Researchers at Baylor College of Medicine, Stanford University School of Medicine and collaborating institutions report in the journal Cell the discovery of BHB-Phe, a novel compound produced by the body that regulates appetite and body weight through interactions with neurons in the brain.

Until now, BHB has been known as a compound produced by the liver to be used as fuel. However, in recent years, scientists have found that BHB increases in the body after fasting or exercise, prompting interest in investigating potential beneficial applications in obesity and diabetes.

In the current study, the team at Stanford University led by co-corresponding author Dr. Jonathan Z. Long, associate professor of pathology, discovered that BHB also participates in another metabolic pathway. In this case, an enzyme called CNDP2 joins BHB to amino acids. Furthermore, the most abundant BHB-amino acid, BHB-Phe, can influence body weight and metabolism in animal models.

In this respect, I believe regulators have fallen short. In a world facing ongoing cyber threats, the standards for cybersecurity are set surprisingly low that their rules typically only recognize encryption of all stored data as a requirement. This is despite the fact that encryption—not firewalls, monitoring, identity management or multifactor authentication—is the purpose-built technology for protecting data against the strongest and most capable adversaries. Stronger regulations are needed to ensure encryption becomes a mandated standard, not just an optional recommendation.

Fortunately, companies need not wait until regulators realize their folly and can opt to do better today. Some companies already have. They approach data security as an exercise in risk mitigation rather than passing an audit. From this perspective, data encryption quickly becomes an obvious requirement for all their sensitive data as soon as it is ingested into a data store.

Another beneficial development is that encryption has become easier and faster to implement, including the ability to process encrypted data without exposure, a capability known as privacy-enhanced computation. While there will always be some overhead to adopting data encryption, many have found that the return on investment has shifted decisively in favor of encrypting all sensitive data due to its substantial security benefits.

Results from a recent clinical trial led by physicians at Emory University and Grady Health System indicate that a twice-yearly injection of Lenacapavir offers a 96% reduced risk of HIV infection overall, significantly more effective than the daily oral PrEP.

When it is solicited, the research emphases of E.9 Space Biology: Research Studies will fall under two broad categories: Precision Health and Space Crops.

For Precision Health-focused studies, investigators may propose to use any non-primate animal model system, and any appropriate cell/tissue culture/ microphysiological system/ organoid or microbial models, that are supported by the chosen platform. For Space Crop-focused studies, applicants may propose to use any plant model system, and when appropriate, any microbial or plant and microbial model systems that are supported by the chosen platform.

This opportunity will include five different Project Types: Research Investigations, Early Career Research Investigations, New NASA Investigators, GeneLab Analytical Investigations, and Tissue Sharing Investigations.

The Adaptive Immunity and Immunoregulation Section (AIIS) in the Laboratory of Allergic Diseases at #NIAID is seeking an exceptional candidate for a postdoctoral fellowship position.

The National Institute of Allergy and Infectious Diseases (NIAID), one of the largest institutes in the National Institutes of Health (NIH), and part of the Department of Health and Human Services (HHS), conducts and supports basic and applied research to better understand, treat, and ultimately prevent infectious, immunologic, and allergic diseases.

A postdoctoral fellowship position is available immediately in the Adaptive Immunity and Immunoregulation Section (AIIS) within the Laboratory of Allergic Diseases, NIAID. AIIS seeks highly motivated and collaborative candidates with a strong publication record who are capable of independent reasoning and excited about learning new technologies.

AIIS aims to define the cellular and molecular mechanisms controlling the balance between protective and pathogenic adaptive immune responses to allergens and pathogens. With a particular focus on memory T and B cells and T follicular helper (Tfh) cells, the lab utilizes state-of-the-art cellular and molecular approaches, including in vivo models of infection and allergy, multi-color flow cytometry, adoptive transfer experiments, cell fate tracking experiments, bone marrow chimeras, parabiosis surgery, imaging, conditional knockout and transgenic models, RNA-Seq, and single-cell technologies to characterize memory B-and T-cell responses in different models of food and respiratory allergens and infections.

A new study from The Hospital for Sick Children (SickKids) and Institut Curie reveals how stem cells sense and respond to their environment, with implications for inflammatory bowel disease and colorectal cancer.

Stem cells constantly adapt to their environment to maintain organ and tissue health, informed by chemical signals and physical forces. When they do not function as intended, stem cells can result in a number of health conditions including inflammatory bowel disease (IBD) and colorectal (bowel) cancer, where they continue to divide until a tumor forms.

Until now, how stem cells sense the physical forces around them has remained unclear, but novel findings published in Science led by Dr. Meryem Baghdadi, a former SickKids postdoctoral researcher, Dr. Tae-Hee Kim at SickKids and Dr. Danijela Vignjevic at Institut Curie, has revealed that stem cells depend on two ion channels, called PIEZO1 and PIEZO2, for their survival.

A cancer therapy that prompts the body’s immune defenses against viruses and bacteria to attack tumors can make patients more vulnerable to heart attack and stroke. A possible explanation for this side effect is that the treatment interferes with immune regulation in the heart’s largest blood vessels, a new study suggests.

Led by researchers at NYU Langone Health and its Perlmutter Cancer Center, the new work focused on a potent class of cancer-fighting drugs called immune checkpoint inhibitors. These medications work by blocking molecules embedded on the surface of cells—immune checkpoints—which normally serve as “brake pedals” that prevent excess immune activity, or inflammation. Some tumors are known to hijack these checkpoints to weaken the body’s defenses, so by blocking the checkpoints, the treatments enable the immune system to kill tumor cells.

However, this treatment type may also trigger damaging levels of inflammation in the heart, brain, stomach, and other organs, the researchers say. For example, past studies have shown that about 10% of those with atherosclerosis, the buildup of hardened fatty deposits (plaques) within artery walls, have a heart attack or stroke following cancer treatment. However, the specific mechanisms behind this issue had until now remained unclear.

Summary: Researchers identified specific plant compounds that provide antioxidant and neuroprotective effects, contributing to brain health beyond basic nutrition. By analyzing plant-based foods like lemon balm, sage, and elderberry, scientists linked compounds such as phenolics and terpenes to benefits like reducing oxidative stress and scavenging harmful reactive species.

Quercetin-rich foods, such as Queen Garnet plum and clove, showed strong potential to prevent neuron-like cell damage. This study sheds light on how plant-based diets and supplements could support brain health and manage neuroinflammation-related conditions.
