Scientists develop and monitor two approaches to fix blood vessel abnormalities that make tumors difficult to treat

Abnormal tumor blood vessels promote cancer progression and treatment resistance. Researchers have developed two approaches to repair tumor blood vessels and they have devised a method to measure the effects of these approaches. Combining the approaches may be an effective strategy for fixing blood vessel abnormalities that make tumors difficult to treat.

Industry lobbying on WHO overshadowing public health policy, researchers suggest

Has the World Health Organization become collateral damage in the wars over global commerce? Producers of such products as commercial milk formulas, processed foods, alcoholic beverages, pharmaceuticals and electronic gaming software have been ramping up efforts to influence United States policy toward the WHO. This, University of California, Davis researchers suggest in a new paper, compromises a...

First direct observation of the dead-cone effect in particle physics

The ALICE collaboration at the Large Hadron Collider (LHC) has made the first direct observation of the dead-cone effect—a fundamental feature of the theory of the strong force that binds quarks and gluons together into protons, neutrons and, ultimately, all atomic nuclei. In addition to confirming this effect, the observation, reported in a paper published today in Nature, provides direct...

Brain capital: A new investment approach for late-life well-being

Within many societies and cultures around the world, older adults are too often undervalued and underappreciated, according to a new article. This exacerbates many key challenges that older adults may face. It also undermines the many positive aspects of late life that are of value at both an individual and societal level. In the article, 'Investing in Late-Life Brain Capital,' a global team of...

Sparking sustainable new chemical catalysts

New research could lead to the creation of new, sustainable catalysts based on tungsten oxide and similar compounds. The project used computational simulations to understand how tungsten oxide interacts with hydrogen at the molecular level and the findings were verified through lab experimentation.

Accelerating the pace of machine learning

Machine learning happens a lot like erosion. Data is hurled at a mathematical model like grains of sand skittering across a rocky landscape. Some of those grains simply sail along with little or no impact. But some of them make their mark: testing, hardening, and ultimately reshaping the landscape according to inherent patterns and fluctuations that emerge over time. Effective? Yes. Efficient? Not...

Molecular surveillance pathway tells cells when they run low on lipids

UT Southwestern researchers have discovered a molecular pathway that allows cells to sense when their lipid supplies become depleted, prompting a flurry of activity that prevents starvation. The findings, reported in Nature, might someday lead to new ways to combat metabolic disorders and a variety of other health conditions.

NBA sees rise in acts of symbolic violence, decline in acts of physical violence

A new analysis of NBA basketball broadcasts from 1998 to 2018 reveals a decline in acts of physical violence, such as pushing and elbowing, and a rise in acts of symbolic violence, such as shouting, trash talking, and menacing displays. Assaf Lev from the Department of Sports Therapy at Ono Academic College in Kiryat Ono, Israel, and colleagues present these findings in the open-access journal...

Research team develops wood-based foam to keep buildings cooler

Summertime is almost here, a time when many people try to beat the heat. But running air conditioners constantly can be expensive and wasteful. Now, researchers reporting in the ACS journal Nano Letters have designed a lightweight foam made from wood-based cellulose nanocrystals that reflects sunlight, emits absorbed heat and is thermally insulating. They suggest that the material could reduce...
