This year the world saw the worst Ebola outbreak on record with more reported cases than in all the past years combined. Much more. The latest update from the Center for Disease Control and Prevention reports 9,178 patients, of which 4546 have died. The actual number of people infected with Ebola is actually much larger, in part because the report…

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…

Regeneration of the spinal chord following a paralyzing injury was thought to be impossible, but groundbreaking efforts stirred by surgeons in Poland and Britain have turned this paradigm upside down. A team of dedicated surgeons and scientists transplanted  cells from the nasal cavity of a patient who had been paralyzed from the waist down for more than two years into…

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….

A Rogue gone Good: Mitochondria was initially an Energy Parasite

Image: knowingneurons.com

A new milestone study found that mitochondria – the energy factories in animal and plant cells – were initially very similar to parasitic bacteria some two billion years ago, and only later did they become energy sources. Very little is known about the origins of mitochondria, but by probing the genomes of bacteria closely related to the energy cell scientists at University…

Computer Simulation shows How Bacteria Resist Antibiotics

Researchers at the University of Bristol used a complex computer simulation to determine how enzymes in bacteria breakdown antibiotics, rendering them useless. The same simulation could be used to see how certain drugs respond to various bacteria, predicting their resistance and efficacy. This way, doctors will be able to prescribe the best antibiotics for a particular outbreak, saving time, energy,…

We all know the bond between dogs and humans is very powerful and meaningful – but a group of researchers took it to the next level. They wanted to see how this relationship actually mirrors the one between a parent and a child. The researchers, from Massachusetts General Hospital, have detailed their findings in the journal PLOS ONE. “Pets hold a special place in…

It’s common knowledge that babies born out of tall parents will most likely grow to be just as tall, but it’s only recently that scientists report finding most of the genes responsible for height. Information like this could prove to be useful in diagnosing genetic growth deficiencies or, in the not so distant future, genetic manipulation to enhance growth in height. Short…

Whether we’re assigned a learning task or choose to follow it, those subjects that interest us are always easier to comprehend, assimilate and remember over a long time. In this context, interest is actually another word for curiosity and a new research found that it is an important factor for effective learning. The team at University of California, Davis, found that…
