Washington D.C. [USA], Feb. 18 : To boost breeding of endangered poultry breeds, Briton researchers have come up with gene-editing techniques for the rare breeds to use them as surrogates that cannot produce their own chicks.
The advance -- using gene-editing techniques -- could help to boost breeding of endangered birds, as well as improving production of commercial hens, researchers say.
The appeared in the journal Development.
Researchers explained that donor primordial germ cells from other breeds could be implanted into the gene-edited chickens as they are developing inside an egg. The surrogate hens would then grow up to produce eggs containing all of the genetic information from the donor breeds.
New York [USA], Feb. 17 : NASA has called on the world to help it in the search for the new ninth planet, as anyone from a kindergartener to a 95-year-old, can participate in their new project to find the not-yet-discovered celestial body.
To let anyone participate in this search project of ninth planet, the Zooniverse space projects site has launched a NASA-funded venture, Backyard Worlds: Planet 9, reports CNN.
"There are really low barriers to entry," Dr. Laura Trouille of Zooniverse.
NASA has compiled a "flipbook" of short animations that shows sky scans taken over several years and so far, 4,201 people have joined the mission.
The participants can search for disruptions in the images -- basically, clusters of tiny coloured dots -- and mark their findings.
Washington D.C. [USA], Feb. 8 : According to an international team of astronomers led by researchers from University Of Cambridge, the Magellanic Clouds, the two largest satellite galaxies of the Milky Way, appear to be connected by a bridge stretching across 43,000 light years.
The discovery is based on the Galactic Stellar census being conducted by the European Space Observatory, Gaia and reported in the journal Monthly Notices of the Royal Astronomical Society (MNRAS).
For the past 15 years, scientists have been eagerly anticipating the data from Gaia. The first portion of information from the satellite was released three months ago and is freely accessible to everyone.
Washington D.C. [United States], Jan. 18 : The United States has made an additional USD500 million grant to support the Green Climate Fund (GCF).
Consistent with last year's GCF grant, this funding is provided from the fiscal year 2016 Economic Support Fund (ESF) appropriation.
"This grant follows last year's initial grant of 500 million as part of the $3 billion pledge to the GCF made by President Obama in 2014," said U.S. State Department spokesperson John Kirby.
He said the Green Climate Fund is a critical tool that helps catalyse billions of dollars in public and private investment in countries dealing not only with the challenges of climate change but the immense economic opportunities that are embedded in the transition to a lower-carbon economy.
Washington [USA], Jan. 18 : To encourage the conservation in the fragile areas, scientists have named a new moth as 'Neopalpa donaldtrumpi' in the honour of U.S President-elect Donald Trump.
Biologist Dr. Vazrick Nazari from University of California named the moth officially as ' Neopalpa donaldtrumpi' because it stands out with yellowish-white scales present on the head in adults and in these scales he found an amusing reference to Trump's hairstyle and turned it into an additional justification for its name.
The study, published in the open access journal ZooKeys, hopes that the fame around the new moth will successfully point to the critical need for further conservation efforts in the fragile areas such as the habitat of the new species.
Washington D.C. [USA], Nov.30 : Google, on Wednesday, wished noted scientist Jagdish Chandra Bose on his 158th birth anniversary with a doodle featuring him.
The doodle featured Bose's caricature with crescograph, an instrument that he invented to measure growth in plants.
Best known for his pioneering work in biophysics, Bose made several contributions in various fields, including physics, biology and archaeology.
Washington D.C. [USA], Nov. 29 : Is it possible for humans to regrow an amputated arm or leg, or completely restore nervous system function after a spinal cord injury?
It might be possible one day, as a new study of one of our closest invertebrate relatives, the acorn worm, reveals that acorn worms can regrow every major body part, raising hopes for regeneration in humans.
Acorn worms burrow in the sand around coral reefs, but their ancestral relationship to chordates means they have a genetic makeup and body plan surprisingly similar to ours.
Washington D.C. [USA], Nov. 29 : A new research has found that toddlers learn new words using the same method as robots.
The study suggests that early learning is based not on conscious thought but on an automatic ability to associate objects which enables babies to quickly make sense of their environment.
Dr Katie Twomey from Lancaster University, with Dr Jessica Horst from Sussex University, Dr Anthony Morse and Professor Angelo Cangelosi from Plymouth wanted to find out how young children learn new words for the first time.
The researchers programmed a humanoid robot called iCub designed to have similar proportions to a three year old child, using simple software which enabled the robot to hear words through a microphone and see with a camera.
Washington D.C. [USA], Nov.24 : The research, which says area of sea ice around Antarctica has barely changed in size in a century, was contributed by the heroes of Antarctic exploration.
Ice observations recorded in the ships' logbooks of explorers such as British Captain Robert Scott and Ernest Shackleton and the German Erich von Drygalski have been used to compare where the Antarctic ice edge was during the Heroic Age of Antarctic Exploration (1897-1917) and where satellites show it is today.
The study suggests Antarctic sea ice is much less sensitive to the effects of climate change as compared to the Arctic, which in stark contrast has experienced a dramatic decline during the 20th century.
Washington D.C. [USA], Nov.24 : A new study, collecting genetic data by an international group of scientists, says that a common species of Asian tree frog may actually be two separate species.
If the two groups of frogs are confirmed to be different species, assigning their scientific names may require searching historical records of foreign explorers in Japan during the 1800s.
Before the frogs are officially recognised as two separate species, researchers will test if individual frogs from the two groups have unique physical or behavioral features and if they can produce healthy offspring.
