For the association between nutrient intake and the risk of death, the researchers found:

Adequate intake of certain nutrients is associated with a reduction in all-cause mortality when the nutrient source is foods, but not supplements, according to a new study. There was no association between dietary supplement use and a lower risk of death.

In addition, excess calcium intake was linked to an increased risk of cancer death, which the researchers found was associated with supplemental doses of calcium exceeding 1,000 mg/day. The study was published on April 9 in Annals of Internal Medicine.

A new cancer “vaccine” that’s injected directly into a single tumor can trigger the immune system to attack cancer cells throughout the body, a small new study suggests.

The researchers say that the experimental therapy essentially turns tumors into “cancer vaccine factories,” where immune cells learn to recognize the cancer before seeking it out and destroying it in other parts of the body. “[We’re] seeing tumors all throughout the body melting away” after injecting just one tumor, said lead study author Dr. Joshua Brody, director of the Lymphoma Immunotherapy Program at the Icahn School of Medicine at Mount Sinai in New York.

Still, the research, published today (April 8) in the journal Nature Medicine, is very preliminary. The therapy has only been tested in 11 patients with non-Hodgkin’s lymphoma (a cancer of immune system cells), and not all of these patients responded to the treatment. But some patients did have remission for relatively long periods, and the results were promising enough that the therapy is now also being tested in patients with breast and head and neck cancers, the authors said.

Bacteria’s ability to develop antibiotic resistance is well known — but it turns out fungi are also evolving to withstand modern medicine.

Now one such fungus is cropping up in hospitals all across the globe and killing half the people who contract it within 90 days, according to an alarming story by The New York Times — raising concerns about a new global epidemic.

Great white sharks—one of the ocean’s most fearsome apex predators—thrive with toxic levels of poisons flowing in their veins, according to a new study by OCEARCH.

Researchers recently came to that conclusion after taking blood samples from 40 white sharks off South Africa, according to an April 3 report on OCEARCH.org.

The samples revealed “alarmingly high levels of poisonous heavy metals, like arsenic and mercury, in sharks’ blood,” says the report.

With new genome analysis tools, scientists have made significant advances in our understanding of modern humans’ origins and ancient migrations.

But trying to find ancient DNA, let alone prove that the ancient DNA is ancestral to a population living today is extremely challenging.

A new study in Molecular Biology and Evolution (MBE) adds to this understanding by reconstructing artificial genomes with the analyses of the genome of 565 contemporary South Asian individuals to extract ancient signals that recapitulate the long history of human migration and admixture in the region.

A permanent neural implant that reads brain activity and churns out text could prove to be a valuable medical tool, but it also could provide doctors with an unprecedented 24/7 stream of neural data.

Oxley recognizes that an endless feed of brain activity could be invaluable to medical researchers, but he doesn’t have plans to tap into that yet.

“[The Stentrode is] going to show us information that we hadn’t had before. Whether that helps us understand other things is not what we’re trying to do here,” he said, clarifying that Synchron’s primary goal is to get the new brain-computer interface working so that it can help paralyzed patients. “This is a novel data set, but this raises questions around privacy and security. That’s the patient’s data, and we can’t be mining that.”

Though signs point to bispecifics, like other immunotherapies, eliminating cancer in a small fraction of people, there are hints they could help many more.

Manfred Eigen, who has died aged 91, was a phenomenally versatile German chemist and physicist who founded two major scientific disciplines, first in chemical reaction kinetics and later in the development of a molecular approach to evolutionary biology.

He also co-founded two biotechnology companies – Evotec, now a €3.29 billion concern, and Direvo, which was acquired by Bayer Healthcare for $300 million in 2008.
