Maternal Programming During Pregnancy Induces Long-Term Postpartum Obesity

Tue, 2019-01-08 12:06

In a new study using a mouse model, researchers at University of California San Diego School of Medicine suggest that long-term postpartum weight gain may be due not so much to retained fat as to reprogramming of maternal energy metabolism.

With OK From FDA, UC San Diego Researchers Prepare to Launch Novel Phage Study

Tue, 2019-01-08 08:31

FDA approves first U.S. clinical trial of an intravenously administered bacteriophage-based therapy to treat resistant bacterial infections.

New CRISPR-based Technology Developed to Control Pests with Precision-guided Genetics

Tue, 2019-01-08 08:00

Using CRISPR, researchers developed a way to suppress insects, including those that ravage crops and transmit deadly diseases. The technology alters genes for sex determination and fertility. When eggs are introduced, only sterile males emerge, resulting in a low-cost method of controlling pests.

An Errant Editing Enzyme Promotes Tumor Suppressor Loss and Leukemia Propagation

Thu, 2019-01-03 08:46

UC San Diego researchers have found a stem cell enzyme copy edits more than 20 tumor types, providing new therapeutic target for preventing cancer cell resistance to chemotherapy and radiation.

UC San Diego Researchers Identify How Skin Ages, Loses Fat and Immunity

Wed, 2018-12-26 08:00

Some dermal fibroblasts can convert into fat cells that reside under the dermis, giving skin a youthful look and producing peptides that fight infections. University of California San Diego School of Medicine researchers and colleagues show how this happens and what causes it to stop as people age.

Hardware-Software Co-Design Approach Could Make Neural Networks Less Power Hungry

Wed, 2018-12-19 10:37

Engineers have developed a neuroinspired hardware-software co-design approach that could make neural network training more energy-efficient and faster. Their work could one day make it possible to train neural networks on low-power devices such as smartphones, laptops and embedded devices.

Serious Loneliness Spans the Adult Lifespan but there is a Silver Lining

Tue, 2018-12-18 10:00

Moderate to severe loneliness can persist across adult lifespans, but UC San Diego School of Medicine researchers found it is particularly acute in three age periods: late-20s, mid-50s and late-80s. Wisdom proved a protective factor.
