| Switching from Western diet to a balanced diet may reduce skin, joint inflammation Posted: 22 Jun 2021 01:10 PM PDT Diet rich in sugar and fat leads to disruption in the gut's microbial culture and contributes to inflammatory skin diseases such as psoriasis. Research shows that switching to a more balanced diet restores the gut's health and suppresses inflammation. |
| In many cases, MS starts long before the diagnosis Posted: 22 Jun 2021 12:43 PM PDT Years before they are diagnosed, persons with multiple sclerosis (MS) make significantly more visits to doctors and hospitals than others. Specialists have recently discussed whether this might represent a preliminary phase of MS - known as a prodrome. A new study suggests that, in many cases, the complaints may relate to unrecognized early clinical MS events. |
| It's true: Stress does turn hair gray (and it's reversible) Posted: 22 Jun 2021 12:43 PM PDT A new study offers quantitative evidence linking psychological stress to graying hair in people. |
| Self-reported declines in cognition may be linked to changes in brain connectivity Posted: 22 Jun 2021 10:23 AM PDT A research team recently published the results of a three-year study of cognitive changes in older adults who complained that their cognitive ability was worsening though clinical assessments showed no impairments. The MRI studies showed significant changes in functional connectivity in two areas of the brain. |
| How pancreatic cancer cells dodge drug treatments Posted: 22 Jun 2021 10:23 AM PDT Pancreatic cancer cells typically rely on a mutant version of the KRAS protein to proliferate. These cancer cells can also survive losing KRAS by activating alternative growth pathways. Scientists discovered a new interaction between mutant KRAS and a protein complex called RSK1/NF1 that may be the source of this adaptive resistance. |
| Scientists identify combination of biological markers associated with severe dengue Posted: 22 Jun 2021 09:53 AM PDT Researchers have identified a combination of biological markers in patients with dengue that could predict whether they go on to develop moderate to severe disease. |
| Personality traits relate to being a morning or evening person Posted: 22 Jun 2021 09:33 AM PDT The link between the different hierarchies of personality, sleep patterns and even genetics has now been discovered. |
| Inherited risk of early-onset cancer is higher among minority families Posted: 22 Jun 2021 09:33 AM PDT A new study shows inherited risk of early-onset cancer is significantly higher among Latino and African American families for solid tumors, and Asian/Pacific Islander families for blood-based cancers, compared to non-Latino white families in California. Researchers used California population-based health registries to evaluate the relative cancer risk among first-degree relatives of patients diagnosed with cancer by the age of 26. This study demonstrates the need for increased scrutiny on familial cancer clustering in minority populations. |
| Boost for mouse genetic analysis Posted: 22 Jun 2021 09:33 AM PDT To understand what role an individual gene plays, biologists have, for 100 years, been using a trick of nature: While in principle, the genome in all cells of an organism is the same, mutations arise in individual cells. These mutations differentiate a cell from its neighbors, forming a 'genetic mosaic.' Now, researchers have advanced genetic mosaic analysis, making almost all genes in the mouse genome accessible to single-cell genetic mosaic analysis. |
| Sports: Men and women react differently to a missing audience Posted: 22 Jun 2021 09:33 AM PDT Without an audience, men run slower and women faster: The lack of spectators during the coronavirus pandemic appears to have had a noticeable effect on the performance of athletes at the 2020 Biathlon World Cup, a new study shows. According to the new analysis, women also performed better in complex tasks, such as shooting, when an audience was present while men did not. |
| Venomous caterpillar has strange biology Posted: 22 Jun 2021 09:33 AM PDT The venom of a caterpillar, native to South East Queensland, shows promise for use in medicines and pest control, researchers say. |
| Secretin hormone induces satiation by activating brown fat Posted: 22 Jun 2021 09:32 AM PDT Researchers have discovered a new mechanism controlling satiation. According to the recently published study, the hormone secretin induces satiation by activating brown adipose tissue. |
| AR can improve the lives of older adults, so why are apps designed mainly for youngsters? Posted: 22 Jun 2021 09:32 AM PDT Older people affected by memory loss have much to gain from AR technology, yet a study exploring the use of augmented reality to support older adults at home finds the user interface is sometimes confusing for those aged 50+. |
| Childhood trauma can make people like morphine more Posted: 22 Jun 2021 09:32 AM PDT People who have experienced childhood trauma get a more pleasurable 'high' from morphine, new research suggests. |
| Open learning spaces do not increase children's physical activity Posted: 22 Jun 2021 09:32 AM PDT According to a recent study, open learning spaces are not directly associated with the physical activity of students in grades 3 and 5, even though more breaks from sedentary time were observed in open learning spaces compared to conventional classrooms. |
| 'Urban green space affects citizens' happiness' Posted: 22 Jun 2021 06:53 AM PDT A recent study revealed that as a city becomes more economically developed, its citizens' happiness becomes more directly related to the area of urban green space. |
| Engineering nanobodies as lifesavers when SARS-CoV-2 variants attack Posted: 22 Jun 2021 06:53 AM PDT Scientists are pursuing a new strategy in the protracted fight against the SARS-CoV-2 virus by engineering nanobodies that can neutralize virus variants in two different ways. |
| Cancer immunotherapy may self-limit its efficacy Posted: 22 Jun 2021 06:53 AM PDT Cancer immunotherapy involving drugs that inhibit CTLA-4 also activates an unwanted response that may self-limit its efficacy in fighting tumors, according to a new study. |
| Study shows brain differences in interpreting physical signals in mental health disorders Posted: 22 Jun 2021 06:16 AM PDT Researchers have shown why people with mental health disorders, including anorexia and panic disorders, experience physical signals differently. |
| Lead from leaded petrol persists in London air despite '90s ban Posted: 21 Jun 2021 01:05 PM PDT Lead levels in London's atmosphere have dropped drastically since lead additives in petrol were phased out, and currently meet UK air quality targets. However despite this drop, airborne particles in London are still highly lead-enriched compared to natural background levels, according to new research. |
| New research finds GCSE results linked to child's enjoyment of school aged six Posted: 21 Jun 2021 09:37 AM PDT A child's enjoyment of school at six years old is linked to their General Certificate of Secondary Education (GCSE) results aged 16, according to new research. |
