The National Aeronautics & Space Administration (NASA) has confirmed that its Mars rover Curiosity has found a dark grey, golf-ball-size object on the Red Planet that seems to be a meteorite.
Curiosity stumbled upon the so-called ‘Egg Rock’ meteorite last week, and the U.S. space agency announced its discovery yesterday, saying the small rock looks nothing like the archetypal reddish rocks that are typically found on Mars. The strange rock was found on Mount Sharp on the Red Planet.

Every year of cigarette smoking causes DNA mutations in lung cells that make the deadly disease of cancer more likely, according to a study published in the most recent edition of the journal Science.
Researchers found that those who smoke a pack of cigarettes daily for a year make the DNA in every cell in their lungs to acquire nearly 150 new mutations. The cells in the larynx acquire nearly 97 new mutations, while the pharynx and oral cavity accumulate 39 and 23 new mutations, respectively.

Electron microscopes enables users to look at as minute things as viruses and bacteria, but existing microscopes are not able to provide colorful images because when things get too small, they go dark as well.
However, that problem has apparently solved as a team of researchers at the Center for Research in Biological Systems at UC San Diego have developed a new method that adds color to electron microscopic imagery.

A new study has apparently solved the mystery as to why of the Moon’s orbit is slightly inclined as compared with Earth’s orbit around the Sun, by roughly 5 degrees.
Major planets in out solar system, including Earth, follow orbits around the Sun that lie within a thin, flat zone defined by the host star’s equator. Scientists believe that it is because these planets arose from a protoplanetary disk of gas & dust that once encircled the star’s midriff.

Latino and African American adults have notably higher rates of diabetes than White Americans and Asians, stats released by the L.A. County Department of Public Health showed.
According to fresh stats, 13.7 per cent of Latino adults and 10.7 per cent of African Americans have diabetes, while rate of the disease among both whites and Asians is 8.2 per cent. The trend also confirmed that that the disease continues to grow.

Most scientists believe that the Moon came into existence after a massive collision around 4.5 billion years ago, when a Mars-sized object dubbed Theia grazed Earth. But this widely-accepted impact theory doesn’t explain how Earth’s axis turned to a more upright position and why there is a difference between orbital tilts of our planet and its only natural satellite.

A new research conducted by a team of scientists at Washington University School of Medicine in St. Louis has suggested a new way to reduce signs of aging.
The scientists supplemented healthy mice with a natural compound, dubbed NMN, and found that it reduced signs of aging such as gradual weight gain, declines in physical activity and loss of insulin sensitivity.

Providing astronomers first of its kind glimpse into how multiple-star systems come into existence, Chile-based ALMA telescope has captured a litter of newborn stars emerging from the same disk of gas and dust.
The image captured by the powerful telescope shows a triple-star system, with two young stars forming in a spiral around an older star. It confirms the major theory that states how multiple stars wind up close to each other.

Two astronomers, viz. Ermanno Borra and Eric Trottier of the Quebec-based Université Laval, claimed to have found evidence of intelligent alien life but their claim has raised some scientists’ eyebrows.
Borra and Trottier examined more than 2 million stars catalogued from the Sloan Digital Sky Survey, and determined that 234 of them exhibit spectral modulation or rapid bursts of light. They said the signals from the stars are consistent with signals from an alien civilization sending tremendously rapid optical pulses predicted previously in an earlier research paper by Borra.
