Paracetamol is the most common painkiller which we all rely on to treat our aches and pains, but it turns out that you might also be  decreasing your empathy for both the physical and social pains that other people experience, a new study conducted at Ohio State University suggests.  It turns out that paracetamol may not only be a painkiller but also an emotion-killer. Researchers found that, for example, when participants in the study took paracetamol and were informed of the misfortunes of others  they thought these individuals experienced less pain and suffering,when compared to those who took no painkiller. "These findings suggest other people's pain doesn't seem as big of a deal to you when you've taken acetaminophen," said Dominik Mischkowski, co-author of the study and a former Ph.D. student at Ohio State, now at the National Institutes of Health. "Acetaminophen can reduce empathy as well as serve as a painkiller." This research

We can buy common painkillers over-the-counter at  a pharmacy or even be prescribed them in copious amounts for the treatment  of difficult conditions such as colds, flu, pain, inflammation, and fever. However, all drugs come with side effects, such as increased blood pressure or an increased risk of ulcers. A new study has gathered all the information on each side effect of each common painkiller and its effect on patients with different health conditions (such as diabetes or heart-related diseases). What you need to know about NSAIDs: NSAIDs is an abbreviation for Nonsteroidal Anti-Inflammatory Drugs and is used to treat a wide range of diseases, in particular, disorders in the muscular and bone system, where the drug counteracts swelling, pain and limitations in movement associated with inflammation. NSAIDs are not antibiotics and therefore do not help to fight infections caused by bacteria. NSAIDs are in Denmark sold both in low doses (Ibuprofen 200 mg/tablet) withou

HIV is a virus that attacks the immune system and weakens your ability to fight incoming infections and diseases. The Human Immunodeficiency Virus currently has no cure but there are currently treatments which are able to help people with the virus to live a prolonged, healthy life.  Since there is no cure for HIV, the best way to approach preventing the spread of the virus is by vaccination; enabling the body to fight off the virus before it attacks the immune system.  Researchers in the USA have been working on developing a vaccine capable of inducing "broadly neutralizing" antibodies that can prevent HIV infections.  This new vaccine technique aims to immunize people with a series of different engineered HIV proteins as immunogens to "teach" the immune system to produce broadly neutralizing antibodies against HIV. This in turn, will prepare the immune system to fight off an incoming virus which carries similar proteins to the HIV proteins. The group of

First of all sorry that I have been M.I.A recently. It's been just over a month since I've last posted a science blog on here. Click here to see my latest blog post- :) Within the last month, I came down with the cold, gotten better then suddenly relapsing into another cold, which was 10 times worse than the previous one (imagine coughing continuously - ALL DAY!). Thankfully, I am feeling better now and I am trying to get back into my usual routine. So starting this week expect more regular posting from me! The funny thing is I have a post on how to prevent cold and flu - and I couldn't prevent it from myself! #NeedMoreImmunity #VitaminC The science of a "relapsing cold" Actually, a cold cannot relapse, you've most likely caught another cold virus (unlucky, I know). F.Y.I  a cold/flu is a virus, not a bacteria, so you won't and cannot be prescribed antibiotics for it.  This awesome video by ASAP science goes through the different type

For any medical reason, sometimes artificial organs are required to take place instead of the real organ in the human body. But making artificial organs, which have complicated and  intricate structures, aren't easy to make and there have been many methods which have been devised but don't work as efficiently.  Leon Bellan is an assistant professor of mechanical engineering at Vanderbilt University, who has been working with candy floss machines, getting them to spin out networks of tiny threads similar in size, density and complexity to the patterns formed by capillaries - the minuscule, thin-walled vessels that deliver oxygen and nutrients to cells and carry away waste. His main aim has been to make fibre networks that can be used as templates to produce the capillary systems required to create full-scale artificial organs. This research has been published in the Advanced Healthcare Materials  journal. Bellan and his colleagues have been successful in using their

