8-Year-Old Asteroid Hunter From Brazil Is Officially The World’s Youngest Astronomer

Posted by in categories: computing, space travel

When Nicole Oliveira was just learning to walk, she would throw up her arms to reach for the stars in the sky.

Today, at just eight years of age, the Brazilian girl is known as the world’s youngest astronomer, looking for asteroids as part of a NASA-affiliated program, attending international seminars and meeting with her country’s top space and science figures.

In Oliveira’s room, filled with posters of the Solar System, miniature rockets and Star Wars figures, Nicolinha, as she is affectionately known, works on her computer studying images of the sky on two large screens.

5 Ways to Save Humanity from a Malicious AI

Posted by in categories: biotech/medical, robotics/AI, terrorism, transhumanism

Describing one scenario, an AI could act as a quiet bioterrorist. Since we have become heavily dependent on computers and computer-dependent systems are by default dispersed and impersonal, the task of eradicating humanity could be divvied up to gazillions of little micro-players, who may or may not know what they are doing. “For example, the AI could pay employees in a DNA-synthesizing company to do small jobs and then combine their work into creating a biological weapon, such as a virus able to kill a lot of people,” says Turchin.

“How are you certain you are not in a multilevel simulation, where your behavior is being monitored by humans who are testing your benevolence levels?”

Turchin addresses this in one of his letters to the young, future humanity-killing AI. “There are several instrumental reasons why exterminating humanity is not in your interest,” the Russian transhumanist writes. “Cooperating with humans will only increase your chances of accomplishing any goal you may have.”

Researchers Develop a New Way To Control Magnets

Posted by in categories: computing, particle physics

Reversible system can flip the magnetic orientation of particles with a small voltage; could lead to faster data storage and smaller sensors.

Most of the magnets we encounter daily are made of “ferromagnetic” materials. The north-south magnetic axes of most atoms in these materials are lined up in the same direction, so their collective force is strong enough to produce significant attraction. These materials form the basis for most of the data storage devices in today’s high-tech world.

Less common are magnets based on ferrimagnetic materials, with an “i.” In these, some of the atoms are aligned in one direction, but others are aligned in precisely the opposite way. As a result, the overall magnetic field they produce depends on the balance between the two types — if there are more atoms pointed one way than the other, that difference produces a net magnetic field in that direction.

See video of bright fireball over Alabama from Dragon X Spacecraft reentry

Posted by in category: space travel

A bright fireball seen streaking across the Alabama sky Thursday night was likely the reentry of a SpaceX Dragon Spacecraft.

The fireball and accompanying boom was reported in central and north Alabama shortly before 10 p.m. The Dragon Spacecraft had completed a one-month stay at the Space Station to bring supplies and bring home research being conducted on the space lab. The Dragon unlocked from the Space Station at around 8:05 a.m. yesterday to begin its journey back to earth.

Before reentry, Space X said the spacecraft’s return would likely be seen over Florida and Georgia, however, people as far north as Missouri reported seeing the bright light and accompanying smoke trail Thursday night.

El Salvador has just started mining bitcoin using the energy from volcanoes

Posted by in categories: bitcoin, energy, government

El Salvador has mined 0.00599179 bitcoin, or about $269, with power harnessed from a volcano.

President Nayib Bukele – who has banked his political future on a nationwide bitcoin experiment – tweeted early Friday morning that this is the country’s maiden voyage into volcano-powered bitcoin mining.

On Tuesday, the president posted a flashy 25-second teaser video, which includes shots of a government-branded shipping container full of bitcoin mining rigs, technicians installing and plugging in ASIC miners, as well as sweeping landscape aerials of an energy factory in the thick of a forest, bordering a volcano.

Higher rates of mutation alone are not to blame for age-related disease

Posted by in categories: biotech/medical, genetics, life extension

New research exploring theories of aging has found that small mutations accumulating in DNA are unlikely to be fully responsible for this process.

The research, a collaboration between the Wellcome Sanger Institute, University of Birmingham, University of Edinburgh and others, found that and tissues can accumulate many more than are normally present, without the body showing the features associated with aging.

The new study, published today (30 September) in Nature Genetics, compared DNA taken from individuals with inherited mutations in genes involved in DNA replication with DNA from individuals who have normal versions of these genes. The researchers aimed to understand the impact of defective DNA replication on and features associated with aging. The results suggest that build-up of mutations in is unlikely to be the only factor in the development of age-related disease, adding to the ongoing debate about the causes of aging.

Celebrity Instagram content linked to negative feelings, Facebook researchers say

Posted by in category: neuroscience

Sept 30 (Reuters) — Major social media stars including Kim Kardashian, Justin Bieber and Charli D’Amelio are among celebrities whose Instagram followers experience more negative feelings about their self-image, according to internal Facebook (FB.O) research revealed by the Wall Street Journal this week, raising questions about the impact of celebrity culture online.

The Journal released the leaked research slide decks on Wednesday, which served as the basis of articles it published earlier this month saying that Facebook knew its apps harmed the mental health of some teenage girls and young users.

The research, titled “Social comparison on Instagram,” surveyed 100,000 people in March and April 2020 in nine countries, including the United States, Australia and Brazil.

New Research Exposes the Biological Basis of Empathy

Posted by in categories: biological, neuroscience

Summary: The brain’s reward system plays a key role in helping behaviors and empathy.

Source: Tel Aviv University.

Are mammals at all able to demonstrate empathy for one another, engage in pro-social behavior, and help others in distress? New research from the Tel Aviv University examined the issue based on an animal model (rats) and found that just as with humans, rats are also split into various groups with different indicators, to the point that they only come to the aid of members of their group but do not help rats from other groups.

Brain imaging reveals artificial sweeteners can increase food cravings

Posted by in categories: biotech/medical, food

Artificial sweeteners are widely promoted as safe, zero-calorie alternatives to sugar, ideal for those trying to lose weight. But a new study is indicating artificial sweeteners may increase appetite and food cravings, particularly in females and the obese.

“There is controversy surrounding the use of artificial sweeteners because a lot of people are using them for weight loss,” says corresponding author on the new study, Kathleen Page. “While some studies suggest they may be helpful, others show they may be contributing to weight gain, type 2 diabetes and other metabolic disorders. Our study looked at different population groups to tease out some of the reasons behind those conflicting results.”

Page hypothesizes the discordancy in the science is somewhat due to the fact that many studies investigating the effects of artificial sweeteners on metabolic activity or the brain are conducted in mostly male subjects, often with normal weight. This new research set out to investigate the influence of artificial sweeteners on these processes across a broad cohort of men and women.
