Researchers examined that the millions of molecules bumping around in a cell "find" one another and organize into functional structures. So it was a big surprise in 2008 when participants in the Marine Biological Laboratory (MBL) Physiology course realized that simple phase separations like oil separating from water may be one important way to create order inside a cell. The study was published in Science.

Diagnoses of sexually transmitted diseases hit a record high in California last year — with sometimes deadly consequences, according to preliminary state data released this week.
A type of flavonoid found in dark-pigmented fruits like red grapes and blueberries may slow the lung function decline that occurs with aging. Previous research has shown that the plant-produced chemicals known as flavonoids have beneficial antioxidant and anti-inflammatory properties. Anthocyanins, the type of flavonoid investigated in the current study, have been detected in lung tissue shortly after being ingested, and in animals models of chronic obstructive pulmonary disease (COPD). The plant chemicals appear to reduce mucus and inflammatory secretions.
At least nine individuals have died due to the deadly Nipah virus in Kerala, India. Over 25 have been infected with this virus in the outbreak say official sources. Nipah virus is a deadly virus that spread rapidly among populations and has a death rate of between 40 to 75% infected individuals in previous outbreaks. Nipah is a newly emerged deadly virus that is typically hosted naturally by fruit bats and there is at present no cure or vaccine against this infection.
Iowa is tweaking its new state-funded family planning program that excludes abortion providers such as Planned Parenthood by restoring some eligibility to a large hospital system.
A new nanoparticle vaccine developed by MIT researchers could assist efforts to eradicate polio worldwide. The vaccine, which delivers multiple doses in just one injection, could make it easier to immunize children in remote regions of Pakistan and other countries where the disease is still found.
A study estimates that suicide is a significant national public health problem, especially among lung cancer patients and among veterans. They wanted to see if palliative care, which has been shown to improve quality of life, reduced suicides among veterans with stage IIIB and IV lung cancer.
The U.S. Food and Drug Administration approved Doptelet (avatrombopag) tablets to treat low blood platelet count (thrombocytopenia) in adults with chronic liver disease who are scheduled to undergo a medical or dental procedure. This is the first drug approved by the FDA for this use.
According to a study, researchers examined that the long-term safety and efficacy of oxymetazoline cream 1.0% in patients with rosacea with moderate-to-severe persistent erythema. Limited treatments are available for persistent erythema of rosacea. Oxymetazoline is safe and effective for the treatment of moderate-to-severe persistent erythema of rosacea. The study was published in the Journal of the American Academy of Dermatology.
Physicians at the University of Arizona College of Medicine—Tucson are developing a new tool that detects urine, or urethral, blockage. The technique may soon make it easier for patients to test themselves for the condition from the comfort of their own homes.
Clinicians in safety-net hospitals describe feeling moral distress and being driven toward professional burnout because of policies that prevent them from performing hemodialysis to undocumented immigrants, except in the case of an emergency. Being forced to provide inferior care due to the patient's immigration status was a significant burden to the clinicians who reported feeling a sense of admiration for these patients and a desire to advocate on their behalf. The study was published in Annals of Internal Medicine.
According to a new study, researchers have found a new way to see and measure protein assembly in real time and with unprecedented detail. This is revealed by using a new mode of atomic force microscopy, Proteins and molecules assemble and disassemble naturally as part of many essential biological processes. It is very difficult to observe these mechanisms, which are often complex and take place at the nanometer scale, far smaller than the normal visible range. The study was published in Nature Nanotechnology.
