the one is not what you will imagine it will be,
it will come when you’re 16 and you’re not looking for love,
when all you want is to pass your maths exam,
it will come on a busy day outside of PE class when she picks up stray pieces of grass and throws it at you,
or when she drops your pen and you fight over who picks it up.
the one will have you questioning what it truly means to be in love,
but don’t think of it as a burden,
because she will teach you the real meaning of the word safety,
she will wipe your wet eyes even when the tears are mirrored in hers,
she will lift you so high that you’re sure you are floating,
and you wouldn’t have it any other way.
the one will not be how you want it to be,
it will be snotty noses and blood curdling sobs into pillows,
it will be making mistakes and asking for second chances,
it will feel like a knife wound sharp to the gut,
but don’t fret because you will take it all just to hear her laugh at her own jokes.
the one will come when all the odds are stacked against you,
when the years turn to months turns to days till you have to leave for your future,
when the space between your bodies turns from a double bed to two cities,
but her crackled voice on the other end of the phone will give you more meaning than 10 years attending church ever could.
the one will come with hardships you didn’t ever think would exist,
but the one will give you shelter from your own broken heart,
and she will capture your heart so completely there is no way you could ever be apart,
so be patient because the one is right around the corner,
she will hop on a plane in a year from now and she will enter your life as the new girl in school,
and you will forget why you ever thought you would be better off alone.
p.s. please talk to her. no, she doesn’t think you’re an idiot.
Scientists say your dog knows better than to trust that bogus happy tone you use for bad news, according to a new study.
Scientists, led by researcher Attila Andics from Eötvös Loránd University in Budapest, found that dogs can differentiate between the way humans say words and what they actually mean. So if you call your dog a good boy, but your tone doesn’t match the words, he’s going to know you’re being dishonest.
In a new report, dozens of scientists, health practitioners and
children’s health advocates are calling for renewed attention to the
growing evidence that many common and widely available chemicals
endanger neurodevelopment in fetuses and children of all ages.
The chemicals that are of most concern include lead and mercury;
organophosphate pesticides used in agriculture and home gardens;
phthalates, which are used in pharmaceuticals, plastics and personal
care products; flame retardants known as polybrominated diphenyl ethers;
and air pollutants produced by the combustion of wood and fossil fuels,
said University of Illinois comparative biosciences professor Susan Schantz, one of dozens of individual signatories to the consensus statement.
Polychlorinated biphenyls, once used as coolants and lubricants in
transformers and other electrical equipment, also are of concern. PCBs
were banned in the U.S. in 1977, but can persist in the environment for
decades, she said.
The new report, “Project TENDR: Targeting Environmental
NeuroDevelopment Risks,” appears in the journal Environmental Health
Perspectives. The group also has a website with information about each of the chemicals of concern.
“These chemicals are pervasive, not only in air and water, but in
everyday consumer products that we use on our bodies and in our homes,”
Schantz said. “Reducing exposures to toxic chemicals can be done, and is
urgently needed to protect today’s and tomorrow’s children.”
Schantz is a faculty member in the College of Veterinary Medicine and in the Beckman Institute for Advanced Science and Technology at the U. of I.
“The human brain develops over a very long period of time, starting
in gestation and continuing during childhood and even into early
adulthood,” Schantz said. “But the biggest amount of growth occurs
during prenatal development. The neurons are forming and migrating and
maturing and differentiating. And if you disrupt this process, you’re
likely to have permanent effects.”
Some of the chemicals of concern, such as phthalates and PBDEs, are
known to interfere with normal hormone activity. For example, most
pregnant women in the U.S. will test positive for exposure to phthalates
and PBDEs, both of which disrupt thyroid hormone function.
“Thyroid hormone is involved in almost every aspect of brain
development, from formation of the neurons to cell division, to the
proper migration of cells and myelination of the axons after the cells
are differentiated,” said Schantz. “It regulates many of the genes
involved in nervous system development.”
