Elizabeth Campbell studies the molecular machinery all living cells use to read and transcribe genetic instructions. Her lab finds new ways to block this critical machinery in bacteria and viruses.

ORNL employees volunteered with Second Harvest Food Bank of East Tennessee to pack 8,000 weekend food bags for children experiencing food insecurity through the Food for Kids program. The event is part of ORNL Gives, the laboratory’s annual employee giving and volunteer campaign, and builds on a partnership with Second Harvest that has supported East Tennessee communities for more than 20 years.

Researchers at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) and the University of Tennessee (UT), Knoxville, have made a scientific advance by using a natural substance from fungi, called chitin, to create hydrogels that are both significantly stronger and tougher. This new material could lead to safer medical devices, longer-lasting coatings and other innovations that improve everyday technology and health care. 

A study involving IITGN researchers tracked sediments released by mass-wasting events such as landslides in the Brahmaputra, with fine particles travelling more than 1000 km downstream and coarser particles affecting river morphology within approximately 100 km of the mountain front. In another study, the IITGN researchers found that dams on the Godavari are trapping much of the sediment that once reached the delta, threatening its stability and sustainability. These findings highlight the need to consider sediment movement for flood management, hydropower planning, and river and landscape management.

Researchers at IIT Gandhinagar have developed a computationally designed, copper- and zinc-free high-strength aluminium alloy with superior strength, excellent corrosion resistance, and good ductility. The research, led by Prof Amit Arora and PhD scholar Mr Sagar Kumar Deb, has reached Technology Readiness Level (TRL) 4 and is progressing towards industrial-scale validation. The work has earned international recognition through the prestigious Larry Kaufman Scholarship 2026 awarded to Mr Deb by CALPHAD Inc and has the potential to strengthen India's self-reliance in advanced engineering materials under the Make in India and Atmanirbhar Bharat initiatives.

Summary:

A 76.4 km² section of Greenland’s Petermann Glacier broke off on August 4, forming a Manhattan-sized ice island and marking the glacier’s largest calving event since 2012.

Researchers expect two more major ice islands to detach soon as existing fractures continue to expand, while scientists monitor the new iceberg for research and Arctic navigation safety.

This procedure employs surgically implanted subdermal electrodes combined with a specially designed wiring system that resists damage by unrestrained animals. The electrodes are secured beneath the skin to capture continuous electroencephalogram (EEG) and electrocardiogram (ECG) signals with a high signal-to-noise ratio. The wiring system is engineered to withstand the natural activities and movements of animals without compromising data fidelity. This innovation enables long-duration, uninterrupted recordings that provide comprehensive assessments surrounding episodic neurological and cardiac events.This technology addresses significant gaps in pre-clinical research by facilitating continuous physiological monitoring. Its design eliminates common problems such as electrode displacement and wiring failures, thereby enhancing experimental reliability and data quality. The protocol has been disclosed in academic documentation and published (Williams LG et al. JoVE 2025, PMC11951853), which also demonstrates the high-quality signal.

This University at Buffalo technology actively controls crystallization during evaporation by applying a controlled external electric field across evaporating electrolyte droplets, aerosols, sprays, or thin liquid films. The applied field polarizes the solution and generates electric double layers at liquid interfaces, redistributing dissolved ions away from the bulk solution and delaying supersaturation until later in the evaporation process. As a result, crystallization occurs at a smaller droplet volume, producing denser particles with reduced hollow-shell formation and improved microstructural uniformity.

Observed each August, Breastfeeding Awareness Month provides an opportunity to recognize the impact breastfeeding can have on the health and well-being of infants and mothers. In a Q&A, Dr. Brenda Ross-Shelton at UC Riverside Health discusses why breastfeeding is considered one of the best investments in a baby’s health -- and more.
