Cannabis-based medicine may reduce seizures for children with difficult-to-treat epilepsy

Taking a pharmaceutical formulation of cannabidiol, a cannabis-based medicine, cut seizures nearly in half for children with a rare and severe type of epilepsy called Dravet syndrome, according to a phase 3 study released today that will be presented at the American Academy of Neurology's 71st Annual Meeting in Philadelphia, May 4 to 10, 2019. Dravet syndrome, which starts in infancy, can lead to intellectual disability and frequent, prolonged seizures. Cannabidiol is derived from marijuana that does not include the psychoactive part of the plant that creates a "high."

Circadian rhythm disruption tips the cell-cycle balance toward tumor growth

Disrupting normal circadian rhythms promotes tumor growth and suppresses the effects of a tumor-fighting drug, according to a new study publishing April 30 in the open-access journal PLOS Biology by Yool Lee, Amita Sehgal, and colleagues at the University of Pennsylvania. The results provide mechanistic support for "chronotherapy," the delivery of cancer drugs timed to the endogenous circadian rhythm.

Researchers develop secure method for sending sensitive personal data from wearable tech

Smart watches. Pacemakers. Internet-connected glasses. These are devices designed to make life easier. And yet, all this wearable technology can be hacked. The devices send personal health information to your smartphone over the airways, so anyone with the know-how could scoop it up and steal it. But now, researchers at Northeastern have a better, more secure idea: Send data through your body.

New study identifies drug that can reverse hyperactivity induced by parasitic infection

When rodents get infected by Toxoplasma gondii, the single-celled brain parasite that causes toxoplasmosis, they become hyperactive risk-takers. In findings published this week in mBio, researchers show for the first time that it's possible to reverse that behavioral change. Surprisingly, the study also showed that the restoration of normal behavior resulted from reducing inflammation—and not from reducing the amount of parasites in the brain.

A simple technique allows robots to recognize touch and proximity

Researchers at the University of Hertfordshire have recently proposed an easy and configurable technique that enhances a robot's ability to perceive and interact with people in its surroundings. Their technique, presented in a paper pre-published on arXiv, utilizes affordable Bluetooth low energy (BLE) devices. Among its many possible applications, it could enhance therapy for children with autism spectrum disorder (ASD), allowing robots to act as mediators and monitor children in their surroundings.

Computer scientists design way to close 'backdoors' in AI-based security systems

It sounds like a plot out of a spy novel, with a touch of cyberpunk: An agent approaches a secure location, protected by a facial recognition system, accessible only to a head of state or CEO. Flashing an unusually shaped earring, the agent tricks the system into thinking they're that VIP, opening the door and exposing the secrets inside. The key—an undetectable "sleeper cell" was placed inside the AI behind the security system months or years earlier to grant access to anyone wearing the specified jewelry.

Alzheimer's in minibrains

In the majority of cases, dementia can be traced back to Alzheimer's disease. Its causes are not really understood yet. What is known is that plaques form from misfolded proteins and that there is an increase in neuronal cell death levels in the brain. However, the plaques don't necessarily go hand in hand with any symptoms. Dr. Thorsten Müller, Head of the research group Cell Signalling at the Chair of Molecular Biochemistry at Ruhr-Universität Bochum (RUB), suspects other deposits to cause the disease, namely ones that form in the nuclei. He intends to verify this hypothesis using tissue that resembles that of the brain. Rubin, the RUB's science magazine, published a report on his research.

LS2 report: Before the return of the cold

Since the start of January, the liquid helium flowing through the veins of the LHC's cooling system has gradually been removed the accelerator and, one by one, the eight sectors of the LHC have been brought back to room temperature. "It takes about four weeks to bring a single sector from its nominal temperature of 1.9 K (-271°C) back to room temperature," explains Krzysztof Brodzinski, an engineer working on the operation of the LHC's cryogenic system. At least 135 tonnes of helium are required to supply the whole of the LHC's cryogenic system. Once it has been brought up to the surface, some of this precious cooling agent is stored at CERN and the remainder (about 80 tonnes) is entrusted to the suppliers for the duration of LS2.

Malawi is testing a new malaria vaccine. But it's still early days

Malaria is a leading cause of death and illness around the world. Over 200 million cases are reported every year, and more than 400 000 people die. More than 90% of cases are reported in sub-Saharan Africa. Scientists have spent decades searching for an effective vaccine. Hence the recent excitement when Malawi's government announced it had launched a pilot programme for the world's first malaria vaccine, RTS,S (also known as Mosquirix), produced by the pharmaceutical company, GSK. It's the first vaccine to demonstrate significant reduction in malaria in children. The Conversation Africa's Ina Skosana asked immunologist Faith Osier about RTS,S.