Schantz and her colleagues at Illinois are studying infants and their
mothers to determine whether prenatal exposure to phthalates and other
endocrine disruptors leads to changes in the brain or behavior. This
research, along with parallel studies in older children and animals, is a
primary focus of the Children’s Environmental Health Research Center at Illinois, which Schantz directs.
Phthalates also interfere with steroid hormone activity. Studies link exposure to certain phthalates with attention deficits, lower IQ and conduct disorders in children.
“Phthalates are everywhere; they’re in all kinds of different products. We’re exposed to them every day,” Schantz said.
The report criticizes current regulatory lapses that allow chemicals
to be introduced into people’s lives with little or no review of their
effects on fetal and child health.
“For most chemicals, we have no idea what they’re doing to children’s
neurodevelopment,” Schantz said. “They just haven’t been studied.
“And if it looks like something is a risk, we feel policymakers
should be willing to make a decision that this or that chemical could be
a bad actor and we need to stop its production or limit its use,” she
said. “We shouldn’t have to wait 10 or 15 years – allowing countless
children to be exposed to it in the meantime – until we’re positive it’s
a bad actor.”
Hey everyone! I’m trying to act cool but honestly im fREAKING OUT BC I REACHED 1K WHOAAA ASDFGHJKL. *clears throat* Anyway, this is a huge milestone for me since I remade this account and I can’t thank you enough for this gift. <3 So, I’ve seen a couple of people doing it and I totally stole it lol thought it was a great idea to do, too. So here’s my mutual appreciation, tbh it seems to weird that all of you follow me, I don’t deserve you ahh. Thank you so much! <33
Although most neurons are generated during embryogenesis, some regions
of the brain, such as the olfactory bulb in rodents and the hippocampus
in humans, are capable of constantly regenerating their neurons in
adulthood. Scientists first conclusively discovered these new adult
neurons around 15 years ago, but their function remained a mystery,
mainly because they are inaccessible in living animals.
In an article published in the journal Neuron, scientists from the Laboratory for Perception and Memory
at the Institut Pasteur directed by CNRS scientist Pierre-Marie Lledo
provide further evidence of the highly dynamic nature of the changes
observed at the neuronal level in adult brains. The scientists spent
several months observing the development of neurons formed in adulthood
in the olfactory bulbs of mice. This gave them the unique opportunity to
see the formation, stabilization and elimination of connections between
neurons in real time.
They revealed that in the olfactory bulb, where new neurons are
continuously formed, the connections between these new neurons and
neighboring cells are significantly rearranged throughout their
lifetime. All these neurons are constantly reorganizing the billions of
“synaptic” contacts they establish among themselves. The scientists were
surprised by this observation. “We expected to see the synapses
gradually stabilizing, as happens during brain development. But
astonishingly, these synapses proved to be highly dynamic throughout the
life of the new neurons. Also, these dynamics were reflected in the
principal neurons, their primary synaptic partner,” explained first author, Kurt Sailor, from the Institut Pasteur.
To observe the ongoing formation of neuronal circuits, the scientists
marked the new neurons with a green fluorescent protein (GFP), to allow
imaging of the dynamic changes with microscopy. These experiments were
carried out over a period of several months to follow the entire life
cycle of the new neurons. In the first three weeks of their life, these
new neurons extended their cellular projections, known as dendrites, to
form several ramifications, which subsequently became very stable. They
next observed the neuronal spines, the structure where synapses form,
and demonstrated that 20% of the synapses between new and pre-existing
neurons were changed on a daily basis – a phenomenon that was also
observed in their synaptic partners, the principal olfactory bulb
neurons. Using computer-based models, the authors showed that these
dynamics enabled the synaptic network to adjust efficiently and reliably
to ongoing sensory changes in the environment.
“Our findings suggest that the plasticity of this constantly
regenerating region of the brain occurs with continuous physical
formation and elimination of synaptic connections. This structural
plasticity reveals a unique dynamic mechanism that is vital for the
regeneration and integration of new neurons within the adult brain
circuit,” concluded the scientists. More generally, this study
suggests a universal plasticity mechanism in brain regions that are
closely associated with memory and learning.
