Acoustic recordings of a colony of little auks reveal their nocturnal activities and offer valuable monitoring means for avian biology in the Arctic.
The stress-induced mechanisms that cause our brain to produce feelings of fear in the absence of threats — such as in PTSD — have been mostly a mystery. Now, neurobiologists have identified the changes in brain biochemistry and mapped the neural circuitry that cause generalized fear experiences.
A recent study observing wild chimpanzees over a period of more than 10 years revealed that when food gets scarcer, the adults put play aside and focus on survival, while mother chimps continue to be their children’s primary playmate – suggesting their indispensable role to foster their young’s physical and social development
A blood test intended for screening for colorectal cancer in people who are of average risk and not experiencing symptoms correctly detected colorectal cancer in 83% of people confirmed to have the disease, according to a study published March 14 in the New England Journal of Medicine.
Space travel and zero gravity can take a toll on the body. A new study has found that astronauts with no prior history of headaches may experience migraine and tension-type headaches during long-haul space flight, which includes more than 10 days in space. The study was published in the March 13, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Repeats of DNA sequences, often referred to as “junk DNA” or “dark matter,” that are found in chromosomes and could contribute to cancer or other diseases have been challenging to identify and characterize. Now, investigators at the Johns Hopkins Kimmel Cancer Center have developed a novel approach that uses machine learning to identify these elements in cancerous tissue, as well as in cell-free DNA (cfDNA) — fragments that are shed from tumors and float in the bloodstream. This new method could provide a noninvasive means of detecting cancers or monitoring response to therapy. Machine learning is a type of artificial intelligence that uses data and computer algorithms to perform complex tasks and accelerate research.
A study in ACS Central Science shows that applying voltage to certain objects forms chemical bonds linking the objects together. Reversing the direction of electron flow separates the materials. This could help create biohybrid robots, improve biomedical implants and enable new battery technologies.
Of the various types of cancer screenings and procedures, colonoscopies are among the most effective in preventing cancer.
Scientists have identified a new target in ovarian cancer that is particularly vulnerable to chemotherapy. The discovery will allow researchers to better predict how this cancer will behave, particularly the most common and lethal, high-grade serous ovarian cancer (HGSOC). Ovarian cancer is one of the leading causes of cancer deaths among women.
Middle-age veterans who experienced concussions due to blasts from explosive devices may have biomarkers in their spinal fluid similar to people who develop Alzheimer’s disease, according to a new study published in the March 13, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Researchers from Rutgers Health and other institutions dispute claims that the maternal death rate in the United States has climbed steeply in the past two decades.
Women are more likely than men to get diagnosed with multiple sclerosis (MS), an incurable disease that affects the central nervous system.
The fertility of both female and male tsetse flies is affected by a single burst of hot weather, researchers at the University of Bristol and Stellenbosch University in South Africa have found.
Supporting kids with maths homework is a common afterschool activity. But beyond the basics, new curricula and teaching strategies are making it harder for parents to help and it’s taking a serious toll on children’s confidence and learning.
A collaborative study between a bariatric and transplant surgery team has introduced new hope for patients suffering from end-stage renal disease (ESRD) who are also struggling with obesity. The study authors explored the outcomes of metabolic and bariatric surgery in ESRD patients and whether the surgery can improve their eligibility for kidney transplants. The findings are published in the Journal of the American College of Surgeons (JACS).
Glucagon-like peptide-1 (GLP-1) agonists such as Ozempic® or Wegovy® (semaglutide), Saxenda® (liraglutide), or Zepbound™ (tirzepatide), have become increasingly popular in promoting weight loss.
For telescopes operating in the vacuum of space, or optical equipment in extreme environments, existing coatings are often insufficient. In the Journal of Vacuum Science & Technology Aresearchers in China turned to atomic layer deposition and developed an ultrablack thin-film coating for aerospace-grade magnesium alloys. The team used alternating layers of aluminum-doped titanium carbide and silicon nitride and together the materials prevent nearly all light from reflecting off the coated surface. The coating absorbs 99.3% of light while being durable enough to survive in harsh conditions.
Rosalind J. Wright, MD, MPH, appointed inaugural Dean for Public Health and Chair of the new Department of Public Health to spearhead a state-of-the-art curriculum in public health research, education, and practice that will systematically integrate with medicine, population health, global health, neurosciences, environmental medicine, data science and Artificial Intelligence (AI) disciplines.
Gait impairments often are prevalent in the early stages of cognitive decline. Researchers quantitatively compared straight walking and curved walking – a more natural yet complex activity – in healthy older adults and adults with mild cognitive impairment (MCI). A depth camera detected and tracked 25 joints of body movement and signals were processed to extract 50 gait markers. Intriguingly, curved walking illuminated notable disparities between the study groups.
A new analysis of 5.8 million Americans finds that earning a college degree is still a sound investment, although the rate of economic return varies across college majors and student demographics.
Age-related changes that cause the skin to stiffen and become less elastic may also contribute to higher rates of metastatic skin cancer in older people, according to research by investigators from the Johns Hopkins Kimmel Cancer Center.
Life on the land can be great, but it can also put a lot of pressure on romantic relationships. Now, rural health experts from the University of South Australia have launched a new online resource to help farmers build and maintain a healthy relationship with their partner.
The Portman lab at the Del Monte Institute for Neuroscience at the University of Rochester discovered that the male roundworms use pheromones and touch signals to determine the sex, age, nutritional health, and mating history of the hermaphrodites and show preference toward worms that have not previously mated with another male and are nutritionally healthy.
In states that relaxed firearm laws to allow openly carrying a loaded firearm in public without a permit, significantly more people died by firearms and suicide than in states without permitless open carry laws, according to study findings published in the Journal of the American College of Surgeons (JACS).
In the largest randomized clinical trial and first of its kind to date in the United States, a team led by investigators at Beth Israel Deaconess Medical Center (BIDMC) assessed the efficacy and safety of using a drug-coated balloon in patients undergoing coronary angioplasty.
Typically there is a gap nationally in higher education between the percentages of students who arrive at college expressing a desire to study science, technology, engineering, and math fields and those who stick with them. Statistics show that the fall-off is even higher among Black and Hispanic students. Bates College in Maine set out to change that.
Medicaid coverage has historically ended at 60 days postpartum, but according to new data, a significant number of maternal deaths are happening between 43 and 365 days postpartum.
Sun sensitivity and related skin conditions are often misunderstood. Foods, medications, and skincare products can trigger symptoms like itching, redness, blistering, or burning. One of the most common conditions is photocontact dermatitis, a skin reaction occurring when certain substances come into contact with skin that is exposed to the sun.
LGBTQ+ individuals have unique skin care needs, including concerns about sexually transmitted infections (STI), like HIV, as well as acne and hair growth and removal, especially relating to hormone replacement therapy.
U.S. veterans are at a higher risk of developing melanoma, one of the deadliest forms of skin cancer, likely due in part to the occupational hazards associated with active duty in countries near the equator where ultraviolet (UV) levels are higher.
