When a clear sunny day turns into clouds, people used it to explain their grave mood without taking into consideration how clouds can affect global warming in the atmosphere. But University of Georgia marine researchers have discovered the process of an anti-greenhouse gas known as DMSP (dimethy... Read More
I listened to the latest TWIP this morning. Dickson mentioned the herbicide atrazine but thought it was a fungicide. It is actually a herbicide in the photosynthesis inhibitor class. Another bit of trivia about ag chemicals is that old chemicals like ... Read More
Influenza viruses evolve rapidly, making it hard to develop protective vaccines against them. Despite a great deal of effort, scientists have found it difficult to forecast which way the virus’ evolution would take it. Now, thanks to improvements in our ability to study viruses and a new mathema... Read More
The bacterium Staphylococcus Aureus (S. aureus) is a common source of infections that occur after surgeries involving prosthetic joints and artificial heart valves. The grape-shaped microorganism adheres to medical equipment, and if it gets inside the body, it can cause a serious and even life-t... Read More
Doctors have used gene therapy to upgrade the immune system of 12 patients with HIV to help shield them from the virus's onslaught. It raises the prospect of patients no longer needing to take daily medication to control their infection. The patients' white blood cells were taken out of the body... Read More
A new device from Macquarie University can manipulate objects as small as 50 nanometers wide — about a thousandth of the width of a human hair and small enough to allow direct manipulation of a single viral capsule.

Scientists have known for years that together, bacteria and plants can remediate contaminated sites. Ramakrishna Wusirika, of Michigan Technological University, has determined that how you add bacteria to the mix can make a big difference. Wusirika has also shed light on the biochemical pathways...

Researchers have debated for more than two decades the likely impacts, if any, of global warming on the worldwide incidence of malaria, a mosquito-borne disease that infects more than 300 million people each year. University of Michigan ecologists and their colleagues are reporting the first har... Read More
If a sexually active woman wants to protect herself from unwanted pregnancy and HIV using a single method, she has always been limited to condoms. A new paper, released today in PLOS ONE details a first-of-its-kind device that provides an alternative.

Beer drinkers know that hops are what gives the drink its bitterness and aroma. Recently, scientists reported that the part of hops that isn’t used for making beer contains healthful antioxidants and could be used to battle cavities and gum disease. In a new study in ACS’ Journal of Agricultural... Read More
Washington University in St Louis chemist Timothy Wencewicz says we’ll stay ahead of antibiotic resistance only if we find drugs with new scaffolds, or core chemical structures. One promising candidate, an antibiotic made by a bacterium than infects plants, caught his attention because it contai... Read More
Doctors are reporting a second instance of a baby born with AIDS going into remission, or possibly cured, by aggressive treatment after birth. The first case, a child from Mississippi who is now 3 1/2, was reported last April. Doctors revealed the case Wednesday at an AIDS conference in Boston. ... Read More
While genetics likely play a role in some instances of colorectal cancer, a new study in mice suggests gut bacteria could also influence development of intestinal tumors. Researchers from the Icahn School of Medicine at Mount Sinai found that giving antibiotics to mice to disrupt their microbial... Read More
For reasons that still aren't well understood, bacteria proliferate in microgravity. Creating a potential recipe for disaster for humans stationed in space for long periods, bacteria's love of low-g also raises an intriguing question: Why are they so comfortable there?

One way to avoid getting sick while traveling is to only eat fruit that you peel yourself, since plants can filter out bacteria and prevent it from traveling throughout their tissues. Well, why not apply this principle to filtering water directly? A team of scientists have done just that, testi... Read More
Exciting research suggests that a shot every one to three months may someday give an alternative to the daily pills that some people take now to cut their risk of getting HIV. The experimental drug has only been tested for prevention in monkeys, but it completely protected them from infection in... Read More
The science behind the transformation from plants to milk to cheese is amazing. In fact, cheese has much in common with wine and beer: They result from fermentation by microorganisms; they are “value-added” products where processing greatly increases the value; and they reflect local climate and...

A student and I painted with bacteria and this is what happened! We used a method similar to that used by artist Sarah Roberts (UK) and microbiologist Simon Park.
Motility agar plates were prepared and painted with watercolor paint before inoculation with P. aeruginosa. After 7 days at room t... Read More
Researchers have come a step closer to understanding how gonorrhea infections are transmitted. When Neisseria gonorrhoeae, the bacteria responsible for gonorrhea, are exposed to seminal plasma, the liquid part of semen containing secretions from the male genital tract, they can more easily move ...
