Weight loss Stalled? Kick those Hunger Cravings!
Trying to drop the weight, but find yourself picking up more of it? Is your diet failing because you are so hungry you could eat a horse? Well a new study offers some, maybe obvious, but nevertheless helpful insights to help you wrangle in that waist line. A healthy diet will help you drop the weight, but if you aren’t sure what a healthy diet contains that might be a problem. If you are trying to cut the weight, but can’t fight the hunger you might just need to try beans!
Want a Larger Brain: How About an Implant?
Feel like you could use some extra grey matter? Maybe get a dash of genius added to all those cobwebs in the brain? Well then science might just have the answer. Researchers have managed to graft neurons that were made from reprogrammed stem cells into the brains of mice for the first time with long term stability.The best part, six months after implantation, the neurons had become fully functionally integrated into the brain.
Is Fat Making you… Fat?
Fast food, let’s face it, it’s not the best for you. Yet Mcdonalds and Pizza hut are known practically world wide [although menu options differ]. With the rise of our waist lines and the shrinking cost of fast food, you might suspect a connection. Fortunately for your big mac addiction [no judgement] it isn’t what you might think. If you’re finding it harder and harder to see your toes, you might just have your brain, and not your stomach, to thank for it.
At risk for Cancer? Try Spicy Food!
Like spicy food? Well next time you eat some you should hug that chili pepper, because he might just save your life. This is an interesting find, researchers have found that dietary capsaicin — the stuff that gives chili pepers that spicy burn — produces chronic activation of a receptor on cells lining the intestines of mice, which just happens to trigger a reaction that ultimately reduces the risk of colorectal tumors [a fancy way of saying tumors in the intestinal tract].
Possible treatment and Prevention for Parkinson’s
From the Michael J Fox Foundation for Parkinson’s Research — you can donate by clicking the link.
Parkinson’s disease affects neurons in a particular brain region, when it develops brain cells have their mitochondrial activity cease and then the cells die. But now researchers have shown that supplying D-lactate or glycolate [two products of the gene DJ-1] can stop and even counteract this process, a huge step forward to finding a cure or even a way to prevent parkinson’s.
Mitochondria and Anti Aging
I’m sure you can all relate, you go to fix the sink and in the process you build a new kitchen on accident. Anyone… no? Well that is sort of what happened to researchers recently, while developing a new cancer drug, they discovered that mice lacking a specific protein live longer lives with fewer age-related illnesses. The mice, which were bred to lack the TRAP-1 protein, demonstrated less age related tissue degeneration, obesity, and spontaneous tumor formation when compared to normal mice. Pretty awesome if you think about the fact that the findings could change how scientists view the metabolic networks within cells.
Suicide, it might be in the blood
I tried to kill myself, more than once in fact. It was a troubling time for me and as a former active duty Marine that might not be too surprising for people to hear. I’m not proud of it and with where I am now, it seems like a pretty solid decision to stay alive, honestly if it wasn’t for my brothers in arms I might not even be typing this now. Unfortunately the statistic for suicide in the military is high enough that no one would have been shocked. Typically the “treatment” is therapy and medications, I say “treatment” in parentheses because you would have to know something was wrong first. But what if suicide was more than just in your head? What if it was in your blood too?
Can’t Handle the Stress? Blame your Brain
Do you rise to the occasion, or do you fold under the pressure? No matter which side of the fence you’re, you can thank [or blame] your brain. Some people can deal with stressful situations better than others, and while you might suspect it is genetic, even identical twins show differences in how they respond.
A New Hepatitis C Treatment offers Hope
Well this might seem weird, but today is world hepatitis day. I guess I should qualify weird with the fact that it’s only weird because no one really knows. What better day than to share some new news coming out of labs regarding the fight against hepatitis and what news it is! Researchers have cured 93 percent of patients with Hepatitis C in 12 weeks. Better still was well tolerated by patients. But that isn’t the only surprise so read on and find out!
Holy Grail of Battery Design: A lithium anode
Technology has been racing forward at an ever increasing rate. Unfortunately, anyone who owns a smartphone will tell you that the battery life doesn’t match the advancements. That is probably why engineers across the globe have been racing to design smaller, cheaper and more efficient rechargeable batteries to meet the power storage needs of everything from handheld gadgets to the new emerging electric cars. But a new breakthrough is about to [hopefully] change all that, a stable lithium anode.
