Saturday Quote: Increased chance of asteroid attacks. Rainforest Resilience; Animal Awareness

This week, researchers at Ferrera University reported on the evolution of skin, eyes and hair pigmentation in Europe over the past 45,000 years. A reexamination of Galileo space probe data strongly suggests that Callisto has an underground sea. Also, two-dimensional carbon materials are reportedly more difficult than graphene, and are resistant to cracking.

Plus, this week there was a possibility that an asteroid bound to Earth could hit the planet. Researchers reported that Amazon is more resilient than previously believed. And scientists and philosophers have jointly developed a new approach to exploring animal consciousness.

Nihilist emotions are rising slightly

Good News from NIHILIST – NASA reports that the likelihood of the 2024 TR4, the Earth’s asteroid 2024, has risen to 3.1% in 2032. But it is a real mixed bag for people standing on the grass with their arms stretched out, waiting for a space hammer. Its size ranges from 130 to 300 feet, making it a “city killer” rather than a “planet killer.”

Essentially, you need to be in the right place to be wiped out by a huge shock wave. Furthermore, the likelihood of a strike is likely to rise as astronomers track their approach. This was the case in 2004 with the asteroid Apophis. Before continuing the pursuit, there was a 2.7% chance of hitting the Earth.

On the positive aspect of the ledger (if you are a nihilist), the current 3.1% chance of an Earth shock sets a new record. NASA says the danger it poses is its speed, not its size. One estimate suggests that the TR4 could hit the atmosphere at 40,000 mph. With a force of about 8 megatons, it can explode at airbursts well above ground level. Astronomers have not ruled out the possibility of impact craters.

The likelihood of impact is likely to decrease with further observation, but NASA says that if they rise to 10%, the International Asteroid Warning Network will begin terrestrial preparations for all UN members in the threatened region. They say they will issue formal warnings and recommendations to do so. “

The rainforest is still damp

Previously, ecologists believed in the “tumbling point” argument that deforestation reduces the evapotranspiration of water from the soil to the atmosphere and causes a decrease in rainfall. Now, in new research, researchers are challenging this hypothesis. Noting that previous modeling research supported the “twilight” argument, scientists at the Max Planck Meteorology Institute addressed important limitations. These studies were based on a global climate model using a simplified representation of convection. It is often applied to large-scale atmospheric circulation.

Instead, researchers construct the first global simulations to use the global storm-removing icon model, and instead of the simplified models of convection built into previous research, they explicitly make convection It’s resolved. They found that Amazon precipitation is less dependent on evapotranspiration than researchers once thought. Evaporation decreases with deforestation, but this loss is compensated by large-scale cyclical changes. According to the new model, average annual rainfall does not change significantly in the Amazon, even after deforestation.

Slippery topics

Philosophers are the nuisance of scientific research to clarify the ethical domains occupy by legitimate research and provide new approaches to address slippery topics that scientists still struggle with. You may be involved in the initiative. One major example is the existence of animal consciousness. An international group of philosophers and scientists have just announced a new approach to understanding the depth of animal consciousness that seeks to shed light on the similarities and differences between living things.

The researchers state that “when humans and other animals act similarly and the best explanation of these behaviors in humans involves conscious experiences, it is considered evidence of conscious experiences in other animals. When there is a possibility.”

They are seeking approaches to identify specific traits of consciousness, such as seeking experiences of pain and evidence that these markers are present in other species. Their approach acknowledges that these types of markers have limitations. It offers a large linguistic model as an example where verbal behavior alone does not provide strong evidence of consciousness.
