Blood biomarkers may allow easier detection, confirmation of concussions

Posted: 20 Apr 2018 02:06 PM PDT

Researchers have found that specific small molecules in blood plasma may be useful in determining whether someone has sustained a mild traumatic brain injury (mTBI), commonly known as a concussion.

When there's an audience, people's performance improves

Posted: 20 Apr 2018 09:29 AM PDT

Often people think performing in front of others will make them mess up, but a new study found the opposite: being watched makes people do better.

Remote-control shoots laser at nano-gold to turn on cancer-killing immune cells

Posted: 20 Apr 2018 09:29 AM PDT

Cancer immune cell therapy has made headlines with astounding successes like saving former US President Jimmy Carter from brain cancer. But immunotherapy has also had many tragic flops. Researchers working to optimize the innovative treatment have implanted a genetic switch that activates T-cells when they are inside of tumors. Remote-control light waves resembling those used in a TV remote combine with gold nanorods to flip the switch.

Rare earth magnet recycling is a grind -- this new process takes a simpler approach

Posted: 20 Apr 2018 09:29 AM PDT

A new recycling process turns discarded hard disk drive magnets into new magnet material in a few steps, and tackles both the economic and environmental issues typically associated with mining e-waste for valuable materials.

Treatment of cancer could become possible with adenovirus

Posted: 20 Apr 2018 09:28 AM PDT

Researchers have shown that adenovirus binds to a specific type of carbohydrate that is overexpressed on certain types of cancer cells. The discovery opens up new opportunities for the development of virus-based cancer therapy.

Soil metals linked with cancer mortality

Posted: 20 Apr 2018 09:28 AM PDT

Epidemiologists and geologists have found associations between esophageal cancer and soils where lead is abundant, lung cancer and terrains with increased copper content, brain tumor with areas rich in arsenic, and bladder cancer with high cadmium levels. These statistical links do not indicate that there is a cause-effect relationship between soil type and cancer, but they suggest that the influence of metals from the earth's surface on the geographical distribution of tumors should be analyzed.

Structured light and nanomaterials open new ways to tailor light at the nanoscale

Posted: 20 Apr 2018 09:28 AM PDT

New research has shown that carefully structured light and matching arrangements of metal nanostructures can be combined to alter the properties of the generated light at the nanometer scale. The teams have shown that the efficiency of nonlinear optical fields generated from the oligomers is strongly influenced by how the constituents of the oligomer constituents are illuminated by structured light.

New DNA screening reveals whose blood the vampire bat is drinking

Posted: 20 Apr 2018 09:28 AM PDT

The vampire bat prefers to feed on domestic animals such as cows and pigs. When it does so, there is a risk of transmission of pathogens. Now, a new study describes a new DNA method to efficiently screen many vampire bat blood meal and fecal samples with a high success rate and thereby determine which animals the vampire bats have fed on blood from.

Biomarkers for irritable bowel syndrome

Posted: 20 Apr 2018 09:28 AM PDT

Little is still known about the exact causes of irritable bowel syndrome. An international team has provided initial clues about the organic triggers of the disease, which affects an estimated one out of six people.

Lupus treatment generates positive results in Phase III clinical trial

Posted: 20 Apr 2018 09:28 AM PDT

New research indicates that belimumab, a monoclonal antibody therapy that targets a component of the immune system, provides considerable benefits to patients with systemic lupus erythematosus (SLE), a predominately female, chronic inflammatory disease that can affect virtually any organ.

Medical chemists discover peptic ulcer treatment metallodrug effective in 'taming' superbugs

Posted: 20 Apr 2018 09:28 AM PDT

A novel solution to antimicrobial resistance -- medical chemists discover peptic ulcer treatment metallodrug effective in 'taming' superbugs.

Trees are not as 'sound asleep' as you may think

Posted: 20 Apr 2018 09:28 AM PDT

High-precision three-dimensional surveying of 21 different species of trees has revealed a yet unknown cycle of subtle canopy movement during the night. The 'sleep cycles' differed from one species to another. Detection of anomalies in overnight movement could become a future diagnostic tool to reveal stress or disease in crops.

Graphene sets a new record on squeezing light to one atom

Posted: 20 Apr 2018 09:28 AM PDT

Researchers reach the ultimate level of light confinement -- the space of one atom. This will pave the way to ultra-small optical switches, detectors and sensors.

Bottlenose dolphins recorded for the first time in Canadian Pacific waters

Posted: 19 Apr 2018 08:38 PM PDT

A large group of common bottlenose dolphins (Tursiops truncatus) have been spotted in Canadian Pacific waters -- the first confirmed occurrence of the species in this area.

A complete cell atlas and lineage tree of the immortal flatworm

Posted: 19 Apr 2018 11:15 AM PDT

From one stem cell to many differentiated body cells: Scientists have now published a comprehensive lineage tree of a whole adult animal. This was made possible by a combination of RNA and computational technologies.

Chip-based blood test for multiple myeloma could make bone biopsies a relic of the past

Posted: 19 Apr 2018 11:15 AM PDT

A new research effort has resulted in a low-cost, reliable blood test that uses a small plastic chip about the size of a credit card that can deliver the same diagnostic information as a bone biopsy -- but using a simple blood draw instead.

Age affects how we predict and respond to stress at home

Posted: 19 Apr 2018 10:09 AM PDT

A recent study finds that older adults are better than younger adults at anticipating stressful events at home -- but older adults are not as good at using those predictions to reduce the adverse impacts of the stress.

Small changes in rainforests cause big damage to fish ecosystems

Posted: 19 Apr 2018 10:09 AM PDT

Using lasers, researchers have connected, arranged and merged artificial cells, paving the way for networks of artificial cells acting as tissues.

'Rip Van Winkle' plants hide underground for up to 20 years

Posted: 19 Apr 2018 10:09 AM PDT

Scores of plant species are capable of living dormant under the soil for up to 20 years, enabling them to survive through difficult times, a new study has found.

Cancer: Tumor transition states

Posted: 19 Apr 2018 07:02 AM PDT

Researchers define for the first time the tumor transition states occurring during cancer progression and identify the tumor cell populations responsible for metastasis.