Save the Neurons: Fighting the Effects of Parkinsons
Photo credit goes to: the The Michael J. Fox Foundation for Parkinson’s Research
Possibly one of the most famous cases of parkinson’s is Michael J. Fox. More than just the “shakes” parkinson’s can cause a whole host of other problems mentally and physically [things like lack of sleep, smell, and mood]. But now an experimental anti-inflammatory drug ,funded by the foundation with is namesake has been shown to protect vulnerable neurons and reduce motor deficits, at least in a rat model of Parkinson’s disease.
Fighting the Obesity Epidemic with X-box [No, not that one]
Despite all the efforts, people are losing the war on obesity. There is probably a number of factors involved, genetics, underlying medical problems, most of all diet, but in any case we are living in a world that is slightly heavier than our historical counterparts. Maybe that’s why so many researchers are trying to find an easy way for people to better regulate their weight. Thankfully that goal is one step closer because researchers have found a protein that controls when genes are switched on or off, one that plays a key role in specific areas of the brain to regulate metabolism.
Salmon and Spinal Cod Regeneration, er… Cord
Fish might not be the first thing you think about when we talk spinal cord injury but that is exactly what scientists are doing. Don’t ask where they got the idea, but a therapy combining salmon fibrin [a protein that acts as a scaffolding] injections into the spinal cord and injections of a gene inhibitor into the brain restored voluntary motor function impaired by spinal cord injury.
Background TV and Children don’t Mix
Coming from a, to put it gently, very broken home, my babysitter was the television. Yep, so now that you are feeling nice and awkward let’s talk television. New research, which was expanded from previous research by the same team shows that, if you are a parent, you should limit not just the television watching habits of your children but also the background television exposure.
Voyager has hit interstellar space…. maybe?
Poor Voyager, he just can’t catch a break. We’ve said it’s hit interstellar space more times than we want to admit and in 2012, the Voyager mission team announced that the Voyager 1 spacecraft had passed into interstellar space [confirmed late 2013], traveling further from Earth than any other man-made object.
When Crazy becomes a Crime
My friend has a glass eye, you would never notice and unless you knew the story you might not think anything of it. His older brother did it. Yes, you read that correctly, in a schizophrenic rage he gouged out his eye and almost killed him. He never held what happened against his older brother, he was sick, how could he? At least that was his logic. The courts didn’t agree, he would not be allowed to visit his brother while he resided in prison, even ten years [and several appeals] after the fact. Unfortunately he isn’t alone, new research has linked tighter Medicaid policies governing antipsychotic drugs with increased incarceration rates for schizophrenic individuals.
Optical Cables, from Thin Air!
It’s a project that would make Tesla proud. Just imagine being able to instantaneously run an optical cable or fiber to any point on earth, or even into space. That’s what researchers are trying to do. Did I mention it was instantaneous and involved no connection other than the air around us? Well if you are as excited as I am, then you should read on! If not, two words, laser weapons!!
Autism and Parents: Reducing stress
Raising an autistic child can be a gift. Unfortunately it can also be challenging and stressful. Let’s be real, it’s stressful just being a parent, throw in a disability that most new parents don’t understand all that well and it can be down-right depression inducing. Not because your child fall is the Autistic spectrum, but because you don’t know what that means or how to best help your child. Then it should be unsurprising that, according to a new study, peer-led interventions that target parental well-being can significantly reduce stress, depression and anxiety in mothers of children with disabilities.
Antiretrovirals and Pregnancy Risk
Don’t drink when you are pregnant, we all know that you aren’t supposed to do that. We also know you shouldn’t smoke, use drugs, and should talk to your Doctor about what medications you are taking while pregnant. So then what about when your husband is HIV positive and you want to get pregnant, are antiretrovirals safe to be using while a woman is pregnant? As it turns out, there is no real research on it, and the answer might be a little harder to get at.
HIV and Hepatitis C: A New Treatment Coming Soon!!
