Global warming could cause fall in oxygen on Earth, mass mortality: Study

According to researchers, falling oxygen levels caused by global warming could be a greater threat to the survival of life on Earth than flooding.

Indian-origin engineer discovers new green power source

Researchers led by an Indian-origin scientist have developed a novel technology that harnesses electrical energy from blue-green algae that could be used to power cell phones and computers in future.

Oxygen in ocean spread much earlier than previously thought

Iron-bearing rocks that formed at the ocean floor 3.2 billion years ago carry unmistakable evidence of oxygen, much earlier than previous discoveries reported, a new research has found.

Now, derive electricity from photosynthesis

 Researchers have developed micro-photosynthetic cell technology that can harness electrical power from photosynthesis and respiration of blue-green algae.

Plants use less water than previously assumed

Plants use less water than previously assumed

Plants use less water than earlier studies had indicated and freshwater passes more rapidly through soil than previously thought, new research using NASA satellite shows.

'Artificial leaf' powered by solar energy to run future communities

Researchers at Monash University in Melbourne have formulated a solar-powered device that replicates the photosynthesis process that plants and bacteria follow.

Fossil fuel burning threatens radiocarbon dating: Study

Fossil fuel burning threatens radiocarbon dating: Study

Emissions from the burning of fossil fuels are threatening the effectiveness of the radiocarbon dating technique that has been used for decades to accurately calculate the age of a wide range of artefacts, says a new study.

'Vampire' plants good for food chain: Study

 Parasitic "vampire" plants that attach onto and derive nutrients from another living plant may benefit the abundance and diversity of surrounding vegetation and animal life, reveals a new study.

US researchers advance artificial photosynthesis

US researchers advance artificial photosynthesis

US researchers have created a hybrid system of semiconducting nanowires and bacteria to mimic the natural photosynthetic process, an advancement they believe could be a potentially game-changing breakthrough.

First X-ray portraits of living bacteria captured

First X-ray portraits of living bacteria captured

In a first step toward possible X-ray exploration of processes that are important to biology, human health and our environment, researchers have captured the first X-ray portraits of living bacteria.

Scientists closer to making fuel from water and sun

Researchers, including one of Indian-origin, have moved one step closer to turning water and sunlight into sustainable fuel by successfully replicating a crucial step in photosynthesis.

Future air quality may put plants at risk

Future air quality may put plants at risk

By 2050, cumulative exposure to ozone during the summer will be high enough to damage vegetation, estimates an international research team. (13:30)

`Semi-artificial leaf` shows faster photosynthesis than natural counterpart

Scientists have developed a novel method that allowed them to successfully hack into Gmail with up to 92 per cent accuracy.

Spinach may help convert sunlight into clean alternative fuel

Popeye`s favourite snack spinach, which gave the cartoon character super strength, also has the ability to convert sunlight into a clean, efficient alternative fuel.

First ever pic of `photosynthesis in action` revealed

A new study has shown the first snapshots of photosynthesis in action as it splits water into protons, electrons and oxygen, the process that maintains Earth`s oxygen atmosphere.

Satellite technology to measure plant energy activity

In what could provide an improved tool to evaluate the productivity of the breadbaskets of the world - such as the Indo-Gangetic plain, scientists have for the first time made use of satellite technology to measure photosynthetic activity as it occurs around the planet.

Earth breathed first 3 billion years ago!

It was generally believed that cyanobacteria, the blue-green algae, that evolved photosynthesis appeared 2.5 billion years ago when the `Great Oxidation Event` (a spike in oxygen levels) happened.

Satellite to track plant health using fluorescence

It`s not just us `humans`, but plants also glow when they are well. Radiant skin is considered a sign of good health in humans and now plants too.

Maths used to study photosynthesis in new super-crops

Scientists have identified the path that led to the development of new super-crops, which use an advanced form of photosynthesis.
