Researchers find link between changes in brain chemistry and SIDS

Researchers find link between changes in brain chemistry and SIDS

A new study conducted by a team of researchers at University of Adelaide has confirmed that there is a strong link between abnormalities in a common brain chemical and sudden infant death syndrome (SIDS). The researchers examined 41 cases of deaths related to SIDS and found striking abnormalities in chemical serotonin in the brains of the victims.

Serotonin, which is also known as 5-HT, is a neurotransmitter in the central nervous system and many other parts of the human body. It plays several roles, including regulation of sleep and control of the cardiovascular system.

Researchers make breakthrough in treatment of childhood peanut allergy

Researchers make breakthrough in treatment of childhood peanut allergy

A team of Australian researchers has made a breakthrough in the treatment of childhood peanut allergy, providing a ray of hope for a possible cure.

A small but long-term clinical trial at the Murdoch Childrens Research Institute found that nearly 66 per cent of the kids who were treated with an experimental immunotherapy treatment got rid of their allergy.

The children’s tolerance to peanuts was found to persist for up to 4 years after they were given the experimental immunotherapy.

Scientists identify sea creatures that left a Melbourne teen unable to walk

Scientists identify sea creatures that left a Melbourne teen unable to walk

Museums Victoria scientists have finally identified the sea creatures that left a Melbourne teenager bloodied and unable to walk.

Sam Kanizay, 16, suffered unexpected wounds to his feet as well as lower legs when he went into the water at Brighton Beach last Saturday to cool down following a footy match.

He said the wounds and injuries were a “freak” incident for him. He received a biopsy in addition to numerous stitches.

Human arrival in Australia pushed back by 18 thousand years

Human arrival in Australia pushed back by 18 thousand years

A new analysis of ancient tools by a team of archaeologists from the University of Queensland has suggested that humans left Africa and arrived in Australia far earlier than previously thought.

It has long been thought that modern humans or Homo sapiens existed on the African continent as far back as 200,000 years ago; and early humans arrived in Australia arrived nearly 47,000 years ago.

Scientists find several new species in deep water off Australian Coast

Scientists find several new species in deep water off Australian Coast

A team of international scientists has discovered a number of new marine species in one of the most unexplored ecosystems in the world, the deep water off Australia.

More than three dozen scientists, including some from Museums Victoria and the CSIRO, explored on the dark abyss with crushing environment nearly 4000 meters below the surface using a vessel named Investigator.

During the one-month expedition, the Investigator visited a total of seven Commonwealth marine reserves from the Freycinet Peninsula to the Coral Sea off Queensland.

Remote Island found littered with plastic debris

Remote Island found littered with plastic debris

A new study by a team of Australian and British researchers has revealed that a remote, uninhabited island in the South Pacific has the world’s worst plastic rubbish density.

The researchers found an estimated 37.7 million pieces of rubbish on the beaches of Henderson Island, which is part of the United Kingdom’s Pitcairn Islands group.

Researchers discover first evidence of life on land

Researchers discover first evidence of life on land

Fossil evidence of early life discovered decades ago in old hot spring deposits in the Pilbara area of Western Australia is expected to shed more light on the evolution of early life on Earth.

After making a fresh analysis of the fossil, researchers estimated that the fossil evidence dates back almost 3.48 billion years. The estimated date of the fossil extends the previous known evidence of life at land-based hot springs on our planet by nearly 3 billion years.

Mass bleaching events offer low prospect of recovery for Great Barrier Reef

Mass bleaching events offer zero prospect of recovery for Great Barrier Reef

Mass bleaching events occurred just twelve months apart offer zero prospect of recovery for the Great Barrier Reef in north Queensland, scientists have warned.

The Great Barrier Reef suffered two consecutive massive coral bleaching events, in 2016 and 2017. A team of scientists from the Australian Research Council’s Centre of Excellence for Coral Reef Studies conducted aerial surveys of the structure, and found that the bleaching events damaged a 1,500km stretch of the reef.

Cyclone Debbie impacts Great Barrier Reef: Report

Cyclone Debbie makes devastating blow to Great Barrier Reef

After suffering back-to-back severe coral bleaching, the Great Barrier Reef has had to cope with another devastating blow — Cyclone Debbie. Ferocious winds moving at speeds of up to 260 kilometer per hour tore through the Whitsunday Islands and made landfall at Airlie Beach. Local researchers and reporters went underwater to examine the destruction caused by the cyclone.

The cyclone snapped off branches and lifted up and threw aside massive pieces of coral. Local tour operators portrayed a disheartening picture of the broken reef.

Coral bleaching affected two-thirds of Australia’s Great Barrier Reef: Study

Coral bleaching affected two-thirds of Australia’s Great Barrier Reef: scientists say

New aerial surveys have confirmed that back-to-back coral bleaching events have affected more than two-thirds of Australia’s Great Barrier Reef.

A team of scientists with the Centre of Excellence for Coral Reef Studies at the Australian Research Council conducted the surveys, and scored bleaching at 800 individual coral reefs across 8,000 kilometers at the world’s biggest living structure.

The results proved that two mass bleaching events that took placed in the recent years have affected a 1,500-kilometer stretch, leaving merely the southern part of the reef unscathed.
