Scientists have developed a new material capable of capturing the harmful chemical benzene from the polluted air, offering a potential solution for tackling a major health and environmental risk.
Could Earth be a cosmic sanctuary for observation? The Zoo Hypothesis suggests so.
In 1950, Italian-American physicist Enrico Fermi famously asked, “Where is everybody?” The question has since become the basis of the Fermi Paradox, addressing the conflict between the high probability of extraterrestrial life and the complete lack of evidence for its existence. Several hypotheses have been proposed to explain this, including the Zoo Hypothesis, first introduced in 1973 by Harvard astrophysicist John A. Ball. This theory posits that advanced alien civilizations may know of Earth and its inhabitants but choose to avoid contact, allowing humanity to develop naturally without interference.
Billionaire entrepreneur Elon Musk said on Tuesday (October 29) that Neuralink, the company he co-founded, should look to develop a brain implant which would alleviate neck and back pain. Neuralink develops makes Brain-Computer Interfaces (BCIs) which can be implanted in human brain. Musk’s latest comment came in a post he made on X (formerly Twitter), the social media platform he owns.
I am increasingly convinced that @Neuralink should prioritize making an implant that can eliminate back & neck pain.
Life Biosciences is a company co-founded by the celebrity geroscientist David Sinclair and is based on his Harvard team’s research into partial cellular reprogramming. In the heated race to translate this promising technology to the clinic, Life has emerged as one of the favorites, inching closer towards clinical trials in humans. Life is counting on its proprietary reprogramming technology that uses only three out of four classic reprogramming factors and on its strong team of scientists and managers. We talked to Dr. Sharon Rosenzweig-Lipson, Life’s Chief Scientific Officer, about the company’s journey, delving deep into the technology and its future.
I’ll start by saying that Life Biosciences is one of the most exciting companies in the longevity field. You might actually become the first company to have a partial reprogramming-based therapy approved.
At Life Biosciences, we’re focused on something that matters to everyone: helping people stay healthier as they age. We’re working on what we call cellular rejuvenation technologies, basically finding ways to turn back the clock in cells and make them more youthful. I came on board as Chief Scientific Officer about a year and a half ago, but I actually got to know the company pretty well before that. I consulted for them for a year, which gave me a chance to look under the hood, see the science they were doing, and I got really excited about what I saw.

In this episode of Cosmology 101, we learn how the detection of the Cosmic Microwave Background (CMB) validated the Big Bang Theory and led to the development of the concept of cosmic inflation.
Explore the challenges and ongoing debates in cosmology as scientists seek to uncover the true nature of the early universe and the origins of cosmic structure.

Physicists in Germany have used visible light to measure intramolecular distances smaller than 10 nm thanks to an advanced version of an optical fluorescence microscopy technique called MINFLUX. The technique, which has a precision of just 1 angstrom (0.1 nm), could be used to study biological processes such as interactions between proteins and other biomolecules inside cells.
In conventional microscopy, when two features of an object are separated by less than half the wavelength of the light used to image them, they will appear blurry and indistinguishable due to diffraction. Super-resolution microscopy techniques can, however, overcome this so-called Rayleigh limit by exciting individual fluorescent groups (fluorophores) on molecules while leaving neighbouring fluorophores alone, meaning they remain dark.
One such technique, known as nanoscopy with minimal photon fluxes, or MINFLUX, was invented by the physicist Stefan Hell. First reported in 2016 by Hell’s team at the Max Planck Institute (MPI) for Multidisciplinary Sciences in Göttingen, MINFLUX first “switches on” individual molecules, then determines their position by scanning a beam of light with a doughnut-shaped intensity profile across them.
Is AI going to take your job? Here’s what Nvidia CEO Jensen Huang told Bollywood star Akshay Kumar.

Accumulation of senescent cells drives aging and age-related diseases. Senolytics, which selectively kill senescent cells, offer a promising approach for treating many age-related diseases. Using a senescent cell-based phenotypic drug discovery approach that combines drug screening and drug design, we developed two novel flavonoid senolytics, SR29384 and SR31133, derived from the senolytic fisetin. These compounds demonstrated enhanced senolytic activities, effectively eliminating multiple senescent cell types, reducing tissue senescence in vivo, and extending healthspan in a mouse model of accelerated aging. Mechanistic studies utilizing RNA-Seq, machine learning, network pharmacology, and computational simulation suggest that these novel flavonoid senolytics target PARP1, BCL-xL, and CDK2 to induce selective senescent cell death. This phenotype-based discovery of novel flavonoid senolytics, coupled with mechanistic insights, represents a key advancement in developing next-generation senolyticss with potential clinical applications in treating aging and age-related diseases.
LJN and PDR are cofounders of Itasca Therapeutics, developing senotherapeutics for aging and age-related diseases. LJZ, LJN, PDR and the University of Minnesota have filed a provisional patent on the application of flavonoid analogs, including SR29384 and SR31133, as a strategy to treat age-related diseases.
