Could you love an AI?
What does love with “digital humans?” look like?
Is this the future of relationships?
In this TechFirst, we chat with Artem Rodichev, CEO of Ex-human and former head of AI at Replika.
Doctors have long known that inflammation plays a significant role in triggering heart attacks and strokes. Now for the first time, an anti-inflammatory drug is on the market to prevent these cardiovascular events.
“It is a game changer,” says Ian Neeland, MD, Director of Cardiovascular Prevention at University Hospitals Harrington Heart & Vascular Institute.
“We’ve known that low-grade, systemic inflammation is a powerful determinant of recurrent cardiovascular events. Colchicine is the first drug we have on the market for inflammation that reduces this risk,” says Dr. Neeland.
The risk of getting dementia may go up as you get older if you don’t get enough slow-wave sleep. Over-60s are 27 percent more likely to develop dementia if they lose just 1 percent of this deep sleep each year, a 2023 study found.
Slow-wave sleep is the third stage of a human 90-minute sleep cycle, lasting about 20–40 minutes. It’s the most restful stage, where brain waves and heart rate slow and blood pressure drops.
Deep sleep strengthens our muscles, bones, and immune system, and prepares our brains to absorb more information. Recently, research discovered that individuals with Alzheimer’s-related changes in their brain did better on memory tests when they got more slow-wave sleep.
Moiré materials, such as twisted bilayer graphene, are materials generally formed by stacking two or more layers of 2D materials on top of each other with a small lattice mismatch. This slight mismatch creates a unique pattern known as the moiré pattern, which is associated with desirable optical and electronic properties.
A new process for removing CO2 from the environment has been facilitated by a cobalt-copper catalyst.
Japan’s new state-of-the-art supercomputer, which is due to cost more than $750 million to build, is set to turn on by 2030.
Electrons typically travel at high speeds, zipping through matter unbound. In the 1930s, physicist Eugene Wigner predicted that electrons could be coaxed into stillness at low densities and cold temperatures, forming an electron ice that would later be called the Wigner crystal.
If you’ve ever seen yourself through a thermal imaging camera, you’ll know that your body produces lots of heat. This is in fact a waste product of our metabolism. Every square foot of the human body gives off heat equivalent to about 19 matches per hour.
Unfortunately, much of this heat simply escapes into the atmosphere. Wouldn’t it be great if we could harness it to produce energy? My research has shown this would indeed be possible. My colleagues and I are discovering ways of capturing and storing body heat for energy generation, using eco-friendly materials.

The composition of the products varies depending on the starting materials. Pure methane reacts—with very low yield—to give ethane, propane and hydrogen. The addition of oxygen increases the conversion, resulting mainly in CO2 as well as CO, ethylene, and water.
In the presence of water, aqueous methane reacts to give acetone and tertiary butyl alcohol; in the gas phase, it gives ethane and propane. When both water and oxygen are added, the reactions are strongly accelerated. In the aqueous phase, formaldehyde, acetic acid, and acetone are formed. If ammonia is also added, acetic acid forms glycine, an amino acid also found in space.
“Under gamma radiation, glycine can be made from methane, oxygen, water, and ammonia, molecules that are found in large amounts in space,” says Huang. The team developed a reaction scheme that explains the routes by which the individual products are formed. Oxygen (∙O2−) and ∙OH radicals play an important role in this. The rates of these radical reaction mechanisms are not temperature-dependent and could thus also take place in space.
Swedish scientists report a new breakthrough in technology that could transform optical communication in deep space, according to recently published research.
In a study led by a team at Chalmers University of Technology in Sweden, researchers have developed a silent amplifier and ultra-sensitive receiver that can facilitate high-fidelity transmissions over vast distances, showing promise for long-distance space communication.
