New way to spot beetle-killed spruce can help forest, wildfire managers

Science Daily - 13/06/2024
A new machine-learning system can automatically produce detailed maps from satellite data to show locations of likely beetle-killed spruce trees in Alaska, even in forests of low and moderate infestation where identification is otherwise difficult. The automated process can help forestry and wildfire managers in their decisions. That's critical as the beetle infestation spreads.

Four new studies report progress towards long-awaited HIV vaccine

The Hindu:Science - 13/06/2024
Researchers have unearthed two promising vaccine candidates that could engage B-cells to make broadly neutralising antibodies to attack HIV

Pacific coast gray whales have gotten 13% shorter in the past 20-30 years, Oregon State study finds

Science Daily - 13/06/2024
Gray whales that spend their summers feeding in the shallow waters off the Pacific Northwest coast have undergone a significant decline in body length since around the year 2000, a new study found.

Risk of secondary cancers after CAR-T cell therapy low, according to large study

Science Daily - 13/06/2024
In April, the FDA warned of risk of secondary cancers in people receiving CAR-T cell therapy. A large study now finds the risk is low and not related to the CAR-T cells.

Western agricultural communities need water conservation strategies to adapt to future shortages

Science Daily - 13/06/2024
The Western U.S. is heavily reliant on mountain snowpacks and their gradual melt for water storage and supply, and climate change is expected to upend the reliability of this natural process. Many agricultural communities in this part of the country are examining ways to adapt to a future with less water, and new research shows that a focus on supplementing water supply by expanding reservoir capacity won't be enough to avert future water crises.

Does having a child with low birth weight increase a person's risk of dementia?

Science Daily - 13/06/2024
People who give birth to infants less than 5.5 pounds may be more likely to have memory and thinking problems later in life than people who give birth to infants who do not have a low birth weight, according to a new study. The effect on memory and thinking skills was equivalent to one to two years of aging for those with low-birth-weight deliveries.

Depressive symptoms in young adults linked to thinking, memory problems in midlife

Science Daily - 13/06/2024
People who experience prolonged depressive symptoms starting in young adulthood may have worse thinking and memory skills in middle age, according to a new study. The study also found that depressive symptoms were experienced more often by Black adults than white adults.

Exposure to heat and cold in early life may affect development of white matter in the brain

Science Daily - 13/06/2024
Brain scans of more than 2,000 preadolescents suggests that early life exposure to heat and cold may have lasting effects on the microstructure of white matter in the brain, especially when living in poorer neighborhoods. The study highlights the vulnerability of fetuses and children to extreme temperatures.

NASA's Roman mission gets cosmic 'sneak peek' from supercomputers

Swimming microrobots deliver cancer-fighting drugs to metastatic lung tumors in mice

Science Daily - 13/06/2024
Engineers have developed microscopic robots, known as microrobots, capable of swimming through the lungs to deliver cancer-fighting medication directly to metastatic tumors. This approach has shown promise in mice, where it inhibited the growth and spread of tumors that had metastasized to the lungs, thereby boosting survival rates compared to control treatments.

Mouse study identifies unique approach for preventing life-threatening complications after spinal cord injury

Science Daily - 13/06/2024
A new study identifies a druggable cellular target that, if controlled properly, could prevent or lessen autonomic dysfunction and improve quality of life for people with spinal cord injury.

Mobile monitoring for an airborne carcinogen in Louisiana's 'Cancer Alley'

Science Daily - 12/06/2024
Louisiana's southeastern corridor is sometimes known colloquially as 'Cancer Alley' for its high cancer incidence rates connected to industrial air pollution. Most of the region's air pollution-related health risks are attributed to ethylene oxide, a volatile compound used to make plastics and sterilize medical equipment. Researchers measured concerning levels of ethylene oxide in this area with mobile optical instruments, a technique they say could improve health risk assessments.

Soaring birds use their lungs to modify mechanics of flight

Science Daily - 12/06/2024
An air-filled sac within the birds' lungs is believed to increase the force the birds use to power flight muscles while soaring.

What the geologic record reveals about how oceans were oxygenated 2.3 billion years ago

Science Daily - 12/06/2024
Geochemists used thallium isotopes to track the rise and fall of free oxygen on Earth between 2.5 and 2.2 billion years ago, the process that enabled life as we know it.

Putting the brakes on chronic inflammation

Science Daily - 12/06/2024
Scientists have discovered a previously unknown link between two key pathways that regulate the immune system in mammals -- a finding that impacts our understanding of chronic inflammatory bowel diseases (IBD). This family of disorders severely impacts the health and quality of life of more than 2 million people in the United States.

Laser tests reveal new insights into key mineral for super-Earths
