Membranes that twist and turn through the gut in humans’ digestive system has been reclassified and upgraded by scientist to an organ, according to a newly published review.
The structure, which connects the small and large intestines to the abdominal wall and keeps them in place, has been known to scientists for a long time. But, until recently, it was believed to be numerous distinct membranes.
In the review, researchers looked at old and new studies on the structure called “mesentery,” and concluded that the structure is actually a continuous organ.

Eggs of duck-billed dinosaurs took as long as six months to hatch, while the eggs of larger dinosaurs might have taken even longer time to hatch, a new study suggested.
A team of researchers led by Gregory M. Erickson of Florida State University used a new technique on some rare fossils of unhatched dinosaur embryos, and determined that those embryos consumed twice as long to hatch as bird eggs of similar size.

All would-be revelers should be careful with their countdowns this New Year’s Eve as scientists have decided to add a “leap second” to the universal clock at the end of December, delaying the arrival of 2017 by a second.
The leap second will be added in order to bring the world’s atomic clocks in sync with Earth’s own distinctive rhythm, which is determined by the planet’s rotation. The International Earth Rotation & Reference Systems Service (IERS) confirmed in a statement that it would be necessary to introduce an additional second at the end of this year.

The New Year will begin with an eye-catching conjunction of the waxing crescent Moon and the glittering planet Venus on Jan. 1, astronomers have predicted.
According to a statement released by NASA astronomers, the exquisite pairing of Moon and Venus will be seen just after sunset in the southwestern sky.
On January 2nd, Moon and Venus will be back for an encore, but this time our natural satellite will have shifted between Mars and Venus. One will be able to watch the planets of war and love sticking close together all through the month of January.

A new research published in the journal Nature Communications has warned that a long-quiet yet potentially highly-hazardous supervolcano in Italy is nearing the critical degassing pressure (CDP) state.
A team of scientists led by Giovanni Chiodini of Rome-based Italian National Institute of Geophysics, who are monitoring the Campi Flegrei volcano, has noticed accelerating deformation and heating in the volcano, suggesting that magma under surface is approaching a threshold beyond that could trigger release of fluids and gases.

A team of geologists from the University of Rochester claimed to have found a new prehistoric bird species in the Canadian Arctic, marking the discovery of the oldest avian records in the northernmost latitude.
Prof. John Tarduno, the chairperson of the Department of Earth & Environmental Sciences at the University of Rochester, and his team named the new species Tingmiatornis arctica. In the Inuktitut language, which is spoken in the central & eastern parts of Canadian Arctic, the word “Tingmiat” means “those that fly.”

More than three trillion migrating insects fly over the region of south-central England each year, unseen and unnoticed by humans, according to a new study by University of Exeter researchers.
Dr. Jason Chapman, an entomologist at University of Exeter and colleagues estimated that as many as 3.5 trillion bugs and butterflies migrate across the region annually. Their total mass is equivalent to nearly 20,000 flying reindeer.

A team of researchers from the Netherlands have developed a first-of-its-kind synthetic leaf that can act as a mini-factory for drugs that would allow production of life-saving medicines anywhere there is sunlight.
The researcher led by Timothy Noel, of Eindhoven University of Technology in the Netherlands, managed to tap into plants’ photosynthesis-based food-producing abilities.
They made use of a leaf-inspired micro-factory mimicking nature’s efficiency at harvesting solar radiation. To do that, they used new material called luminescent solar concentrator (LSC).

Marking a technological breakthrough, an international team of scientists claimed to have developed a new way to explore antimatter -- using a laser.
A team of researchers led by Alan Kostelecky, a theoretical physicist at Indiana University, successfully zapped antimatter atoms with a laser, and then precisely measured the light emitted by these bizarre anti-atoms.
