Often patients undergo procedures without real informed consent being achieved due to technical language, jargon and time pressure, with up to half of patients finding it difficult to understand what their doctor tells them [1, 2]. Now a group of Australian doctors has prepared patients for surgery using iPads, and found that patients' understanding was much better than after a face-to-face consultation.

It is vitally important that patients understand what medical procedures they face, both so that they can cope better with the procedure, and so that they can give fully informed consent to the treatment. However, many patients come out of critical face-to-face interviews with doctors not really understanding what to expect or what they might have agreed to.

The use of meldonium--the substance taken by tennis star Maria Sharapova--is widespread among elite athletes, reveals research published online in the British Journal of Sports Medicine.

The findings, which draw on information volunteered by athletes and individual medical teams, and lab data on anti-doping tests from the Baku 2015 European Games, indicate that up to 490 athletes may have been taking meldonium during the competition.

The research, which was carried out on behalf of the European Olympic Committees, contributed to the World Anti-Doping Agency (WADA) taking the decision to ban the use of meldonium in competitive sport as of January 1 this year.

Doctors have long characterized epilepsy as a brain disorder, but researchers at Case Western Reserve University have found that part of the autonomic nervous system functions differently in epilepsy during the absence of seizures.

This connection to the involuntary division of the nervous system may have implications for diagnosing and treating the disease and understanding sudden unexpected death in epilepsy (SUDEP).

The research is published online in the Journal of Neurophysiology.

Researchers at University of California, San Diego School of Medicine and Shiley Eye Institute, with colleagues in China, have developed a new, regenerative medicine approach to remove congenital cataracts in infants, permitting remaining stem cells to regrow functional lenses.

The treatment, which has been tested in animals and in a small, human clinical trial, produced much fewer surgical complications than the current standard-of-care and resulted in regenerated lenses with superior visual function in all 12 of the pediatric cataract patients who received the new surgery.

The findings are published in the March 9 online issue of Nature.

SAN DIEGO, March 13, 2016 -- Electronics manufacturers constantly hunt for ways to make faster, cheaper computer chips, often by cutting production costs or by shrinking component sizes. Now, researchers report that DNA, the genetic material of life, might help accomplish this goal when it is formed into specific shapes through a process reminiscent of the ancient art of paper folding.

The researchers present their work today at the 251st National Meeting & Exposition of the American Chemical Society (ACS). ACS, the world's largest scientific society, is holding the meeting here through Thursday. It features more than 12,500 presentations on a wide range of science topics.

SAN DIEGO, March 13, 2016 -- Hops, those little cone-shaped buds that give beer its bitter flavor, pack a surprisingly healthful punch. They are widely studied for their ability to halt bacterial growth and disease. Now, researchers report that they are close to synthesizing the healthful hops compounds in the lab. This advance could one day help scientists create medicines from these compounds without having to extract them from plants.

SAN DIEGO, March 13, 2016 --Women can choose from a wide selection of birth control methods, including numerous oral contraceptives, but there's never been an analogous pill for men. That's not for lack of trying: For many years, scientists have attempted to formulate a male pill. Finally, a group of researchers has taken a step toward that goal by tweaking some experimental compounds that show promise.

EUGENE, Ore. -- (March 8, 2016) -- If you have trouble sleeping, the neurons in your brain may be firing like those in roundworms randomly seeking food in the absence of clues, says University of Oregon biologist Shawn R. Lockery.

That connection is proposed in a theoretical neuroscience paper co-authored by 12 researchers at 10 institutions that is in the journal eLife. The research -- 14 years in the making -- was led by Lockery and supported by the National Institutes of Health.

As humans sleep, neurons fire randomly in between brief, alternating states of wakefulness and sleep. Such fragmentation is heightened in sleep disorders.

Crowds formed from tiny particles disperse as their environment becomes more disordered, according to scientists from UCL, Bilkent University and Université Pierre et Marie Curie.

The new mechanism is counterintuitive and might help describe crowd behaviour in natural, real-world systems where many factors impact on individuals' responses to either gather or disperse.

"Bacterial colonies, schools of fish, flocking birds, swarming insects and pedestrian flow all show collective and dynamic behaviours which are sensitive to changes in the surrounding environment and their dispersal or gathering can be sometimes the difference between life and death," said lead researcher, Dr Giorgio Volpe, UCL Chemistry.

By now the entire world has heard that famed Russian tennis champion Maria Sharapova has tested positive for a banned substance. According to a March 9 Reuters article, she has been suspended, lost major sponsors and there is a possibility that she will miss the upcoming Olympics. The substance she was taking is Meldonium or Mildronate.

This is a heart medication that is most commonly used in Eastern Europe. This medication has been banned effective only this past January. Meldonium works by regulating the energy metabolism pathways. It has been used for treatment of heart failure, arrhythmia, heart attacks and diabetes. It has not been approved for use in the United States.
