AI device identifies objects at the speed of light

AI device identifies objects at the speed of light
A team of UCLA electrical and computer engineers has created a physical artificial neural network — a device modelled on how the human brain works — that can analyse large volumes of data and identify objects at the actual speed of light. The device was created using a 3D printer at the UCLA Samueli School of Engineering.

Stimulator bypasses spine injury and helps patients move hands

Stimulator bypasses spine injury and helps patients move hands
Doctors at Ronald Reagan UCLA Medical Center have implanted a spinal stimulator that is showing early promise in returning hand strength and movement to a California man who broke his neck in a dirt-biking accident five years ago. Brian Gomez, 28, became one of the world's first patients to undergo surgery for the experimental device in June 2016. UCLA scientists positioned the 32-electrode stimulator below the site of Gomez's spinal-cord injury, near the C-5 vertebrae in the middle of his neck.

Stem cells grown into 3D lung-in-a-dish

Stem cells grown into 3D lung-in-a-dish
By coating tiny gel beads with lung-derived stem cells and then allowing them to self-assemble into the shapes of the air sacs found in human lungs, researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have succeeded in creating 3D lung "organoids." The laboratory-grown lung-like tissue can be used to study diseases including idiopathic pulmonary fibrosis, which has traditionally been difficult to study using conventional methods.

Method speeds up detection of infectious diseases

Method speeds up detection of infectious diseases
A team of UCLA researchers has found a way to speed and simplify the detection of proteins in blood and plasma opening up the potential for diagnosing the early presence of infectious diseases or cancer during a doctor's office visit. The test takes about 10 minutes as opposed to two to four hours for current state-of-the-art tests. The approach overcame several key challenges in detecting proteins that are biomarkers of disease.

Ultrasound jump-starts man's brain after coma

Ultrasound jump-starts man's brain after coma
A 25-year-old man recovering from a coma has made remarkable progress following a treatment at UCLA to jump-start his brain using ultrasound. The technique uses sonic stimulation to excite the neurons in the thalamus, an egg-shaped structure that serves as the brain's central hub for processing information. "It's almost as if we were jump-starting the neurons back into function," said Martin Monti, the study's lead author and a UCLA associate professor of psychology and neurosurgery.

Creating specialised cells more efficiently

Creating specialised cells more efficiently
Researchers at the UCLA Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have discovered that a metabolic molecule called alpha-ketoglutarate helps pluripotent stem cells mature early in the process of becoming adult organs and tissues. The findings, published online in the journal Cell Metabolism, could be valuable for scientists working toward stem cell–based therapies for a wide range of diseases.

Biomarkers give cancer patients better survival estimates

Biomarkers give cancer patients better survival estimates
A method developed by UCLA scientists uses data about patients' genetic sequences to produce more reliable projections for survival time and how they might respond to possible treatments. The technique is an innovative way of using biomedical big data—which gleans patterns and trends from massive amounts of patient information—to achieve precision medicine—giving doctors the ability to better tailor their care for each individual patient.

AI helps detect cancer cells

AI helps detect cancer cells
Scientists at the California NanoSystems Institute at UCLA have developed a new technique for identifying cancer cells in blood samples faster and more accurately than the current standard methods. In one common approach to testing for cancer, doctors add biochemicals to blood samples. Those biochemicals attach biological "labels" to the cancer cells, and those labels enable instruments to detect and identify them.

Platform optimises drug dose combinations

Platform optimises drug dose combinations
  For decades, doctors and scientists have predicted that personalised medicine—tailoring drug doses and combinations to people's specific diseases and body chemistry—would be the future of health care. A team of UCLA bioengineers and surgeons has taken a major step toward that reality.

Robots are fully capable of accomplishing a variety of tasks

Robots are fully capable of accomplishing a variety of tasks
They are all shapes and sizes, with all numbers of legs. They can put out fires on ships, shimmy up construction sites to do dangerous inspections, safely traverse battlefields and enter power plants to plug radiation leaks. Oh, and they play soccer, too. One tiny one even break-dances. These are just some of the products of the endlessly creative mind of UCLA's Dennis Hong, director of the legendary RoMeLa (Robotics and Mechanisms Laboratory), and his intrepid band of robot-loving graduate and undergraduate students.

Chemotherapy drug directed to tumour site through nanoparticles

The overall five-year survival rate for people with pancreatic cancer is just 6%, and there is an urgent need for new treatment options. More than 80% of pancreatic cancer diagnoses occur too late for surgery, making chemotherapy the only possible treatment. Scientists from the California NanoSystems Institute at UCLA and UCLA's Jonsson Comprehensive Cancer Center have developed a delivery system for one chemotherapy drug that greatly reduces the occurrence of serious side effects while enhancing the drug's effectiveness against pancreatic cancer.

Open source code for powerful image detection algorithm

Open source code for powerful image detection algorithm
A UCLA Engineering research group has made public the computer code for an algorithm that helps computers process images at high speeds and “see” them in ways that human eyes cannot. The researchers say the code could eventually be used in face, fingerprint and iris recognition for high-tech security, as well as in self-driving cars’ navigation systems or for inspecting industrial products.

3D printed mobile device provides diagnostic accuracy

3D printed mobile device provides diagnostic accuracy
A team of researchers from the California NanoSystems Institute at UCLA has developed a mobile phone-based device that can read ELISA plates in the field with the same level of accuracy as the large machines normally found in clinical laboratories. ELISA, or Enzyme-Linked ImmunoSorbant Assay, is a diagnostic tool that identifies antigens such as viruses and bacteria in blood samples.
