Ever since the first cells evolved about 3.8 billion years ago, they have had to contend with other life forms intent on killing them. Today, wherever cells exist, viruses exist. It is likely this relationship goes back to time immemorial. Meet the eukaryotes that suck.

With the recent discovery of polymyxin-resistant infection here in the U.S., there's a renewed pledge among drug developers and the government to incentivize research for developing new antibiotics, previously a seemingly abandoned effort.

New York City Mayor Bill de Blasio really hates salt. But, we suspect it goes deeper than this. He may be a "condiment bigot." Possibly even a mustard hater, or an anti-mustite.

Ketamine is an anesthetic that can prevent persistent post-surgical pain in patients who have undergone major surgery. That's a welcome alternative, given the significant opiate addiction crisis plaguing our nation.

It didn't take long to guess what might be going on: We're educating a whole lot of people about the differences between health scares and health threats -- and doing it well.

Naturopaths have been and continue to push for federal reimbursements for their treatments and they often consider themselves as professional equivalents of actual physicians who have studied actual medicine. The "profession" should be considered what it is - a hobby.

Poo offers a wide spectrum of opportunities for assessing animal health, according to guest writer Katherine Whitehouse-Tedd, who is a visiting fellow for Animal & Equine Science at Nottingham Trent University.

Urine tests that can signal dehydration in young adults or children may not be so accurate in the over-65 group. The possible reasons are numerous — ranging from impaired kidney function to medications that affect urine color.

In hopes of tackling Thailand's obesity problem (Thai food is especially yummy and greasy), some creative minds have designed a plate that literally sucks the excess fat and calories from a meal.

The Department of Defense has revealed that a woman in Pennsylvania was detected carrying a strain of E. coli with 15 different genes conferring antibiotic resistance.

The Food and Drug Administration has announced that it has approved Probuphine, an implant for treatment of opioid dependence. It's designed to provide a constant, low-level dose of buprenorphine to patients for six months.

The tobacco industry just got buzzed with a high-and-tight fastball, a knockdown pitch if you will. And if it chooses to stand up and go to court to fight the legal charges being hurled by the family of Tony Gwynn, the late Hall-of-Fame major leaguer, don't be surprised if one tobacco maker goes down swinging -- even if it has science on its side.

Yale researchers have discovered a virus that attacks bacteria, also known as bacteriophage (or "phage"), which is capable of infecting Pseudomonas aeruginosa, a highly-feared bacterial pathogen.

The FDA is finally advising the food industry to stop using the euphemism "evaporated cane juice" for sugar on food labels. Ingredients on food labels should be couched in terms that the average person is familiar with. It's just too bad the advisory isn't binding.

The TV show "The Biggest Loser" may provide entertainment, but it does so at the expense of the contestants. ACSH advisor Dr. David Seres explains why, while delivering this message: Stop telling the obese to lose weight.

Microbiologists don't use microscopes very often. The reason is because a substantial proportion of modern microbiology research uses the tools of molecular biology, for which microscopes are not needed.

A published report in Occupational and Environmental Medicine deceptively concludes a positive association exists between exposure to ambient air pollution and increased risk of stillbirths.

Memorial Day weekend is a time, first and foremost, to remember and honor our country's fallen military heroes. It is, unofficially, a time to get outside, celebrate that summer is coming, and fire up the grill. Before you start marinating the meat though, a new study brings attention to a hidden danger associated with grilling - the wire-bristle brushes used to clean them. When bristles get loose on these brushes, they can fall out, stick to the grill, be transferred to food and ingested.

In approximately one-third of patients diagnosed with pancreatic cancer with locally invasive tumors but without metastases, surgical removal of the tumor conferred significant survival benefit if done in conjunction with pre-operative chemotherapy and radiation.

Obese children and adolescents are at risk of becoming obese adults — with many associated health issues. Thus a school-based intervention program that delivered promising reductions in obesity prevalence among middle school students deserved further attention and replication.

Almost every week there is another scientific/medical advance made using the CRISPR-Cas9 system. Of course, we will continue to bring you news about all of the great ways in which CRISPR-Cas9 can be used in the future. But before we talk about medical advances, we first need to understand how the CRISPR-Cas9 system works.

Former New York Times columnist Mark Bittman enthusiastically endorses a tax on soda and other sweetened beverages that's now being considered in Philadelphia. While this may seem appealing to people who believe that sugar is a major contributor to America's health problems, when you really examine the logic of such a tax, there isn't much there.

Researchers have found that ketamine, when used as an alternative to haloperidol for sedating combative patients, yielded quicker onset to sedation time, but with more adverse side effects.

The language of science has been hijacked. Those who are looking to make a quick buck (or in the case of the organic industry, 43 billion bucks) have no qualms about twisting the definition of highly precise scientific terminology to suit their own profit-driven agendas. Here's a brief glossary of the some of the most commonly misused scientific terms. (Note: the health food and fad diet industries are among the biggest abusers.)
