How you get Ingrown Toenails, explained by Science

ingrown_toenail

Having a ingrown toenail could ruin your day and a lot after if you don’t have it fixed. Yet, even though ingrown nails and other nail-related conditions are common and pesky, very little is known about them. Now, a team at University of Nottingham have published a mathematical model that explains what forces are tugged beneath your finger nails and what exactly happens when…

The 1918 Spanish flu killed between 50 and 100 million people. This man is recreating it in a lab

h5n1-virus-01-1014-mdn

Yoshihiro Kawaoka has caused massive uproar in the scientific community when he announced he is attempting to recreate the world’s most lethal virus. Biologists are polarized on the issue, with some claiming that it is reckless, while others approving that it will help us better understand pandemics and how we can protect ourselves against them. Kawaoka is a veterinary researcher….

Cancer may be an Ancient ‘Safe Mode’ Mechanism that Evolved to Protect Us

cancer

An innovative research posits that cancer may actually be a sort of ‘safe mode’ mechanism, akin to how a computer’s operating system reverts back to safe settings to preserve itself, which evolved shortly following the first single celled organisms. The research was made by an unlikely team of scientists: an oncologist, an astrobiologist and a cosmologist. If the findings are right, then cancer may be fought off more effectively using oxygen treatments and infection with viral or bacterial agents….

Heart rate variability keeps the body in optimal shape

heartrate

The heart regularly speeds up or down its beating frequency to adjust to the body’s needs. Even in stable conditions (when you’re not particularly active or your active for a constant time), the amount of time between heart beats is variable. A team of doctors and engineers at Caltech’s Division of Engineering and Applied Science have now found a better way to assess…

Children needlessly prescribed antibiotics at an alarming rate

In many cases, doctors prescribe antibiotics to children, but most of the time, those viruses don’t even respond to antibiotics, a study finds. When you have a cold, or a headache, there’s a good chance you might just shrug it off, or fight it with an aspirin or some Tylenol – but if your child is suffering, the odds are you…

Sofosbuvir is a very effective drug against Hepatitis C, effectively curing the disease in over 90 percent of all cases. Sofosbuvir is a component of the first all-oral, interferon-free regimen approved for treating chronic hepatitis C.Interferon-free therapy for treatment of hepatitis C reduces the side effects associated with use of interferon. However, a 24 week treatment in the US costs $84,000 –…

Ebola vaccine trial begins

The vaccine will start human trials sooner than planned due to the urgency of the outbreak. Image via BBC.

We might be dealing with the worst Ebola outbreak in history – even though no one would have predicted this a few years ago. Hastened by the urgency of the matter, a trial of an experimental vaccine against the Ebola virus is to begin in Oxford. Normally, it would take another couple of years of testing before such a vaccine would…

Skin-penetrating ionic liquids mixed with antibiotics provide better way of killing microbes

Staphylococcus_aureus_biofilm_01

As microbes become more and more resistant to antibiotics and cleaning products, it’s crucial that we find better, more efficient way of fending them off. Dr. Samir Mitragotri from the University of California at Santa Barbara has led a team which showed that ionic liquids (ILs), also known as liquid salts, dramatically improve the treatment of microbial biofilm skin infections, while also…

The origin of fever: study shows it stems from the brain

Researchers have described the mechanism of formation for a key substance that triggers fever. Image: Flickr

Occasionally we’re hit by fever. Nobody likes it, most sane people actually hate it, but it’s important to note that it’s an important part of the healing process. Fever is a result of the immune response by your body to foreign invaders like viruses, bacteria, fungi, drugs, or other toxins. Research showed that it is triggered by an onset of the…
