 | European Space Agency agrees record budget to meet new challengesEuropean Space Agency (ESA) members agreed Thursday a record 14.4 billion euros budget, promising to maintain Europe's place at the top table as the United States and China press ahead and industry disruptors such as Elon Musk's Space X present new challenges. |
Technology news
 | Highly performing and wafer-scalable aligned carbon nanotube transistorsAs we enter the wireless world of 5G, communications in the millimeter-wave band (i.e., from 30 to 300 GHz) will become increasingly important, particularly for high-speed wireless data-transfer applications. The trouble is that at these small wavelengths, the on-circuit signal strength degrades rapidly, thus requiring the circuit to be highly integrated into the smallest possible footprint. To best implement this, the high-frequency transistor technology needs to be compatible with the workhorse technology of digital electronics: complementary metal-oxide-semiconductors (CMOSs). |
 | Polish firm's drones, from lifesaver to invisible model, take to the skiesSilently the eight propellers of the Hermes V8MT drone begin to spin and the large yellow aircraft rises up, locates its direction and moments later disappears into the sky in southern Poland. |
 | Ambient Mode announced for some Android phonesAs far as Android announcements go, the one for Google Assistant Ambient Mode was more like a pleasant cowbell ring than a blasting trumpet but nonetheless it is a new feature and will please those who like the idea of being reminded about information important to them. |
 | Nissan invests in production to prepare for electric ageNissan is investing 33 billion yen ($303 million) in its flagship auto plant in Japan's Tochigi prefecture in a first rollout of a production system geared toward electric vehicles. |

 | Germany aims to shield tech firms from foreign takeoversGermany's economy ministry said Thursday it planned to tighten rules on non-EU takeovers of hi-tech firms, against a backdrop of growing alarm about Chinese firms buying up German know-how. |
Medicine & Health news
 | Popular heartburn drugs may up odds of stomach bug(HealthDay)—If you're one of the millions who rely on medications known as proton pump inhibitors for relief from heartburn, you may be at higher risk of illness from a stomach bug, new research suggests. |
 | Placenta changes could mean male offspring of older moms more likely to develop heart problemsPlacenta changes could mean male offspring of older mums more likely to develop heart problems in later life, rat study finds. |
 | Researchers identify protein that governs human blood stem cell self-renewalUCLA scientists have discovered a link between a protein and the ability of human blood stem cells to self-renew. In a study published today in the journal Nature, the team reports that activating the protein causes blood stem cells to self-renew at least twelvefold in laboratory conditions. |
 | Study warns helmets don't offer full protection on slopesFor several years now, it has been almost de rigueur for skiers and snowboarders to strap on a helmet amid rising concerns about safety on the slopes. |
 | Pharmacist-led interventions may help prevent cardiovascular diseaseWith their expertise in the safe and effective use of medications, pharmacists can help in the management of chronic diseases. A review and analysis published in the British Journal of Clinical Pharmacology indicates that initiatives—such as patient education, medication review, and physical assessments—led by pharmacists can make important contributions to the prevention of cardiovascular disease. |
 | Informed consent for heart procedure: most patients overestimate benefitsMost patients do not understand or recall information given to them before heart procedures. For example, many patients mistakenly believe that opening blocked arteries will cure them of heart disease. That's one of the findings of a study about informed consent published today in the European Journal of Cardiovascular Nursing, a journal of the European Society of Cardiology (ESC). |
China confirms fourth plague caseA fourth person in northern China has been diagnosed with the plague this month, officials confirmed, as a flea and rat eradication campaign was carried out by local government. | |
 | Does MRI screening benefit women with extremely dense breasts?(HealthDay)—Health experts already know that women with extremely dense breasts don't get the same benefit from mammography as women without very dense breast tissue. But what hasn't been clear is if MRI screening might spot cancers that mammography didn't. |
 | Practice organization not tied to family physician burnout(HealthDay)—Burnout among family physicians should not be attributed solely to practice organization, according to a study published in the November/December issue of the Annals of Family Medicine. |
 | Half of all women with HIV are diagnosed late in EuropeMany women in the WHO European Region, particularly those in their 40s, are diagnosed at a late stage of HIV infection when their immune system is already starting to fail. They are three to four times more likely to be diagnosed late than younger women. |
Combine chemical probe resources to optimize biomedical research, scientists urgeA new report urges biomedical researchers to use online web resources very carefully, taking into account their complementary benefits and weaknesses, when selecting small-molecule chemical probes to help answer their research questions. | |
 | Got chronic heartburn? Easy does it during the Thanksgiving feast(HealthDay)—The turkey, stuffing, cranberries, green bean casserole and mashed potatoes on the Thanksgiving table may look tempting, but if you have gastroesophageal reflux disease (GERD) you should proceed with caution, experts say. |
 | Don't let allergies spoil your holidays(HealthDay)—Asthma or allergies can put a damper on holiday gatherings. But there are ways you can stay healthy, the American College of Allergy, Asthma and Immunology says. |
Fears for infants in Samoa as measles deaths mountMeasles infections continued to climb steeply in Samoa Thursday as a mass vaccination programme fails to reach the infants most vulnerable to the deadly epidemic. | |
Biology news
 | Researchers demonstrate machine-guided engineering of AAV capsidsAdeno-associated viruses (AAVs) have become the go-to vehicle for delivering therapeutic gene cargo to target tissues for the recent wave of gene therapies that are in development in academic and biotechnology laboratories. However, natural AAVs do not specifically target diseased cells and tissues, and they can be recognized by the immune system in ways that limit therapeutic success. To improve AAVs, synthetic biologists have been taking a "directed evolution" approach in which they randomly mutate specific amino acid building blocks of the capsid proteins that form the shell of the virus and directly contact target cells. By evaluating which changes can route the virus to target tissues and successively layering mutations on top of each other in an arduous iterative process, they aim to improve desirable AAV traits. |
 | Animals could help humans monitor oceansSharks, penguins, turtles and other seagoing species could help humans monitor the oceans by transmitting oceanographic information from electronic tags. |
 | New vaccine will stop the spread of bovine tuberculosisScientists at the University of Surrey have developed a novel vaccine and complementary skin test to protect cattle against bovine tuberculosis (bovine TB). |
