Washington, Dec 04 - A new study has found that listeners can not only distinguish the age and gender but also can accurately determine the relative heights of speakers just by listening to them talk.
The key clue may be contained in a particular type of sound produced in the lower airways of the lungs, known as a subglottal resonance.
"The best way to think about subglottal resonances is to imagine blowing into a glass bottle partially full with liquid: the less liquid in the bottle, the lower the sound," John Morton, a psychologist at Washington University in St. Louis explained.
Washington, Dec. 4 - Astronomers using NASA's Wide-field Infrared Survey Explorer (WISE) have spotted what appears to be two supermassive black holes, at the heart of a remote galaxy, circling each other like dance partners.
Follow-up observations with the Australian Telescope Compact Array near Narrabri, Australia, and the Gemini South telescope in Chile revealed unusual features in the galaxy, including a lumpy jet thought to be the result of one black hole causing the jet of the other to sway.
Washington, Dec. 4 - Researchers have warned that the world's largest tropical desert, the Sahara, has suffered a catastrophic collapse of its wildlife populations.
The study by more than 40 authors representing 28 scientific organizations assessed 14 desert species and found that a shocking half of those are regionally extinct or confined to one percent or less of their historical range.
A chronic lack of studies across the region due to past and ongoing insecurity makes it difficult to be certain of the causes of these declines, although overhunting is likely to have played a role.
Washington, Dec. 4 - Researchers have shown that the subsurface ocean on Jupiter's moon Europa may have deep currents and circulation patterns with heat and energy transfers capable of sustaining biological life.
Scientists believe Europa is one of the planetary bodies in our solar system most likely to have conditions that could sustain life, an idea reinforced by magnetometer readings from the Galileo spacecraft detecting signs of a salty, global ocean below the moon's icy shell.
Regions of disrupted ice on the surface, known as chaos terrains, are one of Europa's most prominent features.
Washington, Dec. 4 - Researchers using NASA's Hubble Space Telescope have found faint signatures of water in the atmospheres of five distant planets.
The five planets-WASP-17b, HD209458b, WASP-12b, WASP-19b and XO-1b-orbit nearby stars.
The strengths of their water signatures varied. WASP-17b, a planet with an especially puffed-up atmosphere, and HD209458b had the strongest signals.
The signatures for the other three planets, WASP-12b, WASP-19b and XO-1b, also are consistent with water.
Washington, Dec 4 - US space company SpaceX launched their first commercial satellite from Florida, in a mission that will usher in a newcomer in the global launch services industry.
The Falcon 9 rocket launched the commercial SES-8 telecommunications satellite for satellite services provider SES from Cape Canaveral Air Force Station, Florida Tuesday, reported Xinhua citing the California-based company's live webcast.
The launch was originally set to take place last week, but was delayed twice due to technical and engine problems.
Washington, Dec 03 - Up till now it was unknown to researchers whether ingested plastic transfers chemical additives or pollutants to wildlife, but a new study has shown that toxic concentrations of pollutants and additives enter the tissue of animals that have eaten microplastic.
Lead author Mark Anthony Browne, a postdoctoral fellow at NCEAS, had two objectives when the study commenced: to look at whether chemicals from microplastic move into the tissues of organisms; and to determine any impacts on the health and the functions that sustain biodiversity.
Washington, December 3 - A new brain connectivity study has found striking differences in the neural wiring of men and women which justifies some of the commonly-held beliefs about their behavior.
The Penn Medicine brain imaging study has shown a stark difference in the architecture of the human brain that helps provide a potential neural basis for the different cognitive strengths in men and women.
According to the study, greater neural connectivity from front to back and within one hemisphere is visible in males, suggesting that their brains are structured to facilitate connectivity between perception and coordinated action.
Washington, Dec. 3 - Scientists are working to determine and to understand the fate of Comet ISON as it moves away from the sun.
The question that is in the mind of scientists is whether the bright spot seen moving away from the sun was simply debris, or whether a small nucleus of the original ball of ice was still there.
Comet ISON, which began its journey from the Oort Cloud some 3 million years ago, made its closest approach to the sun on Nov. 28, 2013.
Washington, Dec. 3 - Researchers have identified and classified more than half a million galaxies, after seven years of close observation of the universe from the Observatory of Calar Alto (CAHA, Almeria) and a technique that is able to break the stars' energy in their colors through astronomical filters.
In addition, this research has also allowed calculating the distances from these galaxies to us with unprecedented accuracy.
Washington, Dec 2 : Scientists were pretty sure until now that they knew how the surface of a neutron star - a super dense star that forms when a large star explodes and its core collapses into itself - can heat itself up .
However, research by a team of scientists led by a Michigan State University physicist has researchers rethinking that.
Scientists had long thought that nuclear reactions within the crust, the thick, solid, outermost layer of the star, contributed to the heating of the star's surface.
Washington, Nov 30 - Astronomers and solar physicists were surprised when the much-hyped comet ISON mysteriously failed to appear in images from extreme-ultraviolet (EUV) solar telescopes on Thursday.
The SWAP solar telescope, on board the Belgium-based ESA mission PROBA2, conducted an extraordinary campaign to image ISON, but failed to detect any sign of the unusual comet.
Previous comets, so-called sungrazers, which follow orbits that carry them to within an astronomical hairsbreadth of the Sun, have appeared bright in EUV images as they raced through the Sun's atmosphere and skimmed its scorching surface.
Washington, Nov 29 - Scientists claim that Comet Ison was completely destroyed after passing the sun.
Billed as "the comet of the century", the ball of dust and ice was travelling at 234 miles a second.
But after passing the sun - with temperatures of 2,760 C - it appears to have broken up.
Astronomers used a fleet of solar telescopes to look for the comet after its slingshot around the sun, but to no avail.
Astrophysicist Karl Battams, with the Naval Research Laboratory in Washington, said he couldn't see anything that emerged from the behind the solar disk, suggesting that the comet was destroyed.
Washington, Nov 27 - Just week after being hit by cyclone Helen, Andhra Pradesh is again preparing to face another 'very sever' cyclone , Lehar, located in the Bay of Bengal.
NASA 's Tropical Rainfall Measuring Mission satellite called TRMM satellite passed over Lehar and measured rainfall and cloud heights to give scientists an understanding of how the storm is behaving.
The TRMM instruments found that rain was falling at a rate greater than 64 mm per 2.5 inches per hour in Lehar's center and in a band of intense rain wrapping around Lehar's northwestern side. Some strong thunderstorms within Lehar were reaching heights above
Washington, Nov 26 - Astronomers have discovered that a reverse shock wave racing inward at Mach 1,000 (1,000 times the speed of sound) is heating the remnant of Tycho's supernova and causing it to emit X-ray light.
"We wouldn't be able to study ancient supernova remnants without a reverse shock to light them up," Hiroya Yamaguchi, who conducted this research at the Harvard-Smithsonian Center for Astrophysics (CfA), said.
Tycho's supernova was witnessed by astronomer Tycho Brahe in 1572.
