Pipeline owners Dominion and Duke Energy announced Sunday they were cancelling the fossil fuel project due to mounting delays and uncertainty. They said the many legal challenges to the project had driven up the projected costs by almost half, from $4.5 to $5 billion when it was first announced in 2014 to $8 billion according to the most recent estimate.

Environmental and community groups, who have long opposed the project on climate, conservation and racial justice grounds, welcomed the news.

Having hypertension in midlife (ages 40 through 60) is associated with elevated risk of cognitive impairment and Alzheimer’s dementia later in life, even more so than having the so-called Alzheimer’s gene.

“It is clear that cerebral vascular disease”—that is, hardening of the arteries inside our brain—“and cognitive decline travel hand in hand,” something I’ve addressed before. “However, the independent association of AD [Alzheimer’s disease] with multiple AVD [atherosclerotic vascular disease] risk factors suggests that cholesterol is not the sole culprit in dementia.”

As I discuss in my video Higher Blood Pressure May Lead to Brain Shrinkage, one of the most consistent findings is that elevated levels of blood pressure in midlife, ages 40 through 60, is associated with elevated risk of cognitive impairment and Alzheimer’s dementia later in life—in fact, even more so than having the so-called Alzheimer’s gene.

An antibody cocktail designed to prevent and treat COVID-19 is now entering late-stage clinical trials, according to reports.

When naturally infected with COVID-19, the body generates Y-shaped molecules called antibodies that latch onto the virus and mark it for destruction, or hinder its ability to infect healthy cells, Live Science previously reported. These antibodies can be drawn from recovered COVID-19 patients and injected into sick patients to bolster their immune systems against the virus, a treatment known as convalescent plasma therapy.

Google is now the fourth Big Tech company to beat the milestone.

Gaithersburg, Md.-based Novavax said the funding will allow the company to participate in Operation Warp Speed, the government’s program that has a goal of supporting the development of hundreds of millions of vaccine doses by 2021. The funding granted to Novavax will support the late-stage clinical development of the vaccine candidate, including a pivotal Phase III study. Additionally, the funds will be used to establish large-scale manufacturing in order to deliver 100 million doses of NVX‑CoV2373 by the end of the year.

Stanley C. Erck, president and chief executive officer of Novavax, said the company was honored to partner with Operation Warp Speed, a program that is supporting multiple shots on goal against COVID-19 by backing multiple vaccine projects, including Moderna’s mRNA program and AstraZeneca’s vaccine candidate.

“The pandemic has caused an unprecedented public health crisis, making it more important than ever that industry, government and funding entities join forces to defeat the novel coronavirus together. We are grateful to the U.S. government for its confidence in our technology platform, and are working tirelessly to develop and produce a vaccine for this global health crisis,” Erck said in a statement.

Study after study has shown that statins can prevent heart attacks, strokes and death in middle-aged adults. But in 28 major clinical trials of statins, only 2 percent of participants have been 75 years or older. This means that even though older adults are at greater risk of heart disease and death, there is scant data on whether statins should be prescribed for them.

A new study led by investigators from Brigham and Women’s Hospital and VA Boston Healthcare System leverages national data from the U.S. Veterans Health Administration Services and Centers for Medicare & Medicaid Services to shed new light on the role statins may play for older adults who have not yet experienced a heart attack, stroke or other cardiovascular event. In their retrospective analysis, the researchers found that the risk of dying from any cause was lower by 25 percent among veterans who were using statins compared to those who were not treated with statins. The risk of dying from a cardiovascular event, such as a heart attack or stroke, was lower by 20 percent. The team’s results are published in JAMA.

“Based on these data, age is not a reason to not prescribe statins,” said lead and corresponding author Ariela Orkaby, MD, MPH, a physician scientist at VA Boston Health Care System and in the Division of Aging at the Brigham. “Statins are commonly studied and prescribed for middle-aged adults but understudied in people over age 75. One of the most remarkable things about our results is that we found the benefit of statins held true regardless of whether a person was older or younger or had a condition such as dementia.”

There is no really useful treatments for Pancreatic Cancer, also it’s really deadly. So this sounds like awesome science news! “Cancer cells in the pancreas seem to thrive off this hyperactive cholesterol synthesis. The team thinks this is probably because they are taking advantage of other molecules generated by the same pathway. They’re able to keep the pathway running and maintain their supply thanks to an enzyme called sterol O-acyltransferase 1 (SOAT1), which converts free cholesterol to its stored form and which pancreatic cancer cells have in abundance.” “When the researchers eliminated the SOAT1 enzyme through genetic manipulation, preventing cells from converting and storing their cholesterol, cancer cells stopped proliferating. In animal experiments, eliminating the enzyme stalled tumor growth.”

Scientists at Cold Spring Harbor Laboratory (CSHL) have found that they can stop the growth of pancreatic cancer cells by interfering with the way the cells store cholesterol. Their findings in mice and lab-grown pancreas models point toward a new strategy for treating the deadly disease.

The study, reported in the Journal of Experimental Medicine, was led by CSHL Professor David Tuveson’s team wanted to know why pancreatic cancer cells, like many cancer cells, manufacture abundant amounts of cholesterol. Cholesterol is an essential component of cell membranes, but the research team determined that pancreatic cancer cells make far more of it than they need to support their own growth. “This is unusual, because the cholesterol pathway is one of the most regulated pathways in metabolism,” says Tobiloba Oni, a graduate student in Tuveson’s lab.
