As our cells age, they eventually mature and die. As they die, they alert nearby cells to grow and multiply to replace them. Using a special imaging process that combines video and microscopy, scientists have observed the cellular communication between dying and neighboring cells for the first time, and think they may be able to use their new-found information against cancer cells, whose damaged genomes let them escape the normal dying process.
Even though HIV rates declined 18% between 2008 and 2014, 1.1 million people in the US are living with the infection. Part of that is because HIV is treatable, but not curable.
Type 1 diabetes is an attack on the body by the immune system — the body produces antibodies that attack insulin-secreting cells in the pancreas. Doctors often diagnose this type of diabetes in childhood and early adulthood. The trigger that causes the body to attack itself has been elusive; but many research studies have suggested viruses could be the root. The latest links that viruses that live in our intestines may yield clues as to which children might develop type 1 diabetes.
Natural remedies used through the ages abound, especially in Asian medicine. The willow-leaved justicia plant, found throughout Southeast Asia, has traditionally been used to treat arthritis, but scientists have just discovered it contains an anti-HIVcompound more potent than AZT. AZT was the first drug approved to treat HIV, and is still used in HIV combination therapy today.
A promising new antibiotic has been discovered in, of all things, another bacteria. Burkholderia bacteria live in diverse habitats, including soil, plants, and humans where they thrive by knocking out other microbes that compete with them for resources or threaten their existence. Scientists have discovered they accomplish this by producing a very effective antibiotic.
New research reveals how E. coli bacteria construct elaborate and effective tunnels to pump unwanted molecules like antibiotics and other toxins out of cells. The discovery could help us better understand how antibiotic resistance occurs and give us a leg-up to beat them at their own game.
A new medical development is going to change the way many of us look at getting the flu vaccine. A painless flu vaccine skin patch is making needles and vials a thing of the past. Researchers from the Georgia Institute of Technology and Emory University have shown that a flu vaccine can be administered safely and comfortably with this new patch, which delivers the vaccine through a matrix of tiny dissolving microneedles.
Look no further than Flint, Michigan, to discover the serious consequences of contaminated drinking water. Around the world, water polluted by pathogens and toxins sickens people or cuts them off from safe drinking water. Looking for a solution, researchers created tiny, swimming robots that pack a powerful punch against waterborne pathogens.
About a third of the methane released into the environment comes from the production and transport of natural gas. The gas leaks as it moves along the transport chain from gas wellheads to market.
With a death rate of one in five, sepsis is a fast-moving medical nightmare. New testing methods might improve your odds of survival if this infection ever hits you.
News: Bacteria Turned into Factories, Supplying Critical Enzymes to Make Cancer Drugs Cheaper & Save Endangered Yew Trees
Cytochrome P450 (P450s) are proteins found in nearly all living organisms, which play roles that range from producing essential compounds and hormones to metabolizing drugs and toxins. We use some of the compounds synthesized by P450 in plants as medical treatments, but the slow growth and limited supply of these plants have put the drugs' availability in jeopardy and jacked up prices.
News: Vaccine Can Prevent Bad Cholesterol from Accumulating in Blood Vessels, Potentially Prevent Heart Attacks
Heart disease is the leading cause of death of men and women in the US. Over half a million Americans die from it annually. Atherosclerosis — a build up of plaque in the arteries — is a common feature of heart disease and can be caused by smoking, fats and cholesterol in the blood, diabetes, and high blood pressure.
Colorectal cancer — cancer of the colon or rectum — is the third most commonly diagnosed cancer in the US. To reduce the chances of a diagnosis we are all urged to stop smoking, keep our weight down, decrease our intake of alcohol and red meat, keep active, and get screened for colon cancer. But, new research has found something that participates in the development of colorectal cancer that might not be as easy to control: A strep bacteria that promotes tumor growth.
Coronaviruses are common viruses, and most of us catch one at some point — they cause about 30% of all common colds. A new accidental discovery could help fight these viruses, even the deadlier, emerging ones.
News: Defective Sugar-Loving White Blood Cells Could Be Why Cardiac Patients Get More Viruses, Like Shingles
People who have heart disease get shingles more often than others, and the reason has eluded scientists since they first discovered the link. A new study has found a connection, and it lies in a defective white cell with a sweet tooth.
What would it be like to have clothing that killed microbes? Or paper that repelled pathogens? A research team from Rutgers University has developed a prototype out of metalized paper to zap the bad guys without being super expensive. Sound good? Read on.
Bone loss and belly fat may no longer be certain fates of menopause, thanks to new research from an international team of scientists.
News: New Approach Could Be Silver Bullet Against Antibiotic Resistant E. Coli & Other Gram-Negative Bacteria
Some types of bacterial infections are notoriously tough to treat — and it's not all due to antibiotic resistance. The bacteria themselves are rugged and hard to penetrate with drugs.
If the all the fingerlike projections in our gut were flattened out, its surface area would be 100 times bigger than our skin's. It's so large that the actions of just a small part of it can impact our health. A new research study has found that enterochromaffin cells in the intestinal lining alert the nervous system to signs of trouble in the gut — trouble that ranges from bacterial products to inflammatory food molecules.
Respiratory Syncytial Virus (RSV) is the most commonly occurring lower respiratory tract viral infection in young children and usually isn't serious, but in premature infants and babies under six months old, the infection can be severe, and even fatal.