The old saying it could always be worse might not sound like it would apply to HIV patients. Then again if you had HIV and hepatitis C, that would probably be worse. Apparently not only it is a “thing”, but it happens often because of how both spread [blood-borne]. A multicenter team of researchers report that in a phase III clinical trial, a combination drug therapy cures chronic hepatitis C in the majority of patients co-infected with both HIV and hepatitis C.
Unraveling the Connections of the Brain
Yes it’s a brain hat, and yes I do want one!!
The brain is complex, heck if it wasn’t then we wouldn’t be smart enough to figure out how it works. I guess it’s one of those stupid catch-22 type things. Still, little is known about how the brain forms connections and the process that is behind all that. Thankfully new research provides an important glimpse into the processes that establish connections between nerve cells in the brain. These connections [also known as synapses] allow nerve cells to transmit and process information involved in thinking and moving the body. Sounds simple enough, but the formation is quite complex.
The Brain, Down Syndrome, and Antibiotics
At first glance the title might sound a little weird. But if that is the case then you probably want to read this. Researchers have identified a group of cells in the brain that they say plays an important role in the abnormal neuron development in Down syndrome. After developing a new model for studying the syndrome using patient-derived stem cells [over other models]. As the title alluded to, the scientists also found that applying an inexpensive antibiotic to the cells appears to correct many abnormalities in the interaction between the cells and developing neurons.
A New way to Fight HIV, Using your Genome!
Outsmarting something as “simple” as a virus doesn’t seem like much of a challenge. If only you could set it down to take the SAT’s or something. Unfortunately, in the body fighting HIV is more like guerrilla warfare, you take the big losses for a small win. This is no way to wage a war, but HIV is smart. It mutates and sidesteps anything we’ve been able to throw at it. We don’t have a cure, or a vaccine, but we do have scientists trying. However, new research has made a crucial jump to throwing a curveball at HIV and with it, a possible cure.
The Mediterranean Diet and Cognitive Decline
The Mediterranean diet, it may have broad health benefits [let’s face it we can’t seem to escape the push for it here in the US], but a new study suggests that it doesn’t impart the same health benefits for everyone. In fact, new research shows that its impact on cognitive decline differs among race-specific populations.
More Horror from Deepwater Horizon Oil Spill
Deepwater Horizon, it was a technological feat to get oil that deep in the water. Then the spill occurred, when it happened I honestly think more people were in shock than angry. We had never dealt with an oil spill like that before, much less one in the heart of such a huge fishing community. Louisiana business suffered and probably continues to suffer from the spill and the tons of oil that were spilled. Frankly the people in charge freaked out and just did everything they could to clean it up as quickly as possible. That unfortunately included the use of lots and lots of dispersants [chemicals to break up oil so nature can degrade and break down the oil more quickly].
Schizophrenia and Autism: A New Connection
Autism and Schizophrenia, at first glance there probably isn’t a whole lot in common other than they are disorders that fall in that lovely book the DCM-5. The brain is a complex thing, so I guess it shouldn’t be a surprise that certain forms of Autism and Schizophrenia [don’t ask me why I capitalize them, I don’t know] share a link in what at first glance seems to be an unlikely culprit.
Schizophrenic Noise and Schizophrenic Voices
Hear that voice? What, is there more than one? Is this real, or fake? How do you know? That is how schizophrenia works: auditory hallucinations, confusion, inability to tell what is real and what is not. Schizophrenia isn’t something a person can simply ignore. You can’t get rid of that voice, or even the voices on your own. But what causes this problem? That was the question researchers wanted to tackle.
New ways to test for Alzheimers
Accurately diagnosing alzheimer’s is not an easy thing to do. In fact most of the time people aren’t diagnosed until very late in the progression of the disease, long after serious damage to the brain has been done. Biological markers of Alzheimer’s disease may be able to detect it at an earlier stage. For example, using brain PET imaging in conjunction with a specialized chemical that binds to beta-amyloid protein, the buildup of the protein as plaques in the brain can be revealed years before symptoms appear. But as with anything that requires any sort of imaging techniques, these scans can be expensive and are not available everywhere. That is all about to change thanks to four new studies that aim to help offer multiple ways to test for alzheimers much earlier than we can currently test.
