World's most powerful digital camera opens eye, records first images in hunt for dark energy
Scientists in the international Dark Energy Survey collaboration announced this week that the Dark Energy Camera, the world's most powerful digital camera, has achieved first light. The camera is mounted on the Blanco telescope in Chile, and the first pictures of the southern sky were taken by the 570-megapixel camera on Sept. 12. (2012-09-17)

Univ. of Fla. engineer, students create glow-in-the-dark bicycle
Nighttime cyclists may soon have a dramatic safety improvement that's sure to get glowing reviews: a bike that glows from stem to stern, wheels included. Using the same technology that makes wristwatch faces light up in the dark, researchers at the University of Florida have created a bicycle with electro-luminescent panels on the frame and tire rim (2001-10-18)

Planck: final data from the mission lends support to the standard cosmological model
With its increased reliability and its data on the polarisation of relic radiation, the Planck mission corroborates the standard cosmological model with unrivalled precision for these parameters, even if some anomalies still remain. For this work the Planck consortium called upon some three hundred researchers, in particular from CNRS, CNES (the French national space agency), CEA (the French Alternative Energies and Atomic Energy Commission) and several universities in France. (2018-07-18)

Psychologists define the 'dark core of personality'
Egoism, Machiavellianism, narcissism, psychopathy, sadism, spitefulness are all traits that stand for the malevolent dark sides of human personality. Results from a recently published German-Danish research project show, these traits share a common 'dark core.' So, if you have one of these tendencies, you are also likely to have one or more of the others. (2018-09-26)

Hubble & Gaia accurately weigh the Milky Way
In a striking example of multi-mission astronomy, measurements from the NASA/ESA Hubble Space Telescope and the ESA Gaia mission have been combined to improve the estimate of the mass of our home galaxy the Milky Way: 1.5 trillion solar masses. (2019-03-07)

Dark energy may be vacuum
Researchers at the University of Copenhagen's Dark Cosmology Centre at the Niels Bohr Institute have brought us one step closer to understanding what the universe is made of. The new data shows that vacuum energy is the most likely cause and the expansion history of the universe can be explained by simply adding this constant background of acceleration into the normal theory of gravity.

International team of researchers redefines cosmic velocity web
The cosmic web -- the distribution of matter on the largest scales in the universe -- has usually been defined through the distribution of galaxies. Now, a new study by a team of astronomers from France, Israel and Hawaii demonstrates a novel approach. Instead of using galaxy positions, they mapped the motions of thousands of galaxies. (2017-08-14)

BPA exposure during pregnancy can alter circadian rhythms
Exposure to the widely used chemical bisphenol A (BPA) during pregnancy, even at levels lower than the regulated 'safe' human exposure level, can lead to changes in circadian rhythms, according to a mice study to be presented Monday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La. The researchers report these changes may be a contributing factor in hyperactivity seen in BPA-exposed mice. (2019-03-24)

Foodie calls: Dating for a free meal (rather than a relationship)
New psychology research reveals 23-33% of women in an online study say they've engaged in a 'foodie call,' where they set up a date for a free meal. These women score high on the 'dark triad' of personality traits as well. (2019-06-21)

The scaled king and his knight: 2 new giant bent-toed gecko species from New Guinea
The extremely complex geological history of New Guinea has allowed many of its animals and plants the chance to grow different enough to make a name for themselves. In the case of two newly described and unusually large gecko species -- only a noble name would do. The two new species, whose names respectively mean 'knight' and 'king', were discovered by a team led by Dr. Paul Oliver and are described in the open-access journal ZooKeys. (2016-02-10)

The smell of dark chocolate, demystified
Chocolate is one of the most-consumed treats around the world, and the smell alone is usually enough to evoke strong cravings from even the most disciplined eaters. Much like a fine wine, high-quality dark chocolate has a multi-layered scent and flavor, with notes of vanilla, banana or vinegar. Now, researchers report in ACS' Journal of Agricultural and Food Chemistry which substances -- and how much of them -- make up this heavenly aroma. (2019-05-08)

POLARBEAR seeks cosmic answers in microwave polarization
Based on measurements of B-mode polarization in the cosmic microwave background radiation, BICEP2 reported last March detection of gravitational waves caused by inflation in the early universe. The POLARBEAR experiment is studying this B-mode polarization to answer other questions: what is the overall structure of matter in the universe, what are the masses of neutrinos, and what is the nature of dark matter and dark energy. New data proves the feasibility of this approach. (2014-10-20)

Snapshot of cosmic burst of radio waves
A strange phenomenon has been observed by astronomers right as it was happening -- a 'fast radio burst.' The eruption is described as an extremely short, sharp flash of radio waves from an unknown source in the universe. The results have been published in the Monthly Notices of the Royal Astronomical Society. (2015-01-19)

Dartmouth researchers shed new light on dark energy, cosmic speed-up
In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion. While the findings don't explain the cosmic speed-up, they eliminate one provocative possibility that our planet, solar system and galaxy are at the center of the universe and that there is no dark energy. (2013-11-06)

Into the ice: Completing the IceCube Neutrino Observatory
With the sinking of the last of 86 strings carrying over 5,000 photodetectors a mile and a half deep in the Antarctic ice, IceCube, the world's most sensitive neutrino detector, is now complete. The electronics and packaging of the photodetectors, called Digital Optical Modules, were conceived, designed, and tested by scientists and engineers at the US Department of Energy's Lawrence Berkeley National Laboratory.

Origin of key cosmic explosions still a mystery
When a star explodes as a supernova, it shines so brightly that it can be seen from millions of light-years away. One particular supernova variety -- Type Ia -- brightens and dims so predictably that astronomers use them to measure the universe's expansion. The resulting discovery of dark energy and the accelerating universe rewrote our understanding of the cosmos. Yet the origin of these supernovae, which have proved so useful, remains unknown. (2010-07-12)

NASA satellites detect 'glow' of plankton in black waters
For the first time, scientists may now detect a phytoplankton bloom in its early stages by looking at its red (2004-08-31)

In powerful gamma-ray bursts, neutrinos may fly out first, scientists say
The most powerful explosions in the universe, gamma-ray bursts, may come with a 10-second warning: an equally violent burst of ultra-high-energy particles called neutrinos. These nearly massless particles, which, can penetrate regions of space that choke gamma rays and other forms of light, may carry details of the very first stars and may help scientists count the number of massive stars that have collapsed to form black holes. (2001-11-05)

Scientists shed light on processes behind age-related decline in brain structures
Ageing can cause damage to support cells in the white matter, which in turn may lead to damage in the grey matter of the hippocampus, finds a new study by Cardiff University. (2019-01-31)

Seeing beyond the gray areas: New tool uncovers the importance of the brain's white matter
Up until now there has been very little known about the brain's white matter-a new tool is about to change that. (2006-06-08)
