  A researcher puts stickers on a lazy Susan under some plastic cups, then offers a whirl. A preschooler must find hidden stickers when the spinning ends. Some kids remember where the stickers are, but some have to search each cup. The game measures working memory , one of the group of behavioral abilities known as executive control that can be compromised in early-life trauma-facing adolescents. Adversity wreaks havoc, and from there you have a mechanism that reacts differently, says Megan Gunnar, a developmental psychobiologist at Minnesota University in Minneapolis who spent two decades researching the effects of early-life adversity in adopted kids. This work focuses on acute hardship, such as being orphaned, rather than regular struggles, which may teach valuable resilience. An infancy marked by deprivation, neglect or violence may also change the neuroendocrine system governing how the body reacts to stress. Stress response issues will put children on a road to devel...

At a recent conference held on the evolution of infectious diseases, pathologist Nissi Varki, University of California, San Diego ( UCSD), observed that humans suffer from a long list of fatal diseases — including typhoid fever, cholera, mumps, whooping cough, measles, smallpox, polio, and gonorrhea — that don't bother chimpanzees and most other mammals. Both these bacteria follow the same mechanism to get into our cells: they target sugar molecules called sialic acids. Hundreds of millions of these sugars study the outer surface of any cell in the human body — and human sialic acids differ from apes. Varki and an international research team have now studied how nature could have struggled to develop new defenses after molecular instability appeared in our distant ancestors. Through studying current human genomes and ancient DNA from our extinct ancestors, Neanderthals and Denisovans, the researchers found an evolutionary explosion of our immune cells that happened at least ...

China named a hard-line figure to lead Hong Kong 's newsecurity agency. Zheng Yanxiong is best known for his role in dealing with a land dispute protest in Wukan, southern China. The new organization, responding directly to Beijing, is set up in Hong Kong this week to implement a draconian security law. Regulation critics claim it erodes territorial freedoms. With up to life in prison, the law opposes secession, subversion and terrorism. Many leading pro-democracy activists have abandoned their positions and one of them, once student leader and local legislator Nathan Law, has fled the region. Separately, one of ten people arrested during demonstrations on Wednesday has been the first to be convicted under the new legislation. Hundreds were arrested in clashes. The motorcyclist was charged with promoting secession and extremism, accused of riding into a group of police while holding a banner calling for Hong Kong 's independence. Beijing has rejected critici...

Envyalters individual behavior and, consequently, strategies of a person in characteristic ways. Due to changed behavior, two separate social classes arise. Differences in cement class history and education are widely known. It is not clear when and under what circumstances individual psychological forces will separate and separate an initially homogeneous social group. Claudius Gros, professor of theoretical physics at the University of Goethe, investigated this issue mathematically precisely using game theory methods which means that everyone optimizes their success by predetermined rules. I wanted to find out if social differences can emerge alone if no one starts with advantages – that is, if all actors have the same skills and opportunities, "explains the physicist. The study is based on the assumption that things are coveted but limited in every society, such as jobs, social contacts, and power positions. If the top position is already occupied, an inequality is cre...

Although infinite foods, nutrients, and methods for meal-replacement claim to ensure rapid weight loss, most lack empirical evidence. However, science-backed solutions affect weight management. Such techniques include exercise, keeping track of calorie consumption, extended fasting, and reducing dietary carbohydrates. In this article, we find nine useful weight-loss methods. Scientific-backed weight-loss Weight loss methods supporting scientific research include:       1.   Fasting intermittently 2.     Tracking and exercising 3.     Eat attentively 4.     Eat breakfast protein 5.     Reducing sugar and processed carbohydrates 6.     Eat plenty of fiber 7.     Balancing intestinal bacteria 8.     A good night's sleep 9.     Manage your stress levels Fasting intermittently         Alternat...

For more than three decades, China's ruling Communist Party experienced one of the greatest political crises. A rapidly spreading outbreak of the new coronavirus was a "huge danger and threat" to social stability, Chinese President Xi Jinping cautioned top party officials in a later publicly-published internal address. Yet with new domestic infections near zero, China declared victory over a virus that is still struggling to curb. Newly optimistic and prone to criticism that it initially covered up the outbreak, China's leadership is now trying to recast the pandemic as a political victory by claiming that its centralized, top-down government structure made it ideally suitable for controlling and handling the virus; official figures estimate the virus claimed less than 5,000 lives in China. The way the Chinese treated the coronavirus is combined with technology, culture and very efficient policy collaboration, "said Wang Huiyao, president of China and G...

See the destiny: attackers can get between brain waves and hospital kit and it will get worse, IOActive senior consultant Alejandro Hernández said. Hernández says that the potential to copy, modify and delete brain waves used in electroencephalography ( EEG) has already emerged, the kit has already been hacked and the healthcare sector has taken little steps to better protect captured brain waves. After decades in laboratories and hospitals, encephalography is introduced in lightweight electronic headphones and other tools that are still largely experimental or gimmicky. Clinically, EEG recording devices are a useful tool for diagnosing seizures and sleeping disorders like narcolepsy. Researchers believe recorded brain waves have the potential to score murderers' mental abilities, create brain-to-brain interfaces where conscious thoughts are transmitted over the internet and unconsciously enacted by another person, or see neural-impulse-flown drones. Before we get the...
