The Sandia chuck uses a thin layer of helium gas to cool silicon wafers, utilizing electrostatic attraction to seal the wafer to a bottom plate. The device features a patterned silicon wafer with tiny islands that support the wafer and allow for rapid clamping and release.
Anthropologist David Price warns that world population's dire Malthusian 'correction' is inevitable due to finite resources. Despite progress in measures to prevent overpopulation, the stakes are higher now than ever, with proportionately more loss expected.
Researchers at Memorial Sloan-Kettering Cancer Center found that growth factors, known for controlling immune cell production, also increase the ability of immune cells to take up vitamin C. This discovery sheds light on the connection between vitamin C and the immune system, showing how growth factors can boost immune function.
A nationwide study found a significant decline in HIV-related deaths and opportunistic infections from 1994 to mid-1997, largely due to the use of combination antiretroviral therapy including protease inhibitors. Prescription rates for combination therapy increased dramatically during this period.
A University at Buffalo study found that women typically travel six miles to shop, while men travel an average of 6.5 miles, highlighting the impact of time constraints on shopping decisions. The research suggests that retailers should consider the limitations faced by female customers when developing retail establishments.
Scientists have identified peptides substance P and neurokinin A as key components in the body's pain responses. The study suggests that these peptides work together to produce moderate-to-severe pain, offering a potential target for new pain treatments.
The Fiber and Electro-Optics Research Center at Virginia Tech has received a $9.6 million grant from the Naval Research Laboratory to develop new technologies in microelectronics and nanostructured materials. Researchers aim to create more efficient devices with improved electronic, optical, mechanical properties.
A UCSF research team has made a striking discovery that mild and intense pain are biologically distinct, involving different neurotransmitters. This knowledge could lead to the development of new drugs targeting these molecules to provide effective pain relief with lower morphine doses.
Researchers found that lower precombat and current intelligence were associated with PTSD symptoms among Vietnam veterans. Lower intelligence may lead to increased feelings of overwhelm and helplessness, increasing the risk for chronic PTSD.
The all-terrain wheelchair is designed to cross potholes, hobble over obstacles, and cruise along sandy beaches. It features powered rear wheels and robotic arms that anchor the chair like crutches or ski poles.
Research highlights girls' increased relational victimization, leading to social anxiety, loneliness, and self-restraint issues. The study underscores the importance of studying relational victimization for girls' mental health.
A NASA scientist has found a new puzzle in the sky, an X-ray pulsar that appears to burst twice every 'year' rather than once. Colleen Wilson discovered GRO J2058+42, which has no visible component and exhibits unusual behavior, suggesting it may be a binary star system with a type Be star and a neutron star in a lopsided orbit.
The study reveals human beta-tryptase is a ring-like tetramer with active sites facing a central pore. Its unique architecture explains many of its distinct biochemical properties and will facilitate understanding of its role in health and disease.
Scientists at Duke University discovered a genetic switch that governs prostate cancer progression. The switch controls the production of FGF-R2 receptors, which can lead to
A recent study found that brain-enriched hyaluronan binding protein (BEHAB) is a key factor in brain cancer cells' ability to invade healthy tissue. Researchers hope to develop therapies that block BEHAB's function or reduce its production, potentially slowing tumor progression.
