How strong is the gravity on Mars?
The planet Mars shares numerous characteristics with our own. Both planets have roughly the same amount of land surface area, sustained polar caps, and both have a similar tilt in their rotational axes, affording ...
Laser sniffs out toxic gases from afar
Scientists have developed a way to sniff out tiny amounts of toxic gases—a whiff of nerve gas, for example, or a hint of a chemical spill—from up to one kilometer away.
"Weather bomb" is scary new name for common winter storm
A dramatically-named "weather bomb" exploded across the UK in the past week, bringing winds gusting up to 144mph on outlying islands.
Physicist demonstrates dictionary definition was dodgy
It is the defining moment that demonstrates a QUT physicist was correct in pointing out a 99-year-old mistake to one of the world's most authoritative dictionaries.
Mars' halcyon times may have been fleeting
Cold and dry today, Mars was previously warm and wet but possibly only at intervals, a study published on Sunday suggests.
Physicists surprised by disappearing and reappearing superconductivity in iron selenium chalcogenides
(PhysOrg.com) -- Superconductivity is a rare physical state in which matter is able to conduct electricity -- maintain a flow of electrons -- without any resistance. This phenomenon can only be found in certain ...
Astronomers solve temperature mystery of planetary atmosphere
(Phys.org) —An atmospheric peculiarity the Earth shares with Jupiter, Saturn, Uranus and Neptune is likely common to billions of planets, University of Washington astronomers have found, and knowing that ...
A curious cold layer in the atmosphere of Venus
(Phys.org)—Venus Express has spied a surprisingly cold region high in the planet's atmosphere that may be frigid enough for carbon dioxide to freeze out as ice or snow.
Probing hydrogen under extreme conditions
(Phys.org) -- How hydrogen--the most abundant element in the cosmos--responds to extremes of pressure and temperature is one of the major challenges in modern physical science. Moreover, knowledge gleaned ...
Researchers devise a way to measure volatile organic compound exchange in the atmosphere
Pressure transforms a semiconductor into a new state of matter
(Phys.org) —By applying pressure to a semiconductor, researchers have been able to transform a semiconductor into a "topological insulator" (TI), an intriguing state of matter in which a material's interior ...
Physicists discover mechanisms of wrinkle and crumple formation
Smooth wrinkles and sharply crumpled regions are familiar motifs in biological and synthetic sheets, such as plant leaves and crushed foils, say physicists Benny Davidovitch, Narayanan Menon and colleagues ...
Magnesium oxide: From Earth to super-Earth
The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors. New work from ...
New form of superhard carbon observed
An amorphous diamond one that lacks the crystalline structure of diamond, but is every bit as hard has been created by a Stanford-led team of researchers.
