New small molecule compounds could treat Ebola virus infection

Scientists have discovered a new class of small molecule compounds that can block the Ebola virus's ability to break out of cells and infect new ones. The compounds target an interaction between the virus and host cells, inhibiting viral egress without being toxic to human cells.

The Lancet Global Health: Arab uprising has had long-term effect on health, lowering life expectancy in several countries

The Arab uprising and subsequent wars have had a devastating impact on the region's health, with many countries experiencing downward turns in life expectancy. The study reveals that infant mortality rates are rising, and chronic diseases such as diabetes and heart disease are becoming increasingly prevalent.

The origins of Cuban species

A research team from Hokkaido University suggests the Cuban solenodon family evolved around 59 million years ago, long after the dinosaur extinction. The species diverged from its ancestor and then traveled to Cuba via water, contradicting earlier theories.

Lymph node stage may have clinical significance among NSCLC patients with stage IV M1a

A large cohort of NSCLC patients with M1a disease found lymph node staging to have clinical significance and an impact on prognosis. The results showed that patients without regional lymph node metastasis (N0) had better lung cancer-specific survival rates compared to those with N1 or N2 disease. Lymph node involvement also emerged as ...

High-tech alternative to brain surgery proves effective for most common movement disorder

A clinical trial led by Jeff Elias at the University of Virginia Health System found that focused ultrasound is safe and effective in reducing shaking caused by essential tremor. Participants showed significant improvement in disabilities and quality of life, with mean tremor scores improving by 47% at three months.

Johns Hopkins scientists track metabolic pathways to find drug combination for pancreatic cancer

Scientists at Johns Hopkins have discovered a drug combination that specifically targets the metabolic pathways of pancreatic cancer cells. By combining an experimental drug with metformin, researchers were able to shrink tumors by at least 50% in animal models, providing new evidence for treating this aggressive form of cancer.

How long do you want to live? Your expectations for old age matter

A study found that young and middle-aged adults in the US prefer to live longer than average life expectancy if they have positive expectations for old age, but those with negative expectations prefer shorter lives. The study used a telephone survey of over 1600 adults aged 18-64 years and found no relationship between age, gender, or ...

Study takes a step back to look at use of restraints in hospitals

A recent study published in Journal of General Internal Medicine found that hospitals with adequate staffing levels, particularly registered nurses, experience reduced restraint use. The research suggests that the type of nursing staff rather than just total staffing is a crucial factor in preventing restraints from being used.

Global climate models do not easily downscale for regional predictions

Climate researchers found that global climate models become increasingly uncertain when making predictions at scales below approximately 600 miles for temperature changes and 1200 miles for precipitation patterns. This makes it difficult to predict regional variations, such as the difference in warming between Indianapolis and Pittsburgh.

Bio-inspired tire design: Where the rubber meets the road

Researchers at Lehigh University, Michelin Corporation, and NSF are developing materials with surface architectures that could enhance the safety and reliability of tires. By mimicking the smooth pad surfaces found on the feet of grasshoppers or frogs, they aim to improve sliding friction while minimizing rolling resistance.

A mystery of form and structure

Researchers built a stream table experiment to test a theory about the erosion of the Tarim Basin's flat surfaces. They found that channel switching played a crucial role in beveling these areas due to rapid changes in sediment flux and water flow. The study provides insights into the geological history of the region.
