UCLA neurobiologists identify brain cells that control breathing

Researchers identified a small group of neurons responsible for issuing breathing commands within the preBotzinger Complex. Destroying these neurons in rats resulted in irregular breathing patterns and impaired oxygen control, suggesting they hold underlying causes of breathing disorders.

Researchers building a trap for chromium six

Virginia Tech researchers have created a Selective Ion Trap (SIT) device that can capture and preserve chromium six in the field, enabling faster and more accurate analysis of contaminated groundwater. The device uses a plastic membrane to trap chromium six without allowing it to transform into less reactive forms.

Researchers closer to delivering new insulin pill for diabetics

Researchers at Purdue University have demonstrated a method for delivering insulin orally using microscopic particles that protect the medicine from stomach acid until they can be released in the intestines. The system has been shown to be non-toxic and effective, with the potential to revolutionize treatment for insulin-dependent diab...

Anker Laptop Power Bank 25,000mAh (Triple 100W USB-C) keeps Macs, tablets, and meters powered during extended observing runs and remote surveys.

Clay reduces permeability of biomedical polymer

Scientists at Penn State have developed a new method to reduce the permeability of biomedical polymers using silicate clay, achieving a significant improvement in air and water resistance. The clay is mixed with the polymer in a common solvent, resulting in a barrier that effectively blocks many paths for air and water migration.

Hypnosis may give false confidence in inaccurate memories

A study suggests that hypnosis doesn't enhance the reliability of memory, but increases confidence in inaccurate memories. Researchers found that students under hypnosis were more reluctant to change their answers when told they might be wrong, indicating a higher level of confidence in their estimates.

New food packaging technique improves quality, extends shelf life

A new food packaging technique using argon gas has been shown to extend the shelf life of foods by 25% and improve their overall quality, with some products seeing a 40-50% improvement. Argon replaces nitrogen, which causes food to oxidize and spoil, making it a safe and effective way to preserve food.
