SAN DIEGO, CA--Commonly, we think of cancer as anarchy, a leaderless mob of deranged cells, storming through the body. Pedro Lowenstein, Sebastien Motsch, and colleagues at the University of Michigan and University of Arizona think that cancer is highly organized--self-organized. In brain cancer, the Michigan and Arizona researchers report that glioma cells build tumors by self-organizing into streams,10-20 cells wide, that obey a mathematically predicted pattern for autonomous agents flowing together. These streams drag along slower gliomas, may block entry of immune cells, and swirl around a central axis containing glioma stem cells that feed the tumor's growth.

Gillnetting around the world is ensnaring hundreds of thousands of small cetaceans every year, threatening several species of dolphins and porpoises with extinction, according to research presented at the Society of Marine Mammalogy's 21st biennial conference in San Francisco this week.

But there is one bright spot in the Gulf of California, where Mexican authorities earlier this year instituted an emergency two-year ban on gillnetting to help save the critically endangered vaquita, now the rarest marine mammal species on the planet. Fewer than 100 vaquita remain, scientists speaking at the conference said.

Using antidepressants during pregnancy greatly increases the risk of autism, Professor Anick Bérard of the University of Montreal and its affiliated CHU Sainte-Justine children's hospital revealed today. Prof. Bérard, an internationally renowned expert in the fields of pharmaceutical safety during pregnancy, came to her conclusions after reviewing data covering 145,456 pregnancies. "The variety of causes of autism remain unclear, but studies have shown that both genetics and environment can play a role," she explained.

BOSTON -- Non-small cell lung cancer (NSCLC) in younger patients is a distinct disease, genetically and biologically, from NSCLC in older patients and may require a different treatment approach, Dana-Farber Cancer Institute scientists have found.

In a study published online today by JAMA Oncology, investigators scanned the DNA of thousands of NSCLC tumor samples for abnormalities and found that younger patients were more apt to have genetic subtypes of the disease that can be treated with available targeted therapies.

One of the biggest controversies in the western U.S. in the last two decades has been keeping gray wolves listed as endangered. Wolves are predators and with no evidence-based policies regarding herd management, attacks on livestock and threats to humans were greater than ever. That changed recently because the US Fish and Wildlife Service implemented herd management to try and bring the population back down. 

If you are in science, the genome editing method called CRISPR  is not new, it has been all the rage since 2012 because of its superior ability of CRISPR to deliver a gene to the right spot compared to its genome editing competitors.

A study sheds new light on how the tilt of the Earth affects the world's heaviest rainbelt and ths the climate overall. Data from the past 282,000 years shows a connection between the Earth's tilt, called obliquity, that shifts every 41,000 years, and that the movement of a low pressure band of clouds that is the Earth's largest source of heat and moisture -- the Intertropical Convergence Zone.

Thick donut-shaped disks of gas and dust that surround most massive black holes in the universe are 'clumpy' rather than smooth as originally thought, according to a new study.

Until recently, telescopes weren't able to penetrate some of these donuts, also known as tori, which feed and nourish the growing black holes tucked inside.

Taking certain antidepressants for depression is linked to a heightened risk of subsequent mania and bipolar disorder, reveals research published in the online journal BMJ Open.

The strongest association seemed to be for serotonin reuptake inhibitors, or SSRIs for short, and the dual action antidepressant venlafaxine, the analysis indicated.

The researchers base their findings on the anonymised medical records of more than 21,000 adults in receipt of treatment for major (unipolar) depression between 2006 and 2013 at a large provider of inpatient and community mental healthcare in London.

New research shows a cereal familiar today as birdseed was carried across Eurasia by ancient shepherds and herders laying the foundation, in combination with the new crops they encountered, of 'multi-crop' agriculture and the rise of settled societies. Archaeologists say 'forgotten' millet has a role to play in modern crop diversity and today's food security debate.

The domestication of the small-seeded cereal millet in North China around 10,000 years ago created the perfect crop to bridge the gap between nomadic hunter-gathering and organised agriculture in Neolithic Eurasia, and may offer solutions to modern food security, according to new research.
