More than 20,000 women are diagnosed with ovarian cancer each year in the United States, most of whom have advanced disease. Although chemotherapy can put the disease into remission, it often recurs and the treatment’s effectiveness tends to wane over time. As a result, ovarian cancer is the fifth most-common cause of cancer death in women.

On Saturday, a team of researchers including Stanford oncologist Jonathan Berek, MD, presented the results of an international, multi-center phase-3 clinical trial of a new oral medication called niraparib in 553 women with advanced, recurrent ovarian cancer at the annual meeting of the European Society for Molecular Oncology in Copenhagen. Berek, the Laurie Kraus Lacob Professor and director of the Stanford Women’s Cancer Center, supervised Stanford’s involvement in the trial.

The aim of the study was to see whether niraparib could prolong the length of remission, also known as “progression-free survival,” in the women when compared to treatment with a placebo. As Berek described the niraparib treatment for me in an phone call, “This is a daily oral treatment with relatively low toxicity. Importantly, women don’t have to go to the hospital for regular infusions and are unlikely to experience significant hair loss.”

We are living in a world that is global and exponential. Technology is taking things that used to be scarce and making them abundant—and these forces are reshaping the fields of medicine and healthcare in completely novel ways.

Opening this year’s Exponential Medicine conference in San Diego, Daniel Kraft, the curator of the conference, and faculty chair of Medicine and Neuroscience at Singularity University, took the audience on a whirlwind tour of the latest developments in healthcare and medicine.

Lung cancer treatment is moving beyond chemotherapy, with Merck & Co. setting the pace in a new category of therapies that harness the body’s immune system to fight tumors.

The U.S. drugmaker’s drug Keytruda reduced the risk of death or cancer progression by 50 percent, Merck said, unveiling details of a crucial study at a meeting of the European Society for Medical Oncology. The medicine gave patients an average of 10.3 months before their cancer progressed, compared with six months on chemotherapy. Unlike competitor Bristol-Myers Squibb Co., whose similar drug Opdivo failed in an advanced trial and caused its stock to plunge, Merck selected patients who harbored high levels of a protein thought to predict how well the immune-system drugs will work.

The results give Merck a head start — and not just on Bristol-Myers. Roche Holding AG and AstraZeneca Plc are also in the race for the best new immune therapy against lung tumors, the most common cancer in the world. Doctors will probably start testing patients soon after diagnosis to see whether they’re suited to treatment with Keytruda and can forgo the many side effects of chemotherapy, said Stefan Zimmermann, a chief oncologist at the Cantonal Hospital of Fribourg, Switzerland.

Last week the U.S. corporation Monsanto, which holds a leading position in the global market of genetically modified organisms (GMOs), reached a licensing agreement with the Broad Institute, Cambridge, USA, on the commercial use of the innovative genome-editing technology CRISPR/Cas9 for agriculture applications. This news has led some experts to believe that Monsanto will now completely switch from producing ‘traditional’ GMOs to ‘genetically edited’ organisms, which are supposedly ‘safer and practically identical’ to their natural alternatives.

Let’s have a closer look at this technology which makes GMO supporters feel so enthusiastic and has been positioned by them as the universal panacea solving all of mankind’s problems. We will also delve deeper into some of the darker aspects of CRISPR/Cas9; the points that biotechnology lobbyists prefer not to discuss.

Neural Nanonics here we come: “Could lead to future autonomous, fully implantable neuroprosthetic devices”

A bio-inspired electronic device called a memristor could allow for real-time processing of neuronal signals (spiking events), new research led by the University of Southampton has demonstrated.

The research could lead to using multi-electrode array implants for detecting spikes in the brain’s electrical signals from more than 1,000 recording channels to help treat neurological conditions, without requiring expensive, high-bandwidth, bulky systems for processing data. The research could lead to future autonomous, fully implantable neuroprosthetic devices.

A great new biomarker for senescent cells is available and will allow researchers to more measure levels of aged cells easier and faster. Great news for gerontologists wishing to demonstrate changes to aged cell populations after therapies.


Scientists have discovered a new way to look for ageing cells across a wide range of biological materials; the new method will boost understanding of cellular development and ageing as well as the causes of diverse diseases.

Frustrated by the limitations of commercially available biomarkers — researchers led by The University of Manchester’s Professor Paul Townsend and senior author of the resulting paper, and honorary professor at Manchester, Professor Vassilis Gorgoulis, have developed a universally applicable method to assess senescence across biomedicine, from cancer research to gerontology.

Cellular senescence is a fundamental biological process involved in every day embryonic and adult life, both good – for normal human development – and, more importantly to researchers, dangerous by triggering disease conditions. Up to now available senescence detecting biomarkers have very limited and burdensome application. Therefore, a more effective, precise and easy-to-use biomarker would have considerable benefits for research and clinical practice.

In Brief.

  • Every year, more than 795,000 people in the United States have a stroke.
  • A team of scientists has discovered a common mechanism chain leading to brain cell death which involves proteins eating away at a cell’s DNA.

A team of scientists has discovered that, despite having varied causes and symptoms, most brain diseases all share a common mechanism chain leading to brain cell death. The process, aptly named parthanatos after an enzyme called PARP and the Greek god of death, involves proteins eating away at the cell’s DNA.
