Does Low-Skilled Immigration Hurt the U.S. Economy? Assessing the Evidence

In a report by MPI's Labor Markets Initiative, noted economist and Georgetown University Public Policy Institute Professor Harry J. Holzer examines the economic reasoning and research on these questions and looks at the policy options that shape the impact of less-skilled immigration on the economy. The discussion is on what policy reform would best serve native-born American workers, consumers, and employers, as well as the overall U.S. economy.

Legal Immigration Policies for Low-Skilled Foreign Workers

The current U.S. legal immigration system includes few visas for low-skilled workers, and employers have relied heavily on an unauthorized workforce in many low-skilled occupations. This issue brief explains the questions that policymakers must grapple with when designing programs for admission of low-skill workers, for temporary as well as permanent entry. The brief focuses in part on the recent agreement by the U.S. Chamber of Commerce and AFL-CIO regarding admission of future low-skilled workers.

A neural pathway that erases memories

The discovery of an inhibitory memory circuit could lead to novel treatments for conditions such as PTSD

In order to remember, we must forget. Recent research shows that when your brain retrieves newly encoded information, it suppresses older related information so that it does not interfere with the process of recall. Now a team of European researchers has identified a neural pathway that induces forgetting by actively erasing memories. The findings could eventually lead to novel treatments for conditions such as post-traumatic stress disorder (PTSD).

We’ve known since the early 1950s that a brain structure called the hippocampus is critical for memory formation and retrieval, and subsequent work using modern techniques has revealed a great deal of information about the underlying cellular mechanisms. The hippocampus contains neural circuits that loop through three of its sub-regions – the dentate gyrus and the CA3 and CA1 areas – and it’s widely believed that memories form by the strengthening and weakening of synaptic connections within these circuits.

How the Zika virus causes birth defects

New research provides the first direct evidence that Zika virus causes severe birth defects, and explains exactly how it does so

“I lifted up my T-shirt to check on what I thought had just been a small heat rash,” writes BuzzFeed correspondent Ali Watkins. “It had shown up along the right of my back, extending out from a handful of mosquito bites I had picked up… it had seemed relatively tame [but] now, it was inching across the front of my stomach and down my legs... Meanwhile, my right eye was inflamed and bright red, almost akin to a busted blood vessel.”

Watkins is describing the symptoms of a Zika virus infection that she contracted on a recent trip to Mexico. For many people, infection with this mosquito-borne virus causes an illness with symptoms just like those experienced by Watkins: fever, skin rash, joint pain and conjunctivitis. For others, these symptoms are so mild that they go completely unnoticed.

Tarantula toxin untangles pain pathways

A toxin isolated from the Togo starburst tarantula provides new insights into pain mechanisms and could lead to new treatments for irritable bowel syndrome

With their large, hairy bodies and long legs, tarantulas are an arachnophobe’s worst nightmare. For pain researchers, however, these outsized spiders are a dream come true: Their venom contains a cocktail of toxins, each of which activates pain-sensing nerve fibres in different ways, and researchers in the United States have now identified one such toxin that will help them to better understand pain, and could also lead to treatments for the chronic pain associated with irritable bowel syndrome.

Physical pain signals are transmitted from the body to the brain by specialised sensory neurons called nociceptors. These pain-sensing neurons have cell bodies located just outside the spinal cord, and possess a single conductive fibre that splits in two, with one branch extending out towards the skin surface, and the shorter one entering the back of the cord.

Barack Obama Blindness: Failing to see the unexpected

New research demonstrates an extreme form of inattentional blindness in which we fail to see the unexpected

There’s much more to visual perception than meets the eye. What we see is not merely a matter of patterns of light falling on the retina, but rather is heavily influenced by so-called ‘top-down’ brain mechanisms, which can alter the visual information, and other types of sensory information, that enters the brain before it even reaches our conscious awareness.

Obesity alters brain structure and function

It’s not just your waistline that suffers as you put on weight. Researchers are beginning to find puzzling new links between obesity, memory loss and dementia

Lucy Cheke and her colleagues at the University of Cambridge recently invited a few participants into her lab for a kind of ‘treasure hunt’.

The participants navigated a virtual environment on a computer screen, dropping off various objects along their way. They then answered a series of questions to test their memory of the task, such as where they had hidden a particular object.

