| How Arctic-alpine plants respond to global warming Posted: 12 Aug 2021 11:51 AM PDT Researchers have studied how two characteristic Arctic-alpine plant species respond to global warming. They did this by analyzing almost 500 million of their own readings from the mountainous region of Norway. The analyses show that potential consequences of climate change are extremely dependent on the specific location of the plants and that deciduous species in particular will benefit from warming. The result would be a further increase in the trend toward greening of the Arctic-alpine regions. |
| Genetic enigma solved: Inheritance of coat color patterns in dogs Posted: 12 Aug 2021 11:51 AM PDT Scientists have unraveled the enigma of inheritance of coat color patterns in dogs. The researchers discovered that a genetic variant responsible for a very light coat in dogs and wolves originated more than two million years ago in a now extinct relative of the modern wolf. |
| Metabolism changes with age, just not when you might think Posted: 12 Aug 2021 11:50 AM PDT Most of us remember a time when we could eat anything we wanted and not gain weight. But a new study suggests your metabolism, the rate at which you burn calories, actually peaks much earlier and starts its inevitable decline later than you might think. |
| New study shows the potential of DNA-based data-structures systems Posted: 12 Aug 2021 09:31 AM PDT Engineers have created new dynamic DNA data structures able to store and recall information in an ordered way from DNA molecules. They also analyzed how these structures are able to be interfaced with external nucleic acid computing circuits. |
| Posted: 12 Aug 2021 06:27 AM PDT Scientists used a new system to zoom in on an iconic RNA catalyst and a piece of viral RNA that's a potential target for COVID-19 treatments. |
| New technique illuminates DNA helix Posted: 12 Aug 2021 06:27 AM PDT Researchers have identified a new way to measure DNA torsional stiffness -- how much resistance the helix offers when twisted -- information that can potentially shed light on how cells work. |
| Silica nanostructure with chemo-enzymatic compartmentalization Posted: 12 Aug 2021 06:27 AM PDT A research team has recently synthesized a chemo-enzymatic nanostructure that can selectively synthesize one enantiomer while acting like an artificial organelle in the cell. |
| Protecting coral reefs more effectively from climate change Posted: 11 Aug 2021 01:28 PM PDT Identifying and researching different heat stress response patterns in corals will help to protect the world's reefs better from the effects of climate change. A new study describes the necessary test procedures and initial results. |
| A brief history of the cabbage butterfly’s evolving tastes Posted: 11 Aug 2021 01:28 PM PDT The cabbage butterfly, voracious as a caterpillar, is every gardener's menace. Turns out, these lovely white or sulfur yellow butterflies started trying to take over the planet long ago. Biologists used statistical methods to trace the path of Pieridae family butterflies as they diversified and their plant hosts fought back, over and over again. The study also finds that butterflies often regain hosts they haven't used for millions of years. |
| Rare new orchid species just discovered in the Andes Posted: 11 Aug 2021 10:15 AM PDT Three new endemic orchid species were just discovered in Ecuador. Lepanthes microprosartima, L. caranqui and L. oro-lojaensis are proof that Ecuador -- one of the world's megadiverse countries -- hides much more biodiversity waiting to be explored. |
| Lyme disease heightens risk of mental disorders, suicidality Posted: 11 Aug 2021 08:31 AM PDT A new study reports that patients hospitalized with Lyme disease had a 28 percent higher rate of mental disorders and were twice as likely to attempt suicide. Physicians and patients should be aware of the potential for psychiatric symptoms post-Lyme infection, particularly during the first year after diagnosis. |
| New technique identifies proteins in the living brain Posted: 11 Aug 2021 06:15 AM PDT In the new study, researchers designed a virus to send an enzyme to a precise location in the brain of a living mouse. Derived from soybeans, the enzyme genetically tags its neighboring proteins in a predetermined location. After validating the technique by imaging the brain with fluorescence and electron microscopy, the researchers found their technique took a snapshot of the entire set of proteins (or proteome) inside living neurons, which can then be analyzed postmortem with mass spectroscopy. |
| World's biodiversity maps contain many gaps Posted: 10 Aug 2021 11:30 AM PDT As the world's nations prepare to set new goals for protecting biodiversity, researchers have identified where data gaps continue to limit effective conservation decisions. |
