Stem cells receive various molecular cues, but they differentiate between these cues i.e. they ignore the irrelevant cues and respond only to the crucial signs by rapidly developing to form major organ systems of the body. To understand how stem cells are able to do this, researchers at University of California, San Francisco (UCSF) studied engineered cultured mouse embryonic stem cells.

A team of researchers from The Scripps Research Institute (TSRI) and the Janssen Pharmaceutical Companies of Johnson & Johnson (Janssen) has developed a vaccine that provides immunity against a wide range of influenza subtypes. Read on to learn more about this.

Humans are intelligent creatures and use medicines to treat themselves. However, do ants know how to treat their ailments? Researchers from the University of Helsinki, Finland, discovered that ants are capable of recognizing that they are sick and can self-medicate. Read more about their research here.

Stick insects, one of the most peculiar insects found on earth, have intrigued scientists by exhibiting how the process of natural selection can prevent the formation of new species. A team of researchers from the University of Sheffield in England and the University of Colorado Boulder studied a plant-eating stick insect species from California called Timema cristinae.

Researchers from Arizona State University, University of Helsinki, University of Jyväskylä, and Norwegian University of Life Sciences have discovered that queen bees have a unique way of immunizing their babies against external pathogens found in the environment. Read on to learn more about this.

rVSV-ZEBOV, an experimental Ebola vaccine, has successfully provided complete protection against Ebola infection in people who are at high risk of contracting the virus. The Public Health Agency of Canada developed this vaccine using an attenuated livestock virus engineered to produce an Ebola protein. Read on to learn more about this.

The discovery of a four-legged fossil snake has provided a new direction to the long-standing argument of researchers over the evolution of snakes. The fossil is named Tetrapodophis amplectus, which loosely translates as ‘four-legged hugging snake,’ and is being considered as a missing link between snakes and lizards.

Using NASA's Kepler Space Telescope, astronomers from the U.S. have discovered a planet that they believe is significantly similar to Earth. This planet that has been dubbed as Kepler-452b is in the habitable zone of the star it circles. Read on to learn more about this.

The researchers at the Large Hadron Collider (LHC) at CERN near Geneva have discovered a new class of particles called ‘pentaquarks.’ The tiny ingredients of sub-atomic particles such as protons and neutrons are called quarks. Protons and neutrons are made of three quarks. The existence of a five-quark version, or "pentaquark," was theorized by American physicist Murray Gell-Mann in 1964, but it was never found.

An influential group of US astronomers have proposed the building of the High-Definition Space Telescope (HDST), the biggest and most advanced space telescope, according to the Association of Universities for Research in Astronomy (AURA) report published on July 6. The HDST would complement the James Webb Space Telescope (JWST), which will be launched in 2018 and will observe the universe at infrared wavelengths. Read on to learn more about this.
