2020 Subaru Forester Review: The Safety-First, Can’t-Go-Wrong-Buying-One Compact SUV

The 2020 Subaru Forester will likely not be the North American Car of the Year. (More probably the likes of the Audi e-Tron or Hyundai Palisade .) But for Subaru partisans who want safety, room for passengers and cargo, and rugged reliability, the Forester is the car of most every recent year. Even without 48-volt hybrid motors or active body control, the fifth-generation Forester brings a load o

Deconstructing Justice Terry Clackson’s outrageous acquittal of David and Collet Stephans for the death of their son Ezekiel

On September 19, in a retrial ordered by the Supreme Court of Canada, Alberta Justice Terry Clackson issued a ruling acquitting David and Collet Stephan of failing to provide the necessities of life to their son Ezekiel, whose bacterial meningitis they had chosen to treat with quackery instead of medicine, leading to his death in 2012.

Triplet-targeted therapy improves survival for patients with advanced colorectal cancer and BRAF mutations

The three-drug combination of encorafenib, binimetinib and cetuximab significantly improved overall survival (OS) in patients with BRAF-mutated metastatic colorectal cancer (mCRC), according to results of the BEACON CRC Phase III clinical trial led by researchers at The University of Texas MD Anderson Cancer Center.

Blood test can replace invasive biopsy for more patients with lung cancer

A growing number of patients with advanced lung cancer could soon be offered a blood test to help to decide the best treatment for them instead of having to get a tumour sample for analysis. New data from the BFAST trial presented at the ESMO Congress 2019 have shown that the test can be used successfully to identify complex DNA mutations in the cells of patients with NSCLC suitable for the latest

Brexit Imperils the World’s Oldest Political Party

Since the birth of the political party, in 17th-century England, perhaps none has been quite as unsuccessful in its constitutional struggle as the Tories. Time and again, this most English of interest groups has been on the wrong side of history, advocating for a status quo that has slowly been eroded by the steady tide of human advancement. And yet the Tories have survived at each turn, their ge

How newly found tension sensor plays integral role in aligned chromosome partitioning

A Waseda University-led research found that oncogene SET/TAF1, which was found to be a proto-oncogene of acute myeloid leukemia (AML), contributes to proper chromosome partitioning as a tension sensor. Additionally, abnormal SET protein disrupts tension sensor system at the centromere, leading to missegregation of the chromosomes and thereby cancer. These findings may lead to a discovery for a new

Question about fusion research

So I've been reading up on the various attempts to create power via fusion, and something hit me. Since so many of the experiments are very close to a net energy gain from fusion. Why not tap into one of the most powerful natural phenomena available to get us over the limit. My idea is that you would get the plasma to a certain point during a thunderstorm. Then when you want to kick things off. Y
