AI may predict spread of lung cancer to brain
Washington University in St. Louis

Scientists at Washington University School of Medicine in St. Louis trained a machine-learning algorithm to predict accurately brain metastasis using biopsy samples from early-stage non-small cell lung cancer patients. It was also highly accurate in predicting those patients who do not develop metastatic brain tumors.

Alzheimer’s blood test performs as well as FDA-approved spinal fluid tests
Washington University in St. Louis

Scientists report a major step toward a simple blood test for Alzheimer’s disease. Researchers at Washington University School of Medicine in St. Louis and Lund University in Sweden showed that a blood test is as good at identifying people in early stages of the disease as cerebrospinal fluid tests approved by the Food and Drug Administration (FDA) for Alzheimer’s diagnosis. The findings indicate that a blood test soon may replace more expensive and invasive brain scans and spinal taps for detecting signs of Alzheimer’s in the brain.

The ties that bind
Washington University in St. Louis

In a study published in the journal Environmental Science & Technology, WashU researchers discovered that a common mineral called goethite — an iron-rich mineral that is abundant in soils that cover the Earth — tends to incorporate trace metals into its structure over time, binding the metals in such a way that it locks them out of circulation.

WashU Expert: VC bust? Time to return to fundamentals in 2024
Washington University in St. Louis

After years of record investments and outsized returns fueled by ultralow interest rates, 3,200 U.S. private venture-backed companies — mostly tech startups — went out of business last year. Doug Villhard at Washington University in St. Louis' Olin Business School said the bust will cause the industry to reassess what is really important.

Samples from a Wild comet reveal a surprising past
Washington University in St. Louis

Eighteen years after NASA’s Stardust mission returned to Earth with the first samples from a known comet, the true nature of that icy object is coming into focus. Stardust collected material from Wild 2, a comet that likely formed beyond Neptune and currently orbits the sun between Mars and Jupiter. Painstaking analyses of the microscopic samples, recently described in the journal Geochemistry, have revealed a surprising truth about the comet’s origins and history, said Ryan Ogliore, an associate professor of physics in Arts & Sciences at Washington University in St.

Life span increases in mice when specific brain cells are activated
Washington University in St. Louis

A new study from Washington University School of Medicine in St. Louis identifies, in mice, a critical communication pathway connecting the brain and the body’s fat tissue in a feedback loop that appears central to energy production throughout the body. The research suggests that the gradual deterioration of this feedback loop contributes to the increasing health problems that are typical of natural aging.

Why do we sleep? Researchers propose an answer to this age-old question
Washington University in St. Louis

Sleep is a fundamental need, just like food or water. “You’ll die without it,” said Keith Hengen, an assistant professor of biology at Washington University in St. Louis. But what does sleep actually accomplish? For years, the best researchers could say is that sleep reduces sleepiness — hardly a satisfying explanation for a basic requirement of life.
