The dangers of green house gases

Summary:
Despite reports that global emissions of the potent greenhouse gas were almost eliminated in 2017, an international team of scientists has found atmospheric levels growing at record values.

Plants are at a greater risk due to climate change

Summary:
Scientists think that current models are incomplete and that we may be underestimating crop losses. A new study shows that infested tomato plants, in their efforts to fight off caterpillars, don't adapt well to rising temperatures. This double-edged sword worsens their productivity.

Oldest Asteroid Striking Earth

Summary:
Scientists have discovered Earth's oldest asteroid strike occurred at Yarrabubba, in outback Western Australia, and coincided with the end of a global deep freeze known as a Snowball Earth. The research used isotopic analysis of minerals to calculate the precise age of the Yarrabubba crater for the first time, putting it at 2.229 billion years old -- making it 200 million years older than the next oldest impact.

How is climate change reshaping the world

Summary:
A new study uses machine learning to project migration patterns resulting from sea-level rise. Researchers found the impact of rising oceans will ripple across the country, beyond coastal areas at risk of flooding, as affected people move inland. Popular relocation choices will include land-locked cities such as Atlanta, Houston, Dallas, Denver and Las Vegas. The model also predicts suburban and rural areas in the Midwest will experience disproportionately large influx of people relative to their smaller local populations.

How do you measure the temperature of dark matter

Summary:
Warm, cold, just right? Physicists are using gravitational lensing to take the temperature of dark matter, the mysterious substance that makes up about a quarter of our universe.

Uses of Deep Learning

Summary:
Researchers have harnessed the power of a type of artificial intelligence known as deep learning to create a new laser-based system that can image around corners in real time. With further development, the system might let self-driving cars 'look' around parked cars or busy intersections to see hazards or pedestrians.

How oxygen and other elements were formed

Summary:
Astronomers have detected large amounts of oxygen in the atmosphere of one of the oldest and most elementally depleted stars known. This new finding provides an important clue on how oxygen and other important elements were produced in the first generations of stars in the universe.
