<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">Animal experiments have shown thatcombining a gut-hormone mimic such as semaglutide with another molecule is safe and leads to similar weight loss compared with semaglutide alone. The added molecule targets a brain-cell receptor that was linked to obesity in 2015. Fusing the molecule to a gut-hormone-mimicking peptide sidesteps the harmful side effects that usually come from blocking this receptor. The combination let the mice that had reached a weight-loss plateau with semaglutide reduce their weight further.</span><span style="color: black;">“</span><span style="color: black;">Very high marks for the novelty</span><span style="color: black;">” </span><span style="color: black;">of the research, says endocrinologist Daniel Drucker. </span><span style="color: black;">“</span><span style="color: black;">Let</span><span style="color: black;">’</span><span style="color: black;">s hope that we</span><span style="color: black;">’</span><span style="color: black;">ll see some proof of concept in the clinic.</span><span style="color: black;">”</span></span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">A building inspired by how some lizards shed defined tail segments to escape predators could save lives by isolating collapsing sections when it</span><span style="color: black;">’</span><span style="color: black;">s damaged. Current designs redistribute local failures to the rest of a structure through greater connectivity</span><span style="color: black;">— </span><span style="color: black;">but this can backfire when collapsed parts pull down the rest. Researchers built a two-story building to show thatpartial-strength connections between load-bearing columns can stop a collapse from propagating through the entire structure. The design uses common construction methods and materials, and would even meet existing building codes.</span></span></p>

More than 60% of the forested areas of developing countries provide carbon credits to high-income countries, with little impact on the economic well-being of forest communities. A new review shows that the forestry social science literature is dominated by these climate-mitigation interests. Scientists should consider research that aims to benefit all forest stakeholders, the editorial says.</span></span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">In 1967, epidemiologist Frederick Li attended a dinner party that would change the course of his career. Someone brought up the case of the Kilius family in Baltimore, in which the young father and his infant son had both been diagnosed with unusual cancers. Li knew the odds of this happening by chance were astronomical, so he visited the family to find out more. Over five generations, 14 out of 35 family members had developed cancers and 10 had died young. Li and his colleague Joseph Fraumeni published their findings in 1969, but it wasn</span><span style="color: black;">’</span><span style="color: black;">t until the 1990s thatthe underlying cause of Li-Fraumeni Syndrome was discovered: an inherited mutation in the p53 tumour-suppressor gene. Author Lawrence Ingrassia tells this story from a personal perspective in his new book, A Fatal Inheritance. Ingrassia is the only member of his family not to inherit the p53 gene.</span></span></p>

Eleven-year-old Tia Gordon first became ill in 2020. She was given painkillers and had her glasses prescription changed four times. Between November 2023 and January 2024, she vomited every day. Then, she started to have difficulty walking. A CT revealed a benign 3.5-cm brain tumour, and she underwent more than 10 hours of surgery to remove it. "Over more than three years, I took Tia to doctors, she was refused MRIs, she was refused to be seen by emergency paediatrics</span><span style="color: black;">… </span><span style="color: black;">but it took for her to be unable to walk for her to get the care she needed," her mother said.</span></span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">First formulated byAlbert Einstein in 1915, the theory of general relativity remains our best and most accurate understanding of how gravity works on medium to large scales.</span></span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">A nearly 130,000-year-old bear bone was deliberately marked with cuts and might be one of the oldest art pieces in Eurasia crafted by the Neanderthals, researchers say.</span></span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">The roughly cylindrical bone, which is about 4 inches long (10.6 centimeters), is adorned with 17 irregularly spaced parallel cuts.

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">In a small trial, some people with inherited vision loss experienced improvements in their sight after being treated with CRISPR.</span></span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">ACRISPR therapy injected directly into the eye shows promise in treating the most common form of inherited vision loss in children, an early trial suggests.</span></span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">This form of vision loss, calledLeber congenital amaurosis (LCA), is often evident at birth and results from the dysfunction or death of light-sensing cells called photoreceptors in the retina, at the back of the eye. Such problems happen due to mutations in any of at least 20 genes.</span></span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">Some of the most common causes of LCA are mutations in the gene that codes for centrosomal protein 290 (CEP290). More than three-quarters of the people with the disease carry a particular mutation that affects CEP290, which is crucial for photoreceptors to function properly.</span></span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">Parasites can cause a wide range of diseases in humans, ranging from short-term to lifelong.</span></span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">Parasitic diseases, which are passed on to people via parasites found in contaminated food, water, soil or bugs that bite humans, can be relatively uncommon in some parts of the world. In other regions, though, they can be absolutely devastating. Some parasites can cause illnesses that are temporary, but some trigger lifelong medical problems.</span></span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">Not all parasitic diseases are due to poor sanitation or poverty; you can be exposed to parasites regardless of your socioeconomic situation. Here are 32 parasites that can infect humans, including some well-known culprits and some you may not have heard of.</span></span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">Orcas that have been terrorizing boats in southwest Europe have just sank their fifth yacht in three years. And experts have warned that more attacks are likely in the coming months after the orcas unexpectedly switched up their behavior earlier this year.</span></span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">On Sunday (May 12), an unknown number oforcas (Orcinus orca) attacked the 49-foot-long (15 meters) sailing yacht named the Alboran Cognac in the Strait of Gibraltar</span><span style="color: black;">— </span><span style="color: black;">a narrow body of water between southern Spain and North Africa that separates the Atlantic Ocean and Mediterranean Sea. During the attack, which began at around 9 a.m. local time, the killer whales repeatedly rammed the boats hull and rudder, Reuters reported.</span></span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">The yachts two-person crew radioed for help and was rescued by a passing oil tanker. But the vessels hull sustained serious damage during the attack and the yacht began to take on water, which eventually caused it to sink, Reuters reported.</span></span></p>
