Newly discovered human antibody protects mice from a deadly malaria parasite

Scientists have discovered a human antibody that protected mice from infection with the deadliest malaria parasite, Plasmodium falciparum. The research findings provide the basis for future testing in humans to determine if the antibody can provide short-term protection against malaria, and also may aid in vaccine design. Currently, there is no highly effective, long-lasting vaccine to prevent malaria.

Researchers have reversed age-related endurance loss with a compound that promotes blood vessels

Researchers have reversed age-related endurance loss in mice by treating them with a compound that promotes new blood vessel growth. Their study found the compound, which reactivates longevity-linked sirutin proteins, promotes blood vessel and muscle growth, boosting endurance of elderly mice by up to 80 percent.

Researchers have developed new wound dressings that dramatically accelerates healing

Researchers have developed new wound dressings that dramatically accelerate healing and improve tissue regeneration. The two different types of nanofiber dressings, described in separate papers, use naturally-occurring proteins in plants and animals to promote healing and regrow tissue.

Scientists have used a combination of light and genetic engineering to control metabolism of a living cell

Researchers have used a combination of light and genetic engineering to controlling the metabolism, or basic chemical process, of a living cell. Building on techniques that already have transformed the field of neuroscience, the researchers used light to control genetically-modified yeast and increase its output of commercially valuable chemicals.

Engineers developed a tiny tooth-mounted sensor that can track what you eat

Engineers have developed miniaturized sensors that, when mounted directly on a tooth and communicating wirelessly with a mobile device, can transmit information on glucose, salt and alcohol intake. Researchers note that future adaptations of these sensors could enable the detection and recording of a wide range of nutrients, chemicals and physiological states.

Researchers design new lithium-air battery which can function after even 750 charge/discharge cycles

Lithium-air batteries — believed to be able to hold up to five times more energy than the lithium-ion batteries that power our phones, laptops and electric vehicles — have been tantalizing to battery researchers for years. But several obstacles have plagued their development. The batteries would work by combining lithium present in the anode with oxygen from the air to produce lithium peroxide on the cathode during the discharge phase. The lithium peroxide would be broken back down into its lithium and oxygen components during the charge phase.

Researchers developed a wearable system to monitor the stomach’s activity throughout the day

Researchers have developed a wearable, non-invasive system to monitor electrical activity in the stomach over 24 hours — essentially an electrocardiogram but for the gastro-intestinal (GI) tract. Applications include monitoring GI activity for patients outside of a clinical setting, which cuts down costs. Monitoring for longer periods of time also increases the likelihood of capturing abnormal events.

New computational method helps to identify rare tumor cell mutations with greater accuracy

A new computational method allows scientists to identify rare gene mutations in cancer cells with greater accuracy and sensitivity than currently available approaches. The technique is called Lancet and represents a major advance in the identification of tumor cell mutations, a process known as somatic variant calling.

New artificial intelligence technique dramatically improves the quality of medical imaging

Researchers have developed a new technique based on artificial intelligence and machine learning that should enable clinicians to acquire high-quality images from limited data.

World’s first continuous room-temperature solid-state maser built using diamond

The maser (microwave amplification by stimulated emission of radiation), the older microwave frequency sibling of the laser, was invented in 1954. However, unlike lasers, which have become widespread, masers are much less widely used because in order to function they must be cooled to temperatures close to absolute zero (-273°C). However, this new study reports for the first time a maser that can act continuously at room temperature.
