Colorado study suggests new strategies against bone metastases from prostate cancer

University of Colorado Cancer Center study suggests a new approach, or, possibly two new approaches against prostate cancer bone metastases: While targeted therapies and anti-cancer immunotherapies have not been especially successful against primary prostate cancers, the study suggests that both these approaches may be effective against the bone metastases that grow from primary prostate cancers,...

Deep learning identifies molecular patterns of cancer

An artificial intelligence platform developed at the Max Delbrück Center for Molecular Medicine (MDC) can analyze genomic data extremely quickly, picking out key patterns to classify different types of colorectal tumors and improve the drug discovery process. The deeper analysis shows some colorectal subtypes need to be reclassified.

Developing a new AI breast cancer diagnostic tool

Scientists are developing a new way to identify the unique chemical 'fingerprints' for different types of breast cancers.These new chemical footprints will be used to train AI software -- creating a new tool for rapid and accurate diagnosis of breast cancers.

Discovery of an unusual protein

Scientists from Bremen discover an unusual protein playing a significant role in the Earth's nitrogen cycle. The novel heme-containing cytochrome is involved in the anammox process, which is responsible for producing half of the dinitrogen gas in the atmosphere and important in greenhouse gas regulation.

Earthquake risk perception: A picture is worth a thousand stats

Realistic images can be more effective than statistics for persuading people to support seismic upgrades to schools, UBC research suggests. Seismic engineers and psychologists teamed up with a visual artist to create an image of a Vancouver school after a major earthquake. When given the opportunity to sign a petition in support of accelerating seismic upgrading, people who had seen the image were...

Genomic gymnastics help sorghum plant survive drought

A new study provides the first detailed look at how the sorghum plant exercises exquisite control over its genome -- switching some genes on and some genes off at the first sign of water scarcity, and again when water returns -- to survive when its surroundings turn harsh and arid.

Helping machines perceive some laws of physics

MIT researchers have designed a model that demonstrates an understanding of some basic "intuitive physics" about how objects should behave. The model could be used to help build smarter artificial intelligence and, in turn, provide information to help scientists understand infant cognition.

Immunology -- Activation by breakdown

Ludwig-Maximilians-Universitaet (LMU) in Munich researchers report that a central component of the innate immune response is activated by two short RNAs which are produced by site-specific cleavage of a precursor RNA molecule -- and both derivatives are generated by the same enzyme.

Machine learning that works like a dream

University of Tsukuba researchers developed a machine learning algorithm that classifies the sleep stages of mice with record accuracy. This work may be used to greatly enhance the field of sleep research.

Major epilepsy study offers much-needed answers on 3 lifesaving seizure drugs

There are effective treatments to stop life-threatening epilepsy seizures when the initial treatment has failed, a sweeping new study reveals. The study offers important answers about three such emergency drugs that are used to treat prolonged seizures, known as status epilepticus, even though physicians have had little understanding of the drugs' effectiveness. Until now, there has been no clear...

Mental health information in rural areas is best delivered face-to-face, study shows

Mental health is a concern in rural areas, as farmers cope with stress and uncertainty due to economic and environmental conditions. Often, there are no mental health providers in the local community. Public health programs can help, but what are the best ways to reach farm populations with those programs? That's the topic of a new study conducted by a University of Illinois researcher.

Micro implants could restore standing and walking

Researchers at the University of Alberta are focused on restoring lower-body function after severe spinal injuries using a tiny spinal implant. In new research, the team showcases a map to identify which parts of the spinal cord trigger the hip, knees, ankles and toes, and the areas that put movements together.

Model probes possible treatments for neonatal infection, a common cause of infant death

Extremely premature infants are at risk for life-threatening infections called late-onset sepsis, or LOS, that spread into their bodies from the intestine. Researchers now report a new model for LOS, and they show that disrupting the normal maturation of gut microbes can make newborn mouse pups highly susceptible to LOS. Furthermore, they found they could prevent the deadly infection by giving the...

Molecular vibrations lead to high performance laser

Researchers at the USC Viterbi School of Engineering have discovered a new phenomenon and are applying it to make a laser with over 40% efficiency-nearly 10 times higher than other similar lasers. The laser itself is made from a single layer of molecules anchored to a glass ring on a silicon wafer. It has improved power consumption and is fabricated from more sustainable materials than previous...

New treatment for brain tumors uses electrospun fiber

University of Cincinnati professor Andrew Steckl, working with researchers from Johns Hopkins University, developed a new treatment for glioblastoma multiforme, an aggressive form of brain cancer. Steckl's Nanoelectronics Laboratory applied an industrial fabrication process called coaxial electrospinning to form drug-containing membranes.
