Drinking bone broth is a recent diet fad that proponents claim fights inflammation, eases joint pain and promotes gut health. Simmering animal bones in water releases collagen and other proteins into the broth that may have health benefits, although more research is needed to validate these claims. Now, a new study in ACS’ Journal of Agricultural and Food Chemistry has shown that ham bones contain peptides that could have cardioprotective effects.
In new research that could help inform development of new materials, Cornell chemists have found that the empty space (“pores”) present in two-dimensional molecular building blocks fundamentally changes the strength of these van der Waals forces, and can potentially alter the assembly of sophisticated nanostructures.

Both the students and laboratory staff say the internships yielded positive results.
The holiday season can be a time of excess, but low- or no-calorie sweeteners could help merry-makers stay trim. Stevia is a zero-calorie sweetener that is sometimes called “natural” because it is extracted from the leaves of a South American plant. Now, a report in ACS Synthetic Biology describes a way to prepare large quantities of stevia using yeast, which would cut out the plant middleman and could lead to a better tasting product.
Many of us view the year’s end as a time for reflection, and chemists are no different. As we say goodbye to 2018, Chemical & Engineering News (C&EN), the weekly news magazine of the American Chemical Society, highlights the year’s biggest chemistry trends, most memorable molecules and more in a special issue. As part of its wrap-up, the magazine peers into its crystal ball to predict the hottest chemistry advances to watch for in 2019.
CRISPR allows scientists to precisely target and edit DNA within living cells, which could help them correct anomalies that cause inherited diseases.

A discovery by researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the Joint Center for Artificial Photosynthesis shows that recycling carbon dioxide into valuable chemicals and fuels can be economical and efficient – all through a single copper catalyst.
Despite the looming ecological consequences, glacier motion remains poorly understood. The roughness of bedrock, the temperature of the ice-bed interface and the presence of water-filled cavities all affect friction and influence how the ice will flow, but studying these factors poses unique challenges -- remote radar sensing by satellites and aircraft can track glacial movement, but it can’t peer through thousands of feet of ice to measure detailed properties of the ice and rock. In The Journal of Chemical Physics, Bo Persson describes a new model of ice friction that offers crucial insight into glacier flows.

Goddard III and Saber Naserifar from the California Institute of Technology describe their novel approach to building a new description of water (known as a force field) and demonstrate its accuracy.
Medical researchers at Melbourne's Murdoch Children's Research Institute have made a new discovery about how a baby's sex is determined - it's not just about the X-Y chromosomes, but involves a 'regulator' that increases or decreases the activity of genes which decide if we become male or female.
The formation of new aerosol particles is a complicated process. Researchers have only recently started to understand this process on a molecular level after instruments able to detect nanometer-scale particles became available.
When infants are playing with objects, their early attempts to pay attention to things are accompanied by bursts of high-frequency activity in their brain. But what happens when parents play together with them? New research, publishing December 13 in the open-access journal PLOS Biology, by Dr Sam Wass of the University of East London in collaboration with Dr Victoria Leong (Cambridge University and Nanyang Technological University, Singapore) and colleagues, shows for the first time that when adults are engaged in joint play together with their infant, their own brains show similar bursts of high-frequency activity. Intriguingly, these bursts of activity are linked to their baby’s attention patterns and not their own.