Infant once thought Cured of HIV tests Positive
I hate doing sad posts, it’s not my thing. But this is a big deal so I thought I would share it, the child known as the “Mississippi baby” — whom for those of you who don’t know is an infant whom had been treated directly after birth and was cured of HIV which was reported as a case study of a prolonged remission of HIV infection in The New England Journal of Medicine last fall — now has detectable levels of HIV. Even after more than two years of not taking antiretroviral therapy without evidence of virus, according to the pediatric HIV specialist and researchers involved in the case.
Antioxidants can Accelerate Cancer, ya really!
Oh rly?
Oxidative stress on the body caused by free radicals, billed as a bad thing. Fruits, veggies and just about anything with the word healthy in the title is “jam packed” with antioxidants. But they don’t provide the health benefit the are billed to have, that’s because oxidative stress isn’t a bad thing for the body in some cases. Now researchers have shown that antioxidants can accelerate cancer and we also know why.
Change your Genes with Stem Cells!
So researchers for the first time were evaluating the safety and reliability of the existing targeted gene correction technologies and in the process they successfully developed a new method of gene editing, TALEN-HDAdV [which I will explain later]. This new breakthrough could significantly increased gene-correction efficiency in human induced pluripotent stem cell [hiPSC]. You would have to guess that this is probably the science equivalent of finding a new function on your smartphone, while trying to work your microwave.
Don’t Listen to the Voices: Understanding Consciousness
There is a voice in my head. Don’t worry it’s mine… I think [a story for another time I’m sure], but why is my voice inside my head? What causes me to hear myself while I type these very words, or even better you to hear them in your voice as you read them? Consciousness is a complex and very confusing thing. I think therefore I am? Science has had trouble cracking that nut and philosophy just won’t cut it in the realm of neuroscience.
Lose Weight, Live Longer. Simple, Right?
It’s funny because it’s true.
Suprise! Really this shouldn’t come as a shock, but adults with extreme obesity have increased risks of dying at a younger age from cancer and other complications like stroke, diabetes, heart disease, and kidney and liver diseases, according to results of an analysis of data pooled from 20 large studies of people from three countries. The study found that people with class III obesity [or extreme, as defined as a BMI of greater than 40] had a dramatic reduction in life expectancy compared with people of normal weight.
Staying up late? You’re going Crazy
All night cram sessions, anyone in college has probably had more than just a few of these [okay maybe only if you are a procrastinator like me]. If you have done anything like that, well then you know how weird you start to feel. Well researchers have now shown that with a “mere” twenty-four hours of sleep deprivation can lead to conditions in healthy persons similar to the symptoms of schizophrenia. The team points out that this effect should be investigated more closely in persons who have to work at night [as anyone who works nights knows how hard that can be on a sleep schedule]. They also recommend that sleep deprivation may serve as a model system for the development of drugs to treat psychosis.
New tool helps Doctors treat Menopause
With the SCOTUS ruling for the Hobby Lobby case [if you have no idea what I am talking about you can read about that anywhere on the net, like here] it may seem like everyone is fighting the war against women’s care at full speed. Thankfully that isn’t the case everywhere, there are still people out there who are trying to make a difference. Introducing the world’s first toolkit is designed for GPs to use with women from the age of 40 to help them decide the best care for dealing with menopause. Thought to be the first of its kind, researchers say the toolkit has the potential to help manage menopausal conditions for women globally.
Breast Cancer… and Cholesterol?!
Cholesterol, it’s bad for the heart. We know LDL bad, HDL good, eat healthier or ruin your arteries. I’m sure most of us have seen the public service announcements [at least here in the states]. But if that wasn’t a good enough reason for people to watch their cholesterol then how about cancer?An association between high blood cholesterol and breast cancer has been found in a study of more than 1 million patients over a 14 year time period in the UK.
Finally! A Definite Cause of Autism: Hint it isn’t Vaccines
Autism, not caused by vaccines. In fact I’ve written several posts on the genetic clues to autism, now a new study offers more proof that it is purely genetic [at least in some cases]. This is huge because this is the first actual clear cut cause for certain types of Autism [or more accurately certain types of disorders falling under the Autistic spectrum]. It was a collaboration involving 13 institutions around the world — no easy feat either– and now researchers have broken new ground in understanding what causes autism.
“We finally got a clear cut case of an autism specific gene,” said Raphael Bernier, the lead author, and UW associate professor in the Department of Psychiatry and Behavioral Sciences and the clinical director of the Autism Center at Seattle Children’s.
