New imaging technique developed to see epigenetic activity

New imaging technique developed to see epigenetic activity

There is a particular enzyme known as histone deacetylases (HDACs), which has received a lot of attention with regard to neurological disorders, addiction and depression. Researchers have developed a new imaging technique to see the gene activity in the brain for the first time.

Scientists said that they are aware that HDACs are involved in changing gene expression, but they were not having proper information. They wanted to know the difference in the activity of the gene in healthy brains and afflicted ones.

Environmental causes could be behind dogs’ declining sperm quality: Study

Environmental causes could be behind dogs’ declining sperm quality: Study

A decline of 30% has been witnessed in fertility of five common dog breeds in Britain, according to a new study. The research paper published in Scientific Reports has unveiled about declining sperm quality and other effects. The decline might have been taking place due to environmental conditions.

The researchers have observed the male dogs’ fertility rate for over 26 years and came to know the progressive forward movement of sperm has declined by 30% in five breeds- Labrador retrievers, golden retrievers, curly coat retrievers, Border collies and German shepherds.

Oregon Zoo culminates its summer program by releasing last batch of silverspot butterflies into wild

Oregon Zoo culminates its summer program by releasing last batch of silverspot butterflies into wild

The Oregon Zoo is done with the last leg of its program aimed to raise the number of Oregon silverspot butterflies. The zoo has released the last batch of its zoo-raised yellow-and-black butterfly in coastal habitats.

In the last month, the zoo has released around 450 butterfly pupae in four different sites along the Oregon Coast. There was a time when these butterflies were quite common in coastal habitats. Zoo conservation research associate Karen Lewis shared that the silverspot is now listed as threatened under the Endangered Species Act.

Researchers unveil about first known dinosaur to suffer from septic arthritis

Researchers unveil about first known dinosaur to suffer from septic arthritis

Researchers have provided details of the first known dinosaur that suffered from septic arthritis, a crippling form of arthritis. Researchers have discovered the dinosaur’s two forearm bones, radius and ulna.

Though researchers are not completely sure about the species, they probably think that it would be a duck-billed dinosaur also known as hadrosaur, which lived around 70 million years back. This form of arthritis also takes place in humans, birds and crocodiles.

Birds that continue to fly for weeks lack sleep-deprivation syndrome: Study

Birds that continue to fly for weeks lack sleep-deprivation syndrome: Study

A new study can be considered as the first ever to document that certain bird species can fly for weeks at a stretch without touching ground even once. Researchers from the Max Planck Institute for Ornithology have unveiled that frigatebirds, tropical seabirds, have the ability of varying degrees of sleep while flying.

The researchers have based their finding on the brain activity of 15 frigatebirds for over 10 days and 3,000 miles. Majorly, the birds maintained certain amount of alertness by putting just one hemisphere of brain into rest mode.

Affluent areas host larger diversity of insects: Study

Affluent areas host larger diversity of insects: Study

You would be surprised to know that posh areas have a larger diversity of critters, including spiders, ants, beetles, flies and other creepy crawlies. The research will help in shedding the idea that only poor areas have pest problem.

Entomologist Vernard Lewis from the University of California at Berkeley said that the creatures are everywhere. The research paper published in the journal Biology Letters has shown as to how interconnected humans are with their environment.

DNA’s ability to absorb damage is why we evolved DNA-based genomes and not of RNA: Study

DNA’s ability to absorb damage is why we evolved DNA-based genomes and not of RNA: Study

A research paper published in the journal Nature Structural and Molecular Biology has unveiled as to why DNA is the main storehouse of genetic information and not RNA. The DNA double helix can alter itself into different shapes to absorb chemical damage to basic building blocks A, G, C and T of genetic code.

In the case of RNA, it is not flexible and rather than adjusting for damages bases, it falls apart. The FNA double helix is considered to be the back bone when it comes to genome stability and preventing health complications like aging.

For long life, prefer protein from plants than from animals

For long life, prefer protein from plants than from animals

Giving preference to protein from plants than from animals may help you live longer even if you have unhealthy habits like heavy drinking or smoking, unveils a new study. Study researchers have affirmed that plants are better source of protein than animal products.

Study’s lead researcher Dr. Mingyang Song from Harvard University and Massachusetts General Hospital in Boston, in protein, it is also important as from where it comes and how much people eat. Song said that if you are choosing to have animal products then avoid processed red meat and choose fish or chicken.

Scarcity of drinking water and its over-use caused demise of last woolly mammoths: Study

Scarcity of drinking water and its over-use caused demise of last woolly mammoths: Study

A group of woolly mammoths living on the St Paul Island, one of the last known groups of woolly mammoths, died around 5,600 years back owing to lack of drinking water. Warming climate resulted into lakes to become shallower owing to which the animals were unable to satisfy their hunger.

Majority of the world's woolly mammoths died around 10,500 years back. According to scientists, human hunting and environmental changes played a role in their extinction. But there was group living on St Paul Island, located in the Bering Sea, which managed to live another 5,000 years.

Hexacopter drone helps Hawaii researchers to count whale calves without hindering their privacy

Hexacopter drone helps Hawaii researchers to count whale calves without hindering their privacy

Usage of drones in wildlife research is increasing. Lately, it has been found that the technology is being used by NOAA researchers in the Hawaiian Island so they could count the whale calves without disturbing them.

For the first time this summer, ecologists have used drones to come up with proper lists of the whale and dolphin pods near Hawaii. The drones’ inclusion with the NOAA’s recent whale-expedition is another function of what drones can do. Already, drones presence is on rise in police work, real estate, or even firefighting.
