First insights into engineering crystal growth by atomically precise metal nanoclusters have been achieved in a study performed by researchers in Singapore, Saudi Arabia and Finland. The work was published in Nature Chemistry.
Ordinary solid matter consists of atoms organized in a crystal lattice. The chemical character of the atoms and lattice symmetry define the properties of the matter, for instance, whether it is a metal, a semiconductor or and electric insulator. The lattice symmetry may be changed by ambient conditions such as temperature or high pressure, which can induce structural transitions and transform even an electric insulator to an electric conductor, that is, a metal.
Larger identical entities such as nanoparticles or atomically precise metal nanoclusters can also organize into a crystal lattice, to form so called meta-materials. However, information on how to engineer the growth of such materials from their building blocks has been scarce since the crystal growth is a typical self-assembling process.
In a multi-year research program coordinated by the two directors of. NeuroRestoreโGrรฉgoire Courtine, a neuroscience professor at EPFL, and Jocelyne Bloch, a neurosurgeon at Lausanne University Hospital (CHUV)โpatients who had been paralyzed by a spinal cord injury and who underwent targeted epidural electrical stimulation of the area that controls leg movement were able to regain some motor function.
In the new study by. NeuroRestore scientists, appearing today in Nature, not only was the efficacy of this therapy demonstrated in nine patients, but the improved motor function was shown to last in patients after the neurorehabilitation process was completed and when the electrical stimulation was turned off. This suggested that the nerve fibers used for walking had reorganized. The scientists believe it was crucial to understand exactly how this neuronal reorganization occurs in order to develop more effective treatments and improve the lives of as many patients as possible.
Climate TRACE is a global non-profit coalition created to make meaningful climate action faster and easier by independently tracking greenhouse gas (GHG) emissions with unprecedented detail and speed.
They harness satellite imagery and other forms of remote sensing, artificial intelligence, and collective data science expertise to track human-caused GHG emissions with unprecedented detail and speed.
Climate TRACEโs emissions inventory is the worldโs first comprehensive accounting of GHG emissions based primarily on direct, independent observation. Our innovative, open, and accessible approach relies on advances in technology to fill critical knowledge gaps for all decision makers that rely on the patchwork system of self-reporting that serves as the basis for most existing emissions inventories.
Google has removed two new malicious dropper apps that have been detected on the Play Store for Android, one of which posed as a lifestyle app and was caught distributing the Xenomorph banking malware.
โXenomorph is a trojan that steals credentials from banking applications on usersโ devices,โ Zscaler ThreatLabz researchers Himanshu Sharma and Viral Gandhi said in an analysis published Thursday.
โIt is also capable of intercepting usersโ SMS messages and notifications, enabling it to steal one-time passwords and multi-factor authentication requests.โ
Recent progress in generative models has paved the way to a manifold of tasks that some years ago were only imaginable. With the help of large-scale image-text datasets, generative models can learn powerful representations exploited in fields such as text-to-image or image-to-text translation.
The recent release of Stable Diffusion and the DALL-E API led to great excitement around text-to-image generative models capable of generating complex and stunning novel images from an input descriptive text, similar to performing a search on the internet.
With the rising interest in the reverse task, i.e., image-to-text translation, several studies tried to generate captions from input images. These methods often presume a one-to-one correspondence between pictures and their captions. However, multiple images can be connected to and paired with a long text narrative, such as photos in a news article. Therefore, the need for illustrative correspondences (e.g., โtravelโ or โvacationโ) rather than literal one-to-one captions (e.g., โairplane flyingโ).
Longevity is not yet considered an official medical term, and aging is not officially considered a disease but a natural occurrence in every living thing.
However, some biologists, researchers and practicing doctors believe this approach should change, and they are striving to discover the mechanisms of aging in humans. In doing so, they are creating age clocks by defining biomarkers for measuring biological age, exploring the best lifestyle habits and natural supplements, and inventing new drugs that could stop us from getting older.
Longevity has been on the radar of crypto leaders for some time already, which is not a surprise given that the industry promises to improve humankind through innovation. Indeed, one prominent event in the longevity industry, the Longevity Investors Conference, is organized by Marc P. Bernegger and Tobias Reichmuth, who were previously involved with the Crypto Finance Group.
Ever wonder why some 90-year olds donโt seem to slow down and seem. to retain the mental and physical capacity of someone half their age? Do they have good genes? Or is there a way that all of us can get older without getting old?
Thatโs what Dr. Nir Barzilai, founder of the Institute for Aging Research at the Albert Einstein College of Medicine, set out to answer in his book, Age Later.
Dr. Nir joined us for a live Q + A discussion on Zoom. Whether youโve read Age Later or not, you wonโt want to miss this. Because by the end of the discussion, youโll know how to turn back the clock on aging.
