Killing animals a regular practice in zoos 

 Zoos have always been a grey area when it comes to animal lovers and conservationist. While some argue that it offers a safe haven for endangered animals who have lost their habitat in the wild, (thanks to our voracious need to spread ourselves on the planet), some argue that confining these creatures is as good as torture. But the argument against zoos has become stronger because of the practice of Zoothanasia – a common practice of zoo to put down perfectly healthy animals because they don’t fit their economical budget.

Animals showing morals values 

if you thought that morals and values were traits that were exclusively human, you are gravely mistaken. Time and again, researchers, conservationist world over come face to face with instances where animals have shown compassion, morality a sense of right and wrong (or at least come close to it). It just goes to show how much we really know about animals. …

Catching up with Science!

There is a lot that is going around in the world and there is only so much time on our hands. Because we do so much of reading (you know, for obvious reasons) we are happy to bring to you the most interesting stories every month, published on other blog, news sitesand university website feeds. 
Worms that have three sexes
Now here’s a fun story that you can throw around in a group discussion to grab a few head turns. The worm in question is the Auanema rhodensis, a curious little (quite little) being that is found in the Connecticut and Virginia. Now three sexes in invertebrates are not uncommon, from earthworms to snails and even many fish are hermaphrodites. But what makes these A rhodensis so special is that they are self-fertilising   hermaphrodites, which is not heard of, at least till now. Diane Shakes professor of Biology at the College of William and Mary is one of the authors of the paper that speaks about these curious little specimens. You can read the full article here.

Future deafness treatments will be genetic in nature

As per estimates released in 2015, Deafness or hearing loss affects 1.1 billion people globally. There are many causes of deafness ranging from trauma to the ear to severe infections, developmental issues as well as exposure to noise. However, 80% of deafness cases are non-syndromic i.e. do not show any other symptoms such as ear malformations and are also genetic in nature. 
Cochlear implants have met a lot of success in recent years but come with its own set of benefits and risks and are definitely not a permanent cure. Like with any other genetic condition, deafness, too, has been known to be non-curable. But recently published research puts hope on the horizon for patients with deafness that gene editing technology could one day become mainstream and allow treatment for genetic deafness. 
Gene Editing technologies have taken the scientific world by storm in the recent years. Among these, CRISPR - Cas 9 system has gained quite a reputation for itself. What was published as general…

RotM: Interview with Dr. Michael Loik

For this month's Researcher of the Month, we spoke to Professor Michael Loik, at the Environmental Studies Department at University of California at Santa Cruz (UCSC). The Loik Laboratory has been studying the impact of short term weather patterns, changes in atmospheric composition and changes in plant physiology as a result of climate change in arid and semi-arid ecosystems.
Using results from their studies, the lab prepares communities for the ongoing climate change and devises information for adapting to fire risks and droughts. With a focus on reducing the emission of green house gases, the Loik laboratory also works on finding innovative solutions for farmers, which we will discuss today. 
Before, we get started, here is a video summary of his recent publication in the journal Earth's Future.

A man of few words, Prof. Loik was quick to revert to our queries regarding this wonderful accomplishment of his team. 
CTS: Where did the idea behind WSPV (Wavelength Specific Photo Vo…

Genetic Mutation helps Amish live longer, healthier!

Genetic mutations are usually associated with bad news. A mutation in BRCA genes could put you at risk of breast or ovarian cancer or give you a blood disorder like thalassemia or haemophilia. From cystic fibrosis to phenylketonuria, colour blindness to polycystic kidney, there is a long list (some rare, some not so rare) of diseases caused by mutations. 

Although, Marvel Comics has done a lot on its part to promote the good that can come out of harboring a rare mutation, the benefits are yet to reach the common man. A commonly cited example for good mutation is the resistance to malaria that is conferred by the Sickle Cell mutation, but it does come with the risk of getting two copies of the mutation and being affected by sickled red blood cells. There are a few other mutations that seem to help people lower their risk for heart diseases, get stronger bones or improve their under water vision.
But, a recently published paper in Science Advances puts light on a mutation in SERPINE1 gene …

RotM: Interview with Marie Hornig

For the current instalment of Researcher of the Month, we spoke to Marie Hornig, a third year PhD student at the Cytology and Evolutionary Biology Department at the University of Greifswald, Germany. Her recently published paper, co-authored by Joachim Haug and Carolin Haug, researchers at the Ludwig Maximilian University of Munich, provides further details about the predator behaviour in mantodeans (animal order that consists of insects such as praying mantis and some 2400 other species). The subject of her study was a praying mantis fossil that is 110 million years old. 

CTS: The smallest of discoveries regarding dinosaurs get highlighted in the media. Here, a fossil preserved over 110 million years exists among us and there is hardly any mention in the media regarding this?
MH: I am fully aware that the focus of media does not represent the recent scientific findings, since non-vertebrate species have never gotten the attention that vertebrates do.
CTS:How do you feel about this? 

Tomato plant turns small worms into cannibals!

For many many years I strongly believed that plants were helpless creatures, slowly trying to make some space for themselves between the concrete jungles and cultivated land that humans occupy. Dependent on the Earth, the Sun and the rains for their survival, plants were still toiling to give away to the world the sweet fruits of their labour and the precious oxygen that we simply cannot do without. 

But as I continue to read about plants while researching for this blog, I realized many things about plants. First and foremost, just like our own guts, they have their own microbiomes and work closely with other microbes for their own survival. If that was not sufficient, I also learnt that plants can actually sense when a herbivore attacks them and can be quite patient with the herbivore, before they decide to release certain chemicals that make the leaves taste so awful that the herbivore probably does not want to eat it anymore. Although it becomes a tasty delight for us is a different…
