Alyssa Azar set out early on Saturday for the final climb of about 800 metres to the peak of Mount Everest. She has become the youngest Australian to scale Everest.

Queensland teenager Alyssa Aza is all set to become the youngest Australian to climb Mount Everest. The 19-year-old daredevil mountaineer will make her record-breaking attempt on Saturday.

Cannabis cultivation may soon turn out to be a major industry for drought-stricken farmers in South-west Queensland. The Federal Government’s decision to legalise medical marijuana has been hailed by farmers.

The three-billion-year-old mega-tsunamis in Mars caused waves that averaged 50 metres in height but rose up to the height of 30-storey buildings. They decimated shorelines and paced inwards.

Scientists may finally learn something about our Solar System’s origins after they discovered frozen comets orbiting a sun-like star (HD 181327). The researchers detected extremely low levels of carbon monoxide around the star.

Researchers are worried as global warming is rapidly melting Totten Glacier atop East Antarctica. It may raise ocean levels by two metres, which could be the “tipping point” of no return.

Queensland Environment Minister Steven Miles refused to consider coal dust as the main threat to the Great Barrier Reef. He reassured people of the strict shipping procedures the state follows.

Molecules in White Rock sea snail eggs not only can tackle normal cancer, but also uterine sarcomas and resistant lymphomas that require the painful chemotherapy.

Europa and Enceladus may melt into ocean moons and any life-form, if at all they are hidden or trapped beneath the icy moons, may come to life in five billion years.

Humans and animals in the ocean emit an electric field with every flick of fin or twitch of a muscle. Sharks are able to detect the electric field while searching for prey.

Carbon dioxide levels breaching the 400ppm mark signifies a rising emissions problem, and the rate at which greenhouse gas emissions are rising is a matter of serious concern.

If the mangroves keep dying, shorelines will erode, sediment will become mobilised and will redeposit elsewhere. Soon the entire ecosystem would be disrupted and smaller fish won’t have a safe habitat.

A 9.0 magnitude earthquake in the Aleutians may strike in the next 50 years and it would trigger a tsunami that may destroy Hawaii completely.

After scientists discovered the extra teeth in the beaked whale, they appealed to fellow colleagues across the world, including Smithsonian Institute in the US. No one could arrive at an answer.

For the first time scientists found a way to sample the chemistry of ancient Earth's upper atmosphere. Surprisingly, the sampling indicated much higher concentrations of oxygen than expected.

New data from Swarm satellites suggest how changes in magnetic field of Earth may determine how space events such as solar storms will affect life in future.

This new study has debunked popular theories that associate full moon with depression, psychotic episodes, dog bites, car accidents and suicide.

SOFIA soars on a plane 45,000 feet above Earth. The discovery of atomic oxygen is immensely exciting as Mars is considered human’s potential new home.

As the sun was 20 percent less luminous 2.7 billion years ago, earth would have been covered in ice if it had similar atmospheric conditions prevailing now. Still, life prevailed.

In March, NASA scientist James Hansen, who is well-known for his studies on climate change, estimated that in the coming century, sea levels may rise by seven metres.

Researchers from Columbia University have suggested various measures to combat doomsday, such as uploading human minds to machines or altering earth’s orbit by launching an asteroid.

As anthropoid primates, from whom monkeys, apes and humans came, first appeared in Asia, it is important to understand their fate on the continent to find out more about human evolution.

Early earth’s oceans were bombarded by large meteors, comets and asteroids, which were responsible for planting the seeds of life that then took root after certain hydrothermal systems started operating.

Director of ARC Centres of Excellence, professor Terry Hughes, is vigorously spreading awareness on the condition of the Great Barrier Reef and criticising authorities for not taking appropriate actions.

Shark policy expert Christopher Neff wants makers of the technology to study the total ecological impact of the cable. However, he is pretty upbeat about the new shark deterrent cable.

Inside the Martian chamber, the melting ice produced liquid water that boiled energetically. It flowed down the slopes and then filtered into the sand.

The cable is harmless to humans and sharks and floats just under the ocean surface. The cable works electronically and it confuses sharks’ sensory system.

In 2013, IceCube scientists said that they had detected two neutrinos coming from outside our galaxy and unimaginably energetic. Now, the source of such extragalactic neutrinos may have been revealed.

To verify their results, the scientists compared the 2-billion years old crystals to crystals that are much more ancient (more than 4 billion years old). The hypothesis proved right.