Why you Should Not Fear Testosterone Therapy
Testosterone, to some it’s a bad word, bringing crazy images like “roid rage” and the like. To others with more than just a pop culture understanding it is a lifesaver. In fact, prescriptions for older men in the United States have increased more than three-fold over the past decade. Unfortunately recent studies linking testosterone use with increased risk of heart attack and stroke have caused widespread concern among patients and their families. The validity of those studies [and their methods] have been in question and [yet another] new study aims to help end the confusion. The new U.S.-based study of more than 25,000 older men shows that testosterone therapy does not increase men’s risk for heart attack.
The study examined 25,420 Medicare beneficiaries 66 years or older treated with testosterone for up to eight years. Studies like this one are tough to do so the researchers used public health data to wade through the claims.
Saving the Rainforest and the Consequences
The road to hell is paved with good intentions. This seems even more true when a new study came out that shows, when it comes to fixing deforestation and forest degradation, even good intentions can lead to bad outcomes. I hate to sound like a broken record when it comes to this whole “climate change” stuff, but it really needs to be addressed sometime…
St. Johns Wort and the Dangers of “Alternative” Medicine
Grapefruit juice, I hate the stuff. But did you know that if you drink as little as 8 oz. of it when you take certain medications it could dramatically increase the effectiveness of the medicine? Sounds like a great thing, sure, until you realize that the dose of medication you are taking is specific to you and that increasing it can have serious side effects and in some cases cause death. This discovery led to the inclusion on the labels of certain medications to be cautions about grapefruit juice [and grapefruit] consumption.
Noninvasive Brain Control via Jaws!
Mind control, we’ve seen several semi [see very] invasive ways to make it happen here from the Labs. Now those crazy scientists from MIT have developed a technique that allows researchers to enable neurons to be silenced noninvasively, using a light source outside the skull. All using a protein known as Jaws.
Optogenetics [a technology that allows scientists to control brain activity by shining light on neurons] uses light-sensitive proteins that can suppress or stimulate electrical signals within cells. This technique is very invasive though because it requires a light source to be implanted in the brain, where it can reach the cells to be controlled.
A Startling New Climate Change Revelation!
Call out the troops, call the Marines, we need tanks, lots of tanks. Well okay, maybe not. Brute force won’t stop global warming and thanks to a new study on the subject it turns out, not much else will either. Oh there is of course the obvious lower CO2 emissions, but that’s not a big deal. I don’t know why it takes scientific studies to tell us this, but the greenhouse gas CO2 that we pump out in millions of tons — roughly 88 million tons, US of course since metric tonnes has to be different, or maybe that’s our fault — is bad for the environment.
I know we tend to think of ourselves as intelligent and generally I won’t argue otherwise, but let me just say… really?
Tofu and Solar Cells: An unlikely pairing
Solar cells, they’re kind of a big deal. Good for the environment, produce power from that big ball of burning gas we call our sun, they like long walks on the beach, cool drinks and just chilling with friends… oh sorry that’s from the wife swap [the wife and I love that show]. But in all seriousness, solar is the next oil. We had an industrial revolution and now we are going to have a more eco-friendly kind of revolution. Of course the high price of solar panels has made it all but inaccessible to the general public [I know I would love to have some on my roof!]. With natural gas and other sources of power being cheaper, solar needs to learn a few new tricks to keep up. Thankfully that is exactly what scientists at the University of Liverpool have accomplished.
Right now solar cells are inefficient at about 15% of the power actually converted to usable electricity. It is unfortunate then that solar cells need to be coated in a cadmium chloride to reach that paltry efficiency. I’ll let you in on a little secret, if it wasn’t for that coating we would only see about a 2% power conversion. Yeah damned if you do damned if you don’t stuff. That’s because that coating is roughly $0.30 a gram, doesn’t sound like much, but it adds up quick. Not to mention that there is a little problem with it being very toxic, incredibly hard to handle safely and hard to dispose of after solar cell decommission [I know… details, details].
Finally, a Better Battery!
That’s the million dollar question.
