Major events not necessary to explain oxygen-rich Earth, study finds

Scientists at the University of Leeds in England simulated the early Earth's atmosphere on a computer, in an attempt to explain the Great Oxidation Event, which occurred 2.4 billion years ago and greatly increased oxygen levels on Earth, and ultimately allowed for life to evolve. The simulation suggests that gradual changes in nutrient cycles alone may have been responsible for the oxygen-richness, not necessarily a large event.

New study reveals record 3.8 trillion tons of ice lost in Greenland

Researchers participating in the Ice Sheet Mass Balance Inter-comparison Exercise, a global collaboration between scientific institutions aimed at studying ice sheet levels, found that the Greenland ice sheet has lost 3.8 trillion tons of ice since 1992, at a rapidly accelerating pace. Consequently, sea levels have risen by 10.6 mm, and researchers state the world is heading for the extreme end of the climate change scenario.

Electric charge may have been key ingredient in planet formation, experiment finds

Researchers have struggled to explain the mechanisms of planet formation from protoplanetary dust particles, due to the "bouncing barrier", which prevents particles from forming a planet under the force of gravity. A new experiment used tiny glass beads as a replacement for dust particles, and found that in a weightless environment, the particles came together due to differences in electric charge, sometimes in clumps of thousands.

DNA coding by Harvard scientists might immunize human software from all diseases

A team of scientists at Harvard led by leading biologist George Church has found ways to edit human DNA like code. The team is currently working on making humans immune to all diseases and reversing the aging process although they claim it will take at least another ten years before any of their breakthroughs are available to humans.

New membrane invention for hydroelectricity produces more power than nuclear plants

A new invention that utilizes the differences in electric potential between freshwater and seawater has been shown to have great potential, if researchers can find a method to manufacture it on an industrial scale. The "blue energy" membrane generates power at places where a river flows into the sea, and has an estimated global potential of 2.6 terawatts of power, equivalent to the power of 2000 nuclear plants.

50-year-old climate models were still surprisingly accurate, research finds

Climate scientist Zeke Hausfather recently concluded a study where his team studied the predictions made by climate models stretching as far back as 1970, almost fifty years ago. They found that the models were incredibly accurate, with the oldest one having the highest accuracy, 91 percent, with the average accuracy score for each model at 69 percent. Hausfather hopes the study will ease criticisms of the inaccuracies of climate models.

Scientists from The International Union for the Conservation of Nature have released a report that claims the world's oceans are losing oxygen at an unprecedented rate due to both climate change and an increase in fish farming. Large fish such as sharks and tuna require more oxygen in order to survive and are now at risk.

'Junkyard' experiment reveals single-celled organism to be surprisingly intelligent

Scientists decided to recreate a century-old experiment by zoologist Herbert Jennings, which had revealed that single-celled organisms called stentors had displayed unusually intelligent behavior in trying to avoid some irritants that had been placed near them. The experiment had long been dismissed, since no research had ever reproduced it, but a casual experiment by Harvard researchers has managed to successfully produce Jennings' original results.

Plants may emit high frequency 'screams' when in distress

Researchers at the Tel Aviv University in Israel conducted experiments on tobacco and tomato plants, creating two different kinds of distressing situations: one in which they were deprived of water, another when their stem was cut. They placed highly sensitive audio recorders near the plants and found that the plants not only emitted ultrasonic sounds when distressed, but also emitted different sounds for different kinds of situations.

A study of 70 dogs organized at the University of Surrey, UK by researcher Holly Root-Gutteridge has found that their ability to recognize words is more advanced than expected. The study presented the dogs with several simple words, spoken by unfamiliar voices in different pitches, that had a difference of only one vowel. 48 out of the 70 dogs were shown to recognize the differences between the words.

Bubonic plague was not as devastating as previously thought, scientists say

Textbooks have historically considered an outbreak of bubonic plague (also known as the Black Death), during the era of Roman emperor Justinian, to have wrought chaos in the region, causing millions of deaths and the fall of several empires. However, latest research has convinced scientists that the effects of the plague may have been overstated, and that it did not cause political collapse, in Rome or elsewhere.

The fossil consists of a duck-billed hadrosaur's jaw bone, with a blob of amber carrying insects and plant life. and would have resulted when the dead hadrosaur's jawbone was carried into the river and a tree's resin fell on top of it, hardening into amber over the years.
