Artificial intelligence (AI) is on the rise. Until now, AI applications generally have 'black box' character: How AI arrives at its results remains hidden. A cheminformatics scientist has now developed a method that reveals how certain AI applications work in pharmaceutical research. The results are unexpected: the AI programs largely remembered known data and hardly learned specific chemical interactions when predicting drug potency. Read more ›

A research team has presented its findings on the functioning of an atypical cryptochrome protein (Cry). These proteins are found in a variety of organisms, and they are often involved in light-controlled biological processes. The marine bristle worm Platynereis dumerilii, for example, employs a special Cry protein designated L-Cry to distinguish between sunlight and moonlight as well as between different moon phases. This is essential for the worms to synchronize... Read more ›

A surprising thing happened when researchers began exploring whether early-life stress compounds the effects of a childhood head injury on health and behavior later in life: In an animal study, stress changed the activation level of many more genes in the brain than were changed by a bump to the head.

Fasting interventions, which involve alternating periods of fasting and refeeding, are generally thought to improve health. But these interventions don't work as well in old animals. The question is: Why? By studying the short-lived killifish, researchers have shown that older fish deviate from a youthful fasting and refeeding cycle, and instead enter a state of perpetual fasting, even when ingesting food. However, the benefits of refeeding after fasting in old... Read more ›

While currently available PCSK9 inhibitor medications to lower cholesterol must be administered every few weeks by injection, a new, investigational PCSK9 inhibitor called recaticimab safely lowered bad cholesterol more than 50% when injected every 1-3 months, depending on dose. Read more ›

Semaglutide reduced cardiovascular events by 20% in adults with overweight or obesity and established cardiovascular disease who do not have diabetes, according to new research.  Semaglutide is primarily prescribed for adults with type 2 diabetes but is also approved for chronic weight management in adults with obesity or overweight and have at least one other health issue. In the trial, patients treated with semaglutide lost an average of 9.4% of... Read more ›

The ventilation technique, also known as rescue breathing, commonly used during cardiopulmonary resuscitation (CPR) for people with cardiac arrest is often performed poorly by professional emergency responders, and this ineffective strategy is linked to significantly worse patient survival rates, according to a new study. Ventilation involves administering breaths to a patient to provide life-sustaining oxygen and inflate the lungs when they stop breathing or during cardiac arrest, when the heart... Read more ›

Humankind risks getting stuck in 14 evolutionary dead ends, ranging from global climate tipping points to misaligned artificial intelligence, chemical pollution, and accelerating infectious diseases, finds a new major assessment by scientists from multiple different disciplines. To break these trends, humans must become self-aware of our common futures. Read more ›

Nearly everyone can lower their blood pressure, even people currently on blood pressure-reducing drugs, by lowering their sodium intake, reports a new study. It found 70-75% of all people, regardless of whether they are already on blood pressure medications or not, are likely to see a reduction in their blood pressure if they lower the sodium in their diet.  Losing one teaspoon of salt a day results in systolic blood...

A research team has developed a reversible, water-based glue that has good adhesion in the neutral pH range, but can be detached again in strongly acidic or alkaline environments. The novel adhesive system, which is based on electrostatic interactions, has bond strengths somewhere between those of structural adhesives and pressure-sensitive adhesives. The new adhesive also bonds 'difficult' surfaces such as water-repellent polypropylene. Read more ›

A research team has developed an intravenous (IV) needle that softens upon insertion, minimizing risk of damage to blood vessels and tissues. Once used, it remains soft even at room temperature, preventing accidental needle stick injuries and unethical multiple use of needle. A thin-film temperature sensor can be embedded with this needle, enabling real-time monitoring of the patient's core body temperature, or detection of unintended fluid leakage, during IV medication.

Chemists have developed a new polyurethane production technique using CO2 to create new types of easily recyclable plastics that uses more sustainable materials to produce plastics with properties similar to conventional petro-sourced plastics. This new technology is emerging as a potential solution for the development of sustainable plastics with a wide range of properties that can easily meet the needs of most of our everyday applications.