You know what technology hasn’t been able to keep pace with us? Well besides whatever tech the DMV uses, it’s batteries. Think about it, they are nasty, make a mess, are hazzardous, hard to recycle and weigh a freaking ton compared to the energy stored. Current battery technology is my number one problem with electric cars as it stands now. Between the weight, the resources, and the waste, electric cars are almost a wash. Not quite mind you, but almost.
That’s about to change, maybe not for the electric car, but for the energy grid. Right now power is pumped out as fast as it’s being used. There is no real storage anywhere for surplus power so it is made on demand for people to use it as it’s being produced. This use as you make it system has proven to be the bane of solar and wind, the two major renewable energy technologies we have. This problem combined with the lobbyists for oil and gas companies and you can see why we don’t have more solar or wind power plants.
Anti-aging drug has a Catch… but not for Long
Dietary restriction holds the key to longevity. It’s no secret that as you drastically reduce calories, your metabolism will slow down with it [ask anyone who’s tried to crash diet about that one]. Science has been trying to crack that egg for awhile now and because of that, it is the most researched method for slowing down the aging process. That was why researchers were so excited to find that a drug — rapamycin — appears to mimic that anti-aging effect.
Rapamycin, an antibiotic and immunosuppressant approved for medical use about 15 years ago, has drawn extensive interest for its apparent ability — at least in laboratory animal tests — to emulate the ability of dietary restriction in helping animals to live both longer and healthier. If the name sounds familiar that is because rapamycin is primarily used as an immunosuppressant — to help prevent rejection — specifically for people who have had organ transplants.
Autism and Pesticides: What, too obvious?
There have been a few different things linked to children who fall under the Autism Spectrum Disorder. A combination of genetic and environmental factors, along with complications during pregnancy have been associated with the diagnoses. And a new study aims to strengthen the link between prenatal exposure to pesticides and autism [Please hold your collective duh’s until the end]. The large, multi-site California-based study examined associations between specific classes of pesticides, including organophosphates, pyrethroids and carbamates, applied during the study participants’ pregnancies and later diagnoses of autism and developmental delay in their offspring.
To Lose the Weight, Feel the… freezer burn?
Are you so fat you can’t see your toes? Have you forgotten what toes even look like? Have you been mistaken for the infamous “Kool-aid man”? Want to shed the pounds easier than taking off your shirt? Well too bad, that is science fiction and the stuff of horrid marketing ploys and this my friends is a science website. Losing weight is hard, I’ve written several articles on it in fact. Nothing is going to be more effective at weight loss than a sensible diet, a calorie deficit and maybe some insoluble fiber that I mentioned in the very first article I’ve written.
A new companion study to this post, which I wrote not long ago not only confirms that original studies findings, but also gives insight into another factor for the mounting obesity epidemic.
The Love Song of Philo T. Farnsworth
Photo from Brian and Bill’s Plasma Pursuits Blog
Philo Farnsworth, if the name sounds vaguely familiar than you might just be a Futurama watcher. If you don’t watch and know who I’m talking about or even better are a fan then, “YAY!” and for those of you who don’t know, don’t sweat it you’re not alone. One of the forgotten greats, Farnsworth should be a household name, namely because one of his biggest inventions is in practically every home.
Did you guess it yet? If you said Television, then you are correct!! [If you didn’t, but wish you had, then good enough!] Philo Farnsworth wasn’t necessarily a genius, he didn’t escape the holocaust like Einstein, nor did he make millions from his inventions like you might expect. In fact, Farnsworth lead– by all accounts — a fairly unassuming life. Interesting when find out that not only did he invent the modern television, but he did it at the ripe old age of 14 years old. No, not 41 that wasn’t a mistype, he was 14 years old.
Global Warming doesn’t actually benefit Plants
Things are heating up. It’s no secret that the mercury is rising and we are to blame. Sure, there is a lot of uncertainty, for example how long we have until we simply cannot reverse global warming, or worse, how long we have before we cannot survive on the planet. That would be a good question to answer; maybe it will get the people who can actually do something to fix it, to make a change.
The planet works in sometimes-unforeseen ways, sometimes that is good and sometimes that is bad. The hope was that global warming might be offset – if only for a short time – by the increased energy in the system [meaning longer warm periods], which would increase the growing season. It is unfortunate then, that this turns out not to be the case.
Lunatic Laboratories
