DNA-based circuits could prove immensely useful in field of science and medicine

DNA-based circuits could prove immensely useful in field of science and medicine

A research paper published in ACS Synthetic Biology has unveiled about the creation of a DNA-based circuit that one day may prove useful in the field of science and medicine. DNA, also known as blueprint of life, has genetic code that makes humans different from other species of animals and also from each other.

Study’s lead researcher John Reif, from Duke University and team shared about their development. As per them, they have developed strands of synthetic DNA that when mixed in a test tube results into formation of an analog circuit.

Fish pee helpful in maintaining healthy coral

A Nature Communications-published study unveiled that fish urine is vital for the health of coral reefs. Coral reefs are dependent on fish for key nutrients as they help corals grow. When fish urinate, they release phosphorus in the water.

Usage of neonicotinoid insecticides behind continuous decline in wild bees across England

Usage of neonicotinoid insecticides behind continuous decline in wild bees across England

Researchers have blamed long-term decline in the population of wild bees in England on neonicotinoid insecticides. For more than 18 years, researchers have assessed bees which heavily forage on oilseed rape, which is heavily treated with neonics.

There have been many studies in the past that have unveiled that decline in the honey bees and bumble bees’ population on noenics. In the current study, the researchers have assessed the impact of populations of 62 species of wild bees across England from 1994 to 2011.

Googly-eyed stubby squid makes scientists and internet users go crazy

Googly-eyed stubby squid makes scientists and internet users go crazy

A googly-eyed stubby squid has been spotted by E/V Nautilus while it was exploring the ocean floor in California. The vehicle tried to move as close to the species as possible so as to determine whether it is an octopus or cuttlefish.

When the vehicle went closer, scientists were amazed to see the species as it seemed that a child has dropped his toy. Upon further assessment it was found that the cephalopod was a Stubby squid also known as Rossia Pacifica, closely linked to cuttlefish.

Tobacco hornworm moth genome sequenced by researchers

Tobacco hornworm moth genome sequenced by researchers

Years of collaborative study at various research facilities across the world has resulted into successful genome sequencing of tobacco hornworm (glutton caterpillar). Researchers from Kansas-State University have shared that this tobacco hornworm is known at ‘gluttonous caterpillar’ because it eats a lot before it grows into the Carolina sphinx moth.

Steamy weather makes cockroaches more active: Research

Steamy weather making cockroaches more active

As Americans have been feeling above-average heat this summer, with temperatures soaring into the mid-80s; conditions are ripe for the much-maligned pests to get active.

The steamy weather is prompting the domesticated versions of the brown-colored bugs or cockroaches to spread their wings and fly, taking to the air. According to entomologists and bug experts, the combination of heat and humidity is responsible for the situation.

Researchers develop self-healing fabric

Researchers develop self-healing fabric

In future, we might not need a sewing needle to fix torn clothes as Pennsylvania State University (PSU) researchers have developed a nifty self-healing fabric. To develop the self-healing or self-mending fabric, the researchers applied a very simple process. They dipped torn clothes in certain special liquids, and the special coating of the certain liquids the ordinary clothes into self-healing clothes.

Greenland sharks may live to the age of 400 years: Research

Greenland sharks may live to the age of 400 years: researchers say

The Greenland shark, also known as Somniosus microcephalus, is the longest-living vertebrate on Earth as this huge marine creature can probably live for as many as 400 years, according to a new research published in the journal Science.

A group of marine biologists at Indiana University South Bend estimated that the Greenland shark could have a lifespan ranging from 272 years to nearly 400 years.

UK’s Chester Zoo Becomes the First World's Montserrat Tarantula Nursery

A hundred years have passed since the first time Montserrat tarantula (Cyrtopholis femoralis) was observed in the Caribbean island bearing the same name. A male specimen was collected then and it gave us all the information we have had so far regarding behavior or the breeding pattern of these tarantulas.

Spending life in cold northern waters could be reason behind Greenland sharks’ unusual longevity

Spending life in cold northern waters could be reason behind Greenland sharks’ unusual longevity

A journal Science-published research paper has unveiled that Greenland sharks can live longer than any other known animal with a backbone. Greenland sharks grow very slowly, less than a centimeter per year therefore they are considered to be quite ancient.

Julius Nielsen, at the University of Copenhagen in Denmark, said that they were having an idea that sharks might be quite old. But without a doubt it was a big surprise for them to know that it was the oldest vertebrate animal.
