Dartmouth researchers offer new insights into how maternal immunity impacts neonatal HSV

Researchers found that vaccinated mothers can protect their newborns from neonatal herpes, a disease that can cause brain damage and death. The study also identified two scenarios that are particularly dangerous for newborns: acquiring genital herpes late in pregnancy or exposure to the virus through non-protected contact.

CSI meets conservation

Researchers at Stanford University and India's National Centre for Biological Sciences have developed a new approach to extract genetic clues from degraded DNA samples. This method uses a sequencing technique that amplifies small bits of DNA with unique differences in each sample, allowing for the use of contaminated or mixed samples. ...

Human iPSC-derived MSCs from aged individuals acquire a rejuvenation signature

Researchers have discovered that human iPSC-derived MSCs (iMSCs) from aged individuals acquire a rejuvenation-associated 50-gene signature, which is also expressed in pluripotent stem cells. This finding highlights the potential of iMSCs to act via paracrine signalling and circumvent drawbacks associated with adult MSCs.

Water that never freezes

Researchers at ETH Zurich have identified a novel way to prevent water from forming ice crystals by creating a new class of lipids that form a 'soft' biological matter. This material confines water in narrow channels, preventing it from freezing even at extreme sub-zero temperatures.

More than a strip of paint needed to keep cyclists safe

A study published in Accident Analysis and Prevention found that marked on-road bicycle lanes and parked cars do not provide enough space for safe passing. The research, which analyzed over 18,000 vehicle passing events, suggests that a single stripe of paint is insufficient to protect cyclists.

The protein p38gamma identified as a new therapeutic target in liver cancer

Researchers at CNIC have discovered that the protein p38gamma plays an essential role in initiating cell division in liver cells, making it a promising therapeutic target for liver cancer. The study found that inhibiting p38gamma slows down the development of liver cancer in mice, suggesting potential treatment options.

How severe drought influences ozone pollution

Researchers analyzed data from Fresno and Bakersfield before, during, and after the California drought to understand its impact on ozone air quality. They found that severe drought conditions led to a 20% decrease in ozone production due to reduced isoprene concentrations and altered VOCs.

Scientists find self-healing catalyst for potential large-scale use in hydrogen production

Researchers have developed a self-healing catalyst, SION-X, that can efficiently release hydrogen from ammonia borane, a promising energy carrier. The catalyst is based on abundant mineral Jacquesdietrichite and can be easily regenerated, stored, and handled, making it suitable for large-scale applications.
