Optical metrology has long relied on interference principles, but a recent review highlights how orbital angular momentum (OAM) is redefining the field.
By integrating OAM into metrological tools, researchers are now capable of tracking motion in all directions, including rotational dynamics.

For decades, scientists have been trying to develop therapeutics for people living with Alzheimer’s disease, a progressive neurodegenerative disease that is characterized by cognitive decline. Given the global rise in cases, the stakes are high. A study published in The Lancet Public Health reports that the number of adults living with dementia worldwide is expected to nearly triple, to 153 million in 2050. Alzheimer’s disease is a dominant form of dementia, representing 60 to 70 percent of cases.
Recent approvals by the Food and Drug Administration have focused on medications that shrink the sticky brain deposits of a protein called amyloid beta. The errant growth of this protein is responsible for triggering an increase in tangled threads of another protein called tau and the development of Alzheimer’s disease — at least according to the dominant amyloid cascade hypothesis, which was first proposed in 1991.
Over the past few years, however, data and drugs associated with the hypothesis have been mired in various controversies relating to data integrity, regulatory approval, and drug safety. Nevertheless, the hypothesis still dominates research and drug development. According to Science, in fiscal year 2021 to 2022, the National Institutes of Health spent some $1.6 billion on projects that mention amyloids, about 50 percent of the agency’s overall Alzheimer’s funding. And a close look at the data for recently approved drugs suggests the hypothesis is not wrong, so much as incomplete.

A 25-year-old woman in China has had her Type 1 diabetes reversed through a groundbreaking new stem cell therapy treatment! As you can imagine, this represents a historic turning point in medical history. This revolutionary procedure has enabled her to create insulin on her own, relieving her of the constant daily hassle of injections. When this breakthrough eventually goes public, it will provide hope to millions worldwide dealing with this chronic condition.
According to Medlineplus, type 1 diabetes is classified as an autoimmune disorder in which the immune system erroneously attacks beta cells in the pancreas that produce insulin. Without insulin, your blood sugar levels can become dangerously elevated, leading to long-term damage to your vital organs. Managing this illness has generally required lifetime insulin therapy, which usually involves numerous daily injections or using insulin pumps. However, despite all of these measures, patients still face the risk of complications such as kidney damage, heart disease, and nerve issues.

The vast distances between stars make interstellar travel one of humanity’s most daunting challenges. Even the Voyager spacecrafts, now in interstellar space, would take tens of thousands of years to reach the nearest star, Alpha Centauri. To put this into perspective, Alpha Centauri is 277,000 astronomical units (AU) away—over 7,000 times the distance from Earth to Pluto. At current spacecraft speeds, a journey to our stellar neighbor would take an unimaginable 70,000 years. However, new ideas like the Sunbeam Mission offer a promising path forward, proposing innovative propulsion techniques that could shorten this timeline to mere decades.
What it eats: The carcasses of dead animals.
Why it’s awesome: These scavenger birds have an unexpected way of keeping predators away — by projectile vomiting stomach acid and semi-digested meat at their attackers.
Turkey vultures live in a range of habitats, including subtropical forests, shrublands and deserts. They have bald heads so that when they feast on carcasses, blood and guts don’t get trapped in their feathers.
I had a conversation with NVIDIA CEO Jensen Huang and we spoke about groundbreaking developments in physical AI and other big announcements made at CES. Jensen discusses how NVIDIA Cosmos and Omniverse are revolutionizing robot training, enabling machines to understand the physical world and learn in virtual environments — reducing training time from years to hours.
He shares insights on NVIDIA DRIVE AI’s autonomous vehicle developments, including their major partnership with Toyota, and talks about the critical role of safety in their three-computer system approach.
