Researchers have found nearly complete fossil cranium and skullcap in Dmanisi, Georgia, dating back to 1.7 million years ago. The discovery suggests early human species may have left Africa earlier than previously thought, with the possibility that they were driven by appetite for more protein.
A new Penn State study reveals that restrictive feeding practices can pass eating problems from mother to daughter as early as five years old, increasing the risk of childhood overweight. Mothers who control their own weight tend to use more restrictive feeding practices, which can actually promote patterns of intake influenced by pala...
A molecular-level malfunction in patients with heart failure can be repaired with existing treatments, suggesting a new approach to treating the root cause of the disease. The research reveals that a malfunctioning calcium channel is responsible for the defect, and beta blockers may prevent or reverse its development.
Researchers discovered that low nitric oxide levels in mouse newborns with hypoplastic lungs hinder the proper development of blood vessels, leading to persistent pulmonary hypertension and respiratory distress. The study aims to identify genes affecting lung development and function.
The Chandra X-ray Observatory has imaged the full impact of Supernova 1987A for the first time, revealing a shock wave smashing into the outer parts of a ring at 4,500 km/s. The gas behind the shock wave has a temperature of ten million degrees Celsius.
A new study reveals that even in countries with universal healthcare, there are significant restrictions on prescription drug accessibility for the elderly. The research found that countries like Australia, Canada, and the UK have varying levels of outpatient pharmaceutical plans, but often come with high costs.
The Fred Hutchinson Cancer Research Center is proud to announce that five of its researchers have been selected as Howard Hughes Medical Institute (HHMI) investigators. Drs. David Baker, Philip Green, and Michael Shadlen from the University of Washington, and Drs. Leonid Kruglyak and Cecilia Moens from the Fred Hutchinson Cancer Resear...
A new Harvard Medical School study found that only 14% of patients treated for three common mental illnesses received adequate care. African-Americans and those without insurance coverage are less likely to receive satisfactory mental health care.
David Wetzel's new technique uses infrared microspectroscopy to analyze small specimens without grinding or staining, revealing localized chemical content and spatial resolution. The technology has increasing applications in biological and other research, including rare blood disorders and hit-and-run cases.
A study published in Nature found that individuals with aphasia, who experience language loss after a stroke or brain damage, possess an exceptional ability to detect deception. They were able to identify lies cued by facial expressions alone with high accuracy, outperforming other groups.
The JDF Center aims to develop new gene therapy techniques to increase islet cell supply for transplantation and protect transplanted cells from immune system attack. The center will focus on making islet cell transplants viable for young patients with Type 1 Diabetes.
Research suggests that high levels of environmental endotoxin in homes with sensitive children may drive the immune system to produce cytokines that inhibit processes leading to asthma. Conversely, homes with children who are not sensitized to common allergens have significantly higher endotoxin levels.
Researchers found that a synthetic protein resembling the herpes simplex virus mimics beta-amyloid, a toxic agent in Alzheimer's patients. This connection could lead to the development of vaccines or drugs to prevent or treat Alzheimer's disease.
A study published in The New England Journal of Medicine found that a high-fiber diet can lower blood glucose levels and decrease insulin levels in patients with type II diabetes. Patients who consumed 50 grams of fiber per day showed a 10% reduction in glucose levels, compared to the recommended 24 grams of fiber per day.
