A revolutionary 60-minute therapy for high blood pressure could allow patients to throw their tablets away for good.
The unlikely remedy involves blasting nerves in the kidneys with sound waves to stop them sending signals to the brain that drive up blood pressure.
It could slash the risk of heart attacks and strokes, two of Britain’s biggest killers.
Scientists at Stanford University say they’ve devised antibodies that block a specific gene related to brain aging — and that it’s giving old mice the cognitive prowess of younger ones.
“The mice became smarter,” senior author Tony Wyss-Coray said in a statement. “Blocking [the gene] CD22 on their microglia restored their cognitive function to the level of younger mice. CD22 is a new target we think can be exploited for treatment of neurodegenerative diseases.”
The humble honeybee can use symbols to perform basic maths including addition and subtraction, shows new research published today in the journal Science Advances.
Despite having a brain containing less than one million neurons, the honeybee has recently shown it can manage complex problems – like understanding the concept of zero.
Through a new approach dubbed AMBAR, the biotechnology company Grifols has attempted to reduce the amount of harmful, Alzheimer’s disease-causing amyloid beta in the brain by collecting it with a blood protein called albumin and draining it out of the bloodstream. This approach differs from the previous antibody and catabody approaches and offers new hope for sufferers of this neurodegenerative disease.
What is Alzheimer’s disease?
Alzheimer’s disease, named after its discoverer, is a slow and progressive disease that causes the degradation of the brains of its sufferers. This leads to memory loss, a decrease in problem-solving abilities, changes in personality, and other symptoms. It is associated with the accumulation of tau and amyloid beta in the brain.
According to a report in the official magazine of its Defense Ministry, Russian “supersoldiers” are able to use “parapsychology” techniques to crash enemy computers, access the minds of foreign soldiers, and read documents inside locked safes — abilities they gained, according to the article, from telepathic dolphins they can now communicate with.
The report is almost certainly nonsense. But it does raise questions about the ambitions — and perhaps dysfunctions — of Russia’s military.

French director, Luc Besson, talks to GQ ahead of the UK release of action-thriller Lucy.
The human brain can grow new neurons up to age 97.
A group of monkeys were found to have “human-like” brain development, including faster reactions and better memories, after a joint Sino-American team of researchers spliced a human gene into their genetic makeup.
Researchers from the Kunming Institute of Zoology at the Chinese Academy of Sciences (CAS), and the University of North Carolina in the United States modified the genes of 11 monkeys (eight first-generation and three second-generation) with the addition of copies of the human gene MCPH1.
Microcephalin (MCPH1) is a key factor in our brain development and, in particular, eventual brain size. Mutations in the gene can lead to the developmental disorder microcephaly, which is characterized by a tiny brain.
Agree or Disagree?
According to two papers published in Cell on January 11, 2018, the making of memories and the processes of learning resemble, of all things, a viral infection. It works like this: The shells that transport information between neurons are assembled by a gene called Arc. Experiments conducted by two research teams revealed that the Arc protein that forms a shell, functions much like a Gag, a gene that transports a virus’s genetic material between cells during an infection. For example, the retrovirus HIV uses a Gag in exactly this manner.
