Scientists from UCSD's Divisions of Biology and Physical Sciences have observed the formation of permanent nerve connections that store short- and long-term memories. By visualizing the rods and filaments of actin, they discovered that these changes occur after repeated stimulation, mimicking human memory consolidation.
A new UCSF study found that many cancer patients are not taking around-the-clock and as-needed pain medicines as prescribed by their physicians. This results in inadequate pain relief, with only 29.2% of patients receiving both long-acting and short-acting opioids.
The survey found rising numbers of heterosexual partners, concurrent relationships, and STI cases, with women experiencing more significant increases. Early age at first intercourse was linked to higher pregnancy rates and lower condom use.
A randomized trial of 17,000 patients from 46 countries shows that bivalirudin reduces the risk of recurrent heart attack by 30% compared to heparin. The study also found no significant increase in severe bleeding or intracerebral bleeding in patients given bivalirudin.
The Gulf Coast Consortia is a new research and education initiative funded by a $3.5 million grant from the W. M. Keck Foundation. The consortium brings together six public and private institutions to address the national shortage of researchers and promote inter-institutional collaboration.
Researchers have developed a new method for studying viral entry, which reveals that key steps occur much faster than previously believed. The study found that viruses can penetrate cells within minutes, using the cell's own transportation system to reach the nucleus.
Researchers have developed a way to synthesize ciguatoxin, the toxin responsible for seafood poisoning, which will enable scientists to better understand its effects on humans and prepare toxin-fighting antibodies. The breakthrough could lead to more efficient methods for detecting infected fish before they reach the market.
The NIAID's new center will support research on three to 10 important pathogens over the next three years. It will develop new technologies for analyzing gene function, train researchers, and provide resources for the scientific community. The center aims to better understand individual genes and proteins to develop targeted treatments.
The Wildlife Conservation Society will use the grant to manage and protect key areas with intact ecosystems, such as the Ndoki-Likouala rain forest in the Republic of Congo and the Greater Yellowstone Ecosystem. WCS's Living Landscapes approach aims to balance human needs with wildlife conservation.
A team of researchers at Stanford Medicine has discovered a new gene family, the Tim family, that plays a crucial role in asthma development. The link between this gene family and the hepatitis A virus may help explain why asthma rates have increased where hepatitis A infection rates have dropped.
Researchers have discovered long-term potentiation, a brain process that strengthens connections and promotes memory. This process involves the rapid relocation of receptors in synapses, leading to increased synaptic transmission and potentially explaining why memory can falter.
Researchers at USC/Norris Comprehensive Cancer Center developed a test that analyzes tumor tissue to predict response to oxaliplatin and 5-FU chemotherapy. Patients with low ERCC1 and TS expression survived longer than those with high levels, indicating the potential for more effective treatment customization.
The Saint Louis University School of Public Health has launched High 5-Kids, a four-year program aiming to educate parents on normal childhood eating patterns. The initiative seeks to encourage healthy eating habits among preschool children, aged 3-5 years, and promote a balanced diet to prevent obesity and cancer.
A study by Stanford University urologist James D. Brooks confirms a direct connection between selenium and reduced risk of prostate cancer, particularly among older men with lower blood levels of the essential mineral.
A Dutch study found that long-term ecstasy use is associated with brain-cell damage in women, particularly in serotonin neurons. The effects of moderate ecstasy use on these neurons have not been studied, highlighting the need for further research.
UCSD researchers have discovered a natural regulatory protein, RGS-PX1, with dual roles in regulating cellular functions. The protein modulates both cell signaling and membrane trafficking, offering new avenues for disease research and potential targets for developing drugs to treat heart failure, hormone imbalances, and cancer.
The study found that internet users watch significantly less television than non-internet users, with a decline of 4.5 hours per week. Parents are increasingly denying access to the internet as punishment, and young people are more likely to prefer online interactions over in-person ones.
A 1998 study on childhood sexual abuse has been widely discredited by Stanford researchers, citing flawed research methods and misleading data. The authors re-examined the data and found significant problems with the initial analysis, including biased samples and misreporting of original data.
A genetic vaccine developed by the University of Nebraska Medical Center has shown promising results in mice studies, combining DNA and adenovirus to deliver a tumor suppressor factor. The vaccine improved survival rates up to 40% in mice with metastatic breast cancer.
Researchers have detected a rigid material within the fluid outer core, with implications for Earth's magnetic field and rotation axis. The discovery was made using advanced seismic tomography techniques.
Researchers developed a new fluorescence resonance energy transfer technique to track changes in protein structure, enabling precise correlation with functions. The method shows potential for understanding issues like biocompatibility of medical implants, blood clotting processes, and cancer metastasis.
A recent study suggests that predators play a key role in maintaining a balanced ecosystem. The research, conducted on small islands with no natural predators, found that the absence of top-down regulation led to an explosion in plant-eating animals and herbivores, resulting in a collapse of vegetation.
Researchers at Harvard Medical School have identified nearly all the genes responsible for vision in mice, which could lead to new methods for preserving and restoring vision. The discovery provides a genetic data base that can help identify genes mutated in inherited diseases such as retinitis pigmentosa and cone-rod dystrophy.
A recent Amnesty International report highlights the torture and ill-treatment of lesbian, gay, bisexual, and transgender people. Health experts argue that healthcare providers have a moral responsibility to uphold the rights and dignity of LGBTQ+ individuals.
Scientists have created a novel crystal lattice with unprecedented optical properties, enabling the manipulation of light at higher frequencies. This breakthrough has potential applications in telecommunications and drug separation.
A team of scientists led by Joanne Chory and Detlef Weigel studied the natural variation in light sensitivity across different Arabidopsis varieties. They found that strains from lower latitudes were less sensitive to light, and that specific genetic mutations affected the molecule's ability to transmit signals. The study sheds light o...
Scientists have found that fully protected marine reserves can replenish nearby fisheries, increasing catches and producing bigger fish. In Florida, recreational fishers are catching record-breaking sizes of black drum, red drum, and spotted sea trout in waters adjacent to the US's oldest marine reserve.
Researchers at Stanford University studied the Caribbean spiny lobster's ability to track odors using its antennules, finding that rapid downstroke allows high-resolution information capture while slow upstroke provides time for analysis. The findings could help develop robots for plume tracing underwater.
Researchers have discovered two independent pathways for mRNA export from the nucleus, revealing the role of adapter proteins in regulating this process. The study used cell-permeable peptides to selectively block the action of these proteins, demonstrating their importance in transporting mRNAs for early response genes.
