Scientists found that blue tits, collared flycatchers and pied flycatchers can notice flickers as fast as 140 Hz. How would a speeding Usain Bolt look for them?
The overarching sense is that it is religious practice and use, rather than ecology, science or animal cognition, that is the shining light for subliminal but broad changes in our environmental policies.
One reason to expect the three genes used in transgenic mustard to be safe is that they aren’t new at all. They have been in the human food-chain for around two decades now.
The idea of a shared space is the best way to respect our histories, our traditions of peaceful engagement, the cultural geographies we inhabit — all with blurred and indistinct boundaries and interrelated contexts of meaning.
Ulsoor Lake is one of the last strongholds in a water-starved city whose hundreds of old reservoirs have largely been drained to be built upon or reduced to dumping grounds in the last 40 years.
While the WTO decision on India’s solar programme may have been a hit to the ‘Make in India’ campaign, our arguments surrounding the domestic content requirements aspect simply didn’t make the cut.
In a single generation, snakes have become more valuable to the Irula alive than dead.
A parasite has been found to protect the economically important brine shrimp from arsenic poisoning.
Prior to this, 36 species belonging to 14 different genera were known from the Western Ghats in the family of freshwater crabs. The latest discoveries bring the total species count to 41.
The real challenge that we face today is whether we can scale up efforts to reconnect the habitat dots across India.
After analysing samples directly obtained from around the leak site, scientists found that the amount of methane released was equal to those emitted by mid-sized European countries in a year.
At a time when public debate about nationalism and the idea of India is being intensely conducted across university campuses and in millions of drawing rooms, we must remind ourselves that our lives, culture and understanding of land are ecologically grounded. An ecological perspective interrogates dominant views of […]
India may be better served by a plan that looks at developing solar and other renewable energy generation in step with cost effective storage and flexible generation that is available to all states.
The ‘human’ in ‘human-wildlife conflicts’ suggests that many drivers of conflicts are the result of poor management, misguided clearance decisions and apathy.
If the behaviour of our closest relatives can change so dramatically, what are the implications of the parasite’s hold over humans?
A $48-billion (Rs 3.26 lakh crore) penalty claimed by the US government from Volkswagen for cheating on diesel-car emissions is about 200 times as large as the $225 million (Rs 1,500 crore) insurance pool set up by Indian insurance companies to compensate US nuclear companies for mishaps in […]
Until researchers come up with an experiment that rules out some variables, the jury on whether animals can have abstract thoughts is still out, and definitely not settled against their favour.
In spite of the 8 million new toilets constructed, patterns of toilet usage haven’t changed much. Analysing cultural variations in toilet use provides surprising insights into why this might be so, and what can be done to change it.
For a long time, scientists thought consolation was a uniquely human trait. This barrier separating humans from animals is being battered down by species after species.
Given that mosquito-borne diseases are amongst the biggest killers on Earth today, going for a complete eradication is never out of health officials’ minds.
Seeing the strength of the campaign, politicians from all major parties have now extended support for the cause.
Ants may not have dodged death, but remaining spry as spring in the evening of one’s life is enviable.
The answer is both dissatisfying and thrilling all at once.
Some of the causes being explored by the scientists are the shape of the coastal topography that traps them and the tight social relationships with others in the pod that may predispose them to strand.
Could Spider Man climb up skyscrapers like he does in the comics? Scientists say that normal-sized sticky hands and feet alone won’t help him.
A tool used by biologists to study evolution is called phylogenetics, in which the scientist attempts to make connections among extant species based on a set of measurable properties.
I met Rajni Kothari – who passed away one year ago on January 19, 2015 – briefly in the summer of 1986 when I had travelled to India for a summer internship. Although we did not have an extended interaction, the fact that he had agreed to my request […]
A discovery is made only when the appropriate tools required for that discovery are invented – and almost never completely by chance.
The societal, economic and ecological disasters of marine bioinvasions are not natural ones, and they are becoming more common.
If you thought trust was a unique trait of humanhood, you’d be mistaken. Our close relatives – the chimpanzees – trust too. This recent finding pushes the origin of trust way back to a common ancestor.
Marine animals’ ability to navigate across open seas has long been a mystery. Scientists now have an inkling of how sharks find their way.
When going up trees, snakes use a type of crawling called the concertina that isn’t only fast but also likely saves energy.
The present attempt to reduce the number of cars on the road is well-intentioned but misguided in the long-run unless there is the political will to adopt a wider set of restrictions.
Imphal: Six unnatural deaths, 70 injured on a single day is by all means a tragedy. This despite the desensitisation to violent deaths that insurgency torn places like Manipur has undergone. But the fact is the casualty figure from Monday’s tremblor could have been much worse, if at […]
Before you draw your next breath, be aware that it could seriously damage you. Scientists have estimated that air pollution by prevailing PM2.5 levels will have led to 6.6 million premature deaths by 2050.
Puff adders can give even trained dogs the slip.
While such initiatives are likely to work for shorter periods when pollution levels are too high, for people to change their travel habits and leave their cars for public transport, walking and cycling, there needs to be considerable public investment in these areas — and a change of mindset.
With great confidence and supposed vision, we decided that infectious diseases were a done deal, and research funding for these areas were curtailed. Unfortunately, we did not factor in evolution.
During a famine, vole populations can crash. Those with better navigation and memory skills dote on their partners, defend their mates from philandering males, and make successful parents.
Armed with low-cost sensors, some people are trying to keep a check on the quality of air around them. Personal benefits aside, can this technology help combat pollution on a larger level?
