Researchers have identified UBA1 enzyme as key mediator for immune response to tumors, inhibiting its activity increases T-cell recruitment and lowers tumor resistance. Pairing UBA1 inhibitors with immune checkpoint blockade therapies may make immunotherapy more effective for patients with 'cold' tumors.
A team of researchers discovered a class of materials that mimic the behavior of axons by spontaneously amplifying electrical pulses. These materials can harness internal instabilities to create spiking behavior and amplify signals, potentially leading to more efficient computing and artificial intelligence.
Researchers have identified a potent and unique way to kill drug-resistant bacteria using a repurposed compound called LEI-800. The compound targets the bacterial enzyme DNA gyrase, which is essential for bacterial growth and has not been targeted by existing antibiotics.
The CCR4-NOT complex plays a crucial role in regulating RNA metabolism and stress response in C. elegans, compromising stress resistance and decreasing lifespan when depleted of subunits. This study highlights an important new role for the CCR4-NOT complex in normal aging and longevity.
Researchers developed a reliable and reproducible real-time live tissue sensitivity assay (RT-LTSA) using fresh tumor samples to predict patients' clinical response to chemotherapy. The study showed improved disease-free survival and reduced recurrence rates in patients who received RT-LTSA sensitive adjuvant regimens.
Researchers found a strong positive correlation between BRD4 overexpression and chemoresistance in ovarian cancer. The study demonstrated that BRD4-L and BRD4-S isoforms play a role in promoting chemotherapy resistance in high-grade serous ovarian carcinoma.
A new study reveals that preoperative hydroxyprogesterone administration can improve disease-free and overall survival in patients with node-positive breast cancer by modulating cellular stress response and negative regulation of inflammation. Non-coding RNAs, such as DSCAM-AS1, play a regulatory role in this process.
A new study from the University of Kansas found that rural transgender youths use resilience and resistance strategies to cope with discrimination and hostility. These strategies include affirming themselves, maintaining authenticity, resisting oppressive narratives, and taking action to defend their rights.
Researchers have discovered that organic LEDs (OLEDs) exhibit regions of reduced brightness known as 'switched-back' effects, despite increased applied current. This phenomenon is attributed to negative differential resistance induced by nonlinear electrothermal feedback, which can lead to unstable operation and device breakdown.
Researchers at the University of Alberta have discovered the precise atomic structure giving rise to negative differential resistance. This breakthrough enables practical applications in everyday electronics like phones and computers, promising faster, cheaper, and smaller devices.
Researchers at Georgia State University discovered that negative resistivity can produce a positive resistance in GaAs/AlGaAs semiconductor devices under the influence of a magnetic field. The sign reversal in the Hall effect also occurs.
A recent study found that tomato plants artificially stimulated with chemical jasmonic acid attract parasitic wasps, which kill twice as many caterpillars on treated plants. This natural defense mechanism can be used to develop environmentally friendly agricultural pest control methods.