Washington D.C. [USA], Nov. 23 : A recent study published in the journal Royal Society Open Science, found that amphibians which use poisonous defenses are more likely to get extinct than other species.
Research published by a Swansea University scientist has suggested amphibians which have a toxic defence against predators such as the iconic poison dart frogs have a much higher risk of extinction than species which use other types of defence mechanisms.
The key finding of Dr Kevin Arbuckle's latest study is that poisonous species are 60 percent more likely to be threatened than species without chemical defences.
Amphibians are usually considered the most threatened group of vertebrate animals and are experiencing population declines globally, raising conservation challenges.
Washington D.C. [USA], Nov. 21 : A new research draws attention to recent data rescue efforts undertaken in Australia to study the climate and climate change, in the southern latitudes.
The article has been published in published in Advances in Atmospheric Science journal.
Long-term weather data is the backbone of almost all research into climate change and variability.
The recovery of historical instrumental data is a well-established practise in the Northern Hemisphere, where observations are available for the past several centuries in many regions.
In the Southern Hemisphere, the currently available set of climate observations generally only begin in the early to mid-20th century. This makes it harder to study the climate change.
Kourou(French Guiana) [US], Oct. 6 : India's latest communication satellite GSAT-18 was on Thursday morning successfully launched by a heavy duty rocket of Arianespace from the spaceport of Kourou in French Guiana.
The European launcher Ariane-5 VA-231 blasted off at around 2 a.m. Indian Time and injected GSAT-18 into a Geosynchronous Transfer Orbit, shortly after orbiting co-passenger Sky Muster II satellite for Australian operator, National Broadband Network.
The launch, which was originally scheduled for yesterday, was deferred by 24 hours due to unfavourable weather conditions at Kourou, which is a French territory located in north-eastern coast of South America.
Washington D.C. [USA], Oct. 3 : Taking us a step ahead to understand sex differentiation, a recent study has revealed that key sex-determining genes continue to operate in a mammalian species that lacks the Y chromosome.
In most placental mammals, the Y chromosome induces male differentiation during development, whereas embryos without it become female.
The sex-determining gene SRY is present on the Y chromosome and induces other regulatory genes that suppress female differentiation. The Amami spiny rat (Tokudaia osimensis) is exceptional as it lacks a Y chromosome and thus the SRY gene, raising the question of why male differentiation can still occur.
Bhubaneshwar (Odisha) [India], Sept. 21 : The test-fire of new long range surface-to-air ballistic missile Barak-8 will continue on the second day today from Integrated Test Range launch pad at Chandipur off Odisha coast.
The Indo-Israel joint venture missile is having multi-functional surveillance and threat alert radar was successfully test fired twice from the Range yesterday.
Earlier, this year Barak-8 was successfully test-fired twice on 30th June and once on July 1.
The 4.5-meter missile weighs around three tonnes and can carry a payload of 70 kilograms.
The system also includes a Multi-Functional Surveillance and Threat Alert Radar for detection, tracking and guidance of the missile. (ANI)
Climate change will impact almost every region of the planet in the coming times and the impact can be seen in terms of unpredictable and inclement weather, which would impact crop yields. It is important for governments to be ready to combat these changes as there could be food scarcity and people in the coastal regions would face frequent flooding. Climate scientists found that nations around the world that are at high risk of catastrophic impacts of climate change are among the poorest.
Busting the notion that modern-day parents are the first ones to keep tabs on their children to safeguard them from potential dangers, a new study has claimed that the practice began as long as 430 million years ago.
Published Monday in the Proceedings of the National Academy of Sciences, the study described a tiny, resourceful arthropod creature, Aquilonifer spinosus, which devised a unique way for baby tracking. Aquilonifer spinosus tethered egg pouches to its back with threads and followed its juveniles as they grew, in a similar manner as if they were tiny kites. The aim was to keep the young ones tethered to the adult’s body with strings so as to keep them safe.
Astronauts have started training on Orion spacecraft for preparation of an eventual trip of transporting spacefarers to the Red Planet. The test crew wore spacesuits to properly test the vehicle and to check their own ability of interacting with control systems while attired in full gear.
The Orion spacecraft has been designed to be the next space delivery system of the US space agency that can lift human payloads to orbit, and outside our planet. The vehicle is the keystone of NASA’s quest of transporting people to Mars.
A recently found exoplanet using Kilodegree Extremely Little Telescope (KELT) has three Suns in its sky. Though scientists know a number of planets with two Suns, the case of a planet with three bright stars in its sky is uncommon.
The newly discovered far away world, called KELT-4Ab, orbits a single star, and that star in turn is orbited by a close pair of stars.
A new study has revealed that the twin stars are sufficiently close to the planet to look as bright as the sky’s full moon is.
Besides coming up as an example of a solar system quite distinct from our planet, the odd arrangement could shed some light over the evolution of gas giants present close to their parent star, called ‘hot Jupiters’.
With the use of satellite imagery, archaeologists claim to have identified a site at Point Rosee in Newfoundland, Canada, that could probably be the first new Viking site discovered in North America in the past over five decades.
Archaeologists believe the newly discovered site has the potential to rewrite history, particularly the portion before the time of Christopher Columbus when Europeans explored North America.
Prior to this, it was in the 1960s that the only other Viking site in North America was found at L’Anse Aux Meadows on the northern tip of Newfoundland, about 300 miles from Point Rosee.