A new report featuring in the February 2016 issue of  The FASEB Journal , scientists show that a gene called "DISC1," is believed to play a role in mental health disorders, such as schizophrenia, bipolar disorder (and other forms of depression); influence the function of pancreatic beta cells which produce insulin to maintain normal blood glucose levels. Understanding how the different mechanisms  of diseases in the body is essential to be able to pick efficient therapies for patients. Bortell and colleagues decided to study the function of DISC1 by comparing 2 groups of mice. The first group was genetically manipulated to disrupt the DISC1 gene only in the mouse's pancreatic beta cells. The second group of mice was normal. The mice with disrupted DISC1 gene showed increased beta cell death, less insulin secretion and impaired glucose regulation while control mice were normal. The researchers found that DISC1 works by controlling the activity of a specific protein (GS

W e haven't quite forgotten the ebola virus and a new virus has appeared under the spotlight; the Zika virus. The Zika virus is spread by mosquitos, similar in a way to malaria. However, unlike other mosquito-borne diseases, it is relatively unknown and little studied. The virus is currently showing an alarming rise in cases in Latin America and the Caribbean.  The virus has also  been associated with an alarming rise in babies born in Brazil with abnormally small heads and brain defects -- a condition called microcephaly.  Zika is spread by the same mosquito as the dengue virus: Aedes aegypti. Dengue is a serious disease but it doesn't usually kill people, whereas, Zika, is much more serious in that it is able to pass through a woman's placenta and impact the unborn child.  Since the Zika outbreak began in northeastern Brazil last spring, an estimated 500,000 to 1.5 million people have been infected. The resulting illness only lasts a few days. The symptoms consist

This blog post was previously titled: Females are less prone to influenza than males, thanks to Estrogen.  E strogen and its derivatives have been found to protect against respiratory infections such as influenza, in females more than males. This new study was published in the American Journal of Physiology-- Lung Cellular and Physiology. A virus usually works/makes you ill by invading a cell in your body and making and replicating itself within the host cell. After being released from the host cell, the virus can go on to infect other cells in the body and also other people.   The less a virus replicates, the less severe the infection and the lower the risk it will be spread onto other people. The researchers used human nasal epithelial cells (hNECs) from male and female donors- which are the main cells which the flu virus targets - and exposed the nasal cells to  17β-estradiol   (i.e estrogen) or select estrogen modulators (SERMs) (these include natural and synthetic comp

Dan Perlman, a biophysicist, and K.C Hayes, a nutritionist,  have previously  developed the "healthy fats" blend in the Smart Balance buttery spread over twenty years ago; have now invented the parbaked coffee bean. This new method of roasting green coffee beans is meant to enhance the health benefits of coffee. Perlman developed the flour milled from parbaked beans to act as both a food ingredient and a nutritional supplement.  Many studies have proven that drinking coffee is good for you and I've written several posts on coffee in the past  here , here , here and here :) Perlman wanted to study a way to roast coffee beans but at the same time not loose its health benefits. When coffee beans are roasted at over  400 degrees Fahrenheit for 10 to 15 minutes -- the CGA content drops dramatically. One study found the decrease ranged from 50 to nearly 100 percent. Chlorogenic acid (CGA)is an antioxidant. CGA is thought to be beneficial in controlling sugar me

The elements 113, 115, 117 and 118 have finally been discovered.   Laboratories in Russia, the United States and Japan have made many claims over the  years  that they have discovered them. But it was only at the end of 2015 when the elements were finally given their  permanent  place in the periodic table. A group of scientific experts at  The International Union of Pure and Applied Chemistry (IUPAC), headquartered in Research Triangle Park, North Carolina,  announced the group’s conclusions  on 30 December 2015. The four elements were made in the lab, by colliding  lighter atomic nuclei together. The unstable agglomerations of protons and neutrons lasted mere fractions of a second before they fell apart into smaller, more stable fragments. Each of the teams have been given recognition for their great findings which means that now, they can  put forward proposals  to name the new elements and assign them their two-letter symbols. A new element can be named after a range of th

