Rising atmospheric CO2 concentrations globally affect photosynthesis of peat-forming mosses

Scientists have developed ways to decipher effects of the CO2 rise during the past 100 years on metabolic fluxes of the key plant species in peatlands, mosses. Analyses of cellulose in peat cores collected by collaborating scientists working in five continents indicate that a CO2-driven increase in photosynthesis of mosses is strongly dependent on the water table, which may change the species composition of peat moss communities.

Citizen science data from Berlin show that urban areas can be a refuge for bats, if certain conditions are met

Urbanization is a notable threat to bat populations all over the world, especially through artificial light and the reduction of habitat and food supply. If certain conditions are met, some spaces within metropolitan areas can be suitable for bats, so managing these spaces appropriately could contribute to bat conservation. With the help of more than 200 citizen scientists in Berlin, a team of scientists examined these conditions and investigated how they affect the abundance and distribution of bat species. They conclude that maintaining a low level of artificial light at night is important for all bats in cities. In addition, access to vegetation and water bodies is essential for many of them.

Scientists have found evidence that a type of the antibiotic resistant superbug MRSA arose in nature long before the use of antibiotics in humans and livestock, which has traditionally been blamed for its emergence. Hedgehogs carry a fungus and a bacteria on their skin, and the two are locked in a battle for survival. The fungus secretes antibiotics to kill the bacteria, but in response the bacteria has evolved antibiotic resistance -- becoming Methicillin-resistant Staphylococcus aureus, or MRSA. Up to 60% of hedgehogs carry a type of MRSA called mecC-MRSA, which causes 1 in 200 of all MRSA infections in humans. Natural biological processes, not antibiotic use, drove the initial emergence of this superbug on hedgehogs around 200 years ago.

Can a goldfish drive a car on land?

Are animals' innate navigational abilities universal or are they restricted to their home environments? Researchers designed a set of wheels under a goldfish tank with a camera system to record and translate the fish's movements into forward and back and side to side directions to the wheels. By doing so, they discovered that a goldfish's navigational ability supersedes its watery environs.

New gene therapy approach offers a potential long-term treatment for limb-girdle muscular dystrophy 2B

Medical experts have developed a new pre-clinical gene therapy for a rare disorder, known as limb-girdle muscular dystrophy (LGMD) 2B, that addresses the primary cellular deficit associated with this disease. Using a single injection of a low dose gene therapy vector, researchers restored the ability of injured muscle fibers to repair in a way that reduced muscle degeneration and enhanced the functioning of the diseased muscle. The treatment was safe, attenuated fibro-fatty muscle degeneration, and restored myofiber size and muscle strength, according to a new study.

Custom finger clip offers a new way to measure blood pressure, other vitals

Monitoring a person's blood pressure on a regular basis can help health care professionals with early detection of various health problems such as high blood pressure, which has no warning signs or symptoms. However, many things can alter an accurate blood pressure reading, including a patient's nervousness about having their blood pressure taken at a doctor's office, otherwise known as 'white coat syndrome.' Now, researchers are customizing a commercial finger clip device to provide a rapid, noninvasive way for measuring and continually monitoring blood pressure. The device can also simultaneously measure four additional vital signs -- heart rate, blood oxygen saturation, body temperature and respiratory rate.

How plants respond to heat stress

Plants, like other organisms, can be severely affected by heat stress. To increase their chances of survival, they activate the heat shock response, a molecular pathway also employed by human and animal cells for stress protection. Researchers have now discovered that plant steroid hormones can promote this response in plants.

New route for regulating blood sugar levels independent of insulin

The discovery of insulin 100 years ago opened a door that would lead to life and hope for millions of people with diabetes. Ever since then, insulin, produced in the pancreas, has been considered the primary means of treating conditions characterized by high blood sugar (glucose), such as diabetes. Now, scientists have discovered a second molecule, produced in fat tissue, that, like insulin, also potently and rapidly regulates blood glucose. Their finding could lead to the development of new therapies for treating diabetes, and also lays the foundation for promising new avenues in metabolism research.

First time genome editing made possible on cells lining blood vessel walls

Researchers have developed a unique nanoparticle to deliver genome editing technology, including CRISPR/Cas9, to endothelial cells, which are cells that line blood vessel walls. This is the first time that vascular endothelial cells could be reached for genome editing, since the usual way to deliver CRISPR/Cas9 -- through a virus -- does not work for this cell type.

New method to complete genetic data

Genome sequencing is now much cheaper than it was, but still accounts for a large part of the costs in animal and plant breeding. One trick to reduce these costs is to sequence only a very small and randomly selected part of the genome and to complete the remaining gaps using mathematical and statistical techniques. Researchers have developed a new approach to do this.
