Smoking causes DNA mutations that make lung cancer more likely: study

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.

Researchers find method to add colors to electron microscopic imagery

Researchers find method to add colors to electron microscopic imagery

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.

Strong vaporizing impact caused Moon’s mysterious tilt: Study

Big vaporizing impact caused Moon’s mysterious tilt: study

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.

Latinos, African Americans have higher rates of diabetes than whites and Asians

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.

Moon helped turn Earth’s right-side up: study

Moon helped turn Earth’s right-side up: study

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.

Natural compound successfully reduces signs of aging in healthy mice

Natural compound successfully reduces signs of aging in healthy mice

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.

Researchers examine first-ever dinosaur brain tissue

Researchers examine first-ever dinosaur brain tissue

The first time discovery of a fossilized brain tissue from a dinosaur is expected to shed more light on the extinct species that lived during the early Cretaceous period, paleontologists believe.

The brain tissue in question, which looked like an unassuming brown pebble, was unearthed by a fossil hunter named Jamie Hiscocks in Sussex, England, more than ten years ago.

Astronomers discover newborn triple-star system

Astronomers discover newborn triple-star system

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.

Claim of evidence of alien life raises scientists’ eyebrows

Claim of evidence of alien life raises scientists’ eyebrows

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.

Japanese Research Team Creates Humanoid Robot that Sweats

Japanese Research Team Creates Humanoid Robot that Sweats

A humanoid robot developed by researchers at the University of Tokyo can sweat and uses this as a cooling mechanism. The motors of some robots generate heat and unless they have a way to cool themselves humanoid robots would not be able to work for longer hours. The robot named Kengoro can perform pushups for 11 minutes, as showcased by the tests conducted by the University of Tokyo team.
