Researchers from The University of Queensland have discovered the active compound from an edible mushroom that boosts nerve growth and enhances memory.
Professor Frederic Meunier from the Queensland Brain Institute said the team had identified new active compounds from the mushroom, Hericium erinaceus.

Imagine going for an MRI scan of your knee. This scan measures the density of water molecules present in your knee, at a resolution of about one cubic millimeter – which is great for determining whether, for example, a meniscus in the knee is torn. But what if you need to investigate the structural data of a single molecule that’s five cubic nanometers, or about ten trillion times smaller than the best resolution current MRI scanners are capable of producing? That’s the goal for Dr. Amit Finkler of the Weizmann Institute of Science’s Chemical and Biological Physics Department.
In a recent study (Physical Review Applied, “Mapping Single Electron Spins with Magnetic Tomography”), Finkler, PhD student Dan Yudilevich and their collaborators from the University of Stuttgart, Germany, have managed to take a giant step in that direction, demonstrating a novel method for imaging individual electrons. The method, now in its initial stages, might one day be applicable to imaging various kinds of molecules, which could revolutionize the development of pharmaceuticals and the characterization of quantum materials.

Not only were women in ancient Egypt responsible for the nurturance and admonition of children, but they could also work at a trade, own and operate a business, inherit property, and come out well in divorce proceedings. Some women of the working class even became prosperous. They trained in medicine as well as in other highly skilled endeavors. There were female religious leaders in the priesthood, but in this instance, they were not equal to the men. In ancient Egypt, women could buy jewelry and fine linens. At times, they ruled as revered queens or pharaohs.
The role of women in ancient Egypt diminished during the late dynastic period but reappeared within the Ptolemaic dynasty. Both Ptolemy I and II put the portraits of their wives on the coins. Cleopatra VII became a very powerful figure internationally. However, after her death, the role of women receded markedly and remained virtually subservient until the 20th century.

Patients who received the treatment had less severe brain symptoms and better daily functioning 90 days after the stroke, as compared with those who received clot treatment and a placebo medication.
Butylphthalide is approved and available for use in China, where the study was done. But the medication hasn’t been approved for use by the FDA.
“This is the first trial to show the benefit of using a medication that protects the brain from damage caused by a lack of oxygen to brain tissue. The medication was given to patients with acute ischemic stroke who were also receiving treatment to restore blood flow to the brain,” says co-author Baixue Jia, MD, a doctor of interventional neuroradiology at the Beijing Tiantan Hospital and the China National Clinical Research Center for Neurological Diseases in Beijing.

University of Virginia Health neuroscientists have discovered a potential way to disrupt the chronic inflammation responsible for multiple sclerosis.
Immunotherapy is currently a treatment option for breast cancer, melanoma, leukemia, and non-small cell lung cancer.
Researchers are currently looking at using immunotherapy as a treatment for other types of cancer, including prostate cancer, brain cancer, and ovarian cancer.

Our DNA holds thousands of dead genes and we’ve only just begun to unravel their stories. But one thing is already clear: we’re not just defined by the genes that we’ve gained over the course of our evolution, but also by the genes that we’ve lost along the way.

This process is no less relevant to humans than any other species in nature, but since our species is such an evolutionary newcomer, the extent of its influence — and how it might work today — is still difficult to pin down.
The challenge: A team of researchers in Greece and Ireland, led by Nikolaos Vakirlis at the Alexander Fleming Biomedical Sciences Research Center in Athens, argues that a key to understanding human evolution lies with short sequences of DNA named “open reading frames” (ORFs). These structures are small sections of the genome that encode tiny protein molecules — microproteins — which can perform a diverse range of crucial biological tasks, from regulating muscle performance to alerting cells to damaging stresses.
Due to their minuscule sizes, ORFs are notoriously difficult to study. Because of this, their full relevance has gone under the radar in mainstream genomics research until recently, and even today, they still aren’t considered to be proper genes in themselves. For Vakirlis’ team, this potential oversight masks the fact that the microproteins encoded by ORFs can develop their own de novo sequences over generations, which may eventually develop into new genes.
