Some dinosaurs were really huge. And now we may have a better way to estimate just how heavy these giants were. Researchers have developed a method to weigh dinosaurs, based on laser scans of their skeletons.

The surface waters of the Arctic Ocean may be releasing "significant" amounts of methane into the atmosphere, researchers reported yesterday in the journal Nature Geoscience . [More]

It’s tough to pick a familiar face out of a crowd--but focusing on a known voice in a noisy room is easy. And a new study scanned volunteers’ brains to look at how we solve the so-called cocktail party problem.

In the hostile environment of a bubbling volcanic hot spring, a team of researchers at Portland State University in Oregon has discovered a new viral genome that seems to be the product of recombination between a DNA virus and an RNA virus -- a natural chimaera not seen before. Their findings

Scientists have taken an important step forward in developing a new material using nano-sized magnets that could ultimately lead to new types of electronic devices, with greater capacity than is currently feasible, in a study published today in the journal Science.

Autonomous University of Barcelona researchers, in collaboration with an experimental group from the Academy of Sciences of Slovakia, have created a cylinder which hides contents and makes them invisible to magnetic fields. The device was built using superconductor and ferromagnetic materials available on the market. The invention is published this week in the journal Science.

A clock accurate to within a tenth of a second over 14 billion years – the age of the universe – is the goal of research being reported this week by scientists from three different institutions. To be published in the journal Physical Review Letters, the research provides the blueprint for a nuclear clock that would get its extreme accuracy from the nucleus of a single thorium ion.

It sounds like the premise for a bad police drama, maybe NYPD Chimp. But scientists have found that high-ranking chimpanzees can act like cops: intervening to settle public disputes. The study appears in the journal Public Library of Science ONE

(PhysOrg.com) -- Just as NASA engineers test new rocket designs in computer studies before committing themselves to full prototypes, so physicists will often model matter under various circumstances to see whether something new appears. This is especially true of atomtronics, a relatively new science devoted to creating artificial tailored materials consisting of neutral atoms held in an array with laser beams, or atoms moving along a desired track under electric or magnetic influence. A new study shows how a simple "joystick" consisting of an adjustable magnetic field can create several new phases of atomtronic matter, several of them never seen before.

Ironing increases the humidity of a piece of cloth by injecting water vapor in the form of steam. But how does the vapor affect the fabric? Until now, it was thought that its only effect was to soften the fibers

(PhysOrg.com) -- Magnetic resonance imaging (MRI) on the nanoscale and the ever-elusive quantum computer are among the advancements edging closer toward the realm of possibility, and a new study co-authored by a UC Santa Barbara researcher may give both an extra nudge. The findings appear today in Science Express, an online version of the journal Science.

A study in the journal of the American Medical Association reveals a dangerous difference in the symptoms men and women experience during a heart attack. Dr. Jon LaPook reports.

A new theory developed by Prof Gerrit van der Laan, from the Science & Technology Facilities Council (STFC) and Diamond Light Source, and published this week in the journal Physical Review Letters, provides a powerful sum rule that scientists can use to explore the properties of novel materials, such as those used for spintronics devices.

Top-heavy structures are more likely to maintain their balance while hovering in the air than are those that bear a lower center of gravity, researchers at New York University's Courant Institute of Mathematical Sciences and Department of Physics have found.

In the latest issue of the journal, "Nature," a pediatrician brands sugar a "toxin" that should be regulated like alcohol. CBS News correspondent Lee Cowan reports.
