The promise of being able to quickly and accurately screen for diseases or chemical contaminants in a tiny drop of blood has long been an elusive goal. But scientist Daojing Wang says his company’s technology is up to the job. (more…)
There is no approved medicine to treat polyomaviruses, which afflict people with weakened immune systems, but scientists have found that a chemical compound called Retro-2 is able to reduce significantly the infectivity and spread of the viruses in lab cell cultures. Now they are working to improve it.
PROVIDENCE, R.I. [Brown University] — A team of scientists reports that a small-molecule compound showed significant success in controlling the infectivity and spread of three polyomaviruses in human cell cultures. To date there has been no medicine approved to treat such viruses, which prey on transplant recipients, people with HIV, and others whose immune systems have been weakened. (more…)
Environmental conditions have a much stronger influence on the mix of microbes living in various parts of your body than does competition between species. Instead of excluding each other, microbes that fiercely compete for similar resources are more likely to cohabit in the same individual.
This phenomenon was discovered in a recent study of the human microbiome – the vast collection of our resident bacteria, fungi, and other tiny organisms. (more…)
Deployment could lead transformation of toxic HAB monitoring
A new robotic sensor deployed by Woods Hole Oceanographic Institution (WHOI) in Gulf of Maine coastal waters may transform the way red tides or harmful algal blooms (HABs) are monitored and managed in New England. The instrument was launched at the end of last month, and a second such system will be deployed later this spring.
The results will add critical data to weekly real-time forecasts of New England red tide this year distributed to more than 150 coastal resource and fisheries managers in six states as well as federal agencies such as NOAA, the FDA and the EPA. Researchers also plan to add data from the sensor to regular updates provided on the “Current Status” page of the Northeast PSP website. (more…)
Opening the door to more sophisticated investigation of sperm locomotion and biophysics, researchers from UCLA’s Henry Samueli School of Engineering and Applied Science have identified previously unobserved swimming patterns in human and horse sperm cells.
This research, published in Scientific Reports, a journal of the Nature Publishing Group, could lead to a deeper understanding of how sperm move on their way to fertilization or other functions and how they react when encountering various toxins or chemicals. (more…)
COLUMBUS, Ohio — Though scientists have long believed that complex organic molecules couldn’t survive fossilization, some 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, Indiana, and Iowa have challenged that assumption.
The spindly animals with feathery arms—called crinoids, but better known today by the plant-like name “sea lily”—appear to have been buried alive in storms during the Carboniferous Period, when North America was covered with vast inland seas. Buried quickly and isolated from the water above by layers of fine-grained sediment, their porous skeletons gradually filled with minerals, but some of the pores containing organic molecules were sealed intact.

UCLA researchers, in a finding that runs counter to conventional wisdom, have discovered for the first time that a gene thought to express a stress-response protein in all cells that come under stress instead expresses the protein only in specific cell types.
The research team, from the Jules Stein Eye Institute at UCLA and the UCLA Division of Pulmonary and Critical Care Medicine, focused on αB-Crystallin, one of a class of molecules known as heat shock proteins, which are involved in the folding and unfolding of other proteins, helping them recover from stress so they can do their job.

Pollution is an unfortunate by-product of our ever-changing society. Air, water and even noise pollution can take a toll on any person’s body, without their knowledge. Fortunately, there ARE ways to fight the effects of pollution in your body, in order to maintain a healthy lifestyle. There are also helpful tips to decrease the toxins that are invading your body, which could potentially cause harmful consequences later in life. Here’s what you need to know!
The Consequences of Pollution
Impure surroundings affect the lungs, heart, cardiovascular system, immune system, and organs when dangerous toxins are inhaled, consumed or absorbed by the skin or airways. Respiratory ailments, such as colds, flu, pneumonia, emphysema and bronchitis occur often because of these. The chances of contracting asthma and COPD or Chronic Obstructive Pulmonary Disease are also more likely. Tainted environments also contribute to allergies, headaches, migraines, and skin disorders such as eczema, acne, melanoma cancer and premature aging. (more…)
