Take a moment to think about how you treat yourself when you make a mistake or fail to reach a goal. If you tend to beat yourself up when things go wrong, you, like most people, can use a little more self-compassion in your life.

Forgiving and nurturing yourself seem to have benefits in their own right. Strong self-compassion can even set the stage for better health, relationships, and general well-being. So far, research has revealed a number of benefits of self-compassion. Lower levels of anxiety and depression have been observed in people with higher self-compassion. Self-compassionate people recognize when they are suffering and are kind to themselves at these times, thereby lowering their own levels of related anxiety and depression.

Some people come by self-compassion naturally, but not everyone does. Luckily, it is a learnable skill. Several methods have been proposed, and training programs are being developed, to help people discover and cultivate their own self-compassion.

Here are four ways to give your self-compassion skills a quick boost:

1: Comfort your body :-
Eat something healthy. Lie down and rest. Massage your own neck, feet, or hands. Take a walk. Anything you can do to improve how you feel physically gives you a dose of self-compassion.

2. Write a letter to yourself :-
Think of a situation that caused you to feel pain (a breakup with a lover, a job loss, a poorly received presentation). Write a letter to yourself describing the situation, but without blaming anyone — including yourself. Use this exercise to nurture your feelings.

3. Give yourself encouragement :-
Think of what you would say to a good friend if he or she was facing a difficult or stressful situation. Then, when you find yourself in this kind of situation, direct these compassionate responses toward yourself.

4. Practice mindfulness : -
Even a quick exercise, such as meditating for a few minutes, can be a great way to nurture and accept ourselves while we're in pain.

By culturing astrocytes, microglia, and neurons—all derived from human-induced pluripotent stem cells—in one dish, researchers have created an effective model to study the cognitive impacts of HIV and other diseases.
Using a newly developed laboratory model of three types of brain cells, Penn and CHOP scientists reveal how HIV infection—as well as the drugs that treat it—can take a toll on the central nervous system.
Though many negative repercussions of human immunodeficiency virus infection can be mitigated with the use of antiretroviral therapy (ART), one area where medical advances haven’t made as much progress is in the reduction of cognitive impacts. Half of HIV patients have HIV-associated neurocognitive disorders (HAND), which can manifest in a variety of ways, from forgetfulness and confusion to behavior changes and motor deficiencies.

Experiments in Mice And Human Cells Shed Light On Best Way to Deliver Nanoparticle Therapy For Cancer

Informer : አስኳላ

Researchers in the cancer nanomedicine community debate whether the use of tiny structures, called nanoparticles, can best deliver drug therapy to tumors passively — allowing the nanoparticles to diffuse into tumors and become held in place, or actively — adding a targeted anti-cancer molecule to bind to specific cancer cell receptors and, in theory, keep the nanoparticle in the tumor longer. Now, new research on human and mouse tumors in mice by investigators suggests the question is even more complicated.

Our body’s ability to detect disease, foreign material, and the location of food sources and toxins is all determined by a cocktail of chemicals that surround our cells, as well as our cells’ ability to ‘read’ these chemicals. Cells are highly sensitive. In fact, our immune system can be triggered by the presence of just one foreign molecule or ion. Yet researchers don’t know how cells achieve this level of sensitivity.

Now, scientists have created a simple model that is providing some answers. They have used this model to determine which techniques a cell might employ to increase its sensitivity in different circumstances, shedding light on how the biochemical networks in our bodies operate.

MOTHER/INFANT SKIN-TO-SKIN TOUCH BOOSTS BABY’S BRAIN DEVELOPMENT

Informer : አስኳላ

As the world prioritizes social distancing to stop or slow down the spread of coronavirus (COVID-19), a new study by researchers at Florida Atlantic University demonstrates that mother-infant touch and contact are essential for optimal neurodevelopmental regulation in early infancy. Kangaroo Care, a skin-to-skin, chest-to-chest method of caring for a baby, especially one who is premature, has been associated with promoting neurophysiological development. This method of caring emphasizes the importance of holding the naked or partially dressed baby against the bare skin of a parent, typically the mother. New research is showing that extended use of Kangaroo Care can positively benefit full-term infants and their mothers during the post-partum period.

A critical enzyme for sperm formation could be a target for treating male infertility

Informer : አስኳላ

while some of our body’s cells divide in a matter of hours, the process of making sperm, meiosis, alone takes about 14 days from start to finish. And fully six of those days are spent in the stage known as the pachytene, when pairs of chromosomes from an individual’s mother and father align and connect.
“This stage is really important, because the pair needs to be aligned for the exchange of genetic material between those two chromosomes,” “If anything goes wrong at this stage, it can cause a defect in meiosis and problems in the resulting sperm, leading to infertility, pregnancy loss, or birth defects.”

In a new paper in Science Advances, Wang and colleagues have identified an enzyme that plays a crucial role in maintaining this chromosomal pairing during the pachytene stage of meiosis. Without this protein, named SKP1, meiosis cannot proceed to metaphase, the next major developmental stage involved in generating sperm cells.

A quantum sensor could give Soldiers a way to detect communication signals over the entire radio frequency spectrum, from 0 to 100 GHz, said researchers from the Army.
Such wide spectral coverage by a single antenna is impossible with a traditional receiver system and would require multiple systems of individual antennas, amplifiers, and other components.

In 2018, Army scientists were the first in the world to create a quantum receiver that uses highly excited, super-sensitive atoms--known as Rydberg atoms--to detect communications signals, a scientist at the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory. The researchers calculated the receiver’s channel capacity, or rate of data transmission, based on fundamental principles, and then achieved that performance experimentally in their lab--improving on other groups’ results by orders of magnitude.

Stroke: When the system fails for the second time

Informer : አስኳላ

After a stroke, there is an increased risk of suffering a second one. Until now, it was known that if areas in the left hemisphere were affected during the first attack, language is often particularly impaired. In order to maintain the language capabilities, the brain usually drives up neighboring areas and briefly also the counterparts on the right side. However, it was unclear whether this would still happen after a second attack, and whether the activation of the right hemisphere areas is supportive for the regeneration at all. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) now found an answer by using virtual lesions. Indeed, it seems that the right hemisphere plays a constructive role in maintenance of function following big lesions as well as repeated strokes. These findings can help to improve therapy for those affected.

The image shows that different vocalization-related neural signals occurring across frontal cortex laminae (left) precede the two types of sounds (right) uttered by bats (species: Carollia perspicillata). The sounds are shown as color-coded time-frequency representations. One example social call is shown in the top right and one example echolocation call in the bottom right.

A particular neuronal circuit in the brains of bats controls their vocalisations. This was recently discovered by biologists at Goethe University Frankfurt. Based on the rhythm with which the circuit oscillated, the Frankfurt researchers were able to predict the kind of sounds the bats were about to make. These research results could contribute to a better understanding of human diseases in which language is impaired such as Parkinson’s or Tourette syndrome.

When parents eat low-protein or high-fat diets it can lead to metabolic disorders in their adult offspring. Now, an international team led by researchers at the RIKEN Cluster for Pioneering Research (CPR) have identified a key player and the molecular events underlying this phenomenon in mice.

The Developmental Origins of Health and Disease is a school of thought that focuses on how prenatal factors such as stress and diet impact the development of diseases when children reach adulthood. Experimental evidence indicates that environmental factors that affect parents do play a role in reprogramming the health of their offspring throughout their lifespan. In particular, parental low-protein diets are known to be related to metabolic disorders in their children, such as diabetes.