Breathing modulates brain activity and mental function

New research shows that the rhythm of breathing directly impacts neural activity in a network of brain areas involved in smell, memory and emotions

The rhythm of breathing co-ordinates electrical activity across a network of brain regions associated with smell, memory, and emotions, and can enhance their functioning, according to a new study by researchers at Northwestern University. The findings, published in the Journal of Neuroscience, suggest that breathing does not merely supply oxygen to the brain and body, but may also organise the activity of populations of cells within multiple brain regions to help orchestrate complex behaviours.

Face-selective brain region continues to grow in adulthood

New findings challenge our understanding of how the brain matures

Faces are important to us. From the moment we are are born, we prefer to look at faces than at other, inanimate objects, and, being social animals, we encounter faces every day of our lives. The face is the first thing we look to when identifying other people; faces also convey emotions, informing us of peoples’ mood, and from them we can usually determine a person’s sex and, sometimes, roughly how old they are. Eye movements can also reveal to us something about another person’s intentions.

Sleep may help us to forget by rebalancing brain synapses

New research provides evidence for the idea that sleep restores cellular homeostasis in the brain and helps us to forget irrelevant information

We spend one third of our lives sleeping, but we still do not know exactly why we sleep. Recent research shows that that the brain does its housekeeping while we sleep, and clears away its waste. According to another hypothesis, sleep plays the vital role of restoring the right balance of brain synapses to enhance learning, and two studies published in today’s issue of Science now provide the most direct evidence yet for this idea.

We do know that sleep is important for consolidating newly formed memories. During waking hours, we learn all kinds of new information, both consciously and unconsciously. To store it, the brain modifies large numbers of synaptic connections, making some of them stronger and larger, and it’s now thought that as we sleep other synapses are weakened or destroyed, so that the important new information is stored for later use, while irrelevant material, which could interfere with learning, is not.

How to become a super memorizer – and what it does to your brain

New research shows that we can train our brains to become memory champions

To many of us, having to memorize a long list of items feels like a chore. But for others, it is more like a sport. Every year, hundreds of these ‘memory athletes’ compete with one another in the World Memory Championships, memorising hundreds of words, numbers, or other pieces of information within minutes. The current world champion is Alex Mullen, who beat his competitors by memorizing a string of more than 550 digits in under 5 minutes.

You may think that such prodigious mental feats are linked to having an unusual brain, or to being extraordinarily clever. But they are not. New research published in the journal Neuron shows that you, too, can be a super memorizer with just six weeks of intensive mnemonic training, and also reveals the long-lasting changes to brain structure and function that occur as a result of such training.

Researchers develop non-invasive deep brain stimulation method

Researchers at MIT have developed a new method of electrically stimulating deep brain tissues without opening the skull

Since 1997, more than 100,000 Parkinson’s Disease patients have been treated with deep brain stimulation (DBS), a surgical technique that involves the implantation of ultra-thin wire electrodes. The implanted device, sometimes referred to as a ‘brain pacemaker’, delivers electrical pulses to a structure called the subthalamic nucleus, located near the centre of the brain, and effectively alleviates many of the physical symptoms of the disease, such as tremor, muscle rigidity, and slowed movements.

DBS is generally safe but, like any surgical procedure, comes with some risks. First and foremost, it is highly invasive, requiring small holes to be drilled in the patient’s skull, through which the electrodes are inserted. Potential complications of this include infection, stroke, and bleeding on the brain. The electrodes, which are implanted for long periods of time, sometimes move out of place; they can also cause swelling at the implantation site; and the wire connecting them to the battery, typically placed under the skin of the chest, can erode, all of which require additional surgical procedures.

[ Wrestling ] Open Question : Do you think The Rock is a 1990s, 2000s or 2010s wrestler in the WWF/E ?

I think The Rock is a combination of both but barely because when he made his debut in the WWF in late 1996, he wasn't even called The Rock yet he was Rocky Maivia at that time. By the time he started getting over with the fans as The Rock, the 90s were almost over because it was 1998 - 99 by then. He spent more time as The Rock in the 2000s but even though he was still in the WWF/E when the decade started, he was gone by 2004 (by then he was already doing movies and wrestling at the same time). Then The Rock stopped wrestling completely and spent the rest of the 00s decade making movies, he spent even less time wrestling in the 2010s which is his most recent run in the WWE he missed 2010, came back in 2011 and was gone by 2013 aside from one match in 2016. What do you guys think ?
