Fermi finds a 'transformer' pulsar
(Phys.org) —In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at ...
Law of physics governs airplane evolution
Researchers believe they now know why the supersonic trans-Atlantic Concorde aircraft went the way of the dodo—it hit an evolutionary cul-de-sac.
Creating optical cables out of thin air
Imagine being able to instantaneously run an optical cable or fiber to any point on earth, or even into space. That's what Howard Milchberg, professor of physics and electrical and computer engineering at ...
Self-cooling solar cells boost power, last longer
Scientists may have overcome one of the major hurdles in developing high-efficiency, long-lasting solar cells—keeping them cool, even in the blistering heat of the noonday Sun.
Highly efficient nanoparticles could bring down the cost of fuel cells
(Phys.org) —Fuel cells are a promising, non-polluting way to power cars, but their platinum catalysts are so expensive that there's no way current technology could be economically scaled up for widespread ...
Squink personal factory aims to make circuit prototyping easy
Transiting exoplanet with longest known year
Astronomers have discovered a transiting exoplanet with the longest known year. Kepler-421b circles its star once every 704 days. In comparison, Mars orbits our Sun once every 780 days. Most of the 1,800-plus ...
Carbyne morphs when stretched: Calculations show carbon-atom chain would go metal to semiconductor
(Phys.org) —Applying just the right amount of tension to a chain of carbon atoms can turn it from a metallic conductor to an insulator, according to Rice University scientists.
Researchers figure out how oddly shaped sandstone landform structures come about
Material generates steam under solar illumination
A new material structure developed at MIT generates steam by soaking up the sun.
Nano-scale gold particles are good candidates for drug delivery
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.
Mysterious dance of dwarfs may force a cosmic rethink
(Phys.org) —The discovery that many small galaxies throughout the universe do not 'swarm' around larger ones like bees do but 'dance' in orderly disc-shaped orbits is a challenge to our understanding of ...
Tiny laser sensor heightens bomb detection sensitivity
New technology under development at the University of California, Berkeley, could soon give bomb-sniffing dogs some serious competition.
A noble gas cage: New material traps gases from nuclear fuel better
When nuclear fuel gets recycled, the process releases radioactive krypton and xenon gases. Naturally occurring uranium in rock contaminates basements with the related gas radon. A new porous material called ...