Today's final post in the series will be on the science behind Santa's sleigh. Scientists at the North Carolina State University have analyzed and researched how Santa is using the latest scientific resources and technologies on his sleigh (that aren't scientifically available to us yet) to deliver everyone's Christmas presents. To deliver all the presents on time Santa's sleigh has to be a million times more advanced than any modern form of air transportation . The truss of the sleigh, including the runners, are made of a honeycombed titanium alloy that is very lightweight and 10 to 20 times stronger than anything that exists or that's being worked on in labs today. But it  doesn't  just stop there....  The truss can also morph, changing its shape slightly to improve its aerodynamics – allowing it to cut through the air more efficiently. The runners on the sleigh, for example, are a little bit flexible; this allows the runners to be tucked in

It's the day before Christmas eve, so Christmas preparations are well under way. Who will be making homemade eggnog this holiday season? And will you be "spiking" it? If you will, beware of the risk of salmonella in raw eggs.  With a statistic of 1/20000 eggs is contaminated with salmonella bacteria drinking homemade eggnog can be a bit of a hefty risk. Scientists at Rockefeller University conducted an experiment on eggnog and spiked eggnog (with alcohol added to it =  20 percent rum and bourbon) to compare the  bacteria found in homemade alcoholic eggnog with those found in store-bought nonalcoholic eggnog. After culturing samples of both solutions and incubating them for 24 hours at 37 degrees Celsius (body temperature), The researchers found that while the store-bought product was brimming with a variety of bacteria, the homemade version was completely sterile. “The bacteria we observed in the grocery-store product are likely harmless normal bacteria that

Today's post is based around candy canes - but not candy canes exactly, more like Christmas sweets including licorice. Scientists have found that a novel molecule extracted from licorice root has the ability to stop some cancers immediately, according to a collaborative research study conducted at Rutgers, The State University of New Jersey.  Mohamed Rafi, assistant professor in the department of food science at Rutgers' Cook College, discovered the new molecule, ß-hydroxy-DHP (BHP), in common dietary supplements made from licorice root, a natural remedy with curative powers which have gone down in history. Rafi tested the compound in the laboratory on tissues taken from prostate and breast cancer tumors. The small and very specific molecule BHP  belongs to a class of organic chemicals known as polyphenols that include potential anticancer compounds found in green tea and wine; its main target is cancer cells. It works by deactivating a protein associated with t

Today's post will be on walnuts. Walnuts also constitute a part of the Christmas platter and they're also good for you. Most of the health benefits of walnuts are known already but scientists have found one more to add to the list: lowering of diabetes and heart disease risk in "at-risk" patients.  The research was published in the  Journal of the American College of Nutrition , the Official Publication of the American College of Nutrition, and a publication from Routledge. For the study, a sample of 46 adults aged 30-75 were selected. Participants had a Body Mass Index larger than 25, and a waist circumference exceeding 40 inches for men and 35 inches for women. They were also required to be non-smokers, and all exhibited one or more additional risk factors for metabolic syndrome, a precursor of diabetes and cardiovascular disease. The group was randomly assigned to two 8-week sequences of either a walnut-enriched ad libitum diet or an ad libitum diet

Every year baubles get more innovative from your typical gold and sliver baubles to solar system themed baubles and finally gold and silver nano-baubles. The nano-baubles produced by researchers, in Mexico and the US, are about 100 million times smaller than the typical baubles which are used to decorate Christmas trees. The research was published December 2010 i ssue of the  International Journal of Nanoparticles , where the  scientists  reported the formation of various sliver, gold and bimetallic nanoparticles which are only 25 nanometres in diameter.  They  utilized  vitamin C (a.k.a ascorbic acid) and a soap like antiseptic which is usually used in high-end cosmetics. The reaction of silver nitrate and the  gold compound chloroauric acid under these conditions led to successive reduction of the metals and the formation of different silver, gold and bimetallic nanoparticles. The precise structures of the nanoparticles were revealed using a high-resolution elemental mapp
