weeks in hospital to help them recover but, because of the stigma of mental illness, it is not often talked about. "
"A team at the Carnegie Institution for Science subjected the material to pressures up to 1.4 million times atmospheric pressure at sea level, and temperatures up to 2,200C.
They found that it pulls off the trick of changing its electrical properties without any shifting of shape - it can be an insulator or conductor depending just on temperature and pressure.
Combined with computer simulations of just what was going on with the material's electrons, the group claim that the results show a new type of metallisation.
"At high temperatures, the atoms in iron oxide crystals are arranged with the same structure as common table salt," said Ronald Cohen, a co-author of the study. "Just like table salt, iron oxide at ambient conditions is a good insulator-it does not conduct electricity.""
"Todd Rider, a research scientist at the Massachusetts Institute of Technology, is developing an antiviral drug called Draco, which has proven successful against all 15 viruses to which it has been applied in lab trials with human tissue and mice.
These include the common cold, H1N1 or swine flu, a polio virus, dengue fever and the notorious and fatal Ebola virus.
To produce it, Mr Rider took an unusual approach, "wiring together" two natural proteins - one that detects virus entry, and another that acts as a suicide switch that kills the infected cell."
"Claims that the costs of wind farms and other low-carbon technology will lead to sharp rises in fuel bills are wrong, government advisers say.
The Committee on Climate Change (CCC) says increases in bills over the past few years have been largely due to higher wholesale gas costs."
"Coffee addicts have an excuse for blaming their genes.
According to new research, genetic factors could explain why some people consume large amounts of caffeine.
US researchers scanned genetic variations in over 40,000 individuals to search for links with high caffeine intake."
"Nearly 20% of women in the US are raped or suffer attempted rape at some point in their lives, a US study says.
Even more women, estimated at 25%, have been attacked by a partner or husband, the Centers for Disease Control said."
"They think they are of a kind never before discovered.
The well-preserved organisms from the Ordovician period, which began about 495m years ago, lived in what is now the town of Llandrindod Wells, which was partially under water.
Scientists believe they shed new light on how ocean communities have evolved."
"The onset of wrinkles, muscle wasting and cataracts has been delayed and even eliminated in mice, say researchers in the US.
It was done by "flushing out" retired cells that had stopped dividing. They accumulate naturally with age.
The scientists believe their findings could eventually "really have an impact" in the care of the elderly."
"The team from the French National Institute for Agricultural Research (INRA) surveyed the composition of plant species within five-metre SGS in 10 fields and found the set-aside land resulted in a "sharp decrease" in the number of weeds encroaching into the cropped area."
"Scientists say they can now explain the existence of what are perhaps Earth's most extraordinary mountains.
The Gamburtsevs are the size of the European Alps and yet they are totally buried beneath the Antarctic ice."
"A US-based team of scientists claims to have invented a material that releases over two weeks of night-vision light after just one minute's exposure to the sun.
The University of Georgia team says the near-infrared emitting substance could offer the military "secret" illumination at nighttime."
"Now a different team at the same lab reports findings that, they say, cast doubt on that surprising result.
The Icarus team at the Icarus experiment says that because the neutrinos sent from Cern do not appear to lose energy on their journey, they must not have exceeded the speed of light along the way."
"Scientists in Russia have grown plants from fruit stored away in permafrost by squirrels over 30,000 years ago.
The fruit was found in the banks of the Kolyma River in Siberia, a top site for people looking for mammoth bones."
"Harps employs an indirect method of detection that infers the existence of orbiting planets from the way their gravity makes a parent star appear to twitch in its motion across the sky.
"Our new observations with Harps mean that about 40% of all red dwarf stars have a super-Earth orbiting in the habitable zone where liquid water can exist on the surface of the planet," said team leader Xavier Bonfils from the Observatoire des Sciences de l'Univers de Grenoble, France.
"Because red dwarfs are so common - there are about 160 billion of them in the Milky Way - this leads us to the astonishing result that there are tens of billions of these planets in our galaxy alone.""
"Anatomists such as Prof Peter Abrahams believe that Leonardo's work was some 300 years ahead of its time, and in some ways superior to what was available in the 19th Century Gray's Anatomy.
They say it is only recently with 3D, digital technology and moving images that we have been able to take a decisive step beyond what Leonardo's hand and eye were able to achieve."
